Description

Technical Field

[0001] The utility model relates to the field of industrial equipment, and particularly relates to a fan convenient for heat dissipation. Background Art

[0002] In modern electronic devices, as a core component, the electronic control board undertakes multiple functions such as driving, controlling, and energy conversion. Its stability and reliability are directly related to the performance of the entire system. However, with the improvement of the integration degree of electronic components and the increase of power density, the main heat sources on the electronic control board, namely IPM (Intelligent Power Module, hereinafter simply referred to as power module) and rectifier bridge, generate rapidly increasing heat during operation, posing an unprecedented challenge to the heat dissipation design. As the "heart" of the electronic control system, the power module integrates multiple functions such as driving, protection, and power conversion. The high power density design inside it makes a large amount of heat energy released while working efficiently. And the rectifier bridge, as a key link in the electric energy conversion, under the working conditions of high current and high voltage, components such as diodes will also generate significant heat. The dispersed layout of these two major heat sources on the electronic control board makes it difficult to effectively concentrate the heat and quickly discharge it through the heat dissipation system. On the one hand, due to the dispersion of the heat sources, it is difficult to achieve centralized heat treatment, resulting in low heat dissipation efficiency; on the other hand, the complexity of the heat dissipation path and the limitations of the heat dissipation materials also further limit the improvement of the heat dissipation effect. In a high-temperature environment, the internal temperature of the electronic control board rises rapidly, easily exceeding the temperature tolerance limit of the components, which not only affects the performance and lifespan of the components, but also may cause system failures, increasing the maintenance cost and downtime.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above defects. Summary of the Utility Model
