What Is The Structure Of The Radiator?

There are many kinds of radiators, such as automotive radiator, industrial radiator, finned radiator, and so on.
In the automobile cooling system, the main components of the radiator include: radiator core, water inlet chamber, water outlet chamber and main plate. The structure of radiator core is mainly divided into two types: tube-type and tube-type. The tube-and-band radiator is made of corrugated diffuser and cooling pipe arranged alternately and welded. Like the shutter, the cooling belt also has small holes that disturb the airflow, which are used to destroy the adhesion layer of the flowing air on the surface of the cooling belt, increase the heat dissipation area and improve the heat dissipation capacity. The core of the finned radiator is composed of many thin cooling tubes and fins. Most of the cooling tubes adopt flat circular sections to reduce the air resistance and increase the heat transfer area.
Industrial radiator (referred to as radiator for short, also known as heat sink) is the main equipment in heat exchange devices such as cooling air with refrigerant, heating air with heat medium, or recovering air waste heat with cold water. High temperature water, steam or high temperature heat transfer oil can be used to heat the air, and salt water or low temperature water can be used to cool the air.
Finned radiator can be divided into wound fin type in terms of fin structure; String type; Soldering lug type; Rolling type.
At present, the most widely used is the steel-aluminum composite finned tube, which uses the pressure resistance of the steel pipe and the efficient thermal conductivity of aluminum, and is compounded on a special machine tool. Its contact thermal resistance is almost zero at 210 ℃. The steel-aluminum composite tube has irreplaceable advantages over other finned tube radiators.
