Description

[0002] In recent years, with the rapid development of wireless charging technology, wireless charging devices have received extensive attention due to their convenience and flexibility. However, wireless charging technology still faces some technical challenges in practical applications, and the most prominent one is the loss problem during the energy transmission process. During wireless charging, due to the action of the electromagnetic field, energy will inevitably be lost when transmitted between the transmitting end and the receiving end. This loss leads to the generation of a large amount of heat. If this heat cannot be dissipated in a timely and effective manner, it will cause the product temperature to rise, thereby affecting the safety and stability of the product. Specifically, high temperature will cause the charging power of the product to decrease and affect the user experience.
[0003] To address this problem, some products adopt a metal shell design to enhance the heat dissipation effect. Although the metal shell has good thermal conductivity, heat may accumulate in local areas, forming a high-temperature area, causing the product to feel hot during use and even posing a risk of scalding users, thus affecting the user experience. Summary of the Utility Model

[0032] Please refer to Figures 1 to 4 , an embodiment of the present utility model discloses a charging device with a heat dissipation function, which includes: a plastic housing 1 and a charging assembly 2. The charging assembly 2 is located inside the plastic housing 1, and a heat dissipation assembly 3 is provided between the charging assembly 2 and the plastic housing 1. The heat dissipation assembly 3 is used to absorb the heat of the charging assembly 2 and dissipate it.
[0033] In this embodiment, the heat dissipation component 3 is in close contact with or near the charging component 2. The heat dissipation component 3 can effectively absorb the heat generated by the charging component 2 and then dissipate it to the external environment. By dissipating heat in a timely manner, the charging component 2 can be maintained at a relatively low operating temperature, avoiding the problem in the prior art where the charging power has to be reduced due to the overheating of the charging device, resulting in a slow charging speed. At the same time, since the heat dissipation component 3 effectively reduces the temperature of the charging device, the potential safety hazards caused by overheating are reduced. It should be noted that in this embodiment, the housing of the charging device is a plastic housing 1. The heat dissipation component 3 absorbs and dissipates the heat of the charging component 2, while the plastic housing 1 ensures that the temperature when touched by the user will not be too high due to its plastic material, avoiding the risk of scalding the user.
[0034] Furthermore, the heat dissipation component 3 includes a metal housing 31. The metal housing 31 semi - surrounds or fully surrounds the outside of the charging component 2. Since the metal housing 31 is made of a metal material with excellent heat conduction performance, it can more effectively absorb and dissipate the heat generated by the charging component 2. It can quickly transfer the heat from the charging component 2 to the metal housing 31, and then further dissipate the heat from the metal housing 31 to the surrounding environment.
[0035] Specifically, the metal housing 31 has a U - shaped structure, and the charging component 2 is located in the U - shaped groove 311 of the metal housing 31. The U - shaped structure increases the contact area between the metal housing 31 and the air, enhancing the heat dissipation efficiency of the metal housing 31.
[0036] Furthermore, a cavity is provided inside the metal housing 31, and a heat - conducting fluid medium 32 is filled in the cavity. In this embodiment, the heat generated by the charging component 2 is first transferred to the outer wall of the metal housing 31 through the heat conduction performance of the metal housing 31. Then, the heat - conducting fluid medium 32 flows in the cavity of the metal housing 31, absorbs the heat transferred by the metal housing 31, transfers the heat from the high - temperature area to the low - temperature area, transfers the heat to the outside of the metal housing 31, and finally dissipates it to the surrounding environment, greatly improving the heat dissipation efficiency. It can dissipate the heat generated by the charging component 2 to the external environment faster. Moreover, the flow of the heat - conducting fluid medium 32 makes the temperature distribution inside the metal housing 31 more uniform, avoiding the phenomenon of local overheating.
[0037] Specifically, the heat - conducting fluid medium 32 is high - pressure oil. It can be understood that the pressure range of the high - pressure oil is above 20 MPa, and it has excellent heat conduction performance, which can quickly absorb and transfer heat, ensuring that the heat generated by the charging component 2 can be efficiently transferred to the heat dissipation structure. Optionally, the heat - conducting fluid medium 32 can also be refrigerant oil.
[0038] Further, the plastic housing 1 is provided with heat dissipation holes 4, and the heat dissipation component 3 exchanges heat with the outside air through the heat dissipation holes 4. It can be understood that through the heat dissipation holes 4, cold outside air can enter the interior of the charging device, contact the high-temperature metal housing 31, absorb heat and then be discharged, thereby reducing the temperature of the charging component 2. When the charging component 2 generates heat during operation, the heat is first transferred to the heat-conducting fluid medium 32 therein through the heat-conducting performance of the metal housing 31, and then the heat is carried to the side of the metal housing 31 facing the heat dissipation holes 4 through the flow of the heat-conducting fluid medium 32. Next, the metal housing 31 exchanges heat with the outside air through the heat dissipation holes 4 on the plastic housing 1. The outside air enters the interior of the charging device through the heat dissipation holes 4, contacts the metal housing 31 and absorbs heat, and then carries the heat and is discharged through the heat dissipation holes 4. It can be understood that since the temperature inside the charging device is higher than that of the outside air, the arrangement of the heat dissipation holes 4 can utilize the principle that heat flows upward to enhance air flow, thereby achieving the effect of enhancing the heat dissipation of the heat dissipation component 3.
[0039] Further, the charging component 2 includes a circuit board 21 and a transmitting coil 22 electrically connected to the circuit board 21. The circuit board 21 controls and manages the conversion and transmission of electrical energy, while the transmitting coil 22 wirelessly transmits electrical energy to a receiving device.
[0040] Further, during the charging process, the wireless charging base 11 and the area nearby will generate heat due to the conversion and transmission of electrical energy, developing into an area where heat is relatively concentrated. Therefore, how to effectively dissipate the heat from the wireless charging base 11 and the area nearby to ensure the stable operation of the device and the safety of users during use is a key technical problem to be solved in this solution. For this reason, the inventor proposes the following solution. In this solution, the heat dissipation holes 4 include first heat dissipation holes 414. A wireless charging base 11 opposite to the transmitting coil 22 is provided on one side of the plastic housing 1. The first heat dissipation holes 414 at least partially surround the periphery of the wireless charging base 11. By arranging the first heat dissipation holes 414 around the periphery of the wireless charging base 11, the heat of the wireless charging base 11 and the area nearby can be quickly carried away by the natural convection of air, reducing the temperature at the wireless charging base 11 and ensuring the smooth progress of the charging process.
[0041] Further, the charging component 2 further includes a battery 23 and a charging interface 24. Both the battery 23 and the charging interface 24 are electrically connected to the circuit board 21. The charging interface 24 is used to connect to an external power source to charge the battery 23.
[0042] It can be understood that the charging port 24 is an area where heat is more concentrated in the charging device. When the charging port 24 is connected to an external power source, heat may be generated due to current transmission. In order to dissipate this heat more effectively, the first heat dissipation hole 414 in this embodiment is at least partially arranged between the wireless charging seat 11 and the charging port 24 to ensure that the heat can be quickly discharged by the first heat dissipation hole 414.
[0043] Preferably, the first heat dissipation holes 414 are continuous strip holes.
[0044] In one embodiment, the plastic shell 1 includes an upper shell 12 and a lower shell 13, and the upper shell 12 and the lower shell 13 are spliced to enclose the charging component 2 and the heat dissipation component 3. Among them, the wireless charging seat 11 is located on the upper shell 12. Further, the heat dissipation hole 4 includes a second heat dissipation hole 424 and the first heat dissipation hole 414 as described above. The setting of the first heat dissipation hole 414 is not repeated. The second heat dissipation hole 424 is a plurality of strip holes provided on the lower shell 13. The heat of the metal shell can be heat exchanged with the outside air through the second heat dissipation hole 424, so that the heat dissipation efficiency of the metal shell is higher.
[0045] Compared with the prior art, the charging device with heat dissipation function of the utility model uses the principle of heat conduction through the heat dissipation component to effectively conduct the heat generated by the charging component to the heat dissipation component itself, and then dissipates the heat to the external environment through the heat dissipation component, thereby ensuring that the internal temperature of the device is effectively controlled. At the same time, the setting of the plastic shell prevents the user from feeling overheated when touching it, avoiding the risk of burns to the user and improving the user experience.
[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
