Abstract
At present, cooling technologies for most computer products reply on coolers and thermal modules are more and more important. The abilities of heat removal of coolers and thermal modules depend on the thermal resistance. Advanced cooling technologies in the form of heat pipes are already widely used during this decade. However, the full test for all the components does mean the thermal modules set or the cooler not defect. In another word, the full test procedures for the thermal modules or the cooler in the factories are necessary. Normally, completing the thermal resistance measurement takes a long time which is above 30 minutes traditionally. In this paper, we propose a quick thermal test theory and novel instrument that have been developed for measuring the thermal resistance of coolers and thermal modules. The continue type design can achieve the thermal resistance measurement on the mass production line. In order to obtain the compared deviation, the comparisons between theoretical prediction and traditional standard method are also focus in this study. In addition, this study also discusses the reliability in different coolers. The method is based on the evaluation of the thermal resistance, obtained by the Q.T.T. theory. The standard deviation of experiment results is in about 5％. The repeatability of experiment results is within 10%. This instrument can accomplish measurement effectively in 30 seconds. In conclusion, the main advantages of this method are the simplicity and speedy.
