Portable machine tool e.g. angle grinder, has housing unit partially surrounding drive unit and/or electronic unit, transport unit to transport thermal energy into housing unit, and cooling unit to cool drive unit and/or electronic unit

摘要

The tool has a drive unit (10) i.e. direct current motor, an electronic unit (12) and a housing unit (14) partially surrounding the drive unit and/or the electronic unit. A transport unit (16) is placed partly in the housing unit to transport thermal energy into the housing unit. A cooling unit (18) assures cooling of the drive unit and/or the electronic unit during the operation of the machine. The transport unit has a thermally-conductive element (20) to couple the drive unit for thermally coupling the drive unit and/or the electronic unit with the cooling unit.
