Description

Technical Field

[0001] This utility model relates to the technical field of battery pack cooling equipment, specifically to a nozzle assembly with adjustable spray angle. Background Technology

[0002] Battery packs in new energy vehicles may experience instantaneous overheating during system malfunctions, emergency braking, or severe collisions. Without immediate cooling, this could pose a fire hazard. Therefore, automatic cooling systems are typically required for battery packs. The structures of battery packs vary across different brands and models of new energy vehicles. To ensure efficient and rapid cooling by spraying the cooling agent onto the high-temperature areas of the battery pack, the nozzle assemblies in current battery pack cooling systems are mostly custom-designed. Different nozzle assemblies need to be designed for different brands and models of new energy vehicles. Figure 1 As shown, this nozzle assembly cannot adjust the spray angle, has poor versatility, cannot be interchanged, and has high design and manufacturing costs; secondly, the nozzles of the currently used nozzle assembly have circular outlets, resulting in a concentrated area of ​​sprayed cooling agent and insufficient coverage. Utility Model Content

[0003] The purpose of this invention is to provide a nozzle assembly with an adjustable spray angle, which can adjust the angle of the nozzle and the spray pipe, and the spray surface is fan-shaped, resulting in a wider spray range and greater versatility.

[0004] This utility model includes a connector with an inlet end and an outlet end. The outlet end of the connector is rotatably connected to a nozzle. The nozzle extends forward and is rotatably connected to a nozzle that communicates with the interior of the nozzle. A nozzle is provided on the front end face of the nozzle, and the nozzle penetrates the front end face of the nozzle and communicates with the interior of the nozzle.

[0005] With the above structure, the nozzle can rotate around the connector, allowing adjustment of its angle and direction according to the battery pack's structure to target the heat-prone areas, resulting in more precise spraying and better cooling. Secondly, the nozzle structure in this design is more slender, with two horizontal sections symmetrically distributed at the top and bottom of the vertical section, extending the nozzle to a wider area. This provides a wider adjustment range, broader coverage, and greater applicability, suitable for various battery pack models and structures. Finally, the nozzle's outlet is rotatably connected to a spray head that communicates with the nozzle's interior. The spray head's angle can be adjusted according to spraying needs and the nozzle's position; once adjusted, the spray head can be fixed in place. The spray head and nozzle work together to find the most suitable spray angle, improving the cooling effect.

[0006] Preferably, the nozzle is a bent pipe consisting of two horizontal sections and one vertical section, which is formed by bending a slender hollow tube. The two horizontal sections are distributed at the upper and lower ends of the vertical section and are respectively set perpendicular to the vertical section.

[0007] Preferably, the two horizontal pipe sections are centrally symmetrically distributed at the upper and lower ends of the vertical pipe section.

[0008] Preferably, the nozzle is a strip-shaped structure passing through the center of the front end face of the nozzle, and the nozzle extends through both radial ends of the nozzle.

[0009] Preferably, the nozzle has a triangular cross-section.

[0010] Preferably, a double-ended stud is also connected between the nozzle and the connector. Both ends of the double-ended stud are provided with external threads, and the interior of the double-ended stud is provided with a channel connecting the connector and the nozzle.

[0011] Preferably, the outlet end of the connector is provided with an internal thread, and the rear end of the double-ended stud is fixedly connected to the internal thread; the front end of the double-ended stud is connected to the nozzle by a fastening nut.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. The nozzle can rotate around the connector, allowing adjustment of its angle and direction according to the battery pack's structure, ensuring it targets areas prone to overheating for more precise spraying and better cooling. 2. The nozzle structure in this design is more slender, with two horizontal sections symmetrically distributed at the top and bottom of the vertical section, extending its reach further. This results in a wider adjustment range, broader coverage, and greater applicability to various battery pack models and structures. 3. The nozzle's outlet is rotatably connected to a spray head that communicates with the nozzle's interior. The spray head's angle can be adjusted according to spraying needs and the nozzle's position, and then fixed in place. The nozzle and nozzle work together to find the optimal spray angle, maximizing cooling efficiency.

[0014] 2. The nozzle is a strip-shaped structure passing through the center of the front end of the nozzle head, and the nozzle runs through both ends of the nozzle head radially. The cross-section of the nozzle is a triangular structure, and the final spray surface sprayed by the nozzle is fan-shaped. Compared with the spray surface of a circular nozzle, the fan-shaped spray surface covers a wider cooling range. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] The orientations mentioned in this specification are based on the orientation of the nozzle assembly with adjustable spray angle of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

[0022] like Figures 2 to 4 As shown, an adjustable spray nozzle assembly includes a connector 1, which has an inlet end and an outlet end. The inlet end of the connector 1 is connected to a cooling agent storage device, and the outlet end of the connector 1 is rotatably connected to a nozzle 2. Preferably, in this embodiment, the nozzle 2 is a bent tube consisting of two horizontal sections and one vertical section, formed by bending a slender hollow tube. The two horizontal sections are centrally symmetrically distributed at the upper and lower ends of the vertical section and are respectively perpendicular to the vertical section. Compared with the prior art, firstly, the nozzle 2 in this embodiment can rotate around the connector 1, allowing the angle and direction of the nozzle 2 to be adjusted according to the structure of the battery pack, making it more precise and effective in spraying over areas prone to overheating. Secondly, the nozzle 2 in this embodiment has a more slender structure, and the two horizontal sections are centrally symmetrically distributed at the upper and lower ends of the vertical section, allowing the nozzle 2 to extend to a farther area. The nozzle 2 has a wider adjustment range, a wider spray coverage, and greater applicability, making it suitable for various battery pack models and structures.

[0023] The nozzle 2 extends forward and is rotatably connected to the nozzle 3, which communicates with the interior of the nozzle 2. The angle of the nozzle 3 can be adjusted according to the spraying needs and the position of the nozzle 2. After the angle of the nozzle 3 is adjusted, the nozzle 3 can be fixed. The nozzle 3 and the nozzle 2 work together to find the most suitable spraying angle and improve the cooling effect.

[0024] like Figure 3As shown, a nozzle 301 is provided on the front end face of the nozzle 3. The nozzle 301 penetrates the front end face of the nozzle 3 and communicates with the interior of the nozzle 3. The nozzle 301 is a strip-shaped structure passing through the center of the front end face of the nozzle 3 and penetrates both ends of the nozzle 3 radially. The cross-section of the nozzle 301 is a triangular structure. Finally, the spray surface sprayed by the nozzle 301 is fan-shaped. Compared with the spray surface of the circular nozzle 301, the fan-shaped spray surface covers a wider cooling range.

[0025] like Figure 4 As shown, a double-ended stud 4 is connected between the nozzle 2 and the connector 1. Both ends of the double-ended stud 4 are provided with external threads, and the interior of the double-ended stud 4 is provided with a channel connecting the connector 1 and the nozzle 2. The outlet end of the connector 1 is provided with an internal thread, and the rear end of the double-ended stud 4 is fixedly connected to the internal thread. The front end of the double-ended stud 4 is connected to the nozzle 2 through a fastening nut 5. When in use, after adjusting the angle of the nozzle 2, tighten the fastening nut 5 to fix the nozzle 2.
