Description
Technical field
Patent of the present invention is that a kind of refrigerating circulatory device relates to the use of approximate constant entropy of the gas under the conditions of supersonic flows
Swell refrigeration characteristic.
Background technology
In current all kinds of refrigeration systems, throttling cooling is realized using expanding machine or J-T valves more than throttle part, there is throttling
Loss is big, the low problem of refrigerating efficiency.Under the identical pressure loss, there is approximate constant entropy expansion in supersonic nozzle because it is internal
Flowing can realize temperature drop higher, produce bigger heat transfer temperature difference, can greatly improve the heat exchange efficiency of evaporator.
The approximate constant entropy expansion refrigeration characteristic of gas under the conditions of supersonic flows is that one kind is related to gas pressure energy, interior energy, moves
The Refrigeration Technique that can mutually change, the efficiency than current conventional temperature drop equipment J-T valves, expanding machine is much higher.The pass of the technology
Key member is supersonic nozzle (Rafael nozzle), and its operation principle is：With expansion of the gas in jet pipe, air-flow occurs near
Like isentropic expansion process, air velocity gradually increases, and at the same time gas temperature and pressure drastically decline can realize what is reduced
Gas flow temperature (minimum reachable -80 DEG C~-120 DEG C).In the process, it is possible to use the ultralow temperature that gas is produced is realized and the external world
Heat exchange.
This is a kind of brand-new Refrigeration Technique, and refrigerant can obtain lower temperature, and heat transfer temperature difference is big, refrigerating efficiency
Height, can be used for the larger occasion of the refrigeration capacity requirements such as large cold storage, natural gas liquefaction.

The supersonic speed cooling cycle system that the present embodiment is provided carries out concretely comprising the following steps for kind of refrigeration cycle：
The refrigerant (air or nitrogen) that will be provided with certain pressure continuously flows into arrival manifold 2, be then tapped off into
Enter multiple supersonic nozzles 3, refrigerant occurs approximate constant entropy expansion in jet pipe, and air velocity is continuously increased, and gas flow temperature is not
It is disconnected to reduce, it is reduced to minimum (minimum reachable -80 DEG C~-120 DEG C) in outside nozzle temperature, subsequent low-temperature refrigerant enters evaporation
Device 7, heat exchange is realized with the material that evaporator 7 is flowed into by high temperature inlet 9 by heat-transfer pipe 12 and fin 13.Walked more than
Suddenly, low-temperature refrigerant absorbs amount of heat and heats up and leave evaporator 7, into condenser 4 with flowed into by low-temperature inlet 10 it is cold
The material of condenser 4 realizes heat exchange by heat-transfer pipe and fin, and condenser 4 is flowed out eventually through hot outlet 6, is entered by pipeline
Enter fluid reservoir 11.Heat-transfer pipe is made by the splendid alloy of heat-transfer effect.Fin on heat-transfer pipe increases heat-conducting area and carries
High-heat conductive efficency.
Present embodiment is the exemplary illustration to this patent and limits its protection domain those skilled in the art also
Its part can be changed as long as no beyond the Spirit Essence of this patent all in the protection domain of this patent.
