Abstract: 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.

Abstract: An arrangement for cooling heat-generating built-in devices housed in plug-in units, wherein the plug-in units are arranged on top of each other in a component support or receiving housing, a cooling arrangement receives the coolant for the plug-in units to be cooled and returns the cooled coolant to the plug-in units, and the components of the cooling arrangement are housed in an insertion housing installed in the component support or receiving housing. Because of a simple attachment of damping elements to the insertion housing and their adjustment, an uncoupling with the plug-in units is achieved, so that sensitive built-in components of the plug-in units are no longer negatively affected by shocks and vibrations of the components of the cooling arrangement in the insertion housing.

Abstract: A refrigerating appliance having a refrigerant circulation device arranged in the housing of the appliance and including a compressor, an evaporator, and a condenser having an inner circuit and an outer circuit. The inner circuit is in communication with a region to be cooled, preferably the inner region of a control box, by a lateral wall of the appliance housing, an air inlet and an air outlet, the evaporator being associated with the inner circuit and the condenser of the refrigerant circulation device being associated with the outer circuit. According to this invention, all of the lateral walls, except the lateral wall comprising the air inlet and the air outlet of the appliance housing, are fully closed, and the condenser is formed as a base plate with integrated refrigerant lines. The base plate forms at least part of a lateral wall of the appliance housing. Refrigerating ribs protrude on the outer side thereof.

Abstract: 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.

Abstract: This sensor for measuring the flow velocity and/or the flow rate of a fluid provides an optical sensor system which is also suitable for use at temperatures higher than 400° C., does not come into contact with the fluid, and requires less space than conventional optical sensor systems. The sensor comprises a tube (1) through which the fluid flows in a first direction and which has a wall (11) in which a first window (2) and a second window (3) of optical, schlieren-free, high-temperature glass are set fluid-tight and pressure-tight at points lying opposite each other along a first tube diameter. A bluff body (4) is disposed along a second tube diameter and fixed in the tube for generating Kármán vortices, whose frequency f is proportional to the flow velocity u. The second diameter is up-stream of, and perpendicular to, the first.

Abstract: To achieve accuracies of the order of 0.75% of the measured value, a digitized, two-dimensional overall image of a bluff body (7), of the internal surface of a measuring tube (2) in the area of the bluff body, of the two fixing zones (71, 72) of the bluff body, and of contour line (51) of the inlet end (5) of the measuring tube is generated by a high-resolution electronic camera (9) located in front of the measuring tube (2) on the axis (3) of this tube. The overall image is divided into three partial images. The first partial image contains only information about the inlet end (5) and the internal surface (4) of the measuring tube, the second contains only information about the bluff body (7) without the fixing zones (71, 72), and the third contains only information about the fixing zones. From shape information about the fixing zones (71, 72) and ideal information characteristic of the ideal shapes of the fixing zones, cross-correlation information is formed.

Abstract: This device (1) produces a steep-fronted liquid pressure wave which strikes a body (12) to be tested with an adjustable table pressure. The device has a measuring tube (10) within or to which the body (12) is fixed, and which has a pressure-proof observation window (13, 14) and a pressure-relief valve (15). A pressure tube (20) with a compression system (25) which compresses a gas is closed on one side by a first diaphragm (29) which forms part of a chamber (27) that is provided with a valve (25). The chamber is closed by a second diaphragm (19) located opposite the diaphragm (29). In tube (10), a piston (18) is movable on guides (17) up to a braking device. To carry out the method, an amount of liquid which only partially fills the tube (10) is applied to the pistons In the chamber (27), a pressure equal to half the bursting strength of the diaphragms (29, 19) is set. The pressure in the tube (20) is increased until the bursting strength is exceeded.
