Highly insulating thermally conductive insulating sheet

The heat dissipation problem of machinery and equipment is the key point that affects its normal operation. It is well known that heat will be emitted during the operation of machinery and equipment, mainly because heat is generated when current passes through resistance, and heat is generally conducted through air to the outside, but air is heat Poor conduction will lead to low heat conduction efficiency. If the design of machinery and equipment is not perfect, it is easy to trap heat inside, causing the machinery and equipment to overheat and crash.
The heat of machinery and equipment needs to be dissipated in time. The conventional heat dissipation method is natural heat dissipation. In order to improve the heat transfer efficiency, the gap between the heat source and the radiator is generally filled with heat conductive material to eliminate the air in the gap and make the heat source It is in close contact with the heat dissipation device to improve the heat conduction efficiency, thereby enhancing the heat dissipation effect.


With the development of science and technology, people use more and more electrical equipment, and consume more and more electricity. Conventional heat-conducting materials are generally insulated, but in the face of high-voltage environments, they are easy to The voltage on both sides of the insulator continues to increase, and the electric charge in the insulator material is subject to the greater the electric field force, which can easily lead to ionization collisions and cause the insulator to be broken down. In order to avoid this, a highly insulating heat conduction is required. material.
Thermally conductive insulating sheet is a silicone polymer elastomer reinforced with glass fiber as the base material. This kind of insulating sheet can effectively reduce the thermal resistance between the electronic component and the radiator, and is electrically insulated, with high breakdown voltage strength, good thermal conductivity, tear resistance, etc., and can effectively avoid leakage , Breakdown and other accidents. At the same time, the heat-conducting insulating sheet has strong temperature resistance to avoid aging and deterioration due to long-term overheating.

Thermally conductive insulating sheet can work normally in a high-voltage environment, and its thickness is very thin, about 0.25-0.50mm, and the insulation strength of thermally conductive silicone cloth is much greater than other thermally conductive gaskets, so thermally conductive silicone cloth can be widely used in Solve the heat dissipation problem under high voltage environment.
