[0030] According to the high-efficiency heat dissipation type mobile power supply provided by the embodiment of the utility model, the first arrangement area 1300 and the second arrangement area 1400 are arranged in the shell 1000 respectively, the second arrangement area 1400 is located between the air inlet channel 1200 and the air outlet channel 1100, the airflow channel is formed in the second arrangement area 1400 and is communicated with the air inlet channel 1200 and the air outlet channel 1100, the heat dissipation module is arranged in the second arrangement area 1400, one end of the heat conduction component 500 is attached to the bottom of the wireless charging coil 300, the other end of the heat conduction component 500 is attached to the heat dissipation module, the heat conduction component 500 transmits the heat accumulated in the wireless charging coil 300 to the heat dissipation module, the heat dissipation module generates the directional convection from the air inlet channel 1200 to the air outlet channel 1100 in the airflow channel when operating, the airflow blows through the surface of the heat dissipation module located in the second arrangement area 1400, the heat transmitted to the heat dissipation module by the heat conduction component 500 can be quickly guided to the air outlet channel 1100 and dissipated, the rapid heat dissipation is realized, the electronic device can be smoothly charged in the process of using the mobile power supply for wireless charging, and the charging efficiency of the mobile power supply and the user experience are improved.
[0031] It can be understood that in the process of using the mobile power supply for wireless charging of the electronic device, the coil of the electronic device is attached to the wireless charging coil 300 of the mobile power supply, the heat is accumulated in the wireless charging coil 300, and in the mobile power supply, one end of the heat conduction component 500 is arranged between the wireless charging coil 300 and the power module 200, so that the one end of the heat conduction component 500 is attached to the wireless charging coil 300, the other end of the heat conduction component 500 extends to the surface of the heat dissipation module and is attached to the heat dissipation module, the heat accumulated in the wireless charging coil 300 can be transmitted to the heat dissipation module, then, the heat dissipation module generates the directional convection from the air inlet channel 1200 to the air outlet channel 1100 in the airflow channel when operating, the airflow blows through the surface of the heat dissipation module located in the second arrangement area 1400, the heat transmitted to the heat dissipation module by the heat conduction component 500 can be quickly guided to the air outlet channel 1100 and dissipated, the rapid heat dissipation is realized, the temperature of the electronic device is effectively prevented from rising to the threshold value of triggering the current limiting of wireless charging, the device is ensured to be charged in the normal temperature range, the charging speed of the electronic device is improved, the charging time is significantly shortened, and better charging experience is brought to the user.
[0032] Preferably, the electronic device can be a smart phone, a wireless earphone, a tablet computer, a smart watch or any other device that can support wireless charging.
[0033] It should be noted that the heat dissipation module can be controlled to operate through the setting of a start button or be started to operate synchronously in the process of using the mobile power supply for wireless charging of the electronic device.
[0034] It can be understood that the second arrangement area 1400 is located between the air inlet channel 1200 and the air outlet channel 1100, the heat dissipation module is arranged in the second arrangement area 1400, the cold airflow introduced by the air inlet channel 1200 can flow through the heat dissipation module, and the hot air is discharged from the air outlet channel 1100, forming an effective heat dissipation cycle, and the heat dissipation efficiency is significantly improved.
[0035] In some embodiments, the air inlet channel 1200 and the air outlet channel 1100 are both composed of a plurality of openings, and the number of openings arranged in the air inlet channel 1200 is greater than the number of openings arranged in the air outlet channel 1100.
[0036] It can be understood that the air inlet channel 1200 and the air outlet channel 1100 are both composed of a plurality of small openings arranged uniformly, the number of openings arranged in the air inlet channel 1200 is greater, on the one hand, more openings can allow more cold air to enter the second arrangement area 1400, ensuring that the heat dissipation member 420 is sufficiently cooled, on the other hand, since the air inlet channel 1200 is composed of a plurality of openings with small apertures arranged uniformly, the small aperture of the opening can avoid some external substances such as fine particulate matter or dust from entering the airflow channel from the opening during the use of the mobile power supply, affecting the normal operation of the heat dissipation module, greatly reducing the risk of heat dissipation efficiency decline or system failure caused by foreign matter invasion, thereby ensuring the stable operation and long service life of the mobile power supply under high intensity use; the number of openings arranged in the air outlet channel 1100 is less, on the one hand, it can prevent too much cold air from being discharged, thereby improving the heat dissipation efficiency, on the other hand, it can effectively reduce the airflow backflow and prevent the hot air discharged from flowing back to the second arrangement area 1400.
[0037] In some embodiments, the air inlet channel 1200 is formed by a hole on one side of the shell 1000, the air outlet channel 1100 is formed by a hole on the opposite side, the aperture of the air inlet channel 1200 is greater than the aperture of the air outlet channel 1100, an end cover matched with the air inlet channel 1200 is arranged outside the air inlet channel 1200, and an end cover matched with the air outlet channel 1100 is arranged outside the air outlet channel 1100.
[0038] It can be understood that, first, by setting a larger aperture opening on one side of the shell 1000 to form an air inlet channel 1200, opening the end cap set outside the air inlet channel 1200 during the process of charging the mobile power supply, more cold air can enter the second arrangement area 1400 without any obstruction, ensuring that the heat dissipation member 420 is fully cooled. In addition, when the mobile power supply is not needed to be charged, the end cap set outside the air inlet channel 1200 is moved above the air inlet channel, which can prevent some external substances such as fine particles or dust from entering the airflow channel from the air inlet channel 1200, preventing the normal operation of the heat dissipation module during the next use of the mobile power supply. The risk of heat dissipation efficiency decline or system failure caused by foreign matter invasion is greatly reduced, thereby ensuring the stable operation and long service life of the mobile power supply under high-intensity use. Second, a smaller aperture opening is set on the opposite side to form an air outlet channel 1100. During the process of charging the mobile power supply, the end cap set outside the air outlet channel 1100 is opened. Since the air outlet channel 1100 has a smaller aperture, it can prevent too much cold air from being discharged, thereby improving the heat dissipation efficiency. In addition, when the mobile power supply is not needed to be charged, the end cap set outside the air outlet channel 1100 is moved above the air outlet channel 1100, which can prevent some external substances such as fine particles or dust from entering the airflow channel from the air outlet channel 1100, preventing the normal operation of the heat dissipation module during the next use of the mobile power supply. The risk of heat dissipation efficiency decline or system failure caused by foreign matter invasion is greatly reduced, thereby ensuring the stable operation and long service life of the mobile power supply under high-intensity use.
[0039] In some embodiments, with reference to Figure 2 , the heat dissipation module includes a fan assembly 410 and a heat dissipation member 420. The fan assembly 410 is arranged at the top of the second arrangement area 1400, and the heat dissipation member 420 is arranged at the bottom of the second arrangement area 1400. The other end of the heat-conducting member 500 is attached to the heat dissipation member 420.
[0040] It can be understood that the fan assembly 410 is arranged at the top of the second arrangement area 1400 near the air inlet channel 1200. The fan assembly 410 rapidly introduces a large amount of cold air outside the air inlet channel 1200 into the second arrangement area, so that the heat transferred to the heat dissipation member 420 by the heat-conducting member 500 can be quickly directed to the air outlet channel 1100 and blown away, achieving rapid heat dissipation.
[0041] In some embodiments, with reference to Figure 1 , Figure 2The main control module 100 is arranged on the top of the first arrangement area 1300, and the main control module 100 is connected with the power module 200. The first arrangement area 1300 is arranged side by side with the second arrangement area 1400. The partition plate 1500 is arranged between the main control module 100 and the fan assembly 410.
[0042] It should be noted that the main control module 100 is also connected with the fan assembly 410 and the charging coil 300. The main control module 100 is arranged on the top of the first arrangement area 1300, and the power module 200 is arranged on the bottom of the first arrangement area 1300.
[0043] It should be noted that in the process of using the mobile power supply to wirelessly charge the electronic device, the coil of the electronic device is attached to the wireless charging coil 300 of the mobile power supply. Heat accumulates in the wireless charging coil 300. If the main control module 100 is arranged below the wireless charging coil 300, the performance and stability of the main control module 100 will be seriously affected due to the impact of high temperature. Arranging the main control module 100 on the top of the power module 200 can effectively prevent the main control module 100 from being impacted by high temperature from the wireless charging coil 300, which helps to improve the working efficiency and stability of the main control module 100, prolong its service life, and reduce the risk of system failure caused by overheating.
[0044] It should be noted that the first arrangement area 1300 is arranged side by side with the second arrangement area 1400. The main control module 100 is arranged side by side with the fan assembly 410. The power module 200 is arranged side by side with the heat dissipation member 420. The main control module 100 and the fan assembly 410 are separated by the partition plate 1500. This can ensure that the airflow introduced by the fan assembly 410 from the air inlet channel 1200 flows to the heat dissipation member 420 located at the lower part of the second arrangement area 1400, achieving rapid heat dissipation.
[0045] In some embodiments, with reference to Figure 2 , Figure 3 , Figure 4 The heat dissipation member 420 is provided with a flow guide groove 421. One end of the flow guide groove 421 faces the fan assembly 410, and the other end of the flow guide groove 421 faces the air outlet channel 1100.
[0046] Preferably, the heat dissipation member 420 can be a square body, a cone body or a column body structure, which is not limited here.
[0047] It should be noted that the design of the flow guide groove 421 below the heat dissipation piece 420 can help to reduce the resistance of the airflow, and make the airflow flow along the predetermined path in the second arrangement area 1400, guide more low-temperature airflow to fully contact the heat dissipation piece 420 to achieve rapid heat exchange, and smoothly guide the heat out of the air outlet channel 1100, so as to effectively control the temperature of the wireless charging coil 300 during the charging process, and further improve the heat dissipation efficiency and the charging efficiency.
[0048] In some embodiments, with reference to Figure 2 , Figure 3 , Figure 4 The flow guide groove 421 is provided with a plurality of heat dissipation fins 422.
[0049] Preferably, the heat dissipation fins 422 can be square, which is not limited here.
[0050] It should be noted that the plurality of heat dissipation fins 422 are evenly arranged in the flow guide groove 421, which effectively increases the heat exchange area of the heat dissipation piece 420. Specifically, the plurality of heat dissipation fins 422 further divide the large flow guide groove 421 in the heat dissipation piece 420 into a plurality of small flow guide grooves 421, so that the airflow flows towards the several flow guide grooves 421 in the heat dissipation piece 420 in the second arrangement area 1400, guiding more low-temperature airflow to fully contact the heat dissipation piece 420 to achieve rapid heat exchange, and smoothly guiding the heat out of the air outlet channel 1100, further improving the heat dissipation efficiency and the charging efficiency.
[0051] In some embodiments, with reference to Figure 2 , Figure 3 The heat dissipation piece 420 includes a first substrate 423, a second substrate 424 and a third substrate 425, the second substrate 424 and the third substrate 425 are arranged in parallel, the second substrate 424 and the third substrate 425 are both vertically connected with the first substrate 423, the flow guide groove 421 is formed between the second substrate 424 and the third substrate 425, and the other end of the heat conduction member 500 is attached to the first substrate 423.
[0052] It should be noted that with reference to Figure 2 The heat dissipation piece 420 is arranged at the bottom of the second arrangement area 1400, the first substrate 423 can be arranged in parallel with the surface of the shell 1000, the second substrate 424 and the third substrate 425 are arranged below the first substrate 423 to form the flow guide groove 421, and the other end of the heat conduction member 500 can be attached to the first substrate 423 without folding, so as to transfer the heat of the wireless charging coil 300 to the first substrate 423, and then to the second substrate 424 and the third substrate 425.
[0053] It should be noted that with reference to Figure 4The heat dissipation piece 420 is arranged at the bottom of the second arrangement area 1400, the first substrate 423 can be placed vertically on the surface of the shell 1000, the second substrate 424 and the third substrate 425 are arranged on the two sides of the first substrate 423 to form the flow guide groove 421, the other end of the heat conduction member 500 is bent by 90 degrees and is attached to the first substrate 423, the heat of the wireless charging coil 300 is transmitted to the first substrate 423, and then is transmitted to the second substrate 424 and the third substrate 425.
[0054] In some embodiments, referring to Figure 3 A plurality of heat dissipation fins 422 are evenly arranged in the flow guide groove 421, the plurality of heat dissipation fins 422 are placed in parallel with the second substrate 424 and the third substrate 425, and the heat exchange area of the heat dissipation piece 420 is effectively increased. Specifically, the plurality of heat dissipation fins 422 further divide the large flow guide groove 421 in the heat dissipation piece 420 into a plurality of small flow guide grooves 421, so that the air flow flows towards the several flow guide grooves 421 in the heat dissipation piece 420 in the second arrangement area 1400, more temperature-lower air flows are guided to contact the first substrate 423, the second substrate 424, the third substrate 425 and the plurality of heat dissipation fins 422 more fully to achieve rapid heat exchange, and the heat is smoothly guided out of the air outlet channel 1100, and the heat dissipation efficiency and the charging efficiency are further improved.
[0055] In some embodiments, the heat conduction member 500 is made of graphene material or copper foil material or aluminum foil material, or can be made of other high-thermal-conductivity uniform-temperature materials, which are not limited here.
[0056] In some embodiments, referring to Figure 2 A buffer 600 is arranged between the heat conduction member 500 and the shell 1000 and between the heat dissipation piece 420 and the shell 1000.
[0057] It can be understood that the buffer 600 can protect the wireless charging coil 300 located above the heat conduction member 500, the power supply module 200 located below the heat conduction member 500 and the heat dissipation piece 420 from external impact and vibration, and improve the service life of the mobile power supply.
