[0028] Embodiment:

[0029] A novel adjustable manifold assembly, as Figure 1-2 shown, includes a tee connector 1. The tee connector 1 includes an inlet end 11, a first outlet end 12 and a second outlet end 13. A main pipe 2 is connected to the inlet end 11, a first reducing pipe 3 is connected to the first outlet end 12, and a second reducing pipe 4 is connected to the second outlet end 13;

[0031] In a possible implementation, the three-way connector 1 is made by turning a herringbone blank. Step holes are drilled in the outer circles of the inlet end 11, the first outlet end 12, and the second outlet end 13 to form inner holes, and chamfers are formed at the outer ends of the inner holes to form outward-expanded holes.

[0032] Furthermore, the step holes are drilled to adjust the shunt ports according to requirements.

[0033] Furthermore, the chamfers inside the holes are for convenient installation with the reducer pipes and play a role in guiding the solder during welding.

[0034] Furthermore, the solder used for welding the three-way connector 1 and the reducer pipes is 4047 aluminum-silicon solder.

[0035] In a possible implementation, both the first reducer pipe 3 and the second reducer pipe 4 adopt an obtuse angle structure, and their obtuse angles are both 120°.

[0036] In a possible implementation, a number of solder flow channels 5 are provided on the side walls at the outer ends of the inner holes of the inlet end 11, the first outlet end 12, and the second outlet end 13. An extension groove 6 is provided at the end of the solder flow channel 5, and the head end of the solder flow channel 5 is connected to the outward-expanded hole.

[0039] By providing the solder flow channels 5, the outward-expanded holes, and the extension grooves 6, the welding area between the outer pipe and the ports of the three-way connector 1 is increased, and the welding is more stable.

[0040] Working principle: Refer to Figure 1-2 , use a herringbone blank for external shape and outer circle turning, drill step holes at the outer circles of the three ends, chamfer the inner holes, chamfer the edges, perform necking and then bending on the reducer pipes to make the reducer pipes achieve a reduced-diameter structure, and then cooperate with the turned adjustable three-way for welding to obtain a new type of manifold structure assembly.
