Thermal gels are used for thermal management primarily because of their ability to efficiently conduct heat away from electronic components or other devices. Here are some reasons why thermal gels are used for this purpose:
-
High Thermal Conductivity: Thermal gels are formulated with materials that have high thermal conductivity, such as silicone or certain polymers. This allows them to efficiently transfer heat away from heat-generating components to heat sinks or other cooling mechanisms
-
Conformability: Thermal gels are often soft and conformable, allowing them to fill gaps and irregularities between surfaces, such as between a semiconductor device and a heat sink. This ensures optimal contact and thermal transfer, even in areas with uneven surfaces
-
Reduced Thermal Resistance: By filling gaps and voids, thermal gels minimize thermal resistance between the heat source and the cooling mechanism, leading to more effective heat dissipation
-
Electrical Isolation: Many thermal gels provide electrical insulation properties, which are essential for electronic devices where electrical conductivity between components could cause short circuits or other issues
-
Shock Absorption: Some thermal gels also offer shock absorption properties, which can help protect delicate electronic components from mechanical stress or vibration
-
Ease of Application: Thermal gels are available in easy-to-apply formulations, such as pre-cut pads or syringe dispensable compounds, making them convenient for manufacturing and assembly processes
Some key features and benefits include:
- One-component, dispensable
- Eliminates multiple part numbers
- Aids in automation
- Fully cured
- Requires no refrigeration
- No mixing or additional curing
- No settling in storage
- Long-term reliability
- Will not harden
- Will not become brittle or crack
- Highly conformable at low pressure
- Applies minimal stress, making it effective for delicate components
- High surface tack
- Easily reworkable
- Designed for a wide range of gaps
