Usage of thermally conductive sheets
High thermal conductivity sheets should be applied between the camera side(s) and the mounting and/or
heat sink(s) in order to maximize heat conductivity. Cavitar offers dedicated thermally conductive sheets
and heats sinks for passive cooling as optional accessories.
When applying thermally conductive sheets the following guidelines should be followed:
•
Use only thin (up to 0.5 mm) sheets with high thermal conductivity
o
Cavitar offers thermally conductive sheets with the following specifications:
▪
Thickness 0.2 mm
▪
Thermal conductivity 6 W/mK
•
Ensure the sheets are clean, sufficiently large (to cover the entire interface area) and unused
•
Ensure the surfaces to be joined are properly cleaned
o
Dirt in the interface can prevent proper thermal contact between the surfaces
•
Always ensure that possible protective foils are removed before use
o
Protective foils typically have very poor thermal conductivity and if they are not removed,
heat transfer from camera to heat sinks(s) will be severely compromised
•
Remember to apply thermally conductive sheets in all interfaces between the camera and the
final heat sink (e.g. welding machinery)
•
Do not re-use thermally conductive sheets
In the following figures the usage of thermally conductive sheets is shown in detail in combination with
Cavitar heat sinks designed for C300.
