Influence of Time on Thermo sensitivity of Copper /Paraffin Thermo sensitive Composite and Development of Testing Device

摘要

Nano copper /paraffin thermo sensitive composite was prepared by high energy milling and pressed into a glass cylindrical tube by using thermoforming process. Thermo sensitivity of the thermo sensitive composite was tested by thermo sensitivity tester which is developed by us. The composite particles with good cladding effects, prepared by high energy milling, arrange close together. Copper particles have no damage on the structures of paraffin. The thermal conductivity of thermo sensitive composite is enhanced with the increase of mass ratio of copper powder.
