Abstract
This study describes a possibility of an improvement of cooling performance on the surface of heating elements by using an intermittent jet flow like a geyser in nature. In this report, we tried to evaluate the heat transfer performance of the intermittent impingement jet on heating surface, which simulates the surface of the cooling channel or the electrical chips. We developed the flow tunnel which can generate the intermittent jet on the heating surface and the heat transfer experiment was performed. Through the experiment, it was found that the intermittent impingement jet has almost the same heat transfer performance as the steady impingement jet regardless of the decrease of the time-averaged supply flow rate.
