[0041] The high-power chargers on the market currently have problems such as high cost, rapid heating, and low heat dissipation efficiency. When a high-power charger charges an electronic device, the charging power may be reduced due to the large amount of heat generated by the charger itself, which slows down the charging speed and thus affects the user's experience.

[0042] In order to improve heat dissipation, a large amount of heat dissipation material is arranged inside the charger, which increases the volume and weight of the charger, which may cause inconvenience to the user when carrying the charger. In addition, in a humid environment (such as the back-to-south season, plum rain season, etc.), the internal components of the charger are prone to damage.

[0043] Therefore, the present application proposes a charging device heat dissipation control system, which dynamically adjusts the rotating speed of the heat dissipation fan by monitoring the environmental parameters and the operating parameters of the charging interface, thereby reducing the temperature and humidity inside the charging device. The charging device heat dissipation control system can actively dissipate heat from the charging device, reducing the manufacturing cost of the charging device, and reducing the volume and weight of the charging device.

[0044] Embodiments

[0045] Reference Figures 1-5 In the present embodiment, a charging device heat dissipation control system is proposed, which is applied to a charging device 10. The charging device heat dissipation control system comprises:

[0046] A heat dissipation fan 100 is arranged inside the charging device 10;

[0047] An operating parameter detection module 200 is configured to detect the operating parameters of the charging interface 500 of the charging device 10.

[0048] an environmental detection module 300 for detecting an environmental parameter;

[0049] a controller 400 for controlling the rotating speed of the cooling fan 100 according to the operating parameter and the environmental parameter.

[0050] The cooling fan 100, the operating parameter detection module 200 and the environmental detection module 300 are electrically connected to the controller 400.

[0051] When the charging device 10 is charging the electronic device, the operating parameter detection module 200 detects the operating parameter of the charging interface 500 in real time, and the environmental detection module 300 detects the environmental parameter in real time. The controller 400 controls the rotating speed of the cooling fan 100 according to the operating parameter and the environmental parameter, thereby actively cooling the charging device 10 and improving the cooling efficiency and effect.

[0052] In this embodiment, the charging device 10 is actively cooled by the cooling fan 100, so that a large amount of cooling materials does not need to be arranged inside the charging device 10 (only a small amount of cooling materials is needed), thereby reducing the manufacturing cost of the charging device 10 and reducing the volume and weight of the charging device 10.

[0053] The controller 400 can be a microprocessor or a single-chip microcomputer.

[0054] The cooling fan 100 can be a micro high-speed fan, which has the advantages of small volume, light weight and high rotating speed. The specific structure of the cooling fan 100 can refer to the existing notebook internal fan. The cooling fan 100 can be of the type of Delta AFB02505HA, Delta KSB05105HB-9M2L, etc.

[0055] In this embodiment, the operating parameter detection module 200 includes a temperature sensor 210 or / and an electric parameter detection module 220. The sensitive element of the temperature sensor 210 is attached to the charging interface 500, and the electric parameter detection module 220 is electrically connected to the charging interface 500.

[0056] Further, the electric parameter detection module 220 includes a current sensor 221 and a voltage sensor 222. When the charging interface 500 is charging the electronic device, the current sensor 221 detects the charging current of the charging interface 500 in real time, and the voltage sensor 222 detects the charging voltage of the charging interface 500 in real time. The charging power of the charging interface 500 can be obtained by the product of the charging current and the charging voltage.

[0057] When the number of charging interfaces 500 is multiple, the electric parameter detection module 220 corresponds to the charging interface 500 one by one, that is, each charging interface 500 is connected with one electric parameter detection module 220, so that the charging power of each charging interface 500 can be monitored. In some embodiments, when the total charging power of all charging interfaces 500 exceeds a certain value at the same time, the controller 400 controls the cooling fan 100 to reach the corresponding speed.

[0058] In the embodiment, the environment detection module 300 includes a humidity sensor 310. The humidity sensor 310 is fixedly arranged in the inside of the charging device 10.

[0059] As shown in Figure 6 , the charging device 10 is provided with a dehumidifying piece 600, which is used for drying the air in the inside of the charging device 10. Specifically, the dehumidifying piece 600 can absorb the water vapor in the inside of the charging device 10, so that the inside of the charging device 10 can be kept relatively dry.

[0060] As shown in Figure 7 , the dehumidifying piece 600 includes a connecting cover 610 and a hollow placement cover 620. The connecting cover 610 and the placement cover 620 can be fixedly connected through clamping, screw connection or the like.

[0061] The inside of the placement cover 620 is used for storing a drying agent, wherein the drying agent can be wrapped in a breathable packaging bag. The placement cover 620 is provided with a ventilation hole, so that air can flow into the inside of the placement cover 620.

[0062] As shown in Figure 8 , the charging device 10 is provided with a through hole 11 and a receiving hole 12. The through hole 11 is used for allowing the placement cover 620 to pass through, and the receiving hole 12 is used for accommodating the connecting cover 610.

[0063] The through hole 11 and the receiving hole 12 are coaxially arranged, and the aperture of the through hole 11 is smaller than the aperture of the receiving hole 12. The receiving hole 12, the through hole 11 and the inner cavity of the charging device 10 are sequentially connected and communicated.

[0064] The installation steps of the dehumidifying piece 600 are as follows:

[0065] The packaging bag with the drying agent is placed in the placement cover 620 through the opening at the top of the placement cover 620;

[0066] The connecting cover 610 is covered on the opening at the top of the placement cover 620, and the connecting cover 610 and the placement cover 620 are connected;

[0067] The placement cover 620 is inserted into the inner cavity of the charging device 10 through the through hole 11, and the connecting cover 610 is inserted into the receiving hole 12.

[0068] An elastic sealing ring may be provided on the outer periphery of the connecting cover 610, wherein the sealing ring abuts against the inner wall of the accommodating hole 12, thereby achieving sealing of the accommodating hole 12; at the same time, the connecting pipe is fixed through the interference fit between the sealing ring and the accommodating hole 12.

[0069] like Figure 9 and Figure 10 As shown, the charging device 10 includes a first housing wall 13 and a second housing wall 14. An air inlet 15 is defined on the first housing wall 13, and an air outlet 16 is defined on the second housing wall 14. Both the air inlet 15 and the air outlet 16 include a plurality of through holes arranged in an array. The first and second housing walls 13, 14 are arranged parallel to and opposite each other.

[0070] The air inlet portion 15 and the air outlet portion 16 may be covered with a filter structure such as a filter membrane or a filter mesh, thereby filtering particulate matter such as dust.

[0071] The heat dissipation fan 100 is closer to the second casing wall 14 than to the first casing wall 13 , wherein the air outlet side of the heat dissipation fan 100 faces the exhaust portion 16 .

[0072] After the cooling fan 100 is started, the air inside the charging device 10 will be discharged to the outside of the charging device 10 through the exhaust part 16, and negative pressure will be generated inside the charging device 10; due to the effect of negative pressure, the external air will be sucked into the interior of the charging device 10 through the air inlet part 15, thereby realizing air circulation and achieving the purpose of heat dissipation, preventing the charging device 10 from overheating.

[0073] The number of the charging interfaces 500 is one or more. When the number of the charging interfaces 500 is multiple, the number of the charging interfaces 500 can be two, three, four, five, etc.

[0074] In this embodiment, there are multiple charging ports 500 .

[0075] The charging interface 500 includes a USB 2.0 interface, a USB 3.0 interface, and / or a Type-C interface. The type of the charging interface 500 can be configured as needed. For example, in some embodiments, there are two charging interfaces 500, one USB 2.0 interface and the other Type-C interface; in some embodiments, there are three charging interfaces 500, each including a USB 2.0 interface, a USB 3.0 interface, and a Type-C interface; and in some embodiments, there are four charging interfaces 500, including two USB 3.0 interfaces and two Type-C interfaces.

[0076] In the embodiment, when the charging device 10 is in operation, the following method can be used to control the rotating speed of the cooling fan 100:

[0077] When the first trigger condition is reached, the controller 400 controls the rotating speed of the cooling fan 100 to reach n1, and n1 is 5-20 r / min; wherein the first trigger condition includes: the sum of the charging power of all charging interfaces 500 reaches P1, 0

[0078] When the second trigger condition is reached, the controller 400 controls the rotating speed of the cooling fan 100 to reach n2, and n2 is 25-40 r / min; wherein the second trigger condition includes: the sum of the charging power of all charging interfaces 500 reaches P2, 50W

[0079] When the third trigger condition is reached, the controller 400 controls the rotating speed of the cooling fan 100 to reach n3, and n3 is 50-60 r / min; wherein the third trigger condition includes: the sum of the charging power of all charging interfaces 500 reaches P3, 100W

[0080] When the fourth trigger condition is reached, the controller 400 controls the rotating speed of the cooling fan 100 to reach n4, and n4 is 70-90 r / min; wherein the fourth trigger condition includes: the sum of the charging power of all charging interfaces 500 reaches P4, 150W

[0081] The charging device cooling control system proposed in the embodiment realizes dynamic adjustment of the rotating speed of the cooling fan 100 by monitoring the operating parameters of the charging interfaces 500 and the environmental parameters, thereby reducing the temperature and humidity inside the charging device 10.

[0082] In the embodiment, a charging device 10 is also proposed, which includes the charging interfaces 500 and the charging device cooling control system mentioned above.

[0083] During use of the charging device 10, the controller 400 can intelligently control the rotating speed of the cooling fan 100 according to the total output power and other parameters of all charging interfaces 500, so as to realize intelligent cooling of the charging device 10.

[0084] In addition, by using the active heat dissipation mode, the use amount of the heat dissipation material can be effectively reduced, thereby reducing the use cost of the heat dissipation material. In the case of the same rated output power, compared with the existing charger, the volume and weight of the charging device 10 can be reduced by 20-30%.
