Rather, the examples described herein have been provided merely to illustrate some of the many possible ways to implement the methods, devices, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0028] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, it may be directly “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on,” “directly connected to,” “directly coupled to,” “directly over,” or “directly covering” another element, there may be no other elements present between them.

Preferably, the first thermal insulation device 21 can be a multi-layer box body structure, and the first pure water container 20 is arranged in the innermost layer. Since the water triple point reproduction experiment requires the temperature uniformity and temperature stability of a single container to be better than ±0.05K, the water triple point reproduction device can use a multi-stage temperature control method to control the temperature of the first pure water container 20, that is, the multi-layer box body structure of the first thermal insulation device 21 can be temperature-controlled step by step.

[0045] Further, preferably, Figure 5 As shown, in an embodiment, the outer surface of the first insulation device 21 can be wrapped with a multi-layer insulation structure, and an insulation device box can be disposed within the first insulation device 21.

The perturbation system 3 can include a first cold plate 31, a first guide rail 33, a first driving assembly 35, a second cold plate 32, a second guide rail 34 and a second driving assembly 36. The first cold plate 31 can be installed at the bottom of the first heat insulation device 21, and the first cold plate 31 can be in heat conduction connection with the heat dissipation component (the first cold plate 31 can be communicated with the third cold plate 10). The first purified water container 20 can be in heat conduction connection with the first cold plate 31 through the heat pipe 23, and specifically, the second end of the heat pipe 23 can be bonded on the first cold plate 31 (i.e. the heat pipe 23 is indirectly in heat conduction connection with the third cold plate 10 through the first cold plate 31). The first guide rail 33 can be installed on the third cold plate 10. Specifically, the first guide rail 33 can be arranged along the length direction of the box body 11, and the first guide rail 33 can be installed on both sides of the width direction of the first cold plate 31, and the first cold plate 31 is slidably installed on the first guide rail 33, so that the first purified water container 20 can slide along the first guide rail 33 following the first cold plate 31.

Similarly, the second cold plate 32 can be installed at the bottom of the second heat insulation device 22, and the second cold plate 32 can be in heat conduction connection with the heat dissipation component (the second cold plate 32 can be communicated with the third cold plate 10). The second purified water container can be in heat conduction connection with the second cold plate 32 through the heat pipe 23, and specifically, the heat pipe 23 can be bonded on the second cold plate 32 (i.e. the heat pipe 23 is indirectly in heat conduction connection with the third cold plate 10 through the second cold plate 32). The second guide rail 34 can be installed on the third cold plate 10. Specifically, the second guide rail 34 can be arranged along the length direction of the box body 11, and the second guide rail 34 can be installed on both sides of the width direction of the second cold plate 32, and the second cold plate 32 is slidably installed on the second guide rail 34, so that the second purified water container can slide along the second guide rail 34 following the second cold plate 32. The second driving assembly 36 can be installed on the third cold plate 10. The second driving assembly 36 is used for driving the second cold plate 32 to move along the second guide rail 34. In this way, the perturbation system 3 can drive the water container part 2 to move along the length direction of the box body 11.

[0049] Further, preferably, as Figure 6As shown in the embodiment, the first driving assembly 35 and the second driving assembly 36 can be a crank slider mechanism. The crank slider mechanism can include a motor and a connecting rod. The motor can be bolted on the third cold plate 10, and the connecting rod can connect the motor with the first cold plate 31 and the second cold plate 32. When the motor rotates, the connecting rod will drive the first cold plate 31 to reciprocate along the first guide rail 33, and drive the second cold plate 32 to reciprocate along the second guide rail 34, so that the purified water in the first purified water container 20 and the purified water in the second purified water container can easily enter the solid state.

[0050] In addition, preferably, as Figure 6 As shown in the embodiment, since the perturbation system 3 is a moving part, in order to prevent the spacecraft from unnecessary shaking with the first purified water container 20 and the second purified water container during the launch process, the perturbation system 3 can also include a locking component 30. The locking component 30 can be installed at the end of the length direction of the first cold plate 31 and the second cold plate 32. The locking component 30 is used to fix the first cold plate 31 and the second cold plate 32 to the side wall of the box body 11, and then fix the position of the first purified water container 20 and the second purified water container. Specifically, the locking component 30 can be a puller (i.e. a memory alloy puller), when the locking component 30 is powered, the SMA wire of the puller is heated and shrunk, generating a restoring force to release the ball lock mechanism to release the pin, so as to be fixedly connected to the side wall of the box body 11. During the launch of the spacecraft, the locking component 30 can limit the position of the first cold plate 31 and the second cold plate 32, and can bear a certain launch load. When the perturbation system 3 needs to work, the locking component 30 is released to limit the position.

Specifically, the temperature measuring and controlling system can include a temperature sensor and a measuring and controlling unit 40.

In addition, the temperature sensor can also be installed in the heat insulation device box. The temperature sensor installed in the first purified water container 20 and the second purified water container can be a platinum resistance PT1000 (temperature measurement accuracy can reach 0.001K), and the temperature sensor installed in the heat insulation device box can be a thermistor, so as to realize multi-stage temperature control. Since the temperature sensor is the core temperature measuring element, in order to ensure the accuracy and stability of the measurement, the temperature measurement accuracy needs to be at least one order of magnitude higher than the temperature control accuracy. The measuring and controlling unit 40 can be installed on the bottom plate of the box body 11, and the measuring and controlling unit 40 can be in conductive connection with the temperature sensor and the semiconductor refrigeration piece 200 (can be connected through a wire). The measuring and controlling unit 40 can realize multi-stage temperature control by controlling the power supply of the semiconductor refrigeration piece 200, so as to finally make the purified water reach a suitable temperature.

[0052] In use, the water triple point reproduction device controls the temperature of the first purified water container 20 and the second purified water container through the temperature measuring and controlling system, and realizes multi-stage temperature control through the first heat insulation device 21 and the second heat insulation device 22. The disturbance system 3 drives the first purified water container 20 and the second purified water container to move in the box body 11, so that the purified water is easy to enter the solid state. The water triple point reproduction device is reliable in equipment, can meet the interface requirements of the space station as a whole and the needs of scientific experiments, and can realize automation, so as to realize the water triple point reproduction under microgravity conditions.
