US 9,049,800 B2 · Immersion server, immersion server drawer, and rack-mountable immersion server drawer-based cabinet

Abstract

An information handling system includes: an immersion server drawer (ISD) having: an impervious enclosure which holds a volume of dielectric cooling liquid within/at the enclosure bottom. The ISD is configured with dimensions that enable insertion of liquid-cooled servers within the enclosure bottom. A plurality of liquid-cooled servers can be placed in a side-by-side configuration along one dimension of the ISD, with one or more heat dissipating components of the servers being placed below a surface layer of the cooling liquid. Submerged components of the immersion server are liquid-cooled, while the other heat generating components above the liquid surface are air cooled by rising vapor generated by boiling and vaporization of the cooling liquid. The ISD is placed in an ISD cabinet, which is configured with an upper condenser that allows for multi-phase cooling of the electronic devices placed within the immersion server drawer. The ISD cabinet can be rack-mountable.

Dependent claims

An information handling system comprising:

an immersion server drawer having:
an impervious enclosure configured with opposing side walls, opposing front and rear walls and a bottom wall;
wherein the immersion server drawer has (1) a depth dimension extending from the front wall to the rear wall that is sized to receive one or more servers in one of a first orientation and a second orientation, (2) a width dimension extending from a first side wall to a second side wall that is sized to receive one or more servers in one of a first orientation and a second orientation, and (3) a height dimension extending from the bottom wall to a top of the opposing side walls and sized to receive at least a single server;
and
wherein the immersion server drawer is configured to hold a volume of immersion cooling liquid within a bottom section of the enclosure at which the one or more servers are placed to be liquid cooled.

2 more elements

An immersion server drawer cabinet assembly comprising:

an immersion server drawer cabinet having:
at least one drawer receptacle configured to accommodate insertion of an immersion server drawer;
and
a condenser located within an upper section of the enclosure, vertically above the top of an inserted immersion server drawer, and which condenses rising vapor that evaporates off the surface of the dielectric fluid held within the immersion server drawer as the one or more servers located within the immersion server drawer dissipates heat into the dielectric fluid.
