Abstract: The invention relates to a condenser (1) which is exposed to air, having a ventilator (2) which conveys cooling air, is arranged in particular below condensation elements (4, 5) arranged in an A-shape, and presses intake cooling air into the triangular interior space (6) which is delimited by the ventilator (2) and the condensation elements (4, 5). Also provided are means for adiabatic cooling of the cooling air, wherein the means for adiabatic cooling are contact bodies (7) which can be placed in contact with water to be evaporated and which are arranged in the region of the cooling air flow (3).

Abstract: The invention relates to a power station comprising a condenser installation (2) for the condensation of water vapour, said condenser installation being mounted on a supporting structure (8) and comprising heat exchanger elements (5) past which cooling air flows from below. The condenser installation (2) is arranged in such a way that a longitudinal side thereof is directly adjacent to a building structure of the power station (1). A turbine house (3) comprises at least one wind passage (6) through which cooling air flows and/or is sucked beneath the heat exchanger elements (5).

Abstract: A condensation plant includes heat exchanger elements (10) which are mounted on a support structure (8) in particular in a roof-shaped manner and to which cooling air (K) is supplied via fans (11). The heat exchanger elements (10) are surrounded by a wind shielding wall (13), with the bottom edge (14) of the wind shielding wall (13) projecting further outwards than the top edge (15) of the wind shielding wall (13).

Abstract: A condensing system has a plurality of heat exchanger elements (2) which are disposed especially in a roof-shaped manner and to which cooling air (K) is fed via fans (3). An aerodynamic wall (7) is formed on a perimeter (5) of the condensation plant (1). Arranged on the perimeter (5) is a wind shielding wall (6) which is composed of plate elements (10). The plate elements (10) have a plurality of hollow chambers (9) which extend in a vertical direction. An air flow (L) can be introduced into at least some areas of the thus-configured wind shielding wall (6) in order to form an aerodynamic wall (7) above the wind shielding wall (6).

Abstract: Essentially triangular turbulators 3 extending at an angle .alpha. to the tube longitudinal plane RLE running through the tube axis RA as well as parallel to the fluid flow direction FSR are arranged on the flat lateral ribs 2 of a heat exchanger tube 1. The turbulators 3 are stamped out of the rib plane and are then bent off at an angle of approximately 90.degree.. They have flash or parting lines 4 rising in the fluid flow direction FSR as well as in the direction of the heat exchanger tube 1. This allows generation of longitudinal vortices 5 downstream of the turbulators 3 which roll over the boundary layers in this location and improve the heat transfer.

Abstract: A conveying installation with a linear motor drive including a stator placed along a travel path and at least one conveyor unit guided along the stator in a constrained manner. The stator is divided into a plurality of stator portions. To each stator portion is assigned a braking device whose operation is dependent upon the current supply to a stator. The conveyor units are guided spaced apart by a predetermined distance. If the current supply fails, the braking devices are actuated and stop the movements of the conveyor units.

Abstract: An electrical linear motor stator is fixedly disposed along a roadway. A car supported on at least two trucks is guided for movement along the roadway. The trucks are pivotally mounted to the car for rotation about a vertical axis. Permanent magnets for interacting with the stator have one end pivotally mounted to the vertical axis of the truck and an opposite end guided, for example, using rollers, for positive movement parallel to a vertical longitudinal central plane of the stator. In this way, the permanent magnet is mounted for transverse movement to the car to permit the car to negotiate small radius curves in the roadway while still maintaining good alignment between the permanent magnet and the stator.
