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.

As another example, the signal may be generated by the electronic module 700 responsive to receiving power from the system board, and may be communicated to the actuator 660 via a pin of the connector 602 and a conductive path connected thereto, such as a wire or signal trace on the system board 2.

In some examples, the electronic actuator 660 may automatically move the second link 653 to the engaged position in response to user input. For example, a user may push a button on the module 700 or on the computing device 1 that causes an engagement command to be generated that controls the actuator 660 to actuate the engagement mechanism 650 to engage the cold plate 630.

In some examples, the electronic actuator 660 may automatically move the second link 653 to the disengaged position in response to user input. For example, a user may push an eject button 750 on the module 700 or on the computing device 1 that causes an eject command to be generated that controls the actuator 660 to actuate the engagement mechanism 650 to disengage the cold plate 630.

Although only one actuator 660 is discussed above for simplicity, there may be more than one actuator 660 in the same cold plate assembly 610. For example, there may be one actuator 660 for each of the mechanical linkages 651. For example, two actuators 660 are illustrated in the example computing device 1 shown in FIGS. 1 and 2. In examples in which there are multiple actuators 660, they may be actuated in unison.
