2.18. Q7-AL Heatspreaders
The Q7-AL is designed to operate at its maximum CPU speed and requires a thermal solution to cool the CPU.
ADLINK offers two passive heatsinks, one active heatsink, and two heat spreaders for cooling. Each Q7-AL module
requires one of the three heatsinks (either the Q7-AL-HS3, Q7-AL-HS4, or the Q7-AL-HS5) or one of two heat
spreaders (either the Q7-AL-HS1 or the Q7-AL-HS2) depending on the featured CPU (HS1 for E-series or HS2 for
N-series). The heat spreaders must be combined with additional forms of cooling such as active heatsinks. The
Q7-AL-HS3 active heatsink must be combined with one of the two heat spreaders (Q7-AL-HS1 or Q7-AL-HS2).
2.18.1. The Q7-AL-HS1 heat spreader must be used for the Q7-AL-E3950/40/30 modules. As can be
seen in Figure-1, the Intel Atom E39xx SoCs come with mounted Intel heat spreaders, which
look like metallic lids and add 2mm to the heights of the SoCs. The Q7-AL-HS1 heat spreader
is designed for the extra heights of these SoCs. See the following diagram for a mechanical
overview of the Q7-AL-HS1 heat spreader.
