Description

Technical Field

[0002] Currently, while wireless charging power banks offer convenience for charging electronic devices, their heat dissipation issues cannot be ignored. During the charging process, especially at high power output, complex electrochemical reactions occur inside the battery, generating heat. If this heat cannot be dissipated promptly, the internal temperature of the power bank will continue to rise. When the temperature exceeds the safe tolerance range of the battery materials, it may trigger thermal runaway, causing serious safety accidents such as bulging, fire, or even explosion.

Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] The wireless charging power bank provided in this embodiment of the utility model, such as Figure 1As shown, it includes: a power supply body, a wireless charging coil 1 and a heat dissipation component. The wireless charging coil 1 is disposed on the power supply body, and the heat dissipation component includes: a heat conduction component and a fan component.

[0050] like Figure 6 and Figure 7 As shown, the fan assembly includes: an air inlet, an air outlet 2, and a fan 3;

[0051] The air inlet and air outlet 2 are respectively located on the housing of the power supply body;

[0052] The heat-conducting component is located inside the power supply body and is used to conduct the heat of the heat-generating device of the power supply body to the space between the air inlet and the air outlet 2.

[0053] The fan 3 is located inside the power supply unit and is used to create convection between the air inlet and the air outlet 2 to carry away the heat conducted between the air inlet and the air outlet 2 outside the power supply unit.

[0054] It should be noted that, as Figure 1 As shown, the wireless charging coil 1 is disposed on the front shell 8 of the power supply body; the air inlet can be opened on the side wall of the front shell 8 of the power supply body, and the air outlet 2 can be opened on the top wall of the front shell 8 of the power supply body; the heat conduction component is disposed inside the power supply body, and one end of it can be in heat conduction contact with the heat-generating device of the power supply body, and the other end can be located between the air inlet and the air outlet 2, so as to conduct the heat of the heat-generating device to the air inlet and the air outlet 2; wherein, the heat-generating device of the power supply body may include: battery 4 and circuit board 5; the fan 3 can be located between the air inlet and the air outlet 2 to form forced convection between the air inlet and the air outlet 2, for conducting heat to the air inlet and the air outlet 2. The heat from the heating elements is carried out of the power supply body, achieving effective heat dissipation for the wireless charging power bank. The air inlet and outlet 2 of the power supply body form a convection airflow channel. The forced convection created by the fan 3 between the air inlet and outlet 2 involves air entering through the air inlet and exiting through the outlet 2. This allows the heat from the heating elements conducted between the air inlet and outlet 2 to be carried out of the power supply body by the convection of the airflow. In other words, the fan 3's convection removes the heat from the heating elements carried by the heat-conducting components from the power supply body. This also contributes to the rapid heat dissipation of the wireless charging power bank.

[0055] In other words, the wireless charging power bank provided by this solution uses a heat-conducting component to transfer the heat from the heat-generating components of the power bank body to the air inlet and outlet 2 of the power bank body shell. A fan 3 then creates forced convection between the air inlet and outlet 2 of the power bank body shell to quickly remove the heat transferred to the air inlet and outlet 2 of the power bank body shell, thereby improving the heat dissipation effect of the wireless charging power bank and enabling effective heat dissipation. Simply put, this wireless charging power bank can effectively reduce the temperature of the wireless charging power bank during operation through the synergistic effect of the heat-conducting component and the fan component.

[0056] In this solution, the thermally conductive components include: thermally conductive parts and heat dissipation parts;

[0057] The heat sink is located between the air inlet and the air outlet 2;

[0058] The heat-conducting component is disposed between the heat-generating device and the heat-dissipating component, and is used to conduct the heat from the heat-generating device to the heat-dissipating component;

[0059] The convection generated by fan 3 is used to carry the heat conducted to the heat sink out of the power supply body.

[0060] It should be noted that the heat sink is located inside the power supply body, between the air inlet and outlet 2 of the power supply body shell, which is also located in the convection path of the fan 3. Of course, the heat sink serves as a heat dissipation carrier. The heat conduction component is located inside the power supply body, with one end in thermal contact with the heat-generating device and the other end in thermal contact with the heat sink. It is used to conduct the heat from the heat-generating device to the heat sink, and also to conduct the heat from the heat-generating device to the heat sink. The convection formed by the fan 3 is used to carry the heat conducted to the heat sink out of the power supply body. Of course, the heat conducted to the heat sink will be dissipated from the heat sink. The convection formed by the fan 3 is just used to carry this heat out of the power supply body. In other words, the heat conduction component includes a heat conduction part (i.e., the heat conduction component) and a heat dissipation part (i.e., the heat sink) to conduct the heat from the heat-generating device to the convection path of the fan 3 for heat dissipation. Then, the forced convection of the fan 3 carries the heat from the heat-generating device out of the power supply body, thereby helping to achieve effective heat dissipation of the wireless charging power bank.

[0061] Specifically, the heat-conducting component includes a heat-conducting plate;

[0062] like Figure 4 As shown, the heat-conducting plate is disposed on the battery 4 of the power supply body and is in thermal conduction cooperation with the circuit board 5 of the power supply body.

[0063] like Figure 8 As shown, the heat sink includes a heat sink 6;

[0064] like Figure 4As shown, the heat sink 6 is disposed on the heat conduction plate, and a heat dissipation structure is provided on it between the air inlet and the air outlet 2.

[0065] It should be noted that, as Figure 4 As shown, a heat-conducting plate can be placed on top of the battery 4 of the power supply body and cooperates with the circuit board 5 of the power supply body for thermal conduction, thus transferring the heat from the battery 4 and the circuit board 5 to the heat sink. The heat-conducting plate structure increases the heat conduction area, facilitating the transfer of more heat from the heat-generating components to the heat sink. Figure 4 As shown, the heat sink 6 can be disposed on top of the heat conduction plate, and its top is provided with a heat dissipation structure located between the air inlet and air outlet 2 of the power supply main body shell; of course, the heat conduction plate and the heat sink 6 can be stacked on top of the battery 4 in sequence; wherein, the heat sink adopts a plate-shaped structure and is stacked on the heat conduction plate in order to receive the heat brought by the heat conduction plate to the maximum extent, and can also increase the heat dissipation area and further enhance the heat dissipation effect. In addition, the heat sink is also provided with a heat dissipation structure located in the convection path of the fan 3, which facilitates the maximum removal of heat from the heat sink; that is to say, the heat conduction plate and the heat sink are designed in this way to help improve the heat dissipation effect of the wireless charging power bank.

[0066] Furthermore, such as Figure 9 As shown, the heat-conducting plate includes a heat spreader 7. The heat spreader 7 can be a VC heat spreader; the VC heat spreader has excellent thermal conductivity and can quickly and evenly distribute the heat generated by the battery 4 and the circuit board 5 to the heat sink 6, thus accelerating the heat transfer of the battery 4 and the circuit board 5 to the heat dissipation structure of the heat sink 6.

[0067] In other words, the heat dissipation components of this wireless charging power bank, through the synergistic heat dissipation mechanism of the VC heat dissipation plate, heat sink 6 and fan 3 (i.e. synergistic heat dissipation effect), can effectively dissipate heat from the wireless charging power bank, thus continuously removing the heat generated by the battery and keeping the battery working at a suitable temperature.

[0068] Furthermore, as mentioned above, the air inlet is located on the side wall of the front housing 8 of the power supply unit;

[0069] like Figure 7 As shown, the air outlet 2 is located on the top wall of the front shell 8 of the power supply body;

[0070] The heat sink 6 is located inside the front shell 8, and its heat dissipation structure is located inside the air inlet.

[0071] like Figure 6 As shown, fan 3 is located at air outlet 2. Wherein, as... Figure 1 As shown, the air inlet is located on the side wall of the front housing 8 of the power supply unit, as... Figure 7As shown, the air outlet 2 is located on the top wall of the front shell 8 of the power supply body. Of course, this side wall of the front shell 8 is adjacent to the top wall. That is to say, the air inlet and the air outlet 2 are located on different adjacent shell walls of the front shell 8. This helps to shorten the convection path of the fan 3, avoid the negative pressure effect generated by the fan 3 being too obvious, prevent it from affecting the life and speed of the fan 3, and ensure that the fan 3 can form forced convection between the air inlet and the air outlet 2.

[0072] In this plan, such as Figure 1 and Figure 2 As shown, the air inlet includes: a first air inlet 9, a second air inlet 10 and a third air inlet 11, which are respectively opened on the first short side wall, the first long side wall and the second long side wall of the front shell 8.

[0073] The heat dissipation structure includes a first heat dissipation structure, a second heat dissipation structure and a third heat dissipation structure, and each of them is located inside the first air inlet 9, the second air inlet 10 and the third air inlet 11.

[0074] Fan 3 is located in the middle of the first heat dissipation structure, the second heat dissipation structure and the third heat dissipation structure.

[0075] It should be noted that, as Figure 1 As shown, the first air inlet 9 can be opened on the left side wall of the front shell 8, and the second air inlet 10 can be opened on the rear side wall of the front shell 8, as shown. Figure 2 As shown, the third air inlet 11 can be opened on the front side wall of the front housing 8; of course, the power supply main body housing has multiple air inlets at suitable distances to prevent the fan 3 from generating negative pressure inside the power supply main body; such as Figure 8 As shown, the first, second, and third heat dissipation structures are located inside the first air inlet 9, the second air inlet 10, and the third air inlet 11, respectively. The first heat dissipation structure can be equivalent to the left-side heat dissipation structure in the convection path of the fan 3, the second heat dissipation structure can be equivalent to the rear-side heat dissipation structure in the convection path of the fan 3, and the third heat dissipation structure can be equivalent to the front-side heat dissipation structure in the convection path of the fan 3. The fan 3 can be located in the middle of the left-side, rear-side, and front-side heat dissipation structures, that is, the downward projection of the air outlet 2 can be located in the middle of the left-side, rear-side, and front-side heat dissipation structures, so as to carry the heat from the above three heat dissipation structures out of the power supply body. In other words, multiple side walls of the power supply body shell (i.e., the front shell 8) are provided with air inlets, which increases the air intake area. Moreover, the heat dissipation plate 6 is provided with a heat dissipation structure inside each air inlet. This not only helps to improve the convection effect of the fan 3, but also helps to improve the heat dissipation effect of the wireless charging power bank.

[0076] Specifically, such as Figure 8 As shown, the first heat dissipation structure includes: a plurality of first heat dissipation strips 12, which are arranged side by side on the heat dissipation plate 6 inside the first air inlet 9, as shown. Figure 1As shown, the inner side of the first air inlet 9 is divided into multiple first air inlet channels 13 arranged in parallel and perpendicular to the first short sidewall of the front shell 8.

[0077] like Figure 8 As shown, the second heat dissipation structure includes: multiple second heat dissipation strips 14, which are arranged side by side on the heat dissipation plate 6 inside the second air inlet 10, as shown. Figure 1 As shown, the inner side of the second air inlet 10 is divided into a plurality of second air inlet channels 15 arranged in parallel and perpendicular to the first long sidewall of the front shell 8.

[0078] like Figure 8 As shown, the third heat dissipation structure includes: multiple third heat dissipation strips 16, which are arranged side by side on the heat dissipation plate 6 inside the third air inlet 11, as shown. Figure 2 As shown, the inner side of the third air inlet 11 is divided into multiple third air inlet channels 17 arranged in parallel and perpendicular to the second long sidewall of the front shell 8.

[0079] It should be noted that, as Figure 8 As shown, multiple first heat dissipation strips 12 are arranged side by side on the heat dissipation plate 6, and are located inside the first air inlet 9 of the front shell 8, and perpendicular to the first short sidewall of the front shell 8, as shown. Figure 1 and Figure 8 As shown, the inner side of the first air inlet 9 of the front shell 8 is divided into multiple first air inlet channels 13 arranged in parallel, and the multiple first air inlet channels 13 are perpendicular to the first short sidewall of the front shell 8; of course, the top of the multiple first heat dissipation strips 12 can contact the top wall of the front shell 8 to ensure that the inner side of the first air inlet 9 of the front shell 8 can be divided into multiple first air inlet channels 13; wherein, using the multiple first heat dissipation strips 12 as the spacing structure of the multiple first air inlet channels 13 inside the first air inlet 9 not only makes the first heat dissipation structure more compact inside the first air inlet 9, but also improves the air intake effect of the first air inlet 9, thereby helping to improve the heat dissipation effect of the first heat dissipation structure;

[0080] like Figure 8 As shown, multiple second heat dissipation strips 14 are arranged side by side on the heat dissipation plate 6, and are located inside the second air inlet 10 of the front shell 8, and perpendicular to the first long side wall of the front shell 8, as shown. Figure 1 and Figure 8As shown, the inner side of the second air inlet 10 of the front shell 8 is divided into a plurality of parallel second air inlet channels 15, and the plurality of second air inlet channels 15 are perpendicular to the first long sidewall of the front shell 8; of course, the top of the plurality of second heat dissipation strips 14 can contact the top wall of the front shell 8 to ensure that the inner side of the second air inlet 10 of the front shell 8 can be divided into a plurality of second air inlet channels 15; wherein, using the plurality of second heat dissipation strips 14 as the spacing structure of the plurality of second air inlet channels 15 inside the second air inlet 10 not only makes the second heat dissipation structure more compact inside the second air inlet 10, but also improves the air intake effect of the second air inlet 10, thereby helping to improve the heat dissipation effect of the second heat dissipation structure;

[0081] Similarly, such as Figure 8 As shown, multiple third heat dissipation strips 16 are arranged side by side on the heat dissipation plate 6, and are located inside the third air inlet 11 of the front shell 8, and perpendicular to the second long side wall of the front shell 8, as shown. Figure 2 and Figure 8 As shown, the inner side of the third air inlet 11 of the front shell 8 is divided into multiple parallel third air inlet channels 17, and the multiple third air inlet channels 17 are perpendicular to the second long sidewall of the front shell 8; of course, the tops of the multiple third heat dissipation strips 16 can contact the top wall of the front shell 8, ensuring that the inner side of the third air inlet 11 of the front shell 8 can be divided into multiple third air inlet channels 17; wherein, using the multiple third heat dissipation strips 16 as the spacing structure of the multiple third air inlet channels 17 inside the third air inlet 11 not only makes the third heat dissipation structure more compact inside the third air inlet 11, but also improves the air intake effect of the third air inlet 11, thereby helping to improve the heat dissipation effect of the third heat dissipation structure; of course, these first air inlet channels 13, second air inlet channels 15 and third air inlet channels 17 are equivalent to side air inlet channels;

[0082] In addition, such as Figure 8As shown, among the multiple first heat sinks 12 arranged side by side, the first heat sink 12 located in the middle is longer, while the first heat sinks 12 located on both sides are shorter, so that the multiple first heat sinks 12 can appear as a triangle. Furthermore, the multiple first heat sinks 12 are separated from the multiple second heat sinks 14 by a first spacer edge, the multiple first heat sinks 12 are separated from the multiple third heat sinks 16 by a second spacer edge, and the multiple second heat sinks 14 are further separated from the multiple third heat sinks 16 by a third spacer edge. The first heat sink 12 located in the middle... The inner end of the second heat sink 14 located in the middle and the inner end of the third heat sink 16 located in the middle can form a circle. The fan 3 is located above the circle and concentric with the circle. In this way, through the convection effect of the fan 3, the outside air is drawn in from each of the first air inlet channel 13, the second air inlet channel 15 and the third air inlet channel 17 and then drawn out from the air outlet 2. In this process, the heat on each of the first heat sink 12, the second heat sink 14 and the third heat sink 16 is also carried away, thereby further improving the heat dissipation effect of the wireless charging power bank.

[0083] In other words, such as Figure 8 As shown, each heat dissipation structure of the heat sink 6 includes: multiple heat dissipation strips arranged in parallel on the heat sink 6 and located on the inner side of the air inlet corresponding to the front shell 8. Moreover, the multiple heat dissipation strips are designed in this way, which also divides the inner side of the front shell 8 corresponding to the air inlet into multiple air inlet channels arranged in parallel. This not only enhances the convection effect of the fan 3, but also helps to further improve the heat dissipation effect of the wireless charging power bank.

[0084] Furthermore, such as Figure 7 As shown, air outlet 2 is a circular air outlet;

[0085] The top wall of the front shell 8 has an annular recess 18 around the circular air outlet;

[0086] like Figure 1 and Figure 4 As shown, the wireless charging ring 1 is disposed in the recess 18 on the top wall of the front shell 8, and is located above the circular air outlet, forming an air outlet channel 24 between the wireless charging ring 1 and the recess 18; wherein, as Figure 3 As shown, the diameter of the wireless charging coil 1 is larger than the inner diameter of the recess 18 and smaller than the outer diameter of the recess 18.

[0087] like Figure 4 and Figure 5 As shown, fan 3 is positioned between the wireless charging coil 1 and the circular air outlet; fan 3 is a centrifugal fan.

[0088] It should be noted that, as Figure 7As shown, the circular air outlet on the top wall of the front shell 8 is concentric with the circle mentioned above; the recess 18 on the top wall of the front shell 8 surrounds the outer side of the circular air outlet, and the inner periphery of the recess 18 is lower than the outer periphery. Therefore, the inner periphery of the recess 18 is the circular air outlet; Figure 4 As shown, the wireless charging ring 1 can be positioned above the recess 18 on the top wall of the front shell 8, and the wireless charging ring 1 is correspondingly located above the circular air outlet, forming an air outlet channel 24 between the wireless charging ring 1 and the recess 18; wherein, as Figure 3 As shown, the diameter of the wireless charging coil 1 is larger than the inner diameter of the recess 18 and smaller than the outer diameter of the recess 18, ensuring that the air outlet channel 24 can smoothly dissipate air and heat, avoiding obstruction by the wireless charging coil 1; Figure 4 As shown, fan 3 is positioned between the wireless charging coil 1 and the circular air outlet, and it is a centrifugal fan; that is, fan 3 can be located above the circular air outlet and concentric with it; thus, under the forced convection of fan 3, as... Figure 4 As shown, outside air flows in through the air intake channels of each air inlet of the front shell 8, then flows in axially through the fan 3 and flows out radially through the fan 3, that is, it flows out through the air outlet channel 24. This not only removes heat from each heat sink, but also dissipates heat from the wireless charging coil 1. At the same time, this structure is also compactly integrated. Of course, the top wall of the front shell 8 has a recess 18 for the wireless charging coil 1, which avoids the wireless charging coil 1 from appearing obtrusive on the top wall of the front shell 8, and also helps to dissipate heat from the wireless charging coil 1. Among them, such as Figure 6 As shown, a positioning protrusion 26 is provided on the recess 18 on the top wall of the front shell 8, such as... Figure 10 As shown, the bottom of the wireless charging ring 1 is provided with a positioning groove 27 for cooperating with the positioning protrusion 26, so that the wireless charging ring 1 is positioned and installed on the recess 18 on the top wall of the front shell 8.

[0089] Furthermore, such as Figure 7 As shown, the top wall of the front shell 8 is provided with an annular guide protrusion 19 surrounding the recess 18; wherein, the guide protrusion 19 and the recess 18 are smoothly transitioned. As shown in the figure... Figure 6 and Figure 7 As shown, the top wall of the front shell 8 is provided with an annular flow guide protrusion 19, which surrounds the outer side of the recess 18; wherein, the flow guide protrusion 19 and the outer periphery of the recess 18 are smoothly transitioned, which facilitates the heat on each heat sink to be carried out of the power supply body, and thus facilitates the heat on each heat sink to be discharged out of the power supply body.

[0090] More specifically, such as Figure 5 As shown, the outer wall of the recess 18 and the inner wall of the guide protrusion 19 are smooth arc surfaces. Wherein, as... Figure 5As shown, the cross-section of the outer wall of the recess 18 and the inner wall of the guide protrusion 19 can be a smooth arc surface with an arc of 90°, while the inner wall of the guide protrusion 19 can be equivalent to a vertical surface. In this way, the outlet end of the air outlet channel 24 is vertically oriented, which allows the heat of each heat sink to be discharged upward after passing through the air outlet channel 24, preventing the heat of the heat sink from radiating to the surroundings after passing through the air outlet channel 24. Of course, this also facilitates heat dissipation for the wireless charging coil 1.

[0091] In other words, the wireless charging power bank in this solution is equipped with a fan, which can create forced convection when running to quickly remove the heat generated inside the power bank; the heat sink further enhances the heat dissipation effect by increasing the heat dissipation area; the VC heat dissipation plate has good thermal conductivity and can quickly and evenly distribute the heat generated by the battery to the heat sink, accelerating the heat transfer to the heat sink.
