[0055] figure 1 It is a schematic diagram of a sample tube of a thermal conductivity measurement device according to an embodiment of the present invention. Such as figure 1 As shown, the sample tube used for accommodating the sample 4 includes: an insulating sleeve 1, a heating device 2, a first temperature sensor 3, a second temperature sensor 5, and a pyroelectric semiconductor 6. Optionally, the sample tube may also include a heat dissipation block 7.
[0056] Such as figure 1 As shown, the thermal insulation jacket 1 constitutes a barrel-shaped structure with one end closed, such as a barrel shape or a square barrel shape, for accommodating the heating device 2, the first temperature sensor 3, the sample 4, the second temperature sensor 5, and the thermoelectric semiconductor 6. One end of the thermal insulation sleeve 1 is open and the other end is closed. The openings and closures mentioned here are for heat conduction, and closure refers to thermal closure, that is, the ...
