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(shuō)明書

In some examples, the pivoting support 621 also includes locking pins 627, which extend downward from the engagement bar 626 (see FIG. 1). The locking pins 627 lock the pluggable module 700 in place in the bay 600 when the cold plate 630 is engaged with the pluggable module 700 (see FIG. 4C), and release the pluggable module when the cold plate 630 is disengaged from the pluggable module 700 (see FIG. 4B). As the cold plate 630 moves downward the locking pins 627 may also move downward until they engage latching features of the pluggable module 700, such as the notch 712, such that the locking pins 627 prevent the pluggable module 700 from being removed. Conversely, as the cold plate 630 moves upward, the locking pins 627 also move upward until they disengaged from the latching features of the pluggable module 700, thereby releasing the module 700.

1.2.2. Cold Plate(s)

The cold plate(s) 630 may each include a main body 631 that is to thermally couple with the pluggable module 700, a liquid conduit 633 that conducts heat from the main body 631 into liquid coolant, liquid lines 634 that supply and return the liquid coolant to and from liquid conduit 633, couplings 635 that mechanically couple liquid lines 634 and liquid conduits 633, and an axial support 636 that connects the cold plate to the support arms 622 (via radial springs 640) (see FIG. 1).
