[0033] Working principle: Before using this split-type heat preservation test box, it is necessary to first connect the first air extraction pipe 20 and the second exhaust pipe 25 to the heat preservation box 5, then place the heat preservation box 5 above the substrate 2, and then operate the first motor 11 to move the two moving plates 12 inward.

Then, by rotating the threaded member above the fixing member 15, the fixing member 15 fixes the heat preservation box 5 above the substrate 2;

[0034] During the high-temperature test of this split-type thermal insulation test chamber, the electric heater 31 can be operated first to heat the gas inside the sealing plate 30. Then, the second air extraction pump 23 is operated, so that the second air extraction pipe 24 extracts air from the second air supply pipe 34 and the second ventilation pipe 32.

[0036] During the low-temperature test of this split-type thermal insulation test chamber, the second air extraction pump 23 can be operated first, so that the second air extraction pipe 24 extracts air from the first air supply pipe 29 and the first ventilation pipe 27. Then, the cooler 26 is operated to cool the gas extracted by the second air extraction pipe 24. Then, in cooperation with the second exhaust pipe 25, the cold air is discharged into the interior of the insulation box 5, and thus the low-temperature test work on the objects inside the insulation box 5 can be carried out. Then, the first air extraction pump 18 is operated, so that the first air extraction pipe 20 extracts the cold air inside the insulation box 5, and then, in cooperation with the first exhaust pipe 19 and the first guide pipe 17, the cold air is discharged back into the interior of another gas storage cavity;

[0037] It should be noted that when there is cold air inside the gas storage cavity, when the second air extraction pump 23 extracts the cold air, the second guide pipe 22 can be used to extract the cold air inside the gas storage cavity.
