Abstract
Description
Technical Field
[0001] This utility model relates to the field of chassis technology, and in particular to an inverter chassis structure with integrated inductor and transformer potting components. Background Technology
[0002] The demand for residential photovoltaic energy storage inverters is increasing. Due to the need for heat dissipation, the inductor and transformer potting components in inverters often need to be placed on the outside of the product. Since outdoor inverters are required to meet the IP65 protection level, the inductor and transformer potting components need to be waterproof. Currently, the common method is to pot the inductor and transformer to the aluminum profile shell, and then lock them to the shell by attaching waterproof gaskets and screws. Since the aluminum profile shell needs to be threaded and the side covers at both ends need to be locked, the process is complicated. In addition, the inductor or transformer needs to be potted separately, waterproof gaskets need to be installed, and then locked into the shell. This is time-consuming and labor-intensive. Moreover, with long-term use, there is a risk of water ingress due to improper locking or aging of the waterproof gaskets, which can easily cause short circuits. Utility Model Content
[0003] To solve the above problems, the present invention adopts the following technical solution: an inverter chassis structure integrating inductor and transformer potting components, comprising: a chassis body, an inductor assembly, a transformer assembly, a first housing and two second housings;
[0004] The first housing and the two second housings are each disposed on one side of the chassis body. The transformer assembly is partially disposed inside the first housing and the other part abuts against the chassis body. The inductor assembly is partially disposed inside the two second housings and the other part abuts against the chassis body.
[0005] Furthermore, the chassis body is provided with a first connection port and two second connection ports, the interior of the first housing is connected to the first connection port, and the interior of each of the second housings is connected to the second connection port.
[0006] Furthermore, the first housing is welded to the chassis body as a single unit.
[0007] Furthermore, both second housings are welded to the chassis body as a single unit.
[0008] Furthermore, the inductor assembly includes an inductor body and a first connecting plate. The inductor body is disposed on the first connecting plate. Part of the inductor body is located in a second housing, and another part is located in another second housing. The first connecting plate covers two second connecting ports.
[0009] Furthermore, the transformer assembly includes a transformer body and a second connecting plate, the transformer body is disposed on the second connecting plate, the transformer body is located inside the first housing, and the second connecting plate covers the first connecting port.
[0010] Furthermore, the cross-sectional shape of the first connection port is the same as the cross-sectional shape of the second connection plate.
[0011] Furthermore, the chassis body is provided with a receiving groove, and the two second connection ports are provided in the receiving groove.
[0012] Furthermore, the cross-sectional shape of the receiving groove is the same as the cross-sectional shape of the first connecting plate.
[0013] Furthermore, both the first connecting plate and the second connecting plate are provided with glue inlets, each of which is used to inject glue for fixing.
[0014] The beneficial effects of this utility model are as follows: Using this inverter chassis structure with integrated inductor and transformer potting components, the installation of the chassis body, inductor components, transformer components, first housing, and two second housings significantly reduces the need for subsequent sealing measures and installation steps for the aluminum profile shell. The overall operation is simple and convenient, and the structure is straightforward. In other words, there is no need to use an aluminum profile shell that requires drilling threaded holes and locking side covers at both ends. Furthermore, the inductor and transformer components can be potted in one go, eliminating the need for transportation and relocation. During installation, no waterproof gasket is required, avoiding the risk of water ingress due to gasket aging. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings of the embodiments. This utility model is not limited to the following specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.
[0020] like Figures 1 to 3 As shown, an inverter chassis structure integrating inductor and transformer potting components includes: a chassis body 100, an inductor assembly, a transformer assembly, a first housing 400, and two second housings 500; the first housing 400 and the two second housings 500 are all disposed on one side of the chassis body 100, the transformer assembly is partially disposed within the first housing 400 and the other part abuts against the chassis body 100, the inductor assembly is partially disposed within the two second housings 500 and the other part abuts against the chassis body 100.
[0021] Specifically, the chassis body 100 has a first connection port 101 and two second connection ports. The interior of the first housing 400 communicates with the first connection port 101, and the interior of each second housing 500 communicates with the second connection port. The first housing 400 is welded integrally with the chassis body 100. Both second housings 500 are welded integrally with the chassis body 100. The inductor assembly includes an inductor body 210 and a first connecting plate 220. The inductor body 210 is disposed on the first connecting plate 220. Part of the inductor body 210 is located inside one second housing 500, and another part is located inside the other second housing 500. The first connecting plate 220 covers the two second connection ports. The transformer assembly includes a transformer body 310 and a second connecting plate 320. The transformer body 310 is disposed on the second connecting plate 320 and is located inside the first housing 400. The second connecting plate 320 covers the first connection port 101. The cross-sectional shape of the first connection port 101 is the same as that of the second connection plate 320. A receiving groove is provided on the chassis body, and the two second connection ports are located within the receiving groove. The cross-sectional shape of the receiving groove is the same as that of the first connection plate 220. Both the first connection plate 220 and the second connection plate 320 have glue inlets 600, each of which is used to inject glue for fixing.
[0022] During installation, the first housing 400 and the two second housings 500 are welded to the main body 100 of the chassis to form a single unit. Then, the transformer body 310 is placed inside the first housing 400, and the two parts of the inductor body 210 are placed inside the two second housings 500. At this time, the second connecting plate 320 connected to the transformer body 310 covers the first connecting port 101, and the first connecting plate 220 connected to the inductor body 210 covers the receiving groove. Since the cross-sectional shape of the first connecting port 101 is the same as that of the second connecting plate 320, and the cross-sectional shape of the receiving groove is the same as that of the first connecting plate 220, it effectively restricts the position, ensuring that the first connecting plate 220 and the second connecting plate 320 do not shift. Then, the inductor assembly and transformer assembly are potted and fixed through the potting port 600, which significantly reduces the need for subsequent sealing measures and installation steps for the aluminum profile housing. The overall operation is simple and convenient, and the structure is straightforward. This means there's no need for an aluminum profile housing that requires threaded holes and locking side covers at both ends. Furthermore, the inductor and transformer components can be potted in one go, eliminating the need for transport and handling. Waterproof gaskets are also unnecessary during installation, avoiding the risk of water ingress due to gasket aging. Notably, since the first housing 400 and the two second housings 500 are welded integrally to the main chassis 100, there's no need to lock the two second housings 500 housing the inductor components, or the first housing 400 housing the transformer components. This reduces installation steps and operating space, resulting in a smaller overall design size.
[0023] In summary, the above embodiments are not limiting embodiments of this utility model. Any modifications or equivalent variations made by those skilled in the art based on the substantive content of this utility model are within the technical scope of this utility model.
