Meanwhile, the other side of the second partition layer 6, one side of the first partition layer 10, the inner pipe wall of the outer pipe 1 and the outer pipe wall of the inner pipe 7 enclose a heat transfer cavity unit.
In each of the above embodiments, the first barrier layer 10 and the second barrier layer 6 are both physically sealed barrier layers, preferably of various thermally insulating or low thermal conductivity materials.
In the above embodiments, in order to maximize the heat exchange area of the heat pipe cavity, the inner pipe 7 and the outer pipe 1 are arranged eccentrically, i.e. the axes of the two are not coincident. There are positions with the shortest distance and the longest distance between the outer pipe wall of the inner pipe 7 and the inner pipe wall of the outer pipe 1, and first spacers 10 are provided at both positions, and the two first spacers 10 are located in the radial direction of the inner pipe 7 and the outer pipe 1 at the same time.
Specifically, a first interlayer 10 is disposed at the position where the distance between the outer wall of the inner tube 7 and the inner wall of the outer tube 1 is shortest, and a second first interlayer 10 is disposed at the position where the distance between the outer wall of the inner tube 7 and the inner wall of the outer tube 1 is longest. Meanwhile, the second interlayer 6 is engaged with the first interlayer 10, so that a large space can be reserved for the first heat transfer chamber unit 3 and the second heat transfer chamber unit 8.

On the basis of the above embodiments, in order to prevent the filling rate of the second working medium 5 in the outer tube 1 from being too high, in this embodiment, the liquid level of the second working medium 5 needs to be limited, specifically, a highest liquid level line 4 may be disposed in the outer tube 1, and the highest liquid level line 4 is perpendicular to the first interlayer 10 with a larger size and is tangent to the inner tube 7, so that the second working medium 5 can be prevented from contacting the wall surface of the outer tube of the inner tube at the position a in fig. 3 or contacting the wall surface of the inner tube of the outer tube at the position E, and the heat transfer effect of the second working medium in each mode is increased.
The first state of the single tube evaporator rotated to position a in fig. 3 corresponds to the best cooling effect (the largest heat-exchangeable area on the outer tube wall of the inner tube 7).
The second state of the single tube of the evaporator is realized when the evaporator is rotated to the position B, the third state of the single tube of the evaporator is realized when the evaporator is rotated to the position C, and the fourth state of the single tube of the evaporator is realized when the evaporator is rotated to the position D, wherein the area of the single tube of the evaporator on the outer tube wall of the inner tube 7 capable of supplying heat is gradually reduced, and the corresponding heat exchange amount is also gradually reduced.
When the evaporator is rotated to the E position, the single tube is in the fifth state, and the refrigerating effect is the worst (the area which can supply heat and exchange heat on the outer tube wall of the inner tube 7 is the smallest).
The evaporator single tube sixth state when rotating to the F position, the evaporator single tube seventh state when rotating to the G position, and the evaporator single tube eighth state when rotating to the H position, wherein in the sixth state to the eighth state, the area of the outer tube wall of the inner tube 7 capable of supplying heat and exchanging heat gradually decreases, and the corresponding heat exchange amount also gradually decreases.

On the basis of the above embodiments, the single tubes of the evaporator are controlled to rotate according to the preset direction and angle according to the local over-high temperature area in the refrigeration house and the current position of the single tube of the evaporator corresponding to the local over-high temperature area. The preset rotating direction and angle of the single evaporator pipe can be preset according to the current position of the single evaporator pipe.
Specifically, the local over-temperature region in the freezer may be obtained in advance by the temperature distribution detecting unit 14, such as: the infrared detector finds an area with overhigh local temperature (a warehouse door or an area with cold leakage due to poor maintenance structure of a part) and confirms the position of the area, adjusts an evaporator pipe section corresponding to the area, rotates towards the direction of enhancing refrigeration, provides proper cold energy, and ensures that goods in the area rapidly reach the state of being level with the whole warehouse temperature to realize the aim of local temperature control and refrigeration.
In addition, most of the single tubes of the evaporator can be adjusted into a low-efficiency refrigeration mode (the required cold quantity at night is small) when the refrigerator is started at night, so that the energy storage effect is achieved, the single tubes can be matched with an energy storage device of a system, the single tubes are adjusted to an enhanced refrigeration mode according to the actual condition of the required cold quantity at daytime, and finally the purpose of small and uniform temperature fluctuation of the whole day warehouse is achieved.
