[0043] Please refer to Figures 1-2The utility model provides a kind of wireless charger 100, including shell 1, and the semiconductor heat dissipation module 2 and wireless charging module 3 being set in shell 1;Mounting bracket 4 is set on the side wall of shell 1 corresponding semiconductor heat dissipation module 2;Extensible data line 5 is further provided in shell 1, accommodating groove 13 for accommodating data line 5 is provided in shell 1, data line 5 is spaced apart from semiconductor heat dissipation module 2, and data line 5 is electrically connected with wireless charging module 3.

[0044] Understandably, wireless charger 100 generates a large amount of heat when operating at high power, and a separate heat dissipation area needs to be provided in the shell 1. As the demand for reducing the size of the wireless charger 100 increases, the internal space becomes more limited. Most wireless chargers 100 on the market use an external power cord. The wireless charger 100 provided by the utility model integrates the external data line 5 of the wireless charger 100 in the shell 1. The integrated wireless charger 100 does not need to carry an additional data line 5, which is convenient for users to carry and use, especially suitable for use when traveling or going out, and reduces the wear and tear of the data line 5 due to bending and pulling, prolongs the service life of the data line 5, and reduces the risk of damage to the data line 5.

[0045] Further, the data line 5 is spaced apart from the semiconductor heat dissipation module 2, which provides more space for the semiconductor heat dissipation module 2, facilitates the design of a more efficient heat dissipation structure, avoids overheating of the data line 5 due to proximity to the heat source, thereby improving the heat dissipation efficiency of the semiconductor heat dissipation module 2, reducing electromagnetic interference between the data line 5 and the semiconductor heat dissipation module 2, and ensuring the stability of the wireless charger 100 when operating at high power.

[0046] It should be noted that the semiconductor heat dissipation module 2 has good electrical insulation performance. Semiconductor devices are usually small in size and high in integration, which can effectively avoid affecting the electrical performance of electronic components and reduce the size of the semiconductor heat dissipation module 2, achieving miniaturization and integration.

[0047] Further, Figure 3 The shell 1 includes an upper shell 11 disposed away from the bracket side, and the upper shell 11 is provided with a heat dissipation groove 111 corresponding to the semiconductor heat dissipation module 2. The semiconductor heat dissipation module 2 includes a refrigeration fin 21, and the refrigeration fin 21 is at least partially disposed in the heat dissipation groove 111.

[0048] Specifically, the refrigeration fin 21 is a device that uses the Peltier effect of semiconductor materials to achieve refrigeration. It can transfer heat from one end to the other end when powered on, thereby achieving a refrigeration effect. By providing a refrigeration fin 21 inside the wireless charger 100, the heat generated by the wireless charger 100 when operating at high power is reduced, ensuring the stability and safety of the device.

[0049] The refrigeration sheet 21 can be installed near the position where the electrical element generates heat, directly cooling the electrical element to improve charging efficiency. The refrigeration sheet 21, as an independent refrigeration component, can cooperate with the heat dissipation sheet, the cold conducting block and other structures to form a complete heat dissipation system. On the basis of the heat dissipation sheet, the heat dissipation fan 22 can be added to significantly improve the heat dissipation efficiency. The heat dissipation fan 22 accelerates the heat dissipation by forced air flow, and is suitable for high-power wireless chargers 100.

[0050] Further, the heat dissipation groove 111 provides a special heat dissipation area for the refrigeration sheet 21, which is a hollow groove inside the upper shell 11 and provides physical support for the refrigeration sheet 21. The structure of the heat dissipation groove 111 is optimized to help the refrigeration sheet 21 increase the contact area with the heat dissipation components, effectively dissipate the heat generated by the refrigeration sheet 21, achieve more uniform heat distribution, and thus improve the overall heat dissipation efficiency.

[0051] As can be understood, the heat dissipation groove 111 is a support structure for the refrigeration sheet 21 inside the shell 1, and the shell 1 is a heat conduction medium between the heat dissipation groove 111 and the external environment. By reasonably designing the shape and position of the heat dissipation groove 111, more uniform heat distribution inside the shell 1 can be achieved, and then the heat is transferred to the external environment through the shell 1.

[0052] Further, please refer to Figure 3 and Figure 5 The semiconductor heat dissipation module 2 further comprises a heat dissipation fan 22 corresponding to the refrigeration sheet 21, and the shell 1 is provided with a heat conducting grid 14 corresponding to the heat dissipation fan 22, and the heat dissipation fan 22 is fixedly connected with the heat conducting grid 14.

[0053] As can be understood, the heat dissipation fan 22 can significantly improve the heat dissipation efficiency on the basis of the refrigeration sheet 21. The heat dissipation fan 22 accelerates the heat dissipation by forced air flow, and is suitable for high-power wireless chargers 100. The heat conducting grid 14 provides physical support for the heat dissipation fan 22 and other heat dissipation components, and can also optimize the heat conduction path to reduce the loss of heat in the transmission process and improve the heat dissipation efficiency.

[0054] Specifically, the heat dissipation fan 22 can quickly conduct the heat absorbed by the heat conducting grid 14 to the external environment through air convection, dissipating the heat into the air to improve the heat dissipation efficiency. The heat conducting grid 14 is made of a composite material with high thermal conductivity and flexibility, which provides physical support for the heat dissipation fan 22 and is also used for heat conduction between the wireless charging module 3 and the refrigeration sheet 21 to ensure uniform heat distribution.

[0055] As a non-limiting embodiment, the wireless charger 100 provided by the utility model can additionally add a heat-distributing sheet on the heat-conducting grid 14 to uniformly distribute heat and reduce local overheating. After the heat-distributing sheet uniformly distributes heat, the heat is forcibly dissipated by the heat-dissipating fan 22, thereby improving the overall heat-dissipating efficiency.

[0056] Further, the wireless charging module 3 is arranged in the upper shell 11 and corresponds to the semiconductor heat-dissipating module 2. The cold end 211 of the refrigeration sheet 21 corresponds to the heat-dissipating groove 111 and is attached to the wireless charging module 3. The hot end 212 of the refrigeration sheet 21 is attached to the heat-conducting grid 14 away from the heat-dissipating fan 22.

[0057] Understandably, the wireless charging module 3 generates a large amount of heat during the charging process. The cold end 211 of the refrigeration sheet 21 directly attaches to the wireless charging module 3 through the heat-dissipating groove 111, which can quickly absorb the heat generated by the wireless charging module 3 during high-power operation and reduce the temperature of the wireless charging module 3.

[0058] Specifically, the working principle of the refrigeration sheet 21 is based on the Peltier effect. When a direct current passes through an electric couple composed of two different semiconductor materials in series, the cold end 211 absorbs heat, and the other hot end 212 releases heat. This thermoelectric effect enables the refrigeration sheet 21 to transfer the heat of the wireless charging module 3 to the side of the heat-dissipating fan 22 when powered on, effectively reducing the heat inside the wireless charger 100.

[0059] Further, the heat-conducting grid 14 further includes a bottom plate 141 and heat-dissipating fins 142 arranged on the bottom plate 141 and facing the heat-dissipating fan 22. The shell 1 has an air inlet 15 on the side facing the heat-dissipating fan 22. The side of the shell 1 adjacent to the air inlet 15 is provided with an air outlet 16. The side of the heat-dissipating fins 142 faces the air outlet 16.

[0060] Understandably, the heat-conducting grid 14 uniformly transfers heat to the heat-dissipating fins 142. The cooperation of the heat-conducting grid 14 and the heat-dissipating fins 142 can reduce the contact thermal resistance between the heat source and the heat-dissipating component, ensuring that the heat can be quickly conducted to the heat-dissipating fins 142. The larger the surface area of the heat-dissipating fins 142, the better the heat-dissipating effect.

[0061] It should be noted that the air inlet 15 and the air outlet 16 form a complete air flow path, the front air inlet 15 can introduce cold air, and the side air outlet 16 can exhaust hot air, that is, the air inlet 15 is arranged on the side of the shell 1 facing the heat dissipation fan 22, and the air outlet 16 is arranged on the side of the heat dissipation fin 142, forming a complete air flow path, air enters from the air inlet 15, smoothly passes through the heat dissipation fin 142, and is exhausted from the air outlet 16, thereby taking away heat and avoiding heat accumulation, and further improving the heat dissipation effect; the hot air is quickly exhausted, and the cold air is continuously supplemented, ensuring that the air flows fully between the heat dissipation fins 142 and improving the heat dissipation efficiency.

[0062] Specifically, the heat dissipation fin 142 can also serve as a wind guide support plate, and the arrangement direction of the heat dissipation fin 142 is parallel to the rear air inlet direction of the heat dissipation fan 22, which not only has no resistance to the rear air inlet of the heat dissipation fan 22, but also has a guiding effect, thereby improving the overall air performance of the heat dissipation fan 22.

[0063] As a non-limiting embodiment, by optimizing the shape, spacing and height of the heat dissipation fin 142 and the cooperation with the heat dissipation fan 22, the heat dissipation efficiency can be significantly improved. For example, the needle-shaped fin design has the advantages of being light and small in size, and also has high volume efficiency, which is suitable for forced convection heat dissipation and uniformly dissipates heat into the air; by increasing the number or length of the heat dissipation fin 142, the heat dissipation area can be effectively increased, thereby improving the heat dissipation efficiency.

[0064] Further, the heat dissipation fin 142 is arranged in a fan shape on the outer edge of the bottom plate 141 close to the heat dissipation fan 22, guides the air flow to be uniformly distributed, reduces air flow bypassing, increases the heat dissipation area, and makes the air flow more easily pass through the heat dissipation fin 142, and cooperates with the rotation characteristics of the fan, so that the air flow provided by the fan can be better utilized.

[0065] Further, please refer to Figure 3 and Figure 4 The wireless charger 100 comprises a rotating assembly 6, and the data line 5 is wound and stored in the accommodating groove 13 through the rotating assembly 6; an opening 123 is formed in the side of the shell 1 away from the air outlet 16, and the data line 5 extends out of the shell 1 through the opening 123, and a wire buckle 52 is arranged on the data line 5 corresponding to the opening 123.

[0066] Understandably, the rotating assembly 6 allows the data line 5 to be wound and stored in the accommodating groove 13 when not in use, and through the winding function of the rotating assembly 6, the data line 5 can be neatly stored in the accommodating groove 13, reducing frequent bending and pulling, and prolonging the service life of the data line 5.

[0067] Furthermore, the data cable 5 is telescopic, and the user needs to adjust the length of the data cable 5 according to actual needs. The data cable 5 extends or retracts from the opening of the housing 1. The cable buckle 52 is set on the data cable 5 and has a locking function. The cable buckle 52 is set according to the shape and size of the opening 123 on the housing 1 and plays a role in fixing the data cable 5 that extends out of the opening 123. The data cable 5 remains stable during use and avoids inconvenience caused by retraction.

[0068] like Figure 2 The receiving slot 13 shown is located at the rear of the wireless charging module 3, that is, the data cable 5 is stored at the rear of the wireless charging module 3 to prevent the charging heat from affecting the data cable 5.

[0069] Specifically, users can adjust and fix the required cable length by moving the cable clip 52 on the data cable 5 to meet the needs of different scenarios. When not in use, the cable clip 52 can be stored in the opening 123, making the connection between the data cable 5 and the housing 1 neater.

[0070] Specifically, the cable clip 52 can slide along the data cable 5. The size of the cable clip 52 matches the diameter of the data cable 5. At the same time, the size of the cable clip 52 is greater than or equal to the opening 123 to achieve the function of locking the data cable.

[0071] Further, please refer to Figure 3 The housing 1 also includes a lower housing 12 disposed opposite to the upper housing 11, a receiving groove 13 disposed inside the lower housing 12, and a storage groove 122 disposed on the outer side of the lower housing 12. The data cable 5 includes a plug 51, which is magnetically fixed to the storage groove 122.

[0072] Understandably, the magnetic fixation ensures that the plug 51 of the data cable 5 is stably fixed in the storage slot 122, thereby limiting the wireless charger 100 to be fixedly stored in the storage slot 122 of the lower housing 12 when it is not in use, so that it will not be messy on the outside, improving the aesthetics of the wireless charger 100 and making it easier to store and organize.

[0073] Specifically, the outer side of the lower housing 12 is also provided with an annular groove to accommodate the data cable 5, so that the data cable 5 is completely housed inside the outer wall of the lower housing 12, and the opening 123 for the data cable 5 to extend out of the housing 1 is also provided on the lower housing 12.

[0074] Furthermore, the upper housing 11 and the lower housing 12 are detachably connected, making it easier to access the heat dissipation fins 142, heat dissipation fan 22, etc. in the semiconductor heat dissipation module 2, facilitating cleaning and replacement, thereby ensuring the efficient operation of the semiconductor heat dissipation module 2.

[0075] Further, please refer to Figure 3 - Figure 5The heat-conducting grid 14 further comprises a baffle plate 143 arranged on the side facing the accommodating groove 13, and the baffle plate 143 and the heat-dissipating fins 142 together form a heat-dissipating chamber 144.

[0076] It can be understood that the baffle plate 143 is arranged on the side facing the accommodating groove 13, so as to avoid the wind of the heat-dissipating fan 22 directly blowing to the data line 5 in the accommodating groove 13, avoid the data line 5 being damaged due to long-time exposure to the airflow, prolong the service life of the data line 5, and through the baffle plate 143 arranged in the cavity, the cavity can be divided and a good air duct can be formed, the air flow path is optimized, the heat-dissipating efficiency is improved, the heat-dissipating chamber 144 uniformly distributes the heat, the local overheating phenomenon is avoided, and the overall heat distribution is optimized.

[0077] Specifically, the heat-dissipating fins 142 are arranged around the heat-dissipating chamber 144, so as to ensure that the air can fully flow through the heat-dissipating fins 142 and take away the heat on the heat-dissipating fins 142.
