Abstract

A power-tool cooling apparatus for a portable power tool includes a first fan configured to generate a first cooling fluid flow to cool a drive unit of the portable power tool, and a second fan that generates a further cooling fluid flow to cool an electronics unit of the portable power-tool. A third fan generates a third cooling fluid flow to cool a second electronics unit of the power-tool, and supplies cooling fluid to the first cooling fluid flow.
