Patent number: 11190084Abstract: An electric machine (14, 16) for a drive train (12) of a motor vehicle (10) has a coil arrangement and a rotor mounted rotatably relative to the coil arrangement. A fluid line is connected thermally to at least one component of the electric machine (14,16) to supply a cooling fluid (36) to the electric machine (14, 16) and to cool the at least one component. A fan (30, 32) is designed to supply cooling air (42) to the electric machine for cooling the electric machine (14, 16), and a control unit (34) controls the fan (30, 32). The control unit (34) controls the fan arrangement (30, 32) and the cooling air supply depending on a speed (n) and/or a torque (M) of the electric machine (14, 16).Type: GrantFiled: June 10, 2015Date of Patent: November 30, 2021Inventors: Werner Schiek, Leo Spiegel, Holger Hinrich

Patent number: 10381896Abstract: A cooling device for a vehicle, having an inner housing with an inner cooling wall, and an outer housing which surrounds the inner housing, is spaced apart via a cooling gap and has an outer cooling wall. A cooling volume for passage of a cooling fluid is formed between the inner cooling wall and the outer cooling wall. The inner cooling wall and/or the outer cooling wall furthermore have channel walls for dividing the cooling volume and guiding the cooling fluid. At least one clamping device is arranged around the circumference of a circumferential wall of the outer housing for introducing a deformation force into the outer housing in order to reduce the cooling gap by deforming the outer housing.Type: GrantFiled: November 16, 2017Date of Patent: August 13, 2019Assignee: Dr. Ing. h.c. F. Porsche AktiengesellschaftInventor: Holger Hinrich

Patent number: 9636994Abstract: A cooling device (2) is provided for a hybrid module (1) of a hybrid vehicle. The hybrid module (1) has an actuator arranged between an internal combustion engine and an electric drive unit of the hybrid vehicle for actuating a separating clutch for separating the internal combustion engine and the electric drive unit. The hybrid module (1) also has control electronics (7). The actuator and the control electronics (7) are arranged within a heat protection hood (9) and at least the control electronics (7) are connected to the heat protection hood (9). The heat protection hood (9) is composed of heat-conducting material and is connected to a housing part (5) of the hybrid module (1). The cooling device enables use of the hybrid module in the region of hot components, such as the internal combustion engine or an exhaust system.Type: GrantFiled: January 29, 2015Date of Patent: May 2, 2017Assignee: Dr. Ing. h.c.F.
