A plate type heat exchanger consists of a plurality of heat transmission plates which are piled up and secured to each other. Side wall members are interposed between the adjacent heat transmission plates, so that multiple stages of spaces are formed in the heat exchanger. Additionally, separator wall members are interposed between the adjacent heat transmission plates in such a manner that two fluid paths are defined in alternate stages of the spaces. The side wall members and the separator members are formed of rod material, thereby rendering the heat exchanger light in weight while lowering the production cost of the heat exchanger.

A plate type heat exchanger for first and second fluids, comprising: a first heat transmission plate made of a sheet metal, including a first rectangular and flat plate section having first and second longer opposite sides, and first and second shorter opposite sides, said first plate section being formed with first and second openings located in the vicinity of said first shorter side, and third and fourth openings located in the vicinity of said second shorter side, and first and second vertical wall sections integrally connected to said first plate section respectively at said first and second longer sides, and being generally vertical relative to said first plate section, a second heat transmission plate made of a sheet metal, disposed in spaced parallel relation to said first heat transmission plate and located above said first heat transmission plate, said second heat transmission plate including a second rectangular and flat plate section having third and fourth longer opposite sides, and third and fourth shorter opposite sides, said second plate section being formed with fifth and sixth openings located in the vicinity of said third shorter side, and seventh and eighth openings located in the vicinity of said fourth shorter side, and third and fourth vertical wall sections integrally connected to said second plate section respectively at said third and fourth longer sides, and being generally vertical relative to said second plate section; first and second side wall members made of metal, interposed between said first and second plate sections to define a space, said first side wall member being located in the vicinity of said first and third shorter sides, said second side wall member being located in the vicinity of said second and fourth shorter sides, each of said first and second side wall members being formed of a rod material; first and second separator wall members made of metal, interposed between said first and second plate sections to divide said space into a first fluid flow passage through which a first fluid flows from said first opening to said fourth opening, a second fluid flow passage through which the second fluid flows from said second opening to said sixth opening, and a third fluid passage through which the second fluid flows from said third opening to said seventh opening, said second and third flow passages being communicated with each other, each of said first and second separator wall members being formed of a rod material; a corrugated plate made of metal, disposed in said first flow passage and between said first and second plate sections; and means for fixedly connecting said side wall members and said separator wall members, and said corrugated member to said first and second heat transmission plates under brazing; wherein said side wall member and said separator wall member are the same in height and smaller in height than said vertical wall sections of said heat transmission plates; wherein each of said first heat transmission plate vertical wall sections is slightly inclined relative to said plate section so that an angle slightly larger than right angles is formed between the vertical wall section and the plate section; wherein each of said second heat transmission plate vertical wall sections is slightly inclined relative to said plate section so that an angle slightly larger than right angles is formed between the vertical wall section and the plate section; wherein each of said first and second vertical wall sections extends downwardly from said first plate section; wherein each of said third and fourth vertical wall sections extends from said second plate section in the same direction as said first and second vertical wall section, said third and fourth vertical wall sections being contactable with said first and second vertical wall sections; wherein each of said first and second side wall members includes a first straight section located along the shorter side, a second straight section integral with said first straight section and located along the longer side, and a third straight section integral with said first straight section and located along the longer side; wherein said first separator wall member is so located as to surround, in cooperation with said first side wall member, said second and sixth openings, and said second separator wall member is so located as to surround, in cooperation with said second side wall member, said third and seventh openings; wherein said first and third openings are positioned on the opposite side of said second and fourth openings with respect to a longitudinal center axis of said first heat transmission plate; wherein said fifth and seventh openings are positioned on the opposite side of said sixth and eighth openings with respect to a longitudinal center axis of said second heat transmission plate; wherein said first separator wall member includes a first section located near the periphery of said second opening, a second straight section integral with said first section and located along the second longer side of said first plate section, and a third straight section integral with said first section and located along the first shorter side, said third section contacting said first side wall member first section; wherein said second separator wall member includes a first section located near the periphery of said third opening, a second straight section integral with said first section and located along said first longer side of said first plate section, and a third straight section integral with said first section and located along the second shorter side, said third section contacting said second side wall member first section.
