Depending on the connection location on the heat load unit, the XDU™ Liquid to Air Heat Exchanger for Chip Cooling offers
top and bottom supply and return connections. See Figure 6.1 below.
Figure 6.2 on the facing page, shows the general arrangement of the isolation valves and trap of the cooling fluid circuit on
a bottom-connected system. A top-connected XDU™ Cooling System would use item 6 as a high point vent for the removal
of air from the system.
