Abstract

The invention discloses a cooling system for new energy automobile battery packs, which relates to the technical field of heat dissipation of new energy automobile battery packs. An installation plateis arranged above a bottom plate, and the bottom plate and the installation plate are fixed by four cylindrical support pillars. A grid of a rectangular structure is arranged by embedding on the upper surface of the installation plate, and a box body is fixed at the position of the grid above the installation plate. The cooling system is novel in design, has an obvious effect, realizes automaticheat dissipation without excessive interference by people, and ensures that new energy batteries are at a safe operating temperature. Safety protection is added, and potential safety hazards are reduced. A mode of heat dissipation based on a heat dissipation fan and a mode of heat dissipation based on a water cooling system are adopted. A control system decides which mode of heat dissipation is started according to two set temperature thresholds, and energy is saved. The two modes can be combined for heat dissipation of batteries in summer, and the cooling effect is maximized.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of battery packs of new energy vehicles, in particular to a cooling system for battery packs of new energy vehicles. Background technique [0002] Hybrid electric vehicles and electric vehicles include a battery pack that compensates or supports the vehicle's powertrain during operation. The battery pack typically requires cooling. The cooling system may include fans that direct air away from the battery cells and / or modules in the battery pack. [0003] After searching, the Chinese patent discloses a battery pack cooling system which is a component composed of two boards. The cell unit of the cold gap is a component composed of two boards, and a box body is arranged outside the cell unit, which is a component composed of two boards. Components, the box body is a component composed of two panels, the front panel is a component composed of two panels, and an air inlet is provided on it, w...
