Description

Technical Field

[0001] The invention belongs to the technical field of batteries, and in particular relates to an anti-expansion new energy battery. Background Art

[0002] New energy batteries are devices that can convert renewable energy (such as solar energy, wind energy, etc.) or non-fossil energy (such as nuclear energy) into electrical energy and store it. They provide clean and sustainable energy solutions and can be used to supply power, store energy and drive various devices and systems, including electric vehicles, renewable energy power stations, and household and industrial electricity. Due to their high efficiency, environmental protection and renewable characteristics, new energy batteries play an important role in energy transformation and climate change mitigation. Currently, common types of new energy batteries include lithium-ion batteries, sodium-ion batteries, solid-state batteries, etc.

[0003] Some types of new energy batteries (such as lithium-ion batteries) are prone to expansion under high temperature conditions, affecting their performance and life. The expansion may cause damage to the internal structure of the battery, and even cause battery short circuit and safety problems. Existing new energy batteries are usually cooled by natural cooling, air cooling system or water cooling system. The water cooling plate is a thin sheet of heat dissipation material. The coolant (usually water) is guided to the back of the battery module or battery chip through the micro channels on its surface. The water cooling plate can effectively absorb and conduct the heat generated by the battery to improve the overall heat dissipation capacity. However, this method is usually set at the bottom of the battery, and the upper part dissipates heat slowly, which is easy to cause uneven heat dissipation. In addition, general new energy batteries are usually configured using one of the above three cooling methods. A single cooling method is difficult to meet the multi-environment use requirements of new energy batteries. Therefore, we hope to design a new energy battery with a new structure to solve this problem. Summary of the invention

At the same time, the air supply component 400 passes the external low-temperature air through the air supply box 410 and the exhaust pipe 5142. The two air supply duct rows 420 are transported to the front and rear sides of the right end between the bottom shell 110 and the upper shell 120, so that the external air quickly enters the bottom shell 110 and promotes the rapid flow of the air inside the bottom shell 110. Under the negative pressure of the air cooling plate 1 511 of the air cooling unit 1 510 and the air cooling plate 2 521 of the air cooling unit 2 520, part of the low-temperature air quickly passes through the air inlet filter frame 1 513 and the air inlet filter frame 2 523 located at the right end of the air cooling plate 1 511 and the air cooling unit 2 520. Since a plurality of equally spaced partition plates 5112 are arranged in the air cavity 5111 inside the air cooling plate 1 511, the air cavity 5111 is divided into a plurality of partition plates 5112. The cross section of the strip-shaped cavity is reduced, which increases the wind speed. The air cooling plate 511 is in contact with the battery core 600 through the heat conductive silicone gasket 512. The heat conductive silicone gasket 512 conducts the heat on the upper side of the battery core 600 to the air cooling plate 511. The multiple heat dissipation fins 5113 in the air cavity 5111 expand the contact surface of the air, so that the fast-flowing air in the air cavity 5111 can exchange heat more quickly and take away the heat. The fast-flowing air enters the air duct 5142 of the exhaust member 514 through the multiple taps 5143 at the left end of the air cooling plate 511, and passes through the corrugated pipe 5143 connected to the exhaust pipe 220. 141 is exported to the exhaust box 210, and then discharged from the battery box 100 by the fan module. The operation of the air-cooling plate 2 521 is the same as that of the air-cooling plate 1 511, and they operate synchronously. The cold air entering the air-cooling plate 2 521 reaches the exhaust component 2 524 after heat exchange, and finally reaches the exhaust fan module 230 through the exhaust pipe 240 and the exhaust box 210, and is discharged together with the air in the air-cooling plate 1 511 (the above-mentioned exhaust fan module 230 and the supply fan module can both adopt the fan modules currently available on the market, and the specific model and specifications can be flexibly selected according to the size of the battery box 100, and are not limited to a specific model).

[0065] The exhaust assembly 200 can extract the heat generated by the battery cells 600 inside the battery box 100 by accelerating the air flow through the air cooling assembly 500, which can not only speed up the air flow rate in the battery box 100, but also quickly guide the hot air in the battery box 100 to achieve the purpose of rapid cooling;

The anti-expansion new energy battery according to claim 7, characterized in that: A plurality of mounting frames (340) are mounted between the left and right ends of the cooling tube group (350) and the left and right ends of the cooling tube group (360). The mounting frames (340) include mounting feet (341), an outer wall frame (342), an inner wall frame (343) and a partition (344). The specifications of the outer wall frame (342) are the same as those of the inner wall frame (343). The surfaces of the outer wall frame (342) and the inner wall frame (343) are hollowed out with a plurality of rectangular through grooves. A partition (344) is welded on the upper and lower sides of the middle between the outer wall frame (342) and the inner wall frame (343). Each The upper surface of the second partition (344) is provided with a plurality of evenly distributed through holes extending downwards, and a second mounting foot (341) is welded on the outer side of the lower end of the outer wall frame (342). The outer wall frame (342) is fixedly connected to the upper side of the first air cooling component (510) through the second mounting foot (341) screws, and a second clamping groove is provided on the upper and lower sides between the outer wall frame (342) and the inner wall frame (343). The second mounting frame (340) is movably clamped with the left and right ends of the first cooling pipe group (350) and the left and right ends of the second cooling pipe group (360) through the second clamping groove, and the second mounting frame (340) does not directly contact the single battery cell (630); A plurality of mounting frames (330) are mounted between the front end and the rear end of the cooling tube group (350) and the front end and the rear end of the cooling tube group (360). The mounting frame (330) includes a mounting foot (331), an inner wall plate (332), an outer wall plate (333) and a partition plate (334). A plurality of partition plates (334) are welded between the inner wall plate (332) and the outer wall plate (333). Both the inner wall plate (332) and the outer wall plate (333) are arc-shaped structural plates. The upper and lower sides of the inner wall plate (332) and the outer wall plate (333) are connected to each other. A card slot 1 is provided on each side, and the mounting frame 1 (330) is movably connected with the front end and rear end of the cooling tube group 1 (350) and the front end and rear end of the cooling tube group 2 (360) through the card slot 1. The mounting frame 1 (330) does not directly contact the single battery cell (630). The outer wall plate (333), the inner wall plate (332) and the partition plate 1 (334) are all honeycomb plates. A mounting foot 1 (331) is welded on the outer side of the lower end of the outer wall plate (333). The mounting frame 1 (330) is fixedly connected to the upper surface of the air-cooling component 1 (510) through the mounting foot 1 (331); The upper end of the mounting frame 1 (330) and the upper end of the mounting frame 2 (340) are both flush with the upper surface of the cooling pipe group 1 (350).
