Abstract

Disclosed is a design for a universal door hinge for a datacenter rack. The Universal Rack Door Hinge uses a screw, an inner and outer brace that also integrate a hinge point, and a user-adjustable knob to initiate a clamping action that accommodates a door produced by any manufacturer while improving noise and thermal control as well as Electromagnetic Interface (EMI) containment.

Clamping Hinge for Universal IT Rack-Door Mount

Customers buy information technology (IT) equipment from a manufacturer, and then house it in datacenter racks that are made by a different manufacturer, because the racks are established and waiting to be populated. This common practice, along with installing certain combinations of rack mount systems, can generate a variety of issues for the customers. Some of these issues are:


• Some combination of systems may generate an excessive amount of noise


• Some combination of systems may generate an excessive amount of heat


• Some systems may introduce Electromagnetic Interface (EMI) issues, as generic racks often are not EMI containers


• Some rack doors contain system level status indicators. Customers lose this key function if they cannot mount the manufacturer's rack door.

These problems could be solved if the manufacturer provided a front and/or rear rack door mounting solution that could easily attach to the customer's existing rack. However, racks from different manufacturers vary greatly in the location and manner in

which the doors hinge and latch, prohibiting manufacturers/vendors from offering a universal rack door solution. From a branding perspective, due to the rack design, a manufacturer's logo might be hidden.

Many of the IT rack cabinets on the market have vertical support members at the front left/right (L/R) and rear L/R corners. These vertical supports, which typically accept the rack manufacturer's own door hinges, provide valuable real estate for a universal hinge.

The novel contribution is a design for a universal door hinge that uses a screw, an inner and outer brace that also integrate a hinge point, and a user-adjustable knob to initiate a clamping action. A top hinge and bottom hinge are secured by the user by

rotating the large knob, thus tightening the braces. The knob is located against the inner brace, for security reasons, not easily allowing external access. The screw is attached to the outer brace so that when tightened it protrudes into the cabinet space and does not interfere with neighboring rack cabinets or compromise floor spacing/layout. One additional clamping hinge can be modified and used on the opposite vertical cabinet support to provide a latch catch for a door handle and/or lock.

The Universal Rack Door Hinge has many advantages. It enables the IT equipment manufacturer to offer an acoustic door solution to customers who purchase a loud rack mount product, but do not use manufacturer-specific racks. The universal hinge allows rack doors to have thermal advantages, such as a manufacturer-agnostic rear door heat exchanger as well as the ability to install a higher-percent open rack door than what is already in place to meet thermal demands. The Universal Rack Door Hinge enables development of front/rear rack doors that...
