METHOD AND DEVICE FOR THERMAL IMAGING OF HEAT REMOVAL CHARACTERISTICS Russian patent published in 2019 - IPC G01K13/02 G01J5/60 

FIELD: measurement technology.

SUBSTANCE: invention relates to measurement of thermal state of solid body surface and gas flow. Method for thermal determination of heat release characteristics, including measurement of temperature fields of solid body and gas stream, wherein temperature measurement of gas flow is carried out synchronously with measurement of temperature field of solid body by placing in gas flow of converter temperature in form of a grid. In cross-hairs of temperature converter, which is installed before analyzed process surface of solid body with possibility of its movement in vertical and horizontal planes, sensors with a coefficient of heat conductivity different from coefficient of thermal conductivity of the threads of the temperature converter are installed, and a thermal image of the thermal fields of the surfaces of the sensor and the temperature converter in different points of the gas flow is captured. A device for thermal determination of heat-transfer characteristics, comprising a temperature transducer made in the form of a grid of threads with a thermal indication coating, and is equipped with a thermal imaging camera. Temperature transducer is arranged inside frame, which is installed on posts with possibility of its vertical movement with subsequent attachment to them, at that, on the temperature converter the temperature field sensors are rigidly fixed in a staggered order, made in the form of plates of an arbitrary shape, having on their central axis ledges similar to the shape of the plate, wherein ratio of plate thickness to projection is 1:2, converter area S_con to total area of sensors S_sen and to area of ledges S_led makes proportion S_con:S_sen:S_led=(34…40):(3…4):(1…2).

EFFECT: high accuracy of measuring gas flow temperature while simplifying the measurement process.
