Abstract

A method of providing an electronic equipment enclosure having a plurality of panels, including identifying at least one panel through which air is intended to flow, determining the design parameters of the identified panel, and providing an electronic equipment enclosure that includes the identified panel, constructed according to the determined design parameters. Determining the design parameters of the identified panel includes first establishing a maximum ratio of open area to closed area of between 60% and 70% and then determining one or more other parameters of the design of the identified panel in view of the established maximum ratio of open area to closed area. Other parameters include the material of which the identified panel is to be constructed, its thickness, and its rigidity. Specific enclosures benefiting from the design process are also described.

Dependent claims

A method of providing an electronic equipment enclosure having a plurality of panels, at least one panel of which indented to facilitate maximum ventilation airflow through the electronic equipment enclosure, the method comprising:

(a) determining design parameters of a panel for the electronic equipment enclosure through which air is intended to flow for ventilating the electronic equipment enclosure, including:
(i) establishing a ratio of open area to closed area in the panel of between 60% and 70% in order to facilitate maximum ventilation airflow for the electronic equipment enclosure,
(ii) determining the parameters of openings in the panel such that the established ratio of open area to closed area is preserved, and
(iii) determining other parameters of the design of the panel while preserving,
(A) the established ratio of open area to closed area in the panel, and
(B) the determined parameters of the openings in the panel;
(b) constructing the panel according to the determined design parameter;
and
(c) providing an electronic equipment enclosure that includes the panel, constructed according to the determined design parameters, whereby maximum ventilation airflow through the electronic equipment enclosure is facilitated;
(d) wherein said step (a)(iii) comprises varying at least one of the other parameters when at least another of the other parameters is changed in order to maintain the established maximum ratio of open area to closed area.
