When the water-vapor heat exchanger runs, the spray pump pumps water from the water tank at the bottom of the cooler to the spray pipe, the water is sprayed on the surface of the light pipe to form a water film, the heat in the pipe is absorbed, water vapor is evaporated to the air which passes through the water film, the heat is transferred to the air, the spray water falls into the water tank at the bottom and is pumped to the spray pipe, and the process is repeated in a circulating way. Under the suction action of the top fan, ambient air enters from the louver at the lower part of the cooler, absorbs water vapor evaporated by the water film on the surface of the light pipe, carries latent heat of water away, and indirectly carries away heat of a medium in the pipe.
The problem that it exists is that when compound cooler was used in summer, the hot medium often can not cool the low temperature that the user required, and top fan and its speed reducer often because of being surrounded by the hot air that discharges and summer sun exposure lubrication failure, and then break down.
