Heat Spreader and Cooling Solutions
A heatspreader plate assembly is available from Kontron for the Qseven-Q7AL. The heatspreader plate on top of this
assembly is NOT a heat sink. It works as a QSEVEN-standard thermal interface to use with a heat sink or external
cooling devices.
External cooling must be provided to maintain the heatspreader plate at proper operating temperatures. Under
worstcase conditions, the cooling mechanism must maintain an ambient air and heatspreader plate temperature on
any spot of the heatspreader's surface according the module specifications:
60°C for commercial grade modules
75°C for extended temperature grade modules (E1)
85°C for industrial temperature grade modules (E2/XT)
The aluminum slugs and thermal pads or the heat-pipe on the underside of the heatspreader assembly implement
thermal interfaces between the heatspreader plate and the major heat-generating components. About 80 % of the
power dissipated within the module is conducted to the heatspreader plate and can be removed by the cooling
solution. For documentation and CAD drawings of heatspreader and cooling solutions refer to:
