Abstract
The utility model discloses aluminum muffler and the composite construction of capillary, it includes aluminium muffler, capillary, suppressed on the tube wall of aluminium muffler fluted, one layer of corrosion resistant coating is scribbled in groove, capillary is put in groove and fixes the rear reusable heat draw with heat-conducting glue band and is combined together with aluminium muffler thermoplastic.The depth of press flute is defined according to the external diameter of capillary on the aluminium muffler.Material selection copper, aluminium and alloy one kind therein of the capillary.The technical program is to set corrosion resistant coating to carry out preservative treatment in aluminium return-air pipe surface, avoids and because copper capillary tube directly contacts with aluminium muffler, solves refrigerator very well, the hidden danger that refrigeration system of refrigerator leaks.
Description
Technical field
A kind of composite construction of aluminum muffler and capillary is the utility model is related to, especially suitable for refrigeration industry, greatly
Used on the luxurious refrigerator such as capacity, air-cooled, refrigerator.
Background technology
In present refrigerator, refrigeration system of refrigerator, the muffler of compressor is returned with being flowed after condenser using evaporator stream
Heat exchange is carried out between the throttle capillary tube gone out high-pressure refrigerant is subcooled, improves refrigerating capacity.But used evaporator stream
It is usually copper pipe to return compressor return air pipe, but as the increasingly reduction of copper resource, its price gradually rise, there is aluminium in refrigeration industry
Substitute the trend of copper.Some household electrical appliances producers substitute copper pipe in order to reduce the dosage of refrigeration pipe copper, with aluminum pipe, and eliminate
Copper capillary tube with copper pipe soldering is compound is exchanged heat.But use aluminium muffler 1 directly to be contacted with copper capillary tube 2 and use aluminium foil glue again
Band 3 wraps up, and reaches heat transfer effect, and its shortcoming is：First, carried out because being provided between aluminium muffler and copper capillary tube at anti-corrosion
Reason, is easily leaked in use；Second, heat exchange efficiency is poor.
The content of the invention
Task of the present utility model is to propose a kind of aluminum muffler and capillary for improving heat exchange efficiency, avoiding corrosion
Composite construction.
Task of the present utility model is done in such a way that it includes aluminium muffler, capillary, it is characterised in that：Aluminium return-air
Suppress fluted on the tube wall of pipe, scribble one layer of corrosion resistant coating in groove, after capillary is put in groove and fixed with heat-conducting glue band
The reusable heat draw is combined together with aluminium muffler thermoplastic.The depth of press flute is according to the outer of capillary on the aluminium muffler
Footpath is defined.Material selection copper, aluminium and alloy one kind therein of the capillary.
The utility model has the following effects that：The technical program is to set corrosion resistant coating to carry out at anti-corrosion in aluminium return-air pipe surface
Reason, avoid because copper capillary tube directly contacts with aluminium muffler, solve refrigerator very well, refrigeration system of refrigerator leak it is hidden
Suffer from.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；Fig. 2 is the structural representation in Fig. 1 A-A directions.
Embodiment
Specific embodiment as depicted in figs. 1 and 2, suppressed on the tube wall of aluminium muffler 1 it is fluted, scribbled in groove one layer it is anti-
Corruption paint 2, capillary 3 are put in the groove for scribbling corrosion resistant coating and fix the pyrocondensation of the reusable heat draw 4 and aluminium muffler with heat-conducting glue band
Together, the depth of groove suppressed on the aluminium muffler is defined according to the external diameter of capillary to strong bonded, the capillary
Material selection copper, aluminium and alloy one kind therein, aluminium muffler both ends welding copper pipe is convenient to be connected with evaporator.
Aluminium muffler indentation groove of the technical program in the composite construction, surface applies corrosion resistant coating.Capillary is put into painting
In groove after paint, and fixed with heat-conducting glue band, be then secured together with heat-shrink tube pyrocondensation.So in copper capillary tube
Heat reaches heat transfer effect by being delivered to the groove contact surface on aluminum muffler in aluminum muffler.In aluminium muffler table
Face pressure sets groove, is contacted by original aluminium muffler with the point of capillary with point, has been changed to capillary and has been contacted with muffler face, carried
The high contact area of aluminium muffler and copper capillary tube, substantially increases heat exchange efficiency.Set simultaneously in aluminium return-air pipe surface anti-
Corruption paint carries out preservative treatment, avoids because copper capillary tube directly contacts the electrochemical corrosion caused by aluminum pipe with aluminium muffler, very
Good solves refrigerator, the hidden danger of refrigeration system of refrigerator leakage.
