Background

The cooling tower is a device which uses water as circulating coolant, absorbs heat from a system and discharges the heat to the atmosphere so as to reduce the water temperature; the cold is an evaporation and heat dissipation device which generates steam by utilizing the heat exchange between water and air after flowing and contacting, the steam volatilizes and takes away heat to achieve the principles of evaporation and heat dissipation, convection heat transfer, radiation heat transfer and the like to dissipate waste heat generated in industry or refrigeration air conditioners to reduce the water temperature, the device is generally barrel-shaped, so the device is named as a cooling tower, a reverse flow closed cooling tower, a circulating system which can avoid water quality pollution caused by the direct contact of external circulating water and air is an automatic frequency conversion control system, and the electric power and the hydraulic power are saved to a great extent.

The circulating water system is divided into an internal circulating water system: circulating water heats up through heat source heat transfer and gets into heat exchanger, sends the heat into the external world through the heat exchanger pipe, and the circulating water after the cooling is sent to the heat source by system's circulating water pump, outer circulating water system: the spray water is delivered to the upper water distribution pipeline from the lower water tank by the water dispersion pump, the water is sprayed out and then contacts with the heat exchanger pipe, part of the water is evaporated and then carries heat out, the cooled spray water falls into the lower water tank for recirculation, and the internal circulating water exchanges heat through the heat exchanger pipe, so that the water quality pollution caused by direct contact of the external circulating water and air is avoided.

But it is when the in-service use, still have some shortcomings, like the current adverse current closed cooling tower in the market, the ventilating fan at device top when using, have dust or impurity entering cooling tower inside, make the device break down easily when using, cause the device to damage, make the cooling effect of device reduce, the availability factor of device has been reduced, simultaneously when the device is cooled down to the coil pipe through the cooling shower nozzle, the speed of effectual control rivers, make the water in the water catch bowl can not effectual cooling behind the inflow water tank, the cooling efficiency of device has been reduced, the result of use of device has been reduced.

It is therefore desirable to provide a low energy consumption counter-flow closed cooling tower.
