建立了温度敏感型磁流体无泵流冷却回路实验系统,采用粒子示踪测速技术(PIV)对整个回路中的流场进行了测量,实验研究了不同加热、冷却功率下回路的流动传热性能,分析了磁场及温度场的协同作用对回路性能的影响.结果显示:温度敏感型磁流体在外加适当磁场及温差时可以持续流动,将热量从热端传递到冷端并循环工作;系统冷却性能受到磁场及温度场的协同作用影响.
A thermosensitive magnetic fluid pump-less cooling circuit experimental system was set up. The flow field in the entire circuit was measured by particle tracer velocimetry (PIV). The flow and heat transfer performance of the circuit under different heating and cooling power was experimentally studied , The influence of the synergistic effect of the magnetic field and the temperature field on the circuit performance was analyzed.The results show that the temperature-sensitive magnetic fluid can continuously flow when applied with appropriate magnetic field and temperature difference, and transfer the heat from the hot end to the cold end and circulate. Performance is affected by the synergistic effect of the magnetic and temperature fields.
