[0034] Please also read Figures 1 to 4The utility model proposes a cooling box 1000, which includes a frame 100, a cooling device 200 and a plurality of air inlet structures 300; the frame 100 has a plurality of cooling chambers 110, an air inlet channel 120 and an air outlet channel 130, the plurality of cooling chambers 110 are arranged at intervals in the vertical direction, and the air inlet channel 120 and the air outlet channel 130 are both connected to the cooling chamber 110; the two ends of the cooling device 200 are respectively connected to the air inlet channel 120 and the air outlet channel 130, so as to cool the cooling chamber 110 through the air inlet channel 120 and the air outlet channel 130; the plurality of air inlet structures 300 are arranged in a one-to-one correspondence with the plurality of cooling chambers 110, each air inlet structure 300 is respectively installed at the connection between the corresponding cooling chamber 110 and the air inlet channel 120, and the air inlet structure 300 is provided with an air inlet hole 310 with an adjustable opening area.

[0035] The rack 100 can be made of many materials. The rack 100 can be made of metal materials, the rack 100 can also be made of harder plastic, and the rack 100 can also be made of other materials, which are not specifically limited here. There are many installation positions for the cooling device 200. The cooling device 200 can be installed in the rack 100, and the cooling device 200 can also be placed outside the rack 100, and connected to the air inlet channel 120 and the air outlet channel 130 through pipelines, which are not specifically limited here. The air inlet of the air inlet channel 120 can be located at the top of the rack 100, the air inlet of the air inlet channel 120 can also be located in the middle of the rack 100, and the air inlet of the air inlet channel 120 can also be located at the bottom of the rack 100, which are not specifically limited here.

[0036] According to the technical solution of the utility model, the cooling box 1000 includes a frame 100, a cooling device 200 and a plurality of air inlet structures 300; wherein the frame 100 has a plurality of cooling chambers 110, an air inlet channel 120 and an air outlet channel 130, the plurality of cooling chambers 110 are arranged at intervals in the vertical direction, and the air inlet channel 120 and the air outlet channel 130 are both connected to the cooling chamber 110; the two ends of the cooling device 200 are respectively connected to the air inlet channel 120 and the air outlet channel 130 to cool the cooling chamber 110 through the air inlet channel 120 and the air outlet channel 130; the plurality of air inlet structures 300 are arranged in one-to-one correspondence with the plurality of cooling chambers 110, each air inlet structure 300 is respectively installed at the connection between the corresponding cooling chamber 110 and the air inlet channel 120, and the air inlet structure 300 is provided with an air inlet hole 310 with an adjustable opening area. In this way, the technical solution of the utility model can adjust the opening area of ​​the air inlet hole 310 of each air inlet structure 300 so that the opening area of ​​the air inlet hole 310 of each air inlet structure 300 gradually decreases in the direction close to the air outlet of the cooling device 200, thereby making the air intake volume of each cooling cavity 110 the same, thereby ensuring that the cooling efficiency of each cooling cavity 110 for the battery is the same.

[0037] Please also read Figures 1 to 4 In some embodiments of the present utility model, the air inlet structure 300 includes a fixed plate 320 and an adjusting plate 330. The fixed plate 320 is fixedly installed at the connection between the cooling cavity 110 and the air inlet channel 120, and the fixed plate 320 is provided with a first through hole 321; the adjusting plate 330 is movably installed on the fixed plate 320, and the adjusting plate 330 is provided with a second through hole 331, so as to adjust the opening area of ​​the air inlet hole 310 by adjusting the relative position of the second through hole 331 and the first through hole 321. In this way, the wind in the air inlet channel 120 can only enter the corresponding cooling cavity 110 through the overlapping part of the first through hole 321 and the second through hole 331. It can be understood that the overlapping part of the first through hole 321 and the second through hole 331 is the air inlet hole 310, and the opening area of ​​the air inlet hole 310 is changed by moving the position of the adjusting plate 330 to change the size of the overlapping part of the first through hole 321 and the second through hole 331.

[0038] It should be noted that the number of the first through holes 321 can be multiple, and the second through holes 331 are arranged in a one-to-one correspondence with the first through holes 321. It can be understood that the air inlet hole 310 is composed of the overlapping part of each first through hole 321 and the corresponding second through hole 331, and the opening area of ​​the air inlet hole 310 is adjusted by moving the adjustment plate 330 to adjust the size of the overlapping part between each first through hole 321 and the corresponding second through hole 331.

[0039] Please also read Figures 1 to 4 In some embodiments of the utility model, the frame 100 is penetrated by a plurality of threaded holes 140, and the plurality of threaded holes 140 are arranged one by one corresponding to the plurality of air inlet structures 300; the air inlet structure 300 also includes a connecting block 340, a rotating member 350 and a bearing 360, the connecting block 340 is fixedly mounted on the adjusting plate 330, one end of the rotating member 350 passes through the threaded hole 140 and is connected to the connecting block 340 through the bearing 360, one end of the rotating member 350 is also provided with a thread threadedly connected to the threaded hole 140, and the other end of the rotating member 350 extends out of the cooling box 1000.

[0040] In this arrangement, by rotating the rotating member 350 so that the thread on the rotating member 350 cooperates with the threaded hole 140, the rotating member 350 is driven to move relative to the frame 100, thereby pulling the connecting block 340 to move to drive the adjustment plate 330 to move relative to the fixed plate 320, thereby adjusting the opening area of ​​the air inlet hole 310. At the same time, under the action of the bearing 360, the rotating member 350 can rotate relative to the connecting member and can pull the connecting member to move.

[0041] Please also read Figures 1 to 4In some embodiments of the utility model, the rack 100 is provided with a guide rail 150, which extends along the length direction of the fixed plate 320, and a guide block 332 is provided on the surface of the adjustment plate 330, and a guide groove 333 is recessed on the surface of the guide block 332 facing the guide rail 150, and the guide groove 333 is arranged to penetrate along the length direction of the fixed plate 320 and is slidably connected with the guide rail 150. In this way, the guide block 332 cooperates with the guide rail 150 to guide the movement of the adjustment plate 330, and at the same time, the two groove walls of the guide groove 333 in the direction of approaching or moving away from the fixed plate 320 cooperate with the guide rail 150 to limit the adjustment plate 330 in the direction of approaching or moving away from the fixed plate 320, thereby preventing the adjustment plate 330 from separating from the fixed plate 320.

[0042] Furthermore, the surface of the adjustment plate 330 facing the guide rail 150 is provided with a stopper 334, which can abut against the surface of the guide rail 150 in the length direction of the fixing plate 320 to limit the position of the adjustment plate 330. In this way, the adjustment plate 330 is limited by the abutment of the stopper 334 against the guide rail 150, thereby preventing the adjustment plate 330 from moving too far and causing the guide block 332 to separate from the guide rail 150.

[0043] It should be noted that the length direction of the fixed plate 320 can be understood as the movement direction of the adjustment plate 330. There are many ways to install the limiter 334. The limiter 334 can be integrally formed with the adjustment plate 330, or the limiter 334 can be detachably installed on the adjustment plate 330. Preferably, the limiter 334 can be detachably installed on the adjustment plate 330, so that the staff only needs to match the guide block 332 of the adjustment plate 330 with the guide rail 150, and then install the limiter 334 on the adjustment plate 330, thereby avoiding interference between the limiter 334 and the guide rail 150 when the adjustment plate 330 is installed on the fixed plate 320.

[0044] The number of the guide rails 150 can be multiple, and the guide block 332 is arranged in a one-to-one correspondence with the number of the guide rails 150. The limiter 334 is located between two adjacent guide rails 150 in the length direction of the fixed plate 320, so that the motion range of the adjustment plate 330 can be better limited. The number of the limiter 334 can be two, and the two limiters 334 are both located between two adjacent guide rails 150 in the length direction of the fixed plate 320, so that the motion range of the adjustment plate 330 can be reduced, so that the first through hole 321 can only cooperate with the corresponding second through hole 331, thereby facilitating the use of the air intake structure 300 by the staff.

[0045] Please also read Figures 1 to 4In some embodiments of the present invention, the cooling device 200 includes an air circulation module (not shown) and a heat exchange module (not shown), the air outlet of the air circulation module is connected to the air inlet channel 120, and the air inlet of the air circulation module is connected to the air outlet channel 130; the heat exchange module is located in the air circulation module to cool down the air in the air circulation module.

[0046] With such a configuration, the air is circulated in the air inlet channel 120, the cooling chamber 110 and the air outlet channel 130 through the air circulation module, and then the air in the air circulation module is cooled by the heat exchange module to reduce the temperature of the wind in the air inlet channel 120. Therefore, after the wind in the air inlet channel 120 enters the cooling chamber 110, the battery in the cooling chamber 110 can be better cooled, thereby improving the cooling efficiency of the cooling box 1000.

[0047] Please also read Figures 1 to 4 In some embodiments of the present invention, the cooling box 1000 further includes an air guide plate 400, which is installed in the air inlet channel 120, and the air guide plate 400 is tilted in the direction away from the air inlet of the air inlet channel 120 toward the direction close to the cooling cavity 110. In this way, the air guide plate 400 is tilted so that the wind away from the air inlet of the air inlet channel 120 can better enter the cooling cavity 110 away from the air inlet of the air inlet channel 120, thereby increasing the air volume entering the cooling cavity 110 away from the air inlet of the air inlet channel 120, thereby improving the cooling efficiency of the cooling cavity 110 away from the air inlet of the air inlet channel 120.

[0048] Please also read Figures 1 to 4 In some embodiments of the utility model, the cooling cavity 110 is provided with a feed port 111, and the cooling box 1000 further includes a cover plate 500, which is rotatably mounted on the feed port 111 to open or close the feed port 111. In this arrangement, the cover plate 500 is first rotated to open the feed port 111, and then the battery is placed in the cooling cavity 110 through the feed port 111, and then the cover plate 500 is rotated to close the feed port 111, and the cooling device 200 is started to work to complete the cooling operation, thereby facilitating the operation of the staff.

[0049] Furthermore, the cooling box 1000 further includes a driving device 600, which is installed in the cooling chamber 110 and is drivingly connected to the cover plate 500 to drive the cover plate 500 to open or close the feed port 111. In this way, the cover plate 500 can be controlled to open or close the feed port 111 by controlling the driving device 600, thereby improving the automation of the cooling box 1000.

[0050] Please also read Figures 1 to 4In some embodiments of the utility model, the air inlet of the air inlet channel 120 and the air outlet of the air outlet channel 130 are both located at the top of the frame 100; the cooling box 1000 further includes a support frame 700, the support frame 700 has a support surface 710 close to the top of the frame 100, and the cooling device 200 is installed on the support surface 710. In this way, the cooling device 200 is placed close to the air inlet of the air inlet channel 120 and the air outlet of the air outlet channel 130 through the support frame 700, so as to reduce the movement stroke of the wind blown out by the cooling device 200, thereby improving the cooling efficiency of the cooling box 1000.

[0051] It should be noted that the staff can move to the support surface 710 via a ladder to maintain the cooling device 200 , and can also check the top of the rack 100 and maintain the inlet and outlet channels 130 , which makes it easier for the staff to maintain the cooling box 1000 .
