Description
Technical field
The utility model relates to a kind of two sleeve pipes of air-conditioning.
Background technology
Using the heat exchanger of various structures as air conditioner for vehicles, wherein, widely used mode has the heat exchanger of double-tube structure.Conventionally double-tube structure that heat exchanger uses, as disclosed technology in the patent publication No. Chinese patent literature that is 103162470A, two sleeve pipes everywhere interface connect respectively condenser liquid outlet, evaporimeter inlet, evaporimeter gas outlet, compressor return air mouth, wherein between condenser liquid outlet, evaporimeter inlet, form a path, between evaporimeter gas outlet, compressor return air mouth, form a path, two paths are isolated mutually, two kinds of high and low temperature fluids circulate respectively in two paths of two sleeve pipes, save space, increase heat exchange simultaneously.Usually, as disclosed technology in the patent publication No. Chinese patent literature that is 103162470A, skin-pass connects condenser liquid outlet and evaporimeter inlet, flow through cryogen, internal layer path connects evaporimeter gas outlet and compressor return air mouth, flows through high temperature fluid, and this setup can be saved space, increase the heat exchange of a step high temperature fluid, cryogen simultaneously, improve air-conditioner efficiency.
Summary of the invention
The object that the utility model will reach is to provide a kind of two sleeve pipes of air-conditioning, improves the time of contact of unit cryogen and high temperature fluid, strengthens heat exchange.
In order to achieve the above object, the utility model adopts following technical scheme: two sleeve pipes of air-conditioning, comprise the first separatory cover, the second separatory cover, inner and outer tubes, the first separatory is arranged with the first entrance being connected with condenser liquid outlet, the second separatory is arranged with the first outlet being connected with evaporimeter inlet, and inner tube two ends are provided with the second outlet that is connected the second entrance with evaporimeter gas outlet and is connected with compressor return air mouth; Inner tube outer surface is evenly equipped with inner spiral groove, and outer pipe internal surface is evenly equipped with the external spiral groove identical with inner spiral groove pitch, the cross section of inner tube, and outer tube is placed on outside inner tube, and the external spiral groove of outer tube and the laminating of the inner spiral groove of inner tube form helical duct; Outer tube-surface is provided with two openings that connect to helical duct, and the first separatory cover, the second separatory cover are placed on outside outer tube, and the first entrance of the first separatory cover, the first outlet of the second separatory cover are communicated with two opening laminatings of outer tube respectively.
Inner tube is inserted outer tube, and after alignment, the inner spiral groove of inner tube and the external spiral groove of outer tube form airtight helical duct, it is skin-pass, cryogen covers into after helical duct from the first separatory, around inner tube outer surface motion, the path that unit cryogen is passed through extends continuously, with the high temperature fluid amplitude peak ground heat exchange of (being internal layer path) in inner tube.
Adopt after technique scheme, the utlity model has following advantage:
The heat exchanger time that has increased unit cryogen and high temperature fluid is long, makes the good heat dissipation effect of high temperature fluid.
