Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1-2, an ultra-thin manifold comprises a manifold 10, a header 20, a plurality of manifolds 30, and a plurality of blocking sheets 40. The main pipe 10, the water collecting pipe 20 and the shunt pipe 30 are all cylindrical and tubular. The two blocking pieces 40 are arranged, and the two blocking pieces 40 are respectively welded at two ports of the water collecting pipe 20 to block the water collecting pipe. The header pipe 10 is disposed through the wall of the header pipe 20 and communicated with the header pipe 20, and the header pipe 10 is fixedly disposed on the header pipe 20 by welding. The header pipe 10 is vertically disposed on a side wall of the header pipe 20, and the fixed position of the header pipe 10 is one end of the header pipe 20 in a length direction. The plurality of the shunt pipes 30 are arranged, each shunt pipe 30 is arranged to penetrate through the wall of the water collecting pipe 20 and is communicated with the water collecting pipe 20, each shunt pipe 30 is fixedly arranged on the water collecting pipe 20 in a welding mode, and each shunt pipe 30 is arranged on one side, far away from the header pipe 10, of the water collecting pipe 20. The welding method in this embodiment is preferably a shielded metal arc welding method. The shunt tubes 30 are arranged on the collecting pipe 20 at intervals, and the intervals between the adjacent shunt tubes 30 are equal.

Referring to fig. 3, a pressure stabilizer 50 is fixedly disposed in the water collecting pipe 20, and the pressure stabilizer 50 is integrally formed in the water collecting pipe 20. The pressure stabilizing piece 50 is provided with a pressure stabilizing hole 51, the pressure stabilizing hole 51 is arranged at the center of the pressure stabilizing piece 50, and the pressure stabilizing hole 51 penetrates through the pressure stabilizing piece 50. The pressure stabilizing pieces 50 are provided with a plurality of pieces, each pressure stabilizing piece is respectively arranged between the adjacent shunt tubes 30, and the number of the shunt tubes 30 is the same as that of the pressure stabilizing pieces 50. The pressure stabilizing holes 51 formed in the pressure stabilizing sheet 50 decrease in sequence from the position close to the header pipe 10 to the position far from the header pipe 10, and the diameters of the pressure stabilizing holes 51 decrease in sequence. When in use, the collecting pipe 10 conveys the refrigerant into the collecting pipe 20, and the refrigerant entering the collecting pipe 20 is respectively distributed to the branch pipes 30 through the arranged pressure stabilizing sheets 50. The pressure of the refrigerant just entering the header pipe 20 greatly meets the requirement of the pressure of the refrigerant in the shunt pipes 30 close to the header pipe 10, when the refrigerant flows to one end of the header pipe 20 far away from the header pipe 10, the pressure of the refrigerant is reduced due to the flow resistance in the pipeline, the flow is limited through the small pressure stabilizing holes 51 at the moment, the pressure of the refrigerant is enhanced, and therefore the pressure of the refrigerant in each shunt pipe 30 is ensured to be the same. The heat exchange performance of the air conditioner is improved, and the refrigerating or heating capacity of the air conditioner is enhanced.

Further, the pipe diameter of the water collecting pipe 20 is Φ C2, the pipe diameter of the header pipe 10 is Φ C1, Φ C2 is greater than Φ C1, that is, the pipe diameter of the water collecting pipe 20 is greater than the pipe diameter of the header pipe 10. The header pipe 10 is inserted and fixed in the header pipe 20 to form a T-shaped structure therewith. Compared with the traditional water collecting pipe 20 with the same pipe diameter as the main pipe 10, the pipe diameter of the water collecting pipe 20 is larger than that of the main pipe 10, and the resistance of the refrigerant flowing in the water collecting pipe 20 is reduced. The end of the main pipe 10 far away from the water collecting pipe 20 is provided with a gas discharging water discharging valve 60, and the gas discharging water discharging valve 60 is communicated with the main pipe 10. The air discharging and water discharging operations are carried out through the air discharging and water discharging valve 60.

Because the operation environment of the air conditioner outdoor unit is complex, certain corrosion can be generated on the welding point in a humid environment, and in order to ensure the long-term stability of the operation of parts, preferably, in the processing process of the manifold 10, after the welding process is finished, high-temperature paint is uniformly sprayed on the surface of the welding point after the welding is cooled, so that the corrosion prevention effect is achieved.
