Abstract:
Disclosed are a battery and an unmanned aerial vehicle. The battery comprises a housing (1), a battery cell (2) and a cover body (3), wherein a heat dissipation air channel (11) is formed between the battery cell (2) and the housing (1); an air inlet (31) and an air outlet (32) which communicate with the heat dissipation air channel (11) are formed in the cover body (3); a first airflow channel (33) is provided in the cover body (3), and the first airflow channel (33) is bent and communicates with the air inlet (31) and the heat dissipation air channel (11); and/or a second airflow channel (35) is provided in the cover body (3), and the second airflow channel (35) is bent and communicates with the air outlet (32) and the heat dissipation air channel (11). The heat dissipation air channel communicating with the outside is formed in the battery, such that the working temperature of the battery can be reduced, the working efficiency and the performance of the battery can be improved, and the service life of the battery can be prolonged. Furthermore, the bent arrangement of the first airflow channel and the second airflow channel can achieve a waterproofing effect for the battery.
