Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet technology, and in particular to an energy storage cabinet air duct structure. Background Technology

[0002] Due to outdoor environmental factors, the battery temperature inside the battery box can easily rise during charging and discharging of outdoor energy storage systems. If the temperature exceeds the specified value of the battery, the performance and lifespan of the battery inside the battery box will be greatly affected. In order to ensure the overall performance of the battery and meet the charging and discharging requirements of some outdoor fields, the reasonable heat dissipation design of the energy storage system is a key factor to consider. The existing heat dissipation methods still have certain defects and need to be improved.

[0003] Currently, the design of heat dissipation for outdoor energy storage systems mainly falls into two categories. The first is the battery box level heat dissipation design, which mainly uses a fan installed in each battery box for air cooling and ventilation holes in the cabinet. This method has a significant heat dissipation effect inside the battery box, but the heat inside the cabinet cannot be dissipated in time, resulting in poor heat dissipation within the cabinet and poor overall heat dissipation effect. The second is the cabinet level heat dissipation design, which mainly uses a fan added to the entire cabinet to directly utilize the cabinet structure to form air ducts for heat dissipation. The biggest problem with this design is that the air ducts inside the cabinet are scattered and cannot form a centralized heat dissipation channel, thus failing to achieve the ideal heat dissipation effect.

The air outlet pipe 5 is connected to the air outlet 16. An exhaust fan 17 is fixedly connected inside the air outlet 16.

[0024] An installation groove 34 is provided on the outer side of the air outlet duct 5. A dustproof net 7 is provided in the installation groove 34. A countersunk hole 31 is horizontally passed through each side of the inner wall of the installation groove 34. A support rod 29 is movably inserted in the countersunk hole 31. One end of the support rod 29 is fixedly connected to a pull block 28, which abuts against the outer side of the air outlet 16. The other end is fixedly connected to an insert block 32. A spring 30 is sleeved on the outer edge of the support rod 29. A slot 33 is provided on the side of the dustproof net 7. The insert block 32 is inserted into the slot 33.

[0025] Two second guide grooves 12 are vertically provided on the left and right sides of the frame 1, and a second guide block 13 is slidably connected in each second guide groove 12. Two second guide blocks 13 are symmetrically fixed on the inner side of each side plate 4. Two first guide grooves 11 are symmetrically provided on the front and rear sides of the frame 1, and a first guide block 10 is slidably connected in each first guide groove 11. Two first guide blocks 10 are symmetrically fixed on the inner side of the rectangular frame 8 and the inner side of the back plate 2.

[0026] A third guide groove 14 is symmetrically provided on the inner edge of the rectangular frame 8 and the inner edge of the back plate 2. A third guide block 15 is slidably connected in each third guide groove 14. A third guide block 15 is fixed on both sides of each side plate 4. Two first threaded grooves 24 are symmetrically provided on both sides of the frame 1. The internal thread of the first threaded groove 24 is connected to the external threaded block 25. A second threaded groove 26 adapted to the external threaded block 25 is provided on the inner side of the side plate 4. A connecting rod 27 is movably passed through the second threaded groove 26. One end of the connecting rod 27 is fixedly connected to the external threaded block 25, and the other end is fixedly connected to the rotating block 3.

[0027] By fixing a heat-conducting plate 19 within the frame 1, setting a corrugated groove 21 within the heat-conducting plate 19, and setting a vent 20 on the top surface of the heat-conducting plate 19 communicating with the corrugated groove 21, and setting exhaust and intake components communicating with the corrugated groove 21 on the door panel 6 and back panel 2 respectively, a single air duct is formed inside the energy storage cabinet, making the heat dissipation air duct inside the energy storage cabinet more concentrated and improving the heat dissipation effect of the energy storage cabinet. The corrugated groove 21 within the heat-conducting plate 19 slows down the air exhaust speed inside the energy storage cabinet, allowing external air to carry away more heat when passing through the corrugated groove 21, thereby optimizing the heat dissipation effect of the energy storage cabinet. The dustproof mesh 7 is also installed. The dust in the air entering the energy storage cabinet acts as a filter, preventing dust from entering the cabinet. Dust covering the surface of the components inside the cabinet affects the heat dissipation of the components. The dustproof net 7 is connected to the energy storage cabinet using spring 30, slot 33, and plug 32, making it easy to disassemble the dustproof net 7 and clean the dust accumulated on it. The side plate 4, back plate 2, and door plate 6 are installed on the outside of the frame 1 through multiple guide grooves and guide blocks, and are fixed to the frame 1 by external threaded blocks 25, which facilitates the disassembly of the external structure of the energy storage cabinet and makes it convenient to maintain the components inside the energy storage cabinet.

[0028] Working principle: The component is placed on the heat-conducting plate 19. The temperature of the component during operation is transferred to the heat-conducting plate 19. The intake fan 22 draws outside air through the dust filter 7 and sends it into the corrugated groove 21 in the heat-conducting plate 19. At the same time, the exhaust fan 17 exhausts the heat from the corrugated groove 21. When the air in the corrugated groove 21 is exhausted outward, it forms a suction force flowing inward through the vents, drawing the heat from the heat-conducting plate 19 and the component on the heat-conducting plate 19 into the corrugated groove 21. Under the guiding effect of the multiple bends in the corrugated groove 21, the exhaust speed of the heat in the corrugated groove 21 is slowed down, so that the air volume in the corrugated groove 21 can carry a large amount of heat at one time. This improves the heat dissipation of the energy storage cabinet. When too much dust accumulates on the dust filter 7, pull the pull block 28. The pull block 28 drives the insert block 32 to retract from the slot 33 into the large diameter end of the countersunk hole 31. At the same time, the spring 30 is compressed. Then, the dust filter 7 can be removed from the mounting slot 34 for cleaning. When it is necessary to maintain the internal components of the energy storage cabinet, rotate the rotating block 3. The rotating block 3 drives the external thread block 25 to rotate through the support rod 29, so that the external thread block 25 is screwed from the first thread groove 24 into the second thread groove 26. Then, pull the two side plates 4 upward to separate the two side plates 4 from the frame 1. Then, the back plate 2 and the rectangular frame 8 can be removed respectively.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
