An electrical room housing electrical and electronic apparatus for operating and controlling electrical motors of an industrial equipment is disclosed. The electrical room includes a cooling device with a first heat exchanger which is arranged with a first set of channels through which is conducted a first flow of air drawn from inside the electrical room. Warm air from inside the electrical room is circulated through the first heat exchanger of the cooling device and returned to the electrical room in a closed loop, and the air temperature in the electrical room is controlled dependent on a setpoint of between 24-40° C. A method for controlling the cooling device to cool the electrical room and one or more computer programs arranged for controlling the cooling device are also described.

Cables of round cross section, e.g., circular or ovate, and a cable bus housing assembly therefor are disclosed wherein the housing assembly is based essentially on similar panels which may be connected together into two opposed series of end-to-end connected panels. Normally, a plurality of cables are received between the panels with the opposed series secured together to cause substantial contact of concave surfaces of the panels with the peripheral surfaces of the cables. The housing assembly is designed especially for conducting heat out of the enclosed electrical conductors and dissipating the heat to the surrounding atmosphere by radiation and convection.

A power distribution box is disclosed. The power distribution box includes one or more continuous-powered receptacles and a plurality of power-alternating receptacles. The continuous-powered receptacle is in a constant energized state during operation of the power distribution box. At least one of the plurality of power-alternating receptacles is in a de-energized state during operation of the power distribution box at any instance while at least one of the plurality of power-alternating receptacles is in an energized state at any instance. The power distribution box disclosed herein allows for electronic devices that should remain constantly on to be electrically coupled to the one or more continuous-powered receptacles, and for electronic devices that don't require constant power to be electrically coupled to the plurality of power-alternating receptacles in order to control power consumption and prevent electrical overload.

A light emitting apparatus includes a light source, a unitary formed heat sink with a plurality of heat dissipating fins, a lensed enclosure that retains a light source and at least one power consuming device other than the light source. The lensed enclosure includes a recessed opening having at least a first wall that terminates at a substantially perpendicular second wall. The plurality of heat dissipating fins are disposed on at least one adjacent exterior side of the walled enclosure, the fins extending outwardly. At least one fin coupled to the heat sink extends beyond the light source, and the heat generated by the light source travels by conduction laterally through the heat sink to the at least one coupled fin.

摘要:
A line arrangement comprising an electrical line which has at least one electrical insulator and at least one electrical conductor which runs at least in some sections adjacently to the electrical insulator along a longitudinal axis of the electrical line. The line arrangement additionally has a passive heat dissipator which runs at least in some sections along the longitudinal axis and which has at least one heat-absorbing surface portion and at least one heat-emitting surface portion thermally connected to the heat-absorbing surface portion. The heat-absorbing surface portion is brought towards the electrical conductor at least to such an extent that the heat-absorbing surface portion forms a thermally operative connection to the electrical conductor in order to dissipate waste heat from the electrical conductor to the heat-emitting surface portion.
