Abstract
The utility model discloses a varying-pressure air holder vessel refrigeration machine, which in turn comprises a compressor, a heat regenerator, a cold end heat exchanger, a vessel, a hot end heat exchanger, a small hole and an air holder. A communicating pipe is arranged between an outlet of the compressor and the air holder, and a varying-pressure intake valve is arranged on the communicating pipe. A communicating pipe is arranged between the outlet of the compressor and an outlet of the hot end heat exchanger, and a second intake valve is arranged on the communicating pipe. The utility model draws the advantages of an eyelet vessel refrigeration machine and a pipe expander, and the pressure in the air holder can be changed through the varying-pressure intake valve and the second intake valve, so as to cause the ideal refrigerating efficiency of the utility model to achieve 100%.
Description
The utility model relates to vascular refrigerator, relates in particular to transformation air reservoir vascular refrigerator.
Vascular refrigerator is simple in structure, and is reliable, do not have the cold junction moving-member, and obtained breakthrough raising recent years on refrigeration performance, caused the common concern of cryogenic engineering circle.The major defect of vascular refrigerator is that theoretical efficiency is lower, thereby has limited applying of it.
There is valve type vascular refrigerator different types of machines successively to occur, pinhole type, check valve type, four valve types, tube swelling type etc. are arranged.The pinhole type vascular refrigerator has two courses of work to have irreversible loss, and first high pressure valve is opened, and gases at high pressure enter the adiabatic gas replenishment process of vascular; It two is to open the adiabatic exhaust process of low-pressure gas when low pressure valve.The course of work of check valve vascular refrigerator is similar to pinhole type, can realize that by careful valve regulated gases at high pressure enter the vascular cold junction for four valve type vascular refrigerators, and do not have irreversible loss, but there is irreversible loss in gases at high pressure from the hot junction enters the process of vascular (at this moment the vascular for low-pressure gas).The tube swelling machine is developed by four valve type vascular refrigerators, it adopts (or a plurality of) air reservoir more than two, fill respectively with high pressure and low pressure (or several intermediate pressures) and make the breathing action in vascular cold junction and hot junction all not have irreversible loss, thereby make desirable refrigerating efficiency reach 100%.But, make the structure of system become complicated, the control difficulty owing to adopted (at least two) air reservoir more than two.
The purpose of this utility model provides a kind of transformation air reservoir vascular refrigerator.
In order to achieve the above object, the utility model is taked following measures: transformation air reservoir vascular refrigerator comprises compressor, regenerator, cool end heat exchanger, vascular, hot end heat exchanger, aperture, air reservoir successively.Be provided with communicating pipe between compressor outlet and the air reservoir, on communicating pipe, be provided with the transformation intake valve.
The utility model has the advantages that: it has drawn the advantage of pinhole type vascular refrigerator and tube swelling machine.Pressure in the pinhole type vascular refrigerator air reservoir generally fluctuates between average pressure, and transformation air reservoir vascular refrigerator is under the intake and exhaust time sequence control, by transformation intake valve and second intake valve pressure in the sequence change air reservoir on request, thereby make its desirable refrigerating efficiency reach 100%.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is an I type transformation air reservoir vascular refrigerator structural representation;
Fig. 2 is an II type transformation air reservoir vascular refrigerator structural representation.
Transformation air reservoir vascular refrigerator comprises compressor 1 successively, regenerator 2, cool end heat exchanger 3, vascular 4, hot end heat exchanger 5, aperture 6, air reservoir 8.Between compressor outlet and air reservoir, be provided with communicating pipe, on communicating pipe, be provided with transformation intake valve 7.Be provided with communicating pipe between compressor outlet and the hot end heat exchanger outlet, on communicating pipe, be provided with second intake valve 9.
