Description

Technical Field

[0001] The present invention relates to the technical field of energy storage containers, and particularly to an air-cooled energy storage container. Background Art

[0002] ‌An air-cooled energy storage container is an energy storage device that uses air as a heat transfer medium, mainly for the heat dissipation of battery containers. Its basic principle includes five steps: heat generation, heat conduction, air circulation, heat dissipation, and temperature control. During the charging and discharging process of energy storage batteries, heat is generated inside the batteries. These heats are transferred to the outer surface of the battery container through heat-conducting materials. There are heat dissipation channels inside the container to allow air to flow through the battery modules. By means of natural convection or fan-assisted ventilation, the heat is dissipated into the environment, thus ensuring that the batteries do not overheat.

[0003] Application No. CN202410509571.1. The present invention discloses an air-cooled energy storage container, which relates to the technical field of energy storage containers. This air-cooled energy storage container, through the cooperation of components such as a top air intake frame and a fan module, when in use, when the temperature inside the battery mounting frame body is too high, the intake amount of cooling air can be adjusted by the flipping of the sealing flap, enabling the cooling air to enter the inside of multiple battery mounting frame bodies through the corresponding rectangular air intake slots. Through the optimization of the air supply method, the cooling air can evenly contact the battery surface during the air supply process, avoiding affecting the temperature uniformity, and through the cooperation of an air-water cooler, the output hot air can be heat-exchanged through the air duct to take away the heat, further improving the heat dissipation effect of the device.

[0004] Based on the retrieval of the above patent and the understanding of the application of existing air-cooled energy storage containers: during the period when heat is generated inside during the charging and discharging process of energy storage batteries, most air-cooled energy storage containers discharge cold air to the upper position inside the container through the air duct to achieve the cooling effect. However, during the auxiliary heat dissipation process, there will be an uneven cooling situation, resulting in an unsatisfactory cooling effect for some batteries.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an air-cooled energy storage container is provided, with the expectation of achieving a more practical purpose. Summary of the Invention

A spring member 305 is fixedly connected to the front end position of the limiting ring 304. The front end position of the spring member 305 is connected to the rear end position of a conical sealing block 306. A sealing strip is arranged on the front conical surface position of the conical sealing block 306. When the spring member 305 is in an extended state, the front end position of the conical sealing block 306 fits the conical groove position of the air duct 301. A set of battery packs 5 are respectively placed on the left and right sides at the top of the device seat 2. The two battery packs 5 are symmetrically distributed on the left and right sides of the wind box 3. A smoke alarm 6 is installed at the top of the wind box 3.

[0036] Among them, a DC cabinet 203 is respectively arranged at the left and right sides at the rear end of the top of the device seat 2. Both DC cabinets 203 are connected to the air conditioner 201. When the air conditioner 201 is actually used, the power supply can be provided by any one of the DC cabinets 203.

[0037] Among them, the inside of the wind box 3 is hollow-designed, and four small fans are arranged on both the left and right sides of the wind box 3. Two large fans are arranged at the front end of the wind box 3. A mesh through-pad 302 is arranged at the front end position inside the air duct 301. A telescopic rod 303 is arranged at the middle position at the rear end of the mesh through-pad 302. The telescopic rod 303 is provided with a sensor element. The rear end position of the telescopic rod 303 is in contact with the front end position of the conical sealing block 306.

[0038] Among them, a control frame 4 is fixedly connected to the middle position at the front end of the top of the device seat 2. A partition 401 is fixedly installed at the front end position inside the control frame 4. A motor 402 is arranged at the front end position of the partition 401. The motor 402 is located at the front end position inside the control frame 4. The rotating shaft of the motor 402 is provided with a thread, and the rotating shaft of the motor 402 is located inside the control frame 4.

[0039] Among them, an adjusting block 403 is slidably connected to the inner position of the control frame 4. A threaded hole is provided at the front end of the adjusting block 403. The rotating shaft of the motor 402 is located in the threaded hole of the adjusting block 403. An extension seat is provided at the middle position of the rear end of the top of the adjusting block 403, and a guiding fan 404 is provided at the middle position of the top of the extension seat of the adjusting block 403. The guiding fan 404 is located in the middle front position between the two large fans at the front end of the air box 3 and is located at the middle position between the two battery packs 5. A flow dividing plate 405 is fixedly connected to the front end position of the top of the adjusting block 403. The flow dividing plate 405 is designed in the shape of a triangular prism, and flow dividing grooves with a higher rear end and a lower front end are provided on both side surfaces of the rear end of the flow dividing plate 405. The cold air will be transferred to the lower sides on both sides of the flow dividing plate 405, further improving the dispersion effect of the cold air and cooling and dissipating heat from the two battery packs 5.

[0040] Among them, a door 101 is symmetrically and rotatably connected to the left and right sides at the front end of the container body 1. The two doors 101 are closed to enclose the internal space of the container body 1. An air inlet louvre fan 102 is provided at the lower position at the rear end of the container body 1, and an air outlet louvre fan 103 is provided at the upper position at the rear end of the container body 1. The air outlet louvre fan 103 is located directly above the air inlet louvre fan 102. An outer cover 104 is provided above the air inlet louvre fan 102. The air inlet louvre fan 102 is connected to the air inlet position of the air conditioner 201, and the air outlet louvre fan 103 is connected to the discharge position of the air conditioner 201. When the air conditioner 201 intakes air, both the air inlet louvre fan 102 and the air outlet louvre fan 103 are in an open state, facilitating the air intake and exhaust of the air conditioner 201. The design of the outer cover 104 prevents the air conditioner 201 from inhaling the hot air discharged through the air outlet louvre fan 103 during the air intake process through the air inlet louvre fan 102.

[0041] During use:

[0042] Two battery packs 5 arranged inside the container body 1 perform charging and discharging processes through two DC cabinets 203. Any one of the DC cabinets 203 provides relative energy for the air conditioner 201. The cold air generated by the air conditioner 201 will be released to the left and right sides above the interior of the container body 1 through the air duct 202. At this time, the cold air existing inside the container body 1 will cause the air density to gradually increase and descend to cool the two battery packs 5 placed on both sides above the equipment seat 2.

[0043] In the process of using the air duct 202 provided in the first embodiment to release the cold air of the air conditioner 201 to cool the interior of the container body 1, it is difficult to ensure the synchronous cooling efficiency of the two battery packs 5. Therefore, there is a cooling deviation. At this time, the sensor element designed in the telescopic rod 303 can be used for extension. When the telescopic rod 303 extends, it will drive the conical seal block 306 to slide backward inside the air duct 301. The spring member 305 is in a contracted state. Considering that the air duct 301 is connected to the front auxiliary air-cooling port of the air conditioner 201, the front auxiliary air-cooling port of the air conditioner 201 conveys the cold air to the inside of the air box 3 through the air duct 301. At this time, four small fans on both sides of the air box 3 and two large fans at the front end are respectively started to convey and transfer the cold air inside the air box 3 to both sides and the front, so as to play an auxiliary heat dissipation effect on the two battery packs 5.

[0044] In addition, during the process of the two large fans at the front end of the air box 3 blowing the cold air forward, the guiding fan 404 is started. The guiding fan 404 can accelerate the transmission of the cold air in the air box 3 by the two large fans to the front, achieving the effect of rapid cold air transmission. And the cold air drawn by the guiding fan 404 will directly blow the diversion plate 405. Considering the rear-high and front-low diversion grooves opened on both sides of the rear end of the diversion plate 405 to limit the transmission of the cold air, the cold air will be transmitted and processed downward on both sides of the diversion plate 405, further improving the dispersion effect of the cold air and cooling and dissipating heat from the two battery packs 5.

[0045] When the motor 402 is started, the rotating shaft of the motor 402 is threadedly engaged with the threaded hole of the adjusting block 403, so that the adjusting block 403 slides and adjusts in the front-back position inside the control frame 4, thereby changing the positions of the guiding fan 404 and the diversion plate 405, and adjusting the area position of the diversion plate 405 located in the middle of the two battery packs 5 to adjust the diversion position of the cold air.

[0046] The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. The protection scope of the present disclosure shall be subject to the protection scope of the claims.
