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.

    本发明涉及一种电动汽车充放电机散热装置及采用其的充放电机,包括壳体、第一进风模块、第二进风模块、出风模块、模块安装盖板和充放电机模块;其中,所述第一进风模块和第二进风模块分别位于所述壳体的左上部和右上部,所述第一进风模块和第二进风模块的结构相同;外部空气从所述第一进风模块和第二进风模块进入该散热装置;所述出风模块位于所述外壳的底部,从进风模块进入的空气从所述出风模块排出该散热装置;所述充放电机模块位于所述壳体内部,并通过所述模块安装盖板使得进风口形成独立风道。本发明散热装置具有高效的通风散热结构,在较为紧凑的结构中实现可靠的散热性能,并使具有该结构的充放电机整体的防护等级不低于IP54。
