Indirect evaporation type cooling/condensing device

Abstract

An indirect evaporating cooling / condensing device comprises a blower, a shell body, a spraying machine, a dividing wall type heat exchanger, a wind inlet, a water pump and a water collecting plate, and an air-water heat exchanger which is arranged on the wind inlet. The water pump pumps water from the water collecting plate and sends to the water channel of the air-water heart exchanger, cools the environmental air inducted from the wind inlet enters the spraying machine after being cooled; the water which flows out from the spraying machine is sprayed on the outer surface of the dividing wall type heat exchanger, the water flows back to the water collecting plate depending on the gravity; and the cooled medium which enters into the dividing wall type heat exchanger from the entrance is cooled by the water sprayed from the spraying machine and then flow out from the cooled medium exit. The invention not only can be used as the enclosed type cooling tower, but also can be used as the evaporating type condenser; and compared with the prior art, the utility model can make the temperature of the out flowing liquid of the liquid with single-phase much lower in winter, and also can reduce the condensing temperature of the refrigerating and the chemical liquid system; the utility model has cooling / condensing function for the whole year and is useful for the energy saving running of air-conditions, refrigerating and chemical systems.

Description

technical field

[0001] The invention relates to a fluid cooling / condensing device adopting an indirect evaporation method, which belongs to the fields of refrigeration, air conditioning and chemical industry, and is especially suitable for evaporative condensers and closed cooling towers. Background technique

[0002] Cooling tower is a common cooling equipment in refrigeration, air conditioning and chemical industry. It can cool the high-temperature cooling water discharged from the refrigerator to produce cooling water slightly higher than the wet bulb temperature of the air. However, due to direct contact with the outside world, the conventional open cooling tower During the long-term operation of the system, problems such as water quality deterioration, salt concentration, and large floating water are prone to occur, which will have a certain impact on the life and efficiency of the refrigeration unit. At the same time, it is difficult to provide zero-cost chilled water (...
