Embodiment 1

[0038] see figure 1 , this embodiment provides a heat insulating support device in a low temperature application environment, comprising an outer pipe 1 and a support 2 for supporting an inner part 3, wherein the inner part 3 is placed in the outer pipe 1, and the outer pipe 1 Both the outer pipe 1 and the inner part 3 have a circular tube structure, and the outer pipe 1 and the inner part 3 are not limited to the circular tube structure, and can also be designed to be oval, triangular, rectangular or other polygonal tubular structures in cross-section according to actual needs.

[0039] The inner part 3 is isolated from the outer pipe 1 .

[0040] The support member 2 includes a support bar 21, and the two ends of the support bar 21 along its heat conduction path are respectively connected to the external pipe 1 and the inner part 3 by means of welding or bonding, or the support bar 21 satisfies the support for the inner part 3, In the case that the inner part 3 is isolated ...

Embodiment 2

[0056] see Figure 6 and Figure 7 , this embodiment is based on the heat-insulating support device described in Embodiment 1. The difference is that the support bar 21 described in this embodiment has a linear structure. The connection of the inner connectors 23, the two coaxially arranged outer connectors 22 and the inner connectors 23 are arranged at intervals along the axis, and the support strips of each linear structure are arranged along the middle of the outer connectors 22 or the inner connectors 23. The axes are evenly arranged, so that Figure 7 The supporting member 2 shown has a simple structure, is convenient to prepare, has good supporting strength, and can effectively reduce heat conduction and heat leakage between the external pipe 1 and the internal part 2 .

[0057] Based on the above structure, the supporting bar 21, the outer connecting piece 22 and the inner connecting piece 23 can be integrally cut out on a plane with a thin plate, that is, the support...

Embodiment 3

[0059] see Figure 8 and Figure 9 , this embodiment is based on the heat insulating support device described in Embodiment 1, the difference is that the support bar 21 described in this embodiment has a linear structure, and the outer connector 22 and the inner connector 23 are along the same central axis It is a planar ring structure arranged in parallel.

[0060] Compared with the support shown in Example 2, this kind of support has a similar structure, and also has better support strength. There is a line contact between the planar ring structure and the outer pipe 1 or the inner part 3, and the contact area is smaller. The heat conduction between the outer channel 1 and the inner part 2 can be effectively reduced.

[0061] For the supporting member 2 in the above embodiments 1-3, the supporting bar 21 and the outer connecting member 22 and / or the inner connecting member 23 can be integrally formed by 3D printing, which is convenient for preparation.

[0062] At the sam...

Abstract

The invention relates to the technical field of refrigeration and low-temperature application, and provides an insulation supporting device. The insulation supporting device comprises an external pipeline and a supporting part used for supporting an inner part, wherein the inner part is arranged in the external pipeline; the supporting part comprises a supporting strip; the two ends of the supporting strip along the heat conduction path of the supporting strip are respectively connected with the external pipeline and the internal part, or one end of the supporting strip along the heat conduction path of the supporting strip is connected with the external pipeline or the internal part; and the length of the heat conduction path of the supporting strip is greater than the distance between the external pipeline and the inner part. The insulation supporting device has the advantages of being simple in structure and convenient to manufacture; and the heat transfer resistance between the external pipeline and the internal part is increased while the support of the internal part is satisfied and the mechanical isolation between the internal part and the external pipeline is guaranteed, the long-distance transmission of low-temperature cold or low-temperature fluid through the internal part are conveniently achieved, and the loss of the low-temperature cold in the transmission processis reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration and low temperature applications, in particular to a thermal insulation support device. Background technique [0002] With the development of science and technology, refrigeration and cryogenic application technologies have been widely used and developed in many fields such as superconducting electronics, cryogenic optics, aerospace, and biomedicine. In many application environments, low-temperature cooling capacity or low-temperature fluid needs to be transmitted long-distance through the vacuum insulation channel. Since there is a very large temperature difference between the low-temperature part and the external environment, the low-temperature part in the vacuum insulation channel needs to be fixed and supported by an insulating support device. , in order to reduce the heat conduction and heat leakage between the external environment and the low-temperature part, so as to ensure the smoo...
