A heat exchanger for thermal management of battery units made-up of plurality of battery cells or battery cell containers housing one or more battery cells. The heat exchanger has a main body portion defining at least one primary heat transfer surface for surface-to-surface contact with a corresponding surface of at least one of the battery cells or containers. A plurality of alternating first and second fluid flow passages are formed within the main body portion each defining a flow direction, the flow direction through the first fluid flow passages being generally opposite to the flow direction through the second fluid flow passages providing a counter-flow heat exchanger. In some embodiments the heat exchanger has two pairs of inlet and outlet manifolds, the heat exchanger providing a single-pass, counter-flow arrangement. In other embodiments the first and second fluid flow passages are interconnected by turn portions forming a U-flow, counter-flow heat exchanger.

Provided is a heat sink having excellent heat dissipation efficiency by having excellent thermal diffusion characteristics in a planar direction of a heat receiving plate.

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.
