Operation principle of the invention is：
It is a kind of gas boost device based on thermal transpiration effect due to exerting gloomy compressor, when master is exerted in gloomy compressor set 2
The hot chamber 26 for exerting gloomy compressor by hot chamber heat exchanger 29 using carry (useless) hot medium more than industry maintain it is higher
Temperature, and cold chamber 25 using the gas refrigerant of low-temp low-pressure by cold chamber heat exchanger 30 when maintaining relatively low temperature, if this
When gas refrigerant molecule mean free path be not less than and exert the aperture in hole on the porous interlayer 27 of gloomy compressor and just can expire
There is the condition of thermal transpiration effect in foot, gas refrigerant just moves to temperature hot chamber 26 higher from the relatively low cold chamber 25 of temperature,
So that gas refrigeration agent molecule is assembled and pressure rising in hot chamber 26, exerting gloomy compressor plural serial stage can improve compression ratio,
Gas refrigerant is set to obtain elevated pressures, but the temperature of gas compressed refrigerant is almost unchanged, and this makes master exert gloomy compressor
Group 2 can substitute the increasing apparatus such as traditional compressor, working medium pump, and master exerts gloomy compressor set 2 and passes through preparation input pipe 1 constantly
Gas refrigerant is extracted out and boosted from vacuum tank 8, being then conveyed to cooler 4 from refrigerant efferent duct 3 is cooled down, therefore
Master exerts gloomy compressor set 2 and also acts as the effect vacuumized to vacuum tank 8, so that gas refrigerant is in system internal circulation flow.It is cold
But 4 pairs of gas refrigerants for exerting the HTHP of discharge in gloomy compressor set 2 from master of device are cooled down, by gas refrigerant
State is changed into middle temperature high pressure.The gas refrigerant of middle temperature high pressure is first carried out after being flowed into refrigerant heat exchanger 19 before throttling
Precooling in advance, entering back into throttle mechanism 5 carries out decrease temperature and pressure.From the low temperature low pressure gas refrigerant out of throttle mechanism 5
Enter into after lowering the temperature to refrigerating medium in refrigerating medium heat exchanger 6, then flowed into vacuum tank 8 by vacuum valve 12, and to refrigerating
Further cooling is made in agent, and refrigerating medium is just obtained enough colds, used with supply and demand awkward silence at a meeting.11 are exported from the tank of vacuum tank 8
After low temperature low pressure gas refrigerant out is preheated through refrigerant heat exchanger 19, system is conveyed to again by the major part of triple valve 18
Cryogen input pipe 1, fraction is conveyed to cooling medium inlet pipe 16.Cooling medium inlet pipe 16 is low temperature low pressure gas refrigerant
After being transported to the flow channel 36 of the cavity of resorption 33 of the main base station body 22 for exerting gloomy compressor set 2, then entered by each air admission hole 38
Each the cold chamber 25 for exerting gloomy compressor in gloomy compressor set 2 is exerted in each cold chamber heat exchanger 30 to master to cool down, then
This portion gas refrigerant flows to flow pass 37 from venthole 39 again, and is conveyed to through cooling medium outlet 17 and auxiliary exerts gloomy pressure
The main-inlet of the base station body of contracting unit 15, it is auxiliary exert in gloomy compressor set 15 each exert gloomy compressor by thermal transpiration effect sequentially
The relatively low gas refrigerant of the pressure discharged from cooling medium outlet 17 is risen into high pressure, so that gas refrigerant can flow back
Into the of a relatively high vacuum tank 8 of pressure, so as to realize circulating.
Of the invention to exert gloomy compressor for modularized design, construction is fairly simple, exerts the hot chamber 26 of gloomy compressor by heat
Chamber heat exchanger 29 utilizes (useless) heat more than industry to maintain temperature higher, and it directly can be combined with industrial processes,
It is (useless) hot more than industrial generation to make full use of, it is not necessary to consume too many high-grade electric energy or mechanical energy.Refrigerating medium exists
Just can be conveyed to after the cold that gas refrigerant release is absorbed in refrigerating medium heat exchanger 6 and vacuum tank 8 needs awkward silence at a meeting to be used, so that
Conventional refrigerant unit can partly be substituted for technological process and the cold needed for suitable for producing environment etc. is provided is built.It is of the invention
Simple structure, whole system movement-less part, it is not necessary to lubricating oil is reliable, and the refrigeration of whole system is higher, its refrigeration
Amount can be adjusted according to actual needs.In addition, gas refrigerant of the invention can use natural environmental-protective and chemical property is steady
Fixed gas.Gas (such as air, nitrogen) is used as refrigerant history very long, gas refrigerant and conventional refrigerants
(such as ammonia, HFCs, HCFCs) is compared, cheap, is readily available, to human body and the complete non-hazardous of environment.
The foregoing description to specific illustrative embodiment of the invention be in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explaining that certain principles of the invention and its reality should
With so that those skilled in the art can realize and using a variety of exemplaries of the invention and
A variety of selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
