摘　　要：粉碎机械冷却系统中管带式散热器是不可缺少的零部件之一,通过对粉碎机散热器进行改进,合理匹配散热器的散热量与功率,能够保证粉碎机稳定安全运转,提高工作可靠性,延长粉碎机使用寿命。建立流体动力学数学模型、几何模型,根据数学模型进行网格划分和边界条件设置,利用Fluent软件对散热器进行温度场仿真分析。结果表明:对于管带式散热器的翅片,增大振动速度能够显著提高传热效果;在风速大于5 m/s的条件下会起到削弱传热的作用;利用振动作用可以增强管带式散热器的传热效果,提升散热性能。Tube-belt radiator is one of the indispensable parts in the cooling system of crushing machinery.By improving the radiator of the crusher,the reasonable matching of the heat dissipation and power of the radiator can ensure the stable and safe operation of the crusher,improve the reliability of the work,and prolong the service life of the crusher.The mathematical model and geometric model of fluid dynamics were established.According to the mathematical model,the mesh division and boundary condition setting were carried out.The temperature field simulation analysis of the radiator was carried out by Fluent software.The results show that for the fins of the tube-band radiator,increasing the vibration speed can significantly improve the heat transfer effect,and it will weaken the heat transfer when the wind speed is greater than 5 m/s.Using the oscillation effect can enhance the heat transfer effect of the tube-band radiator and improve the performance of the radiator.
