A plurality of heat exchange tubes 03 are arranged in the pipe fitting 01. Both ends of the heat exchange tubes 03 are connected to the pipe disc 02 respectively.

[0004] When the length of the pipe fitting 01 is very long, the length of the heat exchange tube 03 will also be very long. Since the diameter of the heat exchange tube 03 is very small, the heat exchange tube 03 needs to be supported and fixed.

[0005] It is common to use a disc-shaped support plate to support and fix the heat exchange tube 03. The diameter of the support plate is equal to the inner diameter of the pipe 01. The support plate is provided with a hole for the heat exchange tube 03 to pass through. When this circular support plate is used, there is a problem of affecting the flow of liquid in the pipe 01.

[0006] Therefore, some solutions in the prior art are to change the circular support plate into a semicircular structure, and multiple semicircular support plates are staggered to solve the above-mentioned problem of affecting the flow of liquid.

[0007] However, the semicircular support plate has good support only on the side where the support plate contacts the wall of the pipe 01, while the support on the other side where the support plate does not contact the wall is slightly lacking. Utility Model Content

[0010] A heat exchange tube support and fixing structure comprises a circular support plate, the support plate is provided with connecting grooves penetrating two sides thereof, and the support plate is distributed with through holes for the heat exchange tubes to pass through.

[0011] The utility model is further configured that the support plate comprises a first support plate and a second support plate, the connecting groove is arranged at a central position of the first support plate, and the connecting groove is arranged at an edge position of the second support plate.

[0012] The utility model is further configured such that the edges of the first support plate and the second support plate are provided with serial connection holes, and also include serial connection rods, which are inserted into the serial connection holes, and the serial connection rods are threadedly connected with positioning nuts, which are arranged on both sides of the support plates.

[0013] The utility model is further configured that a tubular balancing tube is provided at the edge of the supporting plate, and the supporting plate is located at the middle position of the axial direction of the balancing tube.

[0014] The utility model is further configured that, in the axial direction of the support disk, the communicating grooves on the first support disk and the second support disk are staggered.

[0015] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0016] The heat exchange tube support and fixing structure provided by the utility model, when in use, the circular support plate is adapted to the inner wall of the tube fitting, the support plate and the inner wall of the tube fitting form comprehensive contact, the support stability is high, and a connecting groove is provided on the support plate, the connecting groove can allow fluid to pass through, the first support plate and the second support plate cooperate to form support for all the heat exchange tubes without hindering the flow of the fluid.
