Description

Technical Field

[0001] This utility model relates to an inverter water nozzle, specifically an inverter housing with an integrated water nozzle. Background Technology

[0002] The inlet and outlet water nozzles of the inverter housing are die-cast and then assembled onto the housing. Iron water pipes are then installed on the water nozzles and connected to the cooling pipes. However, there is a high probability of leakage between the water nozzles and the housing, and between the water pipes and the water nozzles. At the same time, if the iron water pipes are defective, they are difficult to remove after being riveted on. Defective parts are difficult to remelt and can only be sold as scrap, resulting in high recycling costs. Utility Model Content

[0003] To address the shortcomings of the existing technology, this invention provides an inverter housing with an integrated water nozzle. This invention forms the water nozzle of the inverter housing in a one-piece molding manner, eliminating the need for separate water nozzles and iron water pipes, and directly connecting it to the cooling pipe interface. This greatly avoids leakage, reduces the purchase of water pipes, and results in low cost and short production cycle.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: an inverter housing with an integrated water nozzle, comprising a water nozzle integrally formed with the inverter housing, wherein a first positioning block, a second positioning block, and a third positioning block are provided on the outer periphery of the water nozzle, the included angle between the first positioning block and the second positioning block is a1, the included angle between the second positioning block and the third positioning block is a2, and the included angle between the first positioning block and the third positioning block is a3, wherein a1≠a2≠a3.

[0005] The outer end of the water nozzle is provided with a convex ring.

[0006] The inner wall of the water nozzle is provided with multiple reinforcing ribs, which are evenly distributed around the circumference.

[0007] The inner bottom of the water nozzle is provided with a transition slope.

[0008] The first positioning block, the second positioning block, and the third positioning block have the same thickness and are on the same horizontal line.

[0009] The width of the first positioning block is L1, the width of the second positioning block is L2, and the width of the third positioning block is L3. <L1 = L3。

[0010] a2 <a1<a3。

[0011] In summary, this utility model achieves the following technical effects: This utility model integrates the water tap with the inverter housing in a single molding process. The water tap is made of the same material as the inverter and is manufactured as a single piece. This replaces the previous die-casting and press-fitting water tap structure, eliminates the connection structure between the water tap and the inverter housing 1, thereby eliminating the gap at that point, preventing leakage at the source, and eliminating the press-fitting process of the water tap, shortening the processing cycle, and further reducing the phenomenon of damage to the inverter housing during die casting. The existing water pipes are directly machined, reducing product assembly processes and water pipe procurement. This reduces leaks caused by water pipe assembly, avoids delivery failures due to high product defects or the need to add CNC production lines, and lowers product assembly costs, giving the product a greater competitive advantage in the market.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] Example: Figure 1 This is a top view of an inverter housing with an integrated water tap. Figure 2 yes Figure 1 Referring to the cross-sectional view of the inverter housing, it includes a water nozzle 2, which is integrally formed with the inverter housing 1. A first positioning block 4, a second positioning block 5, and a third positioning block 6 are arranged on the outer periphery of the water nozzle 2. The included angle between the first positioning block 4 and the second positioning block 5 is a1, the included angle between the second positioning block 5 and the third positioning block 6 is a2, and the included angle between the first positioning block 4 and the third positioning block 6 is a3, wherein a1≠a2≠a3.

[0020] This utility model integrates the water tap 2 with the inverter housing 1 in a single molding process. The water tap is made of the same material as the inverter and is manufactured as a single piece, replacing the previous die-casting and press-fitting water tap structure. This eliminates the connection structure between the water tap and the inverter housing 1, thereby eliminating the gap and preventing leakage at the source. It also eliminates the press-fitting process of the water tap, shortens the processing cycle, and further reduces the phenomenon of damage to the inverter housing during die casting.

[0021] The outer end of the water nozzle 2 is provided with a protruding ring 201 to strengthen the port and facilitate connection with the cooling pipe interface.

[0022] A plurality of reinforcing ribs 3 are arranged on the inner hole wall of the water nozzle 2, and the plurality of reinforcing ribs 3 are uniformly distributed in the circumferential direction. The reinforcing ribs extend along the axial direction and are integrally processed with the water nozzle 2, which provides better strength, is not easy to break by bending, is not easy to damage, and also improves the connection strength with the cooling pipe.

[0023] A transition inclined surface 202 is provided at the inner bottom of the water nozzle 2, which is in transition connection with the hole groove 101 of the inverter housing 1, so as to enhance the thickness and strength of the root of the water nozzle.

[0024] The first positioning block 4, the second positioning block 5, and the third positioning block 6 have the same thickness and are located on the same horizontal line. The three positioning blocks can correspond to the three clamping grooves on the cooling pipe (not shown). When connecting the water nozzle and the cooling pipe interface, align the three positioning blocks with the three clamping grooves, and press directly to complete the assembly. The three pre-set positioning blocks serve as positioning references to prevent multiple connection attempts caused by misalignment between the water nozzle and the cooling pipe, and also avoid the phenomenon of gaps and leakage caused by completing the connection without proper alignment.

[0025] The width of the first positioning block 4 is L1, the width of the second positioning block 5 is L2, and the width of the third positioning block 6 is L3, where L2<L1 = L3.

[0026] In this utility model, the first positioning block 4 and the second positioning block 5 have the same structure but different widths L2 and L1, so that the two positioning blocks can be easily distinguished according to their sizes. The second positioning block 5 and the third positioning block 6 have the same width but different structures, which also allows quick distinction between these two positioning blocks, so that operators can quickly identify the three positioning blocks and their respective positions, and can quickly connect with the cooling pipe interface, with convenient and fast operation.

[0027] a2<a1<a3. The three positioning blocks of this utility model have different angles, forming an asymmetric structure, which is beneficial for operators to quickly distinguish the position of each positioning block, achieve quick alignment, and prevent incorrect insertion. In this embodiment, a1 is 105°, a2 is 90°, and a3 is 165°.

[0028] The above description is merely of preferred embodiments of the present utility model, and is not intended to limit the present utility model in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model shall all fall within the scope of the technical solution of the present utility model.
