STRUCTURE OF A PLATE HEAT EXCHANGER WHICH IS HEAT-EXCHANGED WITH CROSSING HEATED FLUID AND HEATING FLUID

摘要

PURPOSE: A structure of a plate heat exchanger is provided to improve heat exchange efficiency and simplify the structure of a pipe interlinking heat exchangers.;CONSTITUTION: A structure of a plate heat exchanger comprises an A type heat exchange plate(12a) which includes a heating flow path(13a), a B type heat exchange plate(12b) which includes a heated flow path(13b), and a cover(18) which is attached in both side of the heat exchange plates wherein the A type heat exchange plate and the B type heat exchange plate are laminated. Heating flow holes(20a,20b) are formed along a straight line connecting center parts of the heat exchange plates. Heating ports(22a,22b) communicated with the heating flow holes are attached on the cover. Heated flow holes(30a,30b) connected through the heated flow path are formed in the corner of the heat exchange plates and is crossed around the heating flow holes. The heated ports(32a,32b) communicated with the heating flow holes are attached on the cover.;COPYRIGHT KIPO 2010
