Description
One, technical field
The present invention relates to a kind of adsorption phase-regulating vascular refrigerator, belong to vascular refrigerator.
Two, background technology
Vascular refrigerator has simple in structure, little, the high outstanding advantage of reliability of vibration owing to moving component under the no low temperature, is expected to be used widely at high-technology fields such as information, superconduction and spaces, and be the research focus of Cryo Refrigerator all the time.By alternation fluid channel theory as can be known, obtain good refrigeration performance, need to adopt various phase modulating mechanisms, make the pressure wave and the mass flow homophase of its cold junction in order to make vascular refrigerator.Through the effort of various countries scholar recent two decades, the vascular refrigerator of multiple structures such as aperture air reservoir type, bidirection air intake type and inertia cast has successively been proposed, the vascular refrigerator performance is constantly improved, on some performance indications even surmounted traditional Cryo Refrigerator.
Yet, in the vascular refrigerator of above-mentioned all versions, in order to obtain the required phase-shift phase of best refrigeration performance, the air reservoir important component part that all is absolutely necessary.In actual applications, the volume of air reservoir is often very huge, the 5-10 that is about all the other all part void volumes of pulse pipe refrigeration machine system doubly, the existence of air reservoir has not only increased the physical dimension and the weight of system greatly, also increase the stress loading of refrigeration machine when the motion occasion is used, brought very big obstacle in the application of technical fields such as space for refrigeration machine.Meanwhile, because the existence of air reservoir void volume in order to reach the performance identical with traditional Cryo Refrigerator, needs more gas and participates in circulation, energy consumption is also very high.Therefore,, make it obtain large-scale commercial applications and use, very be necessary existing air reservoir phase modulation type vascular refrigerator is improved or develops vascular refrigerator based on other pm mode in order further to optimize vascular refrigerator structure and performance.
Three, summary of the invention
Purpose of the present invention is intended at above-mentioned the deficiencies in the prior art, provides that a kind of compact conformation, phase modulation ability are strong, good stability and the low adsorption phase-regulating vascular refrigerator of energy consumption.
Realize the adsorption phase-regulating vascular refrigerator of above-mentioned purpose, comprise bidirection air intake valve, vascular hot-side heat exchanger, vascular, vascular cold end heat exchanger, cold head, regenerator cool end heat exchanger, regenerator, regenerator hot end heat exchanger; It is characterized in that also being included in said vascular hot-side heat exchanger outer end and be provided with the absorber that is connected with this vascular hot-side heat exchanger, utilize good capacitive reactance of absorber and induction reactance effect, replace air reservoir and inertia tube in the conventional vascular refrigeration machine, thereby reach the required optimal phase shift amount of refrigeration machine work.
Compare with air reservoir, the inertia cast vascular refrigerator of present employing, outstanding advantage such as this system has that compact conformation, phase modulation ability are strong, good stability and energy consumption are low, the large-scale commercial applications that helps to promote vascular refrigerator is used.
Four, description of drawings
Fig. 1 is the adsorption phase-regulating vascular refrigerator structural representation;
Above-mentioned number in the figure title: 1, bidirection air intake valve, 2, absorber, 3, vascular hot-side heat exchanger, 4, vascular, 5, vascular cold end heat exchanger, 6, cold head, 7, the regenerator cool end heat exchanger, 8, regenerator, 9, the regenerator hot end heat exchanger.
Five, the specific embodiment
As shown in Figure 1, adsorption phase-regulating vascular refrigerator of the present invention comprises bidirection air intake valve 1, vascular hot-side heat exchanger 3, vascular 4, vascular cold end heat exchanger 5, cold head 6, regenerator cool end heat exchanger 7, regenerator 8, regenerator hot end heat exchanger 9; Wherein the hot junction of vascular 4 is connected in vascular hot-side heat exchanger 3, cold junction is connected in vascular cold end heat exchanger 5; The hot junction of regenerator 8 is connected in regenerator hot end heat exchanger 9, cold junction is connected in regenerator cool end heat exchanger 7; Vascular cold end heat exchanger 5 links to each other by cold head 6 with regenerator cool end heat exchanger 7; Vascular hot-side heat exchanger 3 links to each other by bidirection air intake valve 1 with regenerator hot end heat exchanger 9; It is characterized in that also being included in said vascular hot-side heat exchanger 3 outer ends and be provided with the absorber 2 that is connected with this vascular hot-side heat exchanger 3.
We know that the adsorbent in the absorber is made up of porous media, have very strong adsorption effect, by adsorption theory as can be known, the size of adsorbents adsorb ability is relevant with operating temperature and pressure, under the identical situation of temperature, adsorption capacity increases with the increase of pressure.In vascular refrigerator, it is feature that working fluid flows with alternation, is therefore expanding and compression stage, and adsorbent Working medium gas amount is different.At compression stage, along with the rising of gas pressure, adsorbent can constantly adsorb the Working medium gas that comes from vascular in the absorber, and the reduction along with the vascular internal pressure in the expansion stage, adsorbent then can discharge its Working medium gas in compression stage absorption, makes it enter vascular and participates in kind of refrigeration cycle.The effect of above-mentioned work characteristics and air reservoir is identical, as seen, and by the phase modulation function that the absorber that is communicated with it can be realized air reservoir is set in the vascular hot-side heat exchanger outer end.Meanwhile, different with simple air reservoir phase modulation is, owing to have a large amount of gases hole in the adsorbent, and the gas passage aisle that contact forms between the adsorbent, make gas when flowing through absorber, have bigger inertia resistance, play the effect of inertia tube, thereby further improve the phase-shift phase in vascular hot junction.Based on above-mentioned analysis as can be known, absorber has good capacitive reactance and induction reactance effect, the phase shift function of air reservoir and inertia tube can be integrated in one, and realizes the required optimal phase shift of refrigeration machine work.In actual applications, because capacitive reactance, the induction reactance effect of absorber are relevant with multiple factors such as adsorbent kind, working medium rerum natura, refrigeration machine physical dimension and running parameters, should select suitable adsorbent and particle diameter thereof for use according to different situations.
Compare with air reservoir, the inertia cast vascular refrigerator of present employing, because absorber can play simultaneously air reservoir and be used to The property pipe function, the phase modulation ability is more powerful, adopts the absorber of small volume can realize required phase-shift phase, not only Make refrigeration machine machine system structure more compact, meanwhile, participating in the required Working medium gas amount of kind of refrigeration cycle also can be corresponding Reduce, thereby reduce the refrigerator operation energy consumption. In addition, owing to be filled with adsorbent in the absorber, structural strength is than simple The air reservoir of full gas strengthens greatly, and affected by the external motion state of absorber littler for adsorption effect in addition, in the space, army The non-quiescent operation occasion such as thing can obtain more stable refrigeration performance.
