    Abstract: A heat exchanger arrangement includes walls defining at least two circuit passages for porting a first fluid, a first of the circuit passages defining a first passage length, and a second of the circuit passages defining a second passage length, the second passage length being different from the first passage length, the walls being in thermal communication with a second fluid while isolating the first fluid from the second fluid, at least one of the first circuit passage and the second circuit passage includes a flow control feature configured to decrease an imbalance in flow between the first circuit passage and the second circuit passage compared to if the flow control feature were not present.

    Abstract: An additively-manufactured heat exchanger includes fluidly-separated alternating first and second layers having respective flow channels which can include one or more features that is either a riblet or a turbulator. A riblet includes a riblet peak and/or a riblet valley, which has a riblet slope, and the riblet peak and/or riblet valley has a riblet axis that is generally parallel to either the first fluid flow direction or the second fluid flow direction. A turbulator includes a turbulator peak and/or a turbulator valley, which has a turbulator slope, and the turbulator peak and/or turbulator valley has a turbulator axis that is generally perpendicular to either the first fluid flow direction or the second fluid flow direction. The respective slope angles are generally 25-65 deg. relative to build-axis, thereby resulting in improved surface roughness and uniformity control during the build process.

    IPC: B41J2/44

    CPC classification number: B41J2/442

    Abstract: A micro cold spray printer system having: a printer housing having a longitudinal axis; a transfer tube defining an optical chamber oriented parallel and coaxial to a the longitudinal axis of the housing the optical chamber having an exit; a particle supply inlet fluidly connected to the optical chamber, the particle supply inlet in operation supplying particles to flow through the optical chamber along the longitudinal axis and out the exit; and a laser that in operation emits a laser beam into the optical chamber to heat the particles to a selected temperature. The laser beam is directed at an angle that is not parallel to the longitudinal axis.
