Description

Technical Field

[0001] The utility model relates to the technical field of battery boxes, in particular to a multi-stage heat dissipation battery box based on an energy storage system. Background Art

[0002] Energy storage systems mostly refer to systems that store electricity. Nowadays, electricity storage still involves storing excess electricity in batteries. Batches of batteries are mostly placed in dedicated battery boxes. During the process of storing electricity, the batteries need to be continuously charged, which will cause the battery temperature to gradually increase. If the battery works in a high temperature environment for a long time, it will first reduce its own service life and at the same time may spontaneously combust, causing greater losses.

[0003] The patent application number CN202220612614.5 discloses a low-cost energy storage battery box, including an upper box cover, a module and a lower box. The module is vertically hoisted into the interior of the lower box, the bottom of the module is in contact with the inner side of the bottom of the lower box, the mounting surfaces on both sides of the module are locked and fixed to the two sides of the lower box, and the upper box cover is installed on the top of the lower box; the module includes a sheet metal module and a battery, and the sheet metal module and the battery are tightly bundled with high-strength module strapping tape. A mounting bracket for structural reinforcement is provided on the bottom of the lower box, and a module fixing structure is provided on the outside of the lower box on the short side.

[0004] This technical solution does not include a heat dissipation structure inside the lower case. Therefore, when the batteries are operating or charging, they can only dissipate heat through the outer wall of the lower case. This has a low heat dissipation rate and cannot quickly dissipate the heat generated by the batteries. As a result, heat will still accumulate inside the lower case after the batteries have been operating for a long time, causing the batteries to operate in a high temperature environment. In view of this, we propose a multi-stage heat dissipation battery box based on an energy storage system. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a multi-stage heat dissipation battery box based on an energy storage system.

[0006] The technical solution of the utility model is:

[0008] As an optimal technical solution, the placement box is located on the front and rear inner walls of one side of the air supply plate and is equipped with several equally spaced partitions. Batteries are placed between two adjacent partitions, and the air supply plate is placed on the batteries, with the air outlet at its bottom opened between the two batteries.

[0009] As a preferred technical solution, the fins are located on the front and rear outer walls of the placement box, air outlet mesh holes are provided on the front and rear sides of the box cover directly above the battery, and air inlet mesh holes are provided above the heat dissipation box, and the left and right sides of the box cover are hinged with an external clip, and each of the external clips is snap-connected to an internal clip fixed to the outer wall of the placement box.

[0010] As an optimal technical solution, the bottom of the placement box is located below the heat dissipation box and is connected to an extension box. The distance between the bottom of the extension box and the top of the placement box is greater than the length of the air supply plate. A placement gap for the air supply plate is provided on the top of the insulation board, and the air supply pipe is a hose.

[0011] As a preferred technical solution, two legs are symmetrically installed on the left side of the bottom of the placement box, and the bottoms are flush with the bottom of the extension box.

[0025] Example 1

[0026] A multi-stage heat dissipation battery box based on an energy storage system includes a storage box 1 and a box cover 2. A number of evenly distributed fins 11 are installed on the outer wall of the storage box 1. A heat insulation board 16 is installed inside the storage box 1 and a heat dissipation box 14 is installed on one side of the heat insulation board 16. A mesh plate 140 is installed at the top of the heat dissipation box 14. At least one heat dissipation blade 141 is installed on the top of the mesh plate 140. A motor for driving the heat dissipation blade 141 to rotate is installed at the bottom of the mesh plate 140. Two semiconductor refrigeration plates 142 are symmetrically installed on the lower part of the interior of the heat dissipation box 14. An air supply plate 15 is provided on the other side of the heat insulation board 16 in the storage box 1. The air supply plate 15 is connected to the lower part of the interior of the heat dissipation box 14 through an air supply pipe 150. The fins 11 can directly dissipate heat from the storage box 1 and the battery 3 inside it. The two semiconductor refrigeration plates 142 installed in the heat dissipation box 14 can cool the air passing through them and send it to the air supply plate 15 through the air supply pipe 150 to directly cool the battery 3. This forms multi-stage cooling, which can keep the operating temperature of the battery 3 at a low level.

[0027] As a preferred embodiment of this embodiment, a plurality of equally spaced partitions 13 are installed on the front and rear inner walls of the storage box 1, located on one side of the air supply plate 15. Batteries 3 are placed between two adjacent partitions 13. The air supply plate 15 is placed on the batteries 3, and the air outlet at its bottom is located between the two batteries 3. The partitions 13 separate the two adjacent batteries 3, thereby increasing the heat dissipation surface of the batteries 3 and accelerating the heat dissipation of the batteries 3. The air outlet on the air supply plate 15 is located between the two batteries 3, blowing cold air between the two batteries 3, thereby cooling both batteries 3 simultaneously.

[0028] As a preferred embodiment of this embodiment, fins 11 are located on the front and rear outer walls of the storage box 1. Air outlet mesh holes 20 are provided on the front and rear sides of the box cover 2 directly above the battery 3, and an air inlet mesh hole 21 is provided above the heat dissipation box 14 to facilitate air intake and exhaust. An external snap 22 is hinged on each left and right side of the box cover 2, and each external snap 22 is snap-connected to an internal snap 23 fixed to the outer wall of the storage box 1. The mutually engaged external snaps 22 and internal snaps 23 facilitate the removal of the box cover 2 from the storage box 1.

[0029] Example 2

[0030] Based on Example 1, as a preferred embodiment of this embodiment, the bottom of the storage box 1 is connected to an extension box 12 below the heat dissipation box 14. The distance between the bottom of the extension box 12 and the top of the storage box 1 is greater than the length of the air supply plate 15. The top of the heat insulation board 16 is provided with a placement notch 160 for the air supply plate 15. The placement notch 160 can increase the stability of the air supply plate 15. The air supply pipe 150 is a flexible pipe. In this way, when the device is not in use, the air supply plate 15 can be placed inside the storage box 1 with the end connected to the air supply pipe 150 facing downward for easy storage.

[0031] As a preferred embodiment of the present invention, two legs 10 are symmetrically mounted on the left side of the bottom of the placement box 1, and the bottoms thereof are flush with the bottoms of the extension box 12. The legs 10 can make the entire device more flat when placed.

[0032] As a preferred feature of this embodiment, a heat conducting mesh 143 is installed between the two semiconductor cooling fins 142. The semiconductor cooling fins 142 can transfer the low temperature generated by them to the heat conducting mesh 143. Since metal has a much higher thermal conductivity than air, the heat conducting mesh 143 can quickly reduce the temperature of the air passing through it.

[0033] As a preferred embodiment of the present invention, a handle 24 is installed on the top of the box cover 2 to facilitate the movement of the device.

[0034] When the multi-stage heat dissipation battery box based on the energy storage system of the present invention is in use, the fins 11 can directly dissipate heat for the placement box 1 and the batteries 3 therein; the two semiconductor refrigeration plates 142 installed in the heat dissipation box 14 can cool the air passing therebetween, and send the air into the air supply plate 15 through the air supply pipe 150, so as to directly cool the batteries 3, thereby forming multi-stage cooling, which can keep the operating temperature of the batteries 3 at a low state; when the heat dissipation box 14 is in use, the heat dissipation blades 141 are driven to rotate by the motor to draw in the outside air from the air inlet mesh 21; the air drawn into the heat dissipation box 14 is cooled after passing through the two semiconductor refrigeration plates 142 and the heat conducting net 143 arranged therebetween, and is sent to the air supply plate 15 through the air supply pipe 150, and is sent between the two batteries 3 through the air outlet at the bottom of the air supply plate 15, so as to directly cool the batteries 3.

[0035] Finally, it should be noted that the motor and semiconductor refrigeration plate 142 in this embodiment are both existing conventional technical products, and are powered by the battery 3 when in use.

[0036] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
