Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of a bare plate of a switching power supply, in particular to a heat dissipation type bare plate of a switching power supply. Background Art

[0002] The bare board switching power supply refers to a power board without a shell and without packaging. It is an important part of the power supply technology research and development process. The bare board power supply module uses better electronic components and more advanced circuit design, making it more stable and reliable, while effectively improving the conversion efficiency. This bare board power supply module can be directly inserted or connected to a printed circuit board (PCB) to provide working current for electronic equipment. The working principle of the bare board power supply module is the same as that of the switching power supply. It uses power semiconductor devices as switching elements and adjusts the output voltage by periodically turning on and off the switch and controlling the duty cycle of the switching element. At the same time, according to the application environment and the needs of electronic products, the bare board power supply module also has functions such as voltage transformation, isolation, and filtering.

[0003] At present, a bare switching power supply board generates a lot of heat during use, so the bare switching power supply board needs to be heat-dissipated. At present, the bare switching power supply board is generally cooled by a cooling fan. Although the cooling fan has a certain cooling effect, the cooling efficiency is limited. Although the cooling fan can generate airflow to help take away some heat, its cooling efficiency is relatively limited. Under high load or high temperature environment, the fan provides sufficient cooling effect, resulting in overheating of the equipment. At the same time, the blades of the cooling fan will adhere to more dust, which will increase the rotation resistance of the fan and reduce the speed and efficiency of the fan. Therefore, a heat-dissipating bare switching power supply board is proposed. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat dissipation type switching power supply bare board, comprising a switching power supply bare board, wherein the outer wall of the switching power supply bare board is provided with a heat dissipation mechanism;

[0007] Furthermore, the heat dissipation assembly includes two support bases fixedly mounted on the bottom outer wall of the bare board of the switching power supply, a heat conducting plate fixedly mounted on the bottom outer wall of the bare board of the switching power supply, a heat dissipation fin fixedly mounted on the bottom of the heat conducting plate, and support plates fixedly mounted on the outer walls on opposite sides of the two support bases.

[0008] Furthermore, a plurality of first heat dissipation holes are opened inside the support plate, the support plate is movably mounted on the bottom outer wall of the heat dissipation fins, and the length and width of the heat conduction plate are the same as the length and width of the heat dissipation fins.

[0009] Furthermore, two mounting holes are provided inside the mounting seat, two threaded holes are provided inside the mounting plate, and the bolts are slidably connected inside the mounting holes and threadedly connected inside the threaded holes and have matching sizes.

[0010] Furthermore, a card slot is formed on the outer wall of one side opposite to the two card seats, and the card rod is slidably connected inside the card slot and has a matching size.

[0011] Furthermore, friction plates are fixedly mounted on the outer walls of the two fixing plates on one side opposite to the other, and the telescopic spring is slidably connected between the two friction plates.

[0012] Furthermore, the cooling fan is located directly above the bare board of the switching power supply.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The heat dissipation type switching power supply bare board performs heat dissipation treatment on the top of the switching power supply bare board through a heat dissipation fan, and performs filtering treatment on the end of the heat dissipation fan through a dustproof net, thereby greatly reducing dust adhering to the fan blades. The dustproof net is installed through a rubber plate, a telescopic spring, a clamping rod and a clamping seat, so that the heat dissipation fan can be disassembled to clean the dust on its outer wall. At the same time, the bottom of the switching power supply bare board is heat-conducted through the functions of the support seat, the heat conduction plate and the heat dissipation fins, thereby improving the heat dissipation effect of the switching power supply bare board.
