4 Principles
Fix the standard sample with known thermal conductivity between two measuring heads with set temperature (see Figure 1), so that the two ends of the sample are in contact with the measuring head end:
The measuring head is divided into a heating end (hereinafter referred to as "hot end") and a cooling end (hereinafter referred to as "cold end"): The set temperature of the hot end is
40℃±0:1℃, the cold end set temperature is 20℃±0:1℃: The temperature at both ends of the head to be measured is stable at the set temperature, and the voltage value at the hot end is within
When it remains unchanged for more than 10 minutes, record the heating voltage value of the hot end: By measuring standard tests of the same material, same diameter, and different heights
sample, draw the U-λ/h curve (see Figure 2), where U is the hot end voltage value, in mV; λ is the thermal conductivity of the standard sample, in unit
W/(m·K); h is the height of the standard sample, in mm: Then, use the test sample instead of the standard sample for testing, and the head temperature to be measured
When the temperature is stable at 40℃±0:1℃ and 20℃±0:1℃ respectively, record the heating voltage value of the hot end, and then, with the help of the drawn U-λ/h curve
Figure, Calculate the thermal conductivity of the test specimen:
The thermal conductivity of the standard sample material should be similar to the thermal conductivity of the tested sample material:
