  • Publication number: 20210071919
    Abstract: A heat exchanger system includes a heat exchanger device, which has elastocaloric elements made of elastocaloric material and is designed to move the elastocaloric elements, as a result of which said elements are deformed, so that an elastocaloric effect is achieved. The heat exchanger system further includes a vibrating unit, which generates mechanical vibrations, and a vibration transfer device arranged between the vibrating unit and the heat exchanger device, and which transfers the vibrations from the vibrating unit into the elastocaloric elements so that the elastocaloric elements move.

  • Patent number: 9995154
    Abstract: A method for producing a component, in particular a rotor wheel, includes positioning a main body, a fusion-weldable attachment layer, and a barrier layer. The main body has a first alloy in an attachment region. The fusion-weldable attachment layer is positioned in the attachment region of the main body and has a second alloy which differs from the first alloy. The barrier layer is positioned between the main body and the fusion-weldable attachment layer. The barrier layer is configured to prevent a reaction of the first alloy of the main body with the second alloy of the fusion-weldable attachment layer during a thermal treatment. The method further includes heating the main body, the barrier layer, and the fusion-weldable attachment layer to connect the main body, the barrier layer, and the fusion-weldable attachment layer to one another.

  • Publication number: 20150196971
    Abstract: A turbine wheel includes, a hub body, a plurality of turbine blades integrally formed with the hub body, and a shroud. The shroud encompasses the hub body, is integrally formed with the turbine blades, and interconnects the respective radial outer edges of the turbine blades. A method of producing the turbine wheel in one piece via primary forming includes applying a layer of powdered material having a predetermined layer thickness to a construction platform, selectively melting the layer of powdered material with reference to a current layer form of the turbine wheel, moving the construction platform by a predetermined amount, and repeating applying, selective melting, and moving until a last layer of the turbine wheel is formed.

  • Publication number: 20150125306
    Abstract: A method for producing a connection of at least one rotary component with a central opening to a shaft with a first section along the shaft and a second section on an end face of the shaft includes fixing the shaft at the first section in the central opening of the at least one rotary component by an eccentric arrangement. The fixing of the shaft is such that the shaft is fixed in the radial direction relative to the at least one rotary component. The method also includes fixing the shaft at the second section by press-fitting a ball so that the shaft is secured in the axial direction relative to the at least one rotary component. The fixing steps are carried about by a positive engagement.

  • Publication number: 20140072404
    Abstract: A turbine wheel for a continuous-flow machine includes a centrally arranged hub with circumferentially arranged blades and a pressure equalizing channel. The hub is configured to enclose a cavity, and a resulting principle axis of inertia of the turbine wheel coincides with an axis of rotation of the turbine wheel. The pressure equalizing channel is configured to fluidically connect the cavity to at least one axial end face of the hub and to an environment of the turbine wheel. A diameter of the pressure equalizing channel is smaller than a diameter of the cavity. In one embodiment, the turbine wheel is for an exhaust gas turbocharger.
