Problems solved by technology

Regarding the heat dissipation technology of the PCB board, the commonly used methods are: 1) Paste the heat dissipation aluminum sheet on the power tube or the heating core. In the air, the space temperature is high, which affects the life of electronic devices, and at the same time, the production and assembly are not convenient; 2) Install cooling modules such as cooling fans or water-cooling tubes on the PCB. The disadvantage of this method is that installation is troublesome and the product cost is high.
[0003] To sum up, the traditional heat dissipation cannot solve the heat dissipation problem of some electronic devices on the PCB in a targeted manner. At the same time, there are complicated installation and high cost.

Description

technical field [0001] The invention relates to the field of PCB board circuits, in particular to a high-efficiency and low-cost PCB cooling device. Background technique [0002] In a PCB circuit containing heating components such as power tubes, magnetic core devices, and power resistors, the heat dissipation capability directly affects the maximum working environment temperature and product life of the product as a whole. Regarding the heat dissipation technology of the PCB board, the commonly used methods are: 1) Paste the heat dissipation aluminum sheet on the power tube or the heating core. In the air, the space temperature is high, which affects the life of electronic devices, and at the same time, production and assembly are not convenient; 2) Install cooling modules such as cooling fans or water-cooling tubes on the PCB. The disadvantage of this method is that installation is troublesome and the product cost is high. [0003] To sum up, the traditional heat dissipat...
