Description

Technical Field

[0001] This utility model relates to housings, specifically a converter housing. Background Technology

[0002] In modern power systems and industrial automation, converters play a crucial role, widely used in many key areas such as new energy power generation, motor drives, and power transmission and distribution. With continuous technological advancements, converters are evolving towards higher power density, higher efficiency, and higher reliability, which places increasingly stringent requirements on their enclosure design and performance.

[0003] Traditional converter housings are relatively simple in structural design, typically using a generic box shape, lacking refined design to address the complex component layout and functional requirements inside the converter. For example, in terms of component installation, existing housings often do not provide sufficient positioning and fixing structures. This means that installing various electronic components, power modules, heat dissipation devices, etc., inside the converter requires a significant amount of time and effort for debugging and securing. This is not only inefficient but also prone to problems such as insecure installation and messy wiring, affecting the converter's performance and stability, and also causing great inconvenience to subsequent maintenance and repair work.

[0004] Existing converter housings have many shortcomings in terms of structural design, heat dissipation performance, material strength, and protection capabilities, making it difficult to meet the actual needs of modern converters in complex working environments and under high-performance requirements.

[0020] The following is in conjunction with the appendix Figure 1-3 The specific embodiments of this utility model will be described in further detail.

[0021] Example 1, by Figure 1-3The present invention provides a converter housing, comprising a base plate 1, an end plate 2, an embedded groove 3, an auxiliary support plate 4, a first groove 5, a notch 6, a protruding eave 7, a back plate 8, a second groove 9, a round hole 10, and a recessed frame 11.

[0022] An end plate 2 is fixed to the front end of the base plate 1. An embedding groove 3 is provided on one side of the end plate 2 for installing and fixing specific components or parts, so that they are tightly integrated with the housing, thereby enhancing the overall stability and reliability. An auxiliary support plate 4 is fixed to the bottom of one side of the end plate 2. During installation, the auxiliary support plate 4 can provide additional support, which helps to place and fix the relevant components more stably, and also facilitates the wiring and routing of the components.

[0023] A back plate 8 is fixed to the rear end of the base plate 1. A first groove 5 is formed in the middle of the back plate 8. This groove can accommodate and fix irregularly shaped components, making full use of space and allowing for a more rational layout of components within the housing. A notch 6 is formed at one corner of the back plate 8. The notch 6 facilitates the entry and exit of wiring, preventing wiring from becoming tangled and messy inside the housing, thus improving the safety and reliability of electrical connections. A perpendicular protrusion 7 is provided at the top of the back plate 8. The protrusion 7 strengthens the structural strength of the back plate 8 and, in some installation scenarios, can also serve as a positioning reference during installation, making the installation of the housing and other equipment more precise and convenient.

[0024] A recessed frame 11 is provided at one end of the base plate 1. A second groove 9 is provided on the recessed frame 11. The combination structure of the recessed frame 11 and the second groove 9 can be used to install some special interface components or small heat dissipation devices, further expanding the function and applicability of the shell.

[0025] A circular hole 10 is provided in the middle of the base plate 1. The presence of the circular hole 10 helps the air to circulate inside the housing. Together with other heat dissipation designs, it can effectively dissipate the heat generated by the inverter operation and prevent the internal temperature from being too high and damaging the components.

[0026] In terms of material selection, the base plate 1 is made of 6mm thick aluminum plate. Aluminum plate has good thermal conductivity, which can quickly conduct the heat generated by the converter away, thus helping to dissipate heat. At the same time, aluminum plate also has high strength and light weight, which ensures the structural strength of the shell while facilitating handling and installation.

[0027] In addition, the surfaces of the base plate 1, end plate 2 and back plate 8 are all coated with a transparent passivation film. The transparent passivation film can effectively improve the corrosion resistance of the shell material, prevent corrosion in harsh environments such as humidity and acid / alkali, extend the service life of the shell, and maintain the clean and beautiful appearance of the shell.

[0028] In practical use: Installation process

[0029] When installing internal components of the converter, firstly, components that need to be fixed at the front end are embedded into the end plate 2 through the embedding groove 3 and placed on the auxiliary support plate 4 for initial positioning and support. Then, appropriate fasteners (such as bolts and nuts) are used to firmly fix the components to the end plate 2 and the auxiliary support plate 4. For components that need to be installed at the rear end, they are placed in the first groove 5 of the back plate 8, and adjusted and fixed appropriately according to the shape and size of the component to ensure that the component fits tightly in the groove and does not move inside the housing. At the same time, the wiring is led out of the housing through the notch 6, ensuring that the wiring is neat and orderly and avoiding problems such as tangling and short circuits. For some special interface components or small heat dissipation devices, they can be installed in the second groove 9 of the recessed bracket 11 and fixed. Throughout the installation process, attention should be paid to the installation position and orientation of each component to ensure that the electrical connection with the converter is correct.

[0030] Heat dissipation process

[0031] The heat generated during the operation of the converter is mainly conducted through the base plate 1 made of aluminum plate. Due to the good thermal conductivity of aluminum plate, the heat can be quickly transferred to the surface of the outer casing. At the same time, the circular hole 10 in the middle of the base plate 1 and other gaps and spaces in the outer casing form a natural air convection channel, allowing cold air from the outside to enter the interior of the outer casing, carry away the heat, and thus effectively reduce the temperature inside the outer casing, ensuring that the converter operates in a suitable temperature environment.

[0032] Protection process

[0033] The transparent passivation film coated on the surfaces of the base plate 1, end plate 2, and back plate 8 plays a crucial protective role. In humid environments, the passivation film prevents moisture from directly contacting the aluminum plate surface, thus preventing oxidation and corrosion. In environments containing corrosive substances such as acids and alkalis, the passivation film also acts as a barrier, mitigating the erosion of the aluminum plate by these substances, thereby extending the service life of the casing and ensuring reliable protection for the internal components of the converter.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
