The truck radiator consists of three parts: the water inlet chamber, the water outlet chamber and the radiator core. The coolant flows inside the radiator core, and the air passes outside the radiator. The hot coolant becomes cold by dissipating heat to the air, and the cold air heats up by absorbing the heat radiated by the coolant.
(1) According to the direction of the coolant flow in the truck radiator: the radiator can be divided into two types: longitudinal flow and cross flow types.
(2) According to the structure of truck radiator core: radiators can be divided into tube-fin radiators, tube-band radiators and plate radiators.
(1) The air-cooled engine relies on the circulation of air to take away the heat to achieve the effect of heat dissipation. The outside of the cylinder block of the air-cooled engine is designed and manufactured into a dense sheet structure to increase the heat dissipation area to meet the heat dissipation requirements of the engine. Compared with the most used water-cooled engines, air-cooled engines have the advantages of light weight and convenient maintenance.
(2) Water cooling means the water tank radiator is responsible for cooling the coolant with the engine's high temperature; the task of the water pump is to circulate the coolant in the entire heat dissipation system; the operation of the fan uses the ambient temperature to directly blow to the truck radiator to cool the high-temperature coolant in the radiator; the thermostat controls the state of the coolant circulation, and the liquid storage tank is used to store the coolant.
