Description

[0002] At present, the large-capacity energy storage cabinets on the market are relatively large in size and weight, which makes them inconvenient to move indoors. In addition, the heat dissipation system often adopts air cooling or liquid cooling. This traditional single heat dissipation method has certain limitations, and most energy storage cabinets adopt a left and right structural layout, that is, the battery pack and other electrical equipment are placed on the left and right ends of the energy storage cabinet respectively. This structure further reduces the working efficiency of the heat dissipation system. In view of the shortcomings of existing energy storage cabinets such as inconvenient movement, single heat dissipation method, and low efficiency, in order to solve the above problems, it is urgent to develop a new energy storage cabinet using composite heat dissipation technology, which has the characteristics of easy movement, better structure, high heat dissipation efficiency, and low energy consumption.

[0043] Example 5

[0044] The difference between the structure disclosed in this embodiment and that disclosed in Embodiment 4 is that this embodiment further describes the structure of the base 100 .

[0045] Specifically, Figure 2 and 5As shown, the base 100 includes a covering steel plate 101 and a plurality of rectangular bases 102, a square tube 103 and a limiting steel plate 104; the covering steel plate 101 is fixedly connected to the bottom of the energy storage cabinet shell 300, and a plurality of rectangular bases 102 are fixedly installed in parallel on the lower surface of the covering steel plate 101, and the square tube 103 and the limiting steel plate 104 are fixed between two adjacent groups of rectangular bases 102, which can enhance the lateral rigidity of the base and prevent it from slipping during transportation.

[0046] In this embodiment, two groups of foldable moving mechanisms 105 are further provided below the base 100, and the foldable moving mechanisms 105 are fixedly connected to the square tube 103 by screws. The foldable moving mechanisms 105 include an axle seat 105a, an optical axis 105b, a caster seat 105c, a heavy-duty caster 105d, and a limiting device; the axle seat 105a is fixedly mounted on the bottom of the square tube 103, and the optical axis 105b is fixedly connected to the axle seat 105a; the caster seat 105c is rotatably mounted on the optical axis 105b, and the heavy-duty caster 105d and the limiting device are fixedly mounted on the caster seat 105c.

[0047] When the device needs to be moved, the caster seat 105c is flipped downward along the optical axis 105b so that the heavy-loaded caster 105d touches the ground, and then the caster seat 105c is locked and fixed by the limit seat 105e and the limit pin (105f). When the moving operation is completed, the limit pin (105f) is removed, and the caster seat 105c is flipped upward along the optical axis 105b so that the heavy-loaded caster 105d leaves the ground, and the caster seat 105c is locked and fixed again by the limit pin (105f).

[0048] During use, when liquid cooling is performed, two liquid coolers 208 arranged in the middle of the energy storage rack 201 transport the coolant 207 to the battery cells 202 on the left and right sides through liquid cooling pipes. After heat exchange, the heat generated by its operation is absorbed and returned to the liquid cooler 208 for re-cooling. The cooled coolant is then transported to the battery cells 202 to absorb heat. This cycle is repeated to achieve the effect of liquid cooling. When air cooling is performed, the fan 206 continuously transports cold air from the bottom louvers into the cabinet. The designed air duct takes away the heat generated by the operation of the equipment in the cabinet, and the hot air with lighter density is continuously discharged out of the cabinet through the louvers reserved at the top. This cycle is repeated to achieve the effect of air cooling. The two can also be flexibly switched or work together according to different working conditions to improve the heat dissipation efficiency and reduce the operating energy consumption.

[0049] The above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
