Abstract: The invention relates to a battery unit (1), particularly for a hybrid and/or electric motor vehicle, comprising a plurality of cells that are physically and/or electrically regrouped into a plurality of modules, a housing receiving and surrounding said cells, and means for regulating the temperature of said cells by circulation of a heat-transfer fluid. Said battery unit (1) is characterised in that the housing is made of a plastic material and consists of a lower tray (6), with a bottom and side walls, and an upper cover (7), which are peripherally assembled, and in that at least the tray (6) comprises means (5) for distribution/collection and circulation of the heat-transfer fluid, said means being structurally built into the body of said tray (6), by being formed at least partially as one piece therewith.

Abstract: A method for forming a hybrid heat exchanger is provided. The method includes laser-texturing a metal surface to create a plurality of microstructures and subsequently melt-bonding a plastic component to the plurality of microstructures. During melt-bonding, plastic material penetrates the plurality of microstructures and conforms to the plastic component to the metal surface. After hardening inside the microstructures, the plastic component adheres to the metal surface as a hybrid component. As a result, a fastener or snap connection is not required, and the plastic-metal joint provides a barrier to water, glycol-based fluids, air, and other fluids.

Abstract: Disclosed is an air intake manifold including a heat exchanger built into its body and including at least two ducts for supplying and removing heat-exchange liquid, the ducts extending through the wall of the body of the manifold with a liquid-tight seal and an airtight seal, which are distinct and mutually offset along the longitudinal axis of the relevant duct being created on each of the ducts. The unit creating the liquid tight seal is arranged between the relevant duct and a circulation pipe connected to the free end of the duct. The unit creating the airtight seal is positioned between the relevant duct and the body of the distributor. A leakage path associated with the liquid-tight seal is created between the latter and the airtight seal.

Abstract: A seal (1) is provided, in particular for a rotary ball valve fitting (2). The seal (1) has an annular body (4) that is resilient, flexible and provided with a radial lip (4?) and a rigid sealing ring (5) that are made in one piece. A valve, such as a rotary ball valve may include such a seal.
