When the energy storage battery box is used for heat dissipation outdoors, if it encounters rain, snow or strong winds, rain and snow can easily enter the air inlet and outlet, which will cause a short circuit in the internal circuit of the battery.

[0030] See Figure 1-5 This is one embodiment of a heat dissipation structure for an outdoor energy storage battery according to the present invention.

[0031] The device includes an energy storage cabinet 1, in which multiple mounting plates 2 are vertically arranged, and multiple energy storage batteries 3 are horizontally mounted on the mounting plates 2. The energy storage cabinet 1 has through holes 4 on both sides, penetrating the inside and outside of the energy storage cabinet 1, and protective covers covering the through holes 4 are provided on the outside of both sides of the energy storage cabinet 1. The protective covers include an exhaust hood 5 and an intake hood 6 located on both sides of the energy storage cabinet 1. An exhaust pipe 7 is provided at the upper end of the exhaust hood 5, and an exhaust fan 8 is provided at one end of the exhaust pipe 7. An air inlet is provided at the lower end of the intake hood 6.

[0032] Outdoor energy storage batteries are generally installed in energy storage cabinet 1, so the heat dissipation structure for energy storage batteries is usually installed on energy storage cabinet 1. Specifically, through holes 4 are provided on both sides of energy storage cabinet 1, penetrating the inside and outside of energy storage cabinet 1. One through hole 4 is used to introduce cool air to balance the air pressure in energy storage cabinet 1, and the other through hole 4 is used to output hot air to dissipate heat from the energy storage battery.

[0033] An exhaust hood 5 covers one of the through holes 4, and an intake hood 6 covers the other through hole 4. An exhaust pipe 7 is provided at the upper end of the exhaust hood 5, and an air inlet is provided at the lower end of the intake hood 6. When heat dissipation is required, the exhaust fan 8 is started, and a negative pressure is formed in the entire exhaust system and the energy storage cabinet 1. External air enters from the air inlet at the lower end of the intake hood 6. The airflow passes through the internal space of the intake hood 6, then enters the energy storage cabinet 1 through the through hole 4, and then enters the exhaust hood 5 on the other side of the energy storage cabinet 1 through the through hole 4 on the other side. During this process, the airflow will carry away the hot air in the energy storage cabinet 1, thereby achieving heat dissipation of the energy storage cabinet 1. At the same time, the energy storage battery can also achieve heat dissipation by contacting the cold gas.

[0034] Finally, the gas in the exhaust hood 5 is extracted from the exhaust pipe 7 by the exhaust fan 8, completing the heat dissipation of the gas circulation.

[0035] When the cold air flows from one side of the energy storage cabinet 1 to the other side, due to the layout of the mounting plate 2 and the energy storage battery 3 in this device, the airflow can pass well from the top and bottom of the energy storage battery 3, carrying away the heat emitted by the energy storage battery 3.

[0036] Meanwhile, since this device is installed outdoors, it needs to be protected from rain, snow, hail and other weather conditions. If the through hole 4 is simply installed on the side of the energy storage cabinet 1, rain and snow will blow into the energy storage cabinet 1 through the through hole 4 in rainy or snowy weather, affecting the normal operation of the internal circuits and potentially causing a fire in severe cases. Therefore, this device has an air intake hood 6 and an air extraction hood 5 covering the through holes 4 on both sides.

[0037] The number of through holes 4 on each side of the energy storage cabinet 1 is thirty, and they are arranged vertically and evenly in groups of five; the interval between adjacent groups gradually decreases from the front end of the energy storage cabinet 1 to the rear.

[0038] The exhaust hood 5 is equipped with four vertical dividing plates 9, which divide the exhaust hood 5 into five transfer spaces 10. Each transfer space 10 is connected to a set of through holes 4, and the size of the transfer space 10 gradually decreases from the front end of the energy storage cabinet 1 to the rear. There are five exhaust pipes 7, which are connected to the transfer spaces 10 respectively.

[0039] Since the air extractor 8 in this device is located at the rear end of the energy storage cabinet 1, the air through hole 4 near the front end of the energy storage cabinet 1 is far from the air extractor 8; therefore, the airflow velocity of the through hole 4 near the air extractor 8 is faster than that of the through hole 4 far from the air extractor 8 during actual operation, which leads to an imbalance in the airflow velocity in the energy storage cabinet 1.

[0040] To ensure this balance, the device divides the exhaust hood 5 into five transfer spaces 10 by the partition plate 9. Each transfer space 10 is equipped with a separate exhaust pipe 7, and each transfer space 10 is connected to a set of vertical through holes 4. The size of the transfer spaces 10 gradually decreases from the front end of the energy storage cabinet 1 to the rear end. According to the formula of airflow velocity and area that can pass through per unit time, this setting can balance the airflow velocity in each transfer space 10 as much as possible, thus achieving a balance of airflow velocity in the energy storage cabinet 1.

[0041] An integrated pipe 11 is connected between the extraction pipe 7 and the extraction fan 8. The integrated pipe 11 is a segmented expanding pipe, and the diameter of the segmented expanding pipe gradually increases from the front end of the energy storage cabinet 1 to the rear.

[0042] In order to balance the airflow velocity in the integrated tube 11, the integrated tube 11 is set as a segmented diffuser tube, and the end diameter of the integrated tube 11 of the principle air pump 8 is the smallest.

[0043] An air intake frame 12 is provided at the lower end of the air extraction hood 5, and a filter screen is provided in the air intake frame 12.

[0044] The air intake frame 12 in this device is mainly used to change the direction of air intake of the exhaust hood 5, because the exhaust hood 5 facing the bottom is more likely to draw away humid air; the filter screen in this device is mainly used to filter out impurities in the air.

[0045] The overall shape of the dividing plate 9 is a right-angled triangle.

[0046] Meanwhile, due to the principle of hot air rising, most of the hot air in the energy storage cabinet 1 will be concentrated at the top. At this time, the working environment of the energy storage battery at the top is more severe than that of the energy storage battery at the bottom. Therefore, in order to balance the airflow of the exhaust, the transfer space 10 is set in the shape of a right triangle. Similarly, the cross-section of the pipe per unit time is used to measure the airflow velocity and flow rate. In this device, the cross-section at the bottom of the transfer space 10 is reduced to increase the airflow velocity entering through the bottom through hole 4.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
