The Use of Phase Change materials for Elecfronic Cooling Applications: Thermal Design lssues and Example

摘要

Phase Change Materials (PCMs) are being considered for electronic cooling applications throughout academia and industry. Design issues for the use of PCMs are discussed for the example of a finned PCM heat exchanger. Issues of importance are thermal design load, PCM selection, thermal modeling of PCM systems, and the econmics of each system. Options for modeling PCM systems are presented and discussed. These options include detailed computational fluid dynamic models or simplified circuit analogy models. A simplified ciruit analogy model is developed and compared to CFD results and found to be in good agreement for identical operating conditions.
