Title:
PLATE HEAT EXCHANGER, HEAT PUMP SYSTEM, AND HEAT TRANSFER PLATE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/229934
Kind Code:
A1
Abstract:
A plate heat exchanger (1) comprises a fluid reservoir (70) that is formed in an annular shape as viewed from the direction in which a first transfer exchanger plate (30) is stacked, so as to be protruded in the direction in which the first heat transfer plate (30) is stacked, on the outer periphery of a first sealing portion (60). The first heat exchanger plate (30) is a double-walled structure with plate (30a) and plate (30b) stacked, the end of the plate (30b) being extended inside the fluid reservoir (70). The end of the plate (30b) is formed with a leading end facing the protruding portion of one of the plates, and the fluid leaking into the fluid reservoir (70) is released outside through the gap between the plate (30a) and the plate (30b).
