The solution to the high temperature of the notebook thermal abnormality

The birth of the

Notebook is convenient for more frequent friends, lightweight, portable, and many of these features are not available to desktops. However, the size of the machine and the noise limit the notebook's cooling system, making a lot of notebook heat dissipation part is not very ideal, notebook temperature is generally high, especially in summer, because the heat will occur some uncomfortable things. So, the auxiliary heat dissipation of the notebook seems to be more important.

Notebook heat source

Due to the power consumption and calorific value of the desktop CPU, the use of notebook, will make the notebook because the heat is not good to occur some unpleasant things, so specifically for the notebook imagined mobile processor was 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 dissipation of the

Notebook is, of course, from the CPU, but in the notebook, the CPU's calories are not the whole of the notebook's calories. And the early CPU processor calorific value is not particularly large, only need to have a simple passive heat dissipation method that can be satisfied with the cooling needs of the machine, which is commonly known as the heat sink heat. However, with the continuous promotion of CPU processors, the processor's cooling requirements are particularly urgent from the time they enter the Pentiumⅲ processor.

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.

Notebook Thermal Introduction

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 very good, no eddy current, occupy a small, but relatively high cost, but most of the notebook is generally used, the main if you consider reducing 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. Double fan cooling. This kind of heat dissipation method often appears inSome of the more powerful machines, a fan is certainly for the CPU cooling service, while the other is based on the machine situation to different places to heat, and some machines are for the video card cooling, and some machines are still CPU services. The imagination of the double fan will be more power, because the single fan must use high-power, double fan is not necessary, so as to reduce the 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 Shopping Guide

Although the notebook has a good auxiliary cooling device, but in the hot summer, many notebooks will be severely tested by the scorching sun, some machines will be too much 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 certainly have 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 particularly hot.
