Description

Technical Field

[0001] The utility model relates to the technical field of electronic heat dissipation, in particular to a support plate for heat dissipation of electronic products. Background Art

[0002] The support plate for heat dissipation of electronic products mainly refers to the components that play the role of supporting structure and helping to dissipate heat in electronic products. It usually has the following characteristics and functions: providing a stable installation foundation for electronic components and maintaining the stability of the internal structure of electronic products. It can conduct away the heat generated by electronic products when they are working, help the heat dissipation system to play a better role, and prevent electronic components from being damaged or performance degradation due to overheating.

[0003] On the support plate for heat dissipation of electronic products, the air-cooled radiator is usually set at the bottom of the electronic device. Although such a layout can meet the heat dissipation needs to a certain extent, it also has some limitations. Since the air-cooled radiator is at the bottom, it makes it difficult for the upper end surface and vertical surface of the electronic product to be directly blown to dissipate heat. Specifically, when the air-cooled radiator is working, the airflow it generates is mainly concentrated at the bottom and diffuses to the surroundings. As for the upper end surface of the electronic product, it is far away from the air-cooled radiator at the bottom, and it is difficult for the airflow to effectively reach and take away the heat. For the vertical surface, it is also difficult for the airflow to act directly on these areas, because the flow characteristics of the air cause it to gradually weaken and disperse when it flows upward or sideways, and it is impossible to form a continuous and effective heat dissipation effect on these areas. Therefore, a support plate for heat dissipation of electronic products is proposed herein. Utility Model Content

[0022] The elastic mechanism includes a spring sleeved on the outside of the T-shaped rod 11, and the two ends of the spring are elastically connected to the outer wall of the head of the T-shaped rod 11 and the outer wall of the support plate body 1 respectively. The elastic potential energy provided by the spring ensures that one end of the T-shaped rod 11 is stably in the annular limit groove, preventing the rotating ring 4 from moving in the annular rotating groove 3.

[0023] The transmission mechanism includes a gear 13 mounted on a transmission shaft 12 . A gear ring 14 meshing with the gear 13 is provided on the arcuate inner wall of the rotating ring 4 . The teeth of the gear ring 14 are provided on the arcuate inner wall and meshing with the teeth on the arcuate outer wall of the gear 13 .

[0024] The rotating mechanism includes a pulley 8 installed on the transmission shaft 12 and the fan shaft of the fixed fan 7. The two pulleys 8 are connected by a belt 9. The pulley 8 and the belt 9 realize the simultaneous rotation of the fan assembly in the fixed fan 7 and the transmission shaft 12.

The rotating ring 4 relies on the fixed frame 5 to drive the movable fan 6 to rotate. In this way, the all-round blowing and cooling of the electronic product body 2 is finally achieved.
