Description

Technical Field

[0001] This utility model relates to heat dissipation technology for energy storage devices, and in particular to a heat dissipation device and an energy storage device. Background Technology

[0002] Energy storage cabinets are devices used to store electrical energy. They convert electrical energy into chemical energy and store it for later use. They are widely used in the fields of renewable energy and electric vehicles, helping to improve energy efficiency and smooth grid load.

[0003] Energy storage cabinets effectively dissipate accumulated heat by connecting the cooling ducts and vents. However, this design also presents a problem: external dust can easily enter the cabinet through the vents and cooling ducts. Although dust filters are widely used to mitigate dust intrusion, their ability to block extremely fine dust particles is still insufficient. These tiny particles can still penetrate the dust filters and enter the cabinet. Even when the internal temperature of the energy storage cabinet is low or it is not in operation and does not require cooling, dust can still enter the cabinet through the vents. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation device and an energy storage device to overcome the shortcomings of the prior art, which can ensure efficient heat dissipation of the energy storage device and reduce dust entering the energy storage device, thus ensuring the good operation of the energy storage device.

[0005] To achieve one of the above objectives, this utility model provides a heat dissipation device, comprising:

[0006] The housing has a heat dissipation duct inside. The housing includes an outer shell and a cover plate. The outer shell has a side plate that is disposed opposite to the cover plate. An air inlet is disposed on the side plate, and an air outlet is disposed on the cover plate.

[0007] A bracket is disposed inside the housing and is located at the lower part of the exhaust port;

[0008] The blade is rotatably disposed within the housing and can be opened to close the air inlet. When the blade is in the open state, the side edge of the blade faces the bracket.

[0009] As a further improvement of one embodiment of the present invention, the bracket includes a connecting plate connected to the cover plate and a baffle connected to the connecting plate. The baffle is inclined to the connecting plate, and when the blade is in the open state, the blade and the baffle have the same inclination angle.

[0010] As a further improvement of one embodiment of the present utility model, a plurality of mounting brackets are provided inside the housing, and a plurality of brackets are provided. The plurality of mounting brackets and the brackets are arranged alternately at intervals. The mounting bracket includes a base plate connected to the cover plate and an extension plate connected to the base plate. The side edge of the extension plate is attached to the side plate.

[0011] As a further improvement of one embodiment of the present invention, a dust collection groove is provided inside the mounting frame, and the upper edge of the dust collection groove is flush with the lower edge of the exhaust port.

[0012] As a further improvement of one embodiment of the present invention, a dustproof net matching the exhaust port is connected to the cover plate.

[0013] As a further improvement of one embodiment of the present invention, a plurality of blades are provided, and a rotating shaft is connected to each blade. The blades are rotatably disposed in the housing via the rotating shaft, and all the blades are connected to a connecting rod to achieve synchronous rotation.

[0014] As a further improvement of one embodiment of the present utility model, a plurality of rotating wheels are rotatably arranged inside the side plate, the rotating shaft is fixedly connected to the axis of the rotating wheels, and the connecting rod is rotatably connected to the eccentric position of all the rotating wheels.

[0015] The housing is provided with a driving component that drives the rotating wheel to rotate synchronously. The driving component includes a servo motor disposed in the housing, a driving wheel connected to the output shaft of the servo motor, and a driven wheel that is drivenly connected to the driving wheel. The connecting rod is rotatably connected to the eccentric position of the driven wheel.

[0016] As a further improvement of one embodiment of the present invention, a buffer pad is provided on the side of the blade facing the side plate.

[0017] As a further improvement of one embodiment of the present invention, a mounting ear plate is connected inside the housing, and the cover plate is detachably fixed to the mounting ear plate.

[0018] To achieve one of the above objectives, one embodiment of the present invention provides an energy storage device, including the above-mentioned heat dissipation device, wherein the heat dissipation device is detachably fixed to the energy storage device, and the energy storage device is provided with a heat dissipation port corresponding to the air inlet.

[0019] Compared to existing technologies, the blades in this invention close the air inlet when vertical, blocking external air and dust from inside the casing. When the blades rotate and tilt, the air inlet opens, allowing heat from the energy storage device to enter the casing and then exit through the exhaust vent, thus dissipating heat from the energy storage device. Since the blades tilt and open towards the support frame, they guide airflow to the upper part of the support frame, blowing accumulated dust onto the exhaust vent, reducing dust inside the casing and minimizing dust entry into the energy storage device. Therefore, the heat dissipation device in this invention ensures both efficient heat dissipation for the energy storage device and reduces dust entry, guaranteeing its proper operation.

[0029] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The terms used in this embodiment, such as "upper," "above," "lower," and "below," which indicate spatial relative positions, are used for ease of explanation to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms "spatial relative position" may be intended to include different orientations of the device besides those shown in the figures during use or operation. For example, in this embodiment, "upper," "lower," "left," "right," "horizontal," and "vertical" all refer to the spatial relative position of the energy storage device under normal operating conditions.

[0031] Furthermore, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, a connection can be a direct connection or an indirect connection through an intermediate medium; it can be a fixed connection, a movable connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the appendices in the embodiments of this utility model will be described below. Figure 1 -7. The technical solutions in the embodiments of this utility model are clearly and completely described.

[0033] One embodiment of this utility model provides a heat dissipation device for cooling an energy storage device. Of course, the heat dissipation device provided by this utility model can also be used to cool other devices that require cooling. The heat dissipation device includes a housing 10, and a heat dissipation duct 15 is formed inside the housing 10. The housing 10 can be independent of the aforementioned energy storage device and other devices requiring cooling; when cooling is needed, the housing 10 can be installed on the energy storage device.

[0034] The housing 10 includes an outer shell 11 and a cover plate 12, which are interconnected to define a chamber. The heat dissipation duct 15 is located within this chamber. The outer shell 11 has a side plate 13 disposed opposite to the cover plate 12, i.e., the side plate 13 and the cover plate 12 are parallel to each other. An air inlet 131 is provided on the side plate 13, and an air outlet 121 is provided on the cover plate 12. Both the air inlet 131 and the air outlet 121 are arranged at intervals along the height direction of the housing 10. In this embodiment, the air inlet 131 and the air outlet 121 are staggered along the arrangement direction. In other embodiments, the air inlet 131 and the air outlet 121 may also be flush. This embodiment does not specifically limit this.

[0035] The heat dissipation device also includes a bracket 20, a mounting bracket 30, and a blade 40 disposed within the housing 10. The bracket 20 and the mounting bracket 30 are correspondingly fixed to one side of the cover plate 12, and both the bracket 20 and the mounting bracket 30 are located below the exhaust port 121. Both the bracket 20 and the mounting bracket can intercept dust entering the housing 10 through the exhaust port 121. The blade 40 is correspondingly disposed on one side of the side plate 13, and the blade 40 can be opened and closed at the air inlet 131. When the blade 40 is in the open state, the side edge of the blade 40 is positioned facing the bracket 20.

[0036] When the blade 40 is in the vertical position, the air inlet 131 is closed, which can block external air and dust inside the casing 10. When the blade 40 is rotated and tilted, the air inlet 131 is opened, and the heat in the energy storage device enters the casing 10 through the air inlet 131 and is then discharged through the exhaust port 121, which can dissipate heat from the energy storage device. Since the blade 40 faces the support 20 when it is tilted and opened, the blade 40 guides the airflow to the upper end of the support 20, which can blow the dust accumulated on the support 20 toward the exhaust port 121, reducing the amount of dust inside the casing 10 and thus minimizing the entry of dust into the energy storage device.

[0037] The blade 40 is provided with several blades that match the air inlet 131. A rotating shaft 41 is connected to the blade 40, and the blade 40 is rotatably mounted inside the housing 10 via the rotating shaft 41. More specifically, two parallel mounting plates 14 are fixedly installed inside the housing 10. The blade 40 is positioned between the two mounting plates 14. A rotating wheel 42 is provided on each of the opposite sides of the two mounting plates 14. Connecting lugs 43 are connected to both ends of the blade 40. One end of the rotating shaft 41 is fixedly connected to the connecting lug 43, and the other end of the rotating shaft 41 passes through the mounting plate 14 and is fixedly connected to the rotating wheel 42. That is, the rotating shaft 41 is fixedly connected to the axis of the rotating wheel 42.

[0038] In this embodiment, all blades 40 can rotate synchronously. To achieve this, a drive unit 50 is provided inside the housing 10 to drive the rotating wheels 42 to rotate synchronously. The drive unit 50 includes a servo motor 51 disposed inside the housing 10, a drive wheel 52 connected to the output shaft of the servo motor 51, and a driven wheel 53 driven by the drive wheel 52. A belt 54 drives the drive wheel 52 and the driven wheel 53. In an optional embodiment, the drive wheel 52 and the driven wheel 53 can also be configured as gears or sprockets, as long as the rotation of the drive wheel 52 drives the driven wheel 53 to rotate synchronously.

[0039] All blades 40 are connected to a connecting rod 44. For example, the connecting rod 44 is rotatably connected to the eccentric position of all rotating wheels 42 and to the eccentric position of driven wheel 53. The eccentric position is offset from the axis of the rotating wheel 42 and driven wheel 53 by the same offset distance and offset angle.

[0040] Start the servo motor 51, which drives the drive wheel 52 to rotate. The drive wheel 52 drives the driven wheel 53 to rotate via the belt 54. The rotation of the driven wheel 53 drives the connecting rod 44 to deflect. As a result, the connecting rod 44 drives all the rotating wheels 42 to rotate, thereby realizing the synchronous rotation and flipping of all the blades 40. That is, all the blades 40 can open and close synchronously.

[0041] The servo motor 51 is located between the two mounting plates 14. The output shaft of the servo motor 51 passes through the mounting plate 14 and is connected to the drive wheel 52, which makes the mounting structure of the drive component 50 more compact and also facilitates the assembly of the drive component 50.

[0042] To ensure a tighter fit between the blade 40 and the air inlet 131 while preventing the side plate 13 from interfering with the rotation of the blade 40, a buffer pad 45 is provided on the outer side of the blade 40. More specifically, when the blade 40 is in the tilted open state, a buffer pad 45 is connected to the bottom of the blade 40. The buffer pad 45 is made of a deformable elastic material, which can prevent interference between the blade 40 and the air inlet 131 during rotation. A buffer pad 45 can also be provided on the upper side of the blade 40 when it is in the open state.

[0043] As a further limitation, the number of brackets 20 corresponds to the number of blades 40 and air inlets 131. Accordingly, a heat dissipation duct 15 is formed between the air inlets 131 and the exhaust vent 121 adjacent to the air inlet 131. The bracket 20 includes a connecting plate 21 connected to the cover plate 12 and a baffle 22 connected to the connecting plate 21. The baffle 22 is inclined to the connecting plate 21 and gradually tilts towards one side of the side plate 13 from bottom to top. When dust enters from the exhaust vent 121, most of the dust will first hit the baffle 22 due to the limiting effect of the baffle 22. Therefore, the baffle 22 can intercept the dust. When the blades 40 are in the open state, the blades 40 and the baffle 22 have the same tilt angle, and the side edge of the blades 40 is adjacent to the side edge of the baffle 22. The airflow entering the housing 10 from the air inlet 131 will be guided by the blade 40 and flow to the baffle 22 above the bracket 20, so that the dust accumulated above the bracket 20 can be discharged from the exhaust port 121.

[0044] There are several mounting brackets 30, which are arranged alternately with the bracket 20. The mounting brackets 30 are also located below the exhaust port 121. In this embodiment, the number of exhaust ports 121 is about twice the number of air inlets 131. This arrangement can improve the ventilation and heat dissipation performance of the heat dissipation device and reduce the possibility of dust entering the energy storage device from the air inlet 131.

[0045] The mounting bracket 30 includes a base plate 31 connected to the cover plate 12 and an extension plate 32 connected to the base plate 31. The side edge of the extension plate 32 is attached to the side plate 13. The extension plate 32 is parallel to the baffle 22. The base plate 31 is located below the exhaust port 121. Therefore, one side of the extension plate 32 is located below the exhaust port 121, and the other side is attached to the side plate 13. The extension plate 32 can separate adjacent heat dissipation air ducts 15, thus blocking dust. A dust collection groove 33 is provided inside the mounting bracket 30. The upper edge of the dust collection groove 33 is flush with the lower edge of the exhaust port 121. Dust entering the housing 10 through the exhaust port 121 can be collected in the dust collection groove 33 for easy cleaning. A dustproof net 122 matching the exhaust port 121 is connected to the cover plate 12. The dustproof net 122 can reduce the amount of dust entering the housing 10 through the exhaust port 121.

[0046] As a further limitation, the cover plate 12 is detachably connected to the housing 10. The housing 10 is connected to a mounting ear plate 16, which is located at the corner formed by the two mounting plates 14 and the housing 10. Both the mounting ear plate 16 and the cover plate 12 are provided with connection holes, and the cover plate 12 can be fixed to the housing 10 by screws or bolts. When it is necessary to clean the inside of the housing 10, the cover plate 12 can be removed relatively easily.

[0047] To facilitate the installation of the heat dissipation device, mounting grooves 17 are provided at the four corners of the housing 10. The housing 10 forms mounting lugs 18 at the corners that match the mounting grooves 17. The mounting lugs 18 are provided with connecting holes, and the heat dissipation device can be fixed by screws or bolts.

[0048] One embodiment of this utility model provides an energy storage device, including an energy storage cabinet 60. Several shelves 61 are fixedly arranged inside the energy storage cabinet 60. The energy storage structure and other components can be installed on the shelves 61. A door 62 is pivotally connected to the front side of the energy storage cabinet 60. The door 62 can be opened and closed at the opening on the front side of the energy storage cabinet 60 to facilitate subsequent maintenance by the staff.

[0049] The rear side of the energy storage cabinet 60, opposite the door 62, is designated as a rear panel. This rear panel has several heat dissipation vents (not shown in the figure) corresponding to the air inlets 131 in the aforementioned heat dissipation device. The heat dissipation device is detachably fixed to the rear side of the energy storage cabinet 60. The rear panel of the energy storage cabinet 60 may have connection holes corresponding to the mounting lugs 18, facilitating the installation and assembly of the heat dissipation device. After installation, the heat dissipation vents correspond one-to-one with the air inlets 131. A cooling fan may be installed inside the energy storage cabinet 60, which can transfer the heat generated by the energy storage device during operation from the heat dissipation vents to the air inlets 131, thus achieving heat dissipation for the energy storage device.

[0050] Since the heat dissipation device is independent of the energy storage device, and there is a buffer space inside the heat dissipation device for dust to enter, the dust can enter the heat dissipation device first and be collected in the heat dissipation device, which can reduce the possibility of dust entering the energy storage device and ensure the proper operation of the energy storage device.

[0051] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
