Description

Technical Field

[0001] This utility model relates to the field of modular power supply related products, specifically a modular power supply heat dissipation component. Background Technology

[0002] Modular power supplies are power supplies that can be directly mounted on printed circuit boards, providing power to application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field-programmable gate arrays (FPGAs), and other digital or analog loads. Due to the significant advantages of their modular structure, modular power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers, and other fields. Modular power supplies generate heat during operation; if this heat is not dissipated in time, it will affect the normal operation of the power supply. Therefore, heat dissipation components are installed on the power supply during installation.

[0003] Traditional modular power supplies typically use heat dissipation components such as heat-conducting plates. However, existing heat-conducting plate heat dissipation structures use glue to attach the heat-conducting plate to the upper surface of the power supply. Although this can achieve a heat dissipation effect, the heat-conducting plate cannot be removed after installation, which is not conducive to operations such as replacing the heat-conducting plate, and has defects. Utility Model Content

[0004] The purpose of this invention is to provide a modular power supply heat dissipation component to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular power supply heat dissipation assembly, comprising a modular power supply body and a heat dissipation mechanism. The heat dissipation mechanism includes a positioning frame, a mounting plate, and a heat dissipation frame. The positioning frame and the mounting plate are fixedly connected by two symmetrically arranged upright plates. Multiple heat dissipation fins are inserted into the mounting plate. The heat dissipation frame is fixed to the top of the mounting plate. Two symmetrically arranged cooling fans are installed on one side of the heat dissipation frame. Multiple heat dissipation slots are provided on the other side of the heat dissipation frame. Rotating slots are provided on both upright plates. Connecting rods are provided within the rotating slots. Threaded rods are fixedly connected to both ends of the connecting rods. The threads on the two threaded rods have opposite directions. The threaded rod is rotatably connected to the inner wall of the rotating groove at one end. A movable plate is threaded onto the threaded rod. A traction plate is rotatably connected to one end of the movable plate. A connecting plate is rotatably connected to one end of the traction plate. A clamping plate is fixedly connected to one side of the connecting plate. A first gear is fixedly sleeved on the connecting rod. A meshing second gear is provided on one side of the first gear. A rotating rod is fixedly inserted into the second gear. A sprocket is fixedly connected to one end of the rotating rod. The two sprockets are connected by a chain. One end of one of the rotating rods passes through the sprocket and is fixedly connected to a handle. A stop rod is slidably inserted into the handle. Multiple stop grooves corresponding to the stop rod are provided on the upright plate.

[0006] Preferably, the plurality of heat sinks are arranged at equal intervals, and the bottom end of the heat sink is in contact with the surface of the module power supply body.

[0007] Preferably, the upright plate is provided with an installation port communicating with the rotating groove, a bearing is installed in the installation port, and the rotating rod is fixedly inserted into the bearing.

[0008] Preferably, an anti-detachment block is installed at one end of the stop rod, and a spring is sleeved on the stop rod, with the two ends of the spring abutting against the anti-detachment block and the rotating block, respectively.

[0009] Preferably, two symmetrically arranged limiting rods are fixedly connected to one side of the card plate, and the limiting rods are slidably inserted into the upright plate.

[0010] Preferably, the card plate has a groove on one side, and the card plate is engaged with the end of the module power supply body.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The module power supply heat dissipation assembly works by fitting a positioning frame onto the module power supply body, and rotating the handle to make the rotating rod rotate. The sprocket on the rotating rod is connected by a chain. At this time, the rotating rod will cause the second gear to mesh with the first gear and rotate. At the same time, the connecting rod will rotate. Meanwhile, the moving plate on the threaded rod will cause the traction plate to move. The traction plate will push the connecting plate to use the clamping plate to hold the module power supply body and fix the mounting plate.

[0013] The power supply heat dissipation component of this module contacts the power supply body through a heat sink on the mounting plate. The heat sink conducts heat to the high temperature of the power supply body, and the cooling fan blows air onto the heat sink to achieve efficient heat dissipation.

[0014] The power supply heat dissipation component of this module is designed with clamping and fixing components, which facilitates the installation and removal of the heat dissipation component, making subsequent disassembly, maintenance and cleaning more convenient. Attached Figure Description

The heat dissipation mechanism includes a positioning frame 2, a mounting plate 3, and a heat dissipation frame 4. The positioning frame 2 and the mounting plate 3 are fixedly connected by two symmetrically arranged upright plates 5. Multiple heat dissipation fins 6 are inserted into the mounting plate 3.

Two symmetrically arranged cooling fans 7 are installed on one side of the heat dissipation frame 4, and multiple heat dissipation slots 8 are provided on the other side of the heat dissipation frame 4. Each of the two upright plates 5 is provided with a rotating groove, and a connecting rod 9 is provided in the rotating groove. Both ends of the connecting rod 9 are fixedly connected to threaded rods 10, with the threads on the two threaded rods 10 having opposite directions. One end of the threaded rod 10 is rotatably connected to the inner wall of the rotating groove. A movable plate 11 is threadedly sleeved on the threaded rod 10. One end of the movable plate 11 is rotatably connected to a traction plate 12, and one end of the traction plate 12 is rotatably connected to a connecting plate 13. A clamping plate 14 is fixedly connected to one side of the connecting plate 13. A first gear 15 is fixedly sleeved on the connecting rod 9. A meshing second gear 16 is provided on one side of the first gear 15, and a fixedly inserted part is inserted into the second gear 16. There is a rotating rod 17, one end of which is fixedly connected to a sprocket 24. The two sprockets 24 are connected by a chain 25. One end of the rotating rod 17 passes through the sprocket 24 and is fixedly connected to a handle 18. Specifically, by fitting the positioning frame 2 onto the module power supply body 1, rotating the handle 18 causes the rotating rod 17 to rotate. The sprocket 24 on the rotating rod 17 is connected by the chain 25. At this time, the rotating rod 17 will cause the second gear 16 to mesh with the first gear 15 and rotate. At the same time, the connecting rod 9 will rotate accordingly, and the moving plate 11 on the threaded rod 10 will also cause the second gear 16 to mesh with the first gear 15 and rotate. The traction plate 12 is moved, and the traction plate 12 pushes the connecting plate 13 to clamp the module power body 1 using the clamping plate 14 to fix the mounting plate 3. The heat sink 6 on the mounting plate 3 contacts the module power body 1, and the heat sink 6 conducts heat to the module power body 1 at high temperature. The cooling fan 7 blows air onto the heat sink 6 to achieve efficient heat dissipation. A stop rod 19 is slidably inserted on the handle 18, and multiple stop grooves corresponding to the stop rod 19 are provided on the upright plate 5. The stop rod 19 is inserted into the corresponding stop groove to fix the position of the clamping plate 14.

One end of the stop rod 19 is provided with an anti-detachment block 21, and a spring 22 is sleeved on the stop rod 19. The two ends of the spring 22 abut against the anti-detachment block 21 and the rotating block, respectively. The rebound force of the spring 22 causes the stop rod 19 to be firmly locked in the stop groove. Two symmetrically arranged limiting rods 23 are fixedly connected to one side of the clamping plate 14. The limiting rods 23 are slidably inserted into the upright plate 5 to increase the stability of both ends of the clamping plate 14. One side of the clamping plate 14 is provided with a groove, and the clamping plate 14 is locked at the end of the module power supply body 1.

[0025] The working principle of this modular power supply heat dissipation assembly is described in detail below: First, the positioning frame 2 is sleeved on the modular power supply body 1. By rotating the handle 18, the rotating rod 17 is rotated. The sprocket 24 on the rotating rod 17 is connected by the chain 25. At this time, the rotating rod 17 will cause the second gear 16 to mesh with the first gear 15 and rotate. At the same time, the connecting rod 9 will rotate. Meanwhile, the moving plate 11 on the threaded rod 10 will cause the traction plate 12 to move. The traction plate 12 will push the connecting plate 13 to clamp the modular power supply body 1 with the clamping plate 14 to fix the mounting plate 3. The heat sink 6 on the mounting plate 3 contacts the modular power supply body 1. The heat sink 6 conducts heat to the high temperature of the modular power supply body 1. The cooling fan 7 is turned on to blow air onto the heat sink 6 to achieve efficient heat dissipation.
