Abstract

The utility model relates to the field of refrigeration, in particular to an air-conditioner connecting pipe connected with an indoor unit and an outdoor unit of an air conditioner. The air-conditioner connecting pipe is formed by a first connecting pipe section, a middle connecting pipe section and a second connecting pipe section in sequence in a butt-joint mode through flash welding or friction welding. The first connecting pipe section and the second connecting pipe section are copper pipe sections. The middle connecting pipe section is a non-copper-pipe metal section. Except that one end, connected with the indoor unit, of the air-conditioner connecting pipe and one end, connected with the outdoor unit, of the air-conditioner connecting pipe are kept unchanged and copper pipe sections are still adopted, the middle pipe section of the middle of the air-conditioner connecting pipe is changed into the non-copper-pipe metal section which is lower in cost and does not influence performance of the air conditioner. Therefore, a large section of copper pipe is saved, meanwhile, the performance of the air conditioner is also not influenced, and cost for manufacturing the air-conditioner connecting pipe is greatly reduced.

It is the copper pipe section that the described first connection pipeline section is connected pipeline section with described second; The metal segments of described intermediate connection tube Duan Weifei copper pipe.
Wherein, described intermediate connection tube section is the intermediate connection tube section that is formed by one section aluminum pipe section or an iron leg pipeline section.
Wherein, described intermediate connection tube section is for to dock the intermediate connection tube section that is welded mutually by the metal section more than two sections.
Wherein, described metal section more than two sections is metal section of the same race or dissimilar metal pipeline section.
Wherein, described first connects pipeline section docks with described intermediate connection tube section when welding, the internal diameter of the butt end of the described first connection pipeline section is less than the external diameter of the butt end of described intermediate connection tube section, and the external diameter of the butt end of the described first connection pipeline section is greater than the internal diameter of the butt end of described intermediate connection tube section; When described intermediate connection tube section and described second is connected pipeline section butt welding and connects, the internal diameter of the butt end of described intermediate connection tube section is less than the external diameter of the butt end of the described second connection pipeline section, and the external diameter of the butt end of described intermediate connection tube section is greater than the internal diameter of the butt end of the described second connection pipeline section.
Wherein, the described first connection pipeline section, described intermediate connection tube section and described second are connected pipeline section and are isometrical pipeline section.
Wherein, described intermediate connection tube section is tapered pipeline section or gradually expanded form pipeline section, and it is waney pipeline section that the described first connection pipeline section is connected pipeline section with described second.
Wherein, described first connects pipeline section is connected the identical length of pipeline section with described second same.
The application's beneficial effect:
The application's the air conditioner connecting pipe that is used for connecting indoor apparatus of air conditioner and off-premises station, made into to be welded to form by solderless flash welding or friction welding (FW) butt joint by three sections pipes, an end that connects an end of indoor set and connect off-premises station except air conditioner connecting pipe remains unchanged, still adopt outside the copper pipe section, the middle pipeline section of the mid portion of air conditioner connecting pipe has made into lower-cost but has not influenced the metal segments of the non-copper pipe of heat pump performance, thereby saved the copper pipe of a big section, do not influence simultaneously the performance of air-conditioning again, but reduced the cost of making this air conditioner connecting pipe greatly.
Description of drawings
Utilize accompanying drawing that the application is described further, but the embodiment in the accompanying drawing does not constitute any restriction to the application, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to the following drawings.
Fig. 1 is the structural representation of a kind of air conditioner connecting pipe of the application.
Reference numeral:
The 1-indoor set, the 2-off-premises station, 3-first connects pipeline section, 4-intermediate connection tube section, 5-second connects pipeline section.
The specific embodiment
With the following Examples the application is further described.
A kind of air conditioner connecting pipe, be used for connecting indoor set 1 and the off-premises station 2 of air-conditioning, as shown in Figure 1, air conditioner connecting pipe has been made into to connect pipeline section 3 by first by the structure of whole traditional copper pipe, intermediate connection tube section 4 is connected 5 three sections of pipeline sections and is docile and obedient order and is welded to form by flash welding butt joint welding or friction welding (FW) butt joint with second, the part that just the air conditioner connecting pipe two ends is used for connection indoor apparatus of air conditioner 1 and off-premises station 2 remains unchanged, namely first connects pipeline section 3 and is connected pipeline section 5 with second and still adopts the copper pipe section, and other are lower-cost but do not influence the material of heat pump performance and the pipeline section of mid portion changed into.
First connects pipeline section 3 docks with intermediate connection tube section 4 when welding, the internal diameter of the butt end of the first connection pipeline section 3 is less than the external diameter of the butt end of intermediate connection tube section 4, and the external diameter of the butt end of the first connection pipeline section 3 is greater than the internal diameter of the butt end of intermediate connection tube section 4; And when middle tube connector section 4 is connected pipeline section 5 butt joint welding with second, the internal diameter of the butt end of intermediate connection tube section 4 is less than the external diameter of the butt end of the second connection pipeline section 5, and the external diameter of the butt end of intermediate connection tube section 4 is greater than the internal diameter of the butt end of the second connection pipeline section 5.
