Abstract
This patent discloses a kind of vascular refrigerator multilayer vascular.Its structure is coaxially arranged multilayer vascular, and multilayer vascular arrangement is by vessel segmentation into several parallel gas channels.Endovascular working medium make it that endovascular velocity field and thermo parameters method state are more uniform through multilayer vascular arrangement；So as to suppress the Complex Flows such as endovascular turbulent flow, Secondary Flow, direct current；Vascular runner draw ratio is added in limited system length, adds cooling system efficiency；Improve vascular cold end quality stream and pressure wave phase relation to a certain degree, increase refrigerating capacity, improve efficiency of refrigerator.
Description
Technical field
This patent is related to a kind of vascular, and in particular to a kind of structure and design method of vascular refrigerator multilayer vascular.
Background technology
As infrared detector and low-temperature superconducting equipment etc. are increasing to the demand of cold, develop High cooling power vascular system
Cold it is very necessary.But with the raising of cold, vascular certainly will become thicker and limitation is truly had in length, and this causes vascular
Draw ratio diminishes, and the Complex Flows such as endovascular turbulent flow, Secondary Flow, direct current degree aggravates, and have impact on pulse tube refrigeration mechanism cold
Energy.
The multilayer vascular part crucial as vascular refrigerator.It will realize following several respects major function：
1) vessel segmentation is added into vascular runner field footpath into several parallel gas channels in limited system length
Than.
2) efficiently sound work(transmission, by suppressing the Complex Flows such as endovascular turbulent flow, Secondary Flow, direct current, makes endovascular
Working medium make it that endovascular velocity field and thermo parameters method state are more uniform through multilayer vascular arrangement；Reduce vascular both ends sound work(
Transmission loss.
The content of the invention
The purpose of this patent is that this patent is related to a kind of structure of vascular refrigerator multilayer vascular, solves pulse tube refrigeration
In machine design with cold increase caused by complex flow improves, vascular draw ratio reduces, sound work(efficiency of transmission is low etc. asks
Topic.
For the above-mentioned purpose, a kind of structure and design method of vascular refrigerator multilayer vascular, its structure is by outermost layer arteries and veins
Pipe 3, internal multilayer vascular 2, support 1 form.Support 1 and internal multilayer vascular 2, outermost layer vascular 3 are by same material stainless steel
Manufacture.There is mounting groove on support 1, be connected with internal multilayer vascular 2, outermost layer vascular 3.Support 1 is by mounting groove by
Portion's multilayer vascular 2 is positioned inside outermost layer vascular 3, and both ends are concordant between outermost layer vascular 3 and internal multilayer vascular 2, internal
Multilayer vascular (2) and outermost layer vascular (3) keep arranged concentric.
First, outer layer vessel thickness W is determined according to processing technology and operating mode；
Secondly, internal multilayer vascular number of plies i：
Wherein：D1For outer layer vascular internal diameter；L is vessel length；A is the vascular draw ratio needed.
Finally, internal multilayer vascular internal diameter D is calculated according to demandi：
D1 2-D2 2=D2 2-D3 2=...=Di-1 2-Di 2=Di 2 (2)
The thickness of internal vessels considers that the requirement of processing technology is controlled in 0.1mm-0.2mm.
The advantages of this patent
1) vessel segmentation is added into vascular runner field footpath into several parallel gas channels in limited system length
Than.
2) efficiently sound work(transmission, by suppressing the Complex Flows such as endovascular turbulent flow, Secondary Flow, direct current, makes endovascular
Working medium make it that endovascular velocity field and thermo parameters method state are more uniform through multilayer vascular arrangement；Reduce vascular both ends sound work(
Transmission loss.
Above-mentioned advantage will greatly promote the raising of vascular refrigerator vascular performance, the lifting tool for refrigeration machine overall performance
There is very important meaning.
Brief description of the drawings
Fig. 1 is multilayer vascular refrigerator structural representation；
Fig. 2 is multilayer vascular refrigerator multilayer vascular structure sectional view；
Fig. 3 is multilayer vascular refrigerator vascular stent structure top view；
Wherein：1 it is support, 2 be internal vessels, 3 is outermost layer vascular.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is done to specific implementation of the patent mode and further described in detail.In this patent
Description in, it is necessary to explanation, the term " finger such as " center ", " radial direction ", " on ", " under ", " interior ", " outer ", " vertical ", " level "
Show that orientation or position relationship are based on position relationship shown in accompanying drawing, be for only for ease of description this patent and simplify description, without
It is instruction or implies particular orientation that signified device or element must have, with specific azimuth configuration and operation, therefore not
It is understood that as the limitation to this patent.In addition term " first ", " second " are only used for describing purpose, and it is not intended that instruction or
Imply relative importance.In addition, in the description of this patent unless otherwise indicated, " multiple " be meant that two or two with
On.
As shown in figure 1, the structure and design method of a kind of vascular refrigerator multilayer vascular invented, using stainless steel
Material manufacture, outer layer vascular external diameter 0.3mm, internal diameter 20mm, length 73mm；To make draw ratio be more than 5, according to formula (1), obtain
The internal vessels number of plies is 1, is 14mm, wall thickness 0.15mm according to calculating to internal vessels internal diameter.
So as to form the multilayer vascular structure for vascular refrigerator.
