Electric automobile cooling and flame retardant mesh system

Abstract

The invention discloses an electric automobile cooling and flame retardant mesh system. The electric automobile includes a cell pack. The electric automobile cooling and flame retardant mesh system includes an insulation oil pipeline, a casing arranged outside the cell pack and an oil pump, wherein the insulation oil pipeline is provided with an insulation oil tank, the top of the insulation oil tank is provided with a cooling device, and the insulation oil direction of the insulation oil pipeline is provided with a circulating flowing through tank, an oil pump and the insulation oil tank. Thesystem is advantaged in that through setting the casing outside the cell pack, heat of the cell pack is taken away by the insulation oil through the casing, and the work temperature of the cell in operation is guaranteed; through setting the cooling device at the top of the insulation oil tank, heat exchange between the insulation oil tank and the cooling device is performed, temperature reduction of the oil in the insulation oil tank is continuously realized, and the heat of the insulation oil is radiated outside by the cooling device; a flame retardant mesh is arranged between the cell packand the casing, hollow glass micro balls are internally arranged, bump force can be buffered by the mesh, the vibration avoidance effect of the cell pack is improved, when the cell pack is combusted,flame retardant performance and safety performance of the cell pack are improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle cooling and flame-retardant mesh system. Background technique [0002] The electric motor is used as the direct power source in the electric vehicle. In order to ensure the normal operation of the motor, it is necessary to effectively cool the motor unit. Generally, a motor unit of a pure electric vehicle includes a drive motor and a motor controller, and a motor unit of a plug-in hybrid electric vehicle additionally includes a generator. In addition, pure electric vehicles or plug-in hybrid vehicles need to be charged when the battery power is insufficient, and the charging unit including the charger also needs to be cooled during the charging process. Batteries are often cooled with coolant to remove excess thermal energy through heat exchange and heat dissipation to the atmosphere. The temperature of the working environment of the battery affect...
