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 mechanical linkage 651 may be described as having mechanical advantage, meaning that a mechanical advantage of the linkage 651 is greater than 1. The mechanical advantage of the linkage is equal to F1/F2, where F1 is the force applied by the first link 652 to the engagement bar 626 in response to the horizontal force F2 being applied to the second link 653. This is substantially equivalent to the value D2/D1, where D1 is the distance that the engagement bar 626 moves in response to a horizontal movement of distance D2 by the second link 653. For example, in the context of FIG. 5A, the mechanical advantage of the mechanical linkage 651 may equal (d2?d3)/(d1+ε), where ε is a distance that the pivoting support 622 continues to move after initial contact between the cold plate 630 and the thermal interface 723. In some examples, the mechanical linkage 651 may be configured to have mechanical advantage greater than or equal to four.

The position of the second link 653 when the pivoting support 621 is in the engaged position may be called the engaged position of the second link 653. Similarly, the position of the second link 653 when the pivoting support 621 is in the disengaged position may be called the disengaged position of the second link 653.
