A low-voltage winding module detachable transformer rectifier

Abstract

This application relates to a low-voltage winding module detachable transformer rectifier, including a rectifier body. A hollow heat dissipation mesh is detachably installed on the upper end of the rectifier body, with its lower end fitting against the upper end of the rectifier body. A cover plate is detachably installed on the upper end of the heat dissipation mesh. In this application, heat from the upper end of the rectifier body can be exchanged with the air through the inclined sidewall of the heat dissipation mesh, achieving effective cooling. The cover plate shields the upper end of the heat dissipation mesh, preventing dust from falling directly in. Simultaneously, the inclined sidewall facilitates the natural falling off of adhering dust, reducing heat dissipation obstruction. By rotating the screw to disengage the hook from the fixing seat, the cover plate and heat dissipation mesh can be removed sequentially. This eliminates the need for complex operations, significantly simplifying the disassembly and cleaning process of the heat dissipation mesh and reducing maintenance difficulty. An insect-blocking rod under the cover plate surrounds the outside of the heat dissipation mesh, both maintaining gaps for heat dissipation and intercepting flying insects, dust, and cobwebs, preventing blockage of the heat dissipation mesh pores and ensuring unobstructed heat dissipation channels.

Description

Technical Field

[0001] This application relates to the field of rectifier technology, and in particular to a low-voltage winding module detachable transformer rectifier. Background Technology

[0002] As the core device for power conversion and voltage regulation, the transformer rectifier can convert AC power into DC power after stepping down or stepping up the voltage. It is widely used in electronic equipment power supplies, industrial production drive systems, and new energy power supply modules, and is an indispensable key component in power applications.

[0003] Transformer rectifiers are typically installed using nuts, a convenient method that also facilitates disassembly. Additionally, transformer rectifiers are often fitted with heat dissipation meshes for dust prevention and heat dissipation. A relevant patent, such as application number 202323626133.3, describes a transformer rectifier with dust prevention capabilities, comprising a rectifier body with a dust removal frame fixed to its top surface. A horizontally installed dustproof mesh on the upper part of the rectifier body provides dust prevention and heat dissipation.

[0004] Although the aforementioned application can achieve dust prevention and heat dissipation by installing a dustproof net on the upper part of the rectifier body, the dustproof net is directly laid flat on the upper part of the rectifier body, and the surface of the dustproof net is heavily dusty, requiring regular cleaning to avoid affecting heat dissipation, which increases labor costs.

[0005] Therefore, those skilled in the art have provided a low-voltage winding module detachable transformer rectifier to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides a low-voltage winding module detachable transformer rectifier. The heat at the upper end of the rectifier body can be exchanged with the air through the inclined side wall of the heat dissipation mesh, achieving effective cooling. The cover plate blocks the upper end of the heat dissipation mesh to prevent dust from falling in directly. At the same time, the inclined side wall facilitates the natural falling off of attached dust, reducing heat dissipation obstruction.

[0007] The low-voltage winding module detachable transformer rectifier provided in this application adopts the following technical solution:

[0008] A low-voltage winding module detachable transformer rectifier includes a rectifier body. A hollow heat dissipation mesh is detachably installed on the upper end of the rectifier body. The lower end of the heat dissipation mesh is attached to the upper end of the rectifier body. A cover plate is detachably installed on the upper end of the heat dissipation mesh. Fixing seats are fixed on both sides of the upper end of the rectifier body. Hooks are rotatably provided on both sides of the bottom end of the cover plate. The hooks are attached to the lower surface of the fixing seats. A screw is threadedly connected between the hooks and the fixing seats.

[0009] Preferably, a horizontally arranged mounting rod is fixed on the lower surface of the cover plate, a slot is provided at the upper end of the heat dissipation mesh, the mounting rod is inserted into the slot, and the upper end of the hook is rotatably connected to the end of the mounting rod.

[0010] Preferably, the heat dissipation mesh has a trapezoidal structure that is wider at the top and narrower at the bottom, and a rotating rod is rotatably connected to the upper end of the hook, and the rotating rod is rotatably connected to the end of the mounting rod.

[0011] Preferably, several vertically arranged insect-blocking rods are fixed around the lower end of the cover plate, and the lateral distance between adjacent insect-blocking rods is 0.5cm-1cm.

[0012] Preferably, a handwheel is fixedly connected to the upper end of the screw, and mounting ears are fixed on both sides of the bottom end of the rectifier body.

[0013] Preferably, a through hole is provided at the upper end of the cover plate, and a heat dissipation box communicating with the through hole is fixed at the upper end of the cover plate, and a number of heat dissipation fins are fixed through the upper end of the heat dissipation box.

[0014] In this invention, the heat dissipation box at the upper end of the cover plate is connected to the through hole of the cover plate, which can guide the heat of the rectifier into the box, and then exchange heat with the outside through the heat sink, further enhancing the heat dissipation effect at the upper end of the rectifier and avoiding heat accumulation.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. The heat at the upper end of the rectifier body of this application can be exchanged with the air through the inclined side wall of the heat dissipation mesh, so as to achieve effective cooling. The cover plate blocks the upper end of the heat dissipation mesh to prevent dust from falling in directly. At the same time, the inclined side wall facilitates the natural falling off of the attached dust, avoiding increased labor costs and reducing heat dissipation obstacles.

[0017] 2. By rotating the screw to disengage the hook from the fixing seat, the cover plate and heat dissipation mesh can be removed one by one. No complicated operation is required, which greatly simplifies the disassembly and cleaning process of the heat dissipation mesh and reduces the difficulty of maintenance.

[0018] 3. The insect-blocking rod under the cover surrounds the heat dissipation mesh, which not only leaves gaps for heat dissipation but also intercepts flying insects, dust, and cobwebs, preventing the heat dissipation mesh from becoming clogged and ensuring unobstructed heat dissipation channels.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this application discloses a low-voltage winding module detachable transformer rectifier, including a rectifier body 1. A hollow heat dissipation mesh 8 is detachably installed on the upper end of the rectifier body 1. The lower end of the heat dissipation mesh 8 is attached to the upper end of the rectifier body 1. The heat dissipation mesh 8 has a trapezoidal structure that is wider at the top and narrower at the bottom. A cover plate 7 is detachably installed on the upper end of the heat dissipation mesh 8. Fixing seats 3 are fixed on both sides of the upper end of the rectifier body 1. Hooks 4 are rotatably installed on both sides of the bottom end of the cover plate 7. The hooks 4 are attached to the lower surface of the fixing seats 3, and a screw 2 is threadedly connected between the hooks 4 and the fixing seats 3. By installing the hollow heat dissipation mesh 8 on the upper end of the rectifier and the cover plate 7 on the upper end of the heat dissipation mesh 8, heat dissipation can be effectively blocked. At the top of the heat exchanger 8, the heat from the top of the rectifier body 1 can be exchanged with the outside air through the side wall of the heat exchanger 8, thus cooling the rectifier body 1. The cover plate 7 blocks the top of the heat exchanger 8, preventing dust from falling directly onto the heat exchanger 8. The heat exchanger 8 has a trapezoidal structure, which makes the side wall of the heat exchanger 8 inclined, which is conducive to dust falling off and reduces dust adhesion on the side wall of the heat exchanger 8, avoiding increased labor costs and facilitating heat dissipation at the top of the rectifier body 1. By rotating the screw 2 upward to disengage the hook 4, the hook 4 can be rotated to disengage from the fixing seat 3, and the cover plate 7 can be moved upward to disengage the heat exchanger 8 from the top of the rectifier body 1, making it convenient to remove the heat exchanger 8 for dust removal.

[0026] A horizontally arranged mounting rod 6 is fixed on the lower surface of the cover plate 7. A slot 12 is opened at the upper end of the heat dissipation mesh 8. The mounting rod 6 is inserted into the slot 12. The upper end of the hook 4 is rotatably connected to the end of the mounting rod 6. The mounting rod 6 at the lower end of the cover plate 7 is inserted into the slot 12 at the upper end of the heat dissipation mesh 8. This not only limits the cover plate 7 on the heat dissipation mesh 8 and prevents the cover plate 7 and the heat dissipation mesh 8 from shifting, but also allows it to be fastened to the fixing seat 3 by the hook 4. The hook 4 and the fixing seat 3 are locked by the screw 2, and the cover plate 7 and the heat dissipation mesh 8 are fixedly installed together on the upper end of the rectifier body 1 for heat dissipation at the upper end of the rectifier body 1.

[0027] To support the hook 4, a rotating rod 5 is rotatably connected to the upper end of the hook 4, and the rotating rod 5 is rotatably connected to the end of the mounting rod 6.

[0028] As a specific embodiment, several vertically arranged insect-blocking rods 10 are fixed around the lower end of the cover plate 7, and the lateral distance between adjacent insect-blocking rods 10 is 0.5cm-1cm. By setting insect-blocking rods 10 around the lower surface of the cover plate 7, the insect-blocking rods 10 surround the heat dissipation net 8, and gaps are left between adjacent insect-blocking rods 10. This allows the heat from the upper end of the rectifier body 1 to pass through the heat dissipation net 8 and exchange heat with the outside air through the gaps between adjacent insect-blocking rods 10. It also intercepts some flying insects that attach to the outer surface of the heat dissipation net 8, preventing the heat dissipation net 8 from being blocked. In addition, the insect-blocking rods 10 can also intercept some dust and cobwebs.

[0029] To facilitate the rotation of the screw 2, a handwheel 11 is fixedly connected to the upper end of the screw 2, and mounting ears 9 are fixed on both sides of the bottom end of the rectifier body 1. Nuts are inserted into the mounting ears 9 to facilitate the installation and disassembly of the rectifier body 1 itself.

[0030] In this embodiment, a through hole 15 is provided at the upper end of the cover plate 7, and a heat dissipation box 13 communicating with the through hole 15 is fixed at the upper end of the cover plate 7. Several heat dissipation fins 14 are fixed at the upper end of the heat dissipation box 13. In order to prevent the heat at the upper end of the rectifier body 1 from not being dissipated in time, a heat dissipation box 13 with an open bottom is provided at the upper end of the cover plate 7. The heat dissipation box 13 is connected to the through hole 15 in the middle part of the cover plate 7. In this way, the heat at the upper end of the rectifier body 1 passes through the heat dissipation mesh 8 with the air and exchanges heat with the outside air. The heat at the upper end of the rectifier body 1 enters the heat dissipation box 13 with the air and exchanges heat with the outside air through the heat dissipation fins 14, further improving the heat dissipation efficiency of the upper end of the rectifier body 1.

[0031] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Working principle: By installing a hollow heat dissipation mesh 8 at the top of the rectifier and a cover plate 7 at the top of the heat dissipation mesh 8, the top of the heat dissipation mesh 8 can be blocked. The heat at the top of the rectifier body 1 can exchange heat with the outside air through the side wall of the heat dissipation mesh 8, so that the rectifier body 1 can dissipate heat and cool down. The cover plate 7 blocks the top of the heat dissipation mesh 8, preventing dust from falling directly onto the heat dissipation mesh 8. The heat dissipation mesh 8 has a trapezoidal structure, which makes the side wall of the heat dissipation mesh 8 inclined, which is conducive to dust falling and reduces the dust adhesion on the side wall of the heat dissipation mesh 8, which is conducive to heat dissipation at the top of the rectifier body 1.
