摘要： A plate type heat exchanger having heat exchange plates wherein in order to increase the support strength of the packing groove periphery to prevent flexure while providing reliable sealing, the lateral wall defining the peripheral edge of a packing groove is shaped in such a manner that its upper surface is capable of abutting against the bottom surfaces of distributing grooves while in a double seal region the width of a liquid passage groove in a plate having no packing mounted therein is smaller than that of a packing groove in a plate having a packing mounted therein, so that the bottom surface of the liquid passage groove and the upper surface of the lateral wall abut against the upper surface of the packing and bottom surface of the packing groove.
