A cooling element for an electric component, in particular an electric battery of an electric or hybrid vehicle, includes: a pipe for a coolant, having two apertures at two ends of the pipe, and at least one secondary aperture. At least one external connecting pipe fluidically connects to the at least one secondary aperture. The external connecting pipe is connected to the secondary aperture through a quick-coupling.

A method of installing a drain water heat recovery exchanger for pre-heating water to be heated using a solar, electric or combustion energy hot water heater or to be sent to the cold-water line of a hot-water-consuming apparatus. It includes providing a drain water heat recovery exchanger including a copper pipe inlet fitting and a copper pipe outlet fitting and a core waste water drain tube, the fittings being fashioned to include barbs for a male plastic pipe connection; inserting the drain water heat recovery exchanger into a drain water pipe, wherein the core waste water drain tube is connected to the drain water pipe; and connecting a first one of the fittings to a cold-water supply and a second one of the fittings to an inlet of a hot water heater, a hot water tank or a cold-water line of a hot-water-consuming apparatus.

The manifold includes a column provided according to a longitudinal axis with a plurality of fluid outlet orifices spaced apart from each other. The column is removably mounted from a plurality of modular sections, each column section being provided with at least one female tubular axial fitting and/or with at least one male tubular axial fitting and featuring a radial opening delimiting the outlet orifice. Furthermore, a male tubular fitting is adapted to nest into and slide in a tight manner inside a female tubular fitting to enable a translational displacement of the sections relative to each other in directions of extension and retraction of the manifold in order to vary the spacing between two outlet orifices.

A cooling module for batteries of an electric or hybrid vehicle has a coolant supply line, a coolant discharge line, and a plurality of flat tubes arranged side by side, between which there is space for batteries to be cooled, each of the flat tubes being connected to the coolant supply line or the coolant discharge line. The flat tubes each carry connectors. The coolant supply line and the coolant discharge line are each assembled from a plurality of line segments connected by a connector of one of the flat tubes to one of the connectors of an adjacent flat tube. A spacer strip is arranged between adjacent flat tubes. The spacer strip delimits between itself and each of the two adjacent flat tubes spaces for batteries that are to be cooled.

A fresh air supply device for an internal combustion engine may include a suction module for conducting supercharged fresh air and a charge air cooler arranged in the suction module for cooling the supercharged fresh air. The suction module includes a housing with a charge air inlet for uncooled charge air and a charge air outlet for cooled charge air. The housing has a cooler shell, which may include the charge air inlet containing the charge air cooler and an assembly opening. With respect to a flow direction of the charge air the assembly opening may be arranged downstream of the charge air cooler and through which the charge air cooler is inserted into the cooler shell. The housing has a connecting shell, which includes the charge air outlet and which in the region of the assembly opening is attached to the cooler shell in an air-tight manner.

A pipe connector may include a lower motion link and an upper motion link, which may be fastened so as to be pivotable towards each other about a pivot axis. The lower motion link may have a lower seating for one of the pipe sections, and a bearing surface for the connection flange of the first pipe section. The upper motion link may have an upper seating for the other of the pipe sections, and a bearing surface for the connection flange of the second pipe section. The pivot axis may be aligned substantially at right angles to an axial direction of the lower seating and of the upper seating for the pipe sections. In a closed state, the bearing surfaces may be facing each other so that the connection flanges of both pipe sections may be able to be clasped.

Coupling devices (100) useful for fluidly connecting components of products, such as vehicle coolant components, are described. The coupling device may be press-fit onto male barb interfaces and thereby create a robust and durable liquid-tight seal, and may allow for autonomous factory installation. The coupling device may include an internal material (102), an external material (104), flared ends (106) connected by a cylindrical intermediary portion (108) and a hollow interior portion (110), wherein a hardness of the internal material is less than a hardness of the external material.

Unit (11) for feeding a reducing solution from the tank to the exhaust duct of an endothermic engine is provided. The unit comprises a supporting head (13) arranged for being associated to an aperture provided in a reducing solution tank and a heating device (15) for heating the reducing solution contained in the tank. The heating device (15) extends from the supporting head (13) and is provided with a duct (17) for a heating fluid. The duct (17) is defined by a side wall (31) which, when the unit (11) is in use, is internally in contact with the heating fluid passing through the duct (17) and externally in contact with the reducing solution present in the tank. At least one portion of the wall (31) of the duct (17) is non-smooth inside and/or outside the duct.
