Description

Technical Field

[0001] The utility model relates to the technical field of parallel rectification, in particular to a parallel rectification structure with high stability. Background Art

[0002] With the advancement of technology and the increasing level of industrial automation, higher requirements are being placed on power conversion systems, such as higher conversion efficiency, lower energy consumption, longer service life, and better thermal management. Parallel rectifier structures are designed to meet these demands, especially when handling high currents and high powers. A single rectifier may not be able to meet the requirements, but a parallel structure can provide the required power capacity. At the same time, current sharing technology ensures load balancing between modules, reducing the burden on individual modules and improving overall system reliability and efficiency.

[0003] In current parallel rectifier structure applications, especially in space-constrained environments, a double-layer design has become a common solution for optimizing space utilization and increasing the installation density of rectifier modules. This design can maximize the use of vertical space, thereby increasing the number of rectifier modules to meet high power requirements.

[0004] During the rectification process, the rectifier module will release a large amount of heat. If the thermal management measures are not in place, the heat generated by the lower module can easily affect the upper module through heat conduction and convection, and vice versa, forming a thermal superposition effect, causing the temperature of the entire system to rise abnormally. Excessive temperature will directly lead to performance degradation of the rectifier module, which is manifested as a decrease in conversion efficiency and unstable working state. It will also accelerate the aging of components inside the module and shorten its service life. In extreme cases, it may even cause thermal runaway of the module, causing the module to burn out, seriously affecting the safety and reliability of the system. Therefore, the present application provides a highly stable parallel rectifier structure to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0031] The following describes in detail a polymer material injection molding device provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative methods for implementing the invention in accordance with known techniques. Furthermore, the accompanying drawings are provided solely for the purpose of describing the embodiments in greater detail and are not intended to limit the present invention.

[0032] like Figure 1 - Figure 8 As shown, an embodiment of the present invention provides a parallel rectifier structure with high stability, including: a cabinet 1; two groups of support columns 6, arranged in the cabinet 1, and the two groups of support columns 6 are respectively located on two parallel inner walls of the cabinet 1; a placement frame 3, arranged between the two groups of support columns 6; an isolation plate 5, arranged in the placement frame 3, dividing the placement frame 3 into a first placement layer 31 and a second placement layer 32; a plurality of rectifier modules 4, respectively arranged in the first placement layer 31 and the second placement layer 32; a plurality of air holes 13, respectively arranged at the top and bottom of the isolation plate 5; a baffle 14, arranged in the isolation plate 5; a first air inlet 15, arranged on the side wall of the isolation plate 5; a second air inlet 7, arranged on the cabinet 1, and the second air inlet 7 corresponds to the first air inlet 15.

[0033] By setting up the baffle 14, it mainly acts on the inside of the isolation plate 5, guides the airflow, ensures the directionality of the air flow, avoids airflow chaos, and transports the air to the first placement layer 31 and the second placement layer 32 through the air vents 13, forming an orderly air flow circulation; by setting up the isolation plate 5, the purpose is to isolate the upper and lower layers of the rectifier modules 4, reduce the direct conduction of heat, avoid the heat generated by the lower module affecting the upper module, and vice versa, and prevent the heat superposition effect.

[0034] The second placement layer 32 further includes: a plurality of first heat dissipation holes 10, which are arranged on the top of the placement frame 3. The first heat dissipation holes 10 are provided to serve as outlets for hot air, and the hot air in the second placement layer 32 is discharged, thereby reducing the temperature inside the second placement layer 32.

[0035] The device further includes a plurality of second heat dissipation holes 11 provided on the sidewalls of the placement frame 3 and flush with the first placement layer 31. The second heat dissipation holes 11 serve as outlets for hot air, allowing the hot air in the first placement layer 31 to be discharged, thereby reducing the temperature inside the first placement layer 31.

[0036] The first placement layer 31 further includes a heat sink 12 disposed at the bottom of the placement frame 3. The heat sink 12 increases the heat exchange area and accelerates the transfer of heat from the first placement layer 31 to the surrounding environment, thereby reducing the temperature of the rectifier module 4 in the first placement layer 31.

[0037] The system further comprises two slide bars 9, detachably mounted on the top and bottom of the placement frame 3; and a partition plate 8, mounted within the placement frame 3, for isolating each rectifier module 4. The slide bars 9, mounted to the placement frame 3 by means of snaps, clamps, or bolts, provide a sliding path for the partition plates 8, allowing the position of the partition plates 8 to be quickly adjusted as needed to accommodate different rectifier module 4 layouts, while also providing a fixed position for the partition plates 8.

[0038] The top of the partition plate 8 is hooked and slidably engaged with the slide bar 9. The partition plate 8 is provided to physically isolate each rectifier module 4, reduce electromagnetic interference, facilitate independent installation and maintenance of the modules, and significantly reduce electromagnetic interference between modules.

[0039] The rectifier module 4 further includes a fixing rod 16, which is threadedly disposed on the partition plate 8 and is used to fix the partition plate 8. The fixing rod 16 is provided to provide a reliable fastening mechanism for fixing the partition plate 8 in the placement frame 3, ensuring that the partition plate 8 can be firmly fixed in the predetermined position and preventing the partition plate 8 from being displaced due to factors such as vibration or thermal expansion during the operation of the rectifier module 4.

[0040] The cabinet 1 further includes an air outlet window 2 provided at the top of the cabinet 1. The air outlet window 2 serves as an outlet for hot air, allowing the air that has absorbed heat from the rectifier module 4 to be discharged from the cabinet 1, thereby forming a complete air circulation path and preventing hot air from accumulating inside the cabinet 1.

[0041] The support column 6 includes: a first connecting column 61, one end of which is set in the cabinet 1; a second connecting column 65, which is set at the other end of the first connecting column 61; a buffer pad 66, which is set between the first connecting column 61 and the second connecting column 65; and a groove 62, which is respectively set on the first connecting column 61 and the second connecting column 65.

[0042] The first connecting column 61 is provided to fix the support column 6 inside the cabinet 1, thereby ensuring stable support and positioning of the placement frame 3, while providing sufficient strength and rigidity to bear the weight of the placement frame 3 and the rectifier module 4 therein.

[0043] It also includes: a two-way telescopic rod 63, which is arranged in the groove 62, and the two ends of the two-way telescopic rod 63 are respectively connected to the inner wall of the groove 62; a tension spring 64, which is sleeved on the surface of the two-way telescopic rod 63, and the two ends of the tension spring 64 are respectively connected to the inner wall of the groove 62.

[0044] By setting up the buffer pad 66, its main function is to provide physical buffering and reduce the structural stress caused by external vibration or internal thermal expansion and contraction; by setting up the bidirectional telescopic rod 63, it is extended and retracted when the first connecting column 61 and the second connecting column 65 are squeezed, and at the same time the tension spring 64 is compressed and deformed, providing elastic restoring force, helping the bidirectional telescopic rod 63 to return to its initial position after being subjected to force.

[0045] The technical solution provided by the present invention is to insert multiple partition plates 8 into the placement frame 3, and then pass the slide bar 9 through the hook on the top of the partition plate 8 and install it on the placement frame 3. After the partition plate 8 is moved to a suitable position, the fixing rod 16 is rotated to fix the partition plate 8, and then the rectifier module 4 is installed in the placement frame 3; when the system is started, the external cold air enters the cabinet 1 through the second air inlet 7 and enters the isolation plate 5 through the first air inlet 15. The air passes through the baffle 14 and the air vent 13 and enters the first placement layer 31 and the second placement layer 32 respectively; the air enters the first placement layer 31, Its rectifier module 4 absorbs heat, and the heat floats upward out of the placement frame 3 through the first heat dissipation hole 10; air enters the second placement layer 32, absorbs heat from its rectifier module 4, and the heat is discharged to the outside of the placement frame 3 through the second heat dissipation hole 11. At the same time, the heat generated by the second placement layer 32 is absorbed and dissipated through the heat sink 12, and finally the heat in the cabinet 1 is discharged to the outside through the air outlet window 2; when the cabinet 1 vibrates, the first connecting column 61 and the second connecting column 65 jointly squeeze the buffer pad 66, and at the same time the bidirectional telescopic rod 63 is bidirectionally telescopic, thereby reducing the external vibration from being transmitted to the placement frame 3.

[0046] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
