本考案は、外殻管内に複数の内管を配設した螺
旋状の二重管式熱交換器に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a spiral double-tube heat exchanger in which a plurality of inner tubes are disposed within an outer shell tube.

にろう付けした後、該外殻管を螺旋状に形成した
ものである場合は、外殻管内の外周側と内周側の
長さが異なるから、外周側に位置する内管は冷媒

在化し、熱交換が均一に行なわれなくなつて、熱
交換率を低下させるという問題点を有していた。(Problems to be Solved by the Invention) In the conventional double-tube heat exchanger, each inner tube is disposed within an outer shell tube, and both ends of the inner tube are brazed to the refrigerant tube. If the outer shell tube is formed in a spiral shape, the lengths of the outer circumferential side and the inner circumferential side of the outer shell tube are different, so the inner tube located on the outer circumferential side is stretched at the connection with the refrigerant pipe. A force is generated, and compression pressure is generated in the inner pipe located on the inner circumferential side at the connection part with the refrigerant pipe. As a result, each inner tube is unevenly distributed toward the center of the outer shell tube, and heat exchange is no longer performed uniformly, resulting in a problem of lowering the heat exchange efficiency.

いるという問題点を有していた。 In addition, if both ends of the inner tube are brazed after forming the outer shell tube in a spiral shape, the copper tubes align and spring back during the spiral formation process, causing each inner tube to become unevenly distributed on the outer circumferential side. However, there was a problem in that the thermal efficiency was reduced.

がろう付けされ、冷媒管Ａ内に臨んでいる。 The end member 10 consists of a cylindrical body 11 and a pipe fitting 12 protruding from the outer peripheral wall of the cylindrical body 11.
2 is connected to a water tank (not shown) via a water pipe equipped with a pump. One open end of the cylindrical body 11 is fitted into the outer shell tube 1, and the other open end is covered with a cap 13. One end of a refrigerant pipe A of a cooling circuit (not shown) that passes through the cap 13 is inserted into the cylinder 11, and the end wall of the refrigerant pipe A is inserted into the cylinder 11.
One end of each inner tube 2 protruding from inside the outer shell tube 1 is brazed to A', and faces the inside of the refrigerant tube A.

内管２の管壁を介して熱交換が行なわれる。 In this embodiment, water from a water tank (not shown) is circulated through the outer shell pipe 1 by a pump and returned to the water tank, while refrigerant flowing through a cooling circuit (not shown) is pumped into each inner pipe 2. Heat exchange occurs between the water and the refrigerant through the tube walls of each inner tube 2.

偏在化して、熱効率が下がるということがない。 When forming the outer shell tube 1 in a spiral shape after brazing both ends of each inner tube 2, each inner tube 2 is twisted mutually within the outer shell tube 1 and is arranged evenly in a spiral shape. , the required length of each inner tube 2 is equal,
There is no longer any tensile force or compressive pressure generated on the end wall A' of the refrigerant pipe A as in the prior art. Furthermore, since the inner tubes 2 are arranged evenly within the outer shell tube 1, the heat exchange rate does not decrease. Even when forming the outer shell tube 1 into a spiral shape and then brazing both ends of the inner tube 2, since the entire inner tube 2 is mutually twisted, even after forming the outer shell tube 1 into a spiral shape, each length is Nothing is different. Therefore, the inner tubes 2 will not be unevenly distributed within the outer shell tube 1 and the thermal efficiency will not decrease.

ない。 Furthermore, since the spacer 3 is installed between the inner tubes 2, even if the inner tubes 2 are twisted together, the inner tubes 2 will not come into close contact with each other, reducing the effective heat exchange area and causing heat loss. There is no decrease in exchange efficiency.
