[0039] To achieve the above object, please refer to Figures 1 to 3 As shown, the present utility model provides a heat dissipation device. The heat dissipation device includes an air conditioner and a diversion structure 1. The air conditioner is provided with a cold air outlet. The diversion structure 1 includes a connected base 11 and a diversion main body 12. The base 11 is connected to the air conditioner. The diversion main body 12 is provided with an air inlet and a plurality of heat dissipation air outlets 1211 communicating with the air inlet. The air inlet communicates with the cold air outlet. The plurality of heat dissipation air outlets 1211 are arranged at intervals along a straight line. From the heat dissipation air outlet 1211 adjacent to the air inlet to the heat dissipation air outlet 1211 far from the air inlet, the cross-sectional area thereof is gradually increased so that the air flow rates of the plurality of heat dissipation air outlets 1211 are kept consistent.

[0040] In this embodiment, the heat dissipation device is applied to an energy storage device, which includes but is not limited to a solid-state battery energy storage cabinet or energy storage system, a lithium battery energy storage cabinet or energy storage system, etc. The energy storage device stores renewable energy such as solar energy and wind energy and discharges it when needed, or stores electricity during the low electricity consumption period and discharges it when needed. The air conditioner is a refrigeration device with a compressor, a condensation structure, and an evaporation structure. At the same time, the air conditioner also includes a fan to blow cold air in by wind force, that is, this application cools and dissipates heat from the energy storage device by air cooling. By setting the heat dissipation device, the battery during the charging and discharging of the energy storage device can be cooled and dissipated, so as to avoid the battery working temperature being too high.

[0041] In this embodiment, the air conditioner is provided with a cold air outlet, that is, cold air with a lower temperature blows into the energy storage device at the cold air outlet of the air conditioner. In the existing energy storage device, the cold air blows directly on the battery unit, making the ambient temperature of the battery unit adjacent to the air conditioner lower and the temperature of the battery unit far from the air conditioner higher, resulting in uneven cooling temperature and uneven heat dissipation of the battery unit as a whole, thus reducing the air cooling efficiency.

[0042] Based on this, this application provides a diversion structure 1, which includes a connected connection base 11 and a diversion main body 12. The connection base 11 is a structural support component of the diversion structure 1. The connection base 11 can be a structure such as a bracket, a mounting frame, or a mounting table. The connection base 11 is connected to the outer shell of the air conditioner so that the entire diversion structure 1 is connected to the air conditioner. The diversion main body 12 is the main component of the diversion structure 1. The diversion main body 12 can be a diversion chamber or diversion channel formed by a housing, or a diversion pipeline formed by a pipe body, etc. The cold air will enter the energy storage device through the diversion chamber or diversion channel to dissipate heat and cool the energy storage device.

[0043] Further, based on the above embodiment of the present invention, the diversion main body 12 is provided with an air inlet and a plurality of heat dissipation air outlets 1211. The plurality of heat dissipation air outlets 1211 are communicated with the air inlet. For example, if the diversion main body 12 is a housing structure, one end of the diversion housing forms the air inlet, and the other end of the diversion main body 12 forms a plurality of heat dissipation air outlets 1211. The plurality of heat dissipation air outlets 1211 are communicated with the air inlet through the diversion chamber. Or, if the diversion main body 12 is a pipe body structure, one end of the diversion pipe body forms the air inlet, and the other end of the diversion pipe body forms a plurality of heat dissipation air outlets 1211. The plurality of heat dissipation air outlets 1211 are communicated with the air inlet through the diversion pipeline. At the same time, the air inlet is communicated with the cold air outlet of the air conditioner so that the cold air generated by the air conditioner enters the plurality of heat dissipation air outlets 1211 through the air inlet.

[0044] In this embodiment, a plurality of heat dissipation outlets 1211 are arranged at intervals along a straight line direction to adapt to the structure in which the battery units in the energy storage device are arranged along a straight line, and each heat dissipation outlet 1211 is arranged corresponding to a battery unit in the energy storage device, so that the cold air generated by the air conditioner can be blown to each battery unit through the plurality of heat dissipation outlets 1211, and among the plurality of heat dissipation outlets 1211, the cross-sectional area is gradually increased from the heat dissipation outlet 1211 adjacent to the air inlet to the heat dissipation outlet 1211 away from the air inlet.

[0045] It can be understood that the air inlet can be a heat dissipation outlet 1211 located in the middle among multiple heat dissipation outlets 1211 arranged in a straight line, or it can be a heat dissipation outlet 1211 located at the edge among multiple heat dissipation outlets 1211 arranged in a straight line. Since the flow distance of the air flow from the air inlet to the corresponding heat dissipation outlet 1211 is shorter, the flow speed is faster, so that the heat dissipation outlet 1211 at this location has a larger air volume, and the heat dissipation outlet 1211 far away from the air inlet has a longer flow distance from the air inlet to the heat dissipation outlet 1211 at that location, so the flow speed is slower, so that the air volume of the heat dissipation outlet 1211 far away from the air inlet is smaller.

[0046] Based on this, the present application sets the cross-sectional areas of multiple heat dissipation outlets 1211 to be different, and among the multiple heat dissipation outlets 1211, the cross-sectional areas are gradually increased from the heat dissipation outlet 1211 adjacent to the air inlet to the heat dissipation outlet 1211 away from the air inlet, so that the heat dissipation outlet 1211 adjacent to the air inlet reduces the air outlet cross-sectional area on the basis of a faster flow rate, thereby reducing its air outlet volume, and the heat dissipation outlet 1211 away from the air inlet increases the air outlet cross-sectional area on the basis of a slower exchange, thereby increasing the air outlet volume, so that the air outlet volume of the multiple heat dissipation outlets 1211 is not affected by the relative position of the air inlet, but remains consistent, and the heat dissipation and cooling effect of the heat dissipation device at various locations of the energy storage device is kept consistent, and the temperature at each heat dissipation outlet 1211 is kept consistent, thereby improving the efficiency and effect of refrigeration and heat dissipation, reducing energy consumption, and extending the service life of the equipment.

[0047] The heat dissipation device includes an air conditioner and a diversion structure 1. The air conditioner is provided with a cold air outlet. The diversion structure 1 includes a connected base 11 and a diversion main body 12. The base 11 is connected to the air conditioner. The diversion main body 12 is provided with an air inlet and a plurality of heat dissipation air outlets 1211 communicating with the air inlet. The air inlet communicates with the cold air outlet. The plurality of heat dissipation air outlets 1211 are arranged at intervals along a straight line. From the heat dissipation air outlet 1211 adjacent to the air inlet to the heat dissipation air outlet 1211 far from the air inlet, the cross-sectional area thereof is gradually increased. The air flow velocity of the heat dissipation air outlet 1211 adjacent to the air inlet is relatively fast, and the air flow velocity of the heat dissipation air outlet 1211 far from the air inlet is relatively slow. By adjusting the cross-sectional areas of the plurality of heat dissipation air outlets 1211, the air outlet flow rates of the plurality of heat dissipation air outlets 1211 are kept consistent, so that the air flow rate flowing from the cold air outlet of the air conditioner to the plurality of heat dissipation air outlets 1211 is consistent, so that the temperatures of the cooling objects corresponding to the plurality of heat dissipation air outlets 1211 are evenly distributed, effectively improving the heat dissipation effect, increasing the overall heat dissipation efficiency, and reducing the energy consumption of the energy storage device.

[0048] In one embodiment, as Figure 1 and Figure 3 shown, the plurality of heat dissipation air outlets 1211 include a middle air outlet 1212 and a plurality of edge air outlets 1213. The middle air outlet 1212 is disposed opposite to the air inlet. The plurality of edge air outlets 1213 are arranged at intervals along a straight line on both sides of the middle air outlet 1212. The cross-sectional area of the middle air outlet 1212 is smaller than that of the edge air outlets 1213.

[0049] In this embodiment, among the plurality of heat dissipation air outlets 1211 arranged at intervals along a straight line, one or two are middle air outlets 1212, and a plurality of edge air outlets 1213 are arranged on both sides of the middle air outlet 1212. One or two middle air outlets 1212 are disposed opposite to the air inlet. The plurality of edge air outlets 1213 extend from the middle air outlet 1212 in a direction away from the middle air outlet 1212. Among them, the cross-sectional area of the middle air outlet 1212 is smaller than that of the edge air outlets 1213.

[0050] It can be understood that the cross-sectional area of the heat dissipation air outlet 1211 is the cross-sectional area of the channel of the heat dissipation air outlet 1211 along the axis direction, that is, along the cold air flow direction, which is also the air outlet cross-sectional area of the cold air passing through the heat dissipation air outlet 1211. A plurality of edge air outlets 1213 are arranged on both sides of the middle air outlet 1212 at intervals along a straight line, and the cross-sectional area of the edge air outlets 1213 located on both sides of the middle air outlet 1212 is larger than the cross-sectional area of the middle air outlet 1212. In the case where the air flow velocity is different due to different distances from the air inlet, the air output of the middle air outlet 1212 and the edge air outlets 1213 on both sides can also be kept consistent, so as to ensure the consistent air output of the plurality of heat dissipation air outlets 1211, thereby ensuring the consistent heat dissipation effect.

[0051] In one embodiment, the cross-sectional area of the edge air outlet 1213 is gradually increased from adjacent to the middle air outlet 1212 to away from the middle air outlet 1212.

[0052] It can be understood that on the basis that the cross-sectional area of the edge air outlet 1213 is larger than the cross-sectional area of the middle air outlet 1212, the cross-sectional area of the edge air outlet 1213 is gradually increased in the direction from adjacent to the middle air outlet 1212 to away from the middle air outlet 1212, so as to be not affected by the position of the edge air outlet 1213, and the same air output can be obtained from adjacent to the air inlet to away from the air inlet, so that the plurality of heat dissipation air outlets 1211 have the same air output, so as to ensure the consistent heat dissipation temperature and the consistent heat dissipation effect.

[0053] In one embodiment, as Figure 1 and Figure 3 shown, the diversion main body 12 is provided with at least three heat dissipation air outlets 1211, the number of the heat dissipation air outlets 1211 is N (N is greater than or equal to 3), the air inlet flow rate of the air inlet is F0, and the air outlet flow rate of each heat dissipation air outlet 1211 is F1, F1 = F0 / N; it can be understood that the diversion main body 12 is provided with at least three heat dissipation air outlets 1211, which can be three, five, six, eight or even ten, which is not limited herein, and the number of the heat dissipation air outlets 1211 is determined according to the number of battery units in each energy storage device. Among them, the number of the heat dissipation air outlets 1211 is N, the air inlet communicating with the cold air outlet has an air inlet flow rate of F0, and the air outlet flow rate of each heat dissipation air outlet 1211 is F1, F1 = F0 / N, so as to evenly distribute the air inlet flow rate of the air inlet among the plurality of heat dissipation air outlets 1211, so as to ensure that the air outlet flow rate of each heat dissipation air outlet 1211 is consistent.

[0054] Optionally, the cross-sectional shape of the heat dissipation air outlet 1211 is circular or square; it can be understood that the cross-sectional shape of the heat dissipation air outlet 1211 can be circular, square or other polygons, and preferably the cross-sectional shape of the heat dissipation air outlet 1211 is a regular figure, so as to facilitate calculating and obtaining the cross-sectional area of the heat dissipation air outlet 1211, and calculating the size of the cross-sectional area of the heat dissipation air outlet 1211 at different positions according to the distance to the air inlet, so as to ensure the consistency of the air volume of multiple heat dissipation air outlets 1211.

[0055] Optionally, the heat dissipation device further includes a sealing strip, and the sealing strip is arranged at the air inlet of the diversion main body 12 to seal the air inlet and the cold air outlet; it can be understood that the sealing strip is made of a soft material, such as an integrally prefabricated sealing material such as rubber, silica gel, sponge, etc., or can also be arranged at the air inlet by means of smearing and extrusion, etc., which is not limited herein. By arranging the sealing strip at the air inlet, the connection between the cold air outlet of the air conditioner and the air inlet of the diversion structure 1 can be effectively sealed, preventing cold air from leaking out from the interface, so as to ensure the effect of dissipating heat from the energy storage device.

[0056] In one embodiment, as Figure 1 and Figure 3 shown, the diversion main body 12 includes a diversion shell and an air outlet plate 121. The diversion shell is provided with a diversion cavity and an air inlet communicating with the diversion cavity; the air outlet plate 121 forms a plurality of heat dissipation air outlets 1211, and the plurality of heat dissipation air outlets 1211 communicate with the diversion cavity.

[0057] In this embodiment, the diversion shell is a shell structure. The diversion shell can be made of metal or plastic. A diversion cavity is formed inside the diversion shell, and the diversion cavity has openings at both ends. One opening is the air inlet, and the other opening is the air outlet. At the same time, the air outlet plate 121 is a plate-like structure. The air outlet plate 121 forms a plurality of heat dissipation air outlets 1211, and the air outlet plate 121 seals the air outlet of the diversion cavity, so that the air outlet communicates with the plurality of heat dissipation air outlets 1211, so that the cold air at the air inlet flows through the diversion cavity to the plurality of heat dissipation air outlets 1211.

[0058] It can be understood that by setting the flow guide shell and forming a flow guide cavity in the flow guide shell, all the cold air at the air inlet can flow through the flow guide cavity to the multiple heat dissipation air outlets 1211, effectively improving the aggregation effect of the cold air flowing out from the cold air outlet in the air conditioner, ensuring that the cold air is only blown out from the multiple heat dissipation air outlets 1211. At the same time, by setting the shape of the flow guide shell, such as setting the volume of the flow guide shell to gradually increase from the air inlet to the multiple heat dissipation air outlets 1211, the cold air can be further guided to be evenly distributed at the multiple heat dissipation air outlets 1211, so as to improve the consistency of the air volume and the heat dissipation effect at the multiple heat dissipation air outlets 1211. Moreover, by setting the air outlet plate 121, it is also convenient to set the positions, shapes and cross-sectional areas of the multiple heat dissipation air outlets 1211 to adapt to different layout modes of battery units in different energy storage devices, and to ensure that the air volumes of the heat dissipation air outlets 1211 at different positions relative to the air inlet are consistent.

[0059] In one embodiment, in the direction from the air inlet to the end connected to the heat dissipation air outlet 1211, the cross-section of the flow guide cavity is set to gradually increase.

[0060] It can be understood that by setting the cross-section of the flow guide cavity to gradually increase in the direction from the air inlet to the end connected to the heat dissipation air outlet 1211, the cold air blown into the flow guide cavity from the air inlet can be evenly diffused and preliminarily evenly distributed to the multiple heat dissipation air outlets 1211. Then, through the heat dissipation air outlets 1211 with different cross-sectional areas, the air volumes of the cold air flowing out of the heat dissipation air outlets 1211 can be further made consistent. At the same time, the cross-section of the flow guide cavity gradually increases, and it can also be set corresponding to multiple battery units at the air outlet of the flow guide cavity, and adapt to different positions and specifications of multiple battery units, improving the versatility and adaptability of the flow guide body 12 and the heat dissipation device with the flow guide body 12.

[0061] In one embodiment, the flow guide shell includes a plurality of flow guide strips, the flow guide strips are arranged on the inner wall of the flow guide cavity, and the flow guide strips extend from the air inlet in the direction of the air outlet plate 121; each two adjacent flow guide strips form a flow guide channel, and the flow guide channel communicates with the air inlet and a heat dissipation air outlet 1211.

[0062] In this embodiment, the flow guide strip is a strip-shaped structure or a retaining wall-shaped structure with a certain width and height. The flow guide strip is arranged on the inner wall of the flow guide cavity, and the flow guide strip extends along the air inlet in the direction of the multiple heat dissipation air outlets 1211. Each two flow guide strips are arranged corresponding to one side of a heat dissipation air outlet 1211. Among them, each two adjacent flow guide strips and the cavity wall of the flow guide cavity enclose a flow guide channel, so that the flow guide channel directly communicates with the air inlet and a heat dissipation air outlet 1211.

[0063] It can be understood that the flow guide strips are arranged on the inner wall of the flow guide cavity, and there is no limit to the height of the flow guide strips exceeding the inner wall of the flow guide cavity. The formed flow guide channels can directly and accurately send the cold air entering the flow guide cavity from the air inlet to each heat dissipation air outlet 1211, so as to reduce the turbulence of the cold air inside the flow guide cavity and reduce the loss of the cold air flow, so as to ensure the air volume and air outlet effect of each heat dissipation air outlet 1211. At the same time, for the flow guide channels corresponding to different heat dissipation air outlets 1211, their channel widths are also different. Based on the different positions relative to the air inlet, the length of the flow guide channel corresponding to the heat dissipation air outlet 1211 closer to the air inlet is shorter, resulting in a faster wind speed. Therefore, it is set to have a narrower channel width, while the length of the flow guide channel corresponding to the heat dissipation air outlet 1211 farther from the air inlet is longer, resulting in a slower wind speed. Therefore, it is set to have a wider channel width. That is, the widths of the multiple flow guide channels gradually increase from the corresponding middle air outlet 1212 to the corresponding multiple edge air outlets 1213 to ensure the consistency of the air volume, heat dissipation temperature and effect of the multiple heat dissipation air outlets 1211.

[0064] In one embodiment, as Figures 1 to 3 shown, the flow guide structure 1 further includes a plurality of grilles 13, and each grille 13 is arranged at a heat dissipation air outlet 1211 of the air outlet plate 121; the air outlet area of the grille 13 gradually increases in the direction from adjacent to the air inlet to away from the air inlet.

[0065] In this embodiment, a grille 13 is arranged at each heat dissipation air outlet 1211, and the grille 13 is installed on the air outlet plate 121. Each grille 13 can be formed by a plurality of parallel and spaced horizontal bars, or can be a grid-shaped grille 13 including horizontally and vertically staggered bars, etc., which is not limited here. At the same time, by changing the number of horizontal bars and / or vertical bars on the grille 13, the air outlet area of the grille 13 is adjusted. Specifically, for the grille 13 arranged at the heat dissipation air outlet 1211 adjacent to the air inlet, the number of horizontal bars and / or vertical bars on the grille 13 is larger to reduce the air outlet area of the grille 13, and for the grille 13 arranged at the heat dissipation air outlet 1211 away from the air inlet, the number of horizontal bars and / or vertical bars on the grille 13 is smaller to increase the air outlet area of the grille 13, so as to make the air volumes blown out by the multiple heat dissipation air outlets 1211 consistent.

[0066] It can be understood that when the cross-sectional areas of multiple heat dissipation air outlets 1211 are the same, or when the air volume of multiple heat dissipation air outlets 1211 cannot be accurately adjusted by only changing the cross-sectional area, the air outlet area of the grille 13 can be adjusted to adjust the air volume of multiple heat dissipation air outlets 1211, effectively improving the accuracy of adjusting the air volume of the heat dissipation air outlets 1211 and the consistency of the air volume of multiple heat dissipation air outlets 1211. At the same time, the setting of the grille 13 also makes the adjustment of the air volume more convenient and fast.

[0067] In one embodiment, the diversion structure 1 further includes a controller and multiple driving members that are electrically connected. The driving members are arranged on the air outlet plate 121. Each grille 13 is connected to the output end of a driving member, and the grille 13 is movably arranged on the air outlet plate 121; the controller controls the movement of each grille 13 through the driving member to adjust the air flow rate of each heat dissipation air outlet 1211.

[0068] In this embodiment, the controller is electrically connected to multiple driving members. The multiple driving members are arranged on the air outlet plate 121, and the output end of each driving member is connected to a grille 13, so that the grille 13 is movably arranged on the air outlet plate 121. The controller can control the movement of each grille 13 through the driving member to change the air outlet area of each grille 13. Specifically, by setting the controller, the movement of multiple grilles 13 can be dynamically controlled to dynamically control the real-time air volume of multiple heat dissipation air outlets 1211, ensuring that the air volumes of multiple heat dissipation air outlets 1211 are consistent.

[0069] At the same time, a wind meter and a temperature sensor are also provided at each heat dissipation air outlet 1211. The wind meter and the temperature sensor are electrically connected to the controller. The wind meter can detect the wind force of the heat dissipation air outlet 1211 in real time, and the temperature sensor can detect the temperature of the heat dissipation air outlet 1211 in real time, so as to transmit the real-time wind force and the real-time temperature value to the controller. The controller obtains the temperature value and the wind force value of the current heat dissipation air outlet 1211, and adjusts the relative angle of the grille 13 relative to the air outlet plate 121 in real time by controlling the driving member, so as to adjust the air outlet area of the grille 13, ensuring that the air volumes of multiple heat dissipation air outlets 1211 are consistent.

[0070] It can be understood that by setting the controller and the driving member, the automatic adjustment and real-time adjustment of the air volume of multiple heat dissipation air outlets 1211 can be realized, thereby improving the consistency of the air volume of multiple heat dissipation air outlets 1211, ensuring the accuracy of the air volume control, and thus enhancing the consistency of the heat dissipation adjustment and the consistency of the heat dissipation effect.
