Abstract
A charger includes a charger housing with at least one battery-charging space accessible from the outside for positioning of a rechargeable battery unit, a charging electronics unit in the charger housing for controlling an electrical charging operation for the battery unit positioned on the battery-charging space, and a cooling-air-guiding structure configured for guiding a cooling-air flow from an air inlet structure of the charger housing via the charging electronics unit to an air outlet structure of the charger housing. The cooling-air-guiding structure has a cooling housing arranged in the interior of the charger housing and has a cooling housing air inlet structure and a cooling housing air outlet structure, and is configured for guiding the cooling-air flow through the cooling housing from the cooling housing air inlet structure to the cooling housing air outlet structure and from the latter to the air outlet structure of the charger housing. The charging electronics unit has at least one electronic component which is arranged in the cooling housing. Use may be for electrically charging rechargeable battery packs for electrically operated garden and forestry working apparatus.
