Abstract
Abstract An experimental apparatus to measure the thermal contact conductance (TCC) between interfaces of two contact solid materials was introduced, and a new compensating heater was proposed to better achieve the one-dimensional axial heat transfer. A practical engineering example was used with pressed pairs of GH4169/K417 contacts in the range 160∼280 °C and 60∼180 MPa to demonstrate the applicability of the experimental apparatus. The measured values of TCC with and without compensation heater were studied and compared. The results show that the measured TCC with compensation heater is larger than that without compensation heater under the same condition and the compensation heater works better at high temperature.
