Optimization of Cooling Air Flow for Improved Heat Dissipation through Radiator

Abstract

<div class="section abstract"><div class="htmlview paragraph">Environmental Protection Agency (EPA) study indicates that a typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. The Automotive industry facing a challenge of meeting stringent CO2 emission targets of 95g per kilometer for passenger car application. Thermal efficiency of internal combustion engine is one of the crucial technical parameters, which plays an important role in meeting CO2 emission targets. Global Automotive industry tends to achieve for cleaner, lower emission, low noise &amp; improved performance for automotive products. Engine Overheating is affecting thermal efficiency &amp; thus brake specific fuel consumption of the vehicle. Radiator is one of the critical components in Engine cooling system, which will ensure optimum operating range of internal combustion engine through precise control on coolant flow rate by Thermostat valve. Heat dissipation through radiator is directly proportional to volumetric mass flow rate of atmospheric air. The demand for more powerful engines in smaller hood spaces has created a problem of insufficient rates of heat dissipation in automotive radiators. Upwards of 33% of the energy generated by the engine through combustion is lost in heat. By taking motivation from this strategic challenge, innovative concept had proposed with mechanical &amp; automatic layout.</div></div>
