[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] Example With the booming development of the new energy industry, energy storage equipment has been widely used in various industries. To ensure the stable operation of energy storage equipment under different operating conditions, it is usually necessary to use energy storage water-cooled plates for temperature control. However, the heat exchange area of ​​commonly used energy storage water-cooled plates is fixed, which can only match equipment with specific heat exchange requirements, thus limiting the application range of a single specification of water-cooled plate.

[0027] Therefore, this application discloses an energy storage water-cooled plate, which is used to abut against an energy storage module, as shown in the reference. Figure 1-2 The energy storage water-cooled plate disclosed in this utility model includes an inlet pipe 100 and an outlet pipe 200 arranged parallel to the inlet pipe 100. Multiple water plate units 300 are arranged between the inlet pipe 100 and the outlet pipe 200, and these units are arranged side-by-side along the length of the inlet pipe 100. By providing at least two water plate units 300, the heat exchange area of ​​the energy storage water-cooled plate is adjustable, thereby enabling the energy storage water-cooled plate to be applied to energy storage components with different heat exchange areas.

[0028] Of course, in order to make the energy storage water-cooled plate applicable to more energy storage modules of different sizes, refer to Figure 7-8 The number of water plate units 300 can also be set to 3, 4 or more, which are not shown in the attached figure.

[0029] In one embodiment of this utility model, the energy storage water-cooled plate can be used alone, or two, three or more sets of energy storage water-cooled plates can be used side by side, and the lengths of adjacent energy storage water-cooled plates can be different, thereby making the energy storage water-cooled plate applicable to a wider range.

[0030] Specifically, in one embodiment of this utility model, referring to Figure 3-4 The inlet pipe 100 has an outlet 110 on its wall, and the outlet pipe 200 has an inlet 210 on its wall. The water plate unit 300 includes a flat, rectangular first housing 310. Two side walls of the first housing 310, parallel to the extending direction of the inlet pipe 100, form a first heat exchange channel 311. The inlet end of the first heat exchange channel 311 is connected to the outlet 110 of the inlet pipe 100, and the outlet end is connected to the inlet 210 of the outlet pipe 200. (Refer to...) Figure 5 A plurality of fins 320 are provided in the inner cavity of the first housing 310, and the fins 320 are vertically fixed to the inner surfaces of two opposite side walls of the first housing 310.

[0031] Preferably, in one embodiment of this utility model, the fins 320 are arranged vertically, that is, the fins 320 are perpendicular to the extending direction of the water inlet pipe 100, so as to facilitate the installation and welding of the fins 320 and the first housing 310. Figure 5As shown, there are several fins 320, and the fins 320 cut the first heat exchange channel 311 into several parts. Water or other heat exchange fluids flowing through the first heat exchange channel 311 can exchange heat with the energy storage component better through the fins 320, thereby controlling the temperature of the energy storage component.

[0032] Furthermore, in one embodiment of the present invention, referring to Figure 6 The fins 320 extend in a wave shape along the fluid flow direction. The wave-shaped fins 320 have a larger contact area with the fluid, which makes the heat exchange between the energy storage water cooling plate and the heat exchange fluid more complete.

[0033] In one embodiment of this utility model, reference is made to Figure 3-4 The water plate unit 300 also includes a second housing 330 disposed between the first housing 310 and the water inlet pipe 100. The second housing 330 is also a flat rectangular shell. Two side walls of the second housing 330, parallel to the extension direction of the water inlet pipe 100, pass through to form a second heat exchange channel 331. The inlet end of the second heat exchange channel 331 is connected to the water inlet pipe 100, and the outlet end of the second heat exchange channel 331 is connected to the inlet end of the first heat exchange channel 311. No fins 320 are provided in the second heat exchange channel 331. When the heat exchange fluid enters the second heat exchange channel 331, this area serves as a buffer zone for the fluid. The heat exchange fluid is slowed down in the second heat exchange channel 331 and then flows through the first heat exchange channel 311 at a slower flow rate, so that the heat exchange between the fluid and the energy storage component at the first housing 310 can be more sufficient.

[0034] Specifically, refer to Figure 5-6 The cross-sectional opening size of the second housing 330 is the same as that of the first housing 310, so that welding the first housing 310 and the second housing 330 is more convenient.

[0035] In one embodiment of this utility model, combined with Figure 1 and Figure 4 The water plate unit 300 also includes an abutment plate 340, which is fixedly connected to the side wall of the first housing 310 for direct contact with the energy storage component. The abutment plate 340 and the extension direction of the water inlet pipe 100 are parallel. The abutment plate 340 compensates for the thickness difference between the outer wall of the first housing 310 and the water inlet pipe 100 or the water outlet pipe 200, so that the first housing 310 can fit more tightly with the energy storage component, ensuring smooth heat exchange between the energy storage water cooling plate and the energy storage component.

[0036] In one embodiment of this utility model, the inlet pipe 100 and the outlet pipe 200 are both spliced ​​together, that is, after determining the length of the energy storage component, the shorter inlet pipe 100 and the outlet pipe 200 are spliced ​​together.

[0037] In one embodiment of this utility model, reference is made to Figure 2 and Figure 3 The inlet pipe 100 is a closed loop pipe to facilitate the splicing of adjacent inlet pipes 100.

[0038] In one embodiment of this utility model, reference is made to Figure 2 and Figure 3 The outlet pipe 200 is a closed loop pipe to facilitate the splicing of adjacent outlet pipes 200.

[0039] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 A first connector 410 and a second connector 420 are provided at both ends of the inlet pipe 100 and the outlet pipe 200, respectively. The first connector 410 is an external hexagonal joint, and the second connector 420 is a plug. Alternatively, the first connector 410 is a plug, and the second connector 420 is an external hexagonal joint. The external hexagonal joint at the inlet pipe 100 is used to connect to the circulation pump to facilitate the flow of fluid.

[0040] In one embodiment of this utility model, the position of the external hexagonal connector at the water inlet pipe 100 can be interchanged with that of the plug, so that the pipeline connecting the water inlet pipe 100 and the circulation pump is simplified.

[0041] In one embodiment of this utility model, the position of the external hexagonal connector at the outlet pipe 200 can be interchanged with that of the plug, so as to simplify the pipeline connecting the outlet pipe 200 and the circulation pump.

[0042] In one embodiment of this utility model, reference is made to Figure 3-4 The water plate unit 300 also includes a mounting plate 350, which is fixed to the side wall of the first housing 310 perpendicular to the extending direction of the water inlet pipe 100. The mounting plate 350 is provided with mounting holes. By providing the mounting plate 350, the energy storage water-cooled plate can be firmly combined with the energy storage component.

[0043] Preferably, in one embodiment of the present invention, mounting plates 350 are provided on both sides of the first housing 310, thereby making the first housing 310 and the energy storage component more firmly connected.

[0044] In one embodiment of this utility model, both the first housing 310 and the second housing 330 are aluminum alloy housings, which ensures heat transfer efficiency while controlling the production cost of the energy storage water cooling plate.

[0045] Of course, in one embodiment of this utility model, the first housing 310 and the second housing 330 can also be copper housings, so as to make the heat exchange efficiency of the energy storage water cooling plate and the energy storage component higher.

[0046] This utility model also discloses a temperature management device, which includes a heat exchange unit, a fluid circulation unit, a heat exchange unit, and a temperature control unit. The heat exchange unit is used for heat exchange with the energy storage component; the fluid circulation unit drives the fluid at the heat exchange unit to circulate within the pipes; the heat exchange unit enables heat exchange between the coolant in the energy storage water-cooled plate and the external environmental medium; and the temperature control unit dynamically adjusts the flow rate of the fluid circulation unit based on the received temperature signal, thereby ensuring that the temperature at the energy storage unit remains within a suitable temperature range.

[0047] Specifically, in one embodiment of this invention, the heat exchange unit includes the aforementioned energy storage water-cooled plate, which is thermally bonded to the energy storage component. The fluid circulation unit includes a circulation pump and a pipeline connecting the inlet pipe 100 and the outlet pipe 200. Through the operation of the circulation pump, the coolant in the energy storage water-cooled plate circulates to remove heat from the energy storage component. The heat exchange unit is connected in series in the pipeline of the circulation pump and is used for heat exchange between the coolant in the energy storage water-cooled plate and the external environmental medium. The temperature control unit includes a temperature sensor mounted on the energy storage water-cooled plate, a control module for receiving temperature sensor signals, and an electric heater electrically connected to the control module.

[0048] Specifically, when the temperature management equipment is working, the circulation pump starts, driving the coolant to flow through the energy storage water-cooled plate and pipelines. As the coolant passes through the energy storage components, it carries away the heat from the components, and as it passes through the heat exchange unit, the heat carried by the coolant is exchanged, resulting in cooling. When the temperature sensor detects a high temperature, the control module increases the power of the circulation pump based on the feedback signal from the temperature sensor, increasing the pump's flow rate per unit time. This increases the flow rate of coolant through the energy storage water-cooled plate, thereby lowering the temperature of the energy storage components.

[0049] Of course, when the energy storage module is at a low temperature (below zero), the control module receives an excessively low temperature signal from the temperature sensor. The control module then activates the electric heater, which heats the coolant. The fluid introduced by the circulation pump to the energy storage water-cooling plate becomes hot fluid, and the water-cooling plate heats the energy storage module, raising its temperature to a suitable operating temperature. Different temperature signals from the temperature sensor are fed back to the control module, which then controls the circulation pump to increase the flow rate per unit time or controls the heater to heat the coolant. This heat, in turn, heats or cools the energy storage module through the water-cooling plate, maintaining its temperature within a set threshold range.

[0050] This utility model also discloses an energy storage system, which includes the above-mentioned energy storage water-cooled plate and / or temperature management device, and the energy storage system has all the advantages of the energy storage water-cooled plate and / or temperature management device.

[0051] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
