Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0059] The heat dissipation device and energy storage cabinet according to some embodiments of the present application are described below with reference to Figures 1 to 22.

[0060] Example 1

[0061] 1 to 22 , an embodiment of the present application provides a heat dissipation device 10, comprising: an air guide member 1 and a heat dissipation member 2; wherein the air guide member 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;

[0063] According to the structure described above, it can be seen that the heat dissipation device 10 provided in the present application can be applied to an energy storage cabinet, and preferably, the energy storage cabinet also includes a cabinet 20, an air conditioner 30, a battery module 40 and the aforementioned heat dissipation device 10; wherein, the heat dissipation component 2 is arranged on the top of the battery module 40, and the air guide component 1 is arranged on the side of the battery module 40, the battery module 40 includes a battery column 401, and the number of heat dissipation components 2 is the same as the number of battery columns 401 and corresponds one to one; the air conditioner 30 is fixed to the outer wall of the cabinet 20, and the air guide inlet 15 of the air guide component 1 is connected to the air outlet of the air conditioner 30.

[0064] 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.

[0065] 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 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. In addition, 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 well cooled, the cooling effect is greatly improved, and thus helps to improve the thermal management efficiency. In addition, the structure of this device is simple and the cost is low.

[0066] In this embodiment, preferably, as shown in Figure 1, the heat dissipation device 10 also includes a sealing strip 7, and the sealing strip 7 is fixed at the relative connection between the air guide component 1 and the heat dissipation component 2. It should be noted that the relative connection here refers to the joint where the air guide component 1 and the heat dissipation component 2 are pressed against each other, and there is no connection relationship between the two.

[0067] According to the structure described above, the sealing strip 7 increases the sealing performance of the joint between the air guide component 1 and the heat dissipation component 2 .

[0068] 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 flanges and the second flanges is the same and corresponds one to one, the number of the sealing strips 7 is the same as the number of the first flanges and the number of the second flanges and corresponds one to one, and the sealing strips 7 are 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.

[0069] Furthermore, preferably, the air guide outlet 16 is square, and its four sides are provided with the aforementioned first flange. Correspondingly, the cooling air inlet 28 is also square, and its four sides are provided with the aforementioned second flange. Of course, the shapes of the air guide 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.

[0070] In this embodiment, preferably, as shown in FIG1 , the heat dissipation device 10 further includes a heat insulation layer 3 , and the inner and outer walls of the air guide channel 14 and the inner and outer walls of the heat dissipation component 2 are all attached with the heat insulation layer 3 .

[0071] According to the structure described above, the thermal insulation layer 3 is used to reduce the risk of condensation, and the position and number of the thermal insulation layer 3 are selected according to actual needs.

[0072] Furthermore, preferably, the heat insulation layer 3 can be fixed to the air guide channel 14 and the side wall of the heat dissipation component 2 by gluing.

[0073] In this embodiment, preferably, as shown in FIG22 , the air guide member 1 and the heat dissipation member 2 are detachably mounted on a target location, such as an outer wall of a front door of the cabinet 20 , by fastening members such as screws or bolts.

[0074] According to the structure described above, the air conditioner 30 is generally fixed on the outer wall of the front door of the cabinet 20, so the air guide member 1 can be fixed on the inner wall of the front door of the cabinet 20 through the fastening member, that is, the first fastening member 6, and the front door of the cabinet 20 is correspondingly provided with an avoidance opening. The above connection method is more flexible and convenient for installation and disassembly.

[0075] The heat dissipation component 2 can also be fixed to the cabinet 20 by fastening components such as screws or bolts (and preferably, the heat dissipation component 2 can also be fixed to the column of the cabinet 20 by fastening components such as screws or bolts), which is a detachable connection method, which is convenient for installation and disassembly. Preferably, as shown in Figures 1 and 10, the heat dissipation device 10 also includes a hanging ear, that is, a second hanging ear 4, and a second hanging ear 4 is provided on the heat dissipation component 2, and the second hanging ear 4 is formed with a mounting through hole, which is configured to install a bolt. For example, by installing a bolt in the mounting through hole, the second hanging ear 4 is detachably connected to other inner walls of the cabinet 20 that are not provided with a front door or structures such as brackets in the cabinet 20 by bolts. This is a detachable connection method, which is convenient for installation and disassembly.

[0076] According to the structure described above, the air conditioner 30 is generally fixed on the outer wall of the front door of the cabinet 20, and the air conditioner 30 can move as the front door is opened or closed. The heat dissipation component 2 can be fixed to other inner walls of the cabinet 20 where the front door is not provided or to structures such as columns in the cabinet 20 through the second hanging ear 4 thereon and with bolts. The heat dissipation component 2 always remains stationary. In the normal closed door state, the air guide component 1 is always in close contact with the heat dissipation component 2. Only when the door is open, the air guide component 1 is separated from the heat dissipation component 2. However, for most open door states, the energy storage cabinet 20 stops working. At this time, there is no need to cool the battery column 401, so there is no impact on the battery column 401. In addition, the above structure is convenient for later disassembly and maintenance.

[0077] Furthermore, preferably, the second hanging ear 4 may be in an L-shape, a Z-shape, a U-shape, etc. The shape may be selected according to actual needs.

[0078] Furthermore, preferably, the second hanging ear 4 on the heat dissipation component 2 can be connected to the heat dissipation component 2 by welding or bolts.

[0079] It should be noted that the connection method between the heat dissipation component 2 and the air guide component 1 and the cabinet 20 is not limited to the above-mentioned fastening components such as screws or bolts, and can also be connected by snap fastening or welding.

[0080] In this embodiment, preferably, as shown in Figure 10, along a preset direction, the air guide member 1 is arranged at one end of the heat dissipation member 2, and the cooling air outlet 29 is formed at the bottom of the other end of the heat dissipation member 2, and when the present device is installed on the top of the battery module 40, the side of the battery column 401 is directly below the cooling air outlet 29, that is, the cooling air outlet 29 is not blocked, and the outflowing cold air can flow along the side of the battery column 401 and continuously enter the gaps in the battery column 401 at different heights.

[0081] According to the structure described above, the air guide component 1 guides the cold air blown by the air conditioner 30 described below into the heat dissipation component 2. When the cold air passes through the heat dissipation component 2, it can cool the top of the battery column 401, and the cold air discharged through the heat dissipation component 2 can move downward along one side of the battery column 401, and then enter the battery gaps at different heights for cooling during the movement. The wind flows out to the other side through the battery column 401 and enters the air inlet of the air conditioner 30 to achieve circulation.

[0082] Furthermore, preferably, the aforementioned preset direction is the length direction of the heat dissipation component 2, that is, the same as the length direction of the battery column 401 corresponding thereto. Of course, it is not limited to this.

[0085] As can be seen from the structure described above, the heat dissipation member 2 also includes auxiliary air outlets and auxiliary air guide members 5 to quickly direct cool air into the battery array 401 below, further improving the heat dissipation effect and rate. Of course, this is not limited to this, and the design may also include only the cooling outlets 29 at the bottom for air discharge.

[0086] Furthermore, preferably, auxiliary air outlets are provided in the middle of one end of the heat dissipation component 2 away from the air guide component 1 and on both sides along the width direction of the heat dissipation component 2, and auxiliary air guide components 5 are provided.

It can be seen that this auxiliary air-guiding member 5 not only satisfies the air-guiding function, but also has a regular structure and is convenient for processing and manufacturing. Of course, it is not limited to this. The auxiliary air-guiding member 5 can also be a structure of other shapes, such as an L-shaped air guide duct structure, etc., which can be selected according to actual needs.

[0088] Furthermore, preferably, the contacting portions of the first top plate 51 and the four first side plates 52 may be connected by welding or the like.

[0089] In this embodiment, preferably, as shown in Figure 9, the cooling air inlet 28 of the heat dissipation component 2 is arranged at an angle downward toward the air guide outlet 16 of the air guide component 1, and the air guide outlet 16 is adapted to the cooling air inlet 28, so that the cold air blown in from the side and below can be quickly introduced into the cooling air inlet 28, thereby playing the role of guiding the air.

[0090] Furthermore, preferably, the heat dissipation component 2 includes a second top plate 21, a second bottom plate 22, a left side plate 23, a right side plate, a rear baffle 24, a front guide plate 25 and a front side plate 26; wherein the second top plate 21 and the second bottom plate 22 are spaced apart along the height direction of the heat dissipation component 2, the left side plate 23 and the right side plate are respectively arranged on opposite sides of the second top plate 21 and connected to the second top plate 21, and the left side plate 23 and the right side plate are respectively arranged on opposite sides of the second bottom plate 22 and connected to the second bottom plate 22, so as to enclose a shell structure with a hollow interior and open ends, and in a rectangular parallelepiped shape with a regular shape, which is convenient for processing and manufacturing as well as for later arrangement in the cabinet 20;

The front guide plate 25 is arranged downwardly and obliquely relative to the second top plate 21 and toward the air guide outlet 16 of the air guide member 1. The length of the second bottom plate 22 is shorter than the second top plate 21, so that the end of the second bottom plate 22 away from the air guide member 1 naturally forms the aforementioned cooling air outlet 29. Of course, the present invention is not limited to this, and the cooling air outlet 29 can also be provided on the second bottom plate 22.
