This article describes a means for removing heat from an array of modules 2 having very large scale integrated (VLSI) circuits 4 mounted thereon with solder ball connections 6. The array of modules 2 are mounted on a board 8, and has a module cap 10 connected to a first rigid duct wall 12 via a machined plate 14. The first rigid duct wall 12 is connected to a second rigid wall 16 by a plurality of stiffeners 18 and springs 20. A coolant 22 flows between the rigid walls 12 and 16 to extract the heat.
