Description
Technical field
The present invention relates to a kind of built in film type bidirection air inlet structure vessel refrigerator.
Background technology
In the vascular refrigerator by the driven compressor of simple harmonic motion, it is feature that hydraulic fluid flows with alternation.When vascular refrigerator is in bidirection air intake pattern when work, because the asymmetry of valve flow coefficient, flow in the breathing action and to flow out the tolerance of bidirection air intake valve incomplete same, in the closed-loop path of the vascular of flowing through, regenerator, can cause direct current.Studies show that, only account for the very small scale of alternating masses stream even direct current flows, its caused parasitic hot-fluid but is in the same order of magnitude with the theoretical refrigerating capacity of vascular refrigerator.These flow to cold junction from the hot junction additional hot-fluid has not only increased the load of cool end heat exchanger, has reduced the performance of vascular refrigerator, but also is to cause the unsettled major reason of vascular refrigerator cryogenic temperature.
Because bidirectional air intake structure has unrivaled phase modulation of other structure and amplitude modulation dual-use function, should be as far as possible on the basis that keeps bidirectional air intake structure in order to obtain good refrigeration performance, adopt the control of additional structure realization, with phase modulation, the amplitude modulation advantage of performance bidirectional air intake structure to direct current.In order to obtain good performance, utilize the asymmetrical type of breathing action valve flow coefficient usually, adopt the double-valve bidirectional air intake structure of adverse current parallel connection or arranged in series, direct current is flowed suppress, with further raising vascular refrigerator performance.The common drawback of these methods is: they depend on valve performance by force to the inhibition ability of direct current, must carry out performance adjustment to every refrigeration machine, need valve opening is readjusted for different operating modes, and the refrigeration machine stability is poor.In addition, the refrigeration performance repdocutbility is also very poor.The existence of these problems is extremely unfavorable for the practicability of two-way air inlet pulsing pipe refrigerator.In order to realize its large-scale commercial application, must develop and more simply suppress means, the dual simplicity that realizes the vascular refrigerator structure and regulate.
Summary of the invention
Purpose of the present invention is intended at above-mentioned the deficiencies in the prior art, and a kind of built in film type bidirection air inlet structure vessel refrigerator that can overcome poor stability is provided.
Realize the built in film type bidirection air inlet structure vessel refrigerator of above-mentioned purpose, comprise that air reservoir, this air reservoir are connected in the input of little ports valve, the output of little ports valve is connected in aperture valve output formation closed-loop path by the bidirection air intake valve after being connected in vascular hot-side heat exchanger, vascular, vascular cold end heat exchanger successively more again after cold head is connected in regenerator cool end heat exchanger, regenerator, regenerator hot end heat exchanger successively, it is characterized in that, also be included in the elastomeric isolation film is set in the vascular.The direct current that this film not only can stop bidirectional air intake structure to bring out flows, and participates in the transmission of merit stream in the vascular with air-flow, thereby improves the refrigeration machine performance.Compare with the direct current inhibition method of present employing, have outstanding advantages such as effect is obvious, good stability, can overcome the complex structure that present direct current inhibition method exists well, poor stability, be subjected to operating mode to influence defectives such as big, help promoting the large-scale commercial applications application of two-way air inlet pulsing pipe refrigerator.

The specific embodiment
As shown in Figure 1, built in film type bidirection air inlet structure vessel refrigerator of the present invention comprises bidirection air intake valve 1, air reservoir 2, aperture valve 3, vascular hot-side heat exchanger 4, vascular 6, vascular cold end heat exchanger 7, cold head 8, regenerator cool end heat exchanger 9, regenerator 10, regenerator hot end heat exchanger 11; It is characterized in that said vascular refrigerator is provided with elastomeric isolation film (5) in vascular.
In vascular refrigerator, there is closed circuit as long as we know, just might forms direct current.The condition that provides is provided the direct current that is introduced as of second intake valve in the two-way air inlet pulsing pipe refrigerator.And in the vascular refrigerators such as pinhole type, owing to there is not the loop of the vascular of flowing through, regenerator, the total direct current pressure that forms in the flow resistive element such as vascular, heat exchanger falls and just equals to eliminate the required pressure drop of direct current, can not produce direct current.Same closed-loop path by employing elastomeric isolation film cut-out two-way air inlet pulsing pipe refrigerator also just can be blocked the approach that direct current produces effectively, avoids the generation of direct current.Meanwhile,, when stoping air current flow, the transmission of merit stream in the vascular be can participate in together, required pressure wave of good refrigeration performance and mass flow phase angle obtained with air-flow because the elastomeric isolation film has better elastic.And the phase modulation and the merit stream that can not influence refrigeration machine because of the existence of elastic membrane transmit performance, thereby are realizing obtaining higher refrigeration performance on the D.C. suppressed basis.
The position of relevant elastic membrane can be tried to achieve by variable mass system thermodynamics and phase modulation theory.In order to realize the D.C. suppressed while, prevent the laminar flow characteristics of elastomeric isolation film destroy gas piston, usually it is arranged in about 1/4 place from the vascular hot junction, as shown in Figure 1.In compression process, because the pressure reduction that the diaphragm both sides exist makes it at the end be stretched to the vascular hot junction in compression, expanding at the end then is stretched to the vascular middle part, and its view is respectively shown in Fig. 2 and 3.
