Abstract
Automotive radiators are equipment charged with dissipating the thermal energy of internal combustion engines to the environment. Both the internal combustion engines and the automotive radiators have evolved together over the years, due to the direct relation between the power produced by the engine and the energy that must be dispersed from it. Currently, the thermal dissipation capability in automobiles is considered as the main obstacle to the implementation of more powerful engines in the new models. The present work describes a stationary test bench to evaluate the thermal exchange of automotive radiators. This bench consists of a wind tunnel, which simulates the car in motion, and a heating system, which simulates the heat to be rejected from the engine. The methodology used to test the truck radiator followed the guidelines of the Japanese standard JIS D-1614: 1991 Radiators for automobiles - Test method of heat dissipation. A truck radiator provided by an automotive company has been thermally analyzed, thus determining its thermal dissipation for various coolant flows as a function of the imposed airflow. Additionally, the pressure drop caused by the radiator in wind tunnel and cooling system were all estimated. Finally the results were presented in the format stipulated by the abovementioned standard. This work consists of the initial stage of a project that aims to improve the thermal efficiency of automotive radiators.
