High thermal silicone gasket is a new product derived from the progress in the heat dissipation adhesive market. It is mainly based on silica gel, and various auxiliary materials such as metal oxides are added. A thermal conductive medium material synthesized by a special process , 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, completes the heat transfer between the heat-generating part and the heat-dissipating part, and is an excellent thermal conductive filling material.
Things made of silicone are still very popular with the public. After all, they are relatively environmentally friendly, they are very convenient to use, and the price is particularly suitable. Therefore, thermal silicone pads are widely used in various industries; then, thermal silicone pads are widely used. What’s the reason? Today, CoolThermo will introduce the application principle of high thermal silicone gaskets to you.
Excellent thermal conductivity
You must know that the thermal pads is still relatively soft, and can be used as a filling pad in many electronic precision mechanical product cooling modules. It is precisely because of its softness that it is more convenient to use. In addition, because silica gel is an important raw material, silica gel has good thermal conductivity and strong elongation performance, so it will gradually expand after being applied to the gaps of some small parts, and the gaps will be filled continuously, and naturally it will not be lost. more heat, so that the heat can be well conducted.
Good insulating properties
Since it is used in electronic precision mechanical products, the performance requirements for the materials used are still relatively strict, and insulation is of course essential. Many electronic products need to use some thermal pads, only in this way can the mechanical fixation be done well, but at the same time, the insulating properties of the thermal pads must be considered, so that they will not appear during use. Leakage situation, otherwise it is really quite dangerous. At this time, silica gel, which has insulating properties itself, can show its talents. Because of its insulating properties, it can be processed into a thermally conductive silica gel sheet and can be directly applied to the connection between the heat source of the product and the heat sink.
Not all products that sound high-end are expensive. Some things just look novel. In fact, the price is still acceptable to the public. Silicone is a living example. The cost of thermal pads made from it is still very low. The extremely thin sheet is very material-saving, so the input cost is also greatly reduced, and its price will gradually decrease. Many people value this advantage and use it in product cooling solutions!
Nowadays, the public use items still pay great attention to safety and environmental protection. Most of the thermal pad is made of silicone. In addition to adding some environmentally friendly glue, the thermal silicone pads does not need to add too many other ingredients. Therefore, it is still very environmentally friendly and safety
It is worth mentioning that the main purpose of choosing high thermal conductivity silicone gasket is to reduce the contact thermal resistance between the surface of the heat source and the contact surface of the heat sink. The high thermal silicone gasket can also fill the gap of the contact surface well and squeeze 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 addition of thermal pads, the temperature response can reach as small a temperature difference as possible, which can make the contact surfaces better and fully contact, truly Make face-to-face contact.
With the development of science and technology, thermally conductive silicone gaskets have been widely used in communication equipment, computers, switching power supplies, flat-panel TVs, mobile equipment, video equipment, network products, medical equipment, household appliances, PC servers, workstations, optical drives, COMBO, Base stations and other fields. In the future, more industry applications are waiting for thermal pads manufacturers to explore and discover.
