DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Please refer to Figures 1-6The convection cooling structure of the energy storage cabinet in this embodiment includes an energy storage cabinet 1, a power distribution controller 4, and multiple energy storage units 5. The energy storage cabinet 1 has a separate battery compartment 2 and a control cavity 3. The power distribution controller 4 is installed in the control cavity 3. Two support plates 6 are fixedly installed on the inner wall of the battery compartment 2. Multiple mounting holes 7 are opened on the side wall of the support plates 6. Multiple energy storage units 5 are respectively installed in multiple horizontal mounting holes 7 on the two support plates 6. A chiller 9 is installed on the upper surface of the energy storage cabinet 1. An air intake hood 10 is installed on one side of the energy storage cabinet 1. The space between the air intake hood 10 and the two support plates 6 is connected. The output end of the chiller 9 is connected to the air intake hood 10.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the convection cooling structure of the energy storage cabinet in this utility model is similar to that of existing energy storage cabinets, such as the prior art CN220731680U. The main improvement of this utility model is to improve the heat dissipation effect inside the energy storage cabinet and improve the uniformity of heat dissipation. In this utility model, the power distribution controller 4 located in the control cavity 3 controls and protects the energy storage unit 5. The energy storage unit 5 is supported by the mounting ports 7 on the two support plates 6. When multiple energy storage units 5 are installed between the two support plates 6, there is space between adjacent energy storage units 5. By starting the refrigeration unit 9, the refrigeration unit 9 delivers cold air to the air intake hood 10. The cold air blows into the energy storage cabinet 1 along the air intake hood 10. The cold air passes through the gaps between the energy storage units 5, thereby cooling the energy storage units 5. The heat dissipation effect of the energy storage units 5 is good and the heat dissipation of the energy storage units 5 is uniform, which improves the practicality.

[0028] The refrigeration unit 9 mentioned above can be purchased from the market. It is a mature technology that has been fully disclosed, so it will not be repeated in the instruction manual. The refrigeration unit 9 is equipped with a power connection cable, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power connection cable. The main controller can be a conventional known device such as a computer that plays a control role.

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, an exhaust hood 11 is installed on the side of the energy storage cabinet 1 away from the air intake hood 10. The space between the exhaust hood 11 and the two support plates 6 is connected. The exhaust hood 11 is connected to the air intake end of the refrigerator 9. An air intake unit 8 is installed on the upper side wall of the exhaust hood 11. The cold air blown from the air intake hood 10 to the energy storage cabinet 1 cools the energy storage unit 5. At the same time, the air intake end of the refrigerator 9 uses suction to work with the exhaust hood 11 to extract the hot air inside the energy storage cabinet 1. The hot air is cooled by the refrigerator 9 and then sent back to the energy storage cabinet 1, so that the air inside the energy storage cabinet 1 circulates and improves the heat dissipation effect.

[0030] like Figure 3 As shown, an air distribution plate 12 is fixedly connected to one end of the interior of the energy storage cabinet 1. The air distribution plate 12 is perpendicular to the support plate 6. Multiple air distribution holes 13 are opened on the side wall of the air distribution plate 12. The cold air blown out from the air inlet hood 10 is separated by the air distribution holes 13 on the air distribution plate 12, so that the cold air is blown to the energy storage unit 5 from multiple places, so that the energy storage unit 5 can dissipate heat evenly.

[0031] like Figure 4 As shown, multiple guide plates 14 are fixedly connected to the inner wall of the exhaust hood 11, and the multiple guide plates 14 are distributed at an incline. The exhaust hood 11 draws out the hot air in the energy storage cabinet 1, and the guide plates 14 guide the hot air to move upward and enter the refrigeration unit 9 through the exhaust hood 11 for cooling. By using the guide plates 14 to guide the hot air, the backflow of hot air into the energy storage cabinet 1 is reduced, thereby improving the heat dissipation effect.

[0032] like Figure 3 and Figure 6 As shown, the air intake unit 8 includes a mounting cover 81 that communicates with the upper side wall of the exhaust cover 11. The height of the mounting cover 81 is higher than the upper surface of the energy storage cabinet 1. Multiple fans 82 are installed on the inner wall of the mounting cover 81. The fans 82 are used to transport outside air into the exhaust cover 11, and the air blown out by the fans 82 drives the air inside the exhaust cover 11 to flow quickly. At the same time, the air blown in by the fans 82 can also reduce the heat of the gas transported out from inside the energy storage cabinet 1 with the exhaust cover 11, thereby reducing the energy consumption of the refrigerator 9.

[0033] like Figure 6 As shown, the air intake unit 8 also includes a baffle plate 84 installed on one side of the mounting cover 81. The side wall of the baffle plate 84 is provided with multiple filter holes 85. The baffle plate 84 is located outside the fan 82. When the fan 82 is working, the outside air is filtered through the filter holes 85 to prevent impurities and dust in the outside air from entering the refrigerator 9 and causing an impact.

[0034] like Figure 6As shown, the intake unit 8 also includes a mounting groove 83 on one side of the mounting cover 81. A baffle plate 84 is slidably connected in the mounting groove 83. The length of the baffle plate 84 is greater than the length of the mounting groove 83. A pull hole 86 is provided on one side wall of the baffle plate 84. The baffle plate 84 slides in the mounting groove 83. The pull hole 86 facilitates the sliding of the baffle plate 84 from the mounting groove 83, thereby facilitating the cleaning of the baffle plate 84.

[0035] The implementation steps in this embodiment are as follows: When it is necessary to dissipate heat inside the energy storage cabinet, the chiller 9 and fan 82 are started. The output end of the chiller 9 delivers cold air to the air intake hood 10. The cold air is blown into the energy storage cabinet 1 along the air intake hood 10. The cold air passes through the gaps between the energy storage units 5, thereby cooling the energy storage units 5. The air intake end of the chiller 9 uses suction to work with the exhaust hood 11 to extract the hot air inside the energy storage cabinet 1. The hot air is cooled by the chiller 9 and then delivered back into the energy storage cabinet 1. The fan 82 delivers outside air into the exhaust hood 11. The air blown out by the fan 82 drives the air inside the exhaust hood 11 to flow quickly. At the same time, the air blown in by the fan 82 can also reduce the heat of the gas delivered from inside the energy storage cabinet 1 to the outside along with the exhaust hood 11, thereby dissipating heat evenly on the energy storage units 5.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
