Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning accessories, and particularly relates to a branch structure of an automobile air-conditioning. Background Art

[0002] The current automotive air conditioner has higher and higher requirements for the system heat exchange efficiency. The splitter is a device that promotes uniform system splitting, which plays a vital role in improving the efficiency of the heat exchanger. The current automotive air conditioner splitter includes a refrigerant inlet pipe and multiple refrigerant splitter pipes. Due to the uneven mixing of the refrigerant gas and liquid flowing into the splitter from the refrigerant inlet pipe, the amount of refrigerant flowing out of each refrigerant splitter pipe is uneven, resulting in poor cooling effect of the automotive air conditioner. In view of this, we propose an automotive air conditioner splitter structure. Utility Model Content

[0010] The utility model has the following beneficial effects:

[0011] The utility model discloses a branch structure of an automobile air-conditioning. By arranging a mixing impeller inside a refrigerant mixing chamber, and driving the mixing impeller to rotate by the refrigerant entering the refrigerant mixing chamber, the mixing of the refrigerant inside the refrigerant mixing chamber can be accelerated.

By arranging an annular spoiler on the inner wall of the refrigerant branch pipe, when the refrigerant entering the refrigerant branch pipe flows to the annular spoiler, the external refrigerant will be blocked and move to the middle, and then can further contact and mix with the refrigerant continuously entering the refrigerant branch pipe from above, so that the refrigerant can be more fully mixed. By fixing a flow equalizing plate inside the refrigerant branch pipe and evenly opening through holes on the flow equalizing plate, the refrigerant flowing out of the refrigerant branch pipe can be more uniform, thereby making the cooling effect of the automobile air-conditioning more stable.

[0020] Embodiment 1: A car air conditioning branch structure, including a branch 1, the top of the branch 1 is fixedly connected to a refrigerant inlet pipe 2, and refrigerant channels 11 are symmetrically opened in the branch 1 below the refrigerant inlet pipe 2. The upper ends of the two refrigerant channels 11 are connected to the inside of the refrigerant inlet pipe 2, and the lower ends of the two refrigerant channels 11 are connected to a refrigerant mixing chamber 12 opened inside the branch 1. The inside of the refrigerant mixing chamber 12 is rotatably connected to a rotating shaft 4 through a bearing, and a mixing impeller 5 is sleeved and fixed on the rotating shaft 4. The refrigerant entering the inside of the branch 1 from the refrigerant inlet pipe 2 is The refrigerant can be gathered inside the refrigerant mixing chamber 12 after being diverted through the two refrigerant channels 11, and can drive the mixing impeller 5 to rotate, so that the refrigerant inside the refrigerant mixing chamber 12 is quickly mixed through the mixing impeller 5. An annular refrigerant chamber 14 is provided in the splitter 1 below the refrigerant mixing chamber 12. The refrigerant mixing chamber 12 is connected to the annular refrigerant chamber 14 through an annular connecting channel 13. The annular connecting channel 13 is a narrow annular channel, which can make the refrigerant entering the refrigerant mixing chamber 12 better in the refrigerant mixing chamber 12. The refrigerant stays inside so that the refrigerant can be more fully mixed, thereby improving the cooling effect of the air conditioner and making the cooling effect of the car air conditioner better. The bottom of the splitter 1 is fixedly connected with a refrigerant branch pipe 3. The refrigerant branch pipes 3 at the bottom of the splitter 1 are arranged in a ring array. The refrigerant branch pipe 3 is connected to the inside of the annular refrigerant cavity 14. The mixed refrigerant can be led out from the refrigerant branch pipe 3. When in use, the car air conditioning refrigerant can enter the splitter 1 through the refrigerant inlet pipe 2, and after being split by the two refrigerant channels 11, The refrigerants are combined in the refrigerant mixing chamber 12. During this process, the refrigerant entering the refrigerant mixing chamber 12 from the two refrigerant channels 11 can drive the mixing impeller 5 to rotate, so that the refrigerant inside the refrigerant mixing chamber 12 can be quickly mixed. The setting of the annular connecting channel 13 can prolong the residence time of the refrigerant in the refrigerant mixing chamber 12 and improve the mixing effect of the refrigerant. Finally, the mixed refrigerant can enter the annular refrigerant chamber 14 through the annular connecting channel 13, and finally realize the branching and diversion of the refrigerant through multiple refrigerant branch pipes 3.

[0021] Embodiment 2: The difference between this embodiment and embodiment 1 lies in that an annular spoiler 31 is provided on the inner wall of the refrigerant branch pipe 3, and three annular spoilers 31 are provided on the inner wall of the refrigerant branch pipe 3 at equal intervals from top to bottom. By providing the annular spoiler 31, when the refrigerant entering the refrigerant branch pipe 3 flows to the annular spoiler 31, the external refrigerant will be blocked and move to the middle, and then can further contact and mix with the refrigerant continuously entering the refrigerant branch pipe 3 from above, so that the refrigerant can be more fully mixed. A flow equalizing plate 6 is fixedly connected to the inner wall of the refrigerant branch pipe 3 below the annular spoiler 31, and a plurality of refrigerant branch pipes 3 at the bottom of the splitter 1 are provided in an annular array, so that the refrigerant flowing out of the refrigerant branch pipe 3 can be more uniform, thereby making the cooling effect of the automobile air conditioner more stable.

[0022] Working principle: When in use, the refrigerant of the automobile air conditioner can enter the splitter 1 through the refrigerant inlet pipe 2, and after being split by the two refrigerant channels 11, it converges in the refrigerant mixing chamber 12. In this process, the refrigerant entering the refrigerant mixing chamber 12 from the two refrigerant channels 11 can drive the mixing impeller 5 to rotate, so that the refrigerant inside the refrigerant mixing chamber 12 can be quickly mixed, and the setting of the annular connecting channel 13 can prolong the residence time of the refrigerant in the refrigerant mixing chamber 12 and improve the mixing effect of the refrigerant. Finally, the mixed refrigerant can be connected through the annular The channel 13 enters the annular refrigerant cavity 14, and finally realizes the branching and diversion of the refrigerant through multiple refrigerant branch pipes 3. When the refrigerant entering the refrigerant branch pipe 3 flows to the annular spoiler 31, the external refrigerant will be blocked and move to the middle, and then can further contact and mix with the refrigerant continuously entering the refrigerant branch pipe 3 from above, so that the refrigerant can be more fully mixed. When the refrigerant branch pipe 3 flows to the flow equalizing plate 6, it can flow out evenly and stably through the through hole 61, thereby making the cooling effect of the automobile air conditioner more stable.
