Abstract: A method of additively manufacturing a component is provided. The method includes generating a three-dimensional (3D) model of the component, generating a first heat map of the 3D model which is illustrative of first thermal effects the component is expected to experience during additive manufacturing, generating a second heat map of the 3D model which is illustrative of second thermal effects the component is expected to experience during operational use, updating the 3D model to include 3D heat exchange fin models for reducing each of the first and second thermal effects and updating the 3D model with the 3D heat exchange fin models to include 3D weight reduction cavity models for weight-neutralizing the 3D heat exchange fin models.

Abstract: A cooling system and a wind power generating set. The cooling system comprises two cooling sub-systems thermally coupled to each other. Each cooling sub-system comprises: a first cooling circuit for cooling a first heat-generating component, a second cooling circuit for cooling a second heat-generating component, a third cooling circuit for cooling a third heat-generating component, a fourth cooling circuit for cooling a fourth heat-generating component, a pump station unit and a heat dissipation unit. The first cooling circuit and the fourth cooling circuit are connected in parallel to form a first branch, the second cooling circuit and the third cooling circuit are connected in parallel to form a second branch, and the first branch and the second branch are connected in parallel, and are connected to the pump station unit and the heat dissipation unit. The cooling system may achieve the fault-tolerant operation of two cooling sub-systems.

Abstract: A boss is provided around the periphery of a bushing that is penetrated by a shaft, which moves inside the bushing in the axial direction of the shaft. The boss retains the bushing and the shaft moving inside the bushing, and has a heat conductivity that is higher than that of the bushing. An air gap is provided between the bushing and the boss.

Abstract: A bearing housing for a turbocharger is disclosed. The bearing housing includes a first end proximate to a turbine wheel of the turbocharger and a second end proximate to a compressor wheel of the turbocharger. The bearing housing further includes a central chamber disposed between the first end and the second end and configured to house, at least, the shaft. The bearing housing further includes an oil drain disposed radially outward of the shaft and configured for directing oil out of the bearing housing and an oil core disposed radially outward of the shaft and radially inward of the oil drain, the oil core configured for communicating oil towards the oil drain and having an inner wall. The bearing housing includes one or more strakes protruding radially inward from the inner wall, the one or more strakes configured to direct oil within the oil core towards the oil drain.

Abstract: A bearing system comprises a bearing configured to be mounted to a shaft. A bearing housing interfaces the bearing to a structure. An annular gap is defined between an outer annular surface of the bearing housing and the structure and configured to receive oil therein. An outlet defined in an outer section surface of the bearing housing is oriented toward a component axially spaced from the bearing. A fluid passageway between the at least one outlet and the annular gap for fluid communication therebetween. In use the fluid passageway directs pressurized oil from the annular gap to the outlet to reach the adjacent component. A method for using oil from a bearing to cool or lubricate a component axially spaced from the bearing is also provided.
