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 cold plate engagement mechanism 650 includes at least one mechanical linkage 651 and associated link guide 654 (see FIGS. 1-4C and 9-11B). The mechanical linkage 651 includes a number of links, including a first link 652 and a second link 653. One end of the first link 652 is pivotally connected to the engagement bar 626 of the pivoting support 621, and the other end is pivotally connected to the second link 653. The second link 653 is held by the link guide 654, which constrains the movement of the second link 653 to one dimension (e.g., horizontal movement in the illustrated examples).

The mechanical linkage 651 is configured such that, when a force is applied to the second link 653 along a first direction aligned with its constrained dimension, this is translated into a force applied to the engagement bar 626 that biases the pivoting support 621 towards rotating downward. In other words, when the second link 653 is moved in the first direction, this causes the pivoting support 621 to rotate downward. Conversely, when a force is applied to the second link 653 along a second direction opposite to the first direction, this is translated into a force applied to the engagement bar 626 that biases the pivoting support 621 towards rotating upward. In other words, when the second link 653 is moved in the second direction, this causes the pivoting support 621 to rotate upward.
