Types and characteristics of materials for automobile radiators
1.Aluminum alloy radiator
The aluminum alloy radiator is one of the most widely used radiators on the market, and is made of pure aluminum as a whole. It has the advantages of light weight, good thermal conductivity, and low cost, so it is widely used in various types of automobiles.
The disadvantage of the aluminum alloy radiator is that its strength is relatively low and it is easy to deform.
The advantages of aluminum profile radiators are reflected in the following aspects: low production cost, high cost performance; relatively mature production process, high production capacity; good thermal conductivity of aluminum profiles, good heat dissipation performance; good oxidation and corrosion resistance of aluminum profile radiators , good environmental adaptability; aluminum radiators are widely used in various types of cars because of their superior performance
2.Copper-aluminum composite radiator
The copper-aluminum composite radiator is a composite radiator. The surface is made of aluminum profiles, and aluminum has good heat dissipation performance. In addition, the column-wing structural design increases the heat dissipation area, allowing the radiator to achieve rapid heat dissipation and temperature rise. Fast and other performance.
The advantages of copper-aluminum composite radiators are reflected in the following aspects: long life; good comprehensive mechanical properties; wide applicability; economy and decoration
3.Plastic radiator
Plastic heat sinks are light in weight, highly plastic in appearance, and low in cost, and are favored by many manufacturers. However, compared with radiators made of metal alloys, its thermal conductivity is not stable, and its thermal conductivity varies greatly. It cannot ensure that it can adapt to the working environment well, and it may even deform after working for a long time.
4.Stainless steel radiator
Stainless steel radiator is a high-grade radiator material, which has the advantages of corrosion resistance, high strength, etc., can withstand high temperature and high pressure, and has a long service life. But because of its high cost, it is used in high-end cars.
Manufacturing process and process of automobile radiator
1.Material preparation and cutting:
First of all, you need to prepare the materials needed for the radiator, usually aluminum alloy or plastic. Then, the material is cut into the desired shape and size.
2.Stamping and Forming:
Next, the material is put into a stamping machine to be shaped. The punch presses the material into the desired shape and punches holes in it.
3.Welding and Brazing:
The individual parts of the heat sink are then welded or brazed. These components include heat sinks, water tanks, water inlet and outlet pipes, etc.
4.Surface treatment and spraying:
Finally, the radiator is finished and painted. Surface treatment can improve the corrosion resistance and aesthetics of the radiator. Spraying can add a protective film to the radiator to prevent it from being damaged.
Quality control and detection method of automobile radiator
1.Visual inspection and dimension measurement:
First, a visual inspection and dimensional measurement of the radiator is required. The visual inspection can check whether the surface of the radiator is flat, whether there are cracks, bubbles and other defects. Dimensional measurement can check whether the size of the radiator meets the requirements.
2.Air tightness test and pressure test:
Next, the radiator needs to be tested for air tightness and pressure. The air tightness test checks the radiator for air leaks. The pressure test can check the working state of the radiator under high temperature and high pressure.
3.Corrosion resistance test and durability test:
Finally, the radiator needs to be tested for corrosion resistance and durability. The corrosion resistance test can check whether the radiator can be used for a long time in harsh environment without being corroded. Durability testing can check the working condition of the radiator after long-term use.
Conclusion
