Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning accessories, in particular to a split copper shunt. Background Technique

[0002] An air conditioner is a device that can adjust the indoor air temperature, humidity, cleanliness, and air flow rate. It changes the indoor environmental conditions through the principle of refrigeration or heating to provide people with a comfortable living or working environment. The working principle of an air conditioner usually involves the coordinated operation of components such as a compressor, a condenser, an evaporator, and a throttling device. During the operation of the air conditioner, it is necessary to change the state of the refrigerant to adjust the indoor temperature. When the existing air conditioner needs to dissipate heat and condense the refrigerant during operation, the refrigerant is usually transported to the condenser through a copper pipe for condensation. Currently, general air conditioners transport the refrigerant to a single condenser. However, when using large air conditioners, in order to improve the power of the air conditioner, multiple condensers are usually required, and the condensers need to be shunted. Currently, a shunt is generally used for shunting, so that the refrigerant transported by the copper pipe is shunted into multiple copper pipes, thereby facilitating the connection of multiple condensers to work independently. The existing shunt is generally an integral structure. During processing, the material loss is large, it is not convenient for split independent turning processing, it is not convenient to reduce the processing difficulty and improve the material utilization rate, and it is not conducive to reducing the production cost of the shunt.

[0018] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0019] Embodiment 1: As shown in Figures 1-4 , it includes a flow splitting housing, the flow splitting housing includes a flow splitting pipe 100 and a confluence pipe 110. The connection between the flow splitting pipe 100 and the confluence pipe 110 is set as a rounded reduced-diameter structure. The diameter of the flow splitting pipe 100 is set to be twice the diameter of the confluence pipe 110. A flow splitting cylinder 200 is provided on the inner wall of the flow splitting pipe 100. The outer wall of the flow splitting cylinder 200 is in interference fit with the inner wall of the flow splitting pipe 100. Flow splitting holes 210 and mating holes 220 are evenly formed on the inner wall of the flow splitting cylinder 200. The diameter of the mating holes 220 is larger than the diameter of the flow splitting holes 210. The mating holes 220 are located at one end far from the confluence pipe 110. The port of the flow splitting cylinder 200 is located inside the flow splitting pipe 100.

[0020] The specific use scenario of this embodiment is as follows: By setting the connection between the flow splitting pipe 100 and the confluence pipe 110 as a rounded reduced-diameter structure, the structural stability of the flow splitting housing is improved. By setting the flow splitting housing and the flow splitting cylinder 200 as a split structure, it is convenient to independently process the flow splitting housing and the flow splitting cylinder 200, which helps to save processing materials. The materials of both the flow splitting housing and the flow splitting cylinder 200 are selected as metal copper, which has good heat conduction effects. By setting the outer wall of the flow splitting cylinder 200 in interference fit with the inner wall of the flow splitting pipe 100, it is convenient to assemble the flow splitting cylinder 200 and the flow splitting housing.

[0021] Embodiment 2: As shown in Figures 1-4 , a second copper pipe (not marked in the figure) is inserted into the inner wall of the mating hole 220 in a mating manner. The inner wall diameter of the second copper pipe is the same as the inner wall diameter of the flow splitting hole 210. A first tapered hole 230 is formed at the center of the outer wall of the flow splitting cylinder 200 near the flow splitting hole 210. There are several flow splitting holes 210, and the flow splitting holes 210 are evenly distributed around the first tapered hole 230. The flow splitting holes 210 are located outside the confluence pipe 110. A second tapered hole 240 is formed at the center position of the outer wall of the flow splitting cylinder 200, and the second tapered hole 240 is used to position the flow splitting cylinder 200.

[0022] The specific usage scenario of this embodiment is as follows: By setting the inner wall diameter of the second copper tube to be the same as the inner wall diameter of the shunt holes 210, after docking the second copper tube with the inner wall of the docking holes 220, the inner walls of the second copper tube and the shunt holes 210 are in equal-diameter docking, which improves the stability of refrigerant transportation, reduces the impact occurring inside the coolant and the split copper shunt, improves the stability of equipment operation, reduces the damage to the inner wall of the split copper shunt, and extends the service life of the split copper shunt. By setting the shunt holes 210 to be evenly distributed around the first tapered hole 230, the refrigerant can be evenly dispersed into multiple shunt holes 210.

[0023] The working principle of the present utility model is as follows: When in use by those skilled in the art, after the shunt housing and the shunt cylinder 200 are respectively machined by turning on a lathe, the shunt cylinder 200 is inserted into the interior of the shunt pipe 100. Through the interference fit between the shunt cylinder 200 and the inner wall of the shunt pipe 100, the end of the shunt cylinder 200 close to the shunt holes 210 is inserted from the port of the shunt pipe 100, and then through a hammering method, the shunt cylinder 200 is installed into the interior of the shunt pipe 100, making the connection between the shunt pipe 100 and the shunt cylinder 200 fit tightly. When in use, the first copper tube is connected by mating insertion with the inner wall of the confluence pipe 110, and several second copper tubes are respectively connected by insertion with the corresponding docking holes 220. Subsequently, in the form of laser welding, using metallic copper as the filler material, the second copper tubes and the docking holes 220 are welded together by laser welding, and the connection between the first copper tube and the confluence pipe 110 is welded. When the air conditioner needs to cold-shunt the refrigerant to multiple condensers during operation, the refrigerant is introduced into the shunt pipe 100 through the confluence pipe 110. Under the blocking action of the first tapered hole 230, the refrigerant is impacted and dispersed and then fills the entire interior of the confluence pipe 110. Subsequently, the refrigerant is evenly distributed into multiple shunt holes 210 and is led out to multiple corresponding condensers through the second copper tubes, improving the working efficiency of the equipment.

[0024] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
