摘要： A heat exchanger includes a fluid flow passage with a wavy fin turbulizer. The turbulizer includes sidewalls extending lengthwise along a fluid flow direction between its first and second ends, and the sidewalls are spaced apart across the width of the turbulizer. Each flow channel of the turbulizer is defined between two adjacent sidewalls. Each sidewall has a smoothly and continuously curved profile with repeating wave forms being defined along the length of the turbulizer. The continuously curved profile of the sidewalls is defined by a non-circular shape, such as elliptical, sinusoidal, parabolic and hyperbolic shapes. The radius of curvature changes constantly and reaches a maximum at or near the inflection point between adjacent crests and troughs of the profile, to provide improved particle pass-through, lower pressure drop, and enhanced plateability of internal surfaces.

摘要： A two-pass heat exchanger with calibrated bypass is disclosed for cooling heat-generating substrates and/or for heating a heat transfer fluid. The heat exchanger has first and second outer plate walls and an intermediate plate wall located between and spaced from the outer plate walls in the thickness dimension of the heat exchanger, and with inlet and outlet ports at the same end. An input flow passage is defined between the first outer plate wall and the intermediate plate wall, and a return flow passage is defined between the second outer plate wall and the intermediate plate wall. The first and second fluid flow passages are in a U-flow, stacked arrangement. At least one bypass opening extends through the intermediate plate wall between the input and return flow passages, and configured to permit a portion of the heat transfer fluid to bypass portions of the input and return flow passages.

摘要： A modular heat exchanger for battery thermal management having a plurality of similarly constructed heat exchange elements affixed to a cover plate and fluidly coupled with one another via a single external manifold structure that functions as both an inlet manifold and an outlet manifold for each of the heat exchange elements. Rigidity is improved with alternating tabs or overlapping tabs between adjacent elements, and/or side edges between adjacent elements having cutouts for receiving stiffening ribs formed in the cover plate. The external manifold structure provides additional stiffening for the interconnected heat exchange elements.

摘要： A heat exchanger assembly includes a cooling plate with at least one outer heat transfer surface adapted for thermal contact with one or more heat-generating substrates. A fluid flow path extends from an inlet port to an outlet port, with a plurality of cooling zones spaced apart along the fluid flow path, each cooling zone including a heat transfer element such as a corrugated fin sheet in contact with the inner surface of the first plate wall. Manifold spaces are defined proximate to the inlet and outlet ports, and between adjacent cooling zones. One or more bypass flow passages are provided between upstream and downstream ends of at least one cooling zone, to divert a portion of the heat transfer fluid from flowing through the cooling zone. The volume of fluid flow bypassing one or more cooling zones is calibrated to improve temperature uniformity of the heat-generating substrates.

摘要： 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.
