The invention provides a cleaning method and device for a vehicle heat exchanger and a vehicle. The method comprises the steps that the current running speed of the vehicle and the actual ventilation rate of the heat exchanger of the vehicle are obtained; when the actual ventilation rate is lower than a preset ventilation rate threshold value, the electronic fan is controlled to operate reversely according to the maximum operation power; according to the current running speed and the actual ventilation rate, the target opening degree of an active air inlet grille and the target dynamic pressure boosting pressure of a fan dynamic pressure area are determined; the fan dynamic pressure area is an area corresponding to an air inlet end when the electronic fan runs reversely; and the active air inlet grille is controlled to be opened to the target opening degree, and the dynamic pressure area of the fan is controlled to reach the target dynamic pressure boost pressure, so that the heat exchanger is cleaned. The method can improve the cleaning efficiency of the heat exchanger, ensures that air smoothly passes through the heat exchanger, and improves the cooling effect of the heat exchanger.
