Detailed Description
Batteries are typically provided with a control circuit board for managing the charging and discharging processes of the battery. Generally, the control circuit board generates heat seriously during the charging and discharging process of the battery. Traditional battery side is more than paying attention to the heat dissipation of electricity core, and lacks the heat dissipation design to control circuit board, and control circuit board's radiating effect is not good enough.
The embodiment of the application provides a battery module, can improve control circuit board's radiating effect. The following describes, by way of example, a battery module according to an embodiment of the present application with reference to the drawings.
Referring to fig. 1 to 6, a battery module 100 provided in an embodiment of the present application includes a battery cell 10, a case 20, and a control circuit board 30. The battery unit 10 and the control circuit board 30 are housed in the case 20. The control circuit board 30 is used for controlling the charging and discharging of the battery unit 10, and realizes the charging and discharging control of the battery unit 10.
The housing 20 includes a top cover 21. The outside of the top cover 21 is provided with a heat sink 211. The heat sink 211 serves to perform a heat dissipation function of taking away heat conducted to the top cover 21. The control circuit board 30 is located inside the top cover 21, and the control circuit board 30 is closely attached to the inner side surface of the top cover 21.
It should be understood that the inside of the top cover 21 refers to its side facing the inside of the housing 20, and correspondingly, the outside of the top cover 21 refers to its side facing the outside environment.
Because the control circuit board is tightly attached to the inner side of the top cover and the heat dissipation part is arranged on the outer side of the top cover, heat generated by the control circuit board can be conducted to the heat dissipation part through the top cover and taken away by the heat dissipation part. With the adoption of the method, the efficient heat dissipation of the control circuit board can be realized, and the safety performance of the battery module is improved.
In some embodiments, referring to fig. 1 and 2, the heat sink 211 is a heat sink fin group composed of a plurality of heat sink fins 211.
As one implementation, the group of heat dissipating fins may be formed on the outside of the top cover 21. In other words, the group of radiator fins may be a part of the top cover 21, integrally formed with the top cover 21.
As another implementation, the heat sink fin group may be a separate component from the top cover 21, and is mounted on the top cover 21 and closely attached to the outer surface of the top cover 21.
The heat dissipation fin group is arranged on the outer side of the top cover, so that the effective heat dissipation area can be remarkably increased, and heat conducted to the top cover can be timely taken away.
