Claims

[Scope of utility model registration request]

An inner pipe that allows fluid to pass through the inside, an outer pipe that surrounds this inner pipe and performs heat exchange between the fluid that passes inside and the fluid in the inner vibe, and a second pipe that is connected to the inner vibe. It consists of a joint inner pipe that has one connection port at both ends, and a joint outer pipe that has a second connection port at both ends that is connected to the outer vibe, and the inner pipe is a metal pipe made of a metal with high thermal conductivity. The outer pipe is a resin pipe made of synthetic resin with low thermal conductivity, and each first connection port of the joint inner pipe is exposed within each second connection port of the joint outer pipe and is connected to each first connection port. The inner pipe of the joint is arranged at a fixed position within the outer pipe of the joint such that the inner vibrator and the outer bar and eve connected to each second connection port are spaced apart from each other, and the inner pipe of the joint and the outer pipe of the joint are arranged on the outer circumference of the inner pipe of the joint. Double tube structure for heat exchange fixed by fins protruding from the top.
