The evaporative condenser is a main heat exchange device in a refrigeration system, and the action principle of the evaporative condenser is as follows: the superheated high-pressure refrigerant gas discharged from the compressor in the refrigeration system passes through the condensing exhaust pipe in the evaporative condenser, so that the high-temperature gaseous refrigerant exchanges heat with the spray water and air outside the exhaust pipe. Namely, the gaseous refrigerant is gradually condensed into the liquid refrigerant from top to bottom after entering the discharging pipe from the upper opening. The super strong wind force of the matched induced draft fan enables the spray water to completely and uniformly cover the surface of the coil pipe, and the heat exchange effect is greatly improved by the aid of the wind force of the water.

In the production and manufacturing process of the novel evaporative plate-tube condenser, the assembly must be separately pressed for leakage detection, and the sealing performance of the assembly is ensured. The novel evaporative plate-tube condenser uses a phi 8mm steel tube due to design requirements, and the leakage detection operation of the pipeline is generally carried out mainly through a water injection mode, namely liquid water with certain pressure is injected into the pipeline, however, the mode causes water stain in the pipeline after detection, rust easily appears in the pipeline after a period of time, and therefore the sale of the pipeline is greatly influenced.
