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

Once the module 700 is fully received in the bay 600 (see FIG. 6A), the actuator 660 will actuate the engagement mechanism 650 by rotating the shaft 665. This causes, through interaction between the threads on the shaft 665 and the threads in the linkage 667, the linkage 667 to move towards the engaged position (movement “a” in FIG. 6A). This causes the second link 653 to move towards its engaged position (movement “b” in FIG. 6A), which applies a force to the engagement bar 626 that moves it downward in an arc (movement “c” in FIG. 6A). This results in the state shown in FIG. 6B in which the cold plate 630 is in the engaged position and is in contact with the module 700.

Although the examples illustrated in FIGS. 1-6 show the electronic actuator 660 being used in a cold plate assembly 610 having just one bay 600, it should be understood that the electronic actuator 660 could also be used in cold plate assembly 610 having multiple bays.
