Description

Technical Field

[0001] This utility model relates to the field of inverter bridge technology, specifically an inverter bridge mounting bracket. Background Technology

[0002] An inverter bridge is a core circuit structure in the field of power electronics for power conversion. Its main function is to convert direct current (DC) to alternating current (AC), or to regulate the frequency, voltage, and other parameters of AC power. It is widely used in power electronic equipment such as inverters, frequency converters, and UPS. An inverter bridge mounting bracket is a support or frame structure used to fix and install the inverter bridge, providing stable support and ensuring that the inverter bridge maintains a fixed position and orientation during operation, preventing vibration, displacement, and other factors from affecting its normal operation.

[0003] A search revealed a heat dissipation mounting structure for an IGBT full-bridge inverter module in an inverter welding machine, application number 201220436729.X. This structure includes an IGBT full-bridge inverter module, wherein two sets of IGBT transistors on one side of the IGBT inverter circuit board have the same power supply polarity, while two sets of IGBT transistors on the other side have opposite power supply polarities. The structure also includes a first heat sink, a second heat sink, and a third heat sink. The two sets of IGBT transistors with the same power supply polarity on one side of the IGBT inverter circuit board are mounted on the first heat sink, and the two sets of IGBT transistors with opposite power supply polarities on the other side of the IGBT inverter circuit board are mounted on the second and third heat sinks, respectively. This invention effectively dissipates heat from the four sets of IGBT transistors in the IGBT full-bridge inverter module and prevents short circuits in the IGBT transistors.

[0004] In the above technical solutions, only heat dissipation is provided for the installation structure. However, the installation structure and the inverter bridge cannot be easily disassembled and reassembled. If fixed bolts (such as multiple sets of countersunk bolts) or welding are used as non-quick disassembly connection methods, tools must be tightened one by one and the weld points must be cleaned during disassembly. Precise alignment is also required during reinstallation. A single maintenance may take several hours (or even more than half a day). For scenarios such as industrial production lines and new energy power plants that rely on the continuous operation of the inverter bridge, excessive downtime will directly lead to production interruption, loss of power generation revenue, and a significant increase in economic costs.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0022] Example 1: Please see Figure 1 - Figure 5 This is the first embodiment of the present invention. This embodiment provides an inverter bridge mounting bracket, including: a main substrate 1 and an inverter bridge 3, the inverter bridge 3 being disposed at the upper end of the main substrate 1, and further including: The heat dissipation assembly 2, the disassembly and locking assembly 4, and the disassembly and connection assembly 5 are provided. The heat dissipation assembly 2 is located at the bottom of the main substrate 1, the disassembly and connection assembly 5 is located at the connection between the main substrate 1 and the inverter bridge 3, and the disassembly and locking assembly 4 is installed on both sides inside the main substrate 1.

[0023] Specifically, the heat dissipation component 2 includes a connecting cover plate 201 and a plurality of heat dissipation fins 202. A plurality of heat dissipation fins 202 are fixedly installed on the bottom surface of the main substrate 1, and the connecting cover plate 201 is fixedly installed on the top surface of the heat dissipation fins 202.

[0024] Furthermore, the heat dissipation efficiency is improved and rapid maintenance is supported through structural optimization of the heat dissipation component 2. Multiple equidistantly distributed heat dissipation fins 202 are fixedly installed at the bottom of the main substrate 1, which significantly improves heat dissipation capacity by increasing the heat dissipation surface area and uniformly distributing the heat conduction path; the connecting cover plate 201 fixedly connected to the top of the heat dissipation fins 202 serves as both a support structure for the heat dissipation fins 202 and a continuous heat conduction surface through a covering design, thereby enhancing the heat conduction efficiency from the main substrate 1 to the heat dissipation fins 202.

[0025] Specifically, the heat dissipation assembly 2 further includes a heat dissipation bracket 203 and heat dissipation vents 206. A heat dissipation bracket 203 is provided on one side of the heat dissipation fin 202. Multiple heat dissipation vents 206 are provided inside the heat dissipation bracket 203. The heat dissipation assembly 2 also includes a drive motor 204 and heat dissipation blades 205. The drive motor 204 is fixedly installed inside the heat dissipation vents 206. The heat dissipation blades 205 are fixedly installed at the power output end of the drive motor 204. The heat dissipation assembly 2 also includes a heat dissipation channel 207. A heat dissipation channel 207 is formed between adjacent heat dissipation fins 202. The heat dissipation channel 207 is parallel and corresponding to the heat dissipation vents 206.

[0026] Furthermore, by setting a heat sink 203 with heat dissipation vents 206 on the side of the heat dissipation fins 202, a three-dimensional heat dissipation path is constructed. By setting a heat sink 203 with heat dissipation vents 206 on the side of the heat dissipation fins 202, a three-dimensional heat dissipation path is constructed. Through the specific structure heat dissipation channel 207 formed between adjacent heat dissipation fins 202, a directional airflow space is constructed, so that the forced airflow generated by the heat dissipation blades 205 can pass through the entire heat dissipation area along the preset path.

[0027] In use, by increasing the heat dissipation surface area and uniformly distributing the heat conduction path, the heat dissipation capacity is significantly improved. The connecting cover plate 201 fixedly connected to the top of the heat dissipation fins 202 serves as both a support structure for the heat dissipation fins 202 and a continuous heat-conducting surface through a covering design, enhancing the heat conduction efficiency from the main substrate 1 to the heat dissipation fins 202. The heat sink 203, as an airflow guiding structure, converts the lateral heat radiation generated by the heat dissipation fins 202 into a longitudinal airflow channel. The multiple heat dissipation ports 206 inside form a matrix ventilation array, causing the airflow direction to cross-convection with the extension direction of the heat dissipation fins 202, driving the motor 204. The installation position is located inside the heat dissipation vent 206, which can make full use of the space layout of the heat dissipation vent 206 and avoid external airflow interference. The direct connection between the heat dissipation blades 205 and the drive motor 204 can generate directional airflow through the high-speed rotation of the power output end, which can forcibly accelerate the heat exchange in the heat dissipation vent 206 area.

[0028] In summary, by using the main substrate 1 as the basic support structure and combining the collaborative design of the heat dissipation component 2, the disassembly and locking component 4, and the disassembly and connection component 5, dual optimization of heat dissipation and rapid maintenance is achieved. The inverter bridge 3 is fixed to the upper part of the main substrate 1 using a detachable installation method, providing a physical carrier for the subsequent component functions; the heat dissipation component 2 is arranged at the bottom of the substrate, avoiding direct contact with the inverter bridge 3 through spatial separation, while utilizing the bottom heat dissipation space to improve heat conduction efficiency; the disassembly and locking component 4 is built into both sides of the substrate, ensuring the stability of the inverter bridge 3 installation through a mechanical locking mechanism, and can be quickly released through unlocking operation during maintenance; the disassembly and connection component 5 is located at the joint between the substrate and the inverter bridge 3, realizing linear displacement assembly of the inverter bridge 3 through a sliding connection structure, significantly reducing disassembly and assembly steps compared to traditional bolt fixing. In the layout of each component, the heat dissipation component 2 is located at the bottom to avoid spatial interference with the upper disassembly mechanism. The locking component is embedded in the inside of the substrate on both sides to apply symmetrical constraint force. The sliding groove design of the connecting component directly forms an assembly guide on the upper surface of the substrate. This spatial distribution makes the heat dissipation path and the mechanical disassembly path form a three-dimensional separation, which not only ensures heat dissipation efficiency, but also ensures the convenience of disassembly operation.

[0029] Example 2: Please see Figure 1 - Figure 5 This is the second embodiment of the present utility model.

[0030] Specifically, the disassembly and locking assembly 4 includes a mounting groove 401 and a locking rod 402. The mounting groove 401 is formed on both sides inside the main body base plate 1. The locking rod 402 is slidably installed inside the mounting groove 401. The disassembly and locking assembly 4 also includes a top plate 403 and a spring 404. The top plate 403 is fixedly installed on the outer wall of the locking rod 402. The spring 404 is fixedly installed on one side of the top plate 403 inside the mounting groove 401.

[0031] Furthermore, the detachable locking function of the inverter bridge 3 mounting bracket is realized through the sliding fit structure between the mounting slot 401 and the locking rod 402, and the automatic reset function of the locking rod 402 is realized through the synergistic action of the top plate 403 and the spring 404.

[0032] Specifically, the disassembly and connection assembly 5 includes a connecting slider 501, an assembly slide 502, and a limiting top plate 503. The assembly slide 502 is formed on the upper end face of the main substrate 1. The connecting slider 501 is slidably installed inside the assembly slide 502, and the limiting top plate 503 is fixedly installed inside the assembly slide 502.

[0033] Furthermore, by assembling the sliding groove 502 and the connecting slider 501 through a sliding fit structure, the inverter bridge 3 can be linearly displaced along the groove direction, realizing tool-free quick insertion and removal.

[0034] In use, the mounting groove 401 is formed on both sides inside the main substrate 1, providing directional sliding space for the locking rod 402, allowing the locking rod 402 to move linearly within the mounting groove 401. The sliding installation method of the locking rod 402 allows it to quickly lock or unlock the inverter bridge 3 through push-pull actions. Compared with the traditional bolt fixing method, mechanical snap-fit ​​can be achieved without tools, significantly shortening the disassembly time. The design of the top plate 403 fixed to the outer wall of the locking rod 402 allows the top plate 403 to convert the elastic potential energy of the spring 404 into the axial displacement of the locking rod 402. When the external force is released, the spring 404 pushes the top plate 403 to drive the locking rod 402 to reset. The structural layout of the top plate 403 located inside the mounting groove 401 ensures a stable compression space for the spring 404 and, through the contact surface between the top plate 403 and the inner wall of the mounting groove 401, forms a limiting constraint to prevent excessive deformation of the spring 404. The design of fixing the top plate 403 to the outer wall of the locking rod 402 allows the top plate 403 to convert the elastic potential energy of the spring 404 into axial displacement of the locking rod 402. When the external force is released, the spring 404 pushes the top plate 403 to reset the locking rod 402. The structural layout of the top plate 403 located inside the mounting groove 401 ensures a stable compression space for the spring 404 and, through the contact surface between the top plate 403 and the inner wall of the mounting groove 401, forms a limiting constraint to prevent excessive deformation of the spring 404.

[0035] In summary, the assembly slide 502 of the disassembly and connection component 5 is integrated with the structure of the main base plate 1 to ensure sliding guidance accuracy and avoid jamming caused by gap deviation during disassembly. The fixed installation method of the limiting top plate 503 and the slide provides axial constraint on the slider, which can be pulled out in one direction simply by unlocking during disassembly, simplifying the operation steps.
