Description
Technical field
The present invention relates to heat energy and power field, especially a kind of straight counter-flow heat exchanger of mixing.
Technical background
Have heat conductive wall between traditional heat exchanger high temperature fluid and the cryogen, two kinds of fluids do not mix, because the existence of the temperature difference, this class heat exchanger volume is big, and efficient is low.If allowing high temperature fluid and cryogen during the course mixes, two kinds of fluids directly can be mixed in a container so, though this way can make the volume of heat exchanger lower significantly, but lost the advantage that convection heat transfer' heat-transfer by convection brought of heat exchanger, needed bigger fluid flow just can make the temperature of mixed fluid reach requirement.If can invent the heat exchanger that the convection heat transfer' heat-transfer by convection advantage had been mixed but also had to a kind of high temperature fluid and cryogen not only, the volume of heat exchanger is reduced significantly, in the process that is cooled to purpose, can reduce the flow of cooling medium; In with the process that is heated to be purpose, can reduce the flow of heat medium.
Summary of the invention
In order to address the above problem, the technical scheme that the present invention proposes is as follows:
A kind of straight counter-flow heat exchanger of mixing, comprise mixer A and mixer B, described mixer A and described mixer B are communicated with, on described mixer A, establish high temperature fluid inlet and hot mixture outlet, on described mixer B, establish cryogen inlet and the outlet of low-temperature mixed thing, if be communicated with the counter-flowing path of described mixer A and described mixer B, on described counter-flowing path, establish the fluid pump.
Between described mixer A and described mixer B, establish at least one inter-stage mixer, described mixer A is communicated with described mixer B through each described inter-stage mixer successively, and two or more described counter-flowing paths continue mutually and are communicated with described mixer A and described mixer B through each described inter-stage mixer successively.
Described mixer A that is interconnected and the assembly of described mixer B are made as slender pipeline, near an end of described slender pipeline, establish described high temperature fluid inlet and the outlet of described hot mixture, establish described cryogen inlet and the outlet of described low-temperature mixed thing near the other end of described slender pipeline, described counter-flowing path is communicated with near the mixed zone of an end of described slender pipeline and near the mixed zone of the other end of described slender pipeline.
On described mixer A, establish outlet of cryogen phase transformation thing and/or the outlet of hot cryogen, on described mixer B, establish outlet of high temperature fluid phase transformation thing and/or the outlet of cold high temperature fluid.

Described mixer A that is interconnected and the assembly of described mixer B are made as slender pipeline, and that continues mutually on the length direction of described slender pipeline is provided with two or more described counter-flowing paths.
On one or more described inter-stage mixers, establish the fluid export mouth, to derive the fluid or the fluid phase change thing of specific concentrations or specified temp.
On non-two end regions of described slender pipeline, establish one or more fluid export mouths, to derive the fluid or the fluid phase change thing of specific concentrations or specified temp.
Principle of the present invention is after the part with the mixture of high temperature fluid and cryogen pumps system, is injected in the high temperature fluid stream of upstream (or in the higher high temperature fluid and cryogen mixture of the temperature of upstream) again, forms the mixed convection heat transfer relation; Or after the part of the mixture of high temperature fluid and cryogen pumped system, be injected in the cryogenic fluid stream of upstream (or in the lower high temperature fluid and cryogen mixture of the temperature of upstream) again, form the mixed convection heat transfer relation.The rest may be inferred, can form more multistage mixed convection heat transfer or stepless mixed convection and conduct heat.The temperature of many adjacent two mixers of the number that is meant mixer can be considered as identical mixed convection heat transfer type with the component difference to such an extent as to so-called stepless mixed convection conducts heat, perhaps in being provided with the structure of slender pipeline, can be considered as identical mixed convection heat transfer type with component to such an extent as to be provided with the temperature in two zones of a counter-flowing path connection of many counter-flowing paths.
The mixed convection that straight mixed counter-flow heat exchanger disclosed in this invention can be used between gas gas, gas-liquid or the liquid liquid conducts heat, and the mixed convection heat transfer or the mixed convection between critical fluids and the non-critical fluid that can also be used between critical fluids conduct heat.
The so-called counter-flowing path of the present invention is meant the fluid in a certain mixer is pumped into passage in the adjacent mixer that the flow direction of counter-flowing path can be pointed to high temperature fluid, also can point to cryogen; In being provided with the structure of slender pipeline, so-called counter-flowing path is meant the fluid in a certain zone of slender pipeline is pumped into adjacent area in the slender pipeline that the flow direction of counter-flowing path can be pointed to high temperature fluid, also can point to cryogen; In general, the flow direction of counter-flow duct should be opposite with main flow direction, and so-called main flow direction is meant the flow direction that is communicated with between adjacent two mixers, and in being provided with the structure of slender pipeline, so-called main flow direction is meant the flow direction in the slender pipeline.
The so-called cryogen of the present invention is meant that at the described straight heated fluid in the counter-flow heat exchanger that mixes so-called high temperature fluid is meant at the described straight fluid that is cooled in the counter-flow heat exchanger that mixes; So-called cryogen phase transformation thing is meant the product that cryogen undergoes phase transition, and is steam as the phase transformation thing of water; So-called high temperature fluid phase transformation thing is meant the product that high temperature fluid undergoes phase transition, and is water or ice as the phase transformation thing of water vapour; So-called hot cryogen is meant accepts the cryogen that the temperature behind the convection heat transfer' heat-transfer by convection uprises; So-called cold high temperature fluid is meant the high temperature fluid of accepting the temperature step-down behind the convection heat transfer' heat-transfer by convection; So-called counter-flowing path continues the fluid issuing that is meant two the adjacent counter-flowing paths with series relationship and inlet mutually through mixer or through the interconnective relation in a certain zone of slender pipeline; The assembly of so-called mixer A and mixer B is meant is arranged to an integral body with mixer A and mixer B, and then constitutes slender pipeline.
The setting of fluid export mouth of the present invention is to mix for the fluid that obtains different temperatures or different constituents from system.For example when with the liquid oxygen in the liquid oxygen storage tank during as cryogen, can be by the oxygen-containing gas that obtains high concentration that is provided with of fluid export mouth, when being necessary, this high concentration oxygen-containing gas is imported the combustion chamber of engine, can guarantee the output of engine transient high power, improve the load responding ability of engine.
Beneficial effect of the present invention is as follows:
1, the present invention is simple in structure, low cost of manufacture, reliability height.
2, the present invention had both made high temperature fluid and cryogen mix, and had kept the advantage of convection heat transfer' heat-transfer by convection again, had increased substantially the efficient of heat exchanger.
