Abstract
The utility model discloses an energy-saving air-returning pipe assembly and a mould. The assembly comprises an air-returning pipe and a capillary tube, wherein a pressing groove is axially formed in the wall of the air-returning pipe and the capillary tube is embedded in the pressing groove. The air-returning pipe assembly disclosed by the utility model has the advantages that a pressing groove suitable for accommodating the capillary tube is stamped on the side wall of the air-returning pipe, so that the contact area of the air-returning pipe and the capillary tube is increased and the heat transfer performance is improved, therefore, the refrigerating efficiency of a refrigerator is improved and the power consumption is reduced.
Description
Technical field
The utility model relates to technical field of refrigeration equipment, especially relates to a kind of energy-conservation air-returning pipe component being applied on the refrigeration plants such as refrigerator.
Background technology
In traditional air return tube module of refrigerator, muffler and set-up mode capillaceous generally have two kinds: be respectively circumscribed and internal.The air-returning pipe component of the refrigerator of selling on the market is at present main mainly with circumscribed, and it adopts muffler and capillary also to lean on, then with aluminium foil, paste fastening technique.In the air-returning pipe component of circumscribed, the contact area of capillary and muffler is less, so its heat transfer effect is poor.In the air-returning pipe component of internal, capillary inserts the inner direct and cold-producing medium heat exchange of muffler, so its good effect of heat exchange, still, because capillary is in cold-producing medium, cold-producing medium is produced to flow-disturbing, has increased system noise.
Utility model content
The purpose of this utility model is to provide that a kind of heat transfer effect is good, the energy-conservation air-returning pipe component of circumscribed, to overcome the deficiencies in the prior art.
Another object of the present utility model is to provide a kind of processing mold of above-mentioned energy-conservation air-returning pipe component.
The technical solution of the utility model is: a kind of energy-conservation air-returning pipe component, comprise muffler, and capillary, is axially arranged with indent on described return-air tube wall, and described capillary is embedded in described indent.
At described muffler and outside capillaceous, paste aluminium foil.
The bottom profile of described indent and capillary cambered surface are suitable.
A mould for energy-conservation air-returning pipe component, for muffler punch process, comprises for holding the die cavity of muffler, and described die cavity cross section is circular, at the top of die cavity, has indent mouth.
The beneficial effects of the utility model are:
Air-returning pipe component of the present utility model is applicable to settling indent capillaceous by punching press on muffler sidewall, has increased the contact area of capillary and muffler, heat transfer performance is got a promotion, thereby improved refrigeration for refrigerator efficiency, reduces power consumption.
Accompanying drawing explanation
Fig. 1 is energy-conservation air-returning pipe component structural representation of the present utility model.
Fig. 2 is muffler punching press mould clamping structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Refer to Fig. 1, energy-conservation air-returning pipe component of the present utility model comprises muffler 2, and capillary 1 is axially arranged with indent 5 on described return-air tube wall, and described capillary 1 is embedded in described indent 5.At described muffler and outside capillaceous, paste aluminium foil (not shown).The bottom profile of indent 5 and capillary 1 cambered surface are suitable.
Refer to Fig. 2, the utility model need utilize special-purpose mould 3 first on the outer wall of muffler, to stamp out the indent caving inward, and the die cavity cross section of mould 3 is circular, at the top of die cavity, has indent mouth 4.Muffler 2 is through die cavity, and drift is aimed at the downward punching press of indent mouth, makes muffler outer wall indent, and formation can be embedded into indent capillaceous.
The processing method of the energy-conservation air-returning pipe component of the utility model is: first on the outer wall of muffler, stamp out the indent caving inward, then capillary is placed in indent, then with aluminium foil, muffler and capillary are pasted fastening.
Claims (4)
1. an energy-conservation air-returning pipe component, comprises muffler, and capillary is characterized in that: on described return-air tube wall, be axially arranged with indent, described capillary is embedded in described indent.
2. energy-conservation air-returning pipe component according to claim 1, is characterized in that: at described muffler and outside capillaceous, paste aluminium foil.
3. energy-conservation air-returning pipe component according to claim 2, is characterized in that: the bottom profile of described indent and capillary cambered surface are suitable.
4.
a kind ofthe mould of preparing energy-conservation air-returning pipe component claimed in claim 1, is characterized in that: comprise for holding the die cavity of muffler, described die cavity cross section is circular, at the top of die cavity, has indent mouth.
