The invention relates to the field of controller heat dissipation, in particular to a new energy automobile motor controller heat dissipation method which reasonably selects air cooling heat dissipation or liquid cooling heat dissipation according to the external environment so as to quickly control the actual temperature of a motor controller to be below a threshold temperature, and then the heat dissipation capacity of a heat dissipation module is further adjusted so as to improve the heat dissipation efficiency of the motor controller. The heat production efficiency of the motor controller and the heat dissipation efficiency of the heat dissipation module are balanced, so that the temperature of the motor controller is kept stable, the temperature fluctuation in the heat dissipation process is reduced, fault judgment and alarm are carried out under the condition that cooling and heat dissipation are failed, the cost is reduced, the heat dissipation and temperature control effects are good, and the equipment operation reliability is high. The heat dissipation strategy is reasonable and efficient.
