Combined heat exchanger

Abstract

The invention relates to a heat exchanger, in particular to a combined heat exchanger. The combined heat exchanger comprises air cooling-type heat exchangers, a spray cooling-type heat exchanger and a shell; the air cooling-type heat exchangers and the spray cooling-type heat exchanger are located in the shell; the number of the air cooling-type heat exchangers is two, and the two air cooling-type heat exchangers are arranged in a V shape; the spray cooling-type heat exchanger is located below the two air cooling-type heat exchangers; the lower sides of the two air cooling-type heat exchangers are respectively connected with a primary side liquid separator; each primary side liquid separator connected with the corresponding air cooling-type heat exchanger is connected onto the spray cooling-type heat exchanger through a spray cooling-type manifold; the upper surface of the spray cooling-type heat exchanger is provided with spray pipes arranged at a certain distance. According to the combined heat exchanger disclosed by the invention, the heat exchange efficiency is greatly increased; on the condition that the cost is not increased, the condensing temperature of refrigerating fluid is reduced, so that the input power is reduced, and the goals of energy saving and emission reduction are directly achieved.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a combined heat exchanger. Background technique [0002] As a necessity for creating and improving production and living environment, air conditioning plays an important role in cold winter and hot summer. The work of the air conditioner is inseparable from the heat exchanger, which is very important in the whole air conditioner. [0003] At present, quite a few of them use non-water-cooled cooling heat exchangers, and the traditional non-water-cooled cooling heat exchangers are air-cooled heat exchangers. However, when this kind of heat exchanger is cooling in summer, the condensation temperature of the condensation is very high, and the condensation temperature of the refrigerant is often about 15°C higher than the temperature of the cooling medium (air), which directly leads to the transfer of the air-cooled heat exchanger. The thermal efficiency is reduced, and the cooling effect is not ...
