Natural cooling capability in a vertical channel modeling compact electronic equipment was investigated by experiment and numerical simulation. Temperature rise of the heating walls of the channel model and velocity profiles of natural air flow in the channel were obtained. The effects of the clearance between the heating walls on the natural cooling capability were discussed. The clearance was varied from 4 mm to 20 mm in this study. It is clarified that the optimum size of the clearance existed between 8 mm to 10 mm.
