A battery heat dissipation device special for a new energy vehicle

Abstract

The invention discloses a heat dissipation device of a battery special for a new energy vehicle, including the base, A fixing frame and two housings are arranged above the chassis, and the fixing bracket is positioned between the two housings, an electric motor is fixed on one side above the base, one end of the electric motor is rotatably connected with a main gear through a rotating shaft, one side of the main gear is meshed with and connected with an auxiliary gear, 11 auxiliary gear are arranged in total, 11 of that auxiliary gear are all fixed with fix rods above, The invention provides Amain gear, Auxiliary gears, blades and shells, the electric motor drives the main gear to rotate through the rotating shaft, The main gear drives the auxiliary gear to rotate, that is, the fan bladedrives the fan blade to rotate, so that the shield shell and the fixed frame are in a vertical state, that is, the fan blade drives the wind direction near the battery body and the gap formed betweenthe fixed frame and the shield shell to blow out, thus forming a certain air flow, and solving the problem that the battery can not be cooled more efficiently.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a special battery cooling device for new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with The power sources of new technologies and new structures of vehicles mainly include lithium-ion batteries, nickel-metal hydride batteries, fuel cells, lead-acid batteries, and supercapacitors. Supercapacitors mostly appear in the form of auxiliary power sources. The main reason is that these battery technologies are still They are not fully mature or have obvious shortcomings. Compared with traditional cars, there are many gaps in cost, power and cruising range. This is also an impo...
