Background

In northern cold areas, in order to ensure the driving mileage, a pure electric vehicle generally supplies heat to the vehicle through a fuel oil heater and supplies a heat source for a defroster during heating, but in spring and autumn when the air temperature is relatively high, the vehicle does not need to supply heat, and when defrosting is needed, the heat source is also required to be supplied through the fuel oil heater, but the fuel oil heater supplies heat for the whole vehicle, the power is high, and the resource waste is caused only by defrosting.

In addition, the defroster has defrosting and defogging functions simultaneously, but because the temperature difference between the inside and the outside of the electric vehicle is too large, part of water vapor is easy to condense after encountering the cold windshield, so that a layer of fog is formed, if hot air is used for blowing, the temperature difference between the inside and the outside of the vehicle is further aggravated, although the fog can be eliminated, the fog is condensed while the fog is eliminated, so that the speed of eliminating the fog by hot air is slower than that by cold air, and the fog is quickly dissipated as soon as the cold air is opened. The hot air takes effect slowly relatively, generally takes two or three minutes, fog begins to dissipate, but the air inlet of the existing defroster is arranged in the car, the air outlet temperature is relatively high, and the defrosting efficiency is low.
