Experimental and numerical study of a water-stirring radiator

Abstract

In this paper, a water-stirring radiator is presented, which possesses a sealed water chamber and a stirrer. Different from the conventional water-stirring radiators, there are no micro pump and connected channel in the present radiator, but the stirrer driven by a motor stirs water to cool the heat source. A set of experiments and FLUENT simulations were carried out to examine the performances, and a comparison between experimental and simulated values was presented.
