Investigationof the influence of distance between fan and radiator surface on the efficiency of cooling system
Abstract
Today, electric vehicles are the most widespread among vehicles powered by alternative energy sources. During the operation of the electrical components of the vehicle, a large amount of heat is released, so it becomes necessary to use cooling systems to maintain the required temperature range of the electrical components. Computer simulation makes it possible to carry out studies of various processes in vehicles with high accuracy at lower material and time costs. The main purpose of the presented work is to increase the efficiency of heat dissipation of the radiator of the cooling system during fan operation by increasing airflow when changing the distance between surface of radiator and fan. The results of computer simulation and full-scale experiment to determine the optimal distance between the radiator and the fan at different speeds are presented. As a result of the study, it was found that when the casing with the fan was removed by 10 mm from the radiator, compared to the original version, the air consumption increased by an average of 13%. The results of computational studies were confirmed by experiment.
