A FINLESS HEAT EXCHANGER

摘要

PURPOSE: A finless heat exchanger is provided to enhance the durability of product by eliminating heat radiating fins. CONSTITUTION: A finless heat exchanger comprises a plurality of tubes(11), tanks(12), an intake(31), and an outlet(32). The tubes are formed by connecting a pair of plates(10). Heat exchange medium flows in the tube through an internal flow path(13). The tanks are connected to the flow path and are installed on the upper and the lower of the plates to be able to communicate. The intake and the outlet are formed on an end plate(20) to suck and discharge the heat exchange medium from/to the tube. The tube comprises a refrigerant-side turbulence encouraging part(41) and air-side turbulence encouraging part(42). The refrigerant-side turbulence encouraging part is projected into the flow path. The air-side turbulence encouraging part is projected towards the air flow space between the tubes.
