A liquid submersion cooling system that is suitable for cooling a number of electronic devices in parallel using a plurality of cases connected to a rack system. The system cools heat-generating components in server computers and other devices that use electronic, heat-generating components and are connected in parallel systems. The system includes a housing having an interior space, a dielectric cooling liquid in the interior space, a heat-generating electronic component disposed within the space and submerged in the dielectric cooling liquid. The rack system contains a manifold system to engage and allow liquid transfer for multiple cases and IO connectors to engage electrically with multiple cases/electronic devices. The rack system can be connected to a pump system for pumping the liquid into and out of the rack, to and from external heat exchangers, heat pumps, or other thermal dissipation/recovery devices.

A fluid composition or nanofluid is described that includes a dielectric base fluid, a chemical dispersant, and nanoparticles dispersed in the dielectric fluid. The chemical dispersant is used to facilitate the nanoparticle dispersing process and also to increase the stability of the nanofluid thus produced. The nanofluid is compatible with electronics and has enhanced thermal conductivity for use in cooling electronics. Techniques are described that can be used to efficiently disperse different forms of nanoparticles into a base fluid and produce a stable nanofluid which is compatible with electronic circuitry and components.

Dielectric liquid is used to cool heat generating electronic components disposed on a circuit board within a case. The liquid is poured or otherwise directed over the electronic components, with gravity assisting the liquid in flowing downward over the components, with the liquid thereafter being collected in a sump for eventual return back to the electronic components. One exemplary application of the described concepts is in cooling electronic components in computers, for example personal computers or server computers.

Gravity assisted directed liquid cooling

A liquid submersion cooled computer that includes a seamless, extruded main body used to form a liquid-tight case holding a cooling liquid that submerges components of the computer. By forming the main body as a seamless extrusion, the number of possible leakage paths from the resulting liquid-tight case is reduced. No seams are provided on the main body, and there are no openings through the walls of the main body, so liquid cannot leakage through the main body. Any leakage paths are limited to joints between the main body and end walls which are sealingly attached to the main body to form the liquid-tight case.

Extruded server case

A liquid submersion-cooled computer that is configured to reduce physical structures passing through walls of the computer liquid-tight computer case, which eliminates the amount of sealing needed around those physical structures and reduces the number of possible fluid leakage paths from the interior of the computer that contains a cooling liquid submerging at least some of the computer components. The computer includes a mechanism to pass input/output signals into and from the computer without any physical structure extending through any of the plurality of walls. The computer also has a mechanism for wirelessly transferring power into the interior space of the computer case, and a switch that controls power in the computer without having any physical structure extending through any of the plurality of walls.

Server case with optical input/output and/or wireless power supply

A portable, self-contained liquid submersion cooling system that is suitable for cooling a number of electronic devices, including cooling heat-generating components in computer systems and other systems that use electronic, heat-generating components. The electronic device includes a housing having an interior space, a dielectric cooling liquid in the interior space, a heat-generating electronic component disposed within the space and submerged in the dielectric cooling liquid, and a pump for pumping the liquid into and out of the space, to and from a heat exchanger that is fixed to the housing outside the interior space. The heat exchanger includes a cooling liquid inlet, a cooling liquid outlet, and a flow path for cooling liquid therethrough from the cooling liquid inlet to the cooling liquid outlet. An air-moving device such as a fan can be used to blow air across the heat exchanger to increase heat transfer.
