[0024] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] like Figure 1-5 As shown, the auxiliary power supply with power factor correction includes a power supply body 1 and a housing 2. The housing 2 has an insertion port 21 on the front and a heat dissipation vent 22 on the rear. This front-to-back arrangement creates an airflow path, aiding in heat dissipation for the power supply body 1. Several adjusting posts 3 are located on both sides of the housing 2. The adjusting posts 3 are threadedly connected to the housing 2, and their positions can be changed by rotating them to accommodate power supply bodies 1 of different sizes, thus improving the power supply's installation versatility. Because different power supply models may have different sizes, the adjusting posts 3 allow for flexible adjustment of the internal space of the housing 2 to accommodate them.
[0026] One end of the adjusting column 3 is located on the inner wall of the enclosure 2 and abuts against the outer wall of the power supply body 1. Its function is to securely fix the power supply body 1 inside the enclosure 2. Several adjusting columns 3 are distributed on the side walls of the enclosure 2, with no fewer than 6 adjusting columns 3 on each side wall of the enclosure 2. A larger number of distributed adjusting columns 3 can apply pressure to the power supply body 1 more evenly, further improving the stability of the power supply body 1 inside the enclosure 2. Moreover, adjusting columns 3 can also be provided on each side wall of the enclosure 2, thus maximizing the fixing effect on the power supply body 1. The other end of the adjusting end is located on the outer side of the enclosure 2, and the adjusting end has an adjusting hole 31. An adjusting tool, such as a screwdriver, can be inserted into the adjusting hole 31 to adjust the length of the adjusting column 3 screwed into the enclosure 2. The adjusting hole 31 can be a common shape such as a flathead or cross-shaped hole to facilitate the use of corresponding adjusting tools. The adjusting column 3 moves on the side wall of the housing 2 by rotating. When the adjusting column 3 is rotated to extend into the inner wall of the housing 2, it can abut against the power supply body 1 and play a fixing role; conversely, rotating it to pull it outward can loosen the fixation on the power supply body 1.
[0027] A cooling fan 23 is installed at the heat dissipation vent 22, blowing air towards the inside of the enclosure 2. An elastic sealing ring 10 is installed at the insertion port 21 to seal the gap between the power supply body 1 and the enclosure 2. The cooling fan 23 accelerates airflow and improves heat dissipation. The elastic sealing ring 10 prevents external dust and moisture from entering the enclosure 2, protecting the power supply body 1. A heat dissipation channel 32 is provided at the end of the adjustment column 3 that contacts the power supply body 1. The heat dissipation channel 32 extends along the length of the adjustment column 3. Several exhaust ports 33 are provided on the outer wall of the end of the adjustment column 3 near the adjustment hole 31. The exhaust ports 33 communicate with the heat dissipation channel 32 and are located on the outside of the enclosure 2. This allows the air blown by the cooling fan 23 to be exhausted through the heat dissipation channel 32 and the exhaust ports 33, further enhancing the heat dissipation effect. A beveled cut 34 is provided at the end of the adjustment column 3 that contacts the power supply body 1, facing the cooling fan 23. This better guides airflow into the heat dissipation channel 32.
[0028] Both ends of the housing 2 are equipped with heat dissipation covers 4, each with several heat dissipation holes 41. The heat dissipation covers 4 are used to cover several adjusting columns 3, and are connected to the housing 2 by screws 42. The heat dissipation covers 4 further protect the adjusting columns 3, and the heat dissipation holes 41 assist in heat dissipation. The heat dissipation covers 4 are connected to the housing 2 by screws 42, facilitating installation and disassembly.
[0029] The implementation principle of this embodiment is as follows: By setting adjustable adjustment columns 3 on both sides of the housing 2, it is possible to flexibly adjust according to the size of different power supply bodies 1, thereby improving the compatibility between the power supply and the housing 2 and solving the problem of poor universality of traditional power supply boxes. At the same time, the exhaust port 33 on the support column is connected to the heat dissipation channel 32, and the exhaust port 33 is located on the outside of the housing 2. Furthermore, a beveled cut 34 facing the cooling fan 23 is provided at the end of the adjustment rod that contacts the power supply body 1. The beveled cut 34 acts as a guide, allowing the air blown by the cooling fan 23 to enter the heat dissipation channel 32 more easily, thereby maximizing the heat dissipation effect.
[0030] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
