Notebook Cooling method

The main heat of the notebook, of course, is derived from the CPU of this big fever, but in the notebook, the CPU is not the heat of the whole notebook. And the early CPU processor heat is not very large, only need to have a simple passive cooling mode that can meet the cooling needs of the machine, which is commonly known as the heat sink heat. However, as the CPU processor continues to upgrade, the processor's cooling requirements can be considered very urgent.

Second, the graphics card's heat also accounted for a large proportion of the early graphics card heat is not very big, but now many high-end machines are often configured with a good graphics card, so the heat also followed by a lot of increase. Then, is some other heating accessories, such as memory, hard disk, batteries, etc., but also some sources of calorific value of the notebook.

Introduction to Notebook heat dissipation

1. Fan Cooling. At present, one of the heat dissipation methods of many notebooks is cooled by fans. The fan is divided into axial fan and radiant fan two kinds. Generally speaking, axial type fan, the cost is lower, the air volume can adjust according to need, but occupy the volume is quite big, cannot make the notebook to do very thin. Another type of radiation fan blade is very thin, the airflow direction is good, no Eddy current, occupy a small, but relatively high cost, but most of the notebook is generally used, mainly to reduce the volume of the Notebook.

2. Heat pipe heat dissipation. Heat pipe cooling was first introduced by IBM, because the heat pipe is more suitable for those small space, short time heat dissipation, heat source near the small space machine, heat pipe cooling technology in the notebook more and more to be used.

3. Double fan cooling. Such heat dissipation is often found in the performance of some of the more powerful machines, a fan is certainly for the CPU cooling service, while the other is based on the situation of the machine to different places to heat, and some machines are for the graphics card cooling, and some machines are still CPU services. Dual-Fan design will be more power saving, because a single fan must use high-power, double fan is not necessary, so as to reduce noise. The CPU uses a dual fan that requires a Low-power fan and runs on the basis of heat, with lower noise and longer life.

4. Heat dissipation through the machine itself. Some ultra-thin machines because of their own size limit, unable to install fan cooling, the machine's own parts to dissipate heat, through the keyboard to assist heat dissipation and the machine metal shell of the machine itself inside the heat emitted out.
