[0023] Referring to Figures 1-3 As shown, according to the embodiment of the present application, a shunt head includes a shunt head body 1; a shunt hole 2 is provided on the shunt head body 1; an installation area is provided in the shunt hole 2; the installation area is used for welding the shunt pipe 3; a welding diversion part 4 is provided in the shunt hole 2; the position of the welding diversion part 4 corresponds to the position of the installation area. The welding diversion part 4 is welded at the corresponding position of the installation area. When welding the shunt pipe 3, the welding diversion part 4 can guide the flow of the solder, thereby preventing the solder from accumulating and blocking the inner diameter of the shunt pipe 3 when welding the shunt pipe 3, so as to solve the problem that the solder flow is blocked and accumulated when welding the shunt pipe 3 on the shunt head, resulting in the blockage of the inner diameter of the shunt pipe 3; avoiding the welding blockage of the shunt head when welding the shunt pipe 3 can improve the production efficiency and reduce the quality hidden danger. The shunt pipe 3 is a capillary tube, usually with an outer diameter smaller than For example That is, the outer diameter is 4.76 and the wall thickness is 0.6.

[0024] See also Figure 5 As shown, the present application also discloses some embodiments, a mounting platform 5 is provided in the diverter hole 2; the mounting platform 5 is located at the mounting area; the mounting platform 5 is used for welding the diverter tube 3; the position of the welding guide part 4 corresponds to the position of the mounting platform 5, and the mounting platform 5 can locate the insertion depth of the diverter tube 3; however, the cutting edge of the diverter tube 3 is often uneven, and there will be a gap when it is assembled into the diverter head and matched with the mounting platform 5. During welding, the solder is easy to gather at the gap to form a weld nodule and block the diverter tube 3, resulting in production quality problems or abnormal operation of the unit; here, a welding guide part 4 is set at the corresponding position of the mounting platform 5. During the actual production and welding of the diverter tube 3, the large end of the diverter is placed upward on the welding tooling, and the diverter tube 3 is inserted for welding. Due to capillary action, the solder will flow downward along the outer wall of the diverter tube 3 and the inner wall of the diverter head hole. When the solder reaches the mounting platform 5, it will be guided away by the welding guide part 4, thereby avoiding the solder from flowing poorly at the root of the diverter tube 3 and gathering to form a weld nodule to block the diverter tube 3. The mounting platform 5 is a step formed on the inner surface, which is a step machined during machining and is a circular step. The inner diameter of the mounting platform 5 is smaller than the outer diameter of the capillary so as to block the capillary for positioning.

[0025] The present application also discloses some embodiments, in which the welding guide part 4 is a guide groove 41; the guide groove 41 is arranged on the inner wall of the diverter hole 2, that is, the guide groove 41 is arranged at the mounting platform 5, providing a channel for the flow of the solder, and will not be blocked by the accumulation of solder due to the obstruction of the step. In the actual production of the welding diverter tube 3, when the solder reaches the mounting platform 5, it will flow along the guide groove 41, thereby preventing the solder from flowing poorly at the root of the diverter tube 3 and gathering to form a weld nodule to block the diverter tube 3.

[0026] The present application also discloses some embodiments, in which the guide groove 41 is a strip groove; the strip groove extends in the direction of the central axis of the diversion hole 2.

[0027] The present application also discloses some embodiments, in which at least two guide grooves 41 are provided; at least two guide grooves 41 are circumferentially arranged around the inner surface of the diverter hole 2. At least two guide grooves 41 are evenly distributed on the inner wall of the diverter hole 2.

[0028] See also Figure 4 As shown, the present application also discloses some embodiments, the cross-sectional radius of the diverter tube 3 is R; the distance between the bottom of the guide groove 41 and the central axis of the diverter hole 2 is L; wherein L>R, which can better play a guiding role and prevent the solder from clogging the capillary.

[0029] The present application also discloses some embodiments, in which the guide groove 41 is a V-shaped groove, that is, a groove formed by the intersection of two inner walls, and the bottom of the groove is a sharp angle, which can better guide the flow of solder.

[0030] The present application also discloses some embodiments, in which a guide port is provided on the mounting table 5; the guide port is connected to the guide groove 41, and the guide port is on the mounting table 5. During the actual production and welding operation of the shunt tube 3, when the solder reaches the mounting table 5, it will flow into the guide groove 41 through the guide port, thereby preventing the solder from flowing poorly at the root of the shunt tube 3 and gathering to form a weld nodule to block the shunt tube 3.

[0031] The present application also discloses some embodiments, in which, on the cross section of the diverter hole 2, the guide groove 41 and the guide port have the same shape and size; and the guide groove 41 and the guide port correspond to each other in the direction of the central axis of the diverter hole 2, that is, the guide groove 41 is a through groove at the mounting platform 5, and when the solder reaches the mounting platform 5, it will flow downward along the capillary drainage groove on the inner wall, thereby avoiding the solder from flowing poorly at the root of the diverter tube 3 and gathering to form a weld nodule to block the diverter tube 3; the diverter head described here can solve the problem of welding blockage in the production of the diverter tube 3, so as to improve production efficiency.

[0032] According to an embodiment of the present application, an air conditioner is provided, including a diverter head, and the diverter head is the diverter head mentioned above.

[0033] The air conditioner is mainly composed of indoor and outdoor heat exchangers, compressors, controllers and system management. The existing air conditioners above 2P have a large number of pipes connecting the indoor and outdoor units. In order to reduce flow and pressure losses, the refrigerant needs to be divided into multiple branches. This will result in different refrigerant flows in each branch. In order to solve the problem of refrigerant flow distribution, the diverter head of the present application can be used, and then the length of the diverter pipe 3 or the number of U-shaped pipes can be adjusted to make it evenly distributed, thereby ensuring that the system can operate better. The air-conditioning unit uses a diverter, including a diverter head and a mainstream pipe.
