Document Type and Number:
WIPO Patent Application WO/2017/122893
Kind Code:
A1
Abstract:
The present invention relates to a plate-type heat exchanger having a copper connector and, more specifically, to a plate-type heat exchanger having a copper connector and a method for manufacturing the same, the plate-type heat exchanger replacing a conventional stainless steel material of a connector of a plate-type heat exchanger with a copper material in order to increase weldability with a connection pipe, which is made from the copper material, for connecting with the heat exchanger. To this end, the method comprises the steps of: (S11) inserting brass solder plates between upper and lower plates and heating plates (2), and then stacking the same so as to form an assembly; (S12) inserting, into port holes, the copper connectors together with brass solder rings or one by one; and (S13) charging a vacuum brazing furnace with the assembly having the connectors inserted therein, and then simultaneously brazing the assembly and the connectors at 980-1,050°C.
