Heat exchanger

A heat exchanger comprising:

• a corrugated plate;
• a base plate joined on one of surfaces of said corrugated plate;
• a cover plate joined on other surface of said corrugated plate;
• two types of fluid flow paths A and B defined by said corrugated plate, said base plate, and said cover plate along a longitudinal direction of said corrugated plate, said two types of fluid flow paths comprising a plurality of flow paths A defined by said one of surfaces of said corrugated plate and said base plate, and said plurality of flow paths B defined by other surface of said corrugated plate and said cover plate, said plurality of flow paths A and said plurality of flow paths B being formed separately from each other;
• one of upper end portions and lower end portions of said corrugated plate for forming the flow paths A, which are hermetically sealed by providing two corresponding slant surfaces, and other one of the upper end portions and lower end portions of said corrugated plate for forming the flow paths B, which are hermetically sealed by providing two corresponding slant surfaces;
• inlet ports for said fluid B being provided on one end portion of the corrugated plate which is the hermetically sealed side of the flow paths A, and inlet ports for said fluid A being provided on other end portion of the corrugated plate which is the hermetically sealed side of the flow paths B;
• outlet ports for said fluid A and for said fluid B respectively being provided on opposite sides of said inlet ports for fluid A and fluid B,
• wherein heat is exchanged between fluid A and fluid B via the corrugated plate by supplying fluid A into the plurality of said flow paths A and supplying fluid B into the plurality of said flow paths B respectively from said inlet ports toward said outlet ports.

• upper end portion and lower end portion of said corrugated plate forming the flow paths A or B, which are hermetically sealed by providing two corresponding slant surfaces;
• inlet ports provided on said base plate or said cover plate forming said flow paths A or said flow paths B, upper end portions and lower end portions of which are hermetically sealed, and outlet ports provided opposite side of said inlet ports;
• inlet ports provided on one end of said flow paths A or said flow paths B, upper end portions and lower end portions of which are not hermetically sealed, and outlet ports provided on opposite side of said inlet ports,
• wherein heat is exchanged between fluid A and fluid B via the corrugated plate by supplying fluid A into the plurality of said flow paths A and supplying fluid B into the plurality of said flow paths B respectively from said inlet ports thus constructed toward said outlet ports.
