Automobile radiator is an indispensable and important component in automobile water-cooled engine cooling system, and it is developing in the direction of lightness, efficiency and economy. The structure of automobile radiator is constantly adapting to new developments.
The core of the fin-type radiator is composed of many thin cooling tubes and fins. Most of the cooling tubes use oblate cross-sections to reduce air resistance and increase heat transfer area.
The core of the radiator should have enough flow area for the coolant to pass through, and at the same time, it should have enough air flow area to let enough air pass to take away the heat transferred from the coolant to the radiator. At the same time, it must have enough heat dissipation area to complete the heat exchange between the coolant, air and the heat sink.
The tube-belt radiator is formed by welding a corrugated radiating belt and a cooling tube arranged alternately.
Compared with the tube and fin type radiator, the tube and band radiator can increase the heat dissipation area by about 12% under the same conditions. In addition, there are louver-like holes on the heat dissipation belt that disturb the airflow to destroy the flowing air on the surface of the heat dissipation belt. The adhesion layer on the upper surface improves the heat dissipation capacity.
