Vehicle cooling systems have always been an important component of engine life and overall vehicle performance on the road. This is why many radiator companies and radiator suppliers continue to enter the manufacturer world, whether it is the aftermarket or original equipment industry. While driving or operating, heat is generated by all car parts under the hood and spreads to places where it simply cannot be tolerated. With an engine cooling system, a vehicle can eliminate thermal stress and keep the engine temperature in proper operating condition. The radiator wholesaler market is highly competitive.
Included among these components is the radiator. The radiator serves as the heart of the entire cooling system and acts as a heat exchanger. It has these little tubes in which hot coolant flows and is cooled by the radiator motor.
The automotive radiator market size is expected to expand steadily over the coming years as demand for sales and vehicle production increases steadily from many global automakers.
There are three types of radiators available in the global market: copper-brass, plastic, and aluminum. Due to aluminum's natural advantages, heat resistance, lightweight and many other features, radiator manufacturers and radiator wholesalers are now using more aluminum to produce their products. Radiators are generally available in different applications including passenger cars and commercial vehicles ranging from light to heavy duty applications
Heat sink material refers to the specific material used in the heat sink. Each material has different thermal conductivity properties. They are arranged from high to low thermal conductivity, namely silver, copper, aluminum, and steel. However, it would be too expensive to use silver as a heat sink, so the best solution is to use copper. Although aluminum is much cheaper, it obviously does not conduct heat as well as copper (about 50% less). Commonly used heat sink materials are copper and aluminum alloys, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but it is more expensive, difficult to process, too heavy (many pure copper heat sinks exceed the weight limit of the CPU), has small heat capacity, and is easily oxidized. Pure aluminum is too soft and cannot be used directly. Only the aluminum alloy used can provide sufficient hardness. The advantages of aluminum alloy are low price and light weight, but the thermal conductivity is much worse than that of copper. Some radiators take advantage of their own strengths and embed a copper plate in the base of the aluminum alloy radiator. For ordinary users, using aluminum heat sinks is enough to meet heat dissipation needs.
