Description

Technical Field

[0001] This utility model relates to the field of inverter heat dissipation technology, specifically a compact heat dissipation structure for a new energy vehicle inverter. Background Technology

[0002] As a core component of power electronics, the inverter for new energy vehicles is responsible for converting the direct current output from the power battery into alternating current to drive the motor. Its technological development relies on power semiconductor devices, topology optimization, and control algorithm improvement. Early inverters used silicon-based IGBT modules. With the application of wide bandgap semiconductor materials, silicon carbide and gallium nitride devices have significantly improved switching frequency and reduced energy loss. Modern inverters have integrated intelligent control, temperature management, and fault diagnosis functions, and achieve efficient energy conversion through algorithms such as vector control and direct torque control. At the same time, lightweighting and high power density have become the direction of technological evolution in the industry, supporting the improvement of the range and performance optimization of new energy vehicles.

[0003] However, it still has some drawbacks. For example, the inverter heat dissipation structure usually adopts a fixed installation method, with the heat dissipation module and frame integrally formed or connected by complex fasteners, which leads to cumbersome installation and disassembly process and low maintenance efficiency.

[0004] To address the aforementioned issues, this application proposes a compact heat dissipation structure for a new energy vehicle inverter. Utility Model Content

[0005] The purpose of this utility model is to provide a compact heat dissipation structure for inverters in new energy vehicles, so as to solve the problem of inconvenient disassembly and maintenance of inverter heat dissipation structures mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a compact heat dissipation structure for a new energy vehicle inverter, comprising an inverter body, a compact mounting frame fixedly connected to the rear end of the inverter body, a modular heat dissipation module installed inside the compact mounting frame, and four sets of the modular heat dissipation module. A baffle knob is installed on the right side of the compact mounting frame. The modular heat dissipation module facilitates the free combination and expansion installation of multiple sets of modular heat dissipation modules through a simple and quick splicing method. This modular design not only greatly simplifies the installation process, but also provides great convenience for subsequent disassembly and maintenance, improving the ease of use and maintenance efficiency of the product.

[0007] Preferably, a mounting plate is fixedly connected to the lower part of the inverter body, and aluminum heat sink fins are fixedly connected to the upper part of the inverter body. The aluminum heat sink fins are provided in multiple sets, and input terminals are installed on the front of the inverter body.

[0008] Preferably, an output terminal is installed on the left side of the input terminal, a control terminal is installed on the left side of the output terminal, and an output indicator light is installed between the output terminal and the control terminal.

[0009] Preferably, the compact mounting frame has a heat dissipation mounting slot inside and on the right side, and sliding slots are installed on the upper and lower sides of the heat dissipation mounting slot. A main power supply socket is installed on the left side of the heat dissipation mounting slot, and a fan power supply male connector is detachable inside the main power supply socket.

[0010] Preferably, the male fan power connector is fixedly connected to the left side of the modular heat dissipation module, and the female fan power connector is installed on the right side of the modular heat dissipation module. The male fan power connector of one set of modular heat dissipation modules can be detached into the female fan power connector of another set of modular heat dissipation modules. Sliding strips are fixedly connected to the upper and lower sides of the modular heat dissipation module, and the sliding strips slide inside the sliding groove.

[0011] Preferably, the modular heat dissipation module is equipped with an industrial cooling fan. A detachable shielding plate is located on the right side of the modular heat dissipation module. The shielding plate is movable inside the right side of the compact mounting frame. A gear post meshes with one side of the shielding plate, and the gear post is movable inside the right side of the compact mounting frame. One side of the gear post is fixedly connected to a baffle knob. During installation, the sliding strips on the upper and lower sides of the modular heat dissipation module are precisely aligned with the sliding grooves inside the compact mounting frame, and then pushed horizontally into the heat dissipation mounting groove. The fan power connector on the left side of the first modular heat dissipation module is directly inserted into the main power socket on the left side of the compact mounting frame. Subsequent modular heat dissipation modules are connected via the fan power connector on the left side. Connect the fan power female connectors to the right side of the adjacent modules in sequence. After all modules are installed, rotate the baffle knob to cause the shielding toothed plate on the right side of the compact mounting frame to limit the end modular heat dissipation modules under the action of the gear column. For disassembly, rotate the baffle knob counterclockwise to rotate the gear column, driving the meshing shielding toothed plate to retract inward, releasing the mechanical limit on the end modular heat dissipation modules. At this point, any end modular heat dissipation module can be pulled out horizontally along the sliding groove. When a set of modular heat dissipation modules is removed, the fan power male and female connectors of its preceding and following end modular heat dissipation modules will separate, allowing all four sets of modular heat dissipation modules to be removed sequentially. Compared with the prior art, the beneficial effects of this utility model are: This utility model features a modular heat dissipation module that allows for easy and quick assembly, enabling the free combination and expansion of multiple modular heat dissipation modules. This modular design not only significantly simplifies the installation process but also greatly facilitates subsequent disassembly and maintenance, thereby improving the product's ease of use and maintenance efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In this embodiment, as shown Figures 1-2 As shown, the mounting plate 4 is fixedly connected to the bottom of the inverter body 1, and multiple sets of aluminum heat dissipation fins 3 are fixedly connected to the top of the inverter body 1. The input terminal 2 is mounted on the front area of ​​the inverter body 1, the output terminal 21 is arranged on the left side adjacent to the input terminal 2, the control terminal 23 is located on the left side adjacent to the output terminal 21, and the output indicator light 22 is embedded in the gap between the output terminal 21 and the control terminal 23.

[0016] In this embodiment, as shown Figures 3-4As shown, the heat dissipation mounting slot 51 is formed in the inner cavity and right side area of ​​the compact mounting frame 5. The sliding slots 52 are symmetrically arranged on the upper and lower edges of the heat dissipation mounting slot 51.

The left end face of the modular heat dissipation module 6 is fixedly connected to the fan power supply male connector 63. The fan power supply female connector 64 is assembled on the right end face of the modular heat dissipation module 6. Adjacent modular heat dissipation modules 6 are connected by the fan power supply male connector. 63 and fan power supply female connector 64 are detachably connected in series. Sliding bar assembly 62 is fixedly set on the upper and lower surfaces of modular heat dissipation module 6 and forms a sliding engagement with sliding groove 52. Industrial cooling fan 61 is built into the cavity of modular heat dissipation module 6. Baffle toothed plate 72 is detachably installed on the outer right side of modular heat dissipation module 6. Gear column 71 and the teeth of baffle toothed plate 72 form a meshing transmission relationship. Baffle knob 7 is linked with gear column 71 through a fixed connection. During installation, the upper and lower sides of modular heat dissipation module 6 are... The slider assembly 62 is precisely aligned with the sliding groove 52 inside the compact mounting frame 5 and pushed horizontally into the heat dissipation mounting groove 51. The male fan power connector 63 on the left side of the first modular heat dissipation module 6 is directly inserted into the main power socket 8 on the left side of the compact mounting frame 5. Subsequently, each modular heat dissipation module 6 is sequentially connected to the female fan power connector 64 on the right side of the adjacent module via the male fan power connector 63 on the left side. After all modules are installed, the baffle knob 7 is rotated so that the shielding toothed plate 72 on the right side of the compact mounting frame 5 moves against the gear column 71. When disassembling, the lower limit is used to hold the end modular heat dissipation module 6. Rotating the baffle knob 7 counterclockwise drives the gear column 71 to rotate, which in turn drives the meshing shielding tooth plate 72 to retract inward, releasing the mechanical limit on the end modular heat dissipation module 6. At this time, any end modular heat dissipation module 6 can be pulled out horizontally in the opposite direction along the sliding groove 52. When a set of modular heat dissipation modules 6 is removed, the male fan power connector 63 and the female fan power connector 64 of the front and rear end modular heat dissipation modules 6 will separate, thereby taking out the four sets of modular heat dissipation modules 6 in sequence.
