Title:
FLOW PATH SWITCHING VALVE AND HEAT MEDIUM SYSTEM FOR AUTOMOBILES
Document Type and Number:
WIPO Patent Application WO/2019/176261
Kind Code:
A1
Abstract:
In the present invention, the passage surface area of a thermal protection passage (09D) is set so as to be larger than the passage surface area of a circulation passage (09C) through which cooling water constantly circulates. Since the passage surface area of the thermal protection passage (09D) is set so as to be larger than the passage surface area of a circulation passage (09C) through which the cooling water circulates, the flow rate of the cooling water guided to a radiator (04) by means of the thermal protection passage (09D) increases during the operation of a thermo-element valve (13). As a result, cooling of the cooling water is performed sufficiently by the radiator (04) and overheating can be suppressed as much as possible.
