Compact power supply device comprising cooling means

摘要

The device (10) has electrical energy storage units (20) arranged in a single case (32), and cooling units for cooling the storage units by convection. The cooling units produce flow of cooling air circulating in the case in a manner to scavenge the storage units. The case has units for increasing the speed of the cooling air flow during circulation of the airflow in the case from an upstream to a downstream. The case is arranged at level of the storage units to present a pipeline section decreasing from the upstream to the downstream, along a flow direction of the air flow.
