A control cabinet arrangement, comprising a cooling device which is received in a control cabinet housing, wherein the cooling device can be slidably held on the control cabinet housing via a linear adjusting unit, particularly a bar system, and can be adjusted between a pull-out position and a slide-in position, wherein the cooling device in the slide-in position is completely received in the control cabinet housing, and in the pull-out position, the cooling device protrudes at least partially beyond a door side of the control cabinet housing from the control cabinet housing, and wherein a door element, which closes in its closed position the door side of the control cabinet housing, comprises at least one air passage opening which opens into an air outlet and/or an air inlet of the cooling device in the closed position of the door element, when the cooling device is in the slide-in position.

Electrical enclosure assembly comprising a cooling device which is received in an electrical enclosure housing

A cooling device, in particular for a switchgear cabinet with a housing, in which a refrigeration cycle system is housed, wherein the refrigeration cycle system has vibration-generating elements, namely a compressor and at least one fan. The fan and the compressor are supported in the housing via vibration dampers. For preventing vibratory emissions a cooling device in accordance with this invention has the fan and/or the compressor separately supported by first vibration dampers on an intermediate bracket, or together on an intermediate bracket. The intermediate bracket is supported by second vibration dampers on a bracket, and the bracket is connected to the housing.

Cooling device

A device for fixing and sealing a replaceable heat-exchanger cassette in an air/air heat exchanger, wherein two spatially separated conducting areas are formed by separating strips and the heat exchanger cassette. In this case a releasable and satisfactory sealing support of the heat exchanger cassette is achieved because in the area of its separating strips the air/air heat exchanger has sealing receivers. The heat exchanger cassette rests against the sealing receivers by sealing faces. The air/air heat exchanger has at least one movable slide which maintains the heat exchanger cassette in the sealing receivers under prestress.

Filter ventilator built in a HF-tight manner into a slot of a mounting

A filter ventilator for installation in an opening of a wall of a switchgear cabinet or the like, having a base housing receiving the filter, which is covered with a finned screen and which is connected with a ventilator on a side facing away from the finned screen. For a considerably simplified mounting of the filter ventilator, detent cams are molded on the base housing for fastening the ventilator. The detent cams engage bores in the facing flange of the ventilator. L-shaped holding elements are formed on the base housing which, facing the flange of the ventilator which faces away from the finned screen, have detent cams which engage bores of the flange. The L-shaped holding elements and the base housing form receivers, into which the ventilator, which is placed angularly offset on the base housing, can be rotated to a stop.

Switch cabinet cooling unit

An air conditioning or cooling device for a control cabinet with a spacer frame constructed of horizontal and vertical frames sections, each having fastening bores closed by wall panels and a door of the cabinet and being in the shape of a box. The air conditioning or cooling device is designed with its two exterior dimensions being equal to or less than two corresponding clearances between the vertical and horizontal frame sections of one side of the spacer frame and the air conditioning or cooling device is installed in this side. The installation of the air conditioning or cooling device on or in one side of the control cabinet in different positions, with respect to the interior of the control cabinet, is simply accomplished since the outer end area of at least its vertical sides with fastening edges, can be optionally connected directly or with spacing elements to the facing vertical frame sections of the spacer frame. The air conditioning or cooling device extends into the interior of the control cabinet if fastened directly and, if fastened with the spacing elements, terminates flush with the inner contours of the spacer frame.

Air conditioning or cooling device for a control cabinet

This invention relates to an air-water heat exchanger with an exchanger unit and a blower contained in a housing, which can be placed on the cover of a control box or the like and which is provided on the side facing the cover with an inlet and an outlet opening, which are aligned with corresponding openings in the cover of the control box or the like. By a particular routing of the air in the area of the inlet and outlet openings of the exchanger unit, even in case of leakage of the exchanger unit, no water can come out of the inlet and/or outlet openings and reach the control box or the like.

Air-water heat exchanger for a control box

This invention relates to an air conditioning device, particularly for a control panel, having a box-like lower housing part and a box-like cover which can be connected therewith. The air conditioning device can be installed on or in a mounting wall in accordance with this invention. For installation on a mounting wall, the bottom of the lower housing part and the mounting wall have connecting elements for attaching the lower housing part to the mounting wall. The lower housing part and the cover each have open sides directed towards one another and each have inwardly directed peripheral edges on the side walls. The edges of the lower housing part are turned towards the cover and have solidly attached threaded bolts. The edges of the cover have corresponding through-holes mateable with the threaded bolts. A peripheral sealing strip is inserted between the edges of the lower housing part and the cover. In an air conditioning device installed into a cut-away section of the mounting wall, between the edges of the lower housing part and the sealing strip, the mounting wall has mounting through-holes around the cut-away section. The mounting through-holes are mateable with the threaded bolts which are secured with nuts. The cover is connected with the lower housing part with mounting bolts, which are secured to the cover. The mounting bolts are axially adjustable to a limited degree and each has a threaded reception mount which is mateable with a threaded bolt.

Air conditioning device for a control panel

The invention relates to a cooling device having an evaporator, a blower with an outlet connecting piece, a condenser, and a compressor. A condensate collecting pan is positioned below the evaporator. The collected condensate water flows from the condensate collecting pan through a discharge pipe. In order for relatively large quantities of accumulating condensate water to be removed from the cooling device, the condensate water flows from the discharge pipe into a condensate collecting pan positioned below and downstream of an outlet connecting piece of the blower which discharges a warm air current. The warm air current of the blower flows to an outlet hole through an air channel which is connected to an outlet connecting piece of the blower.

Apparatus for removing condensate water from a compressor-operated

This invention concerns a control panel with an air conditioning device, in which the top of the body of the control panel and the bottom of the air conditioning device are connected to one another and provided with through openings adjusted and aligned to one another. In order for the air conditioning device to be rapidly and easily connected with the control panel, and likewise rapidly and easily removed, this invention provides an intermediary plate with through openings that is solidly connected with the top of the control panel. The through openings of the intermediary plate are adjusted and oriented to the through openings in the top of the body of the control panel. The intermediary plate has an upturned edge on three sides to form an accommodation for the air conditioner. For the detachable connection of the air conditioning device and the intermediary plate locking parts with at least one quick fastener each which are adjusted to one another are attached on the external sides of the edges lying opposite one another of the intermediary plate and the coordinated external sides of the air conditioning device. Insulating and sealing plates may be placed on the top and bottom of the intermediary plate and have corresponding through openings.
