摘要：
The aim of this study is to inhibit the natural convection heat transfer on a perpendicular cooling plate. The heat transfer coefficients at several points on the cooling plate were obtained by using multi-type thermocouple method. In the experiment, one plate with periodic grooves in a zigzag state and another with a flat plate surface were used. Each heat transfer characteristic along the plate was compared. Furthermore, a grooved plate a deeper depth was tried in the experiment. The heat transfer coefficient of the plate with the grooves became smaller than that of the flat cooling plate as the thermal boundary layer developed in the grooves.
