One circular cylinder as an electronic component is positioned in a parallel-walled channel and cooled by forced convection airflow. A metal plate with circular holes as a barrier blocks the channel, which is intended to function as a cover for protecting them from mechanical or electromagnetic damage, or as a thermal control device. Per-module heat transfer coefficients in the presence of the barrier of various hole diameter d, porosity, and distance L, between the cylinder and the barrier were measured. In the presence of the barrier with holes, the heat transfer coefficient at the cylinder was improved. Nusselt numbers are correlated as a function of Reynolds number and L/d.
