Abstract
Description
Technical Field
[0001] This utility model relates to the field of combined heat sink technology, and in particular to a combined heat sink for a power supply box. Background Technology
[0002] In electronic devices, the power supply box, as a core power supply component, generates a significant amount of heat during operation. If this heat cannot be effectively dissipated, it can lead to overheating of internal components, affecting device stability and even shortening its lifespan. Traditional heat dissipation solutions typically involve fixing heat sinks or fans directly to the outer wall of the power supply box to prevent overheating.
[0003] However, the existing power supply heatsinks are not easy to install or remove. Most existing power supply heatsinks are fixed with screws or glue. The installation and removal of screws takes a long time, and the repeated tightening of screws for a long time can easily cause the screw surface to strip, affecting the stability of the heatsink position. As for glue fixation, it is easy to peel off at high temperatures, which also affects the stability of the heatsink position. Utility Model Content

[0046] The positioning mechanism 3 is used to lock and limit the multiple heat dissipation fins 24. The positioning mechanism 3 includes a positioning frame 31, a locking block 32 and a screw 33. The positioning frame 31 is locked to the ends of two opposing protective plates 22. The positioning frame 31 has a U-shaped structure.

[0047] In addition, the latching mechanism 4 includes a positioning block 41, a slide groove 42, rollers 43, a movable groove 44, and a limiting component 45.

The limiting block 455 is inserted and engaged with the inner cavity of the positioning hole 52. By pulling the fixing rod 454, the pull rod 451 can be pulled down, compressing its compression spring 452 and causing the tape body to... 51 can move stably in the inner cavity of the slide groove 42. When the fixing rod 454 is released, under the elastic support of the compression spring 452, the limiting block 455 can insert and snap onto the belt 51, so that the belt 51 can be bound to the bottom of the power box 1. The protective pad 53 is snapped onto the corners of the belt 51 and the power box 1.
