A circulation pipeline 7 is provided on the side of the cooling plate 5 away from the test surface. A cooling medium circulates in the circulation pipeline 7. In this embodiment, the cooling medium is specifically cooling water. During use, the two ends of the circulation pipeline 7 are connected through a pump body and a pipeline to achieve circulation.

[0033] It further includes a heat insulation plate 8 and a displacement device 9. The heat insulation plate 8 is arranged on the side of the cooling plate 5 away from the mounting base 1. The displacement device 9 is connected to the heat insulation plate 8 and drives the heat insulation plate 8 to move, so as to drive the heat insulation plate 8 to block / open the test hole 6.

[0034] During use, the sample is fixed on the test surface through the clamping plate 4. Further heat radiation acts on the sample through the test hole 6. At this time, the radiation heat protection performance of the sample is detected through the temperature measurement unit 2. At the same time, during the test process, the circulating medium in the circulation pipeline 7 circulates continuously, so as to cool down the heat radiation dissipated from the surrounding environment of the mounting base 1, reduce the influence of this part of heat radiation on the temperature measurement unit 2. At the same time, after a single test is completed, the mounting base 1 can be quickly cooled through the circulation unit to improve the detection efficiency.

[0035] At the same time, after the detection is completed, the displacement device 9 can drive the heat insulation plate 8 to move, so as to block the test hole 6, and further avoid the residual heat radiation acting on the sample and affecting the test result.

[0039] In the initial state, the relaxation side 19 corresponds to the mounting seat 1. At this time, the spring 16 is in a relaxed state, and the relaxation side 19 does not abut against the substrate mounting seat 1.

The driving mechanism 21 is used to drive the pressing head 22 to abut against the side of the mounting seat 1 away from the cooling plate 5 to cooperate with the cooling plate 5 to respectively abut against and fix both sides of the mounting seat 1.

[0042] Through the setting of the pressing assembly, the rapid disassembly and assembly of the mounting seat 1 and the heat insulation frame 20 can be realized, and thus the sample installation is facilitated.

The two ends of the locking block 26 are respectively rotatably connected to the base 23 and the middle section of the wrench 24.

[0044] During use, by pressing the wrench 24, the pressing rod 25 is driven by the wrench 24 to rotate, so that the pressing head 22 presses and fixes one side of the mounting base 1. At the same time, when the wrench 24 rotates, the locking block 26 can be driven to rotate, so that the locking block 26 and a part of the wrench 24 are in a straight line state to complete the locking of the position of the wrench 24.

[0045] Through the driving mode of the wrench 24 and the pressing rod 25, rapid pressing and fixing of one side of the mounting base 1 can be realized to achieve rapid disassembly and assembly.
