[0028] Example 1

[0029] This embodiment provides a heat dissipation device for an auxiliary power module to prevent power sway. Figure 1-Figure 5 As shown, it includes a main body 1, a heat sink 4 and a fastening assembly, a guide groove 2 is opened on one side wall of the main body 1, and air outlets 3 are arranged at both ends of the main body 1, and the air outlets 3 are connected to the guide groove 2; the heat sink 4 is arranged at the notch of the guide groove 2, and a heat conductive silicone sheet 5 is arranged on the side of the heat sink 4 away from the main body 1; the fastening assembly is arranged on the side of the heat sink 4 away from the main body 1, and at least two of the fastening assemblies are arranged on both sides of the heat conductive silicone sheet 5; the fastening assembly includes a fastener 6, and the fastener 6 includes a connecting column 61, a first slider 62, a first driving rod 63 and a clamping plate 64, the connecting column 61 is arranged on the side of the heat sink 4 away from the main body 1, the first slider 62 is slidably arranged on the connecting column 61, the first driving rod 63 is passed through the connecting column 61, and the first driving rod 63 is connected to the first slider 62, the first driving rod 63 is used to drive the first slider 62 along the connecting column 61 to approach or move away from the heat sink 4; the clamping plate 64 is connected to the first slider 62, and the clamping plate 64 is used to abut the anti-power sway auxiliary power supply module against the thermal conductive silicone sheet 5.

[0030] Exemplarily, during the implementation process, a heat-conducting silicone sheet 5 is provided on one side of the heat-conducting silicone sheet 4, and a fastening assembly is provided on both sides of the heat-conducting silicone sheet 5, and the fastening assembly includes a fastener 6, and the fastener 6 includes a connecting column 61, a first slider 62, a first driving rod 63 and a clamping plate 64. Among them, the connecting column 61 is connected to one side of the heat-conducting plate 4 by welding, screwing, etc., and the first slider 62 is slidably arranged on the connecting column 61, and can slide along the connecting column 61 in the direction close to or away from the heat-conducting silicone sheet 5. The first driving rod 63 is penetrated on the connecting column 61, and the first driving rod 63 is connected to the first slider 62, so that the staff can drive the first slider 62 to slide along the connecting column 61 in the direction close to or away from the heat-conducting silicone sheet 5 through the first driving rod 63. The clamping plate 64 is connected to the first slider 62 by welding, screwing, etc., and can follow the first slider 62 to slide along the connecting column 61 in the direction close to or away from the heat-conducting silicone sheet 5.

[0031] A guide groove 2 is provided on the side wall of the main body 1, a heat sink 4 is provided at the notch of the guide groove 2, and the main body 1 is connected to the side of the heat sink 4 away from the thermal conductive silicone sheet 5 by welding, screwing, etc. Air vents 3 are provided at both ends of the main body 1, and the two air vents 3 are connected to the guide groove 2.

[0032] When in use, the anti-power-shaking auxiliary power module is first placed on the thermally conductive silicone sheet 5 of the heat sink 4. On the one hand, the thermally conductive silicone sheet 5 acts as a heat conduction medium, effectively enhancing the heat transfer efficiency between the anti-power-shaking auxiliary power module and the heat sink 4. On the other hand, the heat sink 4 effectively increases the heat dissipation area, so that heat energy can be quickly transferred to the surface of the heat sink 4.

[0033] Secondly, the first driving rod 63 drives the first slider 62 to move toward the direction close to the thermally conductive silicone sheet 5, thereby driving the clamping plate 64 to move toward the direction close to the thermally conductive silicone sheet 5, so as to press the anti-electrical sway auxiliary power supply module onto the thermally conductive silicone sheet 5. On the one hand, the dynamic adjustment of the pressure of the anti-electrical sway auxiliary power supply module is realized, so that it is convenient to adjust the clamping force according to actual needs to ensure that the anti-electrical sway auxiliary power supply module is tightly fitted on the thermally conductive silicone sheet 5, thereby optimizing the thermal conductivity performance. On the other hand, the anti-electrical sway auxiliary power supply module is pressed onto the thermally conductive silicone sheet 5 by the fastener 6, so that even when the equipment is subjected to vibration or external force impact, the position of the anti-electrical sway auxiliary power supply module can be kept unchanged, thereby improving the reliability and stability of the heat dissipation device and maintaining good thermal contact. On the other hand, it is convenient to fix anti-electrical sway auxiliary power supply modules of different thicknesses.

[0034] At the same time, the airflow enters from the air outlet 3 at one end of the main body 1, passes through the guide groove 2, and is discharged from the air outlet 3 at the other end of the main body 1. When the airflow passes through the guide groove 2, the airflow can take away the heat on the surface of the heat sink 4, thereby significantly improving the heat dissipation capacity of the anti-power sway auxiliary power module, thereby extending the service life of the anti-power sway auxiliary power module and reducing the failure rate.

[0035] Example 2

[0036] like Figure 5 As shown, based on the above embodiment 1, in this embodiment, a heat dissipation groove 7 is provided on one side of the heat dissipation plate 4 close to the main body 1; the heat dissipation groove 7 extends from one end of the main body 1 to the other end of the main body 1.

[0037] Exemplarily, during the implementation process, a heat dissipation groove 7 is opened on one side of the heat dissipation plate 4 close to the main body 1 , and the heat dissipation groove 7 extends from one end to the other end of the main body 1 .

[0038] During use, when the airflow passes through the guide groove 2, part of the airflow will enter the heat dissipation groove 7 and directly act on the heat dissipation plate 4. On the one hand, it accelerates the heat dissipation from the surface of the heat dissipation plate 4, thereby enhancing the heat dissipation efficiency. On the other hand, the existence of the heat dissipation groove 7 helps to distribute the heat more evenly on the heat dissipation plate 4, thereby reducing the local overheating phenomenon, reducing the formation of hot spots, and making the heat dissipation more uniform.

[0041] Exemplarily, during the implementation process, a first slide groove 8 is opened on the connecting column 61, and the first slide groove 8 extends along the main body 1 toward the heat sink 4. The first slider 62 is adapted in the first slide groove 8, so that the first slider 62 can slide in the first slide groove 8, thereby achieving the purpose of ensuring the stability and accuracy of the first slider 62 during sliding.

[0042] The first driving rod 63 is a threaded rod, which is rotatably connected to the groove wall of the first slide groove 8, and the first driving rod 63 is screwed to the first slider 62. During use, the first driving rod 63 is rotated clockwise from the end of the first driving rod 63 away from the main body 1, and the first slider 62 slides along the first slide groove 8 in a direction away from the thermal conductive silicone sheet 5 when the first slide groove 8 is limited; the first driving rod 63 is rotated counterclockwise from the end of the first driving rod 63 away from the main body 1, and the first slider 62 slides along the first slide groove 8 in a direction close to the thermal conductive silicone sheet 5 when the first slide groove 8 is limited. On the one hand, by rotating the first driving rod 63, the first slider 62 is driven to move linearly along the first slide groove 8, so as to achieve the purpose of realizing the precise adjustment of the position of the first slider 62, thereby improving the accuracy and controllability of the operation of the fastening assembly. On the other hand, compared with simple sliding or direct push-pull, the rotation connection and screw connection can provide better mechanical stability, reduce wear between components, and extend service life.

The second driving rod 65 is inserted into the through hole 9, and one end of the second driving rod 65 is connected to the clamping plate 64 by welding, screwing, etc. A spring 66 is sleeved on the second driving rod 65, and the two ends of the spring 66 are respectively abutted against the clamping plate 64 and the side of the connecting column 61 close to the thermally conductive silicone sheet 5. The other end of the first driving rod 63 abuts against the side of the connecting column 61 away from the thermally conductive silicone sheet 5 under the action of the elastic force of the spring 66.

[0046] During use, the second driving rod 65 is pulled from the end of the second driving rod 65 away from the clamping plate 64 to move the clamping plates 64 on both sides of the thermally conductive silicone sheet 5 away from each other. After the anti-power sway auxiliary power supply module is placed on the thermally conductive silicone sheet 5 of the heat sink 4, the second driving rod 65 is released. At this time, under the action of the restoring force of the spring 66, the clamping plates 64 on both sides of the thermally conductive silicone sheet 5 clamp and fix the anti-power sway auxiliary power supply module. On the one hand, the risk of the anti-power sway auxiliary power supply module sliding along one side of the thermally conductive silicone sheet 5 to the other side of the thermally conductive silicone sheet 5 is reduced. On the other hand, the purpose of facilitating the fixing of anti-power sway auxiliary power supply modules of different widths on the thermally conductive silicone sheet 5 is achieved.
