The objective of this paper is to numerically simulate a bellows-type RMDHL to predict its operational performance under different working conditions as well as a conventional dynamic pump-driven heat loop (DPDHL) as a benchmark for comparison. The numerical results are also compared with relevant experimental data with good agreement. The results indicate that the bellows-type RMDHL can meaningfully reduce the peak temperature of an electronic device and result in a significantly more uniform temperature across the electronic device. Considering the advantage of coolant leakage free for electronics-related applications, the single-phase bellows-type RMDHL could be an alternative to a conventional Liquid Cooling System (LCS) for electronic cooling applications.
