Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and more specifically to an air conditioning heat dissipation structure for an energy storage cabinet. Background Technology

[0002] Chinese utility model patent with publication number CN202322843739.6 discloses an air-cooled heat dissipation structure for an energy storage cabinet. It achieves air-cooled heat dissipation by setting up components such as an industrial air conditioner, an air guide shroud, an air supply duct, a return air duct, and an air distribution plate. The air is delivered to the battery cluster area through the air guide shroud and the air supply duct, reducing the temperature difference of the battery cells and improving the heat dissipation effect.

[0003] However, the aforementioned patents also have many limitations. The layout of the air supply and return ducts will result in high air resistance due to bending and changes in cross-sectional area, which will affect the heat dissipation efficiency. Furthermore, the installation of a fan at the front end of the battery module will generate additional heat and energy consumption during operation, which will affect energy utilization efficiency and heat dissipation burden.

[0004] In addition, existing energy storage cabinets generally lack heat insulation measures against the external environment. The heat from the external environment can also easily interfere with the temperature inside the energy storage cabinet, making it difficult for the batteries and electrical equipment inside the cabinet to maintain a stable operating temperature. Especially in high-temperature environments, this may affect their normal operation and reduce the safety of the energy storage cabinet. Utility Model Content

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1-3This utility model discloses an air conditioning heat dissipation structure for an energy storage cabinet, including an inner frame 1, an outer panel 2, and a cabinet door 3. The inner frame 1 is divided into a battery area 4 and an electrical area 5. The key feature is that a heat insulation layer 10 is provided between the inner frame 1 and the outer panel 2. The heat insulation layer 10 between the inner frame 1 and the outer panel 2 can effectively block the influence of the external ambient temperature on the cabinet and maintain the relative stability of the internal temperature. The heat insulation layer is made of rock wool, which has a low thermal conductivity and can effectively reduce heat transfer, thus helping to improve the stability and safety of the energy storage cabinet operation.

[0024] like Figures 2-5 As shown, the battery area 4 is equipped with several racks 40; the electrical area 5 is equipped with an exhaust fan 30 and an air supply duct 51; and an air conditioner 50 is installed on the cabinet door 3. The air conditioner 50 is connected to the air supply duct 51, with the tail end of the air supply duct 51 positioned at the top of the battery area 4. Installing the air conditioner 50 on the cabinet door 3 facilitates installation and maintenance. The air conditioner 50, in conjunction with the air supply duct 51, allows for effective delivery of cool air into the energy storage cabinet. Furthermore, the electrical area 5 is equipped with a temperature sensor 503. Based on the feedback from the temperature sensor 503, the air conditioner 50 automatically adjusts its cooling power and fan speed, flexibly adjusting the cooling effect according to the actual temperature. This ensures effective heat dissipation while saving energy and improving the intelligence level of the energy storage cabinet's operation.

[0025] Reference Figure 3 , Figure 4 , Figure 6 The battery area 4 is equipped with a baffle plate 401 at the top and air guide plates 101 on both sides of the top of the battery area 4. The air guide plates 101 are connected to the inner frame 1 of the cabinet to form a cold air channel 110 with an opening at the bottom. Ventilation holes 404 are arranged on the front and sides of the cold air channel 110 according to the setting position of the placement rack 40. After the battery modules are arranged in an orderly manner by the placement rack 40, the air blown out by the baffle plate 401, air guide plates 101 and the inner frame 1 of the cabinet through the ventilation holes on the front and sides can fully cover the batteries in the battery area and the components in the electrical area, effectively improving the heat dissipation efficiency, ensuring that the batteries work in a suitable temperature environment, and extending the battery life. Since hot air has a relatively low density, it will naturally float upward. At this time, the exhaust fan 30 set on the top side of the electrical area 5 starts to work to extract the hot air accumulated at the top of the energy storage cabinet.

[0026] like Figure 1 , Figure 3As shown, the electrical area 5 is equipped with an air conditioning unit 501, and both the air conditioning unit 501 and the cabinet door 3 are equipped with air conditioning water outlets 502. The air conditioning water outlet pipe inside the energy storage cabinet is concealed, which not only allows staff to drain water directly from outside the cabinet door, but also prevents short circuits caused by condensate, ensuring electrical safety. Furthermore, it does not affect the appearance of the energy storage cabinet and does not occupy extra space. The cabinet door is also equipped with an emergency stop device 6. In the event of an abnormality inside the energy storage cabinet, the operator can quickly cut off the power supply to the energy storage cabinet using the emergency stop device.

[0027] Working Principle: After the air conditioner 50 is started, cold air is delivered to the top of the battery area 4 through the air supply duct 51. Due to the baffle 401 at the top, the cold air cannot flow directly or downwards, but instead flows along the cold air channels 110 formed by the air guide plates 101 and the inner frame 1 of the cabinet on both sides. Ventilation holes 404 are provided on the front and sides of the cold air channels 110 according to the position of the mounting rack 40. The cold air is then blown out from the ventilation holes 404. The front holes evenly cover the batteries in the battery area 4, while the side holes cover the components in the electrical area 5, thus achieving efficient heat dissipation. The hot air generated by the equipment operation naturally rises due to density differences. The exhaust fan 30 located at the top side draws out the hot air, accelerating air circulation. In this way, the cold air flows systematically within the energy storage cabinet, ensuring that the temperature in each area is maintained within a suitable range and guaranteeing the stable operation of the energy storage cabinet.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
