PLATE HEAT EXCHANGERS HAVING COPPER CONNECTORS'S MANUFACTURING METHOD

摘要

The present invention relates to a plate type heat exchanger including a copper connector and, more specifically, to a plate type heat exchanger including a copper connector and a manufacturing method for the same, wherein an existing stainless steel connector of the plate type heat exchanger is replaced to a copper connector to improve welding performance with a cooper connection pipe to be connected to the heat exchanger. The manufacturing method for the same includes: a step (S11) of inserting and laminating a brass solder plate between upper and lower plates and a heat exchange plate (2) and forming an assembly; a step (S12) of inserting the copper connector into a port hole with a brass solder ring at the same time or in order; and a step (S13) of brazing the assembly and the connector at the temperature of 980-1050C at the same time after inserting the assembly in which the connector is assembled into a vacuum brazing furnace.
