The source and solution of the heating of notebook computer _ hardware Maintenance

The birth of the notebook is convenient for more often go out of friends, lightweight, portable and so many of these features are desktop can not have. However, the size and noise of the machine limit the thermal system of the notebook, which makes the heat dissipation part of many notebooks not ideal, especially in summer, because there will be some unpleasant things about the heat dissipation. So, the auxiliary cooling of the notebook seems to be more important.

Notebook fever source

Because of the high power and calorific value of the desktop CPU, the use of the notebook will cause some unpleasant things to happen because of the bad heat, so the mobile processor designed for the notebook is born. Many notebooks have a CPU processor that consumes more than 20W of power, especially mobile Pentium 4 processors, although there are many technologies that make the average energy consumption of the entire notebook low, but the peak is still high at the time of use, more than 30W organic. Many of the energy consumed will be turned into heat emitted.

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. But as the CPU processor continues to escalate, the need to heat the processor from the time of entering the Pentiumⅲ processor is compelling.

Second, the graphics card also accounted for a large proportion of calories, the early video card heat is not very big, but now many high-end machines are often configured ATI Mobility Radeon 9600 or GeForce 4 5600 go such a good video 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. The fan is 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 cooling. 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. Dual 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.

External Auxiliary Cooling Products

Although the notebook has a good auxiliary cooling device, but in the hot summer, many notebooks will still be severe test by the scorching sun, some machines will be because of excessive heat, and the burning of the CPU, such as "tragic events." Therefore, if you can add external auxiliary cooling products, I believe that our books will be a cool summer.

Now the market is not a lot of notebook cooling products, generally you can see: Notebook dedicated fan heatsink base, notebook liquid cooling base and so on.

Notebook dedicated fan heatsink base price in the notebook cooling products is a relatively inexpensive, generally at dozens of yuan can be bought. It is powered by a USB interface, there are 2 fans on the base, connect the power supply, plug in the USB cable, the fan will start to operate, so you can isolate the notebook and the desktop, through the fan to the bottom of the notebook heat to the base of space, so you can avoid the notebook on the table on the heat, Won't cause the bottom of the notebook to be very hot.

Notebook dedicated liquid Cooling base: This type of radiator base in the price is more expensive, generally around 100 yuan, it through the special coolant inside, quickly absorb the bottom of the notebook heat, so that the heat in a short time quickly distributed out.

Now there is no special well-known brand of the base, but recently the author in the market saw a cool new launch of the "Light Horse" notebook dedicated radiator. It uses the active heat dissipation, utilizes the gap between the bottom of the notebook and the heat sink, generates convection with the low noise fan, and combines the heat sink to achieve the heat dissipation purpose.

In addition to these professional notebook radiator, small series also recommend a any supermarket can buy the non-dedicated heat products, the price is more than 10 yuan, which is often used to put on the chair in summer ice packs. It becomes liquid inside the heat, the thermal effect of the notebook is also very good oh, I have always used this ice pack to my laptop heat.

In fact, a notebook if a fault, maintenance costs are also very good, but if you can maintain, I believe you can save a large amount of maintenance costs, cooling is also a worthwhile concern, so the summer must make your laptop more cool.
