Description
Technical field
The utility model relates to a kind of condensation pipe of air conditioner structure.
Background technique
Air conditioner connecting pipe is the pipe connecting between air conditioner outdoor machine and indoor set, and its effect is mainly the passage of refrigerant circulation between indoor apparatus of air conditioner and outdoor unit.The air conditioner connecting pipe using at present, its structure is: comprise copper pipe, pipe joint, thermal insulation casing, pipe joint is arranged on the end of copper pipe, and thermal insulation casing is sleeved on the outside of copper pipe, is also set with protection spring on copper pipe.The air conditioner connecting pipe of this structure is by the protective action of protection spring, and in the assembly process of air conditioner, copper pipe is not easy flatly to fall, and has both facilitated the installation of connecting tube, has stopped again to decline because of the heat pump performance that connecting tube distortion causes.
Because adopting red copper manufacture, above-mentioned copper pipe forms, red copper has good corrosion resistance, but cost is higher, in order to reduce manufacture cost, some copper pipes adopt metal composite pipe to replace the stage casing body of air conditioner connecting pipe, effectively reduce copper consumption, save cost, as stage casing body adopts aluminum pipe, tube head adopts copper pipe, between aluminum pipe and copper pipe, adopts welding technique to be connected.But there is the situations such as solder skip, rosin joint in welding, causes coolant leakage unavoidably, and when that stage casing body is aging is also more inconvenient need to change time.In addition, above-mentioned condensation pipe of air conditioner, owing to only having a copper pipe, the cold of cryogen medium therein is not fully used.
Summary of the invention
For above-mentioned technical problem, main purpose of the present utility model is for providing a kind of condensation pipe of air conditioner structure, the feature that the utlity model has reliable performance and the cold of low temperature refrigerant in connecting tube is fully used.
The technological scheme solving the problems of the technologies described above is as follows:
Condensation pipe of air conditioner structure, comprise copper pipe, aluminum pipe, thermal insulation casing, copper pipe and Al pipe butt welding are fixed, thermal insulation casing be set in copper pipe and outside, weld at copper pipe and aluminum pipe is provided with a joint, this joint be fixedly connected with aluminum pipe with copper pipe respectively, also comprise a secondary connecting tube, the external diameter of this pair connecting tube is less than the internal diameter of copper pipe and aluminum pipe, one end of secondary connecting tube passes from the end of copper pipe, the end of the other end aluminum pipe of secondary connecting tube passes, and secondary connecting tube is fixed with copper pipe and aluminum pipe respectively by support.
Adopted such scheme, adopted joint to connect copper pipe and the aluminum pipe of air conditioner connecting pipe, there is flexible operation, connect feature reliable, good seal performance, when aluminum pipe is aging need to change time, also can have been disassembled very easily.By secondary connecting tube, secondary connecting tube is for connecting the refrigerant passage of indoor set and outdoor unit; And copper pipe is also refrigerant passage.According to refrigerating state and the difference that heats state, secondary connecting tube can be used for carrying gaseous coolant or liquid refrigerants, can carry the physical state refrigerant relative with refrigerant physical state in secondary connecting tube in copper pipe.Because secondary connecting tube is positioned among copper pipe, and copper pipe has the length of several meters at least, so between copper pipe and secondary connecting tube, can carry out heat exchange comparatively fully, and the cold of low temperature refrigerant in connecting tube is fully used.
Further, the outer surface of described inner sleeve is comprised of conical surface and cylndrical surface, cylndrical surface is provided with screw thread, pressure pipe is positioned on the conical surface of inner sleeve and aluminum pipe is pushed down, the internal surface of described overcoat is comprised of conical surface section and cylinder section, cylinder section is provided with internal thread, the internal thread putting outward with in the outside thread that puts interconnect, the conical surface section putting is outward pushed down described pressure pipe.When rotary sleeve is threaded with inner sleeve, along with the displacement of overcoat, the conical surface section of overcoat is put with pressure pressure pipe, and pressure pipe presses to aluminum pipe like this, thereby aluminum pipe is clamped between overcoat and inner sleeve tightly.
Further, on copper pipe and aluminum pipe, be set with spring.By the protective action of spring, in the assembly process of air conditioner, copper pipe is not easy flatly to fall, and has both facilitated the installation of connecting tube, has stopped again to decline because of the heat pump performance that connecting tube distortion causes.
Further, described support comprises lasso, on the circumferential surface of lasso, is arranged at intervals with leg.This supporting structure can not form interference effect to copper pipe and secondary connecting tube, and can make medium manage as flowing.
