Abstract
The aim of this work is to study the behavior of an engine cooling radiator in transient state, with circulation of heated water. An experimental apparatus was constructed with the radiator inside a wind tunnel. The water is pumped from a small water tank to a heater, passes through the heat exchanger, and returns to the tank. The tests were carried out with constant water and air flows, and the heater was set on for some time. The temperatures of the radiator, the air and the water were measured into several places with thermocouples and a thermal camera, besides the flows of water and air. The temperatures increase very fast just as soon as the heater is turned on. After that, the temperatures increase slowly while the whole system is getting warmer. The steady state in reached after 15 min. These results might be useful in the project of a vehicle cooling system under transient conditions.
