As shown in fig. 1-3, in one embodiment of the present invention, a heat dissipation structure 100 for a battery pack is provided, which includes an inner frame 10, an outer frame 30, and at least two air supply modules 50.
The inner frame 10 has at least two battery module receiving cavities 11, each of the battery module receiving cavities 11 having an air inlet 12 and an air outlet 14, and a battery module 210 may be received in each of the battery module receiving cavities 11 of the inner frame 10 while allowing a cooling air flow to pass through the battery module 210 in the battery module receiving cavity 11 through the air inlet 12 and the air outlet 14. The outer shell 30 is sleeved outside the inner frame 10 at intervals, and an installation space is formed between the outer shell 30 and the inner frame 10; the at least two air supply modules 50 are respectively arranged in the installation space corresponding to the at least two battery module accommodating cavities 11, each air supply module 50 corresponds to one battery module accommodating cavity 11, and each air supply module 50 drives air to flow through the corresponding battery module accommodating cavity 11 so as to dissipate heat of the battery module 210 in the battery module accommodating cavity 11.
It should be noted that the battery module 210 may include a plurality of batteries, or may include only one battery. It should be noted that the description of the battery module 210 is only introduced for convenience of understanding, that is, the battery module 210 described in the following embodiments may be regarded as including only one battery without being inconsistent with the positions and functions of other elements.
Each air supply module 50 has an air guide space communicated with the air inlet 12 and/or the air outlet 14 in each battery module accommodating cavity 11, each air guide space is communicated with the corresponding battery module accommodating cavity 11 to form an independent heat dissipation air duct, so that the plurality of battery module accommodating cavities 11 are respectively communicated with the plurality of air guide spaces to form a plurality of independent heat dissipation air ducts, heat dissipation air flow in each independent heat dissipation air duct flows through the corresponding battery module 210, air flow in one independent heat dissipation air duct cannot flow into the other independent heat dissipation air duct to influence heat dissipation air speed, and uneven air volume and air speed around the plurality of battery modules 210 cannot be caused, so that the purpose of uniform heat dissipation is achieved.
For example, if the airflow in one air duct flows to the other air duct, the amount of air in the current air duct is reduced, the air speed is increased, and the heat dissipation is faster; the air volume in the other air channel is increased, the air speed is reduced, the heat dissipation is slow, and the heat dissipation of the two air channels is uneven. Therefore, the air flows in the air ducts flow independently, and after mutual interference is avoided, the air flows in each air duct keep the same air volume and air speed flow, so that heat of each battery module 210 can be uniformly dissipated, and uneven heat dissipation is avoided.
Specifically, each air supply module 50 includes an air guiding cover 54, each air guiding cover 54 corresponds to the air inlet 12 and/or the air outlet 14 in each battery module accommodating cavity 11 and is disposed between the outer shell 30 and the inner frame 10, and each air guiding cover 54, the outer shell 30 and the inner frame 10 jointly enclose an air guiding space communicated with the corresponding air inlet 12 and/or the air outlet 14, so that each air guiding cover 54 independently guides airflow to flow between the air guiding space and the corresponding battery module accommodating cavity 11 to form a plurality of independent heat dissipation channels to uniformly dissipate heat of the plurality of battery modules 210 in the plurality of battery module accommodating cavities 11.
Further, each air supply module 50 includes a fan 52, and each fan 52 is disposed in each air guiding space to drive airflow to flow in the corresponding independent heat dissipation air duct, so as to dissipate heat of the corresponding battery module 210.
The inner frame 10 has a partition plate 13, and the partition plate 13 is positioned between any two adjacent battery module receiving cavities 11 to block airflow between the two adjacent battery module receiving cavities 11. That is, any two adjacent battery module accommodating cavities 11 are separated into independent spaces by the partition plate 13, so that the air flows in the two adjacent battery module accommodating cavities 11 can flow independently, thereby avoiding mutual interference to influence the heat dissipation air quantity and the air speed, and achieving the effect of uniform heat dissipation.
In this embodiment, the inner frame 10 includes a plurality of sub-inner frames arranged side by side, each sub-inner frame has a battery module accommodating cavity 11, the side walls of two adjacent sub-inner frames contacting each other block the airflow passing through the partition plate 13, and each sub-inner frame has an air inlet 12 and an air outlet 14 distributed in a direction intersecting the side by side direction, and the air supply module 50 is arranged in the installation space corresponding to the air outlet 14.
