Technical Field

[0001] This utility model relates to the field of power adapter housing technology, specifically a dual-channel independent heat dissipation power adapter housing. Background Technology

[0002] A power adapter is a power conversion device for small portable electronic devices and appliances. It is generally composed of components such as a casing, transformer, inductor, capacitor, control IC, and PCB board. Its working principle is to convert AC input to DC output. According to the connection method, it can be divided into wall plug type and desktop type.

[0003] Existing power adapters typically dissipate heat by setting simple ventilation holes on the casing.

[0004] However, existing power adapters use simple ventilation holes for heat dissipation, which makes it difficult for internal heat to dissipate to the outside, resulting in poor heat dissipation and affecting the use of the power adapter. To address the above problems, a dual-channel independent heat dissipation power adapter housing is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a dual-channel independent heat dissipation power adapter housing, which solves the problem in the background technology that the heat dissipation effect of the power adapter is poor because the heat inside is not easy to dissipate to the outside due to the use of simple heat dissipation holes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dual-channel independent heat dissipation power adapter housing, including an outer shell, a cover on the top of the outer shell, a partition fixedly connected between the inner walls of the outer shell, two fans penetrating and fixedly connected to one side of the outer wall of the outer shell, heat dissipation fins penetrating and provided at the bottom of the outer wall of the outer shell, two fixed shells fixedly connected to the left side of the outer wall of the outer shell, slots opened on the top of the outer walls of the two fixed shells, filters slidably connected to the inner walls of the two slots, limit blocks penetrating and fixedly connected to the center of the top of the outer walls of the two fixed shells, fixed plates fixedly connected to the top of the two limit blocks, telescopic rods penetrating and slidably connected to one side of the two fixed plates, square plates fixedly connected to the lower center of the outer ring of the two telescopic rods, first springs sleeved on the upper center of the outer ring of the two telescopic rods, pressure plates fixedly connected to the top of the outer ring of the two telescopic rods, connecting blocks fixedly connected to the bottom of the two pressure plates, pointers fixedly connected to one side of the outer ring of the two telescopic rods, and a disassembly assembly provided at the bottom of the cover.

[0007] By adopting the above technical solution, starting two fans can blow cold air into the casing, filter it through the filter screen, and then hot air flows out from the ventilation cover, where the heat dissipation fins below work together to dissipate heat.

[0008] As a further description of the above technical solution: the disassembly assembly includes two insert plates, which are fixedly connected to the cover. Two placement slots are opened on the top of the outer shell. Two support rods are slidably connected through the front and rear sides of the outer wall of the outer shell. A female locking block is fixedly connected to one end of each of the two adjacent support rods. A second spring is sleeved on the outer ring of each of the two adjacent support rods. A second protrusion is fixedly connected to the other end of each of the two adjacent support rods. A female locking block is fixedly connected to the front and rear sides of each of the two insert plates.

[0009] By adopting the above technical solution, the disassembly components facilitate the removal of the cover for maintenance of the interior of the casing.

[0010] As a further description of the above technical solution: two ventilation covers are threadedly connected to the left side of the outer wall of the housing.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model provides a dual-channel independent heat dissipation power adapter housing. Through a filter screen, heat dissipation fins, fans, telescopic rods, and a square plate, starting two fans blows cold air into the housing, which is filtered by the filter screen. Then, hot air flows out from the ventilation cover, and the heat dissipation fins below work together to dissipate heat. Then, pulling the telescopic rod moves the square plate from the square slot and compresses the first spring, which then drives the pressure plate to rotate, thus releasing the filter screen from its limiting position and allowing it to slide downwards for replacement. This improves the heat dissipation effect and facilitates filter maintenance.

[0024] 2. The present invention provides a dual-channel independent heat dissipation power adapter housing, which consists of a cover, a sub-block, a plug plate, a female block, and a support rod. Pulling the second protrusion causes the support rod to move, and then the second spring is compressed, releasing the female block from its limiting position on the sub-block. After that, the plug plate can be removed from the placement slot, and then the cover can be removed for internal maintenance. When installation is required, simply place the cover on top of the housing, press the cover, and the sub-block and female block will engage to fix the cover, making maintenance convenient.

The partition 27 is placed inside the outer shell 1 to form a dual channel for accommodating different components. Two ventilation covers 5 are threadedly connected to the left side of the outer wall of the outer shell 1. The ventilation covers 5 can be removed for cleaning by rotating them. The bottom of the inner wall of each of the two limiting blocks 15 has a square groove 16. When the square block 11 is inserted into the square groove 16, it can be positioned and the pressure plate 13 can be fixed. The inner wall of the square groove 16 is slidably connected. There is a square plate 11, and a circular scale 17 is fixedly connected to the top of the fixed plate 9. When the pressure plate 13 rotates, the pointer 18 is locked and rotates with it, and moves on the circular scale 17 to make it easy to see how many degrees it has moved. The pointer 18 is set on the top of the circular scale 17. The insert plate 4 is slidably connected to the inner wall of the placement groove 26. The sub-clamp block 21 is slidably connected to the inner wall of the placement groove 26. When the sub-clamp block 21 and the female clamp block 20 are engaged, the cover 2 can be fixed. The sub-clamp block 21 and the female clamp block 20 are engaged. The top of the telescopic rod 10 is fixedly connected to the first protrusion 19. The bottom of the connecting block 14 is provided with a filter screen 7.

[0035] Combination Figures 2-5Two fans 6 are connected and fixedly connected to one side of the outer wall of the outer casing 1. Heat dissipation fins 24 are provided and installed through the bottom of the outer wall of the outer casing 1, which can assist in heat dissipation during the cooling process. Two fixed shells 3 are fixedly connected to the left side of the outer wall of the outer casing 1. Slots 8 are provided on the top of the outer walls of both fixed shells 3. Filters 7 are slidably connected to the inner walls of both slots 8. When cold air from the outside enters, it will first pass through the filters 7, reducing the entry of dust. Limiting blocks 15 are connected and fixedly connected through the center of the top of the outer walls of both fixed shells 3. Fixing plates 9 are fixedly connected to the top of both limiting blocks 15. One side of each fixing plate 9 is connected and slidably connected... There is a telescopic rod 10. When the first protrusion 19 is pulled, the telescopic rod 10 can be extended and retracted, and then the square block 11 moves from the square groove 16 and presses the spring 12. Square plates 11 are fixedly connected to the lower center of the outer ring of the two telescopic rods 10. The first spring 12 is sleeved on the upper center of the outer ring of the two telescopic rods 10. Pressure plates 13 are fixedly connected to the top of the outer ring of the two telescopic rods 10. Rotating the pressure plates 13 can release the restriction on the filter screen 7, making it easy to replace. Connecting blocks 14 are fixedly connected to the bottom of the two pressure plates 13. Pointers 18 are fixedly connected to one side of the outer ring of the two telescopic rods 10. A disassembly component is provided at the bottom of the cover 2.

[0036] Combination Figure 6 The disassembly assembly includes two insert plates 4, which are fixedly connected to the cover 2. The top of the outer shell 1 has two placement slots 26. The insert plates 4 are inserted into the placement slots 26 for installation and positioning. The outer walls of the outer shell 1 are connected to two support rods 22 through and slidingly. When the support rods 22 are subjected to force, they can drive the female locking block 20 to move and then release the limiting position of the female locking block 21. The female locking block 20 is fixedly connected to one end of each of the two adjacent support rods 22. The outer ring of each of the two adjacent support rods 22 is fitted with a second spring 23. When the support rods 22 move, they will compress the second spring 23. The other end of each of the two adjacent support rods 22 is fixedly connected to a second protrusion 25. The female locking blocks 21 are fixedly connected to the front and rear sides of the two insert plates 4.

[0037] Working principle: During use, the shell 1 has a partition 27 inside, creating a dual-channel system with two independent heat dissipation mechanisms. When the fan 6 is started, cool outside air enters the shell 1, is filtered by the filter 7, and then the heat from the dual channels is dissipated through the ventilation cover 5. The ventilation cover 5 can be rotated to remove it for maintenance. The heat dissipation fins 24 at the bottom of the shell 1 work together to improve heat dissipation. When maintenance of the filter 7 is needed, the first protrusion 19 can be pulled to extend or retract the telescopic rod 10, allowing the square plate 11 to move from the square groove 16 and compress the first spring 12. Then, the pressure plate 13 is rotated, and the pointer 18 on the first protrusion... Sliding block 19 releases the pressure plate 13 from its limiting position on filter 7, allowing filter 7 to slide upwards for easy replacement. When maintenance of the interior of the outer casing 1 is required, the second protrusion 25 is pulled to move the support rod 22, releasing the female locking block 20 from its limiting position on the male locking block 21, allowing the cover 2 to be removed for internal maintenance. After maintenance, insert the insert plate 4 into the placement slot 26 and press down on the cover 2, causing the male locking block 21 to press against the female locking block 20, compressing the second spring 23. When the male locking block 21 moves to the other side of the female locking block 20, the second spring 23 rebounds, causing the male locking block 21 to engage with the female locking block 20 for secure fixation, facilitating maintenance and making it easy to use.
