Laptop fever source and Solution

The birth of notebook makes it easy for more friends who often go out. Many features such as lightweight and portable are not available on desktops. However, the volume and noise of the machine limit the heat dissipation system of the notebook, which makes the heat dissipation of many laptops not ideal. Especially in summer, some unpleasant things may occur due to heat dissipation. Therefore, the Auxiliary Heat Dissipation of the notebook seems to be more important.

Because the power consumption and heat consumption of the desktop CPU are relatively large, using it in the notebook will lead to some unpleasant things in the notebook due to poor heat dissipation, so the mobile processor specially designed for the notebook is born. Many notebook CPU processors consume more than 20 W of power, especially the mobile Pentium 4 processor. Although many technologies make the average energy consumption of the entire notebook very low, however, the peak value during use is still very high, with more than 30 million organic resources. Much of the energy consumed will become heat-emitting.

The main heat dissipation of the notebook is of course from the CPU, which is a hot user. However, in the notebook, the CPU heat is not the whole notebook heat. In addition, the CPU processor heat is not very large in the early days. Simply using a simple passive heat dissipation method can satisfy the heat dissipation needs of the machine, that is, the heat sink that everyone is familiar. However, with the continuous upgrade of the CPU processor, the heat dissipation demand of the processor is very urgent after the Pentium III processor era.

Second, the video card heat also accounts for a large proportion, the early video card heat is not very large, however, many high-end machines often configure good graphics such as ATI mobility radeon 9600 or geforce 4 5600 go, so the heat also increases a lot. Then, some other hot accessories, such as memory, hard disk, and battery, are also some sources of notebook heat.

Introduction to notebook Heat Dissipation

1. Fan cooling. Currently, one of the heat dissipation methods of many laptops is caused by fan cooling. The fan is divided into two types: axial fan and radial fan. In general, the axial fan, the cost is low, the air volume can be adjusted as needed, but the occupied volume is relatively large, it is impossible to make the notebook very thin. The other radiation fan has thin blades, good airflow direction, no eddy current, and small footprint. However, the cost is relatively high, but most laptops are widely used, mainly considering reducing the size of the notebook.

2. heat pipe heat dissipation. Heat Pipe Cooling was initially introduced by IBM. Because the heat pipe is more suitable for machines with small volume space, short time heat dissipation, and small space near the heat source, heat pipe cooling technology is increasingly used in laptops.

3. Double fan cooling. Such a heat dissipation method often appears on some machines with strong performance. A fan must be used to heat the CPU, the other is to heat the data in different places based on different machine conditions. Some machines heat the graphics card, and some machines still serve the CPU. The dual-fan design saves power, because a single fan must use high power, and the dual-fan does not need to, so that noise can be reduced. The CPU uses a dual-fan, which only requires a low-power fan and runs Based on the heat, resulting in lower noise and prolonged service life.

4. Heat Dissipation through the machine itself. Some ultra-thin machines cannot install the fan for heat dissipation due to their own volume restrictions, so they use their own components for heat dissipation, use the keyboard to assist in heat dissipation and the machine metal shell to distribute the internal heat of the machine.

External Auxiliary Heat Dissipation Products

Although there are already good auxiliary heat sink devices in the notebook, many laptops will still undergo severe tests in the hot summer. Some machines will suffer from excessive heat, and a "miserable event" such as burning CPU ". Therefore, if we can add external Auxiliary Heat Dissipation products, we believe that our book will surely survive a cool summer.

Currently, there are not many laptop heat dissipation products on the market. Generally, we can see such products as the fan base for the notebook and the liquid Heat Sink base for the notebook.

The price of the fan base for the notebook is relatively low in the heat dissipation products of the notebook, which can be bought in dozens of Yuan. It is powered by a USB interface. There are two fans on the base. Connect the power source and plug in the USB cable. The fan will start to run, so that the notebook and the desktop can be isolated, use a fan to distribute the heat at the bottom of the notebook to the space of the base, so that you can avoid the heat conduction of the notebook on the table, without causing the bottom of the notebook to be very hot.

Notebook dedicated Liquid Heat Sink base: This type of heat sink base is expensive in terms of price, generally around 100 yuan, it through the dedicated coolant inside, quickly absorb the heat at the bottom of the notebook, let the heat be quickly distributed out in a short time.

There is no special base for well-known brands on the market, but recently I have seen a new portable radiator named "light cavalry" launched by cool. It adopts active heat dissipation, and uses the gap between the bottom of the notebook and the hot plate to generate convection with a low noise fan and heat sink to achieve heat dissipation.

In addition to these professional notebook radiators, Xiao Bian also recommends a non-dedicated heat sink product that can be purchased in any supermarket at a price of over a dozen yuan, this is the ice bag that people often put on chairs in summer. It turns into a liquid in case of heat, and the heat dissipation effect on the notebook is also very good. I have been using this ice bag to heat my notebook.

In fact, if a laptop fails, the cost of service is also very good. However, if you can maintain it well, I believe it can save a lot of maintenance fees. heat dissipation is also a noteworthy problem, so in summer, you must make your book cooler.
