Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation devices, and in particular relates to a novel power electronic heat dissipation device. Background Art

[0002] With the continuous development of power electronics technology, the requirements for heat dissipation devices are becoming higher and higher. Power electronic heat dissipation devices are developing towards a more efficient, more compact and more intelligent direction. For example, by adopting new heat dissipation materials, optimizing heat dissipation structures, introducing intelligent control technologies and other means, power electronic heat dissipation devices using intelligent control technology are an important product of the combination of power electronics technology and intelligent control technology.

[0003] This type of heat dissipation device using intelligent control technology not only has the basic functions of traditional heat dissipation devices, but also achieves precise regulation and optimization of the heat dissipation process through intelligent control technology, thereby improving heat dissipation efficiency and system stability. The intelligent control system can automatically adjust the speed of the cooling fan according to parameters such as the heat output of the equipment and the ambient temperature. When the equipment generates a lot of heat, the fan speed is automatically increased to improve heat dissipation efficiency; when the equipment generates less heat, the fan speed is automatically reduced to save power and reduce noise. Heat dissipation devices using intelligent control technology are used in many power electronic equipment, such as smart substations in smart grids and fiber optic boxes for weak current.

[0004] Common types of intelligent temperature-controlled fans for power electronics include DC variable-frequency intelligent temperature-controlled fans, thermistor-type intelligent temperature-controlled fans, intelligent temperature-controlled fans with remote monitoring and fault diagnosis functions, and intelligent temperature-controlled fan modules. Intelligent temperature-controlled fan modules are a conventional type of intelligent cooling fan that integrates temperature sensors, control circuits, and fan motors into a single module, achieving a highly integrated and modular design. They are widely used in various power electronic equipment, especially in situations where rapid deployment and replacement of cooling solutions are required.

[0005] When the intelligent temperature-controlled fan module is used for a long time, the fan may fail to start or the speed may be significantly lower than the normal level, affecting the heat dissipation effect. One of the reasons is excessive dust accumulation, which causes the fan bearing to wear or the fan blade to get stuck, affecting the fan speed, or improper installation, which causes vibration during use, resulting in unstable fan operation and noise, and even poor contact between components. The intelligent temperature-controlled fan module is generally fixed to the appropriate position of the power electronic equipment box with multiple screws to make it fit tightly with the box. However, in the case of slippage or vibration, the intelligent temperature-controlled fan module is prone to improper installation. In addition, during long-term use, dust accumulation at the heat dissipation port facing the cooling fan will affect heat dissipation. In addition, since the intelligent temperature-controlled fan module is close to the box, it cannot dissipate heat through the fan in time, which will also have an impact.

[0006] When installing the existing intelligent temperature-controlled fan module, there is a problem in the design that there is no limit on the position of the intelligent temperature-controlled fan module to prevent it from vibrating. Therefore, this application proposes a new power electronic heat dissipation device. Utility Model Content
