Abstract:
1. An electronics assembly, comprising: a first finned structure having a first support plate and a plurality of substantially vertical first fins extending from a surface of the first support plate; a first electronics module mounted to an opposite surface of the first support plate; a second finned structure having a second support plate and a plurality of substantially vertical second fins extending from a surface of the second support plate, wherein the second finned structure aligned in series in a passive convective air flow direction above the first finned structure and wherein the first support plate is coupled with the second support plate; a second electronics module mounted to an opposite surface of the second support plate; and a horizontal baffle placed in a gap between the first finned structure and the second finned structure, wherein the horizontal baffle is positioned relative to the first and second finned structures to block convective air from entering the second finned structure after the convective air flows through the first finned structure.
