摘要: A double-sided guarded hot plate apparatus (GHP) is specifically designed, fabricated, and constructed for the measurement of thermal conductivities insulation specimens operated down to liquid nitrogen temperature (−196 °C), at different controlled pressures from 0.005 Pa 0.105 MPa. The placed in this are 300 mm diameter various thicknesses ranging 4 40 mm. traditional GHP terms structure, supporting heating method. details design construction plate, cold plates, suspensions, clampings, vacuum chamber system presented. methods temperatures, input power, meter area, thickness given. calibrated with teflon plates as sample maximum deviation published data about 6% conductivity. uncertainties also discussed paper.
