Research on Braking Resistor of Hybrid Electric Armored Vehicle
In the present paper, the heat transfer process of the braking resistor is analyzed. The corresponding theoretic model is proposed and solved numerically. The standard laminar model and constant heat flux method are employed to compute the heat transfer in the parallel channels between the braking resistor strips. The numerical computations for different conditions are performed. The corresponding heat transfer relationships among the convective heat transfer coefficient, thermal boundary layer thickness, cooling air outlet temperature and braking resistor surface temperature are studied according to the computed results. Finally, the theoretical heat transfer model of flow in the braking resistor case is used to investigate the variety of the resistor temperature of the practical braking resistor applied in some type hybrid electric armored vehicle. The vehicle operating test result shows that the uncertainty of the theoretic calculation model is within 15％, which can fulfill the engineering design requirement
