At present, electric car radiators are generally made of aluminum alloy. The water pipe and heat sink are mostly made of aluminum. The aluminum water pipe is made into a flat shape with a corrugated heat sink. The heat dissipation performance is emphasized. The installation direction is perpendicular to the direction of air flow. , Try to make the wind resistance as small as possible, and the cooling efficiency should be high. The coolant flows in the radiator core, and the air passes outside the radiator core. The hot coolant becomes cold by dissipating heat to the air, and the cold air heats up by absorbing the heat dissipated by the coolant, and heat dissipation is achieved through the overall circulation.
As the electric vehicle radiator is an important component of the automobile water-cooled engine cooling system, and with the development of the automobile market in my country, the electric vehicle radiator has also begun to develop in a light, cost-effective and convenient direction. Radiators are mainly divided into two types: DC type and cross-flow type. The structure of the core of the heat exchanger has two types: tube-sheet type and tube-band type. The core of the fin-type radiator consists of many thin cooling tubes and fins. The cooling tube adopts an oblate cross section to reduce air resistance and increase heat transfer area.
