The invention provides a cleaning method and device for a vehicle heat exchanger and a vehicle. The running state of the vehicle is obtained, the air pressure difference between the front end and the rear end of the heat exchanger in the running state is detected, and if the air pressure difference is larger than the preset value corresponding to the running state, the rotating speed and the air outlet direction of a fan are controlled through a strategy corresponding to the running state. The air pressure difference comprises the pressure difference between the front end and the rear end of the heat exchanger. According to the scheme, the fan is arranged on the side, facing the front end of the vehicle, of the heat exchanger of the vehicle, the corresponding strategy is executed according to the running state of the vehicle and the air pressure difference between the front end and the rear end of the heat exchanger, and therefore the rotating speed and the air outlet direction of the fan are controlled, and blockages in the heat exchanger are cleaned; therefore, the purposes of automatically cleaning the blockages on the surfaces of the flat tubes and the fins of the heat exchanger, improving the cleaning efficiency and improving the customer experience are achieved.
本发明提供一种车辆换热器的清理方法、装置及车辆,获取车辆的运行状态,检测运行状态下换热器前后两端的风压差,若风压差大于运行状态对应的预设值,则利用运行状态对应的策略控制风扇的转速和出风方向,对换热器中的堵塞物进行清理,其中,风压差包括换热器前后两端的压力差。在本方案中,通过在车辆的换热器朝向车辆前端的一方设置风扇,根据车辆的运行状态以及换热器前后两端的风压差,执行相应的策略从而控制风扇的转速和出风方向,对换热器中的堵塞物进行清理,从而实现了自动清理换热器的扁管、翅片表面的堵塞物,提高清理效率以及提高客户体验的目的。
