Referring to fig. 1, an absorption refrigeration device 100 includes an integrated cold source cycle generator 10, a condenser 20, and an evaporator 30. The condenser 20 is connected between the integrated cold source circulation generator 10 and the evaporator 30, and the evaporator 30 is also connected with the integrated cold source circulation generator 10.

Specifically, a refrigerant solution is stored in the integrated cold source circulation generator 10, the integrated cold source circulation generator 10 exchanges heat with the in-vehicle power system 40, and after waste heat of the power system 40 is absorbed, the refrigerant solution is evaporated into refrigerant vapor. The refrigerant vapor enters the condenser 20, and the condenser 20 condenses the refrigerant vapor into a liquid refrigerant. The liquid refrigerant continues to enter the evaporator 30, the evaporator 30 exchanges heat with the passenger compartment 50 in the vehicle, and after the heat of the passenger compartment 50 is absorbed, the liquid refrigerant is evaporated into refrigerant vapor. The refrigerant vapor finally flows back into the absorber, and the remaining refrigerant solution in the absorber absorbs the refrigerant vapor, thereby realizing the refrigerant solution flowing circulation in the integrated cold source circulation generator 10 and the refrigeration function of the absorption refrigeration device 100.

Referring to fig. 2 and 3, the integrated cold source circulation generator 10 includes an absorption end 1 and a generation end 2 separately disposed up and down, and the absorption end 1 and the generation end 2 are respectively used for storing a refrigerant solution.

The bottom of the absorption end 1 is provided with a first outlet 11 and a second inlet 12, and the top of the absorption end 1 is provided with a third inlet 13; the bottom of the generation end 2 is provided with a first inlet 21 and a second outlet 22, and the top of the generation end 2 is provided with a third outlet 23.

The first outlet 11 is communicated with the first inlet 21 through the first pipeline 3, so that the refrigerant solution in the absorption end 1 flows to the generation end 2 along the first pipeline 3; the second outlet 22 is communicated with the second inlet 12 through a siphon line 4, and the siphon line 4 reflows the refrigerant solution in the generation end 2 into the absorption end 1 through thermosiphon so as to realize the flowing circulation of the refrigerant solution between the absorption end 1 and the generation end 2.

Specifically, the refrigerant solutions stored in the absorption end 1 and the generation end 2 are refrigerant solutions composed of a low boiling point refrigerant and a high boiling point absorbent. The refrigerant solution may be water as the refrigerant, for example: refrigerant solutions such as water-lithium bromide, water-lithium chloride, water-lithium iodide, water-calcium chloride, and the like; the refrigerant solution may also be ammonia as a refrigerant, for example: ammonia-water, ethylamine-water, methylamine-water, sodium thiocyanate-ammonia and other refrigerant solutions; the refrigerant solution may also be an alcohol as a refrigerant, for example: refrigerant solutions such as methanol-lithium bromide, methanol-zinc bromide, methanol-lithium bromide-zinc bromide, and the like.

After the generation end 2 absorbs heat, the low-boiling-point refrigerant in the refrigerant solution in the generation end 2 can be evaporated into high-temperature refrigerant vapor, so that a gas-liquid mixture is formed in the generation end 2, the volume is expanded, and the density is reduced. By using the density difference between the absorption end 1 and the generation end 2 as a driving force, the refrigerant solution in the generation end 2 can rise along the siphon pipeline 4 and flow back into the absorption end 1; the refrigerant solution in the absorption end 1 can flow to the generation end 2 along the first pipeline 3, so that the refrigerant solution flow circulation between the absorption end 1 and the generation end 2 is realized.

The integrated cold source circulation generator 10 integrates an absorber and a generator in the conventional absorption refrigeration device 100, simplifies the structure of the absorption refrigeration device 100, reduces the occupied space, and is beneficial to installing the absorption refrigeration device 100 in the limited arrangement space of an automobile.

Further, the inlet of the condenser 20 is communicated with the third outlet 23 on the generation port 2, the outlet of the condenser 20 is communicated with the inlet of the evaporator 30, and the outlet of the evaporator 30 is communicated with the third inlet 13 on the absorption port 1.

Specifically, high-temperature refrigerant vapor evaporated in the generation port 2 is discharged from the third outlet 23 and flows to the condenser 20, then the condenser 20 condenses the high-temperature refrigerant vapor into liquid refrigerant and flows to the evaporator 30, then the liquid refrigerant absorbs heat of the passenger compartment 50 and evaporates into low-temperature refrigerant vapor, and finally the low-temperature refrigerant vapor flows back into the absorption port 1 from the third inlet 13.

Furthermore, a liquid absorption core 5 is further arranged in the siphon pipeline 4, and the refrigerant solution in the generation end 2 flows back to the absorption end 1 through the liquid absorption core 5 under the capillary action, so that the refrigerant solution in the generation end 2 is promoted to flow back to the absorption end 1, and the flowing circulation of the refrigerant solution is accelerated.

Specifically, wick 5 is made of a highly hydrophilic wick material, and the micro-surface thereof may form an evaporation film having a large specific surface area to promote heat exchange between the refrigerant solution absorbed through wick 5 and absorption end 1.

Further, the integrated cold source circulation generator 10 further includes a heat exchanger 6; the heat exchanger 6 is disposed outside the bottom of the absorption port 1, and one end of the heat exchanger 6 communicates with the third inlet 13.

Specifically, the low temperature refrigerant vapor formed by evaporation in the evaporator 30 may flow along the heat exchanger 6 toward the absorption port 1, so that the refrigerant solution in the absorption port 1 absorbs the low temperature refrigerant vapor.

Because the absorption process is a heat release process, the heat exchanger 6 is arranged outside the bottom of the absorption end 1, and can realize heat exchange with the absorption end 1, namely when the low-temperature refrigerant vapor formed by evaporation in the evaporator 30 flows to the absorption end 1 along the heat exchanger 6, the low-temperature refrigerant vapor can absorb the heat released in the absorption process, and pre-cool the absorption end 1, so as to promote the continuous operation of the absorption process; at the same time, the temperature difference between the refrigerant vapor and the refrigerant solution entering the absorption end 1 is also increased, so that the absorption process is accelerated.

Referring to fig. 4, the heat exchanger 6 includes a heat exchange tube 61 and a plurality of heat exchange fins 62, and the heat exchange fins 62 are disposed on an outer surface of the heat exchange tube 61.

Specifically, the heat exchange fins 62 are provided on the outer surface of the heat exchange tube 61 to increase the heat transfer area and the radiation heat transfer between the heat exchange fins 62, thereby enhancing the heat exchange efficiency between the heat exchanger 6 and the adsorption port 1.

The heat exchange fins 62 may be at least one of pin fins, rectangular fins, saw-tooth fins, or corrugated fins, that is, the heat exchange fins 62 arranged on the heat exchange tube 61 may be identical or not identical in shape; the heat exchange fins 62 may be uniformly disposed on the heat exchange tube 61, or may be non-uniformly disposed on the heat exchange tube 61. In the present embodiment, the heat exchange fins 62 are corrugated fins uniformly arranged on the outer surface of the heat exchange tube 61.

Further, the heat exchanger 6 is arranged close to the siphon pipe 4, so that heat exchange between the heat exchanger 6 and the siphon pipe 4 is realized.

Specifically, when the refrigerant solution in the generation end 2 has a high temperature after absorbing heat and flows back to the absorption end 1 through the siphon line 4 and/or the wick 5, the low-temperature refrigerant vapor flowing in the heat exchanger 6 can absorb the heat of the refrigerant solution and cool, so as to ensure the temperature difference between the refrigerant solution and the refrigerant vapor in the absorption end 1.

Further, the bottom of the adsorption port 1 is provided with a fourth outlet 14, and the top of the initiation port 2 is provided with a fourth inlet 24. The fourth outlet 14 is communicated with the fourth inlet 24 through the second pipeline 7, and the second pipeline 7 is further provided with a shut-off valve to adjust the on-off state between the fourth outlet 14 and the fourth inlet 24.

Specifically, when the flow of the refrigerant solution between the generation end 2 and the absorption end 1 reaches a balance, the on-off state between the fourth outlet 14 and the fourth inlet 24 can be adjusted by the shutoff valve, so that the concentration difference and the pressure difference of the refrigerant solution between the generation end 2 and the absorption end 1 can be adjusted, and the refrigeration power of the absorption refrigeration device 100 can be adjusted. For example, the communication between the fourth outlet 14 and the fourth inlet 24 is controlled by the shutoff valve, so that part of the refrigerant solution in the absorption end 1 does not participate in the process of absorbing the low-temperature refrigerant vapor, but directly flows to the generation end 2 along the second pipeline 7, the concentration difference of the refrigerant solution between the generation end 2 and the absorption end 1 is adjusted, and more refrigerant solution exists in the generation end 2 for evaporation to form more high-temperature refrigerant vapor, so that the refrigerant flows to the evaporator 30 for heat exchange with the passenger compartment 50 after being cooled by the condenser 20, and the refrigeration power and the refrigeration effect are further improved.

Further, the first pipeline 3 and/or the second pipeline 7 comprises a gravity overflow pipe and a one-way valve 8, so that the refrigerant solution in the absorption end 1 flows to the generation end 2 along the gravity overflow pipe due to the gravity.

Specifically, the check valve 8 is disposed on the gravity overflow pipe, so that the refrigerant solution in the absorption end 1 flows to the generation end 2 in a single direction due to the action of gravity, and when the integrated cold source circulation generator 10 is reversed, the refrigerant solution in the generation end 2 flows back to the absorption end 1 along the gravity overflow pipe.

Furthermore, a heater 9 is arranged outside the bottom of the generation end 2, and the heater 9 can preheat the refrigerant solution in the generation end 2.

Specifically, the heater 9 can preheat the refrigerant solution in the generation end 2, so that the refrigerant solution in the generator can be partially evaporated into high-temperature refrigerant vapor before absorbing the waste heat of the in-vehicle power system 40, the refrigerant solution flowing circulation in the integrated cold source circulation generator 10 is started, the refrigeration rate of the absorption refrigeration device 100 is accelerated, the refrigeration time is shortened, and the refrigeration effect is improved.

Referring to fig. 5, the heater 9 includes a porous heating film 91, and the porous heating film 91 is sintered on the outer wall of the bottom of the generation end 2 by printing. The porous heating film 91 can uniformly heat the refrigerant solution in the generation end 2, and the requirement for reducing the occupied space of the integrated cold source circulation generator 10 can be met due to the small size of the porous heating film 91.

Specifically, the heater 9 further includes a battery management system 93 and a protection resistor 92, the positive electrode and the negative electrode of the porous heating film 91 are respectively connected to the positive electrode and the negative electrode of the battery management system 93, and the protection resistor 92 is further connected between the positive electrode and the negative electrode to prevent the porous heating film 91 from being damaged due to excessive impact current when the circuit is started. The battery management system 93 may be connected to an in-vehicle air conditioner controller, and when the user turns on the in-vehicle air conditioner, the battery management system 93 supplies power to the porous heating film 91 to preheat the refrigerant solution in the generation terminal 2.

Further, the periphery of the integrated cold source circulation generator 10 is further provided with a heat insulation material, such as polytetrafluoroethylene (teflon), etc., which is not limited herein, so as to reduce the influence of the external environment temperature on the integrated cold source circulation generator 10, avoid the heat exchange between the integrated cold source circulation generator 10 and the external environment, and reduce the loss of the refrigeration power.

Further, the absorption refrigeration device 100 further includes a gas-liquid separation pipeline 60, the gas-liquid separation pipeline 60 is disposed at the outer side of the bottom of the integrated cold source circulation generator 10, one end of the gas-liquid separation pipeline 60 is communicated with the in-vehicle power system 40, so that high-temperature hot water and/or high-temperature steam in the power system 40 flows to the bottom of the integrated cold source circulation generator 10 along the gas-liquid separation pipeline 60, at this time, the generation end 2 exchanges heat with the gas-liquid separation pipeline 60, that is, the refrigerant solution in the generation end 2 absorbs heat of the high-temperature hot water and/or the high-temperature steam in the gas-liquid separation pipeline 60, and is evaporated into the high-temperature refrigerant steam. After the heat exchange between the generating end 2 and the gas-liquid separation pipeline 60 is completed, the gas-liquid separation pipeline 60 can also be used for separating high-temperature hot water from high-temperature steam and then discharging the high-temperature hot water.

When the device is used, the porous heating film 91 is started to preheat the refrigerant solution in the generation end 2, so that the refrigerant solution in the generation end 2 is partially evaporated into refrigerant vapor, and the refrigerant solution flowing circulation between the absorption end 1 and the generation end 2 is started; then, the high-temperature hot water and/or high-temperature steam in the power system 40 flows to the bottom of the generation end 2 along the gas-liquid separation pipeline 60, so that the refrigerant solution in the generation end 2 is evaporated into high-temperature refrigerant vapor; the high temperature refrigerant vapor is condensed into a liquid refrigerant after entering the condenser 20; the liquid refrigerant continues to flow to the evaporator 30, the evaporator 30 exchanges heat with the passenger compartment 50, and the liquid refrigerant absorbs heat and evaporates into a low temperature refrigerant vapor; the low temperature refrigerant vapor enters the absorption port 1 along the heat exchanger 6, the heat exchanger 6 can exchange heat with the absorption port 1 to pre-cool the generation port 2 and increase the temperature difference between the refrigerant solution and the refrigerant vapor in the generation port 2, thereby promoting and accelerating the absorption of the refrigerant vapor by the refrigerant solution in the generation port 2; by adjusting the on-off of the second path, the concentration difference and the pressure difference of the refrigerant solution between the generation end 2 and the absorption end 1 can be adjusted, and the refrigeration power of the absorption refrigeration device 100 can be further adjusted.
