摘要
An example computing device includes one or more bays to receive a pluggable module, and a cold plate assembly. The cold plate assembly includes one or more cold plates to engage with the pluggable modules and transfer heat from the modules to liquid coolant. The cold plate assembly also includes a pivoting support that supports the cold plate(s) and pivots relative to the system board, and an engagement mechanism comprising a mechanical linkage with mechanical advantage attached to the pivoting support such that moving a link of the mechanical linkage causes the pivoting support to pivot between an engaged position and a disengaged position. In the engaged position, the cold plate contacts is positioned to engaged with the pluggable module, while in the disengaged position the cold plate is disengaged from the pluggable module.

For example, when engaging the cold plate 630, the pivoting support 621 may be driven a small distance past a point at which the cold plate 630 first makes contact with the thermal interface 723 of the module 700. The spring 640 absorbs this additional movement so that the pluggable module 700 is not damaged thereby. In addition, the radial spring 640 applies a restoring spring force downward against the cold plate 630, which maintains a modest contact pressure between the cold plate 630 and the thermal interface 723, thereby improving the rate of heat transfer therebetween.
