Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation devices, and in particular to a heat dissipation device for an energy storage battery pack. Background Art

[0002] With the rise of renewable energy, energy storage technology has become a hot topic in the energy field. As the core component for storing electrical energy, energy storage battery packs play a key role in the stable supply of renewable energy. With the improvement of environmental awareness, it has become a common practice to use recycled batteries for energy storage battery packs. Although they have lost some performance in the original equipment, they still have the potential for reuse after proper treatment and repair. Using recycled batteries for energy storage battery packs can not only effectively extend their service life, but also is conducive to the sustainable use of resources and has positive significance for environmental protection. However, during the energy storage process, battery cells will generate a lot of heat. High temperature will significantly reduce the performance and life of the battery, and may even cause safety hazards. Therefore, an efficient heat dissipation system is particularly important.

[0003] In the prior art, there are two common heat dissipation methods for energy storage battery packs, namely air cooling and liquid cooling. The air cooling method has the characteristics of simple system, low manufacturing cost, and easy installation, but it is only suitable for scenes with low energy density of energy storage battery packs. The liquid cooling method has the characteristics of large heat load, low flow resistance, and high heat exchange efficiency. Therefore, liquid cooling is widely used in scenes with high energy density of energy storage battery packs, fast charging and discharging speeds, and large changes in ambient temperature. The existing liquid cooling technology heat dissipation structure is usually fixedly arranged for pre-designed highly integrated energy storage battery packs. The advantage of such a design is that the entire energy storage device occupies less space and is easy to install, but the disadvantage is that it can only adapt to energy storage battery packs of preset shapes, and cannot adapt to recycled battery cells of different sizes, thereby reducing the battery application range of the energy storage battery pack heat dissipation device.

During the entire heat dissipation process, the heat dissipation controller can adjust the operating power of the coolant circulation pump in real time according to the data measured by the internal detection mechanism. When the internal detection mechanism measures that the temperature of the battery body is higher than the preset value, the heat dissipation controller will automatically increase the operating power of the coolant circulation pump of the corresponding interlayer, increase the cooling effect by increasing the flow rate of the coolant in this layer, and automatically reduce the operating power of the coolant circulation pump after the temperature drops, thereby achieving the purpose of reducing the operating cost of the device while dissipating the heat of the battery body.

The inner surfaces of the mounting grooves 502 are slidably connected with connecting rods 503.

[0026] Specifically, by means of the installation grooves 502 provided on the left and right sides of the installation box 1, the connecting rod 503 can be installed at a height parallel to the rear block 501. When installing the battery body 3, the connecting rod 503 is first removed, and the battery body 3 and the cooling fin mechanism 6 are arranged in an interlaced manner. Subsequently, the connecting rod 503 is installed inside the installation grooves 502, and the positions of the cooling fin mechanism 6 are fixed to each other through the cooperation between the rear block 501 and the installation grooves 502.

The lower front part of the liquid cooling fin 601 is fixedly connected with an inlet connector 604, and the inlet connector 604 is fixedly connected to the cooling tube 602. The input end is fixedly connected, and a plurality of connecting blocks 605 are fixedly connected to the middle of the front side of the liquid-cooled heat sink 601. A fixing plate 606 is arranged on the front side of the connecting block 605. The connecting block 605 and the fixing plate 606 are fixed to each other by fixing screws 607. The adjacent sides of the connecting block 605 are slidably connected to the outer surface of the connecting rod 503. A fixing slot 608 is fixedly connected to the rear side of the liquid-cooled heat sink 601, and the inner surface of the fixing slot 608 is slidably connected to the outer surface of the rear block 501.

[0028] Specifically, when installing the liquid cooling heat sink 601, firstly, the liquid cooling heat sink 601 and the battery body 3 are arranged in a staggered form, and the adjacent sides of the liquid cooling heat sink 601 are closely attached to the outer walls of the battery body 3 on both sides to achieve the best heat dissipation effect, and the fixing groove 608 on the rear side of the liquid cooling heat sink 601 is clamped on the outer surface of the rear clamping block 501, and then the connecting rod 503 is installed along the installation groove 502, and after the connecting rod 503 is pushed between the connecting blocks 605, it is fixed with the fixing plate 606 and the fixing screw 607, thereby completing the liquid cooling. The heat sink 601 is fixed. When the position of the liquid-cooled heat sink 601 needs to be adjusted, the fixing plate 606 and the fixing screws 607 can be removed to adjust the position of the liquid-cooled heat sink 601, so that the liquid-cooled heat sink 601 can be in close contact with the battery body 3 of different sizes and dissipate heat to the battery body 3.

[0029] Please see attached Figure 5The coolant circulation mechanism 7 includes a hot flow tube 701 and a cold flow tube 702.

[0030] Specifically, when the coolant inside the cooling tube 602 is circulated, the coolant that has been fully cooled by the heat dissipation mechanism 9 is input into the coolant circulation pump 705 along the cold circulation mechanism 10, and is sent into the cooling tube 602 by the coolant circulation pump 705 along the cold flow liquid separator valve 704 and the cold flow tube 702 to cool the liquid cooling fin 601, thereby dissipating heat from the battery body 3.

During the entire heat dissipation process, the heat dissipation controller 2 can adjust the operating power of the coolant circulation pump 705 in real time according to the data measured by the internal detection mechanism 11. When the internal detection mechanism 11 measures that the temperature of the battery body 3 is higher than the preset value, the heat dissipation controller 2 will automatically increase the operating power of the corresponding interlayer coolant circulation pump 705, increase the cooling effect by increasing the flow rate of the coolant in this layer, and automatically reduce the operating power of the coolant circulation pump 705 after the temperature drops, thereby achieving the purpose of reducing the operating cost of the device while dissipating the heat of the battery body 3.
