5.2 Cooling Solution COMe-cP2020i
The thermal concept of the COMe-cP2020i is based on a specially designed full-board heat sink with fins which contacts the
main hot spots of the board and therefore provides optimal heat transfer from the board's top surface.
The heat sink with fins is designed for operating the board up to 85°C ambient temperature. This heat sink needs external
air flow of about 4mps to reach the maximum cooling performance.
To determine cooling performance, the module temperature can be measured at the temperature reference point indicated
in the figure below.
The air flow must in any event maintain a heatspreader plate temperature of 92°C or less.
