Description
Technical field
The present invention relates to refrigeration technology field, particularly relate to a kind of return-air heat exchange tube assemblies and refrigeration plant.
Background technology
At present, the cold of cold-producing medium in muffler passes in the cold-producing medium in capillary by the return-air heat exchange tube assemblies on refrigeration plant, the refrigeration performance of raising equipment, existing return-air heat exchange tube assemblies structure type mainly contains: copper muffler is with capillary and weld formula, capillary is enclosed within built-in in muffler and use other materials muffler is rolled in capillary together with outer-enwraped type.
But, because of and to weld formula muffler material cost higher, built-in muffler capillary turnover muffler place needs welding, and slip is higher; At present, the return-air heat exchanger tube of the general inclined use outer-enwraped type of the refrigeration plants such as refrigerator, common outer-enwraped type return-air heat exchange tube structure as shown in Figure 1, muffler 1 and capillary 2 by integument 3 and together with, this mode cost is lower, makes simple, but due to capillary and muffler be linear contact lay, heat exchange area is less, and heat exchange efficiency is lower.
Summary of the invention
(1) technical problem that will solve
The object of this invention is to provide a kind of return-air heat exchange tube assemblies and refrigeration plant and solve the problem that cost is high, slip is high and heat exchange efficiency is low that existing return-air heat exchange tube assemblies structure exists.
(2) technical scheme
In order to solve the problems of the technologies described above, one aspect of the present invention provides a kind of return-air heat exchange tube assemblies, comprise muffler, capillary and integument, described capillary and the parallel setting of described muffler, described integument is looped around on described capillary and described muffler to make described capillary and described muffler be affixed, the position that described muffler is affixed with described capillary has recessed surface, and described recessed surface and described capillary are fitted.
Wherein, described muffler outer surface has anticorrosive coat.
Wherein, described anticorrosive coat is single or multiple lift.
Wherein, described muffler is copper pipe, aluminum pipe or plastic tube.
Wherein, described capillary is copper pipe, aluminum pipe or plastic tube.
Wherein, described integument is looped around on described capillary and described muffler with dividing multistage.
Wherein, described integument integral loop is around on described capillary and described muffler.
The present invention provides a kind of refrigeration plant on the other hand, and it comprises above-mentioned return-air heat exchange tube assemblies.
(3) beneficial effect
Technique scheme tool of the present invention has the following advantages: in return-air heat exchange tube assemblies provided by the invention and refrigeration plant, capillary and described muffler walk abreast and arrange and be affixed, in muffler, the cold of cold-producing medium passes in the cold-producing medium in capillary, thus improve the refrigeration performance of equipment, because the position that described muffler is affixed with capillary has recessed surface, described recessed surface and described capillary are fitted, like this, recessed surface and capillary are that face contacts, the contact area of capillary and muffler is larger, also namely heat exchange area is larger, and equipment heat exchange efficiency is high.
In addition, because heat exchange efficiency improves, the heat transfer effect that less tubing can be used to reach same, decreases the waste of material, shortening of muffler length, is convenient to muffler transport and produces assembling, and reducing the flow resistance of refrigeration system, improving refrigerating efficiency.

In figure, 1: muffler; 2: capillary; 3: integument; 4: anticorrosive coat; 5: recessed surface.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
In describing the invention, it will be appreciated that, orientation or the position relationship of the instruction such as term " " center ", " on ", D score, " vertically ", " level ", " top ", " end " " interior ", " outward " they be based on orientation shown in the drawings or position relationship; be only the present invention for convenience of description and simplified characterization; instead of instruction or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.
In describing the invention, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition above-mentioned term concrete meaning in the present invention can be understood.
As shown in Figures 2 and 3, return-air heat exchange tube assemblies provided by the invention, comprise muffler 1, capillary 2 and integument 3, capillary 2 and the parallel setting of described muffler 1, integument 3 is looped around on capillary 2 and muffler 1 to make capillary 2 and described muffler 1 be affixed, the position that muffler 1 is affixed with capillary 2 has recessed surface 5, and recessed surface 5 and described capillary 2 are fitted.
In above-described embodiment, capillary 2 and described muffler 1 walk abreast and arrange and be affixed, in muffler 1, the cold of cold-producing medium passes in the cold-producing medium in capillary 2, thus improves the refrigeration performance of equipment, because the position that described muffler 1 is affixed with capillary 2 has recessed surface 5, described recessed surface 5 is fitted with described capillary 2, like this, recessed surface 5 is with capillary 2 for face contacts, and capillary 2 is larger with the contact area of muffler 1, also namely heat exchange area is larger, and equipment heat exchange efficiency is high.
