What is a heatsink and how does it reduce the temperature of computer parts?
One of the most important problems of electronic components is the generation of heat, which creates many challenges for them. In this situation, the sink sink comes into action, which can absorb the heat produced by the part, and as a result, the temperature of the desired part decreases. But what exactly is a heat sink and how does it work?
How is heat generated in electronic devices?
There are many different gadgets and electronic devices around us now. There is. All these devices consist of thousands of small and large parts that require electrical power to work. Although part of this electricity is used to operate the device, the rest of the energy (depending on the optimal use of the device) is wasted as heat.
These devices cannot keep heat inside their body and must be Somehow get rid of this production heat. A heat sink is used for this purpose.
What is a heat sink?
In simple words, a heat sink is a part that is embedded in the necessary computer parts and due to the use of conductive materials, it can absorb heat well. Then this energy is transferred to the outside environment through convection and other methods.
Heat sink mechanism
Heat sinks are made of thermally conductive materials (usually aluminum). be. Compared to other thermally conductive materials such as silver and gold, aluminum is a much cheaper metal.
The heat of a relatively small electronic enclosure is absorbed by a flat metal plate through conduction. To facilitate this process, a thermal paste is usually placed between the outer casing of the electronic device and the heatsink. By using these types of pastes, these two parts can have better physical contact.
A heat sink With minimal diffusion resistance, it ensures that heat is distributed almost evenly across the plate and fins. Of course, what should be the size of the heat sink according to the heat produced, is a very complicated issue that we cannot deal with in this article.
On the other side of the heat sink, metal fins are used for better heat transfer. . There is a gap between the fins so that the air flows through it and as a result the heat of these fins decreases.
Natural cooling against the use of fans
But if using a fan, the speed This process becomes much more, and as a result, the heat produced gets out of the computer case at a faster rate. Computers are vital and without them, you will face many problems. Although in this article we discussed the heat sinks in computers, the same approach is used in other electronic devices and they may use different approaches in some details.
As we said for heat sinks in computers, Silicone thermal paste is so important that it is better to replace the used paste every once in a while. Fortunately, you can choose from dozens of different thermal pastes in SafirSoft. To view these products, you can click on the link below.
