Patent ID: 7516781

Claim:
A plate-like heat exchanger in which a fluid flows, the plate-like heat exchanger comprising: a plate-like structure; a plurality of flow paths respectively including opened ends, the flow paths being formed in an interior of the plate-like structure and running in a first direction; a plurality of covering members, each of the covering members having one or more grooves, the covering members being fixed to the plate-like structure, at least one end of the covering members extending to reach any one or more peripheries of the plate-like structure; a plurality of crossing flow paths defined by the grooves of the covering members and the plate-like structure, the crossing flow paths being directed to a second direction intersecting the first direction and respectively being linked with the opened ends of the flow paths so as to distribute the fluid to the flow paths to direct a plurality of parallel bidirectional flows respectively flowing in the flow paths; and inflow and outflow ports respectively for inflow and outflow of the fluid, the ports respectively being formed at the ends of the covering members at the peripheries of the plate-like structure and linked with the crossing flow paths, wherein the plate-like structure comprises three plate bodies accumulated with each other and the flow paths are formed between the plate bodies.
