The invention discloses a vehicle model identifier with a radiating device. The vehicle model identifier can be used under high-temperature severe environments, the internal temperature of the vehicle model identifier provided with a light curtain sensor can be automatically controlled, and the light curtain sensor can be normally and stably used. The vehicle model identifier comprises a shell, the light curtain sensor, a cover plate, a fan, a temperature sensor, a power supply, a controller, a double-piezoelectric film sensor, a supporting rod and a base, wherein the temperature sensor detects the internal temperature of the shell; the controller compares a measured temperature value with a preset threshold value; if the measured temperature value is greater than the preset threshold value, the power supply of the fan is turned on, the fan rotates, the temperature is reduced, and the light curtain sensor can be used at an appropriate temperature.
