摘      要:This paper presents an experimental investigation of the influence of a transversal flow deflector on the cooling of a heated block mounted on a flat *** deflector is inclined and therefore it guides the air flow to the upper surface of the *** configuration is simulating the air-cooling of a rectangular integrated circuit or a current converter mounted on an electronic *** electronic component is assumed dissipating low heat power,as such,air forced convection is still a sufficient cooling way even without fan or heat sink on the *** measurements are given by hot and cold wires anemometers and by an InfraRed *** results give details of the effects of the deflection on the hydrodynamic and the thermal fields on and over the block for different inclination *** show that the deviation caused by the deflector may significantly enhance the heat transfer from the *** is also able to avoid local overheating of the electronic *** heat transfer rate and homogenised temperature are shown to be obtained with an inclination angle =30°.
