Description

Technical Field

[0001] The present application relates to the technical field of heat dissipation devices, and in particular to a double heat dissipation fan driven by a standard motor. Background Art

[0002] In the field of ventilation and cooling equipment technology, with the rapid development of industrialization, the heat dissipation demand of mechanical equipment is increasing. In the modern industrial production environment, how to achieve fast and efficient heat dissipation under high heat load conditions has become a key issue. This not only directly affects the working efficiency of the equipment, but also has an important impact on the stability and service life of the equipment. As the power density of electronic equipment continues to increase, efficient and reliable heat dissipation devices have become one of the key factors.

[0003] In the prior art, common heat dissipation methods mainly include fan cooling, liquid cooling and natural cooling. Among them, fan cooling has become one of the most widely used heat dissipation methods due to its low cost and easy use. However, the traditional single fan structure has many shortcomings, such as uneven heat dissipation and high noise. In order to solve these problems, the design of multi-fan collaborative work has gradually received attention. Although the multi-fan design can improve the heat dissipation performance to a certain extent, it still faces problems such as unreasonable air volume distribution and complex structure leading to inconvenient maintenance in actual applications.

[0004] Regarding the above-mentioned related technologies, the traditional direct connection method of the heat sink and the fan limits the heat dissipation effect and makes it difficult to fully utilize space resources. This structure not only has low heat dissipation efficiency, but also has defects such as unreasonable air duct layout and unoptimized heat dissipation component design. Therefore, it may lead to poor fan heat dissipation effect. Summary of the invention

The cleaned impurities slide into the collection box 534. When the impurities in the collection box 534 need to be cleaned, the collection box 534 can be separated from the cleaning frame 51.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
