[0003] However, the heat dissipation system of the traditional container energy storage system is single, and the heat dissipation uniformity is poor. In an environment with high temperature or large temperature difference, the operating efficiency of its battery pack and other equipment is low, the lifespan is shortened, and at the same time, the excessive temperature difference may cause some failures, resulting in unnecessary economic losses. Summary of the Invention

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the present invention is to provide a swirl heat dissipation device for a container energy storage system. This heat dissipation device can effectively dissipate heat evenly, and make the cold air in the heat dissipation system evenly distributed horizontally. It can also be adjusted according to the performance requirements of the environment where the system is located, and has strong applicability. To achieve the above-mentioned purpose and other advantages of the present invention, there is provided a swirl heat dissipation device for a container energy storage system, including:

[0005] A box body, a refrigeration mechanism fixed inside the box body, a wind wall mechanism communicated with the refrigeration mechanism, and a plurality of swirl heat dissipation mechanisms fixed at the bottom of the box body;

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Refer to Figures 1-3, A swirl heat dissipation device for a container energy storage system, comprising: a box body 10, a refrigeration mechanism 30 fixed inside the box body 10, a wind wall mechanism 40 communicated with the refrigeration mechanism 30, and a plurality of swirl heat dissipation mechanisms 20 fixed at the bottom of the box body 10. Cold air is generated inside the box body 10 by the refrigeration mechanism 30, and the cold air is brought into the box body 10 through the wind wall mechanism 40. When the cold air blows out from the wind wall mechanism 40, a tangential swirl is generated by the swirl heat dissipation mechanism 20, so that the cold air blown out from the wind wall mechanism 40 is evenly distributed inside the box body 10. A refrigeration mechanism 30 is fixed on one end face of the box body 10. The refrigeration mechanism 30 includes a refrigerator 31 and a duct 32 communicated with the refrigerator 31. The duct 32 extends along the length direction of the box body 10. The cold air generated by the refrigerator 31 first enters the duct 32, and the cold air is transmitted along the length direction of the duct 32. The wind wall mechanism 40 includes a first wind wall 41 and a second wind wall 42 arranged opposite to the first wind wall 41. The first wind wall 41 and the second wind wall 42 are respectively fixed on opposite side surfaces of the box body 10. The structures of the first wind wall 41 and the second wind wall 42 are the same. The inside of the first wind wall 41 is hollow and a plurality of air outlets 43 are opened on the surface close to the second wind wall 42. A heat dissipation interval is formed between the first wind wall 41 and the second wind wall 42. When the battery pack is placed in this heat dissipation interval, the cold air generated by the refrigerator 31 enters the wind wall through the duct. The cold air in the wind wall is blown into the heat dissipation interval through the air outlets 43 to dissipate heat from the battery pack. The swirl heat dissipation mechanism 20 includes a motor fixed inside the swirl housing and a connecting rod 21 fixedly connected to the output shaft of the motor. At least two swirl plates 22 are fixedly sleeved on the connecting rod 21, and fan blades 23 located on the swirl plates 22 and fixedly connected to the connecting rod 21. When the motor rotates, the output shaft of the motor drives the connecting rod 21 to rotate, and the fan blades 23 and the swirl plates 22 are fixedly connected to the connecting rod 21, so that the fan blades 23 and the swirl plates 22 rotate, thereby generating a tangential swirl relative to the wind wall.

[0029] Further, the cooler 31 is an air conditioner. An air duct 32 is connected to the air outlet of the air conditioner. The air duct 32 includes a first air duct and a second air duct. The first air duct and the second air duct are oppositely arranged and have the same structure. The air outlet of the air conditioner is connected to both the first air duct and the second air duct at the same time. One end of the first air duct is connected to the air outlet of the air conditioner, and the other end penetrates through the first air wall 41 and extends along the length direction of the first air wall 41. One end of the second air duct is connected to the air outlet of the air conditioner, and the other end penetrates through the second air wall 42 and extends along the length direction of the second air wall 42. A plurality of air guiding vanes 50 are fixedly connected to the second air duct, and a plurality of air guiding vanes 50 are fixedly connected to the first air duct. The air guiding vanes 50 blow the cold air in the air duct 32 into the air wall to prevent the cold air from being transmitted along the air duct 32 and unable to automatically enter the air wall, so that the first air duct and the second air duct can be filled with cold air at the same time, so that the first air wall 41 and the second air wall 42 are filled with cold air and work at the same time, improving the heat dissipation efficiency.

[0030] Further, a row of air outlets 43 is vertically opened on the first air wall 41 at the position of the air guiding vanes 50. Each row of air outlets 43 includes at least two horizontally parallel air outlets 43. An adjustable grille is provided in the air outlets 43. The air outlets 43 are set to be adjustable in size and direction. When the environment where the system is located or the heat dissipation performance requirement of the system changes, corresponding adjustments can be made to increase the adaptability of the entire swirl heat dissipation system. The air wall is provided with air outlets 43 opposite to the air guiding vanes 50 of the split air outlets 43. When the air guiding vanes 50 blow the cold air in the vertical direction, the air outlets 43 are at the direction of the cold air blown by the air guiding vanes 50 at this time, so that the cold air can flow out from the air outlets 43 on the air wall. Appropriate air outlets 43 are set to avoid the chaotic flow of cold air, resulting in uneven distribution of cold air and failing to achieve the best heat dissipation effect.

[0031] Further, at least one swirl heat dissipation mechanism 20 is provided at each row of air outlets 43 on the first air wall 41 and the second air wall 42. Through the rotation of the fan blades 23 and the swirl plate 22, the swirl heat dissipation mechanism 20 will generate a tangential swirl relative to the air wall, thereby driving the cold air at the air outlets 43 to flow out from the air outlets 43 and evenly distributing it in the box body 10.

[0032] Refer to Figure 3, the swirl plate 22 includes an annular fixing ring and helical fins fixed to the annular fixing ring. One end of each helical fin is fixed to the inner wall of the annular fixing ring, and the other end is fixed to the connecting rod 21. A plurality of helical fins are evenly distributed along the inner wall of the annular fixing ring in a circle, and the helical direction of each helical fin is the same. The fan blades 23 are elliptical and helical along their axial directions. A plurality of fan blades 23 are evenly fixed along the outer circumference of the connecting rod 21 in a circle, and the helical direction of each fan blade 23 is the same. By fixedly connecting a plurality of such swirl plates 22 to the connecting rod 21, a large swirl can be generated. Moreover, the helical directions of the helical fins and the fan blades 23 on the swirl plate 22 are the same. Through the rotation of the plurality of swirl plates 22 and the fan blades 23, sufficient tangential swirl is generated to drive the cold air to be evenly distributed in the box body 10.

[0033] Further, an exhaust fan 60 is fixed on the end face of the box body 10 away from the air conditioner. The exhaust fan 60 can adjust the exhaust efficiency. According to the temperature condition in the box body 10, the exhaust fan 60 cooperates with the air conditioner to control the forced convection intensity in the equipment bin.

[0034] Further, a temperature measuring instrument 70 is fixedly connected to the inner top surface of the box body 10. The temperature measuring instrument 70 is an intelligent temperature measuring instrument 70, which can monitor the temperature of the equipment bin in real time so as to take corresponding measures.

[0035] Working principle: An air conditioner is installed on one side of the box body 10. The air outlet of the air conditioner is connected to the first air duct and the second air duct. The first air duct penetrates through the first air wall 41, and the second air duct penetrates through the second air wall. Air guide vanes 50 are provided on both the first air duct and the second air duct. The cold air generated by the air conditioner passes through the air duct 32 and then is introduced into the air wall through the air guide vanes 50. A plurality of swirl heat dissipation mechanisms 20 are installed at the first air wall 41 and the second air wall 42. When the cold air enters the air outlet 43 of the air wall, at this time, the motor in the swirl heat dissipation mechanism 20 drives the swirl plate 22 and the fan blades 23 to rotate, generating a tangential swirl relative to the air wall, driving the cold air at the air outlet 43 to be evenly distributed in the box body 10. Moreover, an adjustment grille is provided at the air outlet 43. When the temperature in the box body 10 is too high, at this time, the adjustment grille is fully opened, so that the size of the air outlet 43 is at the maximum size, and more cold air is blown out, improving the heat dissipation efficiency. When the temperature in the box body 10 is appropriate, the adjustment grille can be adjusted to make the opening of the air outlet 43 have an appropriate size to dissipate heat from the battery pack and equipment to be cooled. By installing an intelligent temperature measuring instrument 70 on the top of the box body 10, the temperature of the equipment bin can be monitored in real time so as to take corresponding measures. An exhaust fan 60 with adjustable exhaust efficiency is installed on one side of the box body 10. According to the temperature condition in the box body 10, it cooperates with the air conditioner to control the forced convection intensity in the equipment bin.
