Description

Technical Field

[0001] The present application relates to the technical field of heat exchangers, and particularly to a heat exchange structure and an energy storage device. Background Art

[0002] With the continuous development of photovoltaic power generation technology, heat exchangers are widely used in photovoltaic inverters, energy storage inverters, etc., and are used in desert and gobi environments. Since there is a lot of dust in the desert and gobi environments and the dust will float around under the drive of wind, when the heat exchanger exchanges heat with the outside cold air, the dust in the outside environment is likely to enter the interior of the heat exchanger along with the air, causing damage or blockage to the heat exchange components inside the heat exchanger. The existing dust removal solutions require the heat exchanger to be disassembled for dust removal, which not only consumes a large amount of labor costs and reduces the dust removal efficiency, but also easily affects the airtightness and structural reliability of the heat exchanger during the repeated disassembly and assembly process.

[0003] Therefore, there is an urgent need for a heat exchange structure and an energy storage device to solve the above problems. Summary of the Utility Model

[0051] Embodiment 1

[0052] With the continuous development of photovoltaic power generation technology, heat exchangers are widely used in photovoltaic inverters, energy storage inverters, etc., and are used in the environments of deserts and gobi. Since there is a lot of dust in the desert and gobi environments and the dust will float around under the drive of wind, when the heat exchanger exchanges heat with the outside cold air, the dust in the external environment is likely to enter the interior of the heat exchanger along with the air, causing damage or blockage to the heat exchange components inside the heat exchanger. The existing sand removal solutions require the heat exchanger to be disassembled for sand removal, which not only consumes a large amount of labor costs and reduces the sand removal efficiency, but also easily affects the airtightness and structural reliability of the heat exchanger during the process of repeatedly disassembling and assembling the heat exchanger.

[0053] To solve the above problems, as Figure 1 and Figure 2As shown in the figure, this embodiment provides a heat exchange structure, which includes a support housing 300, a heat exchange element 100, and a fan 200. Among them, the support housing 300 has a receiving cavity 310 and an air inlet 321 communicating with the receiving cavity 310. The support housing 300 includes a first surface 320 and a second surface 330. The first surface 320 is located above the second surface 330. A sand removal port 331 communicating with the receiving cavity 310 is provided on the second surface 330. The heat exchange element 100 is disposed in the receiving cavity 310. The fan 200 communicating with the receiving cavity 310 is provided on the first surface 320. The heat exchange element 100 has a heat exchange surface 110, and the heat exchange surface 110 faces the air inlet 321. The air inlet 321, the heat exchange element 100, and the fan 200 form a first air duct; the fan 200, the heat exchange element 100, and the sand removal port 331 form a second air duct, or the fan 200 and the sand removal port 331 form a third air duct. The heat exchange structure provided by this embodiment enables the cold air in the external environment to enter the receiving cavity 310 through the air inlet 321 to exchange heat with the heat exchange element 100 under the action of the fan 200, and then be discharged through the fan 200, thereby realizing ventilation and heat exchange of the heat exchange element 100 through the first air duct. In addition, the fan 200, the heat exchange element 100, and the sand removal port 331 form a second air duct, or the fan 200 and the sand removal port 331 form a third air duct, so that the dust entering the receiving cavity 310 can be automatically discharged through the second air duct or the third air duct, achieving the effect of automatic dust removal. There is no need to remove the heat exchange element 100 additionally for sand removal, which improves the sand removal efficiency and also improves the protection of the heat exchange element 100.

[0054] ]>Optionally, in this embodiment, as Figure 1 shown by the dotted arrow in the figure, when the fan 200 is turned on and the fan 200 performs the air extraction operation, the cold air in the external environment can flow along the first air duct, thereby realizing ventilation and heat exchange of the heat exchange element 100 through the first air duct. Optionally, in this embodiment, as Figure 2 shown by the solid arrow in the figure, the fan 200 and the sand removal port 331 form a third air duct. When the fan 200 is turned on and the fan 200 performs the air blowing operation, the air blown into the receiving cavity 310 by the fan 200 can discharge the dust accumulated in the receiving cavity 310 through the sand removal port 331, thereby achieving the effect of automatic dust removal. It should be noted that when the fan 200 is turned on and the fan 200 performs the air blowing operation, the dust in the receiving cavity 310 at this time will not pass through the heat exchange element 100 and can be directly discharged through the sand removal port 331, further improving the protection effect on the heat exchange element 100.

[0055] Optionally, in this embodiment, the heat exchange element 100 can be a microchannel heat exchanger, which has good heat exchange effect and high heat exchange efficiency. The heat exchange element 100 can also be a heat pipe, a fin, or other heat exchange structures. This embodiment does not make specific limitations on the specific form of the heat exchange element 100.

[0056] Optionally, in this embodiment, two heat exchange elements 100 are arranged at intervals in the accommodation cavity 310. The two heat exchange elements 100 are both arranged obliquely. An air inlet 321 corresponds to the heat exchange surface 110 of each heat exchange element 100, which increases the ventilation and heat exchange area of the heat exchange element 100, and thus improves the heat exchange effect of the entire heat exchange structure. Optionally, in this embodiment, the two heat exchange elements 100 are arranged in a "V" shape, and the fan 200 is located in the middle of the two heat exchange elements 100, so as to ensure that the heat exchange effects of the two heat exchange elements 100 are the same. In other embodiments, the specific number and arrangement of the heat exchange elements 100 can be adjusted according to requirements.

[0057] Optionally, in this embodiment, a plurality of fans 200 are arranged at intervals on the first surface 320. The plurality of fans 200 work synchronously, effectively improving the ventilation and heat exchange efficiency of the heat exchange element 100 and the dust removal effect inside the accommodation cavity 310. The specific number of the fans 200 in this embodiment is not limited. In other embodiments, only one fan 200 can also be arranged on the first surface 320.

[0058] Optionally, in this embodiment, the first surface 320 is the upper end surface of the support housing 300, and the second surface 330 is the side surface of the support housing 300. In other embodiments, the second surface 330 can also be the lower end surface of the support housing 300.

[0059] Optionally, in this embodiment, as Figure 1 and Figure 2 shown, an air inlet 321 is arranged on the first surface 320. In other embodiments, the air inlet 321 can also be arranged on the second surface 330, so that the air inlet 321 coincides with the sand removal port 331, that is, the sand removal port 331 and the air inlet 321 share one opening, and this opening is opened on the second surface 330 (i.e., the side surface of the support housing 300). When the fan 200 performs the air extraction work, the opening opened on the second surface 330 serves as the air inlet 321. When the fan 200 performs the air blowing work, the opening opened on the second surface 330 serves as the sand removal port 331, making the structure simple and more convenient for processing and manufacturing.

[0060] Optionally, in this embodiment, as Figure 1 and Figure 2As shown, the heat exchange structure further includes a guide member 500. The guide member 500 is connected to the support housing 300. The first end 530 of the guide member 500 extends towards the sand removal port 331, and the second end 540 of the guide member 500 extends towards the fan 200. Moreover, the straight-line distance between the first end 530 and the first surface 320 is greater than the straight-line distance between the second end 540 and the first surface 320. With the above arrangement, the guide member 500 slopes upward from the first end 530 to the second end 540, enabling the guide member 500 not only to guide the hot air after heat exchange with the heat exchange member 100 to be quickly discharged through the fan 200, but also to guide the accumulated dust in the accommodation cavity 310 to be discharged through the sand removal port 331.

[0061] Optionally, in this embodiment, as Figure 1 and Figure 2 shown, the guide member 500 is rotatably connected to the support housing 300. The guide member 500 has a first position and a second position. The guide member 500 has opposite first side surface 510 and second side surface 520. As Figure 1 shown, when the guide member 500 is in the first position, the first side surface 510 conducts the heat exchange member 100 and the fan 200, enabling the hot air after heat exchange with the heat exchange member 100 to enter the fan 200 along the first side surface 510 and be discharged through the fan 200. As Figure 2 shown, when the guide member 500 is in the second position, the second side surface 520 conducts the fan 200 and the sand removal port 331, enabling the accumulated dust in the accommodation cavity 310 to flow towards the sand removal port 331 along the second side surface 520 and finally be discharged through the sand removal port 331. It should be noted that, in this embodiment, both the first side surface 510 and the second side surface 520 are inclined planes, and the sand removal port 331 is located below the side surface of the support housing 300. Since hot air currents tend to flow upward, the hot air after heat exchange with the heat exchange member 100 easily moves upward along the first side surface 510 to the fan 200. In addition, since dust tends to sink under the action of its own gravity, the accumulated dust in the accommodation cavity 310 is more likely to flow downward along the second side surface 520 to the sand removal port 331. In addition, it should be noted that when the guide member 500 is in the second position for dust removal operation, the second side surface 520 of the guide member 500 can prevent the dust from being blown onto the heat exchange member 100, further improving the protection effect on the heat exchange member 100.

[0062] Optionally, in this embodiment, as Figure 1 and Figure 2 shown, the heat exchange structure further includes a limiting member 600. The limiting member 600 is arranged on the inner wall of the support housing 300 and is adjacent to the first end 530 of the guide member 500. As Figure 1 shown, when the guide member 500 is in the first position, the first end 530 is in close contact with the limiting member 600 to position the guide member 500 in the first position. AsFigure 2 As shown, when the guide member 500 is in the second position, the first end 530 disengages from the limiting member 600. Optionally, in this embodiment, the limiting member 600 is disposed on the inner bottom wall of the support housing 300, and the limiting member 600 can be designed in the form of an electromagnetic absorber. After the limiting member 600 is powered on, the limiting member 600 can magnetically fix the first end 530.

[0063] Optionally, in this embodiment, the guide member 500 is rotatably connected to the cavity wall of the accommodation cavity 310 through a pivot shaft 550, and a torsion spring is disposed on the pivot shaft 550. When ventilation and heat exchange are required for the heat exchange member 100 in the accommodation cavity 310, at this time, the fan 200 performs an air extraction operation, and the limiting member 600 is powered on, so that the limiting member 600 magnetically fixes the first end 530. When it is necessary to remove the dust accumulated in the accommodation cavity 310, at this time, the fan 200 performs a blowing operation, and the limiting member 600 is powered off, so that the guide member 500 is reset to the second position under the elastic action of the torsion spring, and the first end 530 disengages from the limiting member 600.

[0064] Optionally, in this embodiment, the guide member 500 is in the form of an inclined guide plate. Optionally, in this embodiment, two guide members 500 are spaced apart in the accommodation cavity 310, and the two guide members 500 are arranged in a "V" shape in the accommodation cavity 310. A dust removal port 331 corresponds to each first end 530 of the guide members 500, and the fan 200 is located in the middle of the two guide members 500. The two guide members 500 are spaced apart, so as to ensure that the air blown into the accommodation cavity 310 enters the second side surface 520 below the guide member 500. By providing two guide members 500, the heat exchange effect and dust removal effect of the heat exchange structure are effectively improved.

[0065] This embodiment also provides an energy storage device. The energy storage device provided in this embodiment includes a cabinet, a power device, and the above heat exchange structure. The power device is accommodated in the cabinet, and the heat exchange structure is fixed outside the cabinet. The heat exchange structure is used to dissipate heat from the power device. The energy storage device provided in this embodiment, by applying the above heat exchange structure, enables the dust entering the accommodation cavity 310 to be automatically discharged through the third air duct, achieving the effect of automatic dust removal, without the need to remove the heat exchange member 100 additionally for dust removal, improving the dust removal efficiency, and also improving the protection of the energy storage device.

[0066] Embodiment Two

[0067] The heat exchange structure provided in this embodiment is basically the same as that in Embodiment One. The difference between the heat exchange structure provided in this embodiment and that in Embodiment One is as follows:

[0068] In this embodiment, as Figures 3 to 7As shown, the heat exchange structure further includes a dust collection box 400. The dust collection box 400 is detachably connected to the support housing 300 and is in communication with the sand removal port 331. By providing the dust collection box 400 in communication with the sand removal port 331, the dust discharged from the sand removal port 331 can be collected by the dust collection box 400, preventing the dust discharged from the sand removal port 331 from spreading to other equipment. It should be noted that when the dust collection box 400 is full of dust, the dust collection box 400 can be removed from the support housing 300 for centralized cleaning.

[0069] In this embodiment, as Figure 4 and Figure 6 shown by the dotted arrows in Figure 5 and Figure 7 , when the fan 200 is turned on and the fan 200 performs the air extraction operation, the cold air in the external environment can flow along the first air duct. After the cold air in the external environment enters the accommodation cavity 310 through the air inlet 321 and exchanges heat with the heat exchange member 100, it flows along the heat exchange member 100 and the guiding member 500 in sequence and is finally discharged through the fan 200, thereby realizing ventilation and heat exchange of the heat exchange member 100 through the first air duct. In this embodiment, as

[0070] shown by the solid arrows in

[0071] , the fan 200 and the sand removal port 331 form a third air duct. When the fan 200 is turned on and the fan 200 performs the air blowing operation, the air blown into the accommodation cavity 310 by the fan 200 can discharge the dust accumulated in the accommodation cavity 310 through the sand removal port 331 into the dust collection box 400, thereby achieving the effect of automatic dust removal.

[0072] Optionally, in this embodiment, the dust collection box 400 and the guiding member 500 can be designed as an integrally formed part, such that the first end 530 of the guiding member 500 is connected to the dust collection box 400, or the dust collection box 400 and the guiding member 500 can be designed as two separate parts, and the first end 530 of the guiding member 500 is fixedly connected to the bottom wall of the accommodation cavity 310.

[0073] Optionally, in this embodiment, the dust collection box 400 can be integrally bent and formed from a sheet metal part. By processing the dust collection box 400 through sheet metal bending, not only the processing efficiency of the dust collection box 400 is improved, but also the processing cost and difficulty of the dust collection box 400 are reduced. The dust collection box 400 can also be processed by casting or other processing methods, and this embodiment does not make specific limitations.

[0074] In addition, in this embodiment, each dust removal port 331 is connected to a dust collection box 400, thereby ensuring the dust collection effect. Optionally, in this embodiment, the two dust collection boxes 400 can be two separate parts, or the two dust collection boxes 400 can be an integrally formed part. The two dust collection boxes 400 are bent and formed from a sheet metal part to further improve the processing efficiency and installation efficiency.

[0075] Optionally, in this embodiment, as Figures 3 to 5 shown, the cavity wall of the collection cavity 410 of the dust collection box 400 can be designed as a rectangle. Optionally, in this embodiment, as Figure 6 and Figure 7 shown, the inner cavity wall of the dust collection box 400 can also be arc-shaped, which is more conducive to uniformly collecting dust at the bottom of the dust collection box 400.

[0076] Optionally, in this embodiment, the second surface 330 is the lower end surface of the support housing 300, and the first surface 320 and the second surface 330 are opposite in the up and down direction, thereby ensuring that the dust flows along the guide member 500 to the dust removal port 331 under the action of its own gravity and is discharged into the dust collection box 400 through the dust removal port 331 at the bottom.

[0077] Optionally, in this embodiment, as Figures 3 to 7 shown, an air inlet 321 is provided on the first surface 320.

[0078] Optionally, in this embodiment, two guide members 500 are spaced apart in the accommodation cavity 310. The two guide members 500 are arranged in a "V" shape in the accommodation cavity 310, and the second ends 540 of the two guide members 500 are connected. Optionally, the two guide members 500 can be an integrally formed part, which not only ensures the structural strength of the two guide members 500, but also ensures the stability and reliability of the guide members 500 in the accommodation cavity 310.

[0079] Optionally, in this embodiment, as Figures 3 to 5 shown, the guide member 500 can be in the form of an inclined guide plate. Optionally, in this embodiment, as Figure 6 and Figure 7As shown, the guiding member 500 can also be in the form of an arc-shaped guiding plate, as long as it can ensure that the guiding member 500 guides the dust towards the sand removal opening 331 and guides the heated air after heat exchange towards the blower 200. It should be noted that by designing the guiding member 500 in the form of an arc-shaped guiding plate, the resistance of the guiding member 500 during air guiding and sand guiding is further reduced.

[0080] This embodiment also provides an energy storage device. The energy storage device provided in this embodiment includes a cabinet, power devices, and the above heat exchange structure. The power devices are accommodated in the cabinet, and the heat exchange structure is fixed outside the cabinet. The heat exchange structure is used to dissipate heat from the power devices. The energy storage device provided in this embodiment, by applying the above heat exchange structure, enables the dust entering the accommodation cavity 310 to be automatically discharged through the second air duct, achieving the effect of automatic dust removal. There is no need to additionally remove the heat exchange member 100 for sand removal, which improves the sand removal efficiency and also improves the protection of the energy storage device.

[0081] Embodiment Three

[0082] The heat exchange structure provided in this embodiment is basically the same as that in Embodiment Two. The difference between the heat exchange structure provided in this embodiment and that in Embodiment Two is as follows:

[0083] In this embodiment, as Figures 8 to 10 shown, the dust collection box 400 is provided with an open mouth 411 communicating with the sand removal opening 331. A guiding member 420 is provided on the side wall of the open mouth 411, and the guiding member 420 extends towards the collection cavity 410 of the dust collection box 400. By providing the guiding member 420, as Figure 9 shown by the solid arrow in, the blower 200 and the sand removal opening 331 form a third air duct. When the blower 200 is turned on and the blower 200 blows air, the air blown into the accommodation cavity 310 by the blower 200 can flow the accumulated dust in the accommodation cavity 310 along the guiding member 500 to the sand removal opening 331 for discharge. The dust discharged from the sand removal opening 331 flows downward along the guiding member 420 to the bottom of the collection cavity 410 of the dust collection box 400, providing guidance for the collection of dust, thereby better collecting the dust discharged from the sand removal opening 331. In addition, by providing the guiding member 420, the dust flowing into the dust collection box 400 can be prevented from flowing towards the open mouth 411 under the blockage of the guiding member 420. Optionally, in this embodiment, the guiding member 420 can be in the form of an inclined guide plate.

[0084] Optionally, in this embodiment, guiding members 420 are provided on two opposite side walls of the open mouth 411, and the two guiding members 420 jointly guide the dust to flow downward along the guiding member 420 to the bottom of the collection cavity 410 of the dust collection box 400, further improving the dust collection effect of the dust collection box 400.

[0085] This embodiment also provides an energy storage device. The energy storage device provided in this embodiment includes a cabinet, power devices, and the above heat exchange structure. The power devices are accommodated in the cabinet, and the heat exchange structure is fixed outside the cabinet. The heat exchange structure is used to dissipate heat from the power devices. The energy storage device provided in this embodiment, by applying the above heat exchange structure, enables the dust entering the accommodation chamber 310 to be automatically discharged through the second air duct, achieving the effect of automatic dust removal. There is no need to additionally remove the heat exchange member 100 for sand removal, improving the sand removal efficiency and also enhancing the protection of the energy storage device.

[0088] In this embodiment, as Figures 11 to 12 shown, in this embodiment, the fan 200, the heat exchange member 100, and the sand removal port 331 form a second air duct. Specifically, as Figure 11 the dotted arrow in shows, when the fan 200 is turned on and the fan 200 performs the air extraction operation, the cold air in the external environment can flow along the first air duct, so that the cold air in the external environment enters the accommodation chamber 310 through the air inlet 321, exchanges heat with the heat exchange member 100, and then flows along the heat exchange member 100 and the guiding member 500 in sequence, and finally is discharged through the fan 200, thereby realizing the ventilation and heat exchange of the heat exchange member 100 through the first air duct. In this embodiment, as Figure 12 the dotted line arrow in shows, the fan 200, the heat exchange member 100, and the sand removal port 331 form a second air duct. When the fan 200 is turned on and the fan 200 performs the air blowing operation, the air blown into the accommodation chamber 310 by the fan 200 can discharge the dust in the accommodation chamber 310 through the heat exchange member 100, flow along the guiding member 500 to the sand removal port 331, thereby realizing the effect of automatic dust removal.

[0089] As Figure 11 and Figure 12 shown, in this embodiment, the guiding member 500 is fixedly connected to the support housing 300. Optionally, in this embodiment, the first end 530 of the guiding member 500 is fixedly connected to the inner bottom wall of the accommodation chamber 310, making the structure of the heat exchange structure simpler.

[0090] Optionally, in this embodiment, as Figure 11 and Figure 12As shown, an air inlet 321 is provided on the second surface 330, such that the air inlet 321 coincides with the sand removal port 331, that is, the sand removal port 331 and the air inlet 321 share a common opening, and this opening is formed on the second surface 330 (i.e., the side surface of the support housing 300). When the fan 200 is in the air extraction operation, the opening formed on the second surface 330 serves as the air inlet 321. When the fan 200 is in the air blowing operation, the opening formed on the second surface 330 serves as the sand removal port 331, making the structure simple and more convenient for processing and manufacturing.

[0091] Optionally, in this embodiment, two heat exchange elements 100 are spaced apart in the accommodation cavity 310. The two heat exchange elements 100 are both arranged obliquely, and the two heat exchange elements 100 are arranged in a "V" shape, and the fan 200 is located in the middle of the two heat exchange elements 100.

[0092] Optionally, in this embodiment, the guiding member 500 is in the form of an inclined guiding plate. Optionally, in this embodiment, two guiding members 500 are spaced apart in the accommodation cavity 310.

Optionally, the two guiding members 500 can be integrally formed, which not only ensures the structural strength of the two guiding members 500, but also ensures the stability and reliability of the connection and fixation of the guiding member 500 in the accommodation cavity 310.

[0093] This embodiment also provides an energy storage device. The energy storage device provided in this embodiment includes a cabinet, power devices, and the above heat exchange structure. The power devices are accommodated in the cabinet, and the heat exchange structure is fixed outside the cabinet. The heat exchange structure is used to dissipate heat from the power devices. The energy storage device provided in this embodiment, by applying the above heat exchange structure, enables the dust entering the accommodation cavity 310 to be automatically discharged through the third air duct, achieving the effect of automatic dust removal, without the need to additionally remove the heat exchange element 100 for sand removal, improving the sand removal efficiency, and also improving the protection of the energy storage device.

[0094] Embodiment Five

[0095] The heat exchange structure provided in this embodiment is basically the same as that in Embodiment One. The difference between the heat exchange structure provided in this embodiment and that in Embodiment One is as follows:

[0096] In this embodiment, as Figure 13 and Figure 14As shown, the guide member 500 of the heat exchange structure is disposed on the inner sidewall of the accommodation chamber 310. The guide member 500 is arc-shaped and is located on one side of the blower 200. By designing the guide member 500 into an arc shape, the air flow vortices generated at the guide member 500 are reduced, thereby avoiding the turbulent dissipation of the air flow at the guide member 500, reducing the kinetic energy loss of the air flow in the accommodation chamber 310, thus playing a role in reducing air resistance, effectively improving the ventilation and heat exchange effect of the heat exchange member 100 in the accommodation chamber 310, and also improving the blowing and dust removal effect in the accommodation chamber 310.

[0097] In this embodiment, the blower 200, the heat exchange member 100, and the sand removal port 331 form a second air duct. As Figure 13 shown by the dotted arrow in the figure, when the blower 200 is turned on and the blower 200 performs the air extraction operation, the cold air in the external environment can flow along the first air duct, so that the cold air in the external environment enters the accommodation chamber 310 through the air inlet 321, exchanges heat with the heat exchange member 100, then flows along the guide member 500, and finally is discharged through the blower 200, thereby realizing the ventilation and heat exchange of the heat exchange member 100 through the first air duct. In this embodiment, as Figure 14 shown by the dotted line arrow in the figure, the blower 200, the heat exchange member 100, and the sand removal port 331 form a second air duct. When the blower 200 is turned on and the blower 200 performs the blowing operation, the air blown into the accommodation chamber 310 by the blower 200 can flow along the guide member 500, and then passes through the heat exchange member 100 to discharge the accumulated dust in the accommodation chamber 310 through the sand removal port 331, thereby realizing the effect of automatic dust removal.

[0098] Optionally, in this embodiment, as ​ and ​ shown, the second surface 330 is provided with an air inlet 321, so that the air inlet 321 coincides with the sand removal port 331, that is, the sand removal port 331 and the air inlet 321 share a common opening, and this opening is opened on the second surface 330 (i.e., the side surface of the support housing 300). When the blower 200 performs the air extraction operation, the opening opened on the second surface 330 serves as the air inlet 321. When the blower 200 performs the blowing operation, the opening opened on the second surface 330 serves as the sand removal port 33, making the structure simple and more convenient for processing and manufacturing.

[0099] Optionally, in this embodiment, the guide member 500 is a part of the inner sidewall of the support housing 300, thereby making the structure of the entire heat exchange structure simpler.

[0100] Optionally, in this embodiment, two heat exchange members 100 are arranged at intervals in the up and down direction in the accommodation chamber 310, and the two heat exchange members 100 are both arranged obliquely, thereby improving the heat exchange effect of the heat exchange structure.

[0101] This embodiment also provides an energy storage device. The energy storage device provided in this embodiment includes a cabinet, power devices, and the above heat exchange structure. The power devices are accommodated in the cabinet, and the heat exchange structure is fixed outside the cabinet. The heat exchange structure is used to dissipate heat from the power devices. In the energy storage device provided in this embodiment, by applying the above heat exchange structure, the dust entering the accommodation chamber 310 can be automatically discharged through the third air duct, achieving the effect of automatic dust removal. There is no need to additionally remove the heat exchange member 100 for sand removal, which improves the sand removal efficiency and also enhances the protection of the energy storage device.
