A control cabinet with a frame having framing profiles and covered with side members and at least one door. The frame surrounds the inside of the control cabinet where electrical components are integrated. An air conditioning device which is placed on at least one vertical side of the frame rejects heat generated inside the control cabinet. This invention provides this type of cooling apparatus with additional equipment without the need for a large number of pieces. For this purpose, a separating member, parallel to the lateral side and placed at a distance therefrom, is attached to the framing profiles and forms with the side channel an air guiding channel. Moreover, the separating member comprises several passages for providing a physical connection between the air guiding channel and the inside of the control cabinet. Furthermore, air can be conveyed through the air guiding channel and through at least one passage by using at least one fan.

Control cabinet with cooling device

A control cabinet having a cabinet body with opened sides which can be closed at least partially by one or more side walls. An air conditioning device which is placed near at least one side wall rejects heat generated inside the cabinet body or guides it towards the inside of the cabinet body. This invention simplifies the design of the air conditioning device. For this purpose, an intermediate wall which is parallel to the side wall and located at a distance therefrom, is placed in such a way that it is oriented towards the inside of the cabinet body. In addition, the air conditioning device is placed in the intermediate space surrounded by the side wall and the intermediate wall.

Control cabinet

A control cabinet with an air conditioning device mounted inside the control cabinet and physically connected to the inside of the control cabinet via an air condution channel. The inside of the control channel is surrounded by side walls and at least one door. This invention provides efficient air conditioning inside the cabinet. For this purpose, an intermediate wall is placed at a distance from the side wall and an air collecting channel created between the side wall and the intermediate wall is physically connected to the air conduction channel of the air conditioning device through input openings and to the inside of the control cabinet through at least one passage.

A switch cupboard with devices for cooling the hot air present inside the same. At least one vertical face is closed off by a double-walled wall element whose outer and inner wall panel form an air duct with an extensive surface. The inner wall panel has several openings spread out from each other. The openings can be covered either with cover plates, fans which operate in two directions of rotation or connecting plates with sections of hose.

A fan with an input mounting plane and an output mounting plane. The fan is adapted to be mounted on a control cabinet wall member with an aeration passage. This invention produces an air flow which is as dust-free and turbulence-free as possible. For this purpose, the input mounting plane and the output mounting plane form an acute angle.

An improvement to the lock elements of a filter ventilator that is engaged in an opening in a fastening plate in such a manner that a housing part with an outer cross section that corresponds to the cross section of the opening includes a stop flange that limits insertion of a filter on the fastening plate and lock elements arranged on the outside of the housing part wherein the spring-like elements each have a free end attached to the housing part such that the free end is oriented toward a support surface on the rear side of the stop flange, the ends of the lock elements include a plurality of lock stages oriented in a stepped arrangement so as to form a locating section substantially perpendicular to the support surface and a lock section that is substantially parallel to the support surface where the lock sections include spaces of equal width and the locating sections are sized for varying thicknesses of fastening plates, and the lock stage nearest the support surface includes a space with respect to the center axis of the filter ventilator that is the same as or greater than the smallest corresponding dimension of opening in the fastening plate.

The invention relates to a wall air conditioning apparatus for a control panel, with a fan and a lamellar heat exchanger, featuring a box-like housing with an upper inlet opening and a lower outlet opening in the wall that faces the control panel, whereby the fan is arranged behind the inlet opening and the lamellar heat exchanger is arranged under the fan and over the outlet opening at an acute angle to this wall. For improved ventilation and drainage of condensation water, it is provided that the lamellae of the lamellar heat exchanger are at an acute angle to the floor of the housing and drop off toward the wall that faces away from the control cabinet, and that the floor of the housing is provided with a drain for condensate.
