以R600a-纳米铝为工质的热管散热性能试验研究

Test Investigation of Heat Transfer Performance of Heat-tube Charged with Nanofluid of R600a and Nano-Aluminium

采用表面修饰技术和添加分散剂的方法制备了均匀而稳定的R600a-纳米铝纳米流体,将其充注到半导体冰箱散热热管中以提高热管散热性能,采用红外热像仪研究了热管温度分布,利用冰箱性能试验室测试了半导体冰箱整机性能,试验表明以R600a-纳米铝为工质的热管散热性能优于普通热管散热性能,并分析了纳米流体提高热管散热性能的原因。

Surface-modifying and dispersant technology makes a uniform and stable nanofluid of R600a and nano-Aluminium available. The heat-tube of semi-conductor refrigerator is charged with nanofluid to improve its heat transfer performance. Infrared thermal image instrument is used to investigate the temperature distribution of heat-tube and refrigerator test room is used to test the performance of semi-conductor refrigerator. It shows the heat transfer performance of heat-tube charged with nanofluid of R600a and nano-Aluminium is better than that of heat-tube charged with R600a. The reason why nanofluid improves the heat transfer performance is also analyzed.
