Description

Technical Field

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

[0002] The air-cooled energy storage container is an energy storage device that uses air as a heat transfer medium. It is mainly used for heat dissipation of battery containers. Its basic principles include five steps: heat generation, heat conduction, air circulation, heat dissipation and temperature control. During the charging and discharging process of the energy storage battery, heat is generated inside the battery. This heat is transferred to the external surface of the battery container through the thermal conductive material. The container is equipped with a heat dissipation channel to allow air to flow through the battery module. Through natural convection or fan-assisted ventilation, the heat is dissipated into the environment, thereby ensuring that the battery does 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. The air-cooled energy storage container, through the cooperation of the top air inlet frame and the fan module and other components, can adjust the amount of cooling air entering the battery mounting frame body when the temperature inside the battery mounting frame body is too high by flipping the sealing flap, so that the cooling air can enter the interior of the multiple battery mounting frame bodies from the corresponding rectangular air inlet slots, and through the optimization of the air supply method, the cooling air can evenly contact the battery surface during the air supply process to avoid affecting the temperature uniformity, and through the cooperation of the 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 equipment.

[0004] Based on the search of the above patents and the application of existing air-cooled energy storage containers, it is understood that during the period when heat is generated inside the energy storage battery during the charging and discharging process, most air-cooled energy storage containers discharge cold air to the upper part of the container through air ducts to achieve the cooling effect. However, there will be uneven cooling during the auxiliary heat dissipation process, resulting in unsatisfactory cooling effect for some batteries.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an air-cooled energy storage container is provided to achieve a more practical purpose. Summary of the invention

[0025] Among them, a DC cabinet 203 is respectively arranged on the left and right sides of the top rear end of the equipment seat 2, and the two DC cabinets 203 are connected to the air conditioner 201. When the air conditioner 201 is actually used, any DC cabinet 203 can provide a source of electricity.

[0026] Among them, the interior of the bellows 3 is hollow in design, and four small fans are arranged on the left and right sides of the bellows 3, and two large fans are arranged at the front end of the bellows 3. A mesh pad 302 is arranged at the front end position of the interior of the air duct 301, and a telescopic rod 303 is arranged at the middle position of the rear end of the mesh pad 302. The telescopic rod 303 is provided with a sensor element, and the rear end position of the telescopic rod 303 is in contact with the front end position of the conical sealing block 306.

[0027] Among them, the control frame 4 is fixedly connected to the middle position of the top front end of the equipment seat 2, and a partition 401 is fixedly installed at the internal front end position of 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 internal front end position of 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 at the internal position of the control frame 4.

[0028] Among them, the internal position of the control frame 4 is slidably connected with an adjustment block 403, the front end position of the adjustment block 403 is provided with a threaded hole, the rotating shaft of the motor 402 is located in the threaded hole of the adjustment block 403, and an extension seat is provided in the middle position of the top rear end of the adjustment block 403, and a guide fan 404 is provided in the middle position of the top of the extension seat of the adjustment block 403, the guide fan 404 is located in the middle front position of the two large fans at the front end of the bellows 3, and the guide fan 404 is located in the middle position of the two battery packs 5, and the top front end position of the adjustment block 403 is fixedly connected with a diverter plate 405, the diverter plate 405 is designed in the shape of a triangular column, and the two side surfaces of the rear end of the diverter plate 405 are provided with diverter grooves with the back higher and the front lower, and the cold air will be transferred to the lower sides of the diverter plate 405 for processing, so as to further improve the dispersion effect of the cold air and cool down and dissipate the heat of the two battery packs 5.

[0029] Among them, a box door 101 is symmetrically rotated and connected to the left and right sides of the front end of the container body 1, and the two box doors 101 are closed to seal the internal space of the container body 1, and an air inlet louver fan 102 is arranged at the lower position of the rear end of the container body 1, and an air outlet louver fan 103 is arranged at the upper position of the rear end of the container body 1, and the air outlet louver fan 103 is located directly above the air inlet louver fan 102, and an outer cover 104 is arranged above the air inlet louver fan 102. The air inlet louver fan 102 is connected to the air inlet position of the air conditioner 201, and the air outlet louver fan 103 is connected to the discharge position of the air conditioner 201. When the air conditioner 201 is taking in air, the air inlet louver fan 102 and the air outlet louver fan 103 are both in an open state, which is convenient for the air conditioner 201 to take in and out air. The design of the outer cover 104 prevents the air conditioner 201 from inhaling hot air discharged by the air outlet louver fan 103 of the air conditioner 201 through the air inlet louver fan 102 during the air intake process.

[0030] When using: The two battery packs 5 arranged inside the container body 1 are charged and discharged through the two DC cabinets 203. Any DC cabinet 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 inside of the container body 1 through the air duct 202. At this time, there is cold air inside the container body 1 and the air density will gradually increase and decrease, thereby cooling the two battery packs 5 placed on both sides above the equipment seat 2.

[0031] Based on the link that the air duct 202 provided in the first embodiment releases the cold air from the air conditioner 201 to cool the inside of the container body 1, it is difficult to ensure that the cooling efficiency of the two battery packs 5 is synchronized, so there is a cooling deviation. At this time, the sensor element designed by the telescopic rod 303 itself can be extended. When the telescopic rod 303 is extended, it will drive the conical sealing block 306 to slide backward in the internal position of the air duct 301. The spring member 305 is in a contracted state, and the air duct 301 is combined with the auxiliary air cooling port position at the front end of the air conditioner 201. The auxiliary air cooling port at the front end of the air conditioner 201 conveys the cold air to the internal position of the bellows 3 through the air duct 301. At this time, the four small fans on both sides of the bellows 3 and the two large fans at the front end are started respectively, and the cold air inside the bellows 3 is conveyed to the two sides and the front position, so as to assist the heat dissipation effect of the two battery packs 5.

[0032] In addition, while the two large fans at the front end of the bellows 3 are blowing cold air to the front, the guide fan 404 is started. The guide fan 404 can speed up the transmission of cold air from the bellows 3 by the two large fans to the front, thereby achieving the effect of rapid cold air transmission. The cold air drawn by the guide fan 404 will directly blow the diverter plate 405. Combined with the rear-high and front-low diverter grooves on both sides of the rear end of the diverter plate 405 to limit the transmission of cold air, the cold air will be transmitted to the lower sides of the diverter plate 405 for processing, thereby further improving the dispersion effect of the cold air and cooling the two battery packs 5.

[0033] When the motor 402 is started, the shaft thread of the motor 402 cooperates with the threaded hole of the adjustment block 403, so that the adjustment block 403 can be slidably adjusted in the front and rear position inside the control frame 4, thereby changing the position of the guide fan 404 and the diverter plate 405, and adjusting the area where the diverter plate 405 is located between the two battery packs 5, thereby adjusting the diversion position of the cold air.

[0034] The above are only specific implementations of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and the protection scope of the present disclosure shall be based on the protection scope of the claims.
