Therefore, a coolant circulation device for energy storage cabinets is proposed to solve the above problems. Utility Model Content

[0011] The installation and adjustment assembly includes a first mounting bracket and a second mounting bracket fixedly installed on the inner wall of the energy storage cabinet.

[0014] As a further description of the above technical solution:

[0015] The slow-flow heat exchange assembly includes a first loop-shaped slow-flow tube and a second loop-shaped slow-flow tube. An inlet pipe is fixedly connected between the center of the back of the first loop-shaped slow-flow tube and the liquid supply pipe. An outlet pipe is fixedly connected between the center of the back of the second loop-shaped slow-flow tube and the connecting pipe.

On the outer surface, the filter 61 has a filter screen 62 that is movably snapped into the inside for intercepting impurities in the coolant. The top of the filter 61 is threadedly connected to a threaded and removable sealing cap 63. The upper surface of the sealing cap 63 is fixedly connected to a connecting pipe 7. Through the filter assembly 6, the filter 61 with the built-in filter screen 62 can filter and remove impurities from the coolant circulating between the main body 1 and the slow-flow heat exchange assembly 9 under the drive of the liquid supply pump 3. The filter screen 62 can be disassembled and cleaned through the threaded and removable sealing cap 63, thereby preventing impurities from accumulating and clogging the circulating coolant.

[0034] Reference Figure 1 , Figure 3 and Figure 4A slow-flow heat exchange assembly 9 is provided between the pipe 7 and the liquid supply pipe 4. Installation and adjustment assemblies 8 are provided on both sides of the slow-flow heat exchange assembly 9. The installation and adjustment assemblies 8 include a first mounting bracket 81 and a second mounting bracket 82 fixedly installed on the inner wall of the energy storage cabinet. A guide rod 83 is fixedly connected to the inner surface of the first mounting bracket 81. A guide seat 85 is sleeved on the outer periphery of the guide rod 83. There are two guide seats 85, which are mirror images of each other along the central axis of the guide rod 83. A bidirectional threaded rod 84 is movably connected to the inner surface of the second mounting bracket 82. An adjustment seat 86 is threadedly connected to the outer periphery of the bidirectional threaded rod 84. There are two adjustment seats 86, which are mirror images of each other along the central axis of the bidirectional threaded rod 84. The slow-flow heat exchange assembly 9 includes a first loop-shaped slow-flow tube 91 and a second loop-shaped slow-flow tube 92. One end of both the first loop-shaped slow-flow tube 91 and the second loop-shaped slow-flow tube 92 is fixedly connected to the inner surface of the guide seat 85. The other ends of the first loop-shaped slow-flow tube 91 and the second loop-shaped slow-flow tube 92 are fixedly connected to the inner surface of the adjusting seat 86. The center of the back of the first loop-shaped slow-flow tube 91 is fixedly connected to the liquid supply tube 4, and the center of the back of the second loop-shaped slow-flow tube 92 is fixedly connected to the connecting pipe 7. The first loop-shaped slow-flow tube 91 and the second loop-shaped slow-flow tube 92 are connected through a telescopic tube 93. By installing the adjusting component 8 and the slow-flow heat exchange component 9, and by rotating the bidirectional threaded rod 84, the first loop-shaped slow-flow tube 91 and the second loop-shaped slow-flow tube 92 assembled between the two guide seats 85 and the adjusting seat 86 can be adjusted relative to each other along the length of the guide rod 83. The first loop-shaped slow-flow tube 91 and the second loop-shaped slow-flow tube 92, combined with the built-in spiral guide vane 96, perform a slow-flow circulation of coolant guided by both sides, thereby achieving a cooling effect by absorbing heat over a large area in the high-temperature position of the energy storage cabinet.

[0035] Reference Figure 1 , Figure 4 and Figure 5 Both the first loop-shaped slow-flow tube 91 and the second loop-shaped slow-flow tube 92 have spiral guide vanes 96 fixedly connected inside. The inner walls of both the first loop-shaped slow-flow tube 91 and the second loop-shaped slow-flow tube 92 are provided with cavities 97. The outer surfaces of both the first loop-shaped slow-flow tube 91 and the second loop-shaped slow-flow tube 92 are fixedly connected with heat exchange fins 98.

The heat exchange fins 98 inside the cavity 97 are connected through the channel 99 on the outer surfaces of the first loop-shaped slow-flow tube 91 and the second loop-shaped slow-flow tube 92, which facilitates efficient heat exchange and cooling in the energy storage cabinet.

[0036] Working principle: In use, the first mounting bracket 81 and the second mounting bracket 82 are fixed to the inner wall of the energy storage cabinet by mounting bolts. Driven by the liquid supply pump 3, the coolant circulates between the main body 1 and the slow-flow heat exchange component 9. The filter 61 of the built-in filter screen 62 can effectively filter and intercept impurities. The filter screen 62 can be easily disassembled and cleaned by the threaded sealing cap 63 to prevent impurities from accumulating and clogging during the coolant circulation. By manually rotating the bidirectional threaded rod 84, the first loop-shaped slow-flow pipe 91 and the second loop-shaped slow-flow pipe 92 between the guide seat 85 and the adjusting seat 86 can be adjusted relative to each other along the length of the guide rod 83. Combined with the built-in spiral guide vane 96, these two sections of slow-flow pipe achieve double-sided guided slow-flow circulation of coolant, thereby effectively absorbing the heat in the high-temperature area inside the energy storage cabinet and achieving a cooling effect.
