THERMAL FLUX TRANSMITTER Russian patent published in 1994 - IPC

FIELD: thermal measurement technologies. SUBSTANCE: thermal flux transmitter has heat receiver in the form of disk from low-heat conducting material. On top, bottom and on the side surface the disk carries respectively heat equalizing plates and bushing of thickness δ selected from the relationship d/R=0,023-0,04/R = 0.023 - 0.04, where R - the radius of the heat receiver. The heat equalizing plates and the bushing are fabricated from the material whose thermal conductivity is higher by two orders of magnitude than thermal conductivity of the heat receiver. Three temperature-sensing members are mounted in tandem thickness-wise along the axis of the heat receiver. The temperature of the receiving surface and the sought-for thermal flux are determined by measuring temperature in the heat receiver with subsequent solution of the inverse heat conductivity problem by means of convolution-type integral equations. EFFECT: higher measurement accuracy due to allowance for two-dimensional character of temperature field in heat receiver. 2 dwg
