Embodiment 1

[0027] In the related technology, in the process of cleaning the cold trap, the cold trap is first taken out of the liquid nitrogen, and then the cold trap is heated by a heating device, for example, the temperature of the heat gun is set to 100 degrees and placed on a certain part (such as a bench, etc.) Blow the air outlet to the cold trap, because the wind blown by the heat gun is not concentrated in the cold trap, there will always be a certain amount of air blowing to the surrounding air to exchange heat with the surrounding air, greatly Reduced heating efficiency of the cold trap.

[0028] According to an embodiment of the present invention, a liquid nitrogen cold trap is provided, figure 1 It is a schematic structural diagram of a liquid nitrogen cold trap provided according to an embodiment of the present invention, such as figure 1 As shown, the liquid nitrogen cold trap 10 is integrated with a cold trap device 12, and the cold trap device 12 includes: a hollow conta...

Embodiment 2

[0043] According to an embodiment of the present invention, a method for clearing a liquid nitrogen cold trap is also provided, figure 2 It is a flowchart of a method for clearing a liquid nitrogen cold trap according to an embodiment of the present invention, wherein the liquid nitrogen cold trap is integrated with a cooling trap device, and the cooling trap device includes: a hollow container and a heater, such as figure 2 As shown, the process includes the following steps:

[0044] Step S202, placing the liquid nitrogen cold trap in a hollow container;

[0045] Step S204, using a heater to blow hot air into the hollow container in which the liquid nitrogen cold trap is placed, and gathering the hot air through the hollow container to heat the liquid nitrogen cold trap.

[0046] In the embodiment of the present invention, the method of placing the liquid nitrogen cold trap in a hollow container is adopted, and the heater blows hot air into the hollow container where the l...

Abstract

The invention discloses a liquid nitrogen cold trap, a clear liquid nitrogen cold trap method, a dilution refrigerator and a quantum computer. According to the liquid nitrogen cold trap, the liquid nitrogen cold trap is integrated with a cold trap cleaning device, the cold trap cleaning device comprises a hollow container and a heater, and the hollow container is used for containing the liquid nitrogen cold trap; and the heater is used for blowing hot air into the hollow container in which the liquid nitrogen cold trap is placed, and the hot air is gathered through the hollow container to heat the liquid nitrogen cold trap. The technical problem that in the related technology, in the cold trap cleaning process, the cold trap needs to be continuously heated, and consequently the efficiency of cold trap cleaning is low is solved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a liquid nitrogen cold trap, a clear liquid nitrogen cold trap method, a dilution refrigerator and a quantum computer. Background technique [0002] For the dilution refrigerator, the mixture of pure He3 and He4 flows in the dilution unit, so before entering the dilution unit, it is necessary to use a liquid nitrogen cold trap to condense the gas with a condensation temperature above 77K, such as water vapor, etc. In the liquid nitrogen cold trap, it plays the role of filtering dirty gas, preventing dirty gas from entering the dilution unit and causing blockage of components such as flow resistance, which ultimately affects refrigeration. [0003] As the number of gas cycles increases, the liquid nitrogen cold trap will condense a lot of dirty gas after a long time. If the dirty gas is not removed in time, it will cause the liquid nitrogen cold trap to be blocked. The liquid nitrogen co...
