Claims

[Claims for Utility Model Registration] 1. An inner tube through which high-temperature gas passes, and a double-pipe type in which heat is exchanged by passing fluid through the gap formed by the outer surface of the inner tube and the inner surface of the outer tube. In the heat exchanger, the fluid is applied along the end surface of the gap formed by the outer surface of the inner tube and the inner surface of the outer tube on the inlet and outlet sides of the fluid of the heat exchanger. A double-tube heat exchanger characterized in that guide members for inflow or outflow are provided on the inlet side and the outlet side of the exchanger, respectively. 2. A double pipe heat exchanger, wherein the guide member according to claim 1 has a substantially cylindrical shape.
