DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 3 A heat dissipation device for an LED power supply includes a box 1 for matching an LED power supply, and a cavity 2 is opened in the box 1. A protective through hole 3 is opened in the box 1 and communicates with the cavity 2 and passes through the upper and lower ends of the box 1. A support platform 27 is integrally connected to the bottom of the box 1. By arranging the support platform 27 at the four corners of the box 1, it is avoided that the box 1 and the LED power supply are tightly contacted when the box 1 is fixed, and then the high-temperature heat energy on the LED power supply is directed to the box 1 along with the gas during the process of wind heat dissipation.

[0024] First, the box body 1 is provided with a fixing mechanism for clamping the LED power supply through the support platform 27, and the fixing mechanism includes four through slots 14 opened in the bottom end of the box body 1, and strong springs 15 are fixedly welded in the four through slots 14, and a guide block 16 is welded at one end of the strong spring 15, and the guide block 16 is welded with a front hanging hook 17 and a rear hanging hook 18 for symmetrically clamping the LED power supply, and the front hanging hook 17 and the rear hanging hook 18 are both L-shaped structures, and the sagging height of the front hanging hook 17 and the rear hanging hook 18 exceeds the support platform 27, and a limited position through hole 19 is provided on the rear hanging hook 18;

[0025] The fixing mechanism also includes a limit bracket 20 fixedly welded on the box body 1, a reset spring 21 is welded to the bottom end of the limit bracket 20, and a limit plate 22 is fixedly welded to one end of the reset spring 21. A slot 23 for slidingly fitting the limit plate 22 is provided on both sides of the box body 1 and the limit bracket 20. A guide rod 24 that slides through the limit bracket 20 and is fitted in the reset spring 21 is welded on the limit plate 22. A limit column 25 corresponding to the limit through hole 19 is fixedly welded to one end of the guide rod 24, and a pull ring is also welded on the limit plate 22 for facilitating the lifting of the limit column 25.

[0026] Secondly, the box body 1 is provided with a heat dissipation mechanism for providing air cooling for the LED power supply through the cavity 2 and the protective through hole 3. The heat dissipation mechanism is divided into two parts. First, a driving motor 26 is fixedly installed at the bottom of the cavity 2. A cooling fan 4 is fixedly installed at the output end of the driving motor 26. Second, when the cooling fan 4 is operated for a long time, the dust filter plate 6 is very likely to absorb a large amount of air dust and form layers of dirt. In order to facilitate its maintenance, a component for fixing the dust filter plate 6 is provided on the box body 1 so as to facilitate its disassembly. Limiting grooves 5 are provided at the upper and lower ends of the cavity 2. The dust filter plate 6 is installed in the limiting groove 5. A bearing block 7, on which two groups of connecting strips 8 are movably mounted, the connecting strip 8 is T-shaped at one end close to the dust filter plate 6, and a compression block 9 is welded to the bottom end of the T-shaped connecting strip 8, a cylindrical cavity is opened in the compression block 9, a pressure spring 10 is fixedly welded in the cylindrical cavity, a compression column 11 is welded to the lower end of the pressure spring 10, a bonding plate 12 is movably mounted at the bottom end of the compression column 11, a spherical ball is movably sleeved between the compression column 11 and the bonding plate 12 for supporting the bonding plate 12 to rotate in any direction, a fixed handle 13 is movably mounted on the connecting strip 8, the bearing block 7 is pin-connected to the connecting strip 8, and the connecting strip 8 is pin-connected to the fixed handle 13.

[0027] It should be noted that the specific model and specifications of the drive motor 26 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] Adjust the position of the front hanging hook 17, place the heat sink just above the heating area of ​​the LED power supply, lift and drop the limit column 25, and insert it into the limit through hole 19, then fix the rear hanging hook 18 on the LED power supply, put the dust filter plate 6 along the limit groove 5, and then press the fixing handle 13. Through the elastic force of the pressure spring 10, the fitting plate 12 and the dust filter plate 6 will be in close contact;

[0030] By turning on the driving motor 26, the cooling fan 4 is driven to rotate, and the hot air generated by the power supply is driven from the bottom of the box body 1 through the cavity 2 to the top of the box body 1, so as to achieve a ventilation effect. Dust is also sucked in along with the hot air. At this time, the dust filter plate 6 blocks the dust and adsorbs it on the filter screen;

[0031] When too much dust accumulates on the dust filter plate 6, the driving motor 26 is stopped, the fixed handle 13 is pulled outward, the bonding plate 12 leaves the dust filter plate 6, and the dust filter plate 6 can be taken out for cleaning and maintenance.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
