Modern transportation is very convenient. In the past, it used to take a month to travel to Beijing, but now it is possible to reach various regions of the country in one day by plane. The development of science and technology has enabled many high-tech industries that used to exist in film and television themes to be successfully applied in people's lives.
Machines and equipment are becoming larger and more functional, but their energy consumption is also increasing. It is necessary to increase sufficient power to operate them. Most electrical devices generate heat during operation, which is unavoidable because heat is generated when current passes through resistors. The greater the power consumption, the more heat is emitted, which can easily cause the internal temperature of the machine equipment to be too high, thereby affecting its performance and service life.
In order to ensure the long-term operation of machinery and equipment, heat sinks are usually installed above power consuming components to guide heat from the heat source into the heat sink, thereby dissipating heat in a timely manner and enabling the machinery and equipment to operate within a stable temperature range. There is a gap between the heat source and the radiator, and the air in the gap will hinder the transfer of heat. Therefore, it is necessary to fill the gap with a thermal conductive material to eliminate the air at the interface, so that heat can quickly pass through the thermal conductive material to the radiator.
Large machinery and equipment or some high-precision instruments require high voltage, often resulting in excessively high internal voltage. Common thermal conductive materials are extremely prone to ionization, causing them to break down and activate. Therefore, it is necessary to use thermal conductive materials that can withstand high breakdown voltage, such as heat dissipation insulation sheets.
Thermal insulation sheet is a silicone polymer elastomer reinforced with glass fiber as the substrate. This silicone cloth can effectively reduce the thermal resistance between electronic components and heat sinks, and is electrically insulated. It has high breakdown voltage strength, good thermal conductivity, tear resistance, and other characteristics, which can effectively avoid accidents such as leakage and breakdown. At the same time, the heat dissipation insulation sheet has strong temperature resistance, avoiding aging and deterioration due to prolonged overheating.
The heat dissipation insulation sheet not only has high breakdown voltage resistance, but also has an extremely thin thickness. Faced with the current trend of high integration, it can be well filled in devices with extremely high internal space utilization and can play a role in thermal conductivity.
