Abstract

The present disclosure describes swivel hinge assemblies for use in rotatably mounting two structures together, such that the structures are in fluid communication by way of fluid flow, as well as systems including such hinge assemblies. The swivel hinge assemblies generally comprise a fluid inlet port, a fluid outlet port, shafts surrounding the inlet and outlet ports and allowing for rotation about one or more axes, and attachment means which may be integrally formed with the shafts of the hinge assembly. In use, these assemblies eliminate the use for secondary hinges or secondary mounting hardware in attaching a door and a structure together in order to maintain fluid communication between an electronics rack and a heat exchanger mounted on the door of an electronics rack.

Dependent claims

A swivel hinge assembly comprising:

a first relatively stationary base member and a second relatively stationary base member;
a first swivel member that is integral with the first relatively stationary base member;
a second swivel member that is integral with the second relatively stationary base member;
a channel extending through both the first swivel member and the second swivel member and providing fluid communication between the first and second swivel members;
wherein the first base member and the first swivel member include a swivel shaft and the second base member and the second swivel member include at least one aperture in which the swivel shaft is journaled for rotation;
wherein the first swivel member and the second swivel member are rotatable about a longitudinal axis passing through the swivel shaft;
and
wherein at least one of the first and second swivel members is at least partially within an associated base member.
