High thermal conductivity insulating sheet

                             

The heat of machinery and equipment is not the whole heat, but the heat of some components. Therefore, the common way of heat dissipation is to install a radiator above the heat source and contact the heat source through the radiator to guide the heat from the heat source to the radiator. There is a gap between the heat source and the radiator, and the passage of heat will be obstructed, which affects heat conduction. Therefore, a thermally conductive material is required to fill the gap to eliminate the air between the gaps, reduce contact thermal resistance, and improve heat conduction.

Conventional thermal pads and thermal conductive materials can meet the need for heat dissipation. However, for equipment that requires high-power voltage such as large motors, trams, machine tools, high-precision instruments, transformers, etc., there may be voltages on both sides of the insulator. If it continues to increase, the electric charge in the insulator material will receive more electric field force, which will easily lead to ionization collisions and lead to breakdown of the insulator. Therefore, it is necessary to use a thermally conductive material that has both high thermal conductivity and high voltage resistance.

The high thermal conductivity 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 high thermal conductivity insulating sheet has strong temperature resistance and avoids aging and deterioration due to long-term overheating.
