Tube-in-tube evaporative condenser with fins

Abstract

The invention provides a tube-in-tube evaporative condenser with fins. The tube-in-tube evaporator condenser comprises a heat exchange casing composed of inner-layer tubes and outer-layer tubes arranged outside the inner-layer tubes in a sleeving manner. First channels are formed in the inner-layer tubes. Second channels are formed between the inner-layer tubes and the outer-layer tubes. The tube-in-tube evaporative condenser with the fins is characterized by further comprising the multiple radiating fins arranged in parallel and provided with multiple rows and columns of expansion connecting holes, a cooling water inlet collecting tube, a cooling water outlet collecting tube, a cooling water inlet tube on the cooling water inlet collecting tube, a cooling water outlet tube on the cooling water outlet collecting tube, a refrigerant gas collecting tube, a fluid collecting tube, a refrigerant inlet tube on the refrigerant gas collecting tube and a refrigerant outlet tube on the fluid collecting tube. The multiple radiating fins form a fin row. The heat exchange casing perpendicularly penetrates the fin row through the expansion connecting holes to be in perpendicular expansion connection with the radiating fins. The cooling water inlet collecting tube and the cooling water outlet collecting tube are connected with the multiple inner-layer tubes, and the refrigerant gas collecting tube and the fluid collecting tube are connected with the two ends of the multiple second channels respectively. According to the technical scheme, the heat exchange area is enlarged, heat resistance is reduced, and the problem of low radiating efficiency in the prior art is solved.

Description

technical field [0001] The invention relates to an evaporative condenser, in particular to a casing evaporative condenser with fins, and belongs to the field of HVAC. The invention relates to an evaporative condenser, in particular to a casing evaporative condenser with fins A condenser, the invention belongs to the field of HVAC. Background technique [0002] In the industry, evaporative condensing air-conditioning equipment has the characteristics of energy saving, water saving, good cooling effect, compact structure, easy installation and maintenance, and low operating costs. It can save energy by more than 35%. Compared with the water-cooled air-conditioning system, it can save energy by more than 15%. The cooling water temperature is close to the wet bulb temperature, which saves a lot of cooling water energy consumption, realizes the high cooling efficiency of water-cooled chillers and the advantages of no cooling water system for air-cooled chillers; the current disa...
