## Processor cooling using phase change materials

### Przemysław Andrzej Krukowski

#### Abstract

In the following paper a numerical model is used to analyse a processor cooling radiator with phase change material (PCM) container. The goal is to maintain effective cooling in conditions of simulated fan failure. First of all, in order to provide an insight into the topic of PCM based electronics cooling the way such systems operate is introduced. Various applications of PCM in different areas are discussed with special attention to PCM procesor cooling. Various concepts of systems and materials used in these systems are presented. Next, development of numerical model in Ansys Fluent is described. It was based on a real radiator, which was experimentally tested. Following stages of model creation are: adoption of simplifications for physical model, geometry implementation, spatial discretization – mesh creation, selection of appropriate boundary and initial conditions. Model underwent tests. Results were compared with empirical data. Numerical model was found useful in further analysis. Using developed model a parametrical analysis was performed. The point was to find how modification of chosen geometric dimensions affects effective work of radiator in conditions of simulated fan failure. For one of tested dimensions there was found an interval inside of which there is optimal value. Methodology of analysis presented in this paper might be used to analyse and to a certain extent to optimize processor cooling systems using phase change materials
