[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 4As shown in the embodiment of this utility model, a heat dissipation structure for a microwave millimeter-wave power amplifier includes a cooling plate 1; an amplifier body 11 is placed on top of the cooling plate 1; a cooling pipe 12 is fixedly connected inside the cooling plate 1; the cooling pipe 12 is wavy; a first connecting pipe 13 is fixedly connected to the end of the cooling pipe 12; a storage container 14 is fixedly connected to the end of the first connecting pipe 13; a second connecting pipe 15 is fixedly connected to the middle of the storage container 14; a pump 16 is fixedly connected to the end of the second connecting pipe 15; the output end of the pump 16 is connected to the first connecting pipe 13; two fixing components 17 are fixedly connected to the top of the cooling plate 1; the two fixing components 17 are symmetrically arranged; during operation, the amplifier body 11 is placed on top of the cooling plate 1, and the fixing components 17 are used to fix the amplifier body 11, while the storage container 14... The amplifier is filled with coolant. When pump 16 is started, the coolant in storage tank 14 is drawn out. The coolant flows through the second connecting pipe 15 into the interior of cooling pipe 12. Through cooling pipe 12, the cooling capacity is transferred to cooling plate 1, thereby cooling the amplifier body 11 on top of cooling plate 1. After flowing out from the end of cooling pipe 12, the coolant enters the interior of storage tank 14 through the first connecting pipe 13. Through the above structure, the coolant can quickly absorb the heat generated by amplifier body 11 and carry it away, thereby effectively reducing the temperature of amplifier body 11. The amplifier body 11 is wavy, which increases the contact area between cooling pipe 12 and cooling plate 1, thereby improving heat dissipation efficiency. In addition, the coolant can be recycled, which can effectively reduce the amount of coolant discharged, thereby reducing environmental pollution.

[0026] like Figure 1 and Figure 3 As shown, the fixing assembly 17 includes a bracket 2; a screw 21 is threadedly connected to the top of the bracket 2; an adjusting handle 22 is fixedly connected to the top of the screw 21; a connecting plate 23 is rotatably connected to the bottom of the screw 21; a fixing plate 24 is fixedly connected to the side wall of the connecting plate 23; the fixing plate 24 contacts the side wall of the amplifier body 11; during operation, the amplifier body 11 is placed on top of the cooling plate 1, and the adjusting handle 22 is rotated. While the adjusting handle 22 is rotating, the screw 21 moves vertically. When the screw 21 moves, the connecting plate 23 moves, which in turn moves the fixing plate 24 to fix the amplifier body 11. Through the above structure, the amplifier body 11 can be effectively fixed, so that the amplifier body 11 is in close contact with the cooling plate 1, which improves the cooling effect. The amplifier body 11 may vibrate during operation. Fixing the amplifier body 11 to the cooling plate 1 can reduce the impact of vibration on the internal components of the amplifier body 11, thereby extending the service life of the amplifier body 11.

[0027] like Figure 4As shown, the amplifier body 11 has a ferromagnetic metal outer shell and multiple heat dissipation holes 3 evenly distributed on it. Two magnetic strips 31 are magnetically connected to the side wall of the amplifier body 11, arranged symmetrically. A filter screen 32 is fixed to the side wall of the magnetic strips 31, positioned corresponding to the heat dissipation holes 3. During operation, after prolonged use, the filter screen 32 may accumulate dust, hair, and other impurities. Since the magnetic strips 31 are magnetically connected to the amplifier body 11, removing the magnetic strips 31 from the amplifier body 11 allows for the quick removal of the filter screen 32. This structure facilitates cleaning and reduces the need for tools, making disassembly simple and efficient.

[0028] like Figure 1 and Figure 3 As shown, the side wall of the cooling plate 1 has two sliding grooves 4; the two sliding grooves 4 are symmetrically arranged; a guide rod 41 is slidably connected inside the sliding groove 4; the guide rod 41 is fixed to the side wall of the connecting plate 23; a fixing block 42 is fixed to the end of the guide rod 41; the fixing block 42 contacts the side wall of the bracket 2; during operation, when the screw 21 drives the connecting plate 23 to move, the guide rod 41 on the side wall of the connecting plate 23 slides inside the sliding groove 4, and when the guide rod 41 slides, it drives the fixing block 42 to slide along the side wall of the bracket 2. Through the above structure, the connecting plate 23 can be effectively guided, reducing the rotation of the connecting plate 23 during movement, so that the fixing plate 24 can fit more accurately with the amplifier body 11.

[0029] like Figure 3 As shown, a protective pad 5 is bonded to the side wall of the fixing plate 24; the protective pad 5 is made of rubber; during operation, the fixing plate 24 may directly contact the amplifier body 11, which may cause wear. The protective pad 5 is set on the fixing plate 24. The protective pad 5 is made of rubber and has good elasticity. Through the above structure, the protective pad 5 can effectively protect the cooling plate 1, reduce the wear of the fixing plate 24 on the amplifier body 11, and thus extend the service life of the amplifier body 11.

[0030] like Figure 2 As shown, two sets of anti-slip pads 6 are bonded to the bottom of the cooling plate 1; the two sets of anti-slip pads 6 are arranged symmetrically; when the cooling plate 1 is placed on the ground or table, it may slide due to external impact. By setting anti-slip pads 6 at the bottom of the cooling plate 1, the friction between the cooling plate 1 and the ground or table can be effectively increased, thereby reducing the sliding of the cooling plate 1 and making the amplifier body 11 more stable when working.

[0031] like Figure 1 and Figure 2 As shown, the cooling plate 1 is rectangular in shape; the material of the cooling plate 1 is aluminum alloy; when working, the cooling plate 1 is made of aluminum alloy, which has good thermal conductivity and mechanical properties. Through the above structure, the cooling plate 1 can effectively transfer cold energy, making the transfer effect better, and at the same time, it can withstand a certain pressure and impact, thus improving the overall structural strength of the heat dissipation structure.

[0032] During operation, the amplifier body 11 is placed on top of the cooling plate 1 and secured using the fixing assembly 17. The storage container 14 contains coolant. The extraction pump 16 is activated, drawing out the coolant from the storage container 14. The coolant flows through the second connecting pipe 15 into the cooling pipe 12, transferring its cooling capacity to the cooling plate 1, thereby cooling the amplifier body 11 on top of the cooling plate 1. The coolant then flows out from the end of the cooling pipe 12 and enters the storage container 14 through the first connecting pipe 13. This structure allows the coolant to quickly absorb and carry away the heat generated by the amplifier body 11, effectively reducing its temperature. The amplifier body 11 is arranged in a wave-like shape. This increases the contact area between the cooling pipe 12 and the cooling plate 1, thereby improving heat dissipation efficiency. Furthermore, the coolant can be recycled, effectively reducing coolant discharge and thus lowering environmental pollution. The amplifier body 11 is placed on top of the cooling plate 1. Rotating the adjustment handle 22 causes the screw 21 to move vertically, which in turn moves the connecting plate 23, which in turn moves the fixing plate 24 to fix the amplifier body 11. This structure effectively fixes the amplifier body 11, ensuring a tight fit between it and the cooling plate 1, thus improving cooling performance. The amplifier body 11 may vibrate during operation. The amplifier body 11 is fixed to the cooling plate 1, which reduces the impact of vibration on the internal components of the amplifier body 11, thereby extending the service life of the amplifier body 11. After long-term use, the filter screen 32 may accumulate a lot of dust, hair and other impurities on its surface. The magnetic strip 31 is magnetically connected to the amplifier body 11. By removing the magnetic strip 31 from the amplifier body 11, the filter screen 32 can be removed. Through the above structure, the filter screen 32 can be quickly removed, which is convenient for the staff to clean the filter screen 32. Moreover, the use of tools is reduced when removing the filter screen 32, making the removal method simple and convenient, and effectively improving the removal efficiency. When the screw 21 drives the connecting plate 23 to move, the guide on the side wall of the connecting plate 23... Rod 41 slides inside the groove 4. When guide rod 41 slides, it drives fixed block 42 to slide along the side wall of bracket 2. Through the above structure, the connecting plate 23 can be effectively guided, reducing the rotation of the connecting plate 23 during movement, so that the fixed plate 24 can fit more accurately with the amplifier body 11. Direct contact between the fixed plate 24 and the amplifier body 11 may cause wear. A protective pad 5 is provided on the fixed plate 24. The protective pad 5 is made of rubber and has good elasticity. Through the above structure, the protective pad 5 can effectively protect the cooling plate 1, reduce the wear of the fixed plate 24 on the amplifier body 11, and thus extend the service life of the amplifier body 11. When the cooling plate 1 is placed on the ground or table,The cooling plate 1 may slip due to external impact. To mitigate this, an anti-slip pad 6 is installed at the bottom of the cooling plate 1. This structure effectively increases the friction between the cooling plate 1 and the ground or tabletop, reducing slippage and making the amplifier body 11 more stable during operation. The cooling plate 1 is made of aluminum alloy, which has good thermal conductivity and mechanical properties. This structure allows the cooling plate 1 to effectively transfer heat, improving the heat transfer effect, while also withstanding certain pressure and impact, thus enhancing the overall structural strength of the heat dissipation structure.
