Abstract
In this work, an improved multi-channel cold plate is designed based on a traditional multi-channel cold plate for enhancing its performance. Taguchi experimental design, grey relational analysis and analysis of variance are applied to investigate the effects of multi-factors on the performance of the improved multi-channel cold plate. In addition, j/f factor is employed to evaluate the overall performance of the improved multi-channel cold plate. Results suggest that j/f factor of the improved multi-channel cold plate is the highest when the mass flow rate, channel number, ambient temperature and oblique angle are 0.4 g/s, 6, 35 °C and 45°, respectively. Moreover, the impact of multi-factors on the j/f factor is ranked as: ambient temperature > channel number = oblique angle > mass flow rate > numerical error. Finally, mass flow rate, channel number and ambient temperature dominate the pressure drop, heat transfer coefficient and j/f factor of the improved multi-channel cold plate, respectively. This work provides a significant reference and valuable guidance for designing improved multi-channel cold plates.
