PIN-TUBE TYPE HEAT EXCHANGER AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a method for manufacturing a heat exchanger, and more particularly, to a method for manufacturing a pin-tube type heat exchanger in which a thin plate is punched to form vertical tubes, and the vertical tubes are attached with molten metal, to simplify work and improve evaporator efficiency. For this, the method for manufacturing a pin-tube type heat exchanger includes the steps of forming a plurality of cylindrical vertical tubes on a thin plate by punching holes in the thin plate, stacking the thin plates such that the vertical tubes are passed through to one another respectively, and attaching ends of the vertical tubes to the thin plate in contact with the ends, respectively.
