Brief description of thermal pad

As we all know, when using a computer, if you want to pay attention to the temperature change, you must first pay attention to the temperature change of the computer CPU. If the temperature of the CPU is too high, the running speed of the computer will drop, and the computer may crash to protect the CPU from damage, so People will install a cooling fan to conduct the excess temperature of the CPU to the outside, thereby reducing the temperature of the CPU when it is running.

Generally speaking, the higher the power of electronic components, the more heat they generate, and today's technological development is pursuing high frequency and high speed, resulting in a large amount of heat generated when electronic equipment is running. Most of the heat generated by electronic equipment is Waste heat, and the accumulation will make the local temperature too high, so people will conduct the excess heat of the equipment to the outside through the heat dissipation device.

Although the heat dissipation device and the heat source in the electronic equipment seem to fit closely, there is still a large uncontacted area between the two under actual microscopic observation, and the heat cannot form an effective heat flow channel during conduction, thus making the heat dissipation of the electronic equipment The effect is not as expected, which is why a thermally conductive silicone gasket is used to fill the gap between the two.

Thermal pad is one of many thermally conductive materials, and it is also one of the most commonly used thermally conductive materials on the market. Air, so that heat can be quickly conducted to the heat dissipation device through the thermal pad, so as to ensure that the electronic equipment can be used at a suitable temperature for a long time.
