A gas/liquid heat exchanger comprises a stack of flat tubes, defining liquid flow passages. Spaces between the flat tubes define gas flow passages, with the sides of the core having an irregular comb-like arrangement. The heat exchanger further comprises a housing having side covers over the sides of the core, and being spaced from the sides of the core. The core has at least one portion of reduced width, so as to provide channels extending throughout the height of the core. The heat exchanger further comprises a pair of side seals at least partly received in the gap between the side cover of the housing and the core, and more particularly in the channels along the sides of the core. The side seal extends throughout the height of the core and has a thickness which is greater than that of the gap.

The invention relates to valve system configurations for an active warm-up (AWU) system for an automobile to improve warm-up conditions without delaying cabin warm-up or defrost times. More specifically, the invention relates to a system for heating/cooling transmission fluid of an automobile by controlling the source of the heat exchange fluid for transferring heat to/from the transmission fluid during different start-up conditions using a series of various valves arranged in series intermediate a first heat exchanger associated with cabin warm-up/defrost of the passenger compartment and a second heat exchanger for transferring heat to/from the transmission fluid.

A heat transfer surface and a heat exchanger comprising the heat transfer surface are disclosed, the heat transfer surface comprising a corrugated member having parallel spaced apart ridges and planar fin surfaces extending therebetween. The planar fins surfaces comprise tabs formed in the surface thereof for forming counter-rotating vortices in the fluid flowing over the heat transfer surface, the tabs being lifted out of the surface of the planar fin surface and extending into or nesting within the openings formed by the corresponding tabs in the adjacent planar fin surface so as to achieve high fin density.

A plate and frame style heat exchanger is disclosed herein the heat exchanger is formed by a plurality of heat exchange plates and frame members that are alternatingly stacked together to form fluid channel members. The frame members are formed by lengths of material that are formed or bent into the desired configuration for providing a first fluid tight seal around the periphery of the plates and a second fluid tight seal around respective fluid openings formed in the heat exchanger plates in order to achieve the desired flow configuration through the heat exchanger. In some embodiments the frame members are made up of two mating frame portions that join together in a self-aligning and self-fixturing relationship to facilitate assembly.

A heat exchanger for cooling battery cell containers in a battery unit is disclosed. The heat exchanger includes individual heat exchanger modules that are fluidly interconnected and spaced apart from each other so as to accommodate individual battery cell containers arranged between adjacent heat exchanger modules to form a battery unit. Each heat exchanger module is formed by a pair generally planar first and second heat exchanger plates having a main section and flexible inlet and outlet panels extending therefrom. The heat exchanger is formed by a stack of alternating first and second plates that are brazed together to form heat exchanger modules, the heat exchanger modules formed in the stack being interconnected by their inlet and outlet panels and expanded post-brazing by bending/flexing the inlet and outlet panels to provide adequate spacing or gaps between the modules to accommodate battery cell containers.
