Patent attributes
The invention relates to an electric appliance (1) which comprises a machine module (2) provided with an electric machine (3) comprising a stator (4) and a rotor. A machine housing (7) of the machine module (2) receives the electric machine (3). A cooling module (19) comprises a cooling housing (21), which is fluidically connected to the machine housing (7) by means of a first cooling fluid connection area (20) in a housing wall (17) of the machine housing (7) and to at least one second cooling fluid connection area (23) in the housing wall (17) of the machine housing (7). The inside of the machine housing (7) can be fluidically connected to the inside of the cooling housing (21) in one section of the housing wall (17), which is oriented towards the cooling housing (21), by means of at least one third cooling fluid connection area (25) comprising at least one cooling fluid through-opening (26). Various cooling module variants can use said third cooling fluid connection area (25) when other cooling module variants, which can be used in exchange with the cooling module (19) in the machine module (2), do not use the third cooling fluid connection area (25). As a result, an electric appliance (1), a machine module (2) therefore and a set comprising a plurality of different cooling modules, which can meet altered cooling requirements having reduced structural and constructural costs, can be produced.
