Introduction to the car heat sink
Most engines use an internal combustion engine, which works through the heat produced by combustion. But the effective power only accounts for 30%~40% of the total fuel energy, and the remaining energy is consumed as exhaust heat loss and mechanical friction heat loss. In particular, in order to keep the temperature of the cylinder, cylinder head, intake, and exhaust valves moderate, it is necessary to cool the various parts of the internal combustion engine, which will lose heat energy as antifreeze. car heat sink works very well with the aid of antifreeze, dissipating heat energy and thus keeping the internal combustion engine at a moderate temperature. Cooling water is essential for losing heat energy. Most of the water pumps are driven by the engine forcing the cooling water to circulate in various parts of the engine, and the antifreeze absorbs the heat generated by the engine and distributes it to the air. The radiator is the radiator.
working principle
The car heat sink is made by melting the aluminum ingot into a liquid state, filling it into the metal model, and using the die-casting machine to directly die-cast the shape. The heat sink made by die-casting can make the fin into a variety of three-dimensional shapes, and the heat sink can be made according to the demand. It can be formed into a complex shape, and it can also be used to make a heat sink with a diversion effect in accordance with the fan and the direction of the airflow and can make thin and dense fins to increase the heat dissipation area. It is widely used because of the simple die-casting process.
Aluminum heat sink material
The commonly used die-cast aluminum alloy is ADC12, which is suitable for thin castings due to its good die-casting formability, but due to its poor thermal conductivity (about 96 W/m.K), the aluminum radiators in the automotive industry now mostly use AA1070 aluminum material As a die-casting material, its thermal conductivity is as high as about 200 W/m.K, and it has a good heat dissipation effect.
Advantages of Aluminum Die Casting Heat Sinks
The heat sink is integrally formed without interface resistance; thin, dense, or complex-structured fins can be manufactured, which is easy to realize some special designs.
