PARAMETRIC ANALYSIS OF THE THERMAL SHIELDING PERFORMANCE OF A COLD PLATE WITH A SERPENTINE FLOW DESIGN
Abstract
Cold plate is an effective way to shield a high temperature object to ensure personal safety. In this research, both
horizontal and vertical cold plates with a serpentine flow design were investigated through experiment and
simulation. Simulation models of both cold plates were constructed and verified with experimental results, and
the influences of structural and operating parameters of cold plates on the thermal shielding performance were
discussed, including the number of flow passes, the thickness of channel, the inlet volumetric flow rate and the
thickness of thermal insulation material attached to the hot surface of the cold plate. The results indicate that as
the number of flow passes increases, the temperature uniformity of the cold surface can be improved, but its
average temperature will increase. It was found that when the channel thickness is 3 mm, there is a local
maximum value for the average temperature and the maximum temperature difference of cold surface where the
thermal shielding performance is poor. In addition, increasing the inlet volumetric flow rate and the thickness of
thermal insulation material can significantly improve the thermal shielding performance of a cold plate.
