[0022] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] Combination Figure 1 and Figure 4 As shown, a spliced ​​cooling duct that is easy to install includes a ventilation pipe 3, one end of the ventilation pipe 3 is fixedly connected to a second flange 5, and the other end is fixedly connected to a bellows 2. The bellows 2 is flexible and has the ability to shrink axially. When multiple ventilation pipes 3 are spliced, the error caused by axial installation can be eliminated, which is convenient for installation. The other end of the bellows 2 is fixedly connected to a first flange 1. The edges of the first flange 1 and the second flange 5 are both provided with openings 15. When the ventilation pipes 3 are spliced, the first flange 1 and the second flange 5 are aligned, and the position of the opening 15 is also correspondingly arranged. A screw 16 is rotatably arranged at the opening 15 of the first flange 1, and a nut 17 is threadedly arranged on the screw 16. After aligning the first flange 1 and the second flange 5, the screw 16 is rotated to cross the opening 15, and then the nut 17 is rotated to tighten, so that the two ventilation pipes 3 are connected.

[0024] like Figure 2 As shown, a heat exchange tube 14 is provided inside the ventilation tube 3. A refrigerant is passed through the heat exchange tube 14 to cool the air in the ventilation tube 3. Water is usually used as the refrigerant. The heat exchange tube 14 is spirally arranged and has a conical structure. The structure allows the passing air to contact with it as much as possible to fully exchange heat. At the same time, the structure is relatively simple to produce. The pipe is obtained by extrusion molding. The material is aluminum alloy, which is then bent and wound into the structure shown in the figure. Due to the use of an integrated molding method, the risk of water leakage can be reduced.

[0025] A support is provided inside the ventilation pipe 3 for supporting and fixing the heat exchange pipe 14 .

[0026] like Figure 1As shown, a clamp 4 is provided on the ventilation pipe 3, and each ventilation pipe 3 is provided with three clamps 4. The number of the clamps 4 can be directly increased or decreased according to the length of the ventilation pipe 3. The clamp 4 is sleeved on the ventilation pipe 3, and the side wall of the clamp 4 is fixedly connected with a support rod 6, and the support rod 6 is a round tube. The other end of the support rod 6 is fixedly connected with a connecting plate 12. Through holes are provided on both sides of the connecting plate 12 for passing a connecting piece, such as a screw. If the ventilation pipe 3 is fixedly connected to the upper part of the room, the connecting plate 12 is fixedly connected to the ceiling for ceiling connection.

[0027] The side wall of the support rod 6 is fixedly connected with a support member 10, the cross-sectional shape of the support member 10 is consistent with the cross-sectional shape of the channel steel, and the support rod 6 passes through the middle of the support member 10. The first water pipe 7 and the second water pipe 9 are placed on the support member 10, one of which is used to introduce the refrigerant, and the other water pipe is used to send out the refrigerant after heat exchange.

[0028] The first water pipe 7 and the second water pipe 9 have the same structure, with a threaded section provided on the side wall at one end and a rotating member 13 which cooperates with the threaded section rotatably provided at the other end. That is, when adjacent ventilation pipes 3 are connected, the adjacent first water pipes 7 and second water pipes 9 also need to be connected, that is, the rotating member 13 is threadedly fitted on the threaded section, and a sealing gasket is provided at the connection. Before the ventilation pipe 3 is installed, the connection between the first water pipe 7 and the second water pipe 9 is preferentially realized, and the provided bellows 2 can balance the error caused by the ventilation pipe 3.

[0029] like Figure 2 As shown, one end of the heat exchange tube 14 is fixedly connected to the second connecting tube 11, the other end of the second connecting tube 11 is fixedly connected to the second water pipe 9, one end of the heat exchange tube 14 is fixedly connected to the first connecting tube 8, and the other end of the first connecting tube 8 is fixedly connected to the first water pipe 7. Through the first connecting tube 8 and the second connecting tube 11, the two ends of the heat exchange tube 14 are respectively connected to the first water pipe 7 and the second water pipe 9, so as to realize the circulation of the refrigerant and perform heat dissipation.

[0030] like Figure 3 As shown, the heat exchange tube 14 includes a tube body 142, and a plurality of heat sinks 141 are arranged at equal angles on the side wall of the tube body 142. When the heat sinks 141 are used, the heat dissipation area is increased, thereby improving the heat dissipation efficiency.
