Abstract

Server baskets for use in immersion tanks are described herein. In one example, a server basket may be configured to receive a computer server. The server basket may include a cable management housing that has one or more data and power ports. The cable management housing may be located at or proximate to a top portion of the server basket. When the server basket is immersed in dielectric fluid in an immersion tank, the cable management housing may be located above a liquid level, thereby providing convenient access to the one or more ports. A signal repeater may be located in the cable management housing and above the liquid level. The server basket may include support arms that can be deployed when removing the server from the dielectric fluid. The support arms may enable drip drying and fluid recapture by the immersion tank. Other examples may be claimed or described.

A two-phase immersion cooling system may include an immersion tank containing dielectric fluid. When cooling an electronic device that is immersed in the dielectric fluid, vigorous boiling may occur proximate to the device, and a stream of vapor bubbles may be produced. To prevent the stream of vapor bubbles from adversely affecting cooling performance elsewhere in the immersion tank, a baffle assembly may be provided. The baffle assembly may be removably attachable to the electronic device. In one embodiment, the baffle assembly may include a plate having one or more slots. The baffle assembly may include one or more posts extending from the plate and being configured to attach to a substrate of the electronic device. The baffle assembly may include a baffle that is removably attachable to the one or more slots. Other examples may be claimed or described.

Abstract

An immersion cooling system for electronic equipment including a tank adapted to hold a liquid heat transfer fluid into which the electronic equipment can be immersed and a filter assembly(ies) having a filter housing with an inlet and an outlet and containing a filter cartridge. In some embodiments the filter assembly(ies) is adapted to be located in the heat transfer fluid in the tank, such that a cross-sectional area of the filter housing inlet is greater than a cross-sectional area of the filter housing outlet, the filter housing inlet is substantially vertically oriented on a side of the filter housing, the filter cartridge is positioned within the filter housing at an inclined angle relative to the filter housing inlet, and the filter housing outlet is disposed adjacent to a top of the housing. Advantageously, heat generated by the immersed electronic equipment produces a convective flow of heat transfer fluid through the filter housing.
