Abstract
(EN)
The utility model provides a battery box which comprises a lower box body, and the lower box body comprises a first plate and a second plate, the peripheral wall is connected to the periphery of the bottom wall and extends upwards, and the bottom wall and the peripheral wall form a containing space with an upward opening in the height direction; the second plate is fixed to the bottom wall from the lower portion and connected with the bottom wall to form a liquid inlet flow path, a liquid outlet flow path and a main flow path communicating with the liquid inlet flow path and the liquid outletflow path. The main flow path comprises a first main flow path body, a second main flow path body and a plurality of parallel branch flow path bodies communicating with the first main flow path body and the second main flow path body. According to the battery box disclosed by the utility model, the first plate and the second plate are jointed to form the lower box body and form the heat exchange flow path, and the box body and the heat exchange flow path are integrated into a whole, so that the overall weight is reduced; in addition, due to the external design of the heat exchange flow path, the influence of liquid leakage of the heat exchange flow path on a battery in the battery box is effectively avoided; furthermore, a main flow path formed by jointing the first plate and the second plate is short in heat exchange path and uniform in heat exchange, and the heat exchange effect is improved.
