[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0018] Reference Figures 2 to 3, a high-power radio frequency coaxial cable cabin heat dissipation device that is easy to disassemble, comprising a cabin wall 1, and a radio frequency coaxial cable line 2 that is arranged through the cabin wall;

[0019] The outer sheath of the radio frequency coaxial cable is removed at the position where the radio frequency coaxial cable passes through the bulkhead and at the front and rear positions, that is, the sheath of the radio frequency coaxial cable is peeled off, and the outer conductor of the coaxial cable is passed through the bulkhead;

[0020] A front heat dissipation flange 3 and a rear heat dissipation flange 4 are respectively arranged on both sides of the bulkhead 1, and heat dissipation fins 5 are arranged on the outer sides of the front heat dissipation flange 3 and the rear heat dissipation flange 4, and cable holes are opened in the middle of the front heat dissipation flange and the rear heat dissipation flange;

[0021] The front heat dissipation flange and the rear heat dissipation flange are both formed by splicing a symmetrical two-petal structure, and the front heat dissipation flange and the rear heat dissipation flange are soldered to achieve the fixation of the cable and the sealing inside and outside the cabin. In order to ensure the sealing, the front heat dissipation flange and the rear heat dissipation flange are both sleeved on the part where the outer sheath of the RF coaxial cable is stripped;

[0022] The heat sink is arranged around the middle connection point, so as to maximize the heat dissipation. In the case of high-power transmission, the heat generated by the cable welding point is transferred to the heat dissipation flange with the heat sink through tin brazing, so as to effectively dissipate heat, reduce the cable temperature and improve reliability.

[0023] A metal layer that is easy to solder is plated on the surface of the front heat dissipation flange and the rear heat dissipation flange to provide solderability and facilitate soldering for fixation. The specific metal layer can be silver or gold.

[0024] In order to further improve the sealing performance, sealing rings are provided between the front heat dissipation flange and the bulkhead surface and between the rear heat dissipation flange and the bulkhead surface to ensure the sealing performance between the flange and the bulkhead;

[0025] The front heat dissipation flange or rear heat dissipation flange with a larger size and area and equipped with heat sinks allows a larger hole to be opened on the warehouse wall so that the connectors at both ends of the cable, which are thicker than the cable, can pass through the warehouse wall, while realizing that one cable can connect the inside and outside of the cabin.

[0026] In this implementation scheme, the position where the RF coaxial cable needs to be welded is peeled, and then it passes through the bulkhead. At the same time, the peeled part is placed at the center of the insertion point, and then the front heat dissipation flange and the rear heat dissipation flange are respectively set along the front and back of the RF coaxial cable, and attached to the corresponding bulkhead surface. The outer conductor of the RF coaxial cable is fixed to the heat dissipation flange by tin soldering, so that the cable is fixed and the inside and outside of the cabin are sealed. If it needs to be disassembled later, the tin soldering position is heated. Since the front and rear flanges are spliced ​​with a symmetrical two-petal structure, half of the flange part is removed after heating, so that it can be disassembled without taking out the cable, which is convenient for replacement;

[0027] The benefits of the utility model are that the flange of the technical solution is spliced ​​with a symmetrical two-petal structure, which is convenient for disassembly and replacement in the later stage, thereby improving efficiency; the penetration point of the RF coaxial cable is peeled, and the outer conductor of the RF coaxial cable is directly soldered to the heat dissipation flange, thereby achieving the fixation of the cable and the sealing inside and outside the cabin; at the same time, under the condition of high-power transmission, the heat generated by the cable welding point accessories is conducted to the heat dissipation flange with heat sink through soldering, thereby effectively dissipating heat, reducing the cable temperature, and improving reliability.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
