Electrolube Thermal Management Guide
Non-silicone pastes Benefits of Thermally Conductive Products |
Thermal Management application chartMost components have a maximum effective operating temperature and failure to maintain the temperature below this can lead to two main problems:
- Increased failure rates
- Variation of electrical properties
Heat generated within components is usually removed by the use of metals, which may be formed to give high surface areas (heatsinks) or be part of the assembly's outer body. The hot component is usually mechanically attached to the metal. The limitation of this is that there will always be an air gap between the surfaces. Air is an extremely poor conductor of heat, so this air gap greatly reduces the rate of heat dissipation. The application of a flexible thermally conductive material completely fills the gap, excluding air. Electrolube products have excellent heat transfer properties ensuring that heat flows from the component into the metal heatsink at the fastest rate possible.

Typical application
The range of applications where the use of a thermally conductive material is necessary has greatly increased as electronic circuits have become more complex and powerful. These advances have resulted in greater heat generation. This heat must be drawn away from the components quickly and efficiently to ensure long term reliability and operating efficiency.
In solar panel systems it is vital that the heat is transferred with minimal loss. Electrolube's ultra-high thermally conductive pastes (over 2.8W/mK) are ideal for this application.
Thermal management in high power industrial applications e.g. traction, is particularly important.
