POSSIBLE DETERMINATION OF THE DIRECTION OF THERMAL FLOW USING AN INDUCTIVE THERMAL SENSOR

The paper presents a method and device for the possible determination of the direction of thermal flow and temperature in systems with a small elementary volume. Determining the direction of heat flow for elementary systems is quite a serious problem. To solve the problem, an inductive system is used: an inductive sensor, or more precisely, an inductive thermal sensor with a small volume, the area of ​​the thermal element of which can reach 10-11 m2. Moreover, the presented device makes it possible to do this both in the case of direct contact and without contact. For both cases, their general views with their respective elements are provided. At the points where the temperature measurement is carried out with the help of direct touch, the distance between them is limited by the size of the thermal element, and in case of non-touch measurement, it is limited by the wavelength of light. The types of the presented system are given. The thermal element in the sensor is very thin, on the order of 10-6 m. For this reason, the temperature distribution according to the thickness can be assumed to be homogeneous. With the help of the sensor, the temperature or heat flow distribution according to (x,y) is determined, then with the help of a simple gradient, the direction of the heat flow.
