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.

說明書

The pivoting support 621 rotates between an engaged position and a disengaged position. When in the engaged position, the cold plate 630 is in contact with a thermal interface 723 in the pluggable module 700 (assuming one is installed in the bay 600), and when in the disengaged position the cold plate 630 is not in contact with the thermal interface. More precisely, when the pivoting support is in the engaged position, then the cold plate 630 is located such that it would be in contact with a thermal interface 723 of the pluggable module 700 if the module 700 were installed in the bay 600. Similarly, when the pivoting support is in the disengaged position, then the cold plate 630 is located such that it would not be in contact with a thermal interface 723 of the pluggable module 700 if the module 700 were installed in the bay 600. The disengaged position may also provide sufficient clearance between the cold plate 630 and the pluggable module 700 that the cold plate 630 does not interfere with the pluggable module 700 being inserted or removed. The thermal interface 723 may be disposed on the top surface of a device to be cooled.
