Effect of patterned surfaces on thermal impedance reduction

Abstract

COMSOL was used to simulate how these structures will enhance the heat transfer from the heat source and predict heat transfer enhancement. Proof of concept experiment was performed using patterned surfaces and Polydimethylsiloxane (PDMS). It was shown that effective thermal conductivity of PDMS can be enhanced by at least 6-fold and ITR can be reduced by 10 times using surface patterning.
