In the technical solution of the utility model, also have following technical characterictic: described general import pipe is arranged on the straightway body of described arm a or described arm b.

In the technical solution of the utility model, also have following technical characterictic: described general import pipe is arranged on the bending section body of described arm a and described arm b.

In the technical solution of the utility model, also have following technical characterictic: described general import pipe is vertical with the plane of described U type pipe.

In the technical solution of the utility model, also have following technical characterictic: described U type pipe nominal overall diameter is φ 9.52mm, φ 7.94mm or φ 7.0mm.

In the technical solution of the utility model, also have following technical characterictic: described threeway adopts the precision die extrusion modling to make, and described arm a is identical with described arm b internal diameter.

The utility model compared with prior art has the following advantages and good effect:

The utility model adopts the precision die extrusion forming process to be processed into U type pipe, make two straight tubes of U type pipe become two arms, thereby two arm outlet internal diameters are identical, inside pipe wall surface uniformity is identical, it is almost completely identical with mass dryness fraction to enter upper and lower two branch road coil pipe refrigerant flows, each arm separatory uniformity greatly improves, thereby improves the air-conditioner operating condition, has effectively improved system's heating capacity and Energy Efficiency Ratio.

The specific embodiment

Embodiment 1

Referring to Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 11 and Figure 12, U type pipe threeway 2 is made in the threeway of condenser 3 usefulness, two straight lengths of U type pipe are arm a2-2 and arm b2-3, general import pipe 2-1 is positioned on the top arm a2-2, and general import pipe 2-1 is vertical with the plane of U type pipe threeway 2, referring to Fig. 6 and Fig. 7.

Above-mentioned U type pipe threeway 2 adopts the precision die extrusion forming process to make, and two arm a2-2 that come out with Mould Machining are identical with internal diameter with arm b2-3 external diameter, and the inside pipe wall surface roughness is identical.

The overall diameter of U type pipe threeway 2 is according to condenser U type pipe diameter, and commonly used have φ 9.52mm, φ 7.94mm, three kinds of nominal overall diameters of φ 7.0mm, according to the difference of U type pipe diameter, also has the threeway of other specification.

In Figure 11 and Figure 12, the direction of arrow is that cold-producing medium heats the flow direction.

During air-conditioner work, the vapour-liquid two phase refrigerant vertically flows to U type pipe threeway 2 from general import pipe 2-1, because the two ends caliber is in full accord, and agravic factor is separated influence, therefore the two phase refrigerant flow that enters two ends is consistent with mass dryness fraction, it is almost completely identical with mass dryness fraction promptly to enter upper and lower two branch road coil pipe refrigerant flows, thereby has effectively improved system's heating capacity and Energy Efficiency Ratio.

Embodiment 2

Different with embodiment 1 structure is that general import pipe 2-1 is arranged on the arm b2-3

Because embodiment 1 structural shape can overcome the influence that gravity factor causes the vapour-liquid two phase refrigerant to be separated in pipeline, guarantee that as far as possible cold-producing medium each branch road separatory in condenser 3 is even.

And embodiment 2 structural shapes can not overcome gravity factor, therefore, select the threeway of embodiment 1 for use as far as possible.

The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
