A control-cabinet system has a base module and at least one functional module. The base module has a base housing with a first housing face and a second housing face. The functional module has a functional housing with a housing underside, where a circulation channel is arranged. Air flow may be circulated in the circulation channel, where each base connection element comprises circulation openings which are fluidically connected to the circulation channel. The functional connection element comprises coupling openings fluidically connected to an interior of the functional housing. The coupling openings are coupleable to the circulation openings, in which a fluidic connection exists between the circulation channel and the interior of the functional housing. A fluidically closed circulation circuit comprising the circulation channel and the interior of the functional housing is formed, in which air flow may be circulated.

A controller assembly includes a plurality of controller units, and a heat dissipating unit interposed between the controller units. Male and female connectors are disposed in the controller units, and the connectors thereof are fitted to female and male connectors of the heat dissipating unit to thereby establish electrical contact therebetween. Upon driving electric actuators, heat generated in circuit boards of the controller units is dissipated to the exterior through a plurality of heat dissipating protrusions provided on the heat dissipating unit, so that heat generating sources of the circuit boards are cooled.

A heat sink for use with a heat generating component such as an electronic power module comprises a first substrate having a serpentine slot, a second substrate secured to a first side of the first substrate to form a combined substrate, surfaces of the first and second substrates at least partially forming a serpentine passageway within the combined substrate for containing a fluid. The serpentine passageway has a non-circular cross-sectional shape.

A motor drive device includes a case including a first surface and a housing portion that opens to the first surface side, a terminal block including a terminal to which an electric wire extending to an outside of the case is connectable and being housed in the housing portion, an openable and closable cover covering the opening, and a lock unit restricting opening and closing of the cover and bringing the cover into a locked state in a state where the cover is closed. The lock unit is provided on the cover to be rotatable about an axis perpendicular to the first surface in a state where the cover is closed. An unlocked state in which the cover is openable and the locked state are switched according to rotation angle of the lock unit. The lock unit includes a state indicator indicating that the cover is in the locked state.
