Thermal Regulation of LED Chip Using PEG/CF Composite: A Hands-On Experiment For Undergraduates

Abstract

Miao Wang, Wei Chen and Xiang Peng

A comprehensive laboratory experiment comprising the preparation of polyethylene glycol/copper foam (PEG/CF) composite, phase change properties test and thermal regulation evaluation of LED chip was designed for the undergraduate students. In this experiment, students can not only master material preparation, DSC testing, device assembling and performance evaluation, but also gain the capability of literature searching, data analysis and result discussion, thus to uncover the relationship between phase change properties and temperature regulation performance. From the perspective of higher education, this experiment could facilitate undergraduates to have a basic understanding of scientific research, strengthen their professional knowledge as well as cultivate their capability to consult literature, design experiment, analyze data and solve problems. Moreover, the experiment can arouse students to realize the importance of electronic device’s temperature control and the crucial role of PCM composite in thermal regulation.
