Document Type and Number:

WIPO Patent Application WO/2013/061966

Kind Code:

A1

Abstract:

In the present invention, a plurality of heat transfer plates are stacked, said heat transfer plates having a plurality of through holes formed therein. Flow-path forming gaskets are interposed between the outer peripheral sections of the adjacent heat transfer plates, whereby the heat transfer plates are used as boundaries to alternately form first flow paths for circulating high-temperature fluid, second flow paths for circulating low-temperature fluid, and connecting paths for the inflow and outflow of fluid to and from the first flow paths and second flow paths. Connection-path forming gaskets which surround the through holes are interposed between adjacent heat transfer plates, whereby connection paths for the inflow and outflow of fluid to and from the first flow paths and connection paths for the inflow and outflow of fluid to and from the second flow paths are formed. The connection-path forming gaskets are formed having inner gasket members that surround the through holes and, overlapping the inner gasket members, outer gasket members that surround the inner gasket members.
