Claims

[Scope of utility model registration request]

A double-pipe thermal system consisting of an inner tube through which a corrosive heat medium such as seawater passes, and an outer tube into which this inner tube is inserted and which allows a refrigerant to flow through a flow path formed between the inner tube and the inner tube. an exchanger, a resin pipe connected to the end of the inner pipe, a resin holder communicating with the hollow part of the resin pipe and protruding outward from the resin pipe, the hollow part of the resin pipe and the resin pipe; A metal holder inserted into the holder, a through hole provided at the bottom through which the metal holder was inserted, a cap screwed onto the free end of the resin holder, and a cap screwed onto the outer periphery of the metal holder. A heat exchanger characterized by comprising an O-ring that is in close contact with the resin holder and is sandwiched between the end face of the resin holder and the bottom face of the cap.
