Abstract
Description
Technical Field
[0001] This utility model relates to the field of charger technology, and in particular to a high-frequency charger with a honeycomb heat dissipation structure. Background Technology
[0002] With the widespread use of electronic devices, the demand for high-frequency chargers is increasing. High-frequency chargers hold an important position in the market due to their small size, light weight, and high charging efficiency. However, high-frequency chargers generate a lot of heat during operation. If this heat cannot be dissipated in time, the temperature of the internal components of the charger will rise, affecting the charger's performance and lifespan, and even causing safety hazards.
[0003] However, in the existing technology, the common heat dissipation methods of high-frequency chargers mainly include natural heat dissipation and forced heat dissipation. Natural heat dissipation is achieved through heat exchange between the charger shell and the air. However, this method has low heat dissipation efficiency and is difficult to meet the heat dissipation requirements of high-frequency chargers when operating at high power. Forced heat dissipation usually uses devices such as fans to accelerate airflow. Although it can improve heat dissipation efficiency to a certain extent, it will increase the size and weight of the charger. Utility Model Content
[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a high-frequency charger with a honeycomb heat dissipation structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-frequency charger with a honeycomb heat dissipation structure, comprising a high-frequency charger body and a high-frequency charging circuit module, wherein a honeycomb heat dissipation mechanism is provided at the rear end of the high-frequency charger body, a filter plate is provided at one end of the honeycomb heat dissipation mechanism, and a quick-release mechanism is provided on one side of the filter plate.
[0006] The honeycomb heat dissipation mechanism includes heat dissipation fins. A frame is installed through the rear end of the high-frequency charger body. A flow guide plate is provided on the inner side wall of the high-frequency charger body. A detachable honeycomb heat dissipation hole group is installed at one end of the frame. Multiple sets of flow guide grooves are opened at one end of the flow guide plate. Multiple sets of flow guide holes are opened through the inner wall of each set of flow guide grooves.
[0007] Preferably, multiple sets of support columns are fixedly installed on both the upper and lower ends of the outer wall of the guide plate, and one end of the heat dissipation fin is fixed to the other end of the guide plate.
[0008] Preferably, the other end of the heat dissipation fins is in contact with one side of the high-frequency charging circuit module, and one end of the multiple sets of support columns is fixed to the bottom and top of the high-frequency charger body, respectively.

Multiple sets of limiting grooves are provided at the upper and lower ends of the frame. Two sets of tension springs are fixedly installed inside the two sets of long blocks. Movable push rods are slidably installed inside the two sets of long blocks near the upper and lower ends. Multiple sets of limiting rods are fixedly installed at one end of the two sets of irregularly shaped plates.
[0010] Preferably, one end of each of the two sets of elongated blocks is fixed to the other end of the filter screen, and the other ends of the four sets of tension springs are respectively fixed to one end of each of the four sets of movable push rods.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1.

[0015] 2. The quick-installation mechanism in this utility model enables the rapid installation and removal of the filter screen without the need for tools.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a high-frequency charger with a honeycomb heat dissipation structure, including a high-frequency charger body 1 and a high-frequency charging circuit module 13. A honeycomb heat dissipation mechanism 2 is provided at the rear end of the high-frequency charger body 1. A filter screen plate 12 is provided at one end of the honeycomb heat dissipation mechanism 2. A quick-installation mechanism 3 is provided on one side of the filter screen plate 12. An elliptical mesh plate 11 is provided through one side of the high-frequency charger body 1. A small fan 14 is installed through the other side of the high-frequency charger body 1.
[0024] The honeycomb heat dissipation mechanism 2 includes heat dissipation fins 22. A frame 21 is installed through the rear end of the high-frequency charger body 1. A guide plate 23 is provided on the inner side wall of the high-frequency charger body 1. A detachable honeycomb heat dissipation hole group 25 is installed at one end of the frame 21. Multiple sets of guide grooves 26 are opened at one end of the guide plate 23. Multiple sets of guide holes 27 are opened through the inner wall of the multiple sets of guide grooves 26. Multiple sets of support columns 24 are fixedly installed at the upper and lower ends of the outer wall of the guide plate 23. One end of the heat dissipation fin 22 is fixed to the other end of the guide plate 23. The other end of the heat dissipation fin 22 is in contact with one side of the high-frequency charging circuit module 13. One end of the multiple sets of support columns 24 is fixed to the inner bottom and top of the high-frequency charger body 1, respectively. The high-frequency charging circuit module 13 is fixedly installed inside the high-frequency charger body 1.
[0025] The specific settings and functions of this embodiment are described in detail below. The frame 21 adopts a metal frame structure, possessing high strength and heat dissipation performance. The frame 21 is installed through the rear end of the high-frequency charger body 1 and is fixedly connected to the charger body with screws to ensure stable installation. One end of the frame 21 is provided with a mounting slot for a detachable honeycomb-shaped heat dissipation hole assembly 25. The slot adopts a snap-on design, facilitating quick installation and removal of the honeycomb-shaped heat dissipation hole assembly 25. The other end cooperates with the guide plate 23 inside the charger body to form a complete heat dissipation channel. The guide plate 23 is made of aluminum alloy, possessing good thermal conductivity and lightweight characteristics. The plate is flat, with one end of the guide plate 23... Multiple sets of airflow guide channels 26 are provided. The shape and size of the airflow guide channels 26 have been optimized by fluid dynamics simulation to effectively guide airflow. Multiple sets of airflow guide holes 27 are provided through the inner wall of each set of airflow guide channels 26. The diameter of the airflow guide holes 27 matches the heat dissipation holes of the honeycomb heat dissipation hole group 25 and is arranged in a regular manner to ensure that the air can pass through evenly and smoothly. Multiple sets of support columns 24 are fixedly installed at the upper and lower ends of the outer wall of the airflow guide plate 23. The support columns 24 are made of high-strength plastic material, and the other end is fixed to the bottom and top of the high-frequency charger body 1 respectively, so as to firmly support the airflow guide plate 23 inside the charger and form an airflow channel between the airflow guide plate 23 and the side wall of the charger body.
[0026] The heat dissipation fins 22 are made of high-purity aluminum and are made into a wave-shaped structure through a stamping process to increase the contact area with air. The fin thickness has been optimized to reduce the overall weight while ensuring good thermal conductivity.
[0027] One end of the heat dissipation fin 22 is firmly bonded to the other end of the guide plate 23 via thermally conductive silicone to ensure rapid heat conduction; the other end is tightly attached to one side of the high-frequency charging circuit module 13, quickly absorbing and transferring the heat generated by the circuit module to the guide plate 23. The honeycomb heat dissipation hole group 25 is composed of multiple hexagonal heat dissipation hole units. Adjacent hexagonal heat dissipation hole units share sides, forming a honeycomb-shaped tightly arranged structure. This structure has the largest heat dissipation surface area per unit area and has good mechanical properties, and can withstand a certain amount of external impact. It is connected to the mounting slot of the frame 21 by a buckle, which facilitates disassembly for cleaning and maintenance, ensuring unobstructed heat dissipation holes and maintaining good heat dissipation effect.
[0028] The small fan 14 provides sufficient airflow to accelerate air circulation inside the charger. The small fan 14 and the elliptical mesh plate 11 work together to force airflow and create convection. The elliptical mesh plate 11 optimizes the air intake path and improves heat dissipation speed. The filter plate 12 blocks dust from entering the charger, preventing dust accumulation on components from affecting performance and extending service life. The support column 24 evenly fixes the air guide plate 23 to ensure the stability of the heat dissipation channel structure, while preventing the air guide plate 23 from directly contacting the honeycomb heat dissipation hole group to ensure smooth airflow.
[0029] Example 2: Figure 1 , Figure 3 and Figure 4 As shown, the quick-installation mechanism 3 includes a long block 31 and two sets of irregularly shaped plates 33. Multiple sets of limiting grooves 32 are opened at the upper and lower ends of the frame 21. Two sets of tension springs 34 are fixedly installed inside the two sets of long blocks 31. Movable push rods 35 are slidably installed inside the two sets of long blocks 31 near the upper and lower ends. Multiple sets of limiting rods 36 are fixedly installed at one end of the two sets of irregularly shaped plates 33. One end of the two sets of long blocks 31 is fixed to the other end of the filter screen plate 12. The other ends of the four sets of tension springs 34 are respectively fixed to one end of the four sets of movable push rods 35. The long rods of the four sets of movable push rods 35 pass through the upper and lower ends of the two sets of long blocks 31 and are respectively fixed to one end of the two sets of irregularly shaped plates 33. Multiple sets of limiting rods 36 are respectively inserted into the interior of multiple sets of limiting grooves 32.
[0030] The overall effect of this embodiment is that the two sets of long blocks 31 are made of high-strength plastic material with a hollow internal design. Each set has two sets of tension springs 34 fixedly installed inside, and the tension springs 34 have good elasticity and durability. Movable push rods 35 are slidably installed inside and near the top and bottom ends. The movable push rods 35 can slide freely inside the long blocks 31. The two sets of irregular plates 33 are made of metal material, and multiple sets of limiting rods 36 are fixedly installed at one end. The shape and size of the limiting rods 36 match the limiting grooves 32 on the frame 21. The irregular plates 33 are connected to the long blocks 31 through the movable push rods 35. Under the action of the tension springs 34, the limiting rods 36 can be extended and retracted.
[0031] When the filter screen 12 needs to be installed, pull the two sets of irregularly shaped plates 33, so that they drive the four sets of tension springs 34 to extend outward through the four sets of movable push rods 35, aligning the filter screen 12 with the frame 21. Release the two sets of irregularly shaped plates 33. Under the tension of the four sets of tension springs 34, the four sets of tension springs 34 drive the two sets of irregularly shaped plates 33 to move through the four sets of movable push rods 35. The two sets of irregularly shaped plates 33 drive the multiple sets of limiting rods 36 to move, so that the limiting rods 36 are inserted into the limiting grooves 32, completing the quick installation of the filter screen 12. When disassembling, simply pull the two sets of irregularly shaped plates 33, so that they drive the multiple sets of limiting rods 36 from inside the limiting grooves 32, and the filter screen 12 can be easily removed.
[0032] The usage and working principle of this device: When the high-frequency charger is connected to the power supply and starts working, the high-frequency charging circuit module 13 converts the input electrical energy into charging electrical energy suitable for electronic devices through high-frequency switching power supply technology. During this electrical energy conversion process, the circuit components will generate a lot of heat. If it is not dissipated in time, it will seriously affect the performance and service life of the charger.
[0033] Then, heat is first generated from the high-frequency charging circuit module 13. Because it is closely attached to the heat sink fins 22, the heat is quickly transferred to the heat sink fins 22 under the action of heat conduction. The heat sink fins 22 are made of high-purity aluminum and have a wave-shaped structure, which greatly increases the contact area with the air and changes the direction of air flow. At this time, the small fan 14 starts to play a role in accelerating the air flow. The incoming air flows through the internal space of the charger to the guide plate 23 under the action of the small fan 14. The guide grooves 26 and guide holes 27 of the guide plate 23 are optimized by fluid dynamics simulation, which can effectively guide the orderly flow of air and make the air pass through evenly and smoothly. When the air flows through the heat sink fins 22, it fully contacts the surface of the fins and takes away the heat on the fins, realizing heat exchange.
[0034] Finally, the air carrying heat enters the flow channel between the flow guide plate 23 and the side wall of the high-frequency charger body 1 through the flow guide hole 27 of the flow guide plate 23. The flow channel guides the air to flow to the honeycomb heat dissipation hole group 25. The honeycomb heat dissipation hole group 25 is composed of multiple hexagonal heat dissipation hole units arranged closely together. This structure has the largest heat dissipation surface area per unit area and can efficiently dissipate heat to the external environment.
[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
