  • Patent number: 10923983
    Abstract: Generator housings for generators of aircraft are provided. The generator housings include a mounting pad at a first end, the generator housing extending to a second end, and a base arranged to connect to an electronics module. The generator housing defines a generator cavity and a flow path to supply a working fluid through the generator housing, the flow path extending between an inlet formed in the mounting pad and at least one outlet formed in the mounting pad. One or more electronics flow ports enable fluid connection between the flow path within the generator housing and the electronic module when connected and one or more inductor ports enable fluid connection between the flow path within the generator housing and one or more inductors when mounted to the generator housing.

  • Patent number: 10415903
    Abstract: A fluid cooled cold plate includes a main coolant passage with a first cross-sectional area taken laterally in a direction perpendicular to the flow direction and a finned coolant passage having a second cross-sectional area taken laterally in a direction perpendicular to the flow direction, with the second area smaller than the first area. Fluidly connecting the main coolant passage with the finned coolant passage is a branch oriented such that a fluid is turned 90° or more when passing into the branch from the main coolant passage. Also included is a coolant bypass passage in fluid communication with the main coolant passage and located fluidically parallel to the finned coolant passage.
