PRINTED CIRCUIT HEAT EXCHANGER AND METHOD FOR MAKING THE SAME

摘要

PURPOSE: A printed board type heat exchanger and a manufacturing method thereof are provided to minimize wrong arrangement between channels by closely combining a head unit with a side of a plate. CONSTITUTION: A printed board type heat exchanger includes a plate (110), a header unit (120), and a fixing pin (130). A plurality of plates are prepared and laminated and a channel for a fluid is formed and includes an arrangement protrusion (112). The header unit is installed in the plates. The fixing pin arranges and fixes the arrangement protrusion to prevent wrong arrangement when the plates are being laminated. The arrangement protrusion is protruding from a dent area. The fixing pin is prepared along a thickness direction of the plates and elastically fixed with the arrangement protrusion in order to be completely included in the dent area.
