Abstract:
An electronic apparatus comprising:a rack configured to contain an adjacent set of electronic devices, wherein each member of said adjacent set includes a heat generating component encased in a chassis having a cover and a plurality of fins arranged on a chassis fin-mount surface opposite a chassis component-mount surface and extending from a chassis upstream air intake to a chassis downstream air exhaust, a plurality of fins and a cover of a first member of said adjacent set is arranged to face a plurality of fins and a cover of another member of said adjacent set and separated by a predetermined distance, and said rack contains a plurality of wind paths including a between-the-fins wind path and an equipment-to-adjacent-equipment bypass wind path; a fan configured to supply air into the rack so as to create air flows through said plurality of wind paths; and at least one pressure-loss adjusting member mounted on a downstream side of at least one predetermined wind path and configured such that a downstream-side cross sectional area of said at least one predetermined wind path is smaller than an upstream-side cross sectional area of said at least one predetermined wind path so as to increase a pressure loss across said at least one predetermined wind path.
