Description

Heat radiation structure of evaporative condenser

Technical Field

The utility model belongs to the technical field of evaporative condensers, and particularly relates to a heat dissipation structure of an evaporative condenser.

Background

The evaporative condenser is a heat exchange device for cooling a refrigerator, and is formed by combining components such as a fan, a condensing coil, heat exchange plates, a box body and the like. The working principle is that when the evaporator works, the overheated high-pressure refrigerant gas discharged by the compressor in the refrigerating system enters from the upper part of the coiled pipe, the water spraying device sprays water on the outer wall of the coiled pipe to quickly evaporate water on the pipe, and the heat released by the condensation of the overheated high-pressure refrigerant gas discharged by the compressor in the refrigerating system in the pipe is taken away by the evaporated water and flowing air because of the strong ventilation of the fan, and the gas in the pipe is condensed to become liquid and flows out from the lower part. The water spraying device is provided with a water blocking grid which blocks water drops carried out by air, so that unvaporized spray water falls into a pool below. The float valve in the pool can adjust the water supplementing quantity to keep the water supplementing quantity at a certain water level.

The spray pipes of the general evaporative condenser spray from top to bottom, and because the arrangement of the coiled pipes or the finned pipes is dense, the area of cooling water contacting the spray is small, and the heat dissipation efficiency of refrigerant gas is poor, so that the heat dissipation structure of the evaporative condenser needs to be increased, the contact area of the cooling water and the condensing pipes is increased, and the condensation efficiency of the evaporative condenser is improved.

For the problems in the related art, no effective solution has been proposed at present.
