The invention relates to a heat dissipation device for a charge-discharge motor of an electric vehicle and the charge-discharge motor adopting the heat dissipation device. The heat dissipation device comprises a shell, a first air inlet module, a second air inlet module, an air outlet module, a module mounting cover plate and a charge-discharge motor module, wherein the first air inlet module and the second air inlet module are located on the upper left portion and the upper right portion of the shell correspondingly, and the first air inlet module and the second air inlet module are the same in structure; external air enters the heat dissipation device from the first air inlet module and the second air inlet module; the air outlet module is located at the bottom of the shell, and air entering from the air inlet module is discharged out of the heat dissipation device from the air outlet module; the charging and discharging motor module is located in the shell, and an independent air channel is formed in the air inlet through the module installation cover plate. The heat dissipation device is provided with an efficient ventilation and heat dissipation structure, reliable heat dissipation performance is achieved in a compact structure, and the overall protection grade of the charging and discharging motor with the structure is not lower than IP54.
Description
technical field [0001] The invention relates to the technical field of charging and discharging devices for new energy vehicles, in particular to a cooling device for charging and discharging motors of electric vehicles and a charging and discharging motor using the same. Background technique [0002] Under the guidance of the national carbon peak carbon neutralization strategy, the new energy industry is booming. The demand for electric vehicle charging is increasing day by day. The traditional electric vehicle charger only has the charging function, and the electric energy can only flow from the grid to the electric vehicle energy storage battery. However, the new type of charging and discharging machine can flow bidirectionally from the grid to the electric vehicle energy storage battery. , can play a role in stabilizing the power grid; at the same time, reasonable re-discharging of the electric vehicle energy storage battery is beneficial to the health of the battery and...
