Claims

[Scope of Claim for Utility Model Registration] (1) An outer tube and an inner tube each having a coolant circulation system line or a coolant circulation system line connected to the other end thereof are arranged substantially concentrically, and the outer tube One end and one end of the inner tube are made to communicate with each other to form the medium to be cooled or a flow path for the coolant, and the coolant or medium to be cooled is introduced into the flow path on the outer peripheral side partitioned by the outer tube and the inner tube. Forming a heat exchange section through which the heat exchange section passes, and further forming a pressure feeding section in which a circulation device for the medium to be cooled or for the cooling medium is disposed in a flow path in the inner pipe inside the heat exchange section. A cooling device characterized by: (2) One end of the outer pipe is connected to one end of a pipe whose other end is connected to a cooled medium circulation system line or a cooling strategy circulation system line to form a flow path for the cooled medium or cooling medium. , disposing a circulation device for the medium to be cooled or a cooling medium in the flow path in the pipe, and at a position upstream of the circulation device in the flow path in the pipe,
A valve is provided that opens only when the circulation equipment is in operation to allow communication between the outer circumferential flow path partitioned by the outer pipe and the inner pipe and the flow path in the pipe, and Claim: A valve is provided at an upstream position of the circulation device, which opens only when the circulation device of the pressure feeding section is in operation, and allows communication between the flow path on the outer peripheral side partitioned by the outer tube and the inner tube and the flow path in the inner tube. 1) Cooling device as described.
