摘　　要：应用标准k-ε双方程和能量方程,对比分析了原结构和加装顺排与叉排销式强制散热结构时缓速器转子盘单个风道的空气流动和散热状况。对加装顺排散热销后转子盘内、外表面温度的变化进行台架试验,结果表明加装顺排散热销结构可有效降低转子盘最高平衡温度和温度上升速率,提高缓速器制动稳定性。The air flow and heat dissipation behaviors in a single air passage of rotor disc in an eddy current retarder with original gtructure and attached inline and staggered pin fins structures for forced heat dissipation are comparatively analyzed using standard k-ε double equations and energy equation. The changes of temperatures on beth sides of rotor disc with inline pin fins attached are measured by bench test. Analysis and test results show that both highest stable temperature and temperature rising rate of rotor disc with inline pin fins attached can be effectively reduced, and hence the braking stability of retarder can be improved.
