Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
Referring to shown in Fig. 1 to Fig. 5, the refrigeration piping assembly of the present invention includes compressor, condenser, capillary tube 1, vaporizer and muffler 2.
Capillary tube 1 and muffler 2 are combined by the refrigeration piping assembly of the present invention, the cold-producing medium of flowing in capillary tube 1 with muffler 2 is utilized to carry out axially and radially heat exchange, substantially increase heat exchange efficiency, increase the expansion efficiency of capillary tube 1, make can shorten when obtaining identical heat transfer effect the total length of capillary tube 1 and muffler 2, save cost.Meanwhile, room temperature in described capillary tube 1 or high temperature refrigerant and the low-temperature refrigerant heat exchange inside described suction nozzle, thus effectively prevent, there is dew condensation phenomenon in muffler 2 outer surface.
Described capillary tube 1 has the interior pipe 11 being arranged at inside described muffler 2 and is arranged at the outer tube (not shown) outside described muffler 2.Said inner tube 11 is welded with the junction of described outer tube with described muffler 2, paste or is fixed together by fixture.Said inner tube 11 directly contacts with the cold-producing medium in described muffler 2, it is possible to along the radially, axially heat exchange simultaneously of capillary tube 1, substantially increase heat transfer effect.In order to said inner tube 11 be stably fixed in described muffler 2, described refrigeration piping assembly also includes being positioned at the fixture 3 inside described muffler 2.
The elastic component 32 that described fixture 3 has the annulus 31 being sheathed in said inner tube 11, extends to form to external radiation from annulus 31.In the form of sheets, support force is strong, and will not hinder the flowing of muffler 2 inner refrigerant for described elastic component 32.
The internal diameter of described annulus 31 is consistent with the external diameter of described capillary tube 1, to prevent the described relative said inner tube 11 of annulus 31 be moved or rock.The end of described elastic component 32 is connected on the inwall of described muffler 2, with fixing said inner tube 11.Described elastic component 32 has been bent to form a radian from annulus 31 terminad.During assembling, first described fixture 3 is sheathed in said inner tube 11, more slightly described capillary tube 1 is deep in described muffler 2 by extruding elastic component 32, by elastic component 32 reinstatement with fixing described capillary tube 1.
Further, said inner tube 11 includes the spire 111 that at least some of helically shape is arranged, and the diameter of described spire 111 is less than or equal to the internal diameter of described muffler 2, it is preferable that the diameter of described spire 111 is consistent with the diameter of described muffler 2.Said inner tube 11 designs in the shape of a spiral, can increase the contact area of described capillary tube 1 and described cold-producing medium on the one hand；On the other hand, under the premise that described muffler 2 length is certain, it is possible to the length of the interior pipe 11 holding described capillary tube 1 is longer, improves heat exchange efficiency further.
In the present embodiment, having one section of spire 111 in said inner tube 11, the two ends of described spire 111 are respectively provided with linear capillary tube 1, and the annulus 31 of described fixture 3 is sheathed on described linear capillary tube 1 part.Or said inner tube 11 is by spire 111 and linear type alternately design, and the annulus 31 of described fixture 3 is sheathed on described linear type capillary tube 1 part.Described linear type capillary tube 1 is preferably located at the center of described muffler 2.In this embodiment, the quantity of described elastic component 32 is at least 2, it is preferable that at least 3, and is symmetrical arranged, and described elastic component 32 bends facing one direction simultaneously, to increase balance and stability, and is easy to assemble with described capillary tube 1 and muffler 2.
Said inner tube 11 can also all be designed as spire 111.Correspondingly, as it is shown in figure 5, described fixture 3 includes at least two elastic component 32, described elastic component 32 is arranged at the side of described annulus 31, and described elastic component 32 bends symmetrically in opposite directions or dorsad, strengthens balance.When the pitch of described spire 111 is 0, the inwall of described muffler 2 is blocked by capillary tube 1 completely, and the end of described elastic component 32 is connected on described capillary tube 1, serves the same role.
In other embodiments, said inner tube 11 can also include the Z-type portion 112 arranged at least partially in zigzag shape, and described Z-type portion 112 includes be arrangeding in parallel the connecting portion 1123 in the 1121, second Z-type portion 1122 of the first Z-type portion and the first Z-type portion 1121 of connection and the second Z-type portion 1122.The 1121, second Z-type portion 1122 of described first Z-type portion and connecting portion 1123 are all fitted muffler 2 inwall.The 1121, second Z-type portion 1122 of described first Z-type portion and connecting portion 1123 are unanimous on the whole with the flow direction of described muffler 2 inner refrigerant, therefore can reduce the disturbance of cold-producing medium, reduce noise.In this embodiment, structure and the fixed form of described fixture 3 are same as the previously described embodiments, repeat no more in this.
Being different from above-described embodiment, said inner tube 11 can include at least some of spire 111 and at least some of Z-type portion simultaneously, and its fixed form is as above.
Present invention also offers a kind of refrigerator (not shown) including described refrigeration piping assembly, its good refrigeration effect, power saving.
In sum, the interior pipe 11 of described capillary tube 1 is fixed in described muffler 2 by fixture 3 by the capillary tube 1 of the refrigeration piping assembly of the present invention, make the said inner tube 11 refrigerant contact directly and in described muffler 2, along the axial of capillary tube 1 and radially two-direction heat-exchanging, improve the heat exchange efficiency of muffler 2 and capillary tube 1.It addition, this refrigeration piping assembly can be greatly shortened the total length of muffler 2 when obtaining identical heat transfer effect, provide cost savings.Meanwhile, room temperature in described capillary tube 1 or high temperature refrigerant and the low-temperature refrigerant heat exchange inside described suction nozzle, thus effectively prevent, muffler 2 outer surface occurring, condensation is existing.
Above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent replacement, without deviating from the spirit and scope of technical solution of the present invention.
