Automotive Auto Radiator is an indispensable part of the cooling system of automotive water-cooled engine. At present, it is developing in the light, efficient and economical direction. Auto Radiator structure is also constantly adapt to the new development, the most common form of Auto Radiator can be divided into two types of DC and cross flow.

Auto Radiator core structure of the main form of tube and tube with two major categories. Segmental radiator core is composed of many fine cooling tube and heat sink, cooling pipe mostly use flat circular cross section to reduce air resistance, increase the heat transfer area.

Radiator core should have a sufficient flow area, so that coolant through, but also should have enough air flow area, so that sufficient air to take the coolant to the heat sink heat. At the same time must also have enough heat dissipation area to complete the heat exchange between the coolant, air and heat sink.

Tubular Auto Radiator is made of corrugated radiator and cooling tube, and the heat dissipation area can be increased by about 12% under the same conditions as the tube radiator. A well-like louver hole with a disturbing airflow on the radiator to disrupt the attachment of the flowing air to the surface of the radiator to improve the heat dissipation capacity.
