Thermal conductivity tester works:
Type thermal conductivity tester, using double test piece measuring device, protective hot plate group: including heating unit, cooling unit. The heating unit shall be divided into a metering unit in between and a protective unit surrounding the metering unit separated by a gap, and equipped with thermal insulation. The hot unit adopts double hot surface heaters. The cold plates are arranged symmetrically with the double hot surfaces. The thickness of the test piece sets the space for moving the cold plate. The test piece is placed vertically in two flat plates with constant temperature parallel to each other. In the steady state, the measurement part of the test piece has a constant heat flow. By measuring the one-dimensional constant heat flow Q flowing through the metering unit, the area A of the metering unit, and the temperature difference T between the cold and hot surfaces of the test piece, it can be calculated. According to the thickness of the test piece, the thermal resistance R of the test piece can be accurately calculated.
