Description

Technical Field

[0001] This utility model relates to a DC energy storage cabinet, and more particularly to a wind-cooled DC energy storage cabinet. Background Technology

[0002] Currently, the biggest technical challenge facing new energy storage DC cabinets lies in heat dissipation. Specifically, batteries generate a large amount of heat during operation, and high outdoor temperatures exacerbate this heat accumulation. This heat can lead to a decrease in the battery's charge and discharge rate, thus affecting its normal operation. Therefore, heat dissipation has become a key issue that needs to be addressed in the design and operation of battery cabinets.

[0003] In existing technologies, some manufacturers choose to install fans on top of the battery cabinet for exhaust and heat dissipation. While this method is simple, its heat dissipation efficiency is low, and it is difficult to ensure temperature uniformity inside the battery cabinet. Other manufacturers have installed air conditioning for heat dissipation, but due to unreasonable design of the heat dissipation system, excessive local temperature differences occur, resulting in unsatisfactory heat dissipation.

[0004] Specifically, the main drawbacks of existing heat dissipation solutions are as follows: First, whether relying solely on fan exhaust or air conditioning for cooling, there is a lack of reasonable airflow design, making it difficult to achieve efficient heat transfer and dissipation, resulting in excessively high internal temperatures and low heat dissipation efficiency in the battery cabinet. Second, an unreasonable layout and configuration of the heat dissipation system can cause heat to accumulate inside the battery cabinet, failing to dissipate in time, thus affecting battery performance and lifespan. In addition, some manufacturers' heat dissipation solutions lack consideration for temperature uniformity, resulting in significant temperature differences in different areas inside the battery cabinet, which not only affects battery performance but may also pose safety hazards. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a wind-cooled heat storage DC cabinet that has a reasonable air duct design, can reduce local temperature difference, and can improve heat dissipation efficiency, in order to address the shortcomings of the existing technology.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0007] A wind-cooled heat dissipation and energy storage DC cabinet includes a cabinet body with multiple battery chambers inside. A cold air conditioner is provided on the front side of the cabinet body, and a vertically extending air guide cavity is provided on the rear side of the cabinet body. The cold air outlet of the cold air conditioner is connected to the air guide cavity. Multiple fans corresponding to each battery chamber are provided on the front side of the air guide cavity. The air inlet of each fan is connected to the air guide cavity, and the air outlet of each fan is connected to the rear end of the battery chamber. A return air chamber is provided on the front side of the cabinet body, and the front ends of the multiple battery chambers are all connected to the return air chamber. The return air outlet of the cold air conditioner is connected to the return air chamber.

[0008] Preferably, the upper end of the air guide cavity is formed with a transverse cavity extending laterally, the transverse cavity being close to the top of the cabinet, and the front end of the transverse cavity being connected to the cold air outlet of the air conditioner.

[0009] Preferably, the front end of the transverse cavity is provided with an air collecting hood, which is connected to the cold air outlet of the air conditioner.

[0010] Preferably, the width of the air guide cavity gradually decreases from top to bottom along the front-to-back direction.

[0011] Preferably, the cabinet includes a frame, and a front panel, a left panel, a right panel and a top panel are fixed to the outside of the frame.

[0012] Preferably, the air conditioner is fixed to the outside of the front panel.

[0013] Preferably, multiple battery cavities are distributed sequentially from top to bottom within the frame.

[0014] Preferably, a sealing strip is sandwiched between the front side panel and the frame.

[0015] Preferably, the rear sidewall of the air guide cavity is provided with a plurality of forward-bending bends from top to bottom.

[0016] The air-cooled heat dissipation and energy storage DC cabinet disclosed in this utility model has multiple battery chambers inside the cabinet, which are used to house batteries. The air conditioner and the air guide cavity are respectively located on the front and rear sides of the cabinet. The cold air generated by the air conditioner is delivered to the air guide cavity through the cold air outlet. When multiple fans are running, the cold air in the air guide cavity is delivered to the corresponding battery chamber, thereby dissipating heat from the batteries in the multiple battery chambers. The hot air formed after heat exchange with the batteries is then gathered in the return air chamber and returned to the return air vent of the air conditioner through the return air chamber, thus forming an airflow circulation. Compared with the prior art, this utility model, based on a reasonable air duct design, not only enables the batteries in the multiple battery chambers to exchange heat evenly and fully, but also effectively reduces the local temperature difference inside the cabinet and improves the heat dissipation efficiency.

[0019] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0020] It should be noted that the directional terms such as "front," "rear," "left," and "right" used in this utility model are only used to clearly describe the structure of this utility model and are not used to limit specific directions. That is, any directional adjustments made based on this utility model should also fall within the protection scope of this utility model.

[0021] This utility model discloses a wind-cooled heat dissipation and energy storage DC cabinet, combined with Figures 1 to 2 As shown, it includes a cabinet 1, which contains multiple battery chambers 10. A cooling air conditioner 2 is located on the front side of the cabinet 1, and a vertically extending air guide cavity 3 is located on the rear side of the cabinet 1. The cooling air outlet of the cooling air conditioner 2 is connected to the air guide cavity 3. Multiple fans 30, corresponding one-to-one with each battery chamber 10, are located on the front side of the air guide cavity 3. The air inlet of each fan 30 is connected to the air guide cavity 3, and the air outlet of each fan 30 is connected to the rear end of each battery chamber 10. A return air chamber 11 is located on the front side of the cabinet 1, and the front ends of the multiple battery chambers 10 are all connected to the return air chamber 11. The return air outlet of the cooling air conditioner 2 is connected to the return air chamber 11.

[0022] In the above structure, the cabinet 1 has multiple battery chambers 10, which are used to house batteries. The air conditioner 2 and the air guide chamber 3 are respectively located on the front and rear sides of the cabinet 1. The cold air generated by the air conditioner 2 is delivered to the air guide chamber 3 through the cold air outlet. When multiple fans 30 are running, the cold air in the air guide chamber 3 is delivered to the corresponding battery chamber 10, thereby dissipating heat from the batteries in the multiple battery chambers 10. The hot air formed after heat exchange with the batteries is then gathered in the return air chamber 11 and returned to the return air vent of the air conditioner 2 through the return air chamber 11, thus forming an airflow circulation. Compared with the prior art, this utility model, based on a reasonable air duct design, not only enables the batteries in the multiple battery chambers 10 to exchange heat evenly and fully, but also effectively reduces the local temperature difference in the cabinet and improves the heat dissipation efficiency.

[0023] In this embodiment, the air guide cavity 3 is preferably an "L"-shaped cavity. Please refer to [link / reference]. Figure 1 and Figure 2 The upper end of the air guide cavity 3 is formed with a transverse cavity 31 extending laterally. The transverse cavity 31 is close to the top of the cabinet 1, and the front end of the transverse cavity 31 is connected to the cold air outlet of the air conditioner 2.

[0024] In the above structure, the transverse cavity 31 is formed at the upper end of the air guide cavity 3 and extends to the front side of the cabinet 1, which facilitates connecting the front end of the transverse cavity 31 to the cold air outlet of the air conditioner 2. At the same time, based on the integrated structural design of the transverse cavity 31 and the air guide cavity 3, it is easy to process and manufacture and convenient to install.

[0025] In order to more fully incorporate the cold air delivered by the air conditioner 2, in this embodiment, the front end of the transverse cavity 31 is provided with an air collecting hood 32, which is connected to the cold air outlet of the air conditioner 2.

[0026] As a preferred embodiment, the width of the air guide cavity 3 gradually decreases from top to bottom along the front-to-back direction. To achieve the above structure, in this embodiment, the rear sidewall of the air guide cavity 3 is provided with a plurality of forward-bending bends 33 from top to bottom. Specifically, the bends 33 are Z-shaped bends, thereby making the rear sidewall of the air guide cavity 3 stepped.

[0027] Please see Figure 1 and Figure 2 In this embodiment, the volume of the internal cavity of the air guide cavity 3 gradually decreases from top to bottom. The advantage of this structure is that the cold air gradually gathers as it is transported downward in the air guide cavity 3, which enables the fan 30 near the bottom to fully draw in the cold air.

[0028] For the preferred structure of the cabinet 1, please refer to [link / reference]. Figure 1 The cabinet 1 includes a frame 12, and a front side panel 13, a left side panel 14, a right side panel 15 and a top panel 16 are fixed to the outside of the frame 12.

[0029] Furthermore, the air conditioner 2 is fixed to the outside of the front panel 13. Multiple battery compartments 10 are distributed sequentially from top to bottom within the frame 12.

[0030] In order to provide a sealing effect on the front side, in this embodiment, a sealing strip 17 is sandwiched between the front side plate 13 and the frame 12.

[0031] The air-cooled heat dissipation and energy storage DC cabinet disclosed in this utility model uses air conditioning for cooling, which is the basis of the heat dissipation solution. On this basis, this utility model has rationally designed the air duct to optimize the distribution and flow of cold air. The air duct is stepped, and this unique design ensures that the cold air can be evenly distributed to the rear of each battery box, which not only improves the utilization rate of cold air, but also ensures that heat exchange is fully carried out in each battery box.

[0032] When the cold air reaches the rear of the battery box through the air duct, the fans on the front panel of the battery box start to function. These fans draw the cold air into the box and then blow it out from the front panel. In this process, the cold air effectively removes the heat from the battery inside the box, achieving rapid cooling of the battery box. This circulating airflow path formed from back to front in this embodiment greatly improves heat dissipation efficiency.

[0033] In practical applications, based on the above-mentioned air duct design, this application can concentrate and precisely guide the cold air to the battery box. At the same time, the air duct adopts a stepped design, which can ensure that each battery box can obtain a uniformly distributed cold air and realize the smooth flow of cold air in the air duct, avoiding the occurrence of uneven wind speed or eddy phenomena, thereby improving the uniformity and efficiency of heat dissipation.

[0034] Meanwhile, this embodiment adopts a wall-mounted air conditioner and front door design. This installation method not only saves space, but also allows the air conditioner's cold air to blow directly into the air duct. The front door is designed with four hinges, which not only enhance the door's strength, but also ensure that the door can fit tightly when closed to prevent cold air leakage. When the door is closed, the air conditioner's cold air outlet is tightly connected to the air duct's air inlet, forming a closed heat dissipation system that efficiently delivers cold air to each battery compartment.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
