摘　　要：提出了一种由内流液冷式制动电阻构成的制动电能耗散系统,用于解决混合动力车辆制动过程中需要耗散制动电能的问题.对制动电能耗散过程中的能量转换、传递和耗散过程进行了理论分析及计算,并应用到具体车型案例中.结果表明,该系统能够很好地满足车辆制动能量的耗散需求,且不会引起发动机冷却系统散热不足的问题.In this paper,an internal flow liquid cooled resistance was proposed to solve the problem of power dissipation during the braking process of the hybrid vehicle.The energy conversion,transfer and dissipation are analyzed and calculated in the process of brake power dissipation.After applying the proposed scheme in a specific vechicle,the results show that using the internal flow fluid cooled resistance technology can effectively meet the demand for braking power dissipation and will not cause the problem of insufficient heat dissipation.
