Abstract
A rechargeable battery, in particular a rechargeable battery for a power tool, which includes a cell block having a sealing device provided for closing the cell block in at least a dust-proof and/or water-proof manner, and which includes an external rechargeable battery housing. It is provided that the external rechargeable battery housing is provided for conducting an airflow along between the external rechargeable battery housing and the sealing device.
Claims13
A rechargeable battery, comprising:
- a cell block having a sealing device to close the cell block at least in one of a dust-proof manner and a water-proof manner;
- an external rechargeable battery housing, wherein the external rechargeable battery housing is configured to conduct an airflow along between the external rechargeable battery housing and the sealing device;
- and
- a rechargeable battery cooling device to cool the cell block essentially independently of an airflow, wherein the rechargeable battery cooling device includes:
- at least one heat dissipating arrangement situated in the cell block configured for dissipating heat from the cell block, and
- a heat radiating arrangement configured for at least radiating the heat dissipated by the at least one heat dissipating arrangement,
- wherein, in at least one operating state of the rechargeable battery, the airflow is configured to exit at least through an opening of the external rechargeable battery housing through which a contact of a tool interface is contactable, wherein the tool interface is configured to establish a mechanical and an electrical connection with a power tool,
- wherein the sealing device has a sealing film which surrounds the cell block on at least one plane and lies against the cell block on at least four sides,
- wherein the at least one heat dissipating arrangement and the heat radiating arrangement are connected to one another by screws, wherein the screws press the at least one heat dissipating arrangement and the heat radiating arrangement from two different sides against the sealing film causing the at least one heat dissipating arrangement and the heat radiating arrangement to lie flush against the sealing film.
