Description
Technical field
The present invention relates to the device of a kind of Conduction At Low Temperature cooling system.
Background technology
Sub-cooled technology is widely used in the every field such as national economy and military project development, and medical science, electric power, section are goed deep in its application
Learn the aspects such as experiment and defence and military, nation-building is played increasing effect.Conduction At Low Temperature cooling technology is fast-developing,
Apply more and more universal.Cooled object can be cooled under conditions of without cold-producing medium by conduction cooling technology by refrigeration machine
Low temperature (such as liquid nitrogen temperature) is even below liquid helium temperature.
It is transmitted to refrigeration machine in cooling technology be connected with cooled object by conduction cooling band, absorbs the heat energy of cooled object.Conduction cooling band one
As use the fine copper of high thermal conductivity to make.The conduction cooling bar being readily bent made by conduction cooling band, then bundled by multiple conduction cooling bars,
It is connected to the cold head of cooled object and refrigeration machine.According to conduction of heat Fourier law, conduction cooling power is inversely proportional to the length of conduction cooling band,
It is directly proportional to the cross-sectional area of conduction cooling band.If cooled object quality is big, or cooled object distance cold head is farther out, needs conduction cooling
The cross-sectional area of band is bigger, thus produces enough cold power.So, the weight of conduction cooling band is the biggest.
For refrigeration machine, due to hot to the leakage of cold head in order to reduce indoor temperature end when manufacturing, therefore connect cold head and indoor temperature end
The tube wall of trachea is the thinnest, and under bigger lateral external forces, (refrigeration machine of such as SUMITOMO 415D model, it is
Big external force of running is only 20N) will deform, make refrigeration machine normally to work, the most thoroughly damage.But refrigeration machine
(refrigeration machine of such as SUMITOMO 415D model, its most maximum external force of running is more than 200 longitudinally can to bear bigger external force
N), the most in the ordinary course of things, refrigeration machine is placed perpendicular to the ground, and conduction cooling band and cold head joint are also to place perpendicular to the ground, make
The gravity obtaining conduction cooling band is parallel with cold head, i.e. the gravity of conduction cooling band only produces longitudinal pulling force to cold head.Laterally disposed for having to
The situation of cold head, typically by first conduction cooling band being well placed position, then makes it naturally droop, and finally connects conduction cooling band, so
Utilize the flexural deformation of conduction cooling band to carry himself gravity, thus do not bring laterally heavy burden to cold head.
But for the cryogenic system needing wide-angle (more than 90 degree) to rotate, its rotation will necessarily make cold head or vertically
Bear the heavy burden of conduction cooling band during face, or bear the heavy burden of conduction cooling band when parallel ground.If as it was previously stated, cooled object matter
Amount is relatively big, or distance cold head is far, then be accomplished by the conduction cooling band that quality is the biggest.Overweight conduction cooling band can be given this rotary
The cold head of cryogenic system brings infringement.
For that purpose it is necessary to fixed connecting the conduction cooling band at cold head, eliminate the cross directional stretch effect to cold head of the conduction cooling band gravity.
In order to fix conduction cooling band, a kind of method is to be fixed on cooled cryostat container by conduction cooling band, but cold head and low-temperature (low temperature) vessel is huge
The temperature difference can bring the biggest leakage heat；Another kind of method is to be fixed on cooled object by conduction cooling band, fixing device and cold head, cold
Object, in same warm area, will not bring leakage heat problem.But by the fastening of conduction cooling band with on cooled object, a problem can be brought,
It is exactly that refrigeration machine is typically anchored on low-temperature (low temperature) vessel, and cooled object is not the most anchored on low-temperature (low temperature) vessel, if cooled object occurs
Bigger skew, then cooled object can drive conduction cooling band clamp device to move together, thus also cold head is produced the biggest horizontal
Pulling force, makes cold head damage.
Summary of the invention
It is an object of the invention to overcome the shortcoming of prior art, propose a kind of cryocooler cold head flexible transverse support means.The present invention
The lateral pull suffered by Cryo Refrigerator cold head can be offset, do not bring extra big thermic load to cold head, it is ensured that refrigeration machine exists simultaneously
Can be not damaged by during cooled object generation larger displacement.
Cryocooler cold head flexible transverse support means of the present invention, is made up of conduction cooling band, nylon rope and support.Described conduction cooling band
One end is connected to cryocooler cold head, and the other end connects cooled object.Cooled object is fixed in low-temperature (low temperature) vessel.At cryocooler cold head
Lower end place a stainless support, this support casing is contained in outside conduction cooling band, does not contacts with conduction cooling band.Described support is fixed on
On cooled object.By nylon rope, support is bundled with conduction cooling band.
Nylon rope is chosen has the material that bigger rigidity, i.e. elastic modelling quantity are the least；Nylon rope should be at pulling force corresponding to 10kg mass
Under can disconnect, it is therefore desirable to select in advance the nylon rope of suitable thickness.
Support has some through holes along the circumferencial direction of conduction cooling band, through a nylon rope between every a pair adjacent through-holes, and this root Buddhist nun
Dragon rope bundles with conduction cooling band；So, multipair through hole passes many nylon ropes, enables conduction cooling band to be consolidated on multi-direction
Fixed.
When whole cryogenic system deflects in one direction, owing to the flexibility that conduction cooling band is many copper wires or copper strips is made is led
Cold parts, therefore can deform upon due to action of gravity after conduction cooling belt deflector, thus pull cold head, but when conduction cooling band colligation
After nylon rope, nylon rope absorbs the horizontal tensile stress that cold head is produced on gravity direction by conduction cooling band, makes the cold head continue
Work；When cooled object occurs bigger skew, there is bigger skew in support the most therewith, and now nylon rope disconnects, cold head not with
Support and cooled object move, and play the effect that protection cold head is the most destroyed.
