Patent ID: 7751186

Claim:
A chassis for a computing system, comprising: a front face; a rear face; a first side and a second side, wherein each of the first side and the second side are coupled to the front face and the rear face; a first module proximate the front face, wherein the distance between the first module and the first side forms a bypass channel; a second module proximate the rear of the channel, wherein the second module (i) is permeable so as to permit the transfer of air from a direction of one of the first side and second side therethrough and (ii) prevents the transfer of air from a direction of one of the front face and the rear face therethrough; a plenum channel proximate the second module, wherein the plenum channel is formed of at least a first wall and a second wall, and wherein the first wall is permeable so as to permit the transfer of air therethrough and the second wall is solid so as to prevent the transfer of air therethrough, and wherein the first wall and the second wall are aligned substantially parallel to one another; and a fan positioned downstream of the plenum channel, wherein when the fan is activated, unheated air is drawn through the bypass channel and across the second module and wherein the activation of the fan causes negative pressure to exist in the plenum channel, causing air to flow across the second module and into the plenum channel.
