Abstract
An assembly comprising an integrated cooling system/liquid containment system/EMI shield/pump housing/heat sink is built atop a multi-chip module. The attached devices are cooled by a spray of fluid, effecting a phase change from liquid to gas at the point of evaporation. Condensing liquid accumulates at the base of the fins and is collected by a pump for redistribution. The pump is coupled to a fan blade, which in turn is operated by a motor. A seal is formed between the multi-chip module and the integrated housing. The assembly is designed such that this seal need not be broken to service the motor, thus minimizing the amount of vapors from the working fluid lost into the atmosphere. Case fins and fan blades are arranged for improved efficiency.
