Automotive radiators are generally divided into water and air cooling.

     The heat dissipation of an air-cooled engine relies on the circulation of air to remove heat to achieve heat dissipation. The outside of the cylinder of the air-cooled engine is designed to be a dense sheet-like structure, thereby increasing the heat dissipation area to meet the heat dissipation requirements of the engine. Air-cooled engines have the advantages of light weight and easy maintenance compared to the most used water-cooled engines.

     Water cooling is the radiator of the water tank that is responsible for cooling the coolant with high temperature of the engine; the task of the pump is to let the coolant circulate throughout the cooling system; the operation of the fan is directly blown to the radiator by the ambient temperature, so that the temperature inside the radiator The coolant is cooled; the thermostat controls the state of the coolant circulation. The reservoir is used to store the coolant.

     When the vehicle is running, dust, leaves, and debris can easily accumulate on the surface of the radiator, and blocking the heat-dissipating blades causes the performance of the radiator to decrease. In this case, we can use a brush to clean it, or use a high-pressure air pump to blow away the debris on the radiator.
