2.K float about, if the expanding application scope can only be organized parallel connection more, so not only volume is big but also heat exchange weak effect, consumable material are many, take up space greatly, does not reach the purpose of energy-efficient consumption reduction, does not meet the demand for development of low-carbon economy.
Summary of the invention
For overcoming the defective of prior art; The invention provides that a kind of more energy-efficient, range of application is big, the heat exchanger of conserve space and good effect of heat exchange; Technical scheme of the present invention is: a kind of multitube coaxial-type double-tube heat exchanger; Comprise the heat exchanger main body, this main body is made up of sleeve pipe and the multi-head spiral heat exchanger tube that is installed in the sleeve pipe, and described sleeve pipe and multi-head spiral heat exchanger tube are coaxial; Described sleeve pipe is a coolant channel; Described multi-head spiral heat exchanger tube is the refrigerating medium passage, is connected with cold-producing medium gas collection distributor and liquid collector respectively at the two ends of said sleeve pipe, it is characterized in that: coaxial at least one group of screw thread heat exchanger tube and the multi-head spiral heat exchanger tube of being provided with in the inside of described multi-head spiral heat exchanger tube; On the described cold-producing medium gas collection distributor refrigerant gas air inlet pipe and refrigerating medium effuser are installed, cold-producing medium effuser and refrigerating medium are installed on the described liquid collector get into pipe.
The inside of described cold-producing medium gas collection distributor also is provided with several refrigerant gas air intake branches and several refrigerating medium flows out arm; Described refrigerant gas air intake branch is connected with corresponding sleeve pipe and screw thread heat exchanger tube respectively, and described refrigerating medium flows out arm and is connected with corresponding multi-head spiral heat exchanger tube respectively.
The inside of described liquid collector also is provided with several cold-producing mediums and flows out arm and several refrigerating medium entering arm; Described cold-producing medium flows out arm and is connected with corresponding sleeve pipe and screw thread heat exchanger tube respectively, and described refrigerating medium gets into arm and is connected with corresponding multi-head spiral heat exchanger tube respectively.
Cold-producing medium gets into from the refrigerant gas air inlet pipe on the cold-producing medium gas collection distributor, and the cold-producing medium effuser from liquid collector flows out; Refrigerating medium refrigerating medium from the liquid collector gets into pipe and gets into, and the refrigerating medium effuser from cold-producing medium gas collection distributor flows out, thereby makes cold-producing medium and refrigerating medium be the screw of adverse current shape.
The present invention has broken through the traditional structure technology bottleneck of coaxial heat exchanger; Not only make mono-layer tube become multilayer pipe, enlarged heat exchange area and range of application, and make the cold-producing medium of the heat exchanger of flowing through and refrigerating medium be the screw of adverse current shape; It is the double helix motion; Thereby the fluid that makes two media forms repeatedly circulation, produces repeatedly centrifugal force, makes that turbulent flow is stronger, heat exchange efficiency is higher.The use of two-layer efficient riffled tube has more improved the heat transfer coefficient of refrigerant side.Through applying detection, in the GB framework, its Coefficient K>=3500W/m
2.K, refrigerating medium collateral resistance H≤0.06MPa, exchange capability of heat Q>=90KW has improved 75% with existing coaxial-type heat exchanger comparison heat transfer coefficient, and exchange capability of heat has enlarged 260%, has reached the purpose of energy-conservation, synergy, consumption reduction and expanding application scope.

The specific embodiment
Referring to Fig. 2 to Fig. 5, the present invention relates to a kind of multitube coaxial-type double-tube heat exchanger,
As shown in Figures 2 and 3; Comprise the heat exchanger main body; This main body is made up of sleeve pipe 1 and eight spiral heat exchange tubes 8 that are installed in the sleeve pipe 1; Described sleeve pipe 1 and eight spiral heat exchange tubes 8 are coaxial, and described sleeve pipe 1 is a coolant channel, and described eight spiral heat exchange tubes 8 are the refrigerating medium passage; Be connected with cold-producing medium gas collection distributor 2 and liquid collector 4 respectively at the two ends of said sleeve pipe 1; It is characterized in that: coaxial at least one group of screw thread heat exchanger tube and the multi-head spiral heat exchanger tube of being provided with in the inside of described eight spiral heat exchange tubes 8, refrigerant gas air inlet pipe 3 and refrigerating medium effuser 7 are installed on the described cold-producing medium gas collection distributor 2, cold-producing medium effuser 6 is installed on the described liquid collector 4 gets into pipe 5 with refrigerating medium.
Present embodiment to be to be provided with two groups of screw thread heat exchanger tubes and bull heat exchanger tube in eight spiral heat exchange tubes 8, and referring to Fig. 3 to Fig. 5, concentric is equipped with eight spiral heat exchange tubes 8, screw thread heat exchanger tube 11, six spiral heat exchange tubes 9, screw thread heat exchanger tube 12 and four-start spiral heat exchanger tubes 10 successively in the inside of sleeve pipe 1; Wherein screw thread heat exchanger tube 11 and six spiral heat exchange tubes 9 are one group; Screw thread heat exchanger tube 12 is one group with four-start spiral heat exchanger tube 10, is connected with cold-producing medium gas collection distributor 2 and liquid collector 4 respectively at the two ends of sleeve pipe 1, referring to Fig. 3; The higher pressure refrigerant gas of coming out from compressor gets into cold-producing medium gas collection distributor 2 by refrigerant gas air inlet pipe 3; And each heat exchanger channels 15,14,13 of inflow carry out heat exchange behind the uniform distribution entering cold-producing medium air intake branch 19,20,21, and are after higher pressure refrigerant gas is condensed into liquid, as shown in Figure 4; Flow out arm 25,26,27 from cold-producing medium and flow into liquid collector 4; Get into throttling arrangement through cold-producing medium effuser 6 again after compiling, and the flow direction of refrigerating medium and cold-producing medium is opposite, thereby makes the fluid of two media form repeatedly circulation; Produce repeatedly centrifugal force, make that turbulent flow is stronger, heat exchange efficiency is higher.As shown in Figure 5, it gets into pipe 5 from refrigerating medium and flows into its passage 16,17,18 through liquid collector 4 entering pipes 28,29,30 backs, after the cold-producing medium heat exchange, flows out from refrigerating medium effuser 7 again, has accomplished heat exchanging process.
Theoretical research shows, under identical temperature difference condition, the big 15-20 of thermal discharge the when phase of cold-producing medium in condenser is dropwise condensation during than film condensation doubly.But mostly cold-producing medium condensing in condenser generally is film condensation.The application of spiral heat exchange tube; Be to realize that refrigerant gas forms dropwise condensation or membranaceous attenuation provides certain condition on geometric space; This is the high immanent cause of condensing heat-exchange efficient, and the application of screw thread heat exchanger tube 11,12 simultaneously is for good Overlay has been played in the heat transfer of cold-producing medium especially.
