わせると云う効果を有している。BACKGROUND ART In this type of plate heat exchanger, the heat transfer plate generally has an opening 1, as shown in FIG.
A plate A is inserted with a gasket 5a, surrounding the openings 3 and 4 so as to communicate with each other, and closing the other openings 1 and 2. There are two types of plates B, each of which has a gasket 5a inserted therein, and a plurality of plates A and B are alternately superimposed so that heat exchange fluids of different types are transferred to one plate A or B in the gap between the plates. A plate heat exchanger is constructed by forming a fluid flow path or a heat exchange chamber that circulates through the plate. In a heat exchanger with such a configuration, in plate A, fluid flows in from opening 1, passes through the heat transfer surface, flows from opening 2 to opening 2 of plate B, and further flows to the back side of plate B. It merges with the fluid traveling through the heat transfer surface of another plate A, which polymerizes into
It is discharged. In plate B, another fluid enters through the openings 3 and exits through the openings 4 through the heat transfer surface. Then, on the heat transfer surface of the plates A and B, which are alternately laminated and laminated,
Heat exchange between the two fluids takes place. By the way, in the plates A and B, the plate heat transfer surfaces are formed by press molding, for example, in the form of corrugations 6 consisting of alternating arrays of weir portions 7 and groove portions 8 each having a trapezoidal cross section. This waveform 6 improves the heat exchange efficiency, and when plates A and B are superposed, the dam part 7 of plate A
This has the effect that the grooves 8 of plate B and the grooves 8 of plate B intersect and abut, and at the same time, the grooves 8 of plate A and the dam 7 of plate B cross and abut each other, supporting the adjacent plates. There is.

度が低下すると云う欠点を有していた。Problems to be Solved by the Invention In the plate heat exchanger described above, the fluid flowing in from the opening 1 of the plate A has a groove 8 on the heat transfer surface of the adjacent plate B with respect to the flow direction of the fluid. Since they intersect and create resistance, they tend to flow mainly along the grooves 8 of the plate A toward the openings 2. Therefore, in the plate heat exchanger described above, attempts are made to reduce pressure loss. For example, it is necessary to widen the width of the groove portion 8 to enlarge the flow path, but on the other hand, there is a drawback that the bending strength of the groove bottom in the direction perpendicular to the waveform 6 is reduced.

る。Means to Solve the Problem This invention has openings at the four corners of the heat transfer surface, and allows the two fluids to be heat exchanged to flow from the inflow opening at one corner diagonally to the outflow opening at the other corner on both sides of the heat transfer surface. Weir parts parallel to each other and groove parts wider than the weir parts are formed on the heat transfer surface in an alternating arrangement along the flow direction of each fluid to achieve wave-like transmission. Two types of heat transfer plates that serve as hot surfaces are combined with their wavy heat transfer surfaces in contact with each other, and multiple sets of these are stacked, and two fluids for heat exchange are formed between each layer. In a plate type heat exchanger in which heat is exchanged via the heat transfer plates by alternately flowing through the channels, the bottom surface of each groove formed on the heat transfer surface of each heat transfer plate has a surrounding area. Reinforcing convex portions that are raised and depressed inside are formed at appropriate intervals and low along each groove portion.

抗を高めることはない。Effect The heat exchange fluid flows through the wide groove, reducing pressure loss. Furthermore, the reinforcing convex portions prevent a decrease in bending strength in the direction perpendicular to the waveforms due to the wide groove portions of the heat transfer plate. Of course, since the reinforcing convex portion is formed low, it does not increase the flow path resistance.
