Therefore, an existing power adapter with a heat dissipation structure has been continuously innovated and developed. It can be seen that the current power adapter with a heat dissipation structure basically meets people's needs, but there are still some problems.

The utility model is provided with a support plate and a fan. After the support plate is turned over, it can stably support the power adapter in cooperation with the inclined feet, so that the power adapter is in a suspended state, which is beneficial to the heat dissipation of the power adapter. At the same time, after the set fan operates, the heated electrical components are dissipated by the wind force, so that the electrical components can be at a lower temperature".

[0004] However, when the above device is actually used, a plurality of exhaust holes facilitate the discharge of the hot air flow passing through the heated electrical components. Due to the opening of the exhaust holes, the inside of the adapter housing main body is permeable, and the water mist and dust in the outside world can enter the inside of the adapter housing main body through the exhaust holes, thereby damaging the power adapter main body and reducing the practicability of the device. Therefore, there is an urgent need for a power adapter with a heat dissipation structure to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a power adapter with a heat dissipation structure to solve the problem that in the process of use, due to the opening of the exhaust holes, the water mist and dust in the outside world can pass through the adapter housing main body, thereby damaging the power adapter main body as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution. A power adapter with a heat dissipation structure is disclosed, which includes a housing, a support frame is fixedly installed on the inner wall of the housing, and a fixed block is arranged at the bottom of the housing;

[0007] The first heat sink; the first heat sink is fixedly connected to the inner wall of the support frame, a heat-conducting glue is applied to the outer surface of the first heat sink, and the heat-conducting glue overlaps the inner wall of the support frame.

[0009] Preferably, a filter screen is arranged on the inner wall of the housing, and the filter screen overlaps the outer surface of the cooling fan.

[0010] Preferably, an adapter body is arranged on the inner wall of the housing, and a connection socket is opened on one side of the housing.

[0011] Preferably, a power-on wire is connected to one side of the housing, and a cable tie is arranged on the outer surface of the power-on wire.

[0012] Preferably, anti-slip patterns are arranged at the bottom of the fixing block, and there are two fixing blocks.

[0013] Preferably, the second heat sink is in a U-shaped block shape, and the heat-conducting glue is applied to one side of the second heat sink.

[0014] Preferably, there are two groups of cooling fans, and the cooling fans are arranged above the ventilation holes.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present utility model:

[0026] It includes a housing 1, a support frame 2 is fixedly installed on the inner wall of the housing 1, a fixing block 3 is arranged at the bottom of the housing 1, and a first heat sink 4; the first heat sink 4 is fixedly connected to the inner wall of the support frame 2, a heat-conducting glue 5 is applied on the outer surface of the first heat sink 4, and the heat-conducting glue 5 overlaps the inner wall of the support frame 2. A cooling fan 6 is arranged on the inner wall of the housing 1, and the cooling fan 6 is fixedly connected to the inner wall of the support frame 2. Two groups of side-by-side ventilation holes 7 are opened at the bottom of the housing 1. Anti-slip patterns 15 are arranged at the bottom of the fixing block 3, and there are two fixing blocks 3. The cooling fans 6 are in two groups and are arranged above the ventilation holes 7;

[0027] During the use of the power adapter, the adapter body 11 generates heat during operation. The heat generated by the adapter body 11 is transferred to the first heat sink 4 and the second heat sink 9 through the heat-conducting glue 5. The first heat sink 4 and the second heat sink 9 are used to dissipate the heat into the surrounding air. By turning on the cooling fan 6, the wind is used to dissipate the heat of the heated first heat sink 4 and the second heat sink 9, and the heat is discharged through the ventilation holes 7. And two cooling fans 6 are provided, which improves the heat dissipation efficiency, reduces the phenomenon of the power adapter generating heat, prolongs the service life of the power adapter. At the same time, since the first heat sink 4 overlaps the motor of the cooling fan 6, the heat generated by the operation of the motor of the cooling fan 6 can be conducted to the first heat sink 4 and then dissipated. And the power adapter is supported by the fixing block 3, so that the power adapter is in a suspended state, which is beneficial to the heat dissipation of the power adapter, and the anti-slip patterns 15 can increase the friction between the fixing block 3 and the bearing surface, thus stabilizing the power adapter.

[0028] Further, an adapter body 11 is arranged on the inner wall of the housing 1. A connection socket 12 is opened on one side of the housing 1. An energized wire 13 is connected to one side of the housing 1. A cable tie 14 is arranged on the outer surface of the energized wire 13; the energized wire 13 can be sorted out through the cable tie 14.

[0029] Please refer to Figure 2 、 Figure 3 and Figure 5 For an embodiment provided by the present utility model:

[0030] Grooves 8 are opened on both sides of the support frame 2. A second heat sink 9 is fitted and connected to the inner wall of the groove 8, and the second heat sink 9 overlaps the inner wall of the housing 1. The second heat sink 9 is in a U-shaped block shape, and the heat-conducting glue 5 is applied to one side of the second heat sink 9;

[0031] When the second heat sink 9 is damaged, by opening the housing 1, the two support frames 2 move away from each other along with the housing 1, and then the housing 1 at the bottom is inverted, and the second heat sink 9 slides out of the groove 8 of the support frame 2 under the action of gravity, which is convenient for replacement and repair.

[0032] Furthermore, a filter screen 10 is provided on the inner wall of the outer shell 1, and the filter screen 10 is lapped on the outer surface of the cooling fan 6;

[0033] The filter screen 10 can play a role in dust prevention, avoiding the problem that external dust enters the outer shell 1 through the ventilation holes 7 and affects the use of the adapter body 11.

[0034] Working principle: When using the power adapter, the adapter body 11 generates heat during operation, and the thermal conductive adhesive 5 transfers the heat to the first heat sink 4 and the second heat sink 9. Then, the heat is dissipated into the surrounding air by using the characteristics of the heat sinks themselves, playing a role in heat dissipation. By turning on the cooling fan 6, the cooling fan 6 generates wind to discharge the heat of the first heat sink 4 and the second heat sink 9 through the ventilation holes 7, further dissipating heat and improving the heat dissipation efficiency. Moreover, since the first heat sink 4, the second heat sink 9 and the support frame 2 enclose the adapter body 11 in a sealed space, the problem of the adapter body 11 coming into contact with water mist and dust is avoided, ensuring the safety of the device. In addition, by using the fixing block 3 to suspend the power adapter, it is beneficial to the heat dissipation of the power adapter. Additionally, by opening the outer shell 1, the two support frames 2 move away from each other along with the outer shell 1, and then invert the bottom outer shell 1. Under the action of gravity, the second heat sink 9 is removed from the groove 8, facilitating its repair or replacement, extending the service life of the device. At the same time, the first heat sink 4 is used to dissipate the heat generated by the motor of the operating cooling fan 6, avoiding the situation where the motor of the cooling fan 6 is at a high temperature for a long time and extending the service life of the cooling fan 6.

Therefore, in any regard, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to encompass all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
