Description
Technical field
The utility model relates to refrigeration technology field, more particularly, relates to a kind of parallel-flow heat exchanger input and output pipe.
Background technology
Because China is the country of copper shortage of resources; The copper resource has satisfied not the demand of social development and economic construction far away, and therefore seeking the material Alloy instead of Copper that a kind of performance is close, price is lower, reserves are abundant is the practical problem that current refrigeration industry presses for solution.Nowadays the full aluminium heater of popular a kind of concurrent flow generally is used in air conditioning for automobiles, extraordinary air-conditioning, also is applied on the domestic air conditioning gradually simultaneously.Because the character of aluminum and the distinctive appearance of parallel-flow heat exchanger; Its hydrophily is very poor; Can not be applied on the air conditioner; Parallel-flow heat exchanger can only dispel the heat as condenser all the time, and pipelines such as the indoor heat exchanger of air-conditioning, compressor air-discharging, return-air also must adopt copper product, therefore uses this new type heat exchanger and also must link together with copper product.Usually design copper aluminium connects parallel-flow heat exchanger at input and output pipe place, through being welded together, uses the encapsulant encapsulation process to weld then.
There is very big difficulty in the industrial welding of thin wall copper aluminum pipe: pipe end banjo fixing butt jointing contact-making surface is narrow, causes the copper aluminum pipe welded joint poor sealing performance; The physical property difference of aluminum pipe and input and output is big, and the copper aluminium eutectic structure of fragility appears in heating easily to copper-aluminium joint, and the oxide of aluminum tube surfaces is easy-clear not; Generally all be to inject the input/output terminal of reducing processing in the aluminum pipe in the prior art, connect through the row soldering then that completion connects the back and with encapsulant connector made encapsulation process.But this type of connect all can not large-scale application to producing, and leak source appears in this type of welding easily.In addition, because copper and two kinds of metal physics nature differences of aluminium are big, copper aluminium junction is in the outside, is often corroded by humid air, and the time has been grown the soldering opening place and leak source can occur.The compressor exhaust pipe lateral pressure is big, and cold-producing medium is big to line shock power in the system, and the operation of air conditioner time is long, ruptures easily in copper aluminium junction.
The utility model content
The utility model purpose provides a kind of parallel-flow heat exchanger input and output pipe easy for installation, not cracky in order to overcome the deficiency that above-mentioned prior art exists.
The technical scheme that the utility model adopts is: a kind of parallel-flow heat exchanger input and output pipe; The discharge that comprises parallel-flow heat exchanger and collector tube, be connected compressor input pipe, connect efferent duct capillaceous; Also be included in the internal thread fixing hole of discharge and collector tube end setting, the copper sleeve that is provided with in the end of input pipe and efferent duct; Said copper sleeve is provided with external screw thread, is provided with the internal thread with the external screw thread of copper sleeve coupling in the said internal thread fixing hole.
Said copper sleeve is copper, and the circumference place of end is provided with the copper sleeve end chamfer, and said copper sleeve end chamfer is outside inclined-plane, and the root of said copper sleeve is provided with the copper sleeve spacing ring of a circle protrusion.
Said internal thread fixing hole inside is provided with the fixing hole inclined-plane, and the angle of inclination on said fixing hole inclined-plane and copper sleeve end chamfer are complementary.
The end of said internal thread fixing hole is a ring platform, and the internal diameter of said ring platform is less than the external diameter of copper sleeve spacing ring, and the external diameter of said ring platform is greater than the external diameter of copper sleeve spacing ring.
Be provided with sealing ring in said internal thread fixing hole and the copper sleeve, said sealing ring is arranged on copper sleeve spacing ring and the fixing hole inclined-plane.
Compared with prior art, the utlity model has following advantage:
1, adopt external screw thread to cooperate the fixing structure of internal thread to replace welding, quick and easy for installation;
2, in the junction of internal thread fixing hole and copper sleeve sealing ring is set,, prevents that the internal thread fixing hole from damaging because of vibration with buffering vibration.

The specific embodiment
Below pass through the specific embodiment, and combine accompanying drawing that the utility model is described further.
The utility model provides a kind of parallel-flow heat exchanger input and output pipe, and the cold-producing medium of the HTHP that comes out in the compressor gets into heat exchangers 1 cooling through input pipe 25, again from the efferent duct outflow heat exchanger.The utility model comprises internal thread fixing hole 22 on the discharge 21 that is connected on heat exchanger and the collector tube, is connected on the copper sleeve 24 on input pipe 25, the efferent duct.
Shown in Fig. 1-4, copper sleeve 24 is copper, and the side is provided with external screw thread 242, and the circumference place of end is provided with copper sleeve end chamfer 241, and copper sleeve end chamfer 241 is outside inclined-plane.The root of copper sleeve is provided with the copper sleeve spacing ring 243 of a circle protrusion
Internal thread fixing hole 22 internal diameters equate with copper sleeve 24 external diameters; In be provided with the internal thread 222 corresponding with external screw thread 242; The bottom is provided with fixing hole inclined-plane 221 241 corresponding with the copper sleeve end chamfer, that angle is complementary; The end is a ring platform, and its internal diameter is less than the external diameter of copper sleeve spacing ring 243, the external diameter external diameter greater than copper sleeve spacing ring 243.
On copper sleeve spacing ring 243 and fixing hole inclined-plane 221, be provided with sealing ring 23, its thickness is 2mm～3mm, plays good sealing function and when erection joint, plays cushioning effect, prevents that moment pneumatic screwdriver dynamics is excessive, causes internal thread fixing hole 22 to produce deformation.
