A large number of integrated circuits are used in notebook accessories. As we all know, high temperature is the enemy of integrated circuits. High temperature will not only cause unstable operation of the system, shorten the service life, and may even burn out some parts. The heat that causes high temperatures does not come from outside the computer, but inside the computer, or inside the integrated circuit.

　　The role of the radiator is to absorb the heat, and then radiate it into the case or outside the case to ensure that the temperature of the computer components is normal. Most radiators absorb heat by contacting the surface of the heating component, and then transfer the heat to a remote place through various methods, such as the air in the case, and then the case transfers the hot air to the outside of the case to complete the heat dissipation of the computer. There are many types of radiators. CPU, graphics card, motherboard chipset, hard disk, chassis, power supply and even optical drive and memory all need radiators. These different radiators cannot be mixed, and the most common one is the CPU radiator. .　　

　　According to the way in which heat is taken away from the radiator in the notebook accessory, the radiator can be divided into active heat dissipation and passive heat dissipation. The air-cooled radiator is common in the former, and the heat sink is common in the latter. Further subdivide the heat dissipation methods, which can be divided into air cooling, heat pipe, liquid cooling, semiconductor refrigeration, compressor refrigeration and so on.　　

In the hot summer, when we are playing with the computer, eating ice cream, and enjoying the coolness that the fan or air conditioner brings to us, the computer on the side must be very angry. If the computer can talk, I think it will scold you because of you. Regardless of its "life or death", it is also very hot and uncomfortable. Computer radiators are very useful for computers. We often hear many friends say that their motherboards, hard drives, or CPUs burn out in summer. One of the common reasons is that they do not properly dissipate heat.
