Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, specifically a power adapter with air-cooling function. Background Technology

[0002] With the widespread use of electronic devices, power adapters, as key power supply components connecting the power grid and electronic devices, have become indispensable accessories for various electronic devices such as laptops, printers, and routers. Their core function is to convert AC power from the mains into DC power required by electronic devices and to stabilize the output voltage and current to ensure the normal operation of the devices.

[0003] As electronic devices develop towards high performance and miniaturization, the power density requirements for power adapters are also constantly increasing. When achieving high power output within a limited volume, the electronic components inside the adapter, such as transformers, rectifier bridges, and capacitors, will generate a lot of heat during operation. However, traditional power adapters mostly adopt passive heat dissipation methods, that is, they rely solely on the heat conduction of the casing itself and natural convection for heat dissipation. The heat dissipation efficiency is low, and it is difficult to quickly dissipate the heat accumulated inside.

[0004] According to the patent application published on the Internet, a power adapter with air cooling function (authorization announcement number: CN216312926U) includes "adapter body, fixing rod" etc., to achieve heat dissipation.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This power adapter with air cooling function uses the adapter body and fixing rod to achieve heat dissipation. When in use, the adapter works by rotating blades to expel heat through the air outlet. However, there is no filtration at the air inlet and outlet, which causes external dust to enter the adapter body and accumulate, affecting the safety of use. Moreover, the single air cooling effect is poor. Therefore, this adapter needs to be improved. Utility Model Content

[0007] The purpose of this invention is to provide a power adapter with air-cooled heat dissipation function to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a power adapter with air-cooled heat dissipation function, including a plug, a heat dissipation mechanism is provided on the top of the plug, a fixing mechanism is provided on the front and rear sides of the heat dissipation mechanism, and a connecting wire is provided inside the heat dissipation mechanism;

[0009] The heat dissipation mechanism includes a lower housing, which is fixedly connected to the top of the plug. An upper housing is inserted into the top of the lower housing. A first protective frame is slidably connected to the periphery of the lower housing. Lower sealing strips are fixedly connected to the top of the front and rear sides of the first protective frame. A first heat sink is fixedly connected to the bottom of the first protective frame. A second protective frame is slidably connected to the periphery of the upper housing. Upper sealing strips are fixedly connected to the bottom of the front and rear sides of the second protective frame. The upper sealing strips are positioned on top of the lower sealing strips. A second heat sink is fixedly connected to the top of the second protective frame. A mounting base is fixedly connected to the bottom of the lower housing. A fan is slidably connected inside the mounting base. Guide shafts are fixedly connected to the front and rear sides of the fan. The guide shafts are slidably connected inside the mounting base.

[0010] Preferably, the lower housing and the upper housing are provided with air inlet and air outlet on the left and right sides respectively, and both are rectangular. The upper housing is slidably connected to the periphery of the fan, so that heat dissipation can be achieved through the air inlet and air outlet.

[0011] Preferably, the bottom of the first protective frame is in contact with the bottom of the lower housing, the top of the second protective frame is in contact with the top of the upper housing, the bottom of the upper sealing strip is in contact with the top of the lower sealing strip, and the upper and lower sealing strips are located on the periphery of the contact surface between the lower and upper housings, so that the contact position between the lower and upper housings can be sealed by the two sealing strips.

[0012] Preferably, the first protective frame and the second protective frame are slidably connected to the periphery of the connecting line, and the bottom of the first protective frame and the top of the second protective frame are made of aluminum alloy, so that the lower shell and the periphery of the upper shell can be protected through the first protective frame and the second protective frame.

[0013] Preferably, the first and second protective frames are provided with filter holes on their left and right sides, and both are circular. The filter holes are connected to the air inlet and air outlet, so that the incoming air can be filtered through the filter holes.

[0014] Preferably, the fixing mechanism includes a connecting frame, which is slidably connected to the periphery of the lower sealing strip and the upper sealing strip. An insert rod is fixedly connected to the inner side of the connecting frame, and the insert rod is inserted into the interior of the lower sealing strip and the upper sealing strip. A fixing shaft is threadedly connected to the inside of the connecting frame.

[0015] Preferably, the fixed shaft passes through the interior of the lower sealing strip and the upper sealing strip, and the insert rod passes through the interior of the lower housing and the upper housing. The connecting frame, the insert rod and the fixed shaft are provided in two sets and are symmetrically distributed on the front and rear sides of the lower housing. By providing two sets, the stability between the lower housing and the upper housing can be ensured.

[0016] Compared with the prior art, this utility model provides a power adapter with air-cooling function, which has the following beneficial effects:

[0017] 1. This power adapter with air-cooled heat dissipation function utilizes a cooling mechanism. A fan fixed at the bottom of the lower housing actively draws in air, which enters through the air inlets on the right side of the lower and upper housings. After exchanging heat with the internal components, the air is exhausted through the air outlet on the left side, forming an airflow channel to quickly remove internal heat. Simultaneously, the first heat sink at the bottom of the first protective frame and the second heat sink at the top of the second protective frame further conduct heat away from the adapter surface. This dual cooling method effectively reduces the adapter's operating temperature, preventing performance degradation and shortened lifespan due to overheating. The plug-in structure of the lower and upper housings, as well as the sliding wrapping design of the first and second protective frames, effectively prevent external dust and impurities from entering the adapter, reducing dust accumulation and damage to internal components, and lowering the failure rate. The lower sealing strips on the top of the front and rear sides of the first protective frame and the upper sealing strips on the bottom of the front and rear sides of the second protective frame contact each other and are located on the periphery of the contact surface between the lower and upper housings, forming a good sealing structure. This not only prevents dust from entering but also blocks moisture splashing in to a certain extent, improving the adapter's dustproof and waterproof performance and enhancing product safety.

[0018] 2. This power adapter with air-cooled heat dissipation function, through a fixed mechanism, has a connecting frame that slides around the lower and upper sealing strips. It is inserted into the lower and upper sealing strips, as well as the lower and upper housings, through a plug rod. With the threaded connection of the fixed shaft, the lower housing, upper housing, first protective frame, and second protective frame are firmly fixed together, preventing the components from loosening or shifting during use. It also facilitates installation and disassembly, improving the convenience of use. Attached Figure Description

[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Please see Figure 1-5 This utility model provides a technical solution: a power adapter with air cooling function, including a plug 1, a heat dissipation mechanism 2 is provided on the top of the plug 1, a fixing mechanism 3 is provided on the front and rear sides of the heat dissipation mechanism 2, and a connecting wire 4 is provided inside the heat dissipation mechanism 2.

[0031] The heat dissipation mechanism 2 includes a lower housing 21, which is fixedly connected to the top of the plug 1. An upper housing 22 is inserted into the top of the lower housing 21. A first protective frame 23 is slidably connected to the periphery of the lower housing 21. A lower sealing strip 24 is fixedly connected to the top of the front and rear sides of the first protective frame 23. A first heat sink 25 is fixedly connected to the bottom of the first protective frame 23. A second protective frame 26 is slidably connected to the periphery of the upper housing 22. An upper sealing strip 27 is fixedly connected to the bottom of the front and rear sides of the second protective frame 26. The upper sealing strip 27 is located on top of the lower sealing strip 24. A second heat sink 28 is fixedly connected to the top of the second protective frame 26. A mounting base 29 is fixedly connected to the bottom inside the lower housing 21. A fan 291 is slidably connected inside the mounting base 29. A guide shaft 292 is fixedly connected to the front and rear sides of the fan 291. The guide shaft 292 is slidably connected inside the mounting base 29.

[0032] The lower housing 21 and the upper housing 22 have air inlet and air outlet openings on their left and right sides, respectively, and both are rectangular. The upper housing 22 is slidably connected to the periphery of the fan 291, so that heat dissipation can be achieved through the air inlet and air outlet openings.

[0033] The bottom of the first protective frame 23 is in contact with the bottom of the lower housing 21, the top of the second protective frame 26 is in contact with the top of the upper housing 22, the bottom of the upper sealing strip 27 is in contact with the top of the lower sealing strip 24, and the upper sealing strip 27 and the lower sealing strip 24 are located on the periphery of the contact surface between the lower housing 21 and the upper housing 22, so that the contact position between the lower housing 21 and the upper housing 22 can be sealed by the two sealing strips.

[0034] The first protective frame 23 and the second protective frame 26 are slidably connected to the periphery of the connecting line 4. The bottom of the first protective frame 23 and the top of the second protective frame 26 are made of aluminum alloy, which makes it easy to protect the periphery of the lower shell 21 and the upper shell 22 through the first protective frame 23 and the second protective frame 26.

[0035] The first protective frame 23 and the second protective frame 26 have filter holes on their left and right sides, and both are circular. The filter holes are connected to the air inlet and air outlet, so that the incoming air can be filtered through the filter holes.

[0036] Example 2

[0037] Please see Figure 1-5 Furthermore, based on Embodiment 1, the fixing mechanism 3 includes a connecting frame 31, which is slidably connected to the periphery of the lower sealing strip 24 and the upper sealing strip 27. An insert rod 32 is fixedly connected to the inner side of the connecting frame 31, and the insert rod 32 is inserted into the interior of the lower sealing strip 24 and the upper sealing strip 27. A fixing shaft 33 is threadedly connected inside the connecting frame 31.

[0038] The fixed shaft 33 passes through the interior of the lower sealing strip 24 and the upper sealing strip 27, and the insert rod 32 passes through the interior of the lower housing 21 and the upper housing 22. The connecting frame 31, the insert rod 32 and the fixed shaft 33 are provided in two sets and are symmetrically distributed on the front and rear sides of the lower housing 21. By setting two sets, the stability between the lower housing 21 and the upper housing 22 can be guaranteed.

[0039] In actual operation, when this device is used, firstly, the fan 291 is slidably connected to the inside of the mounting base 29, so that the fan 291 drives the guide shaft 292 to be slidably connected to the inside of the mounting base 29. The upper housing 22 is inserted into the top of the lower housing 21 and slidably connected to the outside of the fan 291. At the same time, the first protective frame 23 is slidably connected to the outside of the lower housing 21, so that the bottom of the first protective frame 23 is in contact with the bottom of the lower housing 21. The second protective frame 26 is slidably connected to the outside of the upper housing 22, so that the top of the second protective frame 26 is in contact with the top of the upper housing 22.

[0040] Once installation is complete, the connecting frame 31 can be slidably connected to the periphery of the lower sealing strip 24 and the upper sealing strip 27. The insert rod 32 is inserted into the lower sealing strip 24, the upper sealing strip 27, and the interior of the lower housing 21 and the upper housing 22. With the threaded connection of the fixing shaft 33, the lower housing 21, the upper housing 22, the first protective frame 23, and the second protective frame 26 are firmly fixed together to prevent the components from loosening or shifting during use. At the same time, it facilitates installation and disassembly, improving the convenience of use.

[0041] The fan 291 fixed at the bottom of the lower housing 21 can actively draw in air. The air enters through the air inlet on the right side of the lower housing 21 and the upper housing 22, exchanges heat with the internal components of the adapter, and then is discharged from the air outlet on the left side, forming an air circulation channel to quickly remove internal heat. At the same time, the first heat sink 25 at the bottom of the first protective frame 23 and the second heat sink 28 at the top of the second protective frame 26 can further conduct heat away from the surface of the adapter. The dual heat dissipation method effectively reduces the operating temperature of the adapter and avoids problems such as performance degradation and shortened service life caused by overheating.

[0042] When outside air enters the housing, it can be filtered by the filter holes on the left and right sides of the first protective frame 23 and the second protective frame 26, which can effectively block external dust and impurities from entering the adapter, reduce the damage of dust accumulation to internal components, and reduce the failure rate. The lower sealing strip 24 on the top of the front and rear sides of the first protective frame 23 and the upper sealing strip 27 on the bottom of the front and rear sides of the second protective frame 26 are in contact with each other and are located on the periphery of the contact surface between the lower housing 21 and the upper housing 22, forming a good sealing structure. This not only prevents dust from entering, but also blocks water splashing in to a certain extent, improving the dustproof and waterproof performance of the adapter and enhancing the safety of product use.

[0043] When in use, the fan 291 needs to be connected to the electrical components inside the upper housing 22 and the lower housing 21 to provide power.
