[0031] In the existing technology, the liquid-cooled energy storage cabinets on the market still have some deficiencies in structure and design, such as unstable heat dissipation effect and the coolant in the liquid-cooled energy storage cabinet easily leaking into electrical components.

[0032] Based on this, the embodiment of the present invention provides a liquid-cooled energy storage cabinet. The cabinet is provided with a first cavity, a second cavity, a third cavity, and a fourth cavity. The first cavity is located above the second cavity, the third cavity is located to one side of the second cavity, and the fourth cavity is located above the third cavity. The first cavity is used to place the liquid cooling unit, the second cavity is used to place the liquid cooling control device, the third cavity is used to place the liquid cooling battery, and the fourth cavity is used to place the energy storage converter. Based on the structural design of multiple cavities, electrical components with different heat outputs are placed in different areas, thereby improving the heat dissipation stability of the liquid-cooled energy storage cabinet. At the same time, a liquid collection pan is provided at the bottom of the first cavity, which is used to collect leaked liquid from the liquid cooling control device. The second cavity is provided with a guide pipe, which runs through the first and second cavities. One end of the guide pipe is connected to the liquid collection pan, and the other end of the guide pipe is connected to the outside world. The guide pipe is used to guide the leaked liquid to the outside world. The cooperation between the liquid collection pan and the guide pipe can prevent the coolant in the liquid-cooled energy storage cabinet from leaking into the electrical components, thereby reducing the failure rate of the electrical components in the liquid-cooled energy storage cabinet.

[0033] Therefore, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0034] Reference Figure 1 、 Figure 2 and Figure 3 As shown, Figure 1 This is an overall structural diagram of the liquid-cooled energy storage cabinet provided by some embodiments of the present invention. Figure 2 This is a back structural diagram of a liquid-cooled energy storage cabinet provided by some embodiments of the present invention. Figure 3 This is a front structural diagram of a liquid-cooled energy storage cabinet provided by some embodiments of the present invention. The liquid-cooled energy storage cabinet includes a cabinet body 100, which includes a first cavity 110, a second cavity 120, a third cavity 130 and a fourth cavity 140. The first cavity 110 is located above the second cavity 120, the third cavity 130 is located on one side of the second cavity 120, and the fourth cavity 140 is located above the third cavity 130. The first cavity 110 is used to place the liquid cooling unit, the second cavity 120 is used to place the liquid cooling control equipment, the third cavity 130 is used to place the liquid-cooled battery, and the fourth cavity 140 is used to place the energy storage inverter. Based on the structural design of multiple cavities, electrical components with different heat generation are placed in partitions, thereby improving the heat dissipation stability of the liquid-cooled energy storage cabinet.

[0035] Among them, a liquid receiving pan 111 is provided at the bottom of the first cavity 110, and the liquid receiving pan 111 is used to collect leakage liquid of the liquid cooling control device. The second cavity 120 is provided with a guide pipe 121, which runs through the first cavity 110 and the second cavity 120. One end of the guide pipe 121 is connected to the liquid receiving pan 111, and the other end of the guide pipe 121 is connected to the outside world. The guide pipe 121 is used to guide the leakage liquid of the liquid receiving pan 111 to the outside world. Based on the cooperation between the liquid receiving pan 111 and the guide pipe 121, the coolant in the liquid-cooled energy storage cabinet can be prevented from leaking to the electrical components, thereby reducing the failure rate of the electrical components in the liquid-cooled energy storage cabinet.

[0036] And, from Figure 2 It can be seen that the fourth cavity 140 is provided with an air duct structure 141, which is used to guide the heat flow of the fourth cavity 140 to the outside, thereby improving the heat dissipation efficiency of the liquid-cooled energy storage cabinet.

[0037] Further, from Figure 3 It can be seen that a partition 150 is provided between the third cavity 130 and the fourth cavity 140. The partition 150 is used to isolate the heat exchange between the third cavity 130 and the fourth cavity 140, thereby preventing the energy storage converter with a large heat generation from affecting the heat dissipation of the liquid-cooled battery by generating heat, thereby improving the heat insulation efficiency inside the liquid-cooled energy storage cabinet and increasing the service life of the liquid-cooled battery inside the liquid-cooled energy storage cabinet.

[0038] Further, from Figure 2 It can be seen that multiple battery rails 131 are further provided on both sides of the third cavity 130. The battery rails 131 are arranged up and down between each other. The battery rails 131 are used to place the liquid-cooled batteries in the air and limit and fix the liquid-cooled batteries. Therefore, during the installation of the liquid-cooled batteries, the liquid-cooled batteries can be prevented from being excessively offset to the left and right, resulting in misalignment of the mounting holes, thereby improving the installation efficiency of the liquid-cooled batteries inside the liquid-cooled energy storage cabinet.

[0039] Further, from Figure 3 It can be seen that a leakage hole 132 is provided at the bottom of the third cavity 130. The leakage hole 132 is used to discharge the leaked liquid of the liquid-cooled battery to the outside. When the liquid of the liquid-cooled battery leaks, the leaked liquid can be discharged in time through the leakage hole 132 to prevent the leaked liquid from accumulating in the cabinet and affecting the service life of the liquid-cooled battery.

[0040] Further, from Figure 1 、 Figure 4 and Figure 5 It can be seen that Figure 4 This is a front view of a liquid-cooled energy storage cabinet provided by some embodiments of the present invention.

[0041] Further, from Figure 3 It can be seen that a dehumidifier 172 is fixed to the inner side of the second cabinet door 170, and the dehumidifier 172 is connected to the second cavity 120. The dehumidifier 172 is used to discharge the water vapor in the third cavity 130 to the outside, thereby preventing the water vapor in the third cavity 130 from affecting the internal circuit of the liquid-cooled battery, avoiding short circuit of the liquid-cooled battery, and improving the safety of the liquid-cooled energy storage cabinet.

[0042] Further, from Figure 3 It can be seen that a fire-fighting device 171 is also fixed to the inner side of the second cabinet door 170. The fire-fighting device 171 is arranged at the lower end of the dehumidifier 172. The fire-fighting device 171 includes a fire bottle (unmarked) and a heat-sensitive wire (unmarked). The heat-sensitive wire is used to detect the fire source in the cabinet 100 to trigger the fire bottle to extinguish the fire source in the cabinet 100. When the liquid-cooled battery catches fire, the heat-sensitive wire detects the fire source in the cabinet 100 and sends a signal to trigger the fire bottle to extinguish the fire source in the cabinet 100, thereby preventing the fire from spreading and improving the safety of the liquid-cooled energy storage cabinet.

[0043] Further, from Figure 2 It can be seen that a fan 181 is provided on the inner side of the third cabinet door 180, and the air outlet of the fan 181 is opposite to the interior of the fourth cavity 140. The fan 181 is used to guide the heat of the fourth cavity 140 to the air duct structure 141 in the form of airflow, thereby improving the heat dissipation efficiency of the liquid-cooled energy storage cabinet.
