What is the heat dissipation principle of a computer cooler?

For notebook computers, heat dissipation has become the most critical factor in the confrontation between performance and portability, and notebook heat dissipation has always been a bottleneck in the core technology of notebooks. Sometimes laptops crash inexplicably, usually due to high system temperatures. In order to solve this problem, people have designed a heat dissipation base, and a good base can extend the life of the laptop.

The role of notebook cooler is very large, for laptops, in the confrontation between performance and portability, heat dissipation has become the most critical factor, notebook heat dissipation has always been the bottleneck in the core technology of notebooks. Sometimes laptops crash inexplicably, usually due to high system temperatures. To solve this problem, people have designed laptop radiators, and a good radiator can extend the life of your laptop.

The heat generated by the notebook spreads to the outside of the computer faster, does not affect the function of the notebook, and does not corrode the circuits of the computer, so as to ensure the normal operation of the notebook. Radiator material. There are two types of materials used in the main products in the current market:

metal, plastic or wood. The thermal conductivity of metal is good, and most notebooks have anti-slip rubber pads at the bottom, which can increase the friction at the bottom, and it is impossible to protect the notebook and the metal heat dissipation base close together, so the thermal conductivity of metal cannot be fully exerted. Of course, the metal base can better absorb and diffuse the heat that comes out of the laptop.

In addition, metal is generally heavier, and due to the high process requirements during manufacturing, once the workmanship is not fine enough, it is easy to become a sharp weapon to hurt people. Plastic materials are generally lighter and harder, and many engineering plastics are even stronger than metal. For the sake of cost and lightness, notebooks with light weight and low heat can choose a better-designed plastic heat dissipation base.

The heat dissipation principle of the heat dissipation base of the notebook mainly includes: the heat dissipation function is realized simply through the principle of thermal conductivity in physics. The heat dissipation effect can be achieved by placing a heat dissipation base made of plastic or metal on the bottom of the notebook and raising the laptop to promote air circulation and heat radiation.

Install several cooling fans on top of the cooling base to improve the cooling performance. This air-cooled heat dissipation method includes two types: suction and blowing. The difference between the two forms of air supply lies in the difference in the form of airflow, the turbulence generated when blowing is active, which belongs to active heat dissipation, and the wind pressure is large but it is easy to suffer from resistance loss, such as the electric fan we use in daily summer; Laminar flow is generated when suction is generated, which is passive heat dissipation, with low air pressure but stable airflow, such as a case fan.

Heat dissipation is actually a heat transfer process - conduction, convection, radiation and other ways. Usually in desktops, air cooling technology is mainly air-cooled, which includes CPU, graphics card, power supply and chassis cooling fan, etc., in laptops, air cooling is still the main heat dissipation method, and the vast majority of heat dissipation methods are: fan + heat pipe + heat sink combination.

Many laptops on the market use aluminum-magnesium alloy shells, which also play a certain role in heat dissipation. As we all know, there are generally heat vents at the bottom of the laptop, either sucked in or blown out, which are very important for the heat dissipation of the laptop. Laptops are also designed with heat dissipation in mind, and often use feet to raise the fuselage, but when the temperature is too high, it is more reluctant.

Radiators are no strangers to the majority of computer enthusiasts or ownersComputer radiatorsUsually to cool down the CPU and ensure that it is working properly and well, so what is a computer cooler? Which is the best computer cooler? Below we will give you detailed answers, I hope to help you.

What is a PC Cooler?

The function of the computer radiator is to absorb this heat, and then dissipate it into the case or outside the case to ensure that the temperature of the computer parts is normal. Most heat sinks absorb heat by contacting the surface of the heat-generating parts, and then transfer the heat to distant places, such as the air inside 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 heatsinks, CPUs, graphics cards, motherboard chipsets, hard drives, chassis, power supplies, and even optical drives and memory will all need heatsinks, and these different heatsinks cannot be mixed, and the most common contact is the CPU heatsink.

Depending on how heat is taken away from the radiator, the radiator can be divided into active and passive cooling. The former is commonly used for air-cooled radiators, while the latter is common for heat sinks.

What is the principle of a computer radiator? Reputation

The heat dissipation method refers to the main way in which the heat sink dissipates heat. In thermodynamics, heat dissipation is heat transfer, and there are three main ways of heat transfer, heat conduction, heat convection, and heat radiation. The transfer of energy by matter itself or when matter comes into contact with matter is known as heat conduction, which is the most prevalent form of heat transfer.

For example, the way the CPU heatsink base is in direct contact with the CPU to take away the heat is heat conduction. Thermal convection refers to the way in which a flowing fluid (gas or liquid) transfers heat to the tropics, and it is more common in the cooling system of computer cases that the cooling fan drives the gas flow"Forced thermal convection"Heat dissipation. Thermal radiation refers to the transfer of heat by ray radiation, and the most common is solar radiation.

None of these three heat dissipation methods are isolated, and in daily heat transfer, these three heat dissipation methods all occur at the same time and work together. __

Which is the best computer cooler?

1. Air-cooled heat dissipation: Air-cooled heat dissipation is the most common, and it is very simple, that is, use a fan to take away the heat absorbed by the radiator. It has the advantages of relatively low and simple installation, but it is relatively dependent on the environment, such as rising temperatures and overclocking, and its heat dissipation performance will be greatly affected.

2. Liquid cooling heat dissipation: liquid cooling heat dissipation is the use of liquid to forcibly circulate to take away the heat of the radiator under the drive of the pump, which has the advantages of quiet, stable cooling and less dependence on the environment compared with air cooling. But heat pipes and liquid cooled ones are relatively high, and they are also relatively cumbersome to install.

That's all for you, what is a computer cooler? Which is the best computer cooler? All of it.

Computers have entered our households, so when using computers, how do we dissipate heat for computers, let's find out together.

1. Use a fan for computer heat dissipation.

Fans are one of the most effective cooling methods, if the economic conditions allow, you can choose a better fan, desktop fans mainly play the role of exhaust fans and CPU fans, in addition to hard disks, graphics cards and memory can be installed accordingly'Exhaust fans or heatsinks are better for cooling, but some hardware and chassis do not have the conditions to install such fans. Because the heat dissipation performance of the laptop itself is not as good as that of a desktop, it is best to buy a base and crack cooling fan if you use a laptop.

2. Transform the chassis

If the wiring in the chassis is too messy and will interfere with heat dissipation, we need to summarize the wiring of the chassis so that it does not affect the heat dissipation. In addition, if the chassis is too small, it will also cause the hardware to be too close to each other, which will cause the temperature of each hardware to be high, so you might as well replace the large chassis to have better heat dissipation function.

3. Failure to replace hardware

Hardware aging can also cause high temperatures, such as hard disk damage, which can cause the hard disk to be warmer, making the computer slower to use. If you can afford it, you can buy new hardware.

4. Clean up the dust regularly

Dust will seriously affect heat dissipation, especially the dust on the CPU fan, it is recommended to clean it frequently, you can remove the fan to clean it, and the dust on the graphics card and memory module should also be cleaned, and you can use a small brush to brush off the dust.

5. Don't overuse the computer

Using the computer for a long time will definitely make the temperature too high, so it is recommended to let the computer rest for a few hours. And it's good for the body, too. When the computer is not in use, it can also be adjusted to standby moderately, which can reduce the temperature of the computer moderately.

6. Reduce the indoor temperature

In summer, the indoor temperature is too high, which will also affect the heat dissipation of the computer, which can effectively adjust the indoor high temperature, which can reduce the burden on the computer.

7. Don't open too many programs

8. Remove the case cover

When the weather is hot, you may wish to remove the case cover, which can effectively reduce the temperature inside the case, and it is best to blow a fan on the inside of the case.

I don't know if you have noticed,As early as 2006, there was a world's first exhaust radiator,The principle is to take the initiative to quickly extract the heat from the air outlet of the notebook,In principle,It should be a better way to dissipate internal heat dissipation,As for the heat dissipation base type heat dissipation, it is mainly to dissipate the bottom of the notebook。

In my opinion, as long as the base of the laptop is raised, it can approach or achieve the effect of some heat dissipation bases, because it makes the space at the bottom of the laptop larger, and the air circulates more easily, which is convenient for heat dissipation. Some heat dissipation bases use metal materials, of course, the bottom can play a further role in heat dissipation, however, some metals are good at absorbing heat at the bottom of the book, but the heat dissipation is very general, like this. Don't want the heat dissipation base, it's better to pad it yourself, I don't know if you have tested it, how about the cooling effect of the pad and the heat dissipation base?

I now feel that if there is a exhaust radiator + pad, can the best heat dissipation effect be achieved? Regarding the exhaust heat dissipation effect, I have a Pacific Network review link here, although it does not help the external heat dissipation of the notebook, but it has a good cooling effect on the internal hardware.

Notebook thing,The main heat source is actually inside,The internal temperature is a few degrees lower,Even if the external temperature is a few degrees higher (of course, if you are more sensitive to the temperature of the shell, you can't do it,But now it seems that playing games has to be connected to an external keyboard.,It won't touch the notebook)What's the matter? No matter how high the external temperature is, it won't go there, because the internal temperature has dropped, and at most it's the same temperature as a non-exhaust radiator, right? Wouldn't this be more protective of hardware such as CPU graphics cards,So,I want to get a ventilation radiator to try,The key point is,XPS1530The screen is opened at a certain angle,It seems to cover part of the air outlet,I don't know if you can install a ventilation radiator at this time,Will it be blocked and can't be installed?

There is a friend who has used this kind of radiator, and you can give me an opinion?

The following advantages and disadvantages are summarized:

Advantages: 1. Easy to carry, probably the smallest radiator.

2. The cooling effect of notebook hardware is better than that of general radiators, and it is estimated to be more obvious in large-scale games.

Disadvantages: 1 does not help much to the temperature of the shell of this book.

2 Not all notebooks are compatible with installation, this is especially noteworthy.
