The cooling capability in compact electronic equipment in natural convective flow fields has been investigated. The relationship between clearance of a channel and natural cooling capability was obtained. Temperature and velocity measurements were carried out using a channel model of electronic equipment having a vertical duct of rectangular section. The channel model was constructed with two copper walls and two transparent acrylic walls. The clearance between the copper walls was used as a parameter for the channel model. Velocity profiles of natural cooling flow in the channel were quantitatively measured using particle image velocimetry (PIV). The temperature and velocity results demonstrated that changes in the velocity profiles and temperature profiles closely depend on the wall clearances. The clearance from 8mm to 10mm is the best size for the natural cooling capability in the channel in this study.
