[0002] Existing battery performance testing equipment commonly suffers from internal dust accumulation, excessive heat generation, and excessive noise during long-term operation. Dust buildup affects the equipment's heat dissipation efficiency, leading to increased component temperatures and consequently reducing the accuracy of test data and the equipment's lifespan.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Reference Figures 1 to 4A heat dissipation, noise reduction, and dust prevention system according to a first aspect of this utility model includes a housing 100. A filter layer 111, a noise reduction layer 112, and a heat dissipation layer 113, arranged sequentially from the outside to the inside, are installed within at least two side walls of the housing 100 to simultaneously achieve dust prevention, noise reduction, and heat dissipation functions, thereby improving the stability of equipment operation and the accuracy of testing. The remaining side walls of the housing 100 are equipped with heat dissipation layers 113 to improve the heat dissipation effect on the equipment inside the housing 100. The side walls of the housing 100 are provided with multiple mounting slots 115, in which the filter layer 111, noise reduction layer 112, and heat dissipation layer 113 are detachably installed for easy disassembly, cleaning, or maintenance. The heat dissipation layer 113 has an aluminum alloy fiber mesh 114. Aluminum alloy has excellent thermal conductivity, and the fibrous aluminum alloy material increases the contact area with air, thereby improving the heat dissipation effect. The noise reduction layer 112 is made of a mixture of polyester fiber cotton and mineral wool, which can effectively absorb noise and vibration, reducing environmental noise. The filter layer 111 contains sponge-like activated carbon, which adsorbs impurities and prevents dust from entering the housing 100.

[0024] Understandably, the filter layer 111 uses sponge-like activated carbon material. This sponge-like activated carbon material is an air purification filter material made by attaching high-quality, highly absorbent powdered catalytic activated carbon to a polyurethane foam carrier using a polymer binder. It has a high specific surface area and porous structure, effectively adsorbing dust and impurities and preventing them from entering the housing 100. The noise reduction layer 112 is made of a mixture of polyester fiber cotton and mineral wool. Through multiple reflections and absorptions of sound waves and the resonance effect, it significantly reduces the noise during equipment operation. In this embodiment, the noise reduction layer 112 is made of a mixture of 30% polyester fiber and 70% mineral wool. The heat dissipation layer 113 is an aluminum alloy fiber mesh 114. Aluminum alloy has excellent thermal conductivity, and the fibrous structure increases the contact area with air, thereby improving heat dissipation efficiency.

[0025] It is understood that the outer perimeter of the enclosure 100 includes four side walls, namely the first side wall 101, the second side wall 102, the third side wall 103 and the fourth side wall 104. The first side wall 101 and the second side wall 102 are arranged opposite each other along the first direction, and the third side wall 103 and the fourth side wall 104 are arranged opposite each other along the second direction. The first side wall 101 and the second side wall 102 are equipped with a filter layer 111, a noise reduction layer 112 and a heat dissipation layer 113, and the third side wall 103 and the fourth side wall 104 are equipped with a heat dissipation layer 113. This design not only ensures the requirements of dust prevention and noise reduction, but also improves the overall heat dissipation effect through multi-directional heat dissipation.

[0026] Furthermore, the first sidewall 101 and the second sidewall 102 have hinged door panels 110. A filter layer 111, a noise reduction layer 112, and a heat dissipation layer 113 are installed inside the door panel 110. The frame 117 of the door panel 110 has an opening at the top, allowing the filter layer 111, noise reduction layer 112, and heat dissipation layer 113 to be inserted from top to bottom into mounting slots 115 within the frame 117. This simplifies operation and allows users to easily open the door panel 110 for internal equipment maintenance or material replacement. Simultaneously, the third sidewall 103 and the fourth sidewall 104 have vertically extending slots 119. These slots 119 have openings at the top of the housing 100, and the heat dissipation layer 113 is installed in them. The heat dissipation layer 113 can be inserted from top to bottom, simplifying the installation process while ensuring the stability of the heat dissipation layer 113.

[0027] Reference Figure 3 The heat dissipation layer 113 is composed of at least three layers of aluminum alloy fiber mesh 114, with a gap 118 between adjacent layers. The width of the gap 118 is controlled within a reasonable range to optimize airflow and heat dissipation. In this embodiment, the width of the gap 118 is S1, satisfying: 0.15mm ≤ S1 ≤ 0.25mm. It is understood that when the width of the gap 118, S1 < 0.15mm, is too small, insufficient air enters the gap 118 from the outside, resulting in insufficient airflow efficiency and a small contact area between the aluminum alloy fiber mesh 114 and the air, thus reducing the heat dissipation effect. When the width of the gap 118, S1 > 0.25mm, although the airflow increases, the excessively large gap 118 leads to a longer heat conduction path between the aluminum alloy fiber mesh 114, preventing efficient heat transfer between adjacent layers and reducing the overall heat dissipation efficiency. Meanwhile, an excessively large gap 118 will reduce the stacking density of the multi-layer aluminum alloy fiber mesh 114, resulting in a decrease in the effective heat dissipation area per unit area and affecting the optimal performance of heat dissipation. Furthermore, an excessively large gap 118 may also cause structural stability issues. When the equipment vibrates or is impacted, relative displacement can easily occur between adjacent aluminum alloy fiber meshes 114, thus affecting long-term reliability. Therefore, only when the width S1 of the gap 118 satisfies the condition of 0.15mm ≤ S1 ≤ 0.25mm can good heat dissipation be ensured and a stable installation structure for the aluminum alloy fiber mesh 114 be guaranteed. In this embodiment, the preferred width S1 of the gap 118 is 2mm.

[0028] In this embodiment, the aluminum alloy fiber mesh 114 has a fiber diameter of 60 μm, a length of 3 mm, a single-layer thickness of 1.5 mm, and a total thickness of 5 mm after multiple layers are stacked. This structure not only improves heat dissipation efficiency but also forms convective heat dissipation through the gaps between the fibers, while utilizing the high thermal conductivity of aluminum alloy to achieve rapid heat conduction. Meanwhile, the noise reduction layer 112 has a thickness of 50 mm, and the filter layer 111 has a thickness of 20 mm. A partition 116 is provided between the filter layer 111 and the noise reduction layer 112, and between the noise reduction layer 112 and the heat dissipation layer 113. Multiple through holes are formed on the partition 116 to ensure airflow without weakening the noise reduction effect.

[0029] In a second aspect of this utility model, a battery testing device is provided, including the aforementioned heat dissipation, noise reduction, and dust prevention system. It is understood that the battery testing device possesses all the technical features of the heat dissipation, noise reduction, and dust prevention system; therefore, the battery testing device at least possesses all the beneficial effects of the heat dissipation, noise reduction, and dust prevention system.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
