  • Patent number: 11002487
    Abstract: A counter flow heat exchanger: has an inner container with radially outwardly projecting helical webs, a cylindrical housing, wherein an inner circumferential surface of the housing and the radially outer edges of the helical webs of the inner container are in contact such that a flow path is developed in which a first heat transfer fluid can flow between the helical webs of the inner container and the inner circumferential surface of the housing; a helical heat exchanger tube extending between the helical webs of the inner container such that a second heat transfer fluid can flow within this heat exchanger tube counter to the direction of flow of the first heat transfer fluid. A method for the production of a counter flow heat exchanger is also provided.

  • Patent number: 9647251
    Abstract: A device for cooling batteries includes a cooling plate for receiving at least one battery thereon and at least one heat transfer element in heat transfer relationship with the cooling plate. A mechanical stress produced by a contact force causes the at least one heat transfer element to thermally abut the cooling plate.

  • Patent number: 8551632
    Abstract: A battery cooling system includes a battery and a plurality of battery cooler pipes disposed adjacent the battery. Each of the battery cooler pipes is spaced apart and substantially parallel to an adjacent one of the battery cooler pipes. A clamping element is disposed adjacent at least one of the battery cooler pipes. The clamping element configured to urge the battery cooler pipes against at least a portion of the battery. The clamping element includes a plurality of clamping wings extending outwardly from a center portion of the clamping element. Each of the clamping wings of the clamping element is disposed adjacent at least one of the battery cooler pipes. The battery cooling system may further include a carrier disposed adjacent the center portion of the clamping element to absorb spring forces of the clamping wings.
