In this study, the natural cooling of electronic equipments has been studied experimentally. The natural convection between two vertical walls modeling printed circuit boards was investigated. Velocity fields between the walls were measured using a PIV and a cooling capacity was estimated as functions of the board spacing and a heating power. It was found that the cooling capacity was small when the board spacing was less than 10mm under the condition examined. Measured velocity profiles were compared with available analytical and experimental data and the validity of the PIV measurement was confirmed.
