Description

Technical Field

[0001] The utility model belongs to a tube structure for an air-conditioning evaporator, in particular to a detachable copper tube assembly for an air-conditioning evaporator. Background Art

[0002] The evaporator is one of the important components of the air conditioner. At present, the evaporator input pipe assembly used in the air conditioner uses an output pipe with a larger diameter, which is connected to the condenser through the output pipe. The output refrigerant enters the condenser through a single channel, which affects the refrigeration efficiency. In order to improve the transmission efficiency of the refrigerant and realize heat exchange as soon as possible to achieve the refrigeration effect, some existing output pipes are divided into two. For example, the application number 201621410716.X discloses a split air conditioner, an indoor unit and an evaporator input pipe assembly, in which two mounting holes are extruded at the end of the input pipe to realize the installation of two shunt capillaries. When assembling this type of evaporator input pipe assembly, it is limited by the size of the end of the input pipe and the size of the shunt capillary. The end of the input pipe can only be connected to two shunt capillaries, so the shunt is limited; and when packaging and transporting, the input pipe and the shunt capillary need to be assembled and packaged at the same time, which takes up a lot of space and is inconvenient to transport.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] Reference Figure 1 to Figure 5 . A detachable copper tube assembly for an air conditioner evaporator comprises an input tube 1, a distributor 2, a first output tube 3, a second output tube 4, a third output tube 5 and a fourth output tube 6. The distributor 2 is detachably connected to one end of the input tube 1. Four connecting holes 21 are provided on the distributor 2. The four connecting holes 21 are respectively connected to the first output tube 3, the second output tube 4, the third output tube 5 and the fourth output tube 6. Among them, the aperture of the connecting hole 21 is consistent with the outer diameter of the connection point of each output tube, so that each output tube is tightly matched with the connecting hole 21; after each output tube is matched with the connecting hole 21, it is welded and fixed at the matching point, and nitrogen protection is carried out during welding, so that the output tube and the distributor 2 are tightly connected. Then the distributor 2 is connected to the input tube 1.

[0020] By providing the first output pipe 3, the second output pipe 4, the third output pipe 5 and the fourth output pipe 6, the refrigerant flowing into the input pipe 1 can be separated into four branch pipes to flow out, thereby realizing rapid diversion of the refrigerant, thereby facilitating heat exchange after increasing the refrigerant output and improving the refrigeration efficiency.

[0021] The distributor 2 includes a small end 22 and a large end 23. The distributor 2 is connected to the input pipe 1 through the small end 22. A threaded hole is processed on the small end 22. An external thread 11 is provided on the outer side of one end of the input pipe 1. The threaded hole is threadedly matched with one end of the input pipe 1, and the large end 23 is connected to the small end 22. Therefore, the external thread at one end of the input pipe 1 is threadedly matched with the threaded hole on the small end 22, which facilitates the installation and disassembly of the two. By providing the small end 22, the material consumption of the entire distributor 2 can be reduced, which is conducive to reducing the overall cost.

[0022] The distributor 2 further includes a tapered portion 24, and the small end portion 22 is connected to the large end portion 23 via the tapered portion 24. The tapered portion 24 facilitates a smooth transition from the small end portion 22 to the large end portion 23, and facilitates the refrigerant input from the input pipe 1 to be uniformly diffused to the large end portion 23 via the tapered portion 24, thereby achieving uniform flow distribution of the refrigerant in each output pipe.

[0023] The detachable copper tube assembly for the air conditioner evaporator of the utility model further comprises a pipe joint 7 and a pipe joint nut 8, wherein the pipe joint 7 is connected and fixed to the other end of the input pipe 1, and the pipe joint nut 8 is fixed to the pipe joint 7 by threaded fit. The pipe joint 7 can be welded and fixed to the other end of the input pipe 1, and the pipe joint nut 8 is sleeved on the pipe joint 7 by threaded fit. The pipe joint 7 is provided to facilitate the connection between the input pipe 1 and the external structure.

[0024] The outlet end of the first output tube 3 and the outlet end of the second output tube 4 are located on the same side of the distributor 2, and the outlet end of the third output tube 5 and the outlet end of the fourth output tube 6 are located on the other side of the distributor 2. Therefore, through the reasonable distribution of the outlet end positions of each output tube, each output tube does not interfere with each other when connected to the corresponding interface.

[0025] like Figure 1 and Figure 6 As shown, the input pipe 1, the first output pipe 3, the second output pipe 4, the third output pipe 5 and the fourth output pipe 6 are all provided with a protective layer 9 on the outside. The protective layer 9 can be an environmentally friendly electrophoretic paint layer made of phenolic resin or epoxy resin to increase the service life of each pipe.

[0026] The thickness of the protective layer 9 is 10 to 30 microns, so it can meet the use requirements and improve the overall service life.

[0027] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
