A multi-channel cold plate for cooling chip wherein a first set of cooling channels function as main cooling channels and a second set of cooling channels function as a secondary and/or backup cooling channels. The two sets of cooling channels are fluidly isolated from each other, such that cooling fluid from one sent of channels cannot flow or intermix with the cooling fluid of the other cooling channel. The secondary cooling channels can be operated when demand for heat removal is increased or when the main cooling channels is unable to manage the thermal condition of the chip properly.

A two-phase immersion cooling system for cooling electronics. The electronics are immersed in immersion tank filled with phase change liquid. As liquid evaporates due to heat generated by the electronics, it enters a vapor passageway that leads the vapor to a condenser situated remotely from the immersion tank. Upon condensing at the condenser, the condensed liquid is directed to a resupply tank, wherein the condensed liquid cools. When the level of the two phase liquid in the immersion tank drops below a set threshold, a pump is activated to deliver the condensed liquid from the resupply tank to the immersion tank. The immersion tank, vapor passageway and condenser are position inside a containment passageway. The containment passageway captures any vapor not entering the vapor passageway and direct such vapor to the condenser. An air mover generates pressure differential within the containment passageway to direct the vapor towards the condenser.

A two phase coolant immersion system includes a top section and an immersion section, where the top section and the immersion section are separated by one or more panels. The immersion section includes at least a number of server slots to receive a number of servers, where each of the servers is at least partially submerged within two phase liquid coolant within the immersion section, where, when the servers operate, the servers generate heat that is transferred to the two phase liquid coolant causing some of the two phase liquid coolant to turn into a vapor. The two phase coolant immersion system includes a condensing section interfaced with the immersion section, where the condensing section includes a vapor collection compartment to collect two phase liquid coolant in vapor phase and a liquid collection compartment situated beneath the vapor collection compartment. The one or more panels prevent vapor loss to the environment.

Devices, systems, and methods are disclosed for cooling using both air and/or liquid cooling sub circuits. A vapor compression cooling system having both an air and liquid cooling sub circuit designed to service high sensible process heat loads that cannot be solely cooled by either liquid or air is provided.

The present invention discloses a three-chambered constant pressure apparatus for liquid immersion cooling of servers. The apparatus comprises a housing within which two partitions are disposed. The two partitions divide the housing into a first chamber, a second chamber and a third chamber. A coolant is maintained within the first chamber, and an isolating liquid is maintained within the second chamber and the third chamber. At least one heat-generating device is submerged within the coolant maintained within the first chamber. During the operation of a server, a coolant is heated to a boiling point temperature generating a coolant vapor that causes the pressure in chambers to rise. By adjusting the air pressure in chambers prior to use, the rising pressure in chambers caused by the coolant vapor can be efficiently relieved. Therefore, the immersion cooling apparatus is maintained at a constant pressure during operation, ensuring the reliability of the immersion cooling apparatus and the sustainability of cooling capacity.
