The Influence of Compact Heat Exchanger’s Position on Electric Formula Car Cooling System

Several studies have been conducted since a cooling system using the compact heat exchanger on electric formula cars. This is to determine its capability because when the cooling system of a vehicle does not function optimally, it causes the engine to overheat. Therefore, this research aims to provide more information on the electric formula car radiator, focusing on its installation position. Simulation modeling was done by first simplifying the fin part to become a porous medium. This was performed in two stages, firstly, by creating a one-unit cell fin simulation, and the results were used to determine the parameters of the porous medium. Then, completing the modeling of the radiator, to determine the effect of the device's angle on airflow, using various positions on the x-axis. In addition, the airflow velocity was varied with an inlet temperature of 30˚C. The results showed that the effect of air velocity was proportional to the temperature distribution of the hot fluid on the radiator. Also, the best position of the compact heat exchanger to absorb heat was at the 60˚ elevation to the x-axis, with a maximum energy transfer of 7436 W.
