Abstract

This article conducts experimental analysis using the window program VCTM V1.0 to investigate the thermal performance of a vapor chamber and then applies the findings to a high-performance server. The experimental method is derived from a novel formula for the effective thermal conductivity of a vapor chamber and functions to calculate its thermal performance. Results show that the maximum heat flux is over 100 W/cm2 , and the effective thermal conductivity is many times higher than the copper heat spreaders. The maximum effective thermal conductivity is 870 W/m°C according to the novel formula, and comparing it with the experimental value, the calculating error is no more than ± 3%.
