High temperature of the radiator group is harmful to the power system and hydraulic system. In order to improve the heat dissipation performance of the loader, the flow field characteristics of the cooling chamber are analyzed by simulation and heat balance test. Firstly, the mathematical model of heat flow is established. Secondly, the flow field in the cooling chamber under different speeds is simulated based on CFX. And then the influence of fan position and internal flow field distribution on radiator performance is studied. Through the simulation of four different distances, it is concluded that the optimal distance between cooling fan and radiator is 76 mm. Finally, the heat balance test system based on wireless sensor network is established, and the simulation results are verified. The test results show that the heat dissipation performance of the whole machine meets the requirements after optimization. In this paper, the proposed scheme can dynamically adjust the heat dissipation performance and make the loader excavator in an efficient and energy-saving operation state.

基于仿真和无线传感器网络的智能装载机热平衡系统

散热器组的高温对动力系统和液压系统有害。为了提高装载机的散热性能,通过模拟和热平衡试验分析了冷却室的流场特性。首先,建立了热流数学模型。其次,基于CFX,模拟了不同速度下冷却室内的流场。然后研究了风扇位置和内部流场分布对散热器性能的影响。通过对四个不同距离的仿真,可以得出结论,冷却风扇与散热器之间的最佳距离为76 mm。最后,建立了基于无线传感器网络的热平衡测试系统,并验证了仿真结果。测试结果表明,整机的散热性能符合优化后的要求。本文提出的方案可以动态调节散热性能,使装载机挖掘机处于高效节能的运行状态。
