Description

Technical Field

[0001] The utility model belongs to the technical field of fin-tube heat exchangers, and particularly relates to a fin-tube heat exchanger with a condensed water receiving structure. Background Art

[0002] Fin-tube heat exchanger is a highly efficient heat transfer equipment, widely used in various industrial fields, such as HVAC (heating, ventilation and air conditioning), chemical industry, electricity, refrigeration, etc. This heat exchanger increases the heat transfer area by adding fins to the outer surface of the tube, thereby improving the heat exchange efficiency. Fin-tube heat exchangers will produce condensed water during the heat exchange process, and some fin-tube heat exchangers will set corresponding dust plates at the air inlet of the fin-tube heat exchanger in order to reduce the blockage caused by dust. The setting of the dust plate will cause the inner side to be unable to conveniently guide the condensed water when it is generated. There may be a situation where the condensed water flows to the outside through the groove, which will cause the outside of the fin-tube heat exchanger to be humid, affecting the specific use of the fin-tube heat exchanger, and will have an impact on the use of the surrounding environment and related equipment. In addition, when receiving and concentrating the condensed water, the condensed water may not be discharged in time due to the blockage of debris, resulting in overflow, which will also affect the surroundings of the fin-tube heat exchanger.
