[0002] In the field of antennas, the transmitting components, i.e., radio frequency components, and several signal receiving and transmitting tools are generally mounted on a metal plate. However, the problem of needing to dissipate heat from multiple heat sources simultaneously is frequently encountered. During the operation of these electronic products, heat is inevitably generated, causing the temperature of the internal components to rise. In particular, certain local component concentration areas may generate high temperatures, which not only damage their own performance but also reduce the performance reliability of the entire system, or even lead to system failure. Therefore, how to concentrate the heat from the heat sources and how to reduce the surface temperature of the electronic product casing require an effective method to dissipate the heat generated by the internal components of these electronic products. To this end, this application proposes a heat source heat conduction tool that rotates up and down to solve the above-mentioned shortcomings. Utility Model Content

The heat source is installed on the metal plate 2, and the heat generated by the heat source is conducted to the metal plate 2, and then conducted to the heat dissipation base 1 through the transmission heat conduction component 3. The heat dissipation base 1 carries away the heat, thereby realizing heat transfer from top to bottom, and thus realizing rapid heat conduction of the heat source on the metal plate.

[0027] Reference Figure 1 and Figure 3 The top of the heat dissipation base 1 is provided with a connecting part 102 for connecting with the transmission heat conduction component 3. A recessed heat distribution plate mounting groove 103 is also provided on the heat dissipation base 1 and the outer side of the connecting part 102. A heat distribution plate 310 is installed on the heat distribution plate mounting groove 103. It should be noted that the heat distribution plate mounting groove 103 and the heat distribution plate 310 can be set in several according to the size of the heat dissipation base 1. This application does not limit it. The heat distribution plate can transfer heat to the entire heat dissipation base 1 through internal heat transfer. The bottom of the heat dissipation base 1 is provided with several heat dissipation plates, which can quickly remove heat, so that heat transfer from top to bottom can be realized.

[0028] Several sets of outwardly protruding fixing blocks 101 are provided on the outer side of the heat dissipation base 1. The fixing blocks 101 are provided with mounting holes for subsequent installation on the corresponding equipment or the required position.

[0029] Reference Figure 1 and Figure 3 The metal plate 2 has several mounting slots for mounting heat sources. In this application, the heat source is a transmitting component used on the antenna, i.e., a radio frequency component. The metal plate 2 is also equipped with several tools for receiving and transmitting signals. The number of heat sources can be installed, and this application does not limit the number. When in use, the heat generated by the heat source and various signal transceivers will be conducted to the heat dissipation base 1 through the transmission heat conduction component 3 for heat dissipation treatment.

[0030] Reference Figure 4 and Figure 6 The transmission heat conduction assembly 3 includes an inner bearing housing 301, an upper heat conduction pad 302, an upper graphite packing 303, an outer bearing housing 304, an outer bearing cover plate 305, an inner bearing cover plate 306, a bearing 307, a lower graphite packing 308, and a lower heat conduction pad 309.

[0031] The inner bearing housing 301 is located at the top. The inner bearing housing 301 is provided with three outwardly extending mounting protrusions: mounting protrusion one 3011, mounting protrusion two 3012, and mounting protrusion three 3013. Mounting holes are provided on mounting protrusion one 3011, mounting protrusion two 3012, and mounting protrusion three 3013, which can be detachably mounted to the metal plate 2 by means of screws or pins.

[0032] The outer bearing housing 304 is located below the inner bearing housing 301. The top of the outer bearing housing 304 is detachably connected to the outer bearing cover plate 305 by bolts or pins. The outer bearing cover plate 305 is located between the inner bearing housing 301 and the outer bearing housing 304. A bearing 307 is installed inside the outer bearing housing 304. The outside of the bearing 307 is fixed to the inside of the outer bearing housing 304, and the inside of the bearing 307 is fixed to the bottom of the inner bearing housing 301. Thus, the inner bearing housing 301 can rotate relative to the outer bearing housing 304 under the action of the bearing 307. An inner bearing cover plate 306 is installed on the bottom inner side of the outer bearing housing 304. The inner bearing cover plate 306 can be connected to the connecting part 102 on the heat sink base 1.

[0033] Furthermore, an upper graphite packing 303 is installed on the inner side of the inner bearing housing 301, and a lower graphite packing 308 is provided below the upper graphite packing 303.

When the upper graphite packing 303 rotates with the inner bearing housing 301, it will not affect the lower graphite packing 308. An upper thermal pad 302 is also installed above the upper graphite packing 303, and a lower thermal pad 309 is installed below the lower graphite packing 308.

[0034] The specific operating principle of this application is as follows:

[0035] During operation, the metal plate 2 rotates, and the heat from the heat source is conducted through the metal plate 2 to the inner bearing seat 301, and then from the inner bearing seat 301 to the upper graphite packing 303 through the upper thermal pad 302. Since the upper graphite packing 303 and the lower graphite packing 308 are pressed together, the heat is conducted from the upper graphite packing 303 to the lower graphite packing 308, and then the lower graphite packing 308 conducts the heat to the heat spreader 310. The heat spreader 310 transfers the heat to the entire heat dissipation base 1 through internal heat transfer, thus carrying away the heat and achieving heat transfer from top to bottom.

[0036] In this application, thermally conductive silicone grease is applied to the contact surface between the bearing 307 and the upper graphite packing 303; thermally conductive silicone grease is also applied to the contact surface between the inner bearing housing 301 and the metal plate 2; thermally conductive silicone grease is also applied between the lower graphite packing 308 and the connecting part 102. The function of the thermally conductive silicone grease and thermal pad in this application is to reduce the thermal resistance of the contact surface.
