[0057] Refer to the following Figures 1 to 22 The heat dissipation device and energy storage cabinet according to some embodiments of the present application are described.

[0058] Embodiment 1

[0059] See also Figures 1 to 22 As shown, an embodiment of the present application provides a heat dissipation device 10, comprising: an air guide component 1 and a heat dissipation component 2; wherein the air guide component 1 is formed with an air guide channel 14 and an air guide inlet 15 and an air guide outlet 16 respectively connected to the air guide channel 14;

[0062] In combination with the above, the process of cooling the battery module 40 by the heat dissipation device 10 provided in the present application is as follows: the air guide component 1 guides the cold air blown by the air conditioner 30 into the heat dissipation component 2, and the cold air can cool the top of the battery column 401 when passing through the heat dissipation component 2, and the cold air discharged through the heat dissipation component 2 can move downward along the side of the battery column 401, so that the cold air enters the battery gaps at different heights for cooling during the movement, and the wind flowing out through the battery column 401 enters the air inlet of the air conditioner 30 to achieve circulating cooling.

[0063] It can be seen that the heat dissipation device 10 provided in the present application separates the inherent cooling air duct in the original energy storage cabinet, and then the heat dissipation components 2 can be increased or decreased according to the actual number of battery columns 401, that is, the heat dissipation channel can be adaptively adjusted according to the actual number of battery columns 401, and the cold air blown out by the air conditioner 30 is reasonably distributed to each heat dissipation component 2 through the air guide component 1, so that each battery column 401 can be better cooled, the cooling effect is greatly improved, and then it helps to improve the thermal management efficiency, and the structure of the device is simple and the cost is low.

[0065] According to the structure described above, it can be known that the sealing strip 7 increases the sealing performance of the joint between the air guide component 1 and the heat dissipation component 2 .

[0066] Further, preferably, a first flange is formed on each side of the end of the air guide component 1 close to the heat dissipation component 2, that is, the air guide outlet 16, and a second flange is formed on each side of the end of the heat dissipation component 2 close to the air guide component 1, that is, the cooling air inlet 28 of the heat dissipation component 2, and the number of the first flange and the second flange are the same and correspond one to one, the number of the sealing strips 7 is the same as the number of the first flange and the number of the second flange and corresponds one to one, and the sealing strip 7 is fixed on the first flange or the second flange, and the first flange and the second flange can compress the sealing strip to achieve sealing.

[0067] Furthermore, preferably, the air outlet 16 is square, and its four sides are all provided with the aforementioned first flange. Correspondingly, the cooling air inlet 28 is also square, and its four sides are all provided with the aforementioned second flange. Of course, the shapes of the air outlet 16 and the cooling air inlet 28 are not limited to the above, and can also be selected according to actual needs, such as a triangle or a polygon with more than four such as a pentagon or hexagon, or even a circle, etc.

[0068] In this embodiment, preferably, Figure 1 As shown, the heat dissipation device 10 further includes a heat insulation layer 3 , and the inner wall and outer wall of the air guide channel 14 and the inner wall and outer wall of the heat dissipation component 2 are all attached with the heat insulation layer 3 .

The above connection method is more flexible and easy to install and disassemble.
