Abstract
Miniaturization technologies have led to a dramatic increase in electronics cooling requirements, which traditional cooling approaches are unable to fulfill. Thus, it is necessary to identify working fluids that enhance cooling performance and meet environmental and safety requirements. In this work, we develop a computer-aided molecular design approach to identify working fluids that have better heat transfer performance than the industrial refrigerant HFE 7200. We use group contribution methods as the major property estimation tool along with additional accurate property models. We derive a metric to measure the cooling performance of a two-phase cooling system consisting of microchannel heat sinks. Utilizing metrics for biodegradability and lethal concentration (LC50) enables additional analysis of the candidate molecules. Finally, we provide predictions of chemical stability to minimize the risk of potential chemical transformation. As a result of this work, we identify a number of novel cooling fluid...
