Claims

[Claims for Utility Model Registration] (1) In a double-tube heat exchanger in which an outer tube and an inner tube have a double-tube structure, and the fluid flowing in one side heats or cools the fluid flowing in the other, A sliding stiffener having a smaller diameter than the inner diameter of the outer tube is provided on the outer periphery of the outer tube, and a wrap joint having a collar smaller than the inner diameter of the outer tube is provided at one end of the inner tube, and the sliding stiffener is provided at the tip of the outer tube. A packing member is provided in contact with the outer circumferential surface of the moving part stiffener to make one end of the outer pipe watertight, and one end of the inner pipe is connected to other piping by sandwiching the collar of the wrap joint with a two-split inner pipe fixing flange. A double tube heat exchanger characterized in that it is configured to. (2) In a double-tube heat exchanger that has a double structure with an outer tube and an inner tube, and the fluid flowing in one side heats or cools the fluid flowing in the other, one end of the inner tube has a diameter smaller than the inner diameter of the outer tube. A wrap joint having a brim is provided, one end of the inner tube is connected to another pipe by sandwiching the brim of the wrap joint with a two-split inner tube fixing flange, and a telescoping tube that can be expanded and contracted in the axial direction is attached to one end of the inner tube. What is claimed is: 1. A double-tube heat exchanger, characterized in that the double-tube heat exchanger is fitted onto the outer periphery of the outer tube and has both ends connected to one end of the outer tube and one end of the inner tube in a watertight structure.
