This paper describes the effects of frame and inlet sizes of an electronic casing on the cooling fan performance. The performance of air-cooling fans is defined by their P-Q characteristics. Recent studies report that P-Q curves of cooling fans depend considerably on their operational environments. It is impossible for accurate CFD (Computational Fluid Dynamics) analyses to be performed on the thermal design of electronic equipments, including fans. In this study, we measured a fan performance in some frames and explored effects of environment for their P-Q characteristics, especially effects from area of frame and cooling air inlet sizes. From experimental results, it was found that the fan P-Q characteristics, especially flow rate were affected strongly by inlet sizes.

Water-silicone oil emulsion with a silane coupling agent was used as a phase change material. Using stainless steel vessels coated with PFA resin, experiments of forming ice with stirring were carried out under various conditions of the temperature of brine for cooling and the composition of emulsion. We investigated the correlation between cooling heat flux and ice adhesion to the cooling surface in the ice formation process. The following results were obtained, (a) Silicone oil has the effect of preventing the formed ice from adhering to the cooling surface, (b) Under a condition of the same concentration of the additive, the maximum cooling heat flux without adhesion in the case of water fraction of 80vol.% was larger than that in the case of 100%.
