Claims

[Scope of utility model registration request]

A plurality of plates having a heat transfer surface and passage holes at the four corners are stacked, and a first and a second plate are placed between each plate.
In order to construct a plate heat exchanger in which flow paths are alternately formed, in the gasket interposed between each plate, the gasket is used for the heat transfer surface of the plate and the two passages communicating therewith. A first gasket part that integrally surrounds the hole, and a second gasket part that surrounds the remaining two passage holes and are formed separately from a material different from the first gasket part. A plate type gasket comprising: a display portion for displaying the material of which each gasket is formed, at a portion of the first and second gasket portions that serves as a connecting portion that does not come into contact with the heat exchange medium; Heat exchanger gasket.
