ABSTRACT:
In order to measure the in-plane thermal conductivity of a sample plate, the plate is placed in a prefabricated device containing (1) a pair of thermocouples, (2) a source of heat flow into the plate, (3) a heat sink of the heat flow having an open cavity, (4) a taut membrane, on which the source of heat flow and the thermocouples are bonded, located on the resilient filling, (5) a resilient filling of thermally insulating material located underneath the membrane, in the cavity of the heat sink, and (6) a thermally insulating medium covering the plate and exerting a compressive force on it.
