Auto parts radiator belongs to automobile cooling system. The radiator in the engine water cooling system is composed of three parts: water inlet chamber, water outlet chamber, main fin and radiator core. 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 from the coolant, so the radiator is a heat exchanger.
In order to prevent the engine from overheating, the parts around the combustion chamber (cylinder liner, cylinder head, valve, etc.) must be properly cooled. In order to ensure the cooling effect, the automobile cooling system generally consists of a radiator, a thermostat, a water pump, a cylinder water channel, a cylinder head water channel, and a fan. The auto parts radiator is responsible for the cooling of circulating water. Its water pipes and radiating fins are mostly made of aluminum. The aluminum water pipes are made of flat shape and the radiating fins are corrugated. Pay attention to the heat dissipation performance. The installation direction is perpendicular to the direction of air flow. The wind resistance should be small and the cooling efficiency should be high.
Auto parts radiator is an indispensable and important component in automobile water-cooled engine cooling system. At present, it is developing in the direction of light weight, high efficiency and economy. The structure of automobile radiator is constantly adapting to new developments. The most common structural forms of automobile radiators can be divided into two types: DC type and cross-flow type.
The structure of the core of the radiator is mainly divided into two types: tube-fin type and tube-band type. The core of the fin-type radiator is composed of many thin cooling tubes and fins, and most of the cooling tubes have an oblate cross section 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 auto parts radiator.
The auto parts radiator has an irreplaceable important role in auto parts, and maintenance is essential. 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 the corrugated radiating belt and the cooling tube alternately. Compared with the tube and fin type radiator, the tube and strip 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 side improves the heat dissipation capacity.
