[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] like Figure 1 and Figure 2 As shown, a power bank that is convenient for fast charging and heat dissipation includes a power bank body 1, a battery cell 11 located inside the power bank body 1, a heat conducting plate 21 located above the battery cell 11 and connected to the heat pipe 2, and air permeable plates 23 corresponding to the heat dissipation channel 22 are arranged on both sides of one end of the power bank body 1 away from the heat dissipation blades 13, an outer shell 24 is arranged on the outside of the heat dissipation channel 22 and is sleeved on the outside of the power bank body 1 and fixedly connected to the air permeable plate 23, a circuit board 12 electrically connected to the battery cell 11 is arranged on the other end of the heat pipe 2, and heat dissipation blades 13 are arranged on the end of the circuit board 12 away from the battery cell 11, and a heat dissipation channel 22 sleeved on the outside of the battery cell 11 is arranged on the outside of the heat conducting plate 21 and the heat dissipation blades 13.

[0026] In this embodiment, a heat pipe 2 is arranged on the battery cell 11 to connect the heat conducting plate 21 and the circuit board 12 at both ends. With the help of the good thermal conductivity of the heat pipe 2, the heat of the battery cell 11 and the circuit board 12 is transferred to the heat conducting plate 21. At the same time, with the help of the heat dissipation blades 13, the heat overflowing from the end of the circuit board 12 is transferred to the evenly distributed blades. After the device is erected, the hot air will rise in the heat dissipation channel 22, the internal air pressure will decrease, and the external cold air will be replenished into the heat dissipation channel 22 from the other end, thereby realizing air circulation, which can not only dissipate the heat of the heat conducting plate 21 and the heat dissipation blades 13, but also remove the hot air.

[0027] like Figure 3 and Figure 4 As shown, a plurality of evenly distributed extension plates 25 are provided on the side of the heat conducting plate 21 away from the battery cell 11 and are placed in the heat dissipation channel 22. The extension plate 25 is provided with a through hole 26 that penetrates the extension plate 25. The heat dissipation channel 22 includes an air inlet channel 27 close to the side of the extension plate 25 and an exhaust channel 28 located on the side of the battery cell 11 away from the air inlet channel 27. The air inlet channel 27 and the exhaust channel 28 are connected by an ascending channel 29 placed at one end of the heat dissipation blade 13. The outer sleeve of the heat pipe 2 is provided with a fixing sleeve 14 placed above the battery cell 11 and connected to the outer shell 24 by a bolt structure. The outer part of the circuit board 12 is provided with a metal shell 15 fixedly connected to the heat pipe 2 and the heat dissipation blade 13.

[0028] In this embodiment, the device should be used with the heat conducting plate 21 placed on the bottom side as much as possible, so that cold air can enter the air inlet channel 27 from the lower air permeable plate 23, and the cold air passes through the through hole 26 on the extension plate 25 to cool the heat conducting plate 21 and the heat pipe 2, while continuing to enter the rising channel 29 under the action of the pressure airflow. As the heat from the heat dissipation blades 13 dissipates, the gas temperature rises, and the hot air rises and enters the exhaust channel 28, thereby circulating the air inside the power bank to facilitate heat dissipation.

[0029] When in use, the power bank body 1 is stood up, and the heat conducting plate 21 is placed on the bottom side, and kept in a stable position; the device to be charged is connected to the output port of the power bank to start the charging process; during the charging process, cold air will enter the air inlet channel 27 from the end of the power bank body 1 away from the heat dissipation blade 13 through the air permeable plate 23, and the cold air passes through the through hole 26 on the extension plate 25 to cool the heat conducting plate 21 and the heat pipe 2, and the cold air continues to enter the rising channel 29 through the pressure effect, and as the heat dissipated by the heat dissipation blade 13, the gas temperature rises, and the hot air rises into the exhaust channel 28, thereby forming an internal air circulation and promoting the heat dissipation effect; during use, the power bank body 1 is kept sideways to ensure the best heat dissipation effect, and the power bank is avoided from being placed in a closed or poorly ventilated environment to avoid affecting the heat dissipation performance, and the temperature of the power bank is monitored to ensure that it operates within a safe range to avoid overheating. By following the above steps, the design features of the utility model can be effectively utilized to improve the heat dissipation performance of the power bank and ensure the safety and efficiency of the charging process.

[0030] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
