Description
Technical field
The present invention relates to Stirling cycle refrigerator technical fields, and in particular to one kind for -160 DEG C~0 DEG C warm area this
The nonmetallic regenerator of special woods refrigeration machine and the manufacturing method of nonmetallic regenerator.
Background technique
The operation temperature area of general sterlin refrigerator is near 77K (- 196 DEG C), with low-temperature biological refrigerator, cold chain at present
Increase of the refrigerator to sterlin refrigerator demand, high-temperature region (- 160 DEG C~0 DEG C) sterlin refrigerator are increasingly becoming research hotspot,
Its requirement to regenerator is also different from 77K warm area refrigeration machine.
Regenerator is the place of sterlin refrigerator heat to power output.After gas working medium passes through compressor compresses, changed in hot end
Hot device part carries out cooling (being generally cooled near 30 DEG C -40 DEG C), carries out heat exchange subsequently into regenerator.Gas passes through
The temperature end of regenerator, gradually flows to low-temperature end, constantly exchanges heat with regenerator in flow process, when gas reaches backheat
When the low-temperature end of device, the temperature of gas is lower, expands subsequently into expansion chamber and obtains refrigeration effect, and temperature further decreases.
Therefore regenerator needs are accomplished to realize in shorter length the biggish temperature difference (typically changing to -160 DEG C from 30 DEG C), need
Wanting regenerator, thermal conductivity is lower in the axial direction, and thermal conductivity is higher in radial directions.It needs to guarantee in regenerator
Enough filler and gas in a relatively short period of time sufficiently exchange heat, and regenerator needs to have biggish heat exchanger area, and water conservancy diameter
It is far smaller than the heat penetration of working medium.Furthermore the thermal capacitance of regenerator material is greater than the thermal capacitance of working medium, can rise in this way
It is acted on to accumulation of heat.
Existing regenerator generally uses metal regenerator or aramid fibre regenerator, guarantees that its thermal capacitance is greater than work
Matter thermal capacitance.In order to guarantee that its lesser water conservancy radius and biggish heat exchange area, metal regenerator need to have very high mesh
Number, so that metal regenerator is on the high side.Aramid fibre regenerator price is lower, but its weaving manner, filling
Mode etc. does not ensure that the consistency of the string diameter of regenerator and the consistency of regenerator entirety porosity.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, -160 DEG C~0 DEG C temperature is used for the object of the present invention is to provide a kind of
The nonmetallic regenerator of area's sterlin refrigerator and the manufacturing method of nonmetallic regenerator efficiently solve existing regenerator and exist
Manufacture difficulty is big, regenerator porosity consistency is poor and cost is excessively high problem.
In order to achieve the above objectives, the technical solution adopted by the present invention to solve the technical problems is:
A kind of nonmetallic regenerator for -160 DEG C~0 DEG C warm area sterlin refrigerator, including sleeve, the interior stacking of sleeve
There is multi-disc felt, the felt is formed by non-metallic filaments longitude and latitude uniform interleaving, and the string diameter of non-metallic filaments is 8-100 μm.

The consistency of whole porosity.
Further, from hot end to cold end, the quantity that felt is laminated in each regenerator unit in unit length successively increases.
Since from the hot end of nonmetallic regenerator to cold end, refrigeration machine working medium is different in the dynamic viscosity of different temperature zones,
The dissipation of stickiness caused by hot end can be more than cold end in unistage type regenerator.Using the above preferred scheme, in hot end regenerator list
The felt elasticity of member is relatively loose, and porosity is relatively large, i.e., for entire hole of the nonmetallic regenerator from hot end to cold end
Gap rate gradually becomes smaller, and spreads refrigeration machine working medium in entire nonmetallic regenerator more steady, reduces the glutinous of entire regenerator
Property dissipate, while nonmetallic regenerator cold end has biggish heat dissipation area, can more sufficiently exchange heat and improve effectiveness of regenerator.
A kind of manufacturing method of nonmetallic regenerator, comprising the following steps:
Step 1, wire drawing: according to nonmetallic regenerator hydraulic diameter and heat penetration, drawing string diameter is 8-100 μm non-
Filament；
Step 2, felt: the felt for using plain weave mode to weave porosity as 60%-94% is woven；
Step 3, nonmetallic regenerator assembling: felt is loaded in regenerator frame, by the filling the piece number for changing felt
To adjust the porosity of nonmetallic regenerator.
Using the above preferred scheme, the felt of suitable thickness and porosity is woven into using the nonmetallic materials of suitable string diameter
Piece controls the porosity of nonmetallic regenerator entirety by adjusting felt quantity filling elasticity when loading regenerator,
It can guarantee the consistency of the whole porosity of nonmetallic regenerator and convenient for control, guarantee the warm area sterlin refrigerator
Performance and efficiency；Reduce the cost of refrigeration machine.
Further, the nonmetallic regenerator is composed of multiple regenerator units, is first manufactured back by step 3 method
Hot device unit finally combines each regenerator unit, and from hot end to cold end, felt is laminated in each regenerator unit in unit length
The quantity of piece successively increases.
Using the above preferred scheme, relatively loose in the felt elasticity of hot end regenerator unit, porosity is relatively
Greatly, i.e., entire porosity of the nonmetallic regenerator from hot end to cold end is gradually become smaller, effectively reduces refrigeration machine working medium and exists
Stickiness brought by high temperature section dynamic viscosity height dissipates, and spreads refrigeration machine working medium in entire nonmetallic regenerator more flat
Surely, the stickiness for reducing entire regenerator dissipates, while nonmetallic regenerator cold end has biggish heat dissipation area, can more sufficiently exchange heat
And improve effectiveness of regenerator.
