HEAT EXCHANGER AND MANUFACTURE METHOD THEREOF

摘要

The purpose of the present invention is to maximize a heat transmission performance of a heat exchanger by welding all components forming the heat exchanger, except for insertion spaces wherein thermoelectric modules are inserted, using an identical base material to remove the thermal resistance of a heat transmission passage. The heat exchanger is capable of being easily manufactured through a simple manufacturing process, and prevents damage to the thermoelectric modules in the manufacturing process. The heat exchanger comprises: a three-layered tube (7); the thermoelectric modules (3) inserted into the insertion spaces; cooling pins (9) joined to an outer surface of the three-layered tube (7); an upper tank (11); and a lower tank (13).
