[0044] Specifically, this utility model provides an energy storage cabinet that can be used to store batteries.

[0045] like Figure 1 As shown, the energy storage cabinet of this utility model includes a cabinet body 1 and a liquid cooling plate 2, which is installed inside the cabinet body 1. The battery 3 is placed on the liquid cooling plate 2, and the liquid cooling plate 2 cools the battery 3.

[0046] It should be noted that, in addition to the cabinet body 1 and the liquid cooling plate 2 mentioned above, the energy storage cabinet of this utility model also includes a liquid supply pipeline, a circulation pump and a liquid supply device. The liquid supply pipeline connects the liquid cooling plate 2 and the liquid supply device. The liquid supply device is used to provide coolant to the liquid cooling plate 2.

[0047] It should be noted that this utility model does not limit the specific structure of the liquid supply device, and the energy storage cabinet of this utility model can adopt any liquid supply device in the prior art.

[0048] Preferably, such as Figure 1 to Figure 4 As shown, the liquid cooling plate 2 of this utility model has a liquid inlet 21, a liquid outlet 22, a liquid inlet channel 23, a liquid return channel 24, and multiple cooling zones distributed along its length, each cooling zone being capable of holding at least one battery 3.

[0049] For example, such as Figure 1 and Figure 2 As shown, the liquid cooling plate 2 has 5 cooling zones, which are located along the length of the liquid cooling plate 2 (from... Figure 2 The distribution (viewed from above in the Y direction) allows for the placement of one battery 3 on each cooling zone, and five batteries 3 can be placed on a single liquid cooling plate 2.

[0050] It should be noted that the number of cooling zones on the liquid cooling plate 2 is not limited to the above-mentioned 5, for example, it can also be 3, 4, 6 or more, and those skilled in the art can flexibly set the specific number of cooling zones according to the length of the liquid cooling plate 2 and the size of the battery 3 in actual application.

[0051] As shown in Figure 2 to Figure 4 , the liquid inlet flow channel 23 on the liquid cooling plate 2 extends along the length direction of the liquid cooling plate 2 and communicates with the liquid inlet 21, the liquid return flow channel 24 on the liquid cooling plate 2 extends along the length direction of the liquid cooling plate 2 and communicates with the liquid outlet 22, and the liquid inlet flow channel 23 and the liquid return flow channel 24 are located on the same side of the liquid cooling plate 2 in the width direction.

[0052] Exemplarily, as shown in Figure 2 to Figure 4 , the liquid inlet flow channel 23 and the liquid return flow channel 24 are both arranged on the right side of the liquid cooling plate 2, the liquid inlet flow channel 23 extends from one end of the length direction of the liquid cooling plate 2 to the other end of the liquid cooling plate 2, one end of the liquid inlet flow channel 23 communicates with the liquid inlet 21 on the liquid cooling plate 2, and the liquid return flow channel 24 also extends from one end of the length direction of the liquid cooling plate 2 to the other end of the liquid cooling plate 2, one end of the liquid return flow channel 24 communicates with the liquid outlet 22 on the liquid cooling plate 2.

[0053] It should be noted that the liquid inlet 21 and the liquid outlet 22 are not limited to being arranged at the ends of the length direction of the liquid cooling plate 2, for example, those skilled in the art can also arrange the liquid inlet 21 and the liquid outlet 22 close to the middle position of the length direction of the liquid cooling plate 2 in actual application, that is, the middle position of the length direction of the liquid inlet flow channel 23 communicates with the liquid inlet 21, and the middle position of the length direction of the liquid return flow channel 24 communicates with the liquid outlet 22.

[0054] As shown in Figure 2 to Figure 4 , the cooling zone on the liquid cooling plate 2 has a first cooling flow channel 25 and a second cooling flow channel 26 distributed along the length direction of the liquid cooling plate 2, the first cooling flow channel 25 extends along the width direction of the liquid cooling plate 2, and one end of the first cooling flow channel 25 communicates with the liquid inlet flow channel 23, the second cooling flow channel 26 extends along the width direction of the liquid cooling plate 2, and one end of the second cooling flow channel 26 communicates with the liquid return flow channel 24, the other end of the first cooling flow channel 25 communicates with the other end of the second cooling flow channel 26, and the flow direction of the liquid in the first cooling flow channel 25 is opposite to the flow direction of the liquid in the second cooling flow channel 26.

[0055] Exemplarily, as shown in Figure 2 to Figure 4 , the liquid cooling plate 2 is provided with the first cooling flow channel 25 and the second cooling flow channel 26 at the position corresponding to each cooling zone, the first cooling flow channel 25 and the second cooling flow channel 26 are distributed along the length direction (Y direction as viewed from Figure 2 above) of the liquid cooling plate 2, and the first cooling flow channel 25 and the second cooling flow channel 26 both extend from one side to the other side of the width direction of the liquid cooling plate 2, and the first cooling flow channel 25 and the second cooling flow channel 26 are arranged on the same side of the liquid cooling plate 2 in the width direction.Figure 2 Viewed from above, extending along the X direction, the right end of the first cooling channel 25 is connected to the liquid inlet channel 23, the right end of the second cooling channel 26 is connected to the liquid return channel 24, and the left end of the first cooling channel 25 is connected to the left end of the second cooling channel 26.

[0056] like Figure 2 As shown in the diagram, the arrows indicate the flow direction of the coolant. The coolant enters through the inlet 21 on the liquid cooling plate 2 and flows along the inlet channel 23 within the liquid cooling plate 2. Figure 2 Viewed from above, the coolant flows upward along the Y direction. As it flows through each cooling zone, the coolant enters the first cooling channel 25 from the inlet channel 23, and then flows along the first cooling channel 25. Figure 2 Viewed from above, the coolant flows to the left along the X direction. After flowing to the left side of the liquid cooling plate 2, the coolant enters the second cooling channel 26 and then flows along the second cooling channel 26. Figure 2 Viewed from above, the coolant flows to the right along the X direction. After flowing to the right side of the liquid cooling plate 2, it enters the return channel 24 and then flows along the return channel 24. Figure 2 Viewed from above, the liquid flows downwards along the Y direction and finally exits from the outlet 22 on the liquid cooling plate 2.

[0057] In other words, the liquid inlet channel 23 and the liquid return channel 24 on the liquid cooling plate 2 run through multiple cooling zones on the liquid cooling plate 2. Multiple cooling zones share the same liquid inlet 21 and liquid outlet 22. That is, only one set of liquid supply pipeline is needed. In this way, the number of liquid supply pipelines is greatly reduced, the cost is reduced, and the layout is more convenient.

[0058] In addition, since each cooling zone has a first cooling channel 25 and a second cooling channel 26 with opposite flow directions, the cooling uniformity of the battery 3 can be improved, avoiding a large temperature difference between the two ends of the battery 3 along its length.

[0059] Preferably, such as Figure 2 to Figure 4 As shown, there are multiple first cooling channels 25 in each cooling zone, and the multiple first cooling channels 25 are distributed along the length direction of the liquid cooling plate 2, and the multiple first cooling channels 25 are arranged in parallel.

[0060] For example, such as Figure 2 to Figure 4 As shown, each cooling zone has three first cooling channels 25, which are distributed along the Y direction. The right end of each of the three first cooling channels 25 is connected to the liquid inlet channel 23.

[0061] It should be noted that the number of first cooling channels 25 is not limited to the above-mentioned three. For example, it can also be set to two, four or more. Those skilled in the art can flexibly set the specific number of first cooling channels 25 according to the specific circumstances in practical applications.

[0062] Preferably, such as Figure 2 to Figure 4 As shown, there are multiple second cooling channels 26 in each cooling zone, and the multiple second cooling channels 26 are distributed along the length direction of the liquid cooling plate 2, and the multiple second cooling channels 26 are arranged in parallel.

[0063] For example, such as Figure 2 to Figure 4 As shown, each cooling zone has four second cooling channels 26, which are distributed along the Y direction. The right ends of the four second cooling channels 26 are all connected to the return channel 24.

[0064] It should be noted that the number of second cooling channels 26 is not limited to the above-mentioned four. For example, it can also be set to two, three, five or more. Those skilled in the art can flexibly set the specific number of second cooling channels 26 according to the specific circumstances in practical applications.

[0065] Preferably, such as Figure 2 to Figure 4 As shown, multiple first cooling channels 25 and multiple second cooling channels 26 are alternately distributed along the length of the liquid cooling plate 2.

[0066] By alternating the distribution of multiple first cooling channels 25 and multiple second cooling channels 26 along the length of the liquid cooling plate 2, the cooling uniformity of the battery 3 can be further improved.

[0067] For example, each cooling zone has three first cooling channels 25 and four second cooling channels 26, which are arranged sequentially along the Y direction as second cooling channel 26, first cooling channel 25, second cooling channel 26, first cooling channel 25, second cooling channel 26, first cooling channel 25 and second cooling channel 26.

[0068] Preferably, such as Figure 2 to Figure 4 As shown, the liquid inlet 21 and the liquid outlet 22 on the liquid cooling plate 2 are located at the same end along the length of the liquid cooling plate 2.

[0069] For example, such as Figure 2 to Figure 4 As shown, both the liquid inlet 21 and the liquid outlet 22 are located at the lower right corner of the liquid cooling plate 2.

[0070] It should be noted that, in practical applications, those skilled in the art can place the liquid inlet 21 and the liquid outlet 22 on the same side of the liquid cooling plate 2, or they can place the liquid inlet 21 and the liquid outlet 22 on two opposite surfaces of the liquid cooling plate 2 respectively. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model, and should all be limited to the protection scope of this utility model.

Figure 4 (Viewed from above: the right side surface of liquid cooling plate 2).

[0072] By setting the liquid inlet 21 and the liquid outlet 22 on two opposite surfaces of the liquid cooling plate 2, it is easier to connect to the liquid supply pipeline.

[0073] Preferably, such as Figure 2 to Figure 4 As shown, the liquid inlet channel 23 and the liquid return channel 24 on the liquid cooling plate 2 are distributed along the thickness direction of the liquid cooling plate 2.

Figure 4 Viewed from above (left side of liquid cooling plate 2), the return flow channel 24 is close to the second surface of liquid cooling plate 2 (from...). Figure 4 (Viewed from above: the right side surface of liquid cooling plate 2).

[0074] For example, such as Figure 4 As shown, the liquid cooling plate 2 has a liquid inlet 21 on the left side surface and a liquid inlet channel 23 near the inside of the left side surface. The liquid cooling plate 2 has a liquid outlet 22 on the right side surface and a liquid return channel 24 near the inside of the right side surface.

[0076] In other words, the first surface of the liquid cooling plate 2 is not a flat surface, but an uneven surface with multiple protrusions 27 and recesses 28. A first cooling channel 25 is provided inside the position corresponding to the protrusion 27, and a second cooling channel 26 is provided inside the position corresponding to the recess 28. The battery 3 is preferably placed on the first surface of the liquid cooling plate 2. The bottom of the battery 3 is in contact with the protrusion 27, and there is a gap between the recess 28 and the bottom of the battery 3. This gap is conducive to the dissipation of heat from the battery 3.

[0077] It should be noted that, in practical applications, those skilled in the art can connect the other end of the first cooling channel 25 to the other end of the second cooling channel 26 by setting a channel in the liquid cooling plate 2, or by setting a connecting pipe on the liquid cooling plate 2 to connect the other end of the first cooling channel 25 to the other end of the second cooling channel 26. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should be limited to the protection scope of this utility model.
