[0001] This utility model relates to the field of inverter housing technology, and in particular to an inverter housing structure with a water nozzle. Background Technology

[0002] With the development of the times, people are using inverters more and more widely, and in order to protect them, inverter housings are being used more and more extensively.

[0003] To address this, patent CN218499444U discloses an inverter housing, an inverter, and an energy storage device, belonging to the battery field. The inverter housing includes a cover plate, a base plate, and side plates, which together form the inverter housing. The base plate has holes for functional devices, and the side plates have terminal wiring holes. The side plates are detachably connected to the base plate. When producing inverter products with different power ratings, only the structure of the base plate needs to be changed to adapt it to the product, improving the compatibility of the inverter housing with different types of products. It has strong versatility, a simple structure, is easy to assemble, and saves costs.

[0004] The inverter housing described above is difficult to heat up by injecting coolant during use, which limits its application. Utility Model Content

[0005] The purpose of this invention is to provide an inverter housing structure with a water nozzle, in order to solve the shortcomings of existing inverter housing structures that are not convenient for quick injection of coolant to assist heat dissipation and for sealing to prevent leakage.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an inverter housing structure with a water nozzle, including a main body and a cover plate;

[0007] The top of the main body is provided with a cover plate, and fixing bolts are evenly inserted through the inside of the cover plate. A cooling pipe is installed on the inner wall of the main body. A reserved hole is opened on the outer wall of the main body on one side of the cooling pipe. A disassembly and assembly structure is opened on the inner wall of the reserved hole.

[0008] The disassembly and assembly structure includes a reserved groove opened on the inner wall of the reserved hole, a water injection nozzle is provided inside the reserved hole on the inner side of the reserved groove, a snap-fit ​​groove is evenly opened inside the water injection nozzle, an inclined block is provided inside the water injection nozzle, and a return spring is fixed on one side of the inclined block.

[0009] The inner wall of the main body is uniformly equipped with heat dissipation plates, and the interior of the reserved holes is provided with a sealing structure.

[0010] Preferably, all the fixing bolts extend into the interior of the main body, and the fixing bolts are threadedly connected to the main body.

[0011] Preferably, the reserved holes are interconnected with the cooling pipes, and the reserved slots are symmetrically distributed inside the main body.

[0012] Preferably, the inclined block is disposed inside the snap-fit ​​groove, and the inclined block and the water inlet nozzle form a snap-fit ​​structure through the snap-fit ​​groove.

[0013] Preferably, the heat sinks are evenly distributed on the inner wall of the main body, and the cooling pipes all penetrate the interior of the heat sinks.

[0014] Preferably, the sealing structure includes a threaded post disposed inside the reserved hole, a sealing ring disposed on one side of the threaded post, and a rotating plate fixed on one side of the threaded post.

[0015] Preferably, the diameter of the sealing ring is equal to that of the reserved hole, and the threaded post is threadedly connected to the reserved hole.

[0016] The inverter housing structure with a water nozzle provided by this utility model has the following advantages:

[0017] With a disassembly and assembly structure, the water nozzle is positioned inside the reserved hole by a locking structure consisting of a snap-fit ​​groove and an inclined block, making it difficult for the water nozzle to shift position. Pushing the water nozzle causes the inclined side of the inclined block to be squeezed and moved into the reserved groove, thus moving away from the snap-fit ​​groove and releasing the locking position. When the water nozzle is pulled out, rotating the water nozzle prevents the snap-fit ​​groove from passing through one side of the inclined block, thereby achieving the purpose of easy and quick disassembly and assembly of the water nozzle.

[0018] By incorporating a sealing structure, the threaded column forms a threaded connection inside the pre-drilled hole, which facilitates the rotation of the threaded column by a rotating plate. A sealing ring is placed on one side of the threaded column, allowing the sealing ring to be placed inside the pre-drilled hole for sealing. This prevents the coolant inside the cooling pipe from leaking, thus achieving the goal of preventing coolant leakage. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 The inverter housing structure with a water nozzle provided by this utility model includes a main body 1 and a cover plate 2.

[0027] Reference Figure 3 and Figure 4 As shown, a cover plate 2 is provided at the top of the main body 1. Fixing bolts 3 are evenly inserted through the interior of the cover plate 2 and extend into the interior of the main body 1. The fixing bolts 3 are threadedly connected to the main body 1. A cooling pipe 4 is installed on the inner wall of the main body 1. A reserved hole 5 is provided on the outer wall of the main body 1 on one side of the cooling pipe 4. A disassembly and assembly structure 6 is provided on the inner wall of the reserved hole 5. The disassembly and assembly structure 6 includes a reserved groove 601 opened on the inner wall of the reserved hole 5. A water inlet 602 is provided inside the reserved hole 5 inside the reserved groove 601. A snap-fit ​​groove 603 is evenly opened inside the water inlet 602. An inclined block 604 is provided inside the water inlet 602. A return spring 605 is fixed on one side of the inclined block 604. The reserved hole 5 and the cooling pipe 4 are interconnected. The reserved groove 601 is symmetrically distributed inside the main body 1. The inclined block 604 is located inside the snap-fit ​​groove 603. The inclined block 604 and the water inlet 602 form a snap-fit ​​structure through the snap-fit ​​groove 603.

[0028] During the operation of the inverter housing, internal heat dissipation is required. Therefore, heat dissipation plates 7 are evenly installed on its inner wall for heat dissipation, and cooling pipes 4 run through it, filled with coolant to further enhance cooling efficiency. To facilitate the injection of coolant through the water inlet 602, a disassembly and assembly structure 6 is provided. The water inlet 602 is directly inserted into the pre-drilled hole 5, and then pressed into the pre-drilled groove 601 by the inclined side of the wedge block 604. After the snap-fit ​​groove 603 on the outer wall of the water inlet 602 moves to the wedge block 604... From the side and rear, the return spring 605 pushes the inclined block 604 into the inside of the locking groove 603, thereby making the inclined block 604 and the locking groove 603 form a locking structure for positioning, so that the water nozzle 602 is not prone to positional displacement inside the reserved hole 5. After the injection is completed, the water nozzle 602 is further pushed so that it further squeezes the inclined block 604 into the inside of the reserved groove 601, thereby releasing the locking and positioning. Thus, when the water nozzle 602 is rotated, the locking groove 603 is not likely to pass through the side of the inclined block 604 when the water nozzle 602 is pulled out, thereby facilitating quick and easy disassembly and assembly of the water nozzle 602, which greatly increases the practicality of the device.

[0029] Reference Figure 5 As shown, heat dissipation plates 7 are evenly installed on the inner wall of the main body 1. The heat dissipation plates 7 are evenly distributed on the inner wall of the main body 1. Cooling pipes 4 all pass through the interior of the heat dissipation plates 7. A sealing structure 8 is provided inside the reserved hole 5. The sealing structure 8 includes a threaded post 801 provided inside the reserved hole 5. A sealing ring 802 is provided on one side of the threaded post 801. A rotating plate 803 is fixed on one side of the threaded post 801. The diameter of the sealing ring 802 is equal to that inside the reserved hole 5. The threaded post 801 is threadedly connected to the reserved hole 5.

[0030] After the coolant is injected into the cooling pipe 4, the reserved hole 5 needs to be sealed to prevent leakage. By setting a sealing structure 8, a rotating plate 803 is fixed on one side of the threaded post 801, which makes it easy to rotate the threaded post 801 into the reserved hole 5. This pushes the sealing ring 802 into the reserved hole 5 to achieve a sealing effect, thereby preventing the coolant from leaking inside the cooling pipe 4 and greatly increasing the practicality of the device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
