Description

Technical Field

[0001] This application relates to the field of energy storage equipment technology, and in particular to a heat dissipation structure and energy storage equipment. Background Technology

[0002] Energy storage devices are devices that can store electrical energy and provide power to electrical devices (such as mobile phones, lamps, etc.). They are mainly used to power devices in environments without power, thus providing considerable convenience for outdoor operations and have been widely used.

[0003] In energy storage devices, there may be multiple circuit boards or components that need to be cooled. Cooling multiple circuit boards or components may lead to the problem of "one cannot be cooled while another is cooled". If fans need to be deployed in multiple different locations for better heat dissipation, it may be necessary to deploy fans in multiple different locations. This is not conducive to the miniaturization of energy storage devices. In addition, deploying fans in different locations can also easily increase noise and cost. Summary of the Invention

[0004] The embodiments of this application aim to provide a heat dissipation structure and energy storage device, so as to at least improve the problem that energy storage devices need to deploy fans in multiple different locations.

[0005] In order to solve the above-mentioned technical problems, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, embodiments of this application provide a heat dissipation structure, the heat dissipation structure including a first shroud, a second shroud, and an exhaust fan; the first shroud has a first air cavity, a first air inlet, a first air outlet, a first turning port, and a second turning port; the first air inlet and the first air outlet are distributed opposite to each other along a first direction and are both connected to the first air cavity; the first air cavity defines a first region and a second region, the first region is used to accommodate a first component to be scald, and the first turning port and the second turning port are both connected to the second region in a second direction; the second turning port is used to align the second component to be scald with the first shroud in a third direction; the second turning port is aligned with the first air inlet in a third direction and is positioned before and after the first turning port in the first direction. The second air hood is positioned vertically above and below the first air hood in a first direction and directly faces the second region. The second air hood has a second air cavity for accommodating the third heat-dissipating component, and a second air inlet and a second air outlet both connected to the second air cavity. The second air inlet faces the same direction as the first air inlet, and the second air outlet is connected to the first turning port in a second direction. The suction fan is located at the first air outlet. The suction fan is used to draw in external airflow from the first air inlet, the second air inlet, and the second turning port and to discharge it from the first air outlet to dissipate heat from the first heat-dissipating component, the second heat-dissipating component, and the third heat-dissipating component. The heat generated by the second heat-dissipating component and the third heat-dissipating component is less than the heat generated by the first heat-dissipating component. This application forms three heat dissipation airflow channels by combining a first wind shield, a second wind shield, and various air inlets and outlets with an intake fan located only on one side of the first wind shield. It eliminates the need to deploy fans in all directions to dissipate heat from the first, second, and third components to be cooled at different locations. Compared to deploying different fans in multiple directions, this reduces costs and noise, and also helps to reduce the size of the energy storage device, thus facilitating the miniaturization of the equipment.

[0007] In some embodiments, the first hood includes a first top plate and a first side plate for enclosing and forming the first air cavity; the first top plate supports the second hood and has the first turning opening, the first top plate is recessed towards the first air cavity to form a trapezoidal structural plate, the first air inlet and the first turning opening are respectively disposed on both sides of the trapezoidal structural plate in a first direction; the first side plate and the first top plate are connected vertically in a second direction, the extension length of the first side plate in the first direction is less than the extension length of the first top plate in the first direction; the trapezoidal structural plate is spaced apart from the first side plate in a third direction to form the second turning opening. This allows the heat emitted by the second heat-dissipating component to be drawn into the second turning opening from the third direction, and after entering the second turning opening, under the blocking effect of the trapezoidal structural plate, the heat emitted by the second heat-dissipating component is turned in the first direction and enters the second region of the first air cavity.

[0008] In some embodiments, the first side plate is provided with a guide plate on the side facing the first air inlet. The guide plate extends in a direction away from the first air cavity and is used to extend to the second heat-dissipating component. The guide plate is used to guide the heat flow of the second heat-dissipating component into the second deflection port. The guide plate abuts against the second heat-dissipating component, thereby forming an airflow channel, and part of the airflow channel is formed by the second heat-dissipating component to enhance the heat dissipation effect on the second heat-dissipating component.

[0009] In some embodiments, the first shroud further includes a second side plate, which is connected to the first top plate and disposed opposite to the first side plate in the third direction; a first radiator of the first component to be scald is disposed within the first air cavity and close to the second side plate, and a second radiator of the first component to be scald is disposed within the first air cavity and close to the trapezoidal structural plate. This concentrates the airflow between the first and second radiators, reducing the airflow resistance; and the first and second radiators can dissipate heat through the first shroud.

[0010] In some embodiments, the trapezoidal structural plate includes a first connecting plate, a second connecting plate, and a third connecting plate; the first connecting plate is connected to the first top plate and extends toward the first air cavity, the second connecting plate is connected to the first connecting plate and extends toward the first side plate, and the third connecting plate is connected to the second connecting plate and extends toward the first air cavity. Due to the blocking and guiding effect of the third connecting plate, the hot airflow carrying heat emitted by the second heat-dissipating component is redirected in a first direction and enters the second region of the first air cavity.

[0011] In some embodiments, the second hood includes a second top plate, two third side plates, and an inclined plate for enclosing and forming the second air cavity; the second top plate and the first hood are distributed vertically in the second direction; the two third side plates are disposed opposite each other, with one side of each third side plate connected to the second top plate and the other side of each third side plate abutting against the side wall of the first hood where the first turning opening is located; the four sides of the inclined plate are respectively connected to the second top plate, the two third side plates, and the side wall of the first hood where the first turning opening is located; the projection of the inclined plate onto the first hood covers at least half of the area of ​​the first turning opening, and the height of the inclined plate from the second hood in the second direction gradually decreases in the direction in which the external airflow enters the second air cavity. This allows the inclined plate to guide the airflow flowing into the first turning opening from the second air cavity, reducing airflow resistance. The compression and guiding effect of the inclined plate on the airflow allows the hot airflow in the second air cavity to be better introduced into the first air cavity from the first turning opening.

[0012] In some embodiments, the second fan cover is provided with a snap-fit ​​part, and the first fan cover is provided with a snap-fit ​​groove, and the snap-fit ​​part snaps into the snap-fit ​​groove. This snap-fit ​​connection between the second fan cover and the first fan cover reduces the number of fasteners, lowers costs, and simplifies the connection steps between the first and second fan covers.

[0013] Secondly, embodiments of this application provide an energy storage device, the energy storage device including a shell, a first circuit board, a second circuit board, a third circuit board, a first heat-dissipating component, a second heat-dissipating component, a third heat-dissipating component, and a heat dissipation structure as described in any embodiment of the first aspect; the shell has a first ventilation opening and a second ventilation opening disposed opposite to each other along a first direction, the first ventilation opening being directly opposite to the first air inlet, the second air inlet, and the second turning outlet, and the suction fan being directly opposite to the second ventilation opening; the first shroud is mounted on the first circuit board; the second circuit board is disposed opposite to the first circuit board in the first direction and disposed within the second shroud; the first heat-dissipating component is disposed on the first circuit board and housed within the first region; the third heat-dissipating component is disposed on the second circuit board and housed within the second shroud; the third circuit board is disposed on the same side of the first circuit board and the second circuit board; the second heat-dissipating component is disposed on the side of the third circuit board facing the first shroud; the heat generation of the second heat-dissipating component and the third heat-dissipating component is less than the heat generation of the first heat-dissipating component. This enables heat dissipation for the first circuit board substrate, the second circuit board substrate, the third circuit board substrate, the first heat-dissipating component, the second heat-dissipating component, and the third heat-dissipating component.

[0014] In some embodiments, the first heat-dissipating component includes a plurality of first heating elements, a first heat sink, and a second heat sink, all disposed on the first circuit board, wherein both the first and second heat sinks conduct heat to the first heating elements; the third heat-dissipating component includes a plurality of second heating elements and a third heat sink, all disposed on the second circuit board, wherein the third heat sink conducts heat to the second heating elements, and the heat generated by the plurality of second heating elements is less than that of the plurality of first heating elements; the second heat-dissipating component includes a panel and a third heating element located on the panel, wherein the panel extends from the first vent toward the second vent in the first direction, and the heat generated by the third heating element is less than that of the plurality of first heating elements. The first and second heat sinks conduct heat to the first heating elements, enhancing the heat dissipation effect on the first heating elements; the third heat sink conducts heat to the second heating elements, enhancing the heat dissipation effect on the second heating elements; and the heat dissipation structure can dissipate heat from the panel and the third heating element on the panel.

[0015] In some embodiments, the energy storage device further includes a plurality of fourth heating elements, which are arranged in a row along the first direction and facing the second region. The suction fan is used to carry the heat from the fourth heating elements into the second region when external airflow enters the housing from the first vent. When the second deflector draws in gas, an airflow is formed at the fourth heating elements to dissipate heat from them.

[0016] The above description is merely an overview of the technical solution of this application.

[0042] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0043] Firstly, please refer to Figure 1 This application provides a heat dissipation structure 100, which includes a first shroud 1, a second shroud 2, and an exhaust fan 3. The heat dissipation structure 100 is used to dissipate heat from heat-generating components within an energy storage device 200.

[0044] For the first wind shield 1 mentioned above, please refer to Figures 1 to 3 The first air hood 1 has a first air cavity 11, a first air inlet 12, a first air outlet 13, a first turning port 14, and a second turning port 15. The first air inlet 12 and the first air outlet 13 are distributed relative to each other along the first direction X and are both connected to the first air cavity 11. The first air cavity 11 defines a first region 111 and a second region 112. Please refer to [link / reference]. Figure 4 and Figure 5 The first region 111 is used to accommodate the first heat-dissipating component 250, and both the first turning port 14 and the second turning port 15 are connected to the second region 112 in the second direction Y. Please refer to [link / reference]. Figure 4 and Figure 5 The second turning port 15 is used to face the second heat dissipation component 260 arranged parallel to the first air shroud 1 in the third direction Z. The second turning port 15 is arranged parallel to the first air inlet 12 in the third direction Z, and is arranged before and after the first turning port 14 in the first direction X. The first direction X, the second direction Y, and the third direction Z intersect or are perpendicular to each other. Optionally, the first air shroud 1 is formed by folding sheet material, such as cardboard, plastic sheet, or metal sheet.

[0045] For the second hood 2 mentioned above, please refer to Figures 1 to 3The second shroud 2 is positioned vertically above the first shroud 1 in the first direction X and faces the second region 112. Please refer to [link / reference]. Figure 4 The second shroud 2 has a second air cavity 21 for accommodating the third heat-dissipating component 270, and a second air inlet 22 and a second air outlet 23 both connected to the second air cavity 21. The second air inlet 22 faces the same direction as the first air inlet 12, and the second air outlet 23 connects to the first turning port 14 in the second direction Y. It can be understood that airflow enters the second air cavity 21 from the second air inlet 22, and the airflow finally flows from the second air outlet 23 to the second region 112. Optionally, the second shroud 2 is formed by folding sheet material, such as cardboard, plastic sheet, or metal sheet.

[0046] For the above-mentioned suction fan 3, please refer to Figure 1 The suction fan 3 is located at the first air outlet 13. When the suction fan 3 draws air in, it creates a negative pressure in the first air chamber 11, causing external gas to flow into the first air chamber 11 from the first air inlet 12, the first turning port 14, and the second turning port 15, generating airflow. Meanwhile, the gas in the second air chamber 21 flows into the second region 112 from the first turning port 14, creating a negative pressure in the second air chamber 21, causing external gas to flow sequentially from the second air inlet 22 through the second air chamber 21, the first turning port 14, the second region 112, and the first air outlet 13, generating airflow. In other words, the suction fan 3 is used to draw in external airflow from the first air inlet 12, the second air inlet 22, and the second turning port 15, and then out through the first air outlet 13. The first region 111 is used to accommodate the first heat-dissipating component 250, the second turning port 15 is used to face the second heat-dissipating component 260, and the second air cavity 21 accommodates the third heat-dissipating component 270, thereby dissipating heat for the first heat-dissipating component 250, the second heat-dissipating component 260, and the third heat-dissipating component 270. The heat generated by the second heat-dissipating component 260 and the third heat-dissipating component 270 is less than that of the first heat-dissipating component 250.

[0047] It is understood that this application, through the structural design of the first shroud 1 and the second shroud 2, and the planning of each air inlet and outlet, enables the suction fan 3 to form three heat dissipation airflow channels during operation. First heat dissipation airflow channel: External airflow enters the first region 111 of the first air chamber 11 from the first air inlet 12 along the first direction X, and finally flows out of the channel of the first shroud 1 from the first air outlet 13. Second heat dissipation airflow channel: External airflow enters the second air chamber 21 from the second air inlet 22 along the first direction X, then flows into the second region 112 of the second air chamber 21 from the first turning port 14 along the second direction Y, and finally flows out of the channel of the first shroud 1 from the first air outlet 13 along the first direction X. Third heat dissipation airflow channel: External airflow enters the second region 112 of the first air chamber 11 from the second turning port 15 along the third direction Z, and finally flows out of the channel of the first shroud 1 from the first air outlet 13 along the first direction X. Thus, the airflow direction remains constant in the first heat dissipation airflow channel, while the airflow direction changes in the second and third heat dissipation airflow channels. Therefore, the first heat dissipation airflow channel has a better heat dissipation effect compared to the second heat dissipation airflow channel. Figure 1 In the diagram, the dashed lines with arrows represent the flow paths of the airflow.

[0048] It is worth noting that the heat generated by the second heat-dissipating component 260 and the third heat-dissipating component 270 is less than that of the first heat-dissipating component 250, meaning that the first heat-dissipating component 250 generates the most heat. The first heat-dissipating component 250 is placed in the first region 111 of the first air cavity 11, meaning it is cooled by the first heat dissipation airflow channel. The second and third heat dissipation airflow channels cool the second heat-dissipating component 260 and the third heat-dissipating component 270 respectively. This allows for targeted cooling of different heat-dissipating components based on their heat generation, resulting in more consistent temperatures and improving the problem of uneven heat dissipation.

[0049] Furthermore, this application can form the aforementioned three heat dissipation airflow channels by combining the first shroud 1, the second shroud 2, and various air inlets and outlets with an intake fan 3 located only on one side of the first shroud 1. It does not require deploying fans in all directions to dissipate heat on the first heat-dissipating component 250, the second heat-dissipating component 260, and the third heat-dissipating component 270 in different locations. That is, compared to deploying different fans in multiple directions, it can reduce costs, reduce noise, and help reduce the size of the energy storage device 200, which is conducive to the miniaturization of the device.

[0050] For the specific structure of the first wind shield 1 mentioned above, please refer to [link / reference]. Figure 2 and Figure 3In some embodiments, the first hood 1 includes a first top plate 1a, a first side plate 1b, and a second side plate 1c for enclosing and forming a first air cavity 11. The first top plate 1a supports the second hood 2 and has a first turning opening 14. The first side plate 1b and the second side plate 1c are respectively connected to the two ends of the first top plate 1a along the third direction Z, and are arranged opposite to each other along the third direction Z, thereby enclosing and forming the first air cavity 11. A first air inlet 12 and a first air outlet 13, distributed in a first direction X, are respectively disposed on both sides of the first top plate 1a along the first direction X. It can be understood that the first side plate 1b and the first top plate 1a are vertically connected in the second direction Y.

[0051] In one embodiment, please refer to Figure 2 and Figure 3 The first top plate 1a is recessed towards the first air cavity 11 to form a trapezoidal structural plate 1a1. The first air inlet 12 and the first turning port 14 are respectively disposed on both sides of the trapezoidal structural plate 1a1 in the first direction X. The extension length of the first side plate 1b in the first direction X is less than the extension length of the first top plate 1a in the first direction X. The trapezoidal structural plate 1a1 is spaced apart from the first side plate 1b in the third direction Z to form a second turning port 15. In this way, when the suction fan 3 draws air, the heat emitted by the second heat-dissipating component 260 can be drawn into the second turning port 15 from the third direction Z. After entering the second turning port 15, under the blocking effect of the trapezoidal structural plate 1a1, the heat emitted by the second heat-dissipating component 260 is turned in the first direction X and enters the second region 112 of the first air cavity 11.

[0052] In one embodiment, please refer to Figure 4 and Figure 5 The first radiator 252 of the first heat-dissipating component 250 is tightly disposed within the first air cavity 11 and close to the second side plate 1c. The second radiator 253 of the first heat-dissipating component 250 is disposed within the first air cavity 11 and close to the trapezoidal structural plate 1a1. This concentrates the airflow between the first radiator 252 and the second radiator 253, reducing the airflow resistance. Furthermore, the first radiator 252 and the second radiator 253 can dissipate heat through the first shroud 1.

[0053] In some embodiments, please refer to Figures 3 to 5The first side plate 1b has a guide plate 1b1 on the side facing the first air inlet 12. The guide plate 1b1 extends in the direction opposite to the first air cavity 11 and extends to the second heat-dissipating component 260. The guide plate 1b1 is used to guide the heat flow of the second heat-dissipating component 260 into the second turning port 15. Exemplarily, the end of the first side plate 1b adjacent to the first air inlet 12 is bent in the opposite direction of the third direction Z to form the guide plate 1b1. The guide plate 1b1 abuts against the second heat-dissipating component 260, thereby forming an airflow channel, and part of the airflow channel is formed by the second heat-dissipating component 260 to enhance the heat dissipation effect on the second heat-dissipating component 260. Optionally, the guide plate 1b1 is perpendicular to other parts of the first side plate 1b.

[0054] In some embodiments, please refer to Figure 2 and Figure 3 The trapezoidal structural plate 1a1 includes a first connecting plate 1a11, a second connecting plate 1a12, and a third connecting plate 1a13. The first connecting plate 1a11 connects to the first top plate 1a and extends towards the first air cavity 11. The second connecting plate 1a12 connects to the first connecting plate 1a11 and extends towards the first side plate 1b. The third connecting plate 1a13 connects to the second connecting plate 1a12 and extends towards the first air cavity 11. That is, the trapezoidal structural plate 1a1 is Z-shaped, and the included angle between the two plates of the trapezoidal structural plate 1a1 is a right angle.

[0055] Understandably, when the suction fan 3 is working, the hot airflow carrying the heat emitted by the second heat-dissipating component 260 is drawn into the second turning port 15 from the third direction Z. Due to the blocking and guiding effect of the third connecting plate 1a13, the hot airflow carrying the heat emitted by the second heat-dissipating component 260 turns to the first direction X and enters the second region 112 of the first air cavity 11.

[0056] In some embodiments, please refer to Figure 2 and Figure 3 The second hood 2 includes a second top plate 2a, two third side plates 2b, and an inclined plate 2c for enclosing and forming a second air cavity 21. The second top plate 2a and the first hood 1 are vertically distributed in the second direction Y. The two third side plates 2b are arranged opposite each other, with one side of each third side plate 2b connected to the second top plate 2a, and the other side of each third side plate 2b abutting against the side wall of the first hood 1 where the first turning opening 14 is located. The four sides of the inclined plate 2c are respectively connected to the second top plate 2a, the two third side plates 2b, and the side wall of the first hood 1 where the first turning opening 14 is located. The second air inlet 22 is arranged opposite the inclined plate 2c along the first direction X, and the second air outlet 23 is arranged opposite the second top plate 2a along the second direction Y. This allows airflow to enter the second air cavity 21 from the second air inlet 22 along the first direction X, and then flow out of the second air outlet 23 along the second direction Y.

[0057] In some embodiments, please refer to Figure 6 The projection of the inclined plate 2c onto the first shroud 1 covers at least half of the area of ​​the first turning port 14. The height of the inclined plate 2c from the second shroud 2 in the second direction Y gradually decreases in the direction in which the external airflow enters the second air cavity 21. For example, the inclined plate 2c extends inclinedly towards the first shroud 1 from the connection point with the second top plate 2a, so that the inclined plate 2c has a guiding effect on the airflow flowing into the first turning port 14 from the second air cavity 21, thereby reducing airflow resistance. Figure 6 In the diagram, the dashed lines with arrows represent the flow paths of the airflow.

[0058] It is worth noting that when the suction fan 3 is working, external airflow enters the second air cavity 21 through the second air inlet 22, and the hot airflow carrying the heat of the third heat-dissipating component 270 flows within the second air cavity 21. Since only the first air outlet 13 serves as the airflow outlet for the entire heat dissipation structure 100 in this application, the hot airflow carrying the heat of the third heat-dissipating component 270 needs to enter the first air cavity 11. The compression and guiding effect of the inclined plate 2c allows the hot airflow in the second air cavity 21 to be better introduced into the first air cavity 11 from the first turning port 14. Furthermore, the projection of the inclined plate 2c onto the first fan shroud 1 covers at least half of the area of ​​the first turning port 14, which is also to allow the inclined plate 2c to introduce the hot airflow in the second air cavity 21 into the first turning port 14 to a greater extent. Here, the projection of the inclined plate 2c onto the first fan shroud 1 refers to the projection of the inclined plate 2c onto the first fan shroud 1 along the second direction Y.

[0059] In some embodiments, please refer to Figure 6 The heat dissipation structure 100 also includes a sealing plate 4, which is disposed on the first shroud 1 and is positioned opposite to the first shroud 1 along the second direction Y. Exemplarily, the sealing plate 4 is positioned opposite to the first top plate 1a, and the edge of the sealing plate 4 is adjacent to the first side plate 1b and the second side plate 1c. Thus, the first top plate 1a, the first side plate 1b, the second side plate 1c, and the sealing plate 4 together form a rectangular cylindrical shape with openings at both ends, increasing the airtightness of the first air cavity 11 and enhancing the heat dissipation effect on the first heat-dissipating component 250; enhancing the suction effect on the first turning port 14 and the second turning port 15, thereby enhancing the heat dissipation effect on the second heat-dissipating component 260 and the third heat-dissipating component 270. See [link to relevant documentation]. Figure 7 The sealing plate 4 includes a folded edge 41, which is bent toward the suction fan 3 and abuts against the suction fan 3, thereby improving the problem that the gap between the inner wall of the first air outlet 13 and the suction fan 3 reduces the suction effect of the suction fan 3 on the first air chamber 11. Optionally, the sealing plate 4 is made of insulating material.

[0060] In some embodiments, please refer to Figure 3The second hood 2 is provided with a buckle part 2d, and the first hood 1 is provided with a slot 16, and the buckle part 2d is buckled in the slot 16.

[0061] For example, please refer to Figure 3 A slot 16 is provided on the first top plate 1a, and the slot 16 is in the shape of a rectangular notch; a buckle 2d is provided on the third side plate 2b, and the buckle 2d includes a first plate segment 2d1 and a second plate segment 2d2. The first plate segment 2d1 connects the third side plate 2b and the second plate segment 2d2, and the first plate segment 2d1 is used to snap into the slot 16; the second plate segment 2d2 is spaced apart from the third side plate 2b, and the second plate segment 2d2 protrudes from the first plate segment 2d1 along the first direction X, so as to form a clamping groove between the second plate segment 2d2 and the third side plate 2b, thereby clamping the first top plate 1a, and then snapping the second hood 2 and the first hood 1 together, reducing the number of fasteners, reducing costs, and simplifying the connection steps of the first hood 1 and the second hood 2.

[0062] Secondly, please refer to Figure 4 , Figure 8 and Figure 9 This application provides an energy storage device 200, which includes a housing 210, a first circuit board 220, a second circuit board 230, a third circuit board 240, a first heat dissipation component 250, a second heat dissipation component 260, a third heat dissipation component 270, and a heat dissipation structure 100.

[0063] The outer casing 210 has a first ventilation opening 211 and a second ventilation opening 212 arranged opposite to each other along a first direction X. The first ventilation opening 211 is positioned directly opposite the first air inlet 12, the second air inlet 22, and the second diversion opening 15, while the suction fan 3 is positioned directly opposite the second ventilation opening 212. The first ventilation opening 211 is used to draw gas from the outside of the outer casing 210 through the first air inlet 12, the second air inlet 22, and the second diversion opening 15; the second ventilation opening 212 is used to discharge gas through the first air outlet 13.

[0064] Optionally, the first vent 211 includes multiple mesh openings to allow ventilation while protecting the components inside the housing 210. Optionally, the second vent 212 includes multiple mesh openings to allow ventilation while protecting the components inside the housing 210. Optionally, the housing 210 includes two interlocking half-shells 213 to facilitate the assembly and disassembly of the components inside the housing 210.

[0065] The first shroud 1 is mounted on the first circuit board 220; the first heat-dissipating component 250 is disposed on the first circuit board 220 and housed within the first region 111. The first circuit board 220 and the first shroud 1 together form a cylindrical shape with openings at both ends, thereby forming a first air cavity 11, a first air inlet 12, and a first air outlet 13 to dissipate heat from the first circuit board substrate and the first heat-dissipating component 250. Optionally, a sealing plate 4 is disposed on the side of the first circuit board 220 away from the first shroud 1.

[0066] The second circuit board 230 is disposed opposite to the first circuit board 220 in the first direction X and is disposed within the second shroud 2; the third heat-dissipating component 270 is disposed on the second circuit board 230 and housed within the second shroud 2. The first shroud 1 and the second shroud 2 enclose a second air inlet 22 and a second air cavity 21. Both the second circuit board 230 and the third heat-dissipating component 270 are disposed within the second air cavity 21 to dissipate heat from the second circuit board 230 and the third heat-dissipating component 270.

[0067] The third circuit board 240 is disposed on the same side of the first circuit board 220 and the second circuit board 230; the second heat sink 260 is disposed on the side of the third circuit board 240 facing the first fan shroud 1. The third circuit board 240 is disposed opposite to the second turning port 15, and the second heat sink 260 is disposed on the side of the third circuit board 240 facing the second turning port 15. When the second turning port 15 draws in gas, an airflow is formed on the third circuit board 240 near the second turning port 15 to dissipate heat from the third circuit board 240 and the second heat sink 260.

[0068] The heat generated by the second heat-dissipating component 260 and the third heat-dissipating component 270 is less than that of the first heat-dissipating component 250. Based on the above, the first heat dissipation airflow channel has a better heat dissipation effect than the second heat dissipation airflow channel, thus allowing for targeted heat dissipation of different heat-dissipating components according to their heat generation characteristics, resulting in more consistent temperatures and improving the problem of uneven heat dissipation across different components.

[0069] The first circuit board 220 and the third circuit board 240 can be mounted on the housing 210, and the second circuit board 230 can be mounted on either the housing 210 or the first circuit board 220. The second shroud 2 can be partially connected to the second circuit board 230, and the other part can be connected to the first shroud 1 via a snap-fit ​​part 2d. Optionally, the second circuit board and the third circuit board 240 are electrically connected, and the connection point between the second circuit board and the third circuit board 240 is exposed at the second turning port 15 to dissipate heat at the electrical connection point between the second circuit board and the third circuit board 240.

[0070] In some embodiments, please refer to Figure 4 and Figure 5 The first heat-dissipating component 250 includes multiple first heating elements 251, a first heat sink 252, and a second heat sink 253, all disposed on the first circuit board 220. Both the first heat sink 252 and the second heat sink 253 conduct heat to the first heating elements 251. The heat conduction of heat to the first heating elements 251 through the first heat sink 252 and the second heat sink 253 enhances the heat dissipation effect on the first heating elements 251. Optionally, the first heat sink 252 and the second heat sink 253 are finned heat sinks, increasing the heat dissipation area within the first region 111 to enhance the heat dissipation effect on the first heating elements 251. Optionally, the first heating element 251 is a transformer, located between the first heat sink 252 and the second heat sink 253.

[0071] In some embodiments, please refer to Figure 4 and Figure 5 The third heat-dissipating component 270 includes multiple second heating elements 271, all disposed on the second circuit board 230, and a third heat sink 272, which conducts heat to the second heating elements 271. The heat dissipation effect on the second heating elements 271 is enhanced by the heat conduction through the third heat sink 272. Optionally, the third heat sink 272 is a finned heat sink, which increases the heat dissipation area within the second air cavity 21 to enhance the heat dissipation effect on the second heating elements 271. The heat generated by the multiple second heating elements 271 is less than that of the multiple first heating elements 251, meaning the heat generated by the second heat-dissipating component 260 is less than that of the first heat-dissipating component 250.

[0072] In some embodiments, please refer to Figure 4 , Figure 5 and Figure 8 The second heat-dissipating component 260 includes a panel 261 and a third heat-generating element 262 located on the panel 261. The panel 261 extends from the first vent 211 toward the second vent 212 in a first direction X. The heat dissipation structure 100 can dissipate heat from the panel 261 and the third heat-generating element 262 on the panel 261, for example, to dissipate heat from the touch screen, plug-in ports, buttons, etc. on the panel 261, thereby improving the user experience. The heat generated by the third heat-generating element 262 is less than that of the plurality of first heat-generating elements 251, that is, the heat generated by the second heat-dissipating component 260 is less than that of the first heat-dissipating component 250.

[0073] In some embodiments, please refer to Figure 5The energy storage device 200 also includes a plurality of fourth heating elements 280, which are arranged in a row along the first direction X and facing the second region 112. A suction fan 3 is used to draw external airflow into the housing 210 from the first vent 211, carrying the heat from the fourth heating elements 280 into the second region 112. Exemplarily, the fourth heating elements 280 are located on the side of the second turning port 15 away from the first direction X, so that when the second turning port 15 draws in gas, an airflow is formed at the fourth heating elements 280 to dissipate heat. It is understood that the total heat generation of the plurality of fourth heating elements 280 and the third heating element 262 is less than the heat generation of the plurality of first heating elements 251. Optionally, the fourth heating elements 280 are disposed on the first circuit board 220. Optionally, the fourth heating elements 280 are capacitors.
