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

One approach to enabling liquid cooling for pluggable modules is to have the cold plate be a permanent part of the module together with liquid couplings that enable the cold plate to be coupled to or decoupled from a liquid cooling loop of the system when the pluggable module is installed or removed. However, if the liquid couplings are manual liquid couplings, the user would have to manually couple and decouple the liquid lines each time the module it is added to or removed from the system, which is not user friendly. If the liquid couplings are blind-mate liquid connectors which can automatically couple with the liquid cooling loop inside the computing device as the module is inserted into the bay, then this would solve some of the problems noted above, since the blind-mate liquid connectors do allow the module to be easily plugged and unplugged. However, blind-mate liquid connectors may suffer from other problems. For example, they pose a risk for leaking liquid into the computing system, which could damage components.
