The Application Of Radiator

- Feb 07, 2018-

The automobile radiator is an indispensable and important component in the cooling system of automobile water-cooled engine. It is moving in the direction of lightness, high efficiency and economy. Car radiator structure is also constantly adapt to the new development.

The most common car radiator structure can be divided into two types of DC and cross-flow type.

Radiator core structure of the main types of pipe and tube-type two categories. Tubular radiator core is composed of many fine cooling tubes and heat sinks, most of the cooling tube using oblate cross-section, in order to reduce air resistance, increase heat transfer area.

Radiator core should have sufficient flow area, let the coolant through, but also should have sufficient air flow area, let enough air through to take away the heat transfer to the radiator heat.

At the same time must also have sufficient heat dissipation area, to complete the cooling fluid, air and heat exchange between the heat sink.

Tubular heat sink is corrugated heat pipe and cooling pipe arranged by welding.

Compared with the tube-type radiator, the tube-and-tube radiator in the same conditions, the cooling area can be increased by about 12%, the other with a disturbing airflow on the opening of shutter-like louvers to break the flow of air in the surface of the heat sink On the attached layer, improve heat dissipation
