Abstract:
Gaskets for forming a flow passage are interposed at an outer periphery between heat transfer plates stacked in plurality, and gaskets for forming a communication passage which alternately surround a passage hole of the heat transfer plate that is adjacent are interposed. A first flow passage through which a high-temperature fluid is circulated with the heat transfer plate being a boundary, a second flow passage through which a low-temperature fluid is circulated, and the communication passage for inputting and outputting the fluid to and from the first flow passage and the second passage are formed alternately. A drain hole is formed at the heat transfer plate to drain the fluid leaking from the first flow passage and the second flow passage or the communication passage. The drain hole is surrounded by a gasket isolated from the first flow passage and the second flow passage or the communication passage.
A leak fluid passage or a leak fluid collection part is formed by the gasket.
