[0043] The heat dissipation structure and the charging device according to the embodiments of the utility model are described below with reference to the drawings.

[0044] The utility model aims at providing an embodiment of a heat dissipation structure, which can be part of a charging device.

[0045] Therefore, with reference to Figure 1 and Figure 2 , the utility model also aims at providing an embodiment of a charging device, which has a heat dissipation structure.

[0046] In this embodiment, the charging device is a charger with wireless charging function, but it can also be other forms of charger.

[0047] Compared with the prior art, the heat dissipation structure of the utility model can reduce the noise generated by heat dissipation and improve the use experience. At the same time, the charging device of the utility model can reduce the noise during charging by applying the above-mentioned heat dissipation structure, so that the charging device can be placed near the user, which is convenient for the user to use.

[0048] With reference to Figures 1 to 6 , the charging device of the utility model comprises a front cover module 250 and a rear cover module 140, and the front cover module 250 and the rear cover module 140 form an installation cavity, and the installation cavity is installed with a wireless charging assembly, a mainboard for controlling the charging process and a heat dissipation part.

[0049] At the same time, at the junction of the front cover module 250 and the rear cover module 140, the embodiment further provides a key, an electrical interface and the like, which is convenient for connecting external power supply and performing charging control operation.

[0050] For the heat dissipation structure, the heat dissipation structure mainly comprises a heat dissipation seat 100 and a back cover module 140.

[0051] The heat dissipation seat 100 comprises a substrate 110, one side of the substrate 110 is a heated area, and the other side of the substrate 110 is a heat dissipation area, the heat dissipation area is provided with a plurality of heat dissipation fins 120, and the space between two heat dissipation fins 120 is used to form a heat dissipation air duct 130.

[0052] For the space between two heat dissipation fins 120 used to form the heat dissipation air duct 130, it can be that the heat dissipation air duct 130 is formed between two adjacent heat dissipation fins 120, or the heat dissipation air duct 130 is formed between two non-adjacent heat dissipation fins 120, and the heat dissipation fin 120 between the two heat dissipation fins 120 is lower.

[0053] In some specific embodiments of the utility model, the substrate 110 can be provided with a length direction, the heated area comprises a mainboard heated subarea 330 and a charging heated subarea 340 arranged along the length direction of the substrate 110, so that the charging part can be cooled, and the mainboard for controlling the charging can also be cooled, so that the charging device is fully cooled.

[0054] In some specific embodiments of the utility model, the heat dissipation fin 120 can be arranged along the length direction of the substrate 110, the length of the heat dissipation fin 120 is increased, the strength of the heat dissipation fin 120 is increased, the heat dissipation fin 120 is not easy to fall down, and meanwhile, the number of the heat dissipation air duct 130 can be reduced, so that the charging device can be provided with a smaller air outlet 350, and the arrangement difficulty is reduced.

[0055] In some specific embodiments of the utility model, the substrate 110 can also be circular, and the heated area of the substrate 110 only cools the charging part, which is beneficial to reduce the occupied space of the heat dissipation seat 100, and also facilitates the design of the charging device to be smaller in appearance and reduce the occupied space.

[0056] In some specific embodiments of the utility model, the heat dissipation structure can comprise a heat dissipation fan 230, the heat dissipation fan 230 generates airflow, the airflow flows through the heat dissipation air duct 130, so that the heat exchange with the heat dissipation fin 120 is strengthened, and the heat dissipation effect is improved.

[0057] In some specific embodiments of the utility model, the heat dissipation fan 230 can be installed on the substrate 110, and the heat dissipation fin 120 is provided with a avoiding concave position 240 for accommodating the heat dissipation fan 230.

[0058] It is easy to understand that, by arranging the heat dissipation fan 230 on the substrate 110, the material characteristics of the substrate 110 can be utilized to firmly and stably install the heat dissipation fan 230, so that the heat dissipation fan 230 can reliably operate.

[0059] And the heat dissipation fin 120 is provided with the avoiding concave position 240, which can reduce the size of the charging device in the thickness direction of the substrate 110, reduce the occupied space of the charging device, facilitate placement or arrangement. Placement refers to placing the charging device on the desktop or countertop, while arrangement refers to embedding the charging device in various devices such as computer desks, sofas, and cars.

[0060] At the same time, since the heat dissipation fan 230 is arranged in the middle of the heat dissipation fin 120, the heat dissipation air duct 130 can form two sections of air outlet air ducts, the airflow of the two sections of air outlet air ducts flows in opposite directions and is separated from each other, which can shorten the airflow length and reduce the flow resistance.

[0061] Moreover, the area sum of the air outlet 350 can be increased, the airflow volume can be increased, and the heat dissipation efficiency can be improved.

[0062] Referring to Figure 3 In some specific embodiments of the present application, the heat dissipation seat 100 can be installed on the front cover module 250, so that the heated area of the heat dissipation seat 100 is close to or in contact with the mainboard, and the heated area of the heat dissipation seat 100 is in contact with the heat-conducting silicone grease of the charging part, so as to ensure that the heat dissipation seat 100 is continuously and reliably heated, thereby reducing the temperature of the heating part and avoiding overheating of the charging device and failure.

[0063] At the same time, the heat dissipation seat 100 is installed on the front cover module 250, which is also conducive to simplifying the power supply connection of the heat dissipation fan 230.

[0064] If the heat dissipation seat 100 and the heat dissipation fan 230 are installed on the rear cover module 140, the front cover module 250 and the rear cover module 140 both have electrical components, so one of the front cover module 250 and the rear cover module 140 needs to be provided with a longer wire to connect the other one to meet the electrical needs, which makes the installation of the charging device more complicated, and at the same time, the arrangement of the wire needs to be considered. For example, during assembly, part of the wire is not constrained, and the wire is prone to be located at the connection between the front cover module 250 and the rear cover module 140, and the wire is prone to be damaged due to extrusion.

[0065] Due to design and modeling needs, the rear cover module 140 is not flat, but is more likely to arch backward, while the heat dissipation fin 120 is more likely to be flush, so that a gap is formed between the rear cover module 140 and the heat dissipation fin 120. When the heat dissipation fan 230 generates airflow, part of the airflow will flow to the gap instead of being discharged from the air outlet 350, that is, the airflow backflow phenomenon occurs. The airflow backflow will impact the inner surface of the rear cover module 140, which is not conducive to the discharge of the airflow and will also produce noise, affecting the user experience. Especially, the charging device is often used for charging mobile phones, and the position of the charging device is close to the user. Even if the volume or decibel is very low, it will still affect the user.

[0066] Referring to Figure 4 and Figure 5 In the embodiment, for the back cover module 140, the back cover module 140 has a containing cavity 150 for accommodating a plurality of heat dissipation fins 120, a cavity bottom of the containing cavity 150 is provided with an air inlet, and a side wall of the containing cavity 150 is provided with an air outlet 350, and the air inlet and the air outlet 350 are communicated with the heat dissipation air duct.

[0067] The cavity bottom of the containing cavity 150 is provided with a gland 160 for abutting against a side of the heat dissipation fin 120 away from the base plate 110, and the gland 160 is used to cooperate to form the heat dissipation air duct 130.

[0068] In summary, the back cover module 140 is provided, so that the back cover module 140 has the containing cavity 150, so that the heat dissipation fin 120 can be hidden inside the product such as the charging device, the external touch is reduced, and the damage risk of the heat dissipation fin 120 is reduced.

[0069] Therefore, the thickness of the heat dissipation fin 120 can be set to be smaller, and then the number of the heat dissipation fin 120 is increased, the heat dissipation area is increased, and the heat dissipation capacity is improved without increasing the occupied space.

[0070] The gland 160 is provided, the gland 160 can cooperate to form the heat dissipation air duct 130, so that the heat dissipation airflow flows in one direction and in order, the heat dissipation airflow is prevented from flowing back from the gap between the cavity bottom of the containing cavity 150 and the heat dissipation fin 120, and the heat dissipation noise is reduced.

[0071] At the same time, since the gland 160 is provided, the shape limitation of the cavity bottom of the containing cavity 150 is also reduced, so that the external shape of the back cover module 140 can meet the modeling needs, and meanwhile, the entity thickness of the back cover module 140 is avoided to be increased, the material is reduced, and the production defects such as shrinkage caused by excessive wall thickness are also reduced.

[0072] In the embodiment, the bottom wall of the back cover module 140, that is, the cavity bottom of the containing cavity 150 is provided with the air inlet, and the side wall of the back cover module 140, that is, the side wall of the containing cavity 150 is provided with two air outlets 350, and the two air outlets 350 are located at two ends in the length direction of the base plate 110, so that the heat dissipation fins 120 on both sides of the heat dissipation fan form two airflows in opposite directions, the path length of each airflow is shortened, the airflow resistance is reduced, and the air exchange is accelerated.

[0073] In some specific embodiments of the utility model, the front cover module 250 can also have a structure for forming the air inlet or the air outlet 350, but the influence on the charging device needs to be considered, such as the influence of dust in the air inlet airflow on the charging part or the mainboard, and such as the influence of the edge of the front cover module 250 being hollowed out on the strength of the front cover module 250.

[0074] In some specific embodiments of the utility model, the cavity bottom of accommodating cavity 150 can be provided with mounting groove 170, mounting groove 170 is used to install gland 160, the side wall of mounting groove 170 is matched with the outer contour of gland 160, and the bottom wall of mounting groove 170 is provided with a plurality of support ribs 180 for supporting gland 160.

[0075] It is easy to understand that the embodiment can limit the edge of gland 160 by setting mounting groove 170, avoid the deviation of gland 160, and the entity forming mounting groove 170 and support rib 180 can also enhance the strength of rear cover module 140, and avoid the local wall thickness too large during injection molding production.

[0076] In some specific embodiments of the utility model, the entity forming mounting groove 170 can have an opening to fully utilize the internal space of mounting groove 170, meet the needs of installing first cover body 270, and avoid increasing the specifications of the charging device.

[0081] In some specific embodiments of the utility model, the cavity bottom of accommodating cavity 150 can be provided with a plurality of mounting columns 190, and gland 160 is provided with mounting hole 200 for accommodating mounting column 190 to penetrate, so as to be installed.

[0085] It is easy to understand that, by providing the first plate 210, on the one hand, the closed area of the grommet 160 can be reduced, and the setting difficulty of the grommet 160 can be reduced, and on the other hand, the first plate 210 can be conveniently arranged with other components, such as light emitting and sound emitting, to realize various functions.

[0086] In some specific embodiments of the present application, the number of grommets 160 can be two, and the first plate 210 is located between the two grommets 160, and one side of the grommet 160 matches the outer contour of the first plate 210.

[0087] It is easy to understand that, by providing two grommets 160, the cooperation requirement at two places can be met.

[0088] And the one side of the grommet 160 matches the outer contour of the first plate 210, which is also conducive to reducing the gap between the grommet 160 and the first plate 210, and further preventing air backflow.

[0089] In some specific embodiments of the present application, the part of the entity forming the mounting groove 170 can be a rib position, which is located between the grommet 160 and the first cover body 270, which meets the needs of preventing air backflow and positioning the grommet 160 and the first cover body 270, and simplifies the installation.
