[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0047] Please see Figure 1 This application provides an energy storage temperature control mechanism 1, comprising:

[0048] The cabinet 2 includes a bottom plate 21 and four side plates 22, the four side plates 22 surrounding the bottom plate 21 to form a cabinet space 23;

[0049] A liquid cooling plate 4 is disposed inside the cabinet 2. The liquid cooling plate 4 is disposed adjacent to the bottom plate 21. A cooling pipe 40 is provided on the side of the liquid cooling plate 4 away from the bottom plate 21.

[0050] A heating plate 5 is disposed inside the cabinet 2, and the heating plate 5 is arranged adjacent to the cooling pipe 40 of the liquid cooling plate 4;

[0051] The lid 6 covers the four side plates 22 on the side opposite to the bottom plate 21 to enclose the box space 23. The lid 6 is provided corresponding to the heating plate 5, and an electrical installation space (not shown in the figure) is formed between the lid 6 and the heating plate 5.

[0052] This embodiment of the application sets up a liquid cooling plate 4 and a heating plate 5 inside the cabinet 2. The liquid cooling plate 4 is adjacent to the bottom plate 21 of the cabinet 2 to facilitate heat exchange. Moreover, the heating plate 5 is adjacent to the cooling pipe 40 of the liquid cooling plate 4. This allows for both cooling through the liquid cooling plate 4 and heating through the heating plate 5, achieving controllable temperature rise and fall, reducing the time required for temperature adjustment, and enabling rapid adjustment of the internal temperature of the energy storage device to meet the optimal operating temperature range of the battery module through the liquid cooling plate 4 and the heating plate 5. This effectively protects the safety and lifespan of the battery and other electronic components.

[0053] Understandably, the electrical installation space is used to house components such as the battery module 3. The cover 24 closes onto the top of the four side panels 22 to enclose the enclosure space 23, effectively protecting the internal battery module 3 from external environmental influences such as dust, moisture, contaminants, and physical damage.

[0054] Please see Figure 1 , Figure 2 The base plate 21 is provided with a heat dissipation port 20, and the liquid cooling plate 4 is provided with a heat dissipation structure 41 on the surface facing the base plate 21, and the heat dissipation structure 41 is provided corresponding to the heat dissipation port 20.

[0055] The base plate 21 has heat dissipation vents 20 for exposing the liquid cooling plate 4. The design of the heat dissipation vents 20 allows the liquid cooling plate 4 to be directly exposed to the air, increasing the contact area with the external environment and thus improving heat dissipation efficiency. This allows the heat generated by the battery module 3 to be more effectively conducted away through the liquid cooling plate 4, helping to reduce the temperature inside the cabinet 2.

[0056] Please see Figure 1 , Figure 2 The heat dissipation vent 20 is rectangular, and the heat dissipation structure 41 includes heat dissipation fins and / or heat dissipation columns.

[0057] The liquid cooling plate 4 is positioned adjacent to the base plate 21 to facilitate heat exchange with the external environment. Furthermore, the liquid cooling plate 4, equipped with a heat dissipation structure 41, further facilitates efficient heat exchange with the external environment through the heat dissipation vents 20 on the base plate 21, carrying away the heat generated by the battery module 3 via heat conduction. The heat dissipation structure 41 is housed within the heat dissipation vents 20, resulting in a compact cabinet structure and improved space utilization. The heat dissipation structure 41 increases the contact area with the external environment, further enhancing heat dissipation efficiency. In addition, a sealing structure (not shown in the figure) can be configured around the edges of the heat dissipation vents 20 to ensure good sealing performance of the cabinet 2 while dissipating heat, preventing liquid leakage and ensuring the safety and reliability of the cabinet 2.

[0058] Please see Figure 2 There are multiple heat dissipation vents 20, which are evenly distributed on the base plate 21. This ensures that the heat from the liquid cooling plate 4 can be dissipated more evenly to the external environment, which helps to avoid local overheating and improve the overall heat dissipation efficiency.

[0059] In one embodiment, the heat dissipation structure 41 can be a ribbed heat dissipation fin or a columnar heat dissipation column. The heat dissipation fin protrudes from the lower surface of the liquid cooling plate 4 to increase the heat dissipation area and improve heat dissipation efficiency. In another embodiment, the heat dissipation structure 41 can include both ribbed heat dissipation fins and columnar heat dissipation columns, which are spaced apart and protruding from the lower surface of the liquid cooling plate 4. The heat dissipation fins provide a large surface area for rapid heat dissipation, while the heat dissipation columns can effectively conduct heat from the liquid cooling plate 4 to the heat dissipation fins and the surrounding air. Furthermore, to further improve heat dissipation efficiency, at least one of the four side plates 22 can be provided with a cooling fan or heat dissipation holes (not shown in the figure).

[0060] Please see Figure 1 The liquid cooling plate 4 is provided with a first liquid inlet 42 and a first liquid outlet 43. The two ends of the cooling pipe 40 are respectively connected to the first liquid inlet 42 and the first liquid outlet 43. The side plate 22 is provided with a second liquid inlet 221 and a second liquid outlet 222. The first liquid inlet 42 and the second liquid inlet 221 are connected, and the first liquid outlet 43 and the second liquid outlet 222 are connected, which facilitates connection with an external cooling system to realize liquid cooling circulation.

[0061] Please see Figure 4 The liquid cooling plate 4 has a flow channel on the side opposite to the bottom plate 21. The flow channel is arranged in an S-shape and meanders. The two ends of the flow channel are respectively connected to the first liquid inlet 42 and the first liquid outlet 43. The heating plate 5 seals the flow channel to form the cooling pipe 40.

[0062] Please see Figure 4 , Figure 5The liquid cooling plate 4 has a groove 44 on the side opposite to the bottom plate 21, and the heating plate 5 is disposed in the groove 44. The groove 44 and the heating plate 5 have the same shape.

[0063] Understandably, the heating plate 5, by sealing the flow channel to form the cooling pipe 40, enables the heating plate 5 to rapidly heat the liquid within the cooling pipe 40. The heating plate 5's fitting within the groove 44 enhances the sealing effect of the flow channel, preventing leakage. Optionally, a sealing gasket is further provided at the connection point between the groove 44 and the heating plate 5 to further improve the sealing effect and prevent leakage.

[0064] Please see Figure 4 , Figure 5 , Figure 6 The energy storage temperature control mechanism 1 also includes:

[0065] Temperature sensor 7 is disposed on the liquid cooling plate 4;

[0066] A water pump (not shown in the figure) is provided with a water supply port and a water return port, wherein the water supply port and the water return port are respectively connected to the first liquid inlet 42 and the first liquid outlet 43;

[0067] Temperature control device 8 is installed outside the cabinet 2 and electrically connected to the heating plate 5, the temperature sensor 7 and the water pump. The temperature control device 8 is used to adjust the opening and closing of the heating plate 5 and the water pump according to the temperature data detected by the temperature sensor 7.

[0068] This application also provides an energy storage cabinet, comprising:

[0069] The energy storage and temperature control mechanism 1 mentioned above;

[0070] The battery module 3 is disposed within the electrical appliance installation space, and the battery module 3 abuts against the heating plate 5.

[0071] Furthermore, the energy storage cabinet also includes:

[0072] An inverter (not shown in the figure) is installed in the electrical installation space and is electrically connected to the battery module 3.

[0073] Please see Figure 7 and Figure 8 The energy storage temperature control mechanism 1 also includes a fixed frame 9, which includes a carrying plate 91 and multiple limiting structures 92. The multiple limiting structures 92 are respectively disposed on the sides of the carrying plate 91 to enclose the installation space 90, thereby enhancing the stability and strength of the entire frame. This helps to ensure that the installed energy storage temperature control mechanism 1 remains stable during operation.

[0074] The limiting structure 92 can be a baffle 921 or multiple support columns 922. Multiple baffles 921 or support columns 922 are arranged around the loading plate 91 and enclose the installation space 90. Figure 7 and Figure 8 As illustrated, the limiting structure 92 includes a baffle 921 and multiple support columns 922. The carrying plate 91 has two opposite short sides and two opposite long sides. The baffle 921 is disposed on one of the two short sides of the carrying plate 91, and the multiple support columns 922 are respectively disposed on the two long sides. The multiple support columns 922 and the baffle 921 cooperate to form a hollow installation space 90. During installation, the side without the baffle 921 and support columns 922 is used as the installation port. The energy storage and temperature control mechanism 1 is placed into this installation port. The inlet pipe 5 and the outlet pipe 6 are both arranged in the installation port, which facilitates installation.

[0075] Please see Figure 7 , Figure 8 and Figure 9 Multiple energy storage temperature control mechanisms 1 are stacked within the installation space 90, with the liquid cooling plate 4 in each mechanism 1 located on the side facing the carrier plate 91 to achieve effective cooling. Thermally conductive gap fillers can be provided between the energy storage temperature control mechanisms 1 to improve heat transfer efficiency. A guide channel can also be provided on the first side 211 of the base plate 21 to guide the heat dissipated by the heat dissipation structure 41 to be discharged through the heat dissipation port 20.

[0076] In the energy storage temperature control mechanism and energy storage cabinet of this application embodiment, a liquid cooling plate 4 and a heating plate 5 are arranged inside the cabinet 2. The liquid cooling plate 4 is arranged adjacent to the bottom plate 21 of the cabinet 2 to facilitate heat exchange. Moreover, the heating plate 5 is arranged adjacent to the cooling pipe 40 of the liquid cooling plate 4. This allows for both cooling through the liquid cooling plate 4 and heating through the heating plate 5, achieving controllable temperature rise and fall, reducing the time required for temperature adjustment, and enabling rapid adjustment of the internal temperature of the energy storage device to meet the optimal operating temperature range of the battery module through the liquid cooling plate 4 and the heating plate 5, effectively protecting the safety and lifespan of the battery and other electronic components.
