Abstract
The present invention attempts to reduce the thermal resistance with the use of heat-transfer devices (e.g., vapor chambers) placed directly on the heat-generating components in IT equipment and the integration of a cold plate within the cabinet. In some embodiments, the present invention is a thermal management system comprising a cabinet-side thermal management system and a server-side thermal management system using moveable thermal components.
Claims19
A thermal management system comprising:
- a cabinet including a cabinet thermal management system, said cabinet thermal management system including a cooling element;
- and
- an equipment chassis slidable into said cabinet, said equipment chassis including a server thermal management system, said server thermal management system including a heat removal system and a server thermal connector,
- wherein said server thermal connector includes a heat removal system interface connected to said heat removal system, a cabinet interface for interfacing to said cooling element, and a slidable thermal wedge disposed between said heat removal system interface and said cabinet interface, said slidable thermal wedge being slidable between a first position relative to said equipment chassis and a second position relative to said equipment chassis, said first position preventing thermal contact between said cabinet interface and said cooling element, and said second position providing thermal contact between said cabinet interface and said cooling element.

A thermal management system comprising:
- a cabinet including a cabinet thermal management system, said cabinet thermal management system including a cooling element and a cooling element vapor chamber, said cooling element vapor chamber comprising a flexible wall;
- and
- an equipment chassis slidable into said cabinet, said equipment chassis including a server thermal management system, said server thermal management system including a heat removal system and a server thermal connector, said equipment chassis having a thermal interface window,
- wherein at least a part of said flexible wall of said cooling element vapor chamber is capable of sliding into said thermal interface window of said equipment chassis to make thermal contact with said server thermal connector.
1 more element
A thermal management system comprising:
- a cabinet including a cabinet thermal management system, said cabinet thermal management system including a cooling element, said cooling element being at least one of a cold plate, a heat pipe, or a plurality of waterlines;
- and
- an equipment chassis slidable into said cabinet, said equipment chassis including a server thermal management system, said server thermal management system including a heat removal system and a server thermal connector,
- wherein said equipment chassis includes a thermal interface window,
- wherein said heat removal system includes at least one of a vapor chamber, a cold plate, or a heat sink, said heat removal system being in contact with at least one heat-generating component installed in said equipment chassis, and
- wherein said server thermal connector includes a heat removal system interface connected to said heat removal system and a slidable thermal wedge, said slidable thermal wedge being slidable against said heat removal system interface between a first position relative to said equipment chassis and a second position relative to said equipment chassis, a movement of said slidable thermal wedge into said first position retracting said server thermal connector inside of the equipment chassis and preventing thermal contact between said server thermal connector and said cooling element, and a movement of said slidable thermal wedge into said second position extending said server thermal connector out of said thermal interface window of said equipment chassis and providing thermal contact between said server thermal connector and said cooling element.
