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.

Thus, the pivoting support 621 can be caused to move between the engaged position and the disengaged position by moving the second link 653 of the mechanical linkage 651 between its engaged and disengaged positions. Accordingly, actuating the engagement mechanism 650 means moving the second link 653 of the mechanical linkage 651, actuating the engagement mechanism 650 to engage the cold plate 630 means moving the second link 653 into its engaged position, and actuating the engagement mechanism 650 to disengage the cold plate 630 means moving the second link 653 into its disengaged position.

Although one mechanical linkage 651 is described above for simplicity, there may be more than one. For example, in FIGS. 1 and 9, there are two mechanical linkages (one on either side of the pivoting support 621).

There are a variety of ways that the engagement mechanism 650 can be actuated. For example, the engagement mechanism 650 may be automatically actuated by an electronic actuator, or it may be manually actuated by a user. Some specific examples of different approaches to actuating the engagement mechanism 150 are described in greater detail below in sections 1.3 and 1.4.

1.3. Engagement Mechanism with Electronic Actuator

In one example, an electronic actuator 660 may be coupled to the mechanical linkage 651 to cause the second link 653 to move between the engaged and disengaged positions (See FIGS. 1-6B). The electronic actuator 660 may be any electronic device that is capable of generating linear movement of the second link 653.
