Abstract: A wind turbine (10) includes a tower (12), a nacelle (14) cou- pled to the tower (12) and housing one or more heat generating components (18, 20), a rotor (16) having a least one wind turbine blade (24), and a cooler (38) mounted to the nacelle (14) and configured to cool the one or more heat generating components (18, 20) in the nacelle (14) by circulating a working fluid. The cooler (38) includes a support frame (46) coupled to the nacelle (14) and a heat exchanger (48) coupled to the support frame (46) and config- ured to cool the working fluid. The heat exchanger (48) includes at least two cooling panels (58) in non-planar relation with each other. The at least two cooling panels (50) may also be pivotably coupled to each other. A method of assembling a cooler (38) is also disclosed.

Abstract: A pipe coupling includes a pipe branch, a hose, and a retainer. The pipe branch forms a proximal branch section, a distal branch section, and an expanded section with an increased diameter therebetween. The hose includes an opening that receives the proximal branch section and includes a proximal fold, a distal fold, and a gasket therebetween. The gasket is arranged to seal between the hose and the proximal branch section. The retainer is configured to enclose the pipe branch and the hose and forms a proximal flange and a distal flange. The proximal flange and the distal flange both extend inwardly and define a passage for the pipe branch, the passage having a diameter which is smaller than the increased diameter. The proximal flange engages the proximal fold and the distal flange engages the distal branch section. The pipe coupling provides an easy and reliable connection between vibrating machine components.

Abstract: A pipe coupling comprising a pipe branch (2), a hose (3), and a retainer (4). The pipe branch forms a proximal branch section (5) terminating the pipe branch, a distal branch section (6) in extension to the proximal branch section, and an expanded section (7) with an increased diameter between the proximal branch section and the distal branch section. The hose terminating axially in an opening configured to receive the proximal branch section (5) in an axial direction and comprising a proximal fold (9), a distal fold (10), and an internal gasket (11) between the proximal fold and the distal fold, the gasket being arranged to seal between an inner surface of the hose and an outer surface of the proximal branch section. The retainer being configured to enclose the pipe branch and the hose and forming a proximal flange (12) and a distal flange (13), the proximal flange and the distal flange both extending inwardly and defining a passage for the pipe branch (2), the passage having an internal diameter which is smaller than the increased diameter, the proximal flange being configured for engaging the proximal fold and the distal flange being configured for engaging the distal branch section. The pipe coupling provides an easy and reliable connection e.g. between vibrating machine components or components which move relative to each other.
