Integrated circuits are used extensively in computer components. As we all know, high temperature is the enemy of integrated circuits. High temperature will not only cause the system to run erratically, shorten the service life, and may even cause some components to burn out. The heat that causes the high temperature does not come from outside the computer, but from inside the computer, or inside the integrated circuit. The function of the positive radiator is to absorb the heat and then dissipate it into or out of the chassis to ensure that the temperature of the computer components is normal. Most radiators absorb heat by contacting the surface of the heat-generating components, and then transfer the heat to a distance through various methods, such as the air in the chassis, and then the chassis transmits the hot air to the outside of the chassis to complete the cooling of the computer. There are many types of radiators. CPUs, graphics cards, motherboard chipsets, hard drives, chassis, power supplies, and even optical drives and memory all require radiators. These different radiators cannot be mixed, and the most commonly used one is the CPU radiator. . Heat sinks can be divided into active heat dissipation and passive heat dissipation according to the way in which heat is removed from the heat sink. The former is common with air-cooled radiators, while the latter is common with heat sinks. To further subdivide the cooling methods, it can be divided into air cooling, heat pipe, liquid cooling, semiconductor cooling, compressor cooling and so on.
