Background

With the increasing tidiness and beauty of urban buildings, shutters are designed on the periphery of air conditioner mounting machines in residential areas where people live, when the air conditioner outdoor units are mounted in machine positions, part of high-temperature hot air generated after heat exchange of the outdoor units in hot summer is shielded by the shutters, and in addition, heating of electric control devices during working is caused, so that the service lives of some electric control devices are shortened or the electric control devices fail to realize refrigeration work;

at present, two heat dissipation modes for the variable frequency air conditioner exist in the industry, the first mode is that a power device is installed on an aluminum fin in the prior art and is dissipated by an outdoor fan, the other mode is that the power device is installed on an aluminum plate, and the aluminum plate presses a U-shaped groove and a U-shaped copper pipe to dissipate heat through a refrigerant; the cooling effect of the U-shaped pipe is reduced by 16 ℃ compared with the traditional air cooling, but the cooling radiation area is small, the electric control core devices such as IPM and IGBT devices can only be cooled, and a part of devices are still cooled by the traditional air cooling, and when the outdoor environment temperature is high, the unsmooth air outlet of the outdoor fan can cause the damage of a part of electric control devices.

Disclosure of Invention

Aiming at the problems, the invention provides a heat dissipation device for an electric control device of a variable frequency air conditioner, which effectively solves the problems pointed out in the background technology.

The technical scheme adopted by the invention is as follows:

the utility model provides a frequency conversion air conditioner automatically controlled device heat abstractor, includes the off-premises station body, the inside in off-premises station body is equipped with fan storehouse and compressor storehouse, fan storehouse and compressor storehouse separate through the baffle, the baffle is fixed with automatically controlled drive plate in one side in compressor storehouse, is fixed with heat abstractor in one side in fan storehouse, heat abstractor has seted up perpendicular baffle in the top of baffle, and the first louvre that is linked together with the compressor storehouse, heat abstractor is equipped with the second louvre in the fan storehouse, first louvre and second louvre be linked together, the off-premises station body is seted up the air intake in the rear side in compressor storehouse.

Preferably, the second heat dissipation hole is perpendicular to the first heat dissipation hole.

Preferably, the second heat dissipation holes are located at the front side and the rear side of the heat dissipation device.

The perpendicular design of second louvre and first louvre can prevent that the fan in the fan storehouse from bringing the rainwater into the compressor storehouse, avoids automatically controlled drive plate to be soaked by the rainwater.

Preferably, the aperture of the second heat dissipation hole is 3-5 mm.

The aperture of the second heat dissipation hole is set to be 3-5mm, so that insects can be prevented from entering the compressor bin, and the normal operation of the electric control drive plate is guaranteed.

Preferably, the air inlet is provided with a filter screen.

Through the design of filter screen, can prevent that the worm from in the air intake gets into the compressor storehouse, guarantee the normal operating of automatically controlled drive plate.

According to the invention, the air inlet is formed in the rear side of the outdoor unit body, outdoor fresh air enters the compressor bin from the air inlet to dissipate heat of the electric control driving plate and enters the fan bin through the heat dissipation device in the running process of the fan, and finally is discharged out of the outdoor unit body by the fan, so that a good heat dissipation effect is achieved.

FIG. 1 is a schematic structural diagram of the present invention.

Detailed Description

The invention is described in further detail below with reference to specific embodiments and with reference to the attached drawings.

Example 1

As shown in fig. 1, a heat dissipation device of an electric control device of a variable frequency air conditioner comprises an outdoor unit body 1, a fan chamber 2 and a compressor chamber 3 are arranged inside the outdoor unit body 1, the fan bin 2 and the compressor bin 3 are separated by a partition plate 4, an electric control driving plate 5 is fixed on one side of the compressor bin 3 by the partition plate 4, the electric control driving plate 5 is positioned on the top of the partition plate 4, a heat dissipation device 6 is fixed at one side of the fan bin 2, a first heat dissipation hole 7 which is vertical to the partition plate 4 and is communicated with the compressor bin 3 is arranged above the partition plate 4 of the heat dissipation device 6, the heat dissipation device 6 is provided with a second heat dissipation hole 8 in the fan chamber 2, the first heat dissipation hole 7 is communicated with the second heat dissipation hole 8, the outdoor unit body 1 is provided with an air inlet 9 at the rear side of the compressor bin 3, and the air inlet 9 is positioned at the bottom of the compressor bin 3.

The second heat dissipation hole 8 is vertical to the first heat dissipation hole 7.

The second heat dissipation holes 8 are located at the front and rear sides of the heat dissipation device 6.

The aperture of the second heat dissipation hole 8 is 3-5 mm.

The air inlet 9 is provided with a filter screen.

The working principle of the invention is as follows:

outdoor unit body 1 is when the operation, and the new trend is followed air intake 9 and is got into in the compressor storehouse 3, and by lower up flow in compressor storehouse 3, dispel the heat to automatically controlled drive plate 5 when automatically controlled drive plate 5 to through first louvre 7, second louvre 8 after, rely on the fan to discharge outside outdoor unit body 1, just so accomplished the heat dissipation to automatically controlled drive plate 5, and the addition of new trend can promote the radiating effect greatly.

Finally, it should be noted that the above-mentioned list is only the specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the invention.
