US Patent 7016194 Method and apparatus for cooling a module portion

A method of cooling a module portion (202) of an embedded computer chassis (200), where the module portion comprises a front module (206) coupled to a front portion of a backplane (204), and a rear module (208) coupled to a rear portion of the backplane, where the front module and the rear module are horizontally disposed, the method includes drawing a cooling air mass (240) into the embedded computer chassis through a front surface (230) of a first interspace region (220) and an upper front surface (231) of a second interspace region (221) in a direction substantially perpendicular (250) to the front surface and the upper front surface. A third interspace region (222) receives a first portion of the cooling air mass (241), the cooling air mass exhausting from the embedded computer chassis through a rear surface (210) in a direction substantially perpendicular (256) to the rear surface.
