Technical Field
[0001] This utility model relates to the field of power supply system technology, and in particular to a rectifier module. Background Technology
[0002] Given the current popularity of artificial intelligence and the explosive growth of data storage, the power requirements of AI have reached the megawatt level. Traditional rectifier modules have low rectification efficiency, complex structure, and require a large space, making it difficult to meet the rectification power supply needs of high power density devices in a limited space. Utility Model Content
[0003] The purpose of this utility model is to solve the shortcomings of existing rectifier modules on the market, such as low rectification efficiency, complex structure, large space occupation, and difficulty in meeting the rectification power supply requirements of high power density devices in a limited space, and to provide a rectifier module.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a rectifier module, installed in a cabinet, including a housing, a PCB board disposed in the housing, and a heat dissipation component disposed in the housing; the housing is installed in the cabinet by a snap-fit structure, a high-voltage connector is disposed on the PCB board, the housing includes a top cover and a bottom cover fixedly connected, and a panel fixed to the side of the top cover and the bottom cover, and the top cover and the bottom cover also have an insulating structure inside. By arranging multiple rectifier modules side-by-side within the cabinet using a snap-fit structure, the space utilization within the cabinet can be effectively improved, thereby increasing the number of rectifier modules and thus improving their rectification power supply efficiency. This allows the rectifier to meet the power supply requirements of high-power-density devices within a limited space. Furthermore, by using high-voltage connectors on the PCB board to connect the three-phase AC input to the rectifier modules and outputting the converted DC through these connectors, the rectification efficiency can be effectively improved while ensuring signal connectivity, enabling hot-swapping, and avoiding compatibility issues when multiple connectors are used. This further enhances the space utilization within the cabinet. Additionally, by using a heat dissipation component to expel heat from the housing through the panel, the heat dissipation effect and safety of the rectifier modules can be effectively improved. Moreover, the insulation structures within the top and bottom covers further enhance the overall safety of the rectifier modules.
[0005] Furthermore, the latching structure comprises several latches elastically connected to the sides of the bottom cover and a pressing part integrally formed with the latches, and the cabinet is provided with several slots for the latches to be inserted. 。The snap-fit structure uses double-sided countersunk rivets to press onto the sides of the bottom cover, with flat rivet positions on both sides, providing high strength. Made of stainless steel, the snap-fit structure offers excellent elasticity, facilitating easy engagement and disengagement from the rack's latches. Raised ribs and pre-bent angles on the snap-fit structure increase its rigidity. By pressing or releasing the pressing part of the snap-fit structure, the latch can be detached from or inserted into the rack's latches, effectively improving the convenience of detaching or inserting the rectifier module into the rack. Furthermore, multiple latches elastically connected to the sides of the bottom cover provide stronger locking force, resisting greater impact and enabling multi-point fixation of the rectifier module within the rack, thus significantly improving its stability.
[0006] Furthermore, the side of the bottom cover also has a bottom cover spring that abuts against the cabinet body of the server rack, and the PCB board is installed inside the bottom cover using press-fit studs. The bottom cover spring provided on the side of the bottom cover effectively ensures good contact between the bottom cover and the server rack body, optimizing electromagnetic interference. Moreover, by using press-fit studs and welding nuts to install the PCB board inside the bottom cover, the stability of the PCB board installed within the housing can be effectively ensured.
[0007] Furthermore, the insulating structure is an insulating plate fixed inside the top and bottom covers, which is installed inside the top and bottom covers using adhesive. By using adhesive to install the insulating plate inside the top and bottom covers, the ease of installation of the insulating plate can be effectively improved, enhancing the overall safety of the rectifier module. Simultaneously, the distance between the high-voltage circuit of the PCB board and the top and bottom covers is reduced, thereby decreasing the overall size of the rectifier module and increasing power density.
[0008] Furthermore, the top of the top cover has a top cover spring that abuts against the cabinet body of the cabinet. The top cover also has multiple mounting flanges, each with several first mounting holes. By overlapping the multiple mounting flanges of the top cover with the bottom cover, positioning and support are provided during installation. Bolts, studs, and pins are used to pass through the bottom cover and lock it into the mounting holes of the mounting flanges. This effectively ensures the stability of the fixed connection between the bottom cover and the top cover while allowing the fixed installation position of the top cover and the bottom cover to be moved upward, thus eliminating the need for clearance space for PCB boards or components and effectively improving the space utilization rate within the housing.
[0009] Furthermore, the panel is equipped with a handle, several LED indicator lights, and several ventilation holes arranged in a matrix. The entire panel undergoes a powder coating treatment, making it more aesthetically pleasing and textured. The ventilation holes are square vents arranged in a matrix on the panel, resulting in a high open area ratio while maintaining both aesthetics and good strength. The handle is located at the bottom of the panel, effectively improving the insertion and removal of the rectifier module within the cabinet. The handle has a circular cross-section and is powder-coated, making it both aesthetically pleasing and comfortable to hold. LED indicator lights are installed on the right side of the panel. When the rectifier module is in different operating states, the corresponding LED lights indicate this, effectively improving the user's convenience in monitoring the rectifier module.
[0010] Furthermore, the panel also has several fixing flanges for fixed connection with the housing and heat dissipation assembly, and the fixing flanges have several second mounting holes. By using bolts, studs, and pins to pass through the second mounting holes on the fixing flanges of the panel and lock them into the top and bottom covers, the stability of the fixed connection between the panel and the housing and heat dissipation assembly can be effectively improved.
[0011] Furthermore, the panel also has an O-ring inside that abuts against the heat dissipation component. This O-ring is elastic and can absorb vibrations from the heat dissipation component, thereby effectively improving its stability and reducing vibration noise.
[0012] Furthermore, the heat dissipation assembly includes several fans arranged side by side and mounting brackets for mounting the fans within the housing. The multiple side-by-side fans are connected in series and mounted on the mounting brackets using self-tapping screws. After the fans are mounted on the housing via the mounting brackets, there is a certain distance between the fan inlets and the panel, thereby effectively reducing wind noise.
[0013] Furthermore, the mounting bracket is provided with several third mounting holes for fixed connection with the housing. By using bolts, studs, and pins to pass through the top cover, bottom cover, and panel and lock them into the third mounting holes of the mounting bracket, the mounting bracket and panel together form the support structure of the fan, thereby giving the fan high installation strength and stability, and thus ensuring the stability and noise reduction effect when the fan is running at high speed.
[0014] The beneficial effects of the rectifier module provided by this utility model are as follows: By arranging multiple rectifier modules side by side in the cabinet using a snap-fit structure, the space utilization rate of the cabinet can be effectively improved, thereby effectively increasing the number of rectifier modules and thus effectively improving the rectification power supply efficiency of the rectifier module, achieving the rectification power supply requirements of high power density equipment within a limited space; In addition, by using the high-voltage connector on the PCB board to connect the three-phase AC input to the rectifier module and outputting the DC converted by the rectifier module through the high-voltage connector, the rectification efficiency of the rectifier module can be effectively improved while simplifying the structure of the rectifier module, further improving the space utilization rate of the cabinet; Furthermore, by using a heat dissipation component to blow the heat inside the housing out of the rectifier module through the panel, the heat dissipation effect and safety of the rectifier module can be effectively improved; In addition, the insulation structure set in the top and bottom covers can further improve the overall safety of the rectifier module.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0028] See Figure 1-5 The present invention provides a rectifier module 100, which is installed in a cabinet and includes a housing 10, a PCB board 30 disposed in the housing 10, and a heat dissipation component 20 disposed in the housing 10. The housing 10 is installed in the cabinet by a snap-fit structure 40. A high-voltage connector 31 is provided on the PCB board 30. The housing 10 includes a top cover 11 and a bottom cover 12 fixedly connected, and a panel 13 fixed to the side of the top cover 11 and the bottom cover 12. The top cover 11 and the bottom cover 12 also have an insulating structure 50 inside. By arranging multiple rectifier modules 100 side-by-side within the cabinet using a snap-fit structure 40, the space utilization within the cabinet can be effectively improved, thereby increasing the number of rectifier modules 100 and thus improving the rectification power supply efficiency of the rectifier modules 100. This allows the rectifier power supply requirements of high-power-density equipment to be met within a limited space. Furthermore, by using the high-voltage connector 31 on the PCB board 30 to connect the three-phase AC input to the rectifier module 100 and outputting the DC converted by the rectifier module 100 through the high-voltage connector 31, the rectification efficiency of the rectifier module 100 can be effectively improved while ensuring the signal connection of the rectifier module 100, enabling hot-swapping, and avoiding the problem of mismatch when multiple connectors are used, further improving the space utilization within the cabinet. Moreover, by using the heat dissipation component 20 to blow the heat from inside the housing 10 to the outside of the rectifier module 100 through the panel 13, the heat dissipation effect and safety of the rectifier module 100 can be effectively improved. In addition, the insulation structure 50 set in the top cover 11 and bottom cover 12 can further improve the overall safety of the rectifier module 100.
[0029] like Figure 1 and Figure 2 As shown, the latching structure 40 consists of several latches 41 elastically connected to the sides of the bottom cover 12 and a pressing part 42 integrally formed with the latches 41. The cabinet is provided with several slots for the latches 41 to be inserted. 。The snap-fit structure 40 is riveted to the side of the bottom cover 12 using double-sided countersunk rivets. The rivet positions on both sides are flat, providing high strength. Made of stainless steel, the snap-fit structure 40 offers excellent elasticity, facilitating engagement and disengagement with the cabinet's latches. Raised ribs and pre-bent angles on the snap-fit structure 40 increase its rigidity. By pressing or releasing the pressing part 42 of the snap-fit structure 40, the latch 41 can be disengaged from or inserted into the cabinet's latches, effectively improving the ease of detaching the rectifier module 100 from or inserting it into the cabinet. Furthermore, the multiple latches 41 elastically connected to the side of the bottom cover 12 provide stronger locking force, resisting greater impact and enabling multi-point fixation of the rectifier module 100 within the cabinet, thus effectively improving the stability of the rectifier module 100 within the cabinet.
[0030] like Figure 1 and Figure 2 As shown, the bottom cover 12 also has a bottom cover spring 121 on its side that abuts against the cabinet body of the server rack. The PCB board 30 is installed inside the bottom cover 12 by a press-fit stud 122. The bottom cover spring 121 on the side of the bottom cover 12 can effectively ensure good contact between the bottom cover 12 and the cabinet body, thus optimizing the electromagnetic interference problem. Furthermore, by using the press-fit stud 122 and welding nuts to install the PCB board 30 inside the bottom cover 12, the stability of the PCB board 30 installed inside the housing 10 can be effectively ensured. In addition, the insulation structure is an insulating plate fixed inside the top cover 11 and the bottom cover 12, which is installed inside the top cover 11 and the bottom cover 12 by adhesive backing. By using adhesive to install the insulating board inside the top cover 11 and bottom cover 12, the ease of installing the insulating board inside the top cover 11 and bottom cover 12 can be effectively improved, and the overall safety of the rectifier module 100 can be improved. At the same time, the distance between the high voltage circuit of the PCB board 30 and the bottom cover 12 and top cover 11 can be reduced, thereby reducing the overall size of the rectifier module 100 and increasing the power density.
[0031] like Figure 1 and Figure 2 As shown, the top cover 11 has a top cover spring 111 that abuts against the cabinet body of the cabinet. The top cover 11 also has multiple mounting flanges 112, and the mounting flanges 112 have several first mounting holes 1121. By overlapping the multiple mounting flanges 112 of the top cover 11 with the bottom cover 12, it serves as a positioning and support during installation. Bolts, studs, and pins are used to pass through the bottom cover 12 and lock it into the mounting holes of the mounting flanges 112. This effectively ensures the stability of the fixed connection between the bottom cover 12 and the top cover 11, while allowing the fixed installation position of the top cover 11 and the bottom cover 12 to be moved upward. This eliminates the need for clearance space for the PCB board 30 or components, thereby effectively improving the space utilization rate within the housing 10.
[0032] like Figure 3 and Figure 4 As shown, panel 13 is equipped with a handle 131, several LED indicator lights 132, and several ventilation holes 133, arranged in a matrix on panel 13. Panel 13 is coated with a powder coating, making it more aesthetically pleasing and textured. The ventilation holes 133 on panel 13 are square vents, arranged in a matrix, resulting in a high opening ratio while maintaining both aesthetics and good strength. The handle 131 is located at the bottom of panel 13, effectively improving the insertion and removal of rectifier module 100 in the cabinet. The handle has a circular cross-section and is powder coated, making it aesthetically pleasing and comfortable to hold. LED indicator lights 132 are installed on the right side of panel 13. When the rectifier module 100 is in different operating states, the corresponding LED lights indicate this, effectively improving the user's convenience in monitoring the rectifier module 100.
[0033] like Figure 3 and Figure 4 As shown, the panel 13 also has several fixing flanges 134 for fixed connection with the housing 10 and the heat dissipation assembly 20, and the fixing flanges 134 have several second mounting holes 1341. By using bolts, studs and pins and other locking components to pass through the second mounting holes 1341 on the fixing flanges 134 of the panel 13 and lock them into the top cover 11 and bottom cover 12, the stability of the fixed connection between the panel 13 and the housing 10 and the heat dissipation assembly 20 can be effectively improved.
[0034] like Figure 3 and Figure 4 As shown, the interior of panel 13 also has a rubber ring that abuts against the heat dissipation component 20. The rubber ring is an O-ring, which is elastic and can absorb the vibration of the heat dissipation component 20, thereby effectively improving the stability of the heat dissipation component 20 and reducing vibration noise.
[0035] like Figure 3 and Figure 4 As shown, the heat dissipation assembly 20 includes several fans 21 arranged side by side and mounting brackets 22 for mounting the fans 21 inside the housing 10. The multiple fans 21 arranged side by side are connected in series and mounted on the mounting brackets 22 with self-tapping screws. After the fans 21 are mounted on the housing 10 through the mounting brackets 22, there is a certain distance between the air inlet of the fans 21 and the panel 13, thereby effectively reducing wind noise.
[0036] like Figure 3As shown, the mounting bracket 22 is provided with several third mounting holes 221 for fixed connection with the housing 10. By using bolts, studs, and pins to pass through the top cover 11, bottom cover 12, and panel 13 and lock them into the third mounting holes 221 of the mounting bracket 22, the mounting bracket 22 and the panel 13 can together form the support structure of the fan 21, thereby giving the fan 21 high installation strength and stability, and thus ensuring the stability and noise reduction effect of the fan 21 when running at high speed.
[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
