Claims

[Scope of utility model registration request]

An outer tube that is open at both ends and serves as an inlet and outlet for the heat exchange fluid is arranged on the outer periphery of the inner tube, and an annular flow path for the heat exchange fluid is formed in an annular gap defined by the inner tube and the outer tube. At the same time, a cylinder is arranged on the outer circumference near each end of the outer tube, a side hole is provided on the outer circumferential surface of each cylinder, an inlet pipe or an outlet pipe for the heat exchange fluid is attached to the side hole, and , on the outer peripheral surface of the inner tube so that each end of the cylinder has a gap located outside each end of the outer tube and serving as an inlet or an outlet for a heat exchange fluid between the outer tube and the outer tube. and an end plate located inside each end of the outer tube and attached to the outer peripheral surface of the outer tube to form a sealed structure within the cylinder, and the gap has an annular dimension. A double-pipe heat exchange device that is set to be shorter than a gap in a flow path, and the outer circumferential area of the gap is smaller than an annular area of the gap.
