Two rectangular block-like elements as an electronic module are positioned in a parallel-walled channel and cooled by forced convection airflow. A metal plate without holes as a barrier protrudes above the plane of the modules, 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 gap, G, between the barrier and the channel and
more » ... , L, between the module and the barrier were measured. In the presence of the barrier, the heat transfer coefficient at the 2nd row module is enhanced, but is diminished at the 1st row module. Nusselt numbers are correlated as a function of Reynolds number and G/L.
