Thermal Management, Heatspreader And Cooling Solutions - Kontron COMe-bID7 User Manual

9.2. Thermal Management, Heatspreader and Cooling Solutions

A heatspreader plate assembly is available from Kontron for the COMe-bID7. The heatspreader plate on top of this
assembly is NOT a heat sink. It works as a COM Express®-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 worst
case 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
85°C for industrial temperature grade modules (E2/XT)
You can use many thermal-management solutions with the heatspreader plates, including active and passive
approaches.
The optimum cooling solution varies, depending on the COM Express® application and environmental conditions.
Active or passive cooling solutions provided from Kontron for the COMe-bID7 are usually designed to cover the power
and thermal dissipation for a commercial grade temperature range used in a housing with proper air flow.
HOT Surface!
Do NOT touch! Allow to cool before servicing.
