Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a heat dissipation device for a battery system of a new energy vehicle. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new vehicle power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. There are slight differences depending on the type of electric vehicle. In pure electric vehicles equipped only with batteries, the role of the battery is the only power source for the vehicle drive system. In hybrid vehicles equipped with traditional engines and batteries, the battery can play the role of both the main power source of the vehicle drive system and the auxiliary power source. It can be seen that at low speeds and starting, the battery plays the role of the main power source of the vehicle drive system; when accelerating at full load, it plays the role of an auxiliary power source; when driving normally or decelerating or braking, it plays the role of storing energy.

[0003] Most of the existing new energy vehicle battery cooling devices use cooling fans to achieve air exchange in the battery pack casing. However, the air flow direction of this cooling method is fixed, which easily causes heat accumulation in a certain place in the casing. This defect will still cause heat accumulation in the battery. When cooling the battery, the heat accumulation area cannot be effectively cooled, thereby reducing the cooling effect of the device. Summary of the invention

At the same time, the servo motor 18 is started, and the servo motor 18 drives the semicircular gear 17 to make the linkage gear 13 rotate intermittently, so that the filter cartridge 14 rotates intermittently to prevent the outside of the filter cartridge 14 from always facing the gas inlet end. While the filter cartridge 14 rotates, the outside of the filter cartridge 14 is cleaned by the cleaning brush roller 15 to avoid blockage.

[0040] Working principle: when the battery body 7 is in use, the pump body 407 is started, the pump body 407 extracts air, and then transmits it to the inside of the hollow rotating circular tube 413 through the delivery pipe 409, and then transmits it to the hollow arc-shaped air-blowing seat 425 through the metal telescopic tube 427, and the heat generated by the battery body 7 during use is dissipated through the air-blowing holes on the hollow arc-shaped air-blowing seat 425, the gas is preliminarily blocked by the partition 10, and the gas is preliminarily filtered by the filter cartridge 14 to prevent dust in the gas from polluting and damaging the battery body 7, and the servo motor 18 is started at the same time, and the semicircular gear 17 is driven by the servo motor 18 to make the linkage gear 13 rotate intermittently, so that the filter cartridge 14 rotates intermittently to prevent the outside of the filter cartridge 14 from always facing the air inlet end of the gas, and while the filter cartridge 14 rotates, the outside of the filter cartridge 14 is cleaned by the cleaning brush roller 15, and the drive motor 416 is started, and the rotating gear 13 is driven by the drive motor 416 The mounting plate 414 rotates, so that the hollow arc-shaped air-blowing seat 425 on the rotating mounting plate 414 moves in a circle. When the rotating mounting plate 414 rotates, the adjusting gear 421 at the top of the rotating mounting plate 414 rotates in the limit position of the limit scallop frame 411, so that the rotating cylinder 420 drives the pushing circular plate 422 so that the reciprocating pushing rod 424 drives the hollow arc-shaped air-blowing seat 425 to move horizontally back and forth in the slide groove opened on the rotating mounting plate 414. At the same time, the electric driving rod 405 drives the tooling moving plate 403 to move horizontally back and forth outside the guide cylinder 402, so that the heat generated by the battery body 7 is evenly dissipated. While dissipating the heat, the temperature monitoring meter 426 on the hollow arc-shaped air-blowing seat 425 monitors the heat generated by the battery body 7. When it is detected that heat is accumulated in the area, the driving motor 416 and the electric driving rod 405 are stopped, and the area is effectively dissipated through the hollow arc-shaped air-blowing seat 425.
