High thermal conductivity silicone pad is a new product derived from the progress in the heat dissipation adhesive market. It is mainly a kind of thermal conductivity medium material synthesized by a special process with silica gel as the base material and various auxiliary materials such as metal oxides, which is used to reduce the contact thermal resistance between the surface of the heat source and the contact surface of the heat sink. It is specially produced for the design scheme of using the gap to transfer heat, and completes the heat transfer between the heating part and the heat dissipation part. It is an excellent thermally conductive filling material.
The things made of silica gel are still very popular with the public. After all, they are relatively environmentally friendly, and they are very convenient to use, and the price is also particularly appropriate. Therefore, the thermal conductive silica gel film is widely used in various industries. So, what is the reason for the wide application of thermal conductive silica film?
Excellent thermal conductivity
The thermal conductive silica gel sheet is relatively soft, which can be used as a filling pad in many electronic precision mechanical products heat dissipation modules. It is also because of its soft, it is more convenient to use. In addition, silica gel has good thermal conductivity and strong extensibility, so it will gradually expand after being applied to the gap of some small parts, and the gap will be continuously filled, so it will not lose too much heat naturally, so the heat can be well conducted.
Good insulation performance
A lot of electronic products are to use some thermal pad, only in this way can be a good mechanical fixation, but at the same time we have to consider the insulation performance of thermal pad, so that there will be no leakage in the process of use, otherwise it is very dangerous. At this time, because of its insulating properties, silica gel is processed into thermal conductive silicon film, which can be directly applied to the junction of product heat source and radiator.
Low price
Relatively speaking, the cost of thermal conductive silica gel pad is not very high. The extremely thin sheet is very material saving, so the cost of investment is greatly reduced, and the price will gradually decrease. Many people value this advantage and use it in the product cooling scheme!
Environmental protection and safety
At present, the public still pays great attention to safety and environmental protection. Most of the thermal silicone pad is made of silica gel. In addition to adding some environmental friendly glue properly, the thermal pad does not need to add too many other ingredients. Therefore, it is very environmental and safe.
It is worth mentioning that the main purpose of selecting high thermal conductivity silicone pad is to reduce the contact thermal resistance between the heat source surface and the radiator contact surface. The silicone pad with high thermal conductivity can also fill the gap of the contact surface and extrude the air out of the contact surface. Air is a poor conductor of heat, which will seriously hinder the transfer of heat between the contact surfaces; with the supplement of thermal conductive gasket, the reaction on the temperature can reach as small a temperature difference as possible, which can make the contact surface better and fully contact, and truly achieve face-to-face contact.
With the development of science and technology, thermal conductive silicone gasket has been widely used in communication equipment, computer, switching power supply, flat panel TV, mobile equipment, video equipment, network products, medical devices, household appliances, PC server, workstation, optical drive, combo, base station and other fields. In the future, more industrial applications are waiting for the manufacturers to explore and discover.
