The present invention concerns a heat-exchange element (31, 131) for a heat exchanger (1) enabling heat exchange between a first fluid and a second fluid, said heat-exchange element (31, 131) being designed to guide said first fluid through the inside of said heat-exchange element (31, 131) and said second fluid around the outside of said heat-exchange element, said heat-exchange element (31, 131) including at least one first duct (42, 43, 44, 45; 141, 142, 143) having a first essentially cylindrical wall and a second duct (42, 43, 44, 45; 141, 142, 143) having a second essentially cylindrical wall, the at least first and second ducts (42, 43, 44, 45; 141, 142, 143) being connected to one another by a portion of the first wall adjacent to a portion of the second wall.

A connector for connecting to tubes, in particular to the cooling plate tubes, including a body having a first tubular portion and a flange on the outer circumference and at one end of the first tubular portion. The connector includes two circular or tubular seals which are spaced apart and arranged on an inner peripheral surface of the first tubular portion, in which, the connector includes a leakage channel formed between a leakage opening and the flange, the leakage opening being disposed between the seals.

A high-voltage battery component includes a connection device for connecting a coolant line for a coolant to a heat sink of a high-voltage battery. The connection device has a connection part, which is connectable to the heat sink, and a sealing element arranged at the end of the connection part for providing a seal between the connection part and the heat sink. The connection device includes a spreading part, which is movable relative to the connection part. The spreading part, by pushing into the connection part, can be transferred from an insertion position for inserting the connection part into the heat sink into a sealing position. In the sealing position, the spreading part spreads the sealing element radially outward such that the sealing element can be placed in a sealing manner against the heat sink when the connection part is plugged into the heat sink.

Unit (11) for feeding a reducing solution from the tank to the exhaust duct of an endothemiic 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.

The invention relates to an indirect-type air cooler by way of which compressed charge air for an internal-combustion engine is cooled by means of a liquid, wherein the air cooler is constructed from stacked pairs of plates having fins which are disposed therebetween, and the brazed stack is disposed in a housing into which the charge air flows, flows through the fins and exits the housing again. The charge air exchanges heat with the liquid which flows in the plate pairs and which is introducible into the plate pairs via at least one inlet and via inlet-side plate openings which are flush in the stack and is dischargeable via at least one outlet by means of flush outlet-side plate openings. In order to further improve the performance potential of the air cooler, at least one venting element which extends to the exterior through an opening of the housing is connected to a liquid space within the stack.

A coupling device for a fluid cooling system may have a first coupling unit having a first housing, which has a first sub-housing and a second sub-housing connectable to the first sub-housing. The first sub-housing may have a first axial passage opening connectable to a first fluid line, a first signal interface and a first end face. The second sub-housing may have a second axial passage opening connectable to a second fluid line, a second signal interface and a second end face. The first sub-housing and the second sub-housing are axially connectable to one another and the passage openings are fluidically connected to one another and the signal interfaces are connected to one another. The two sub-housings may be laterally connectable to one another, so that in the laterally coupled state, the two sub-housings are arranged parallel next to one another.

A heat sink structure includes a plurality of radiation fins and a base. Each of the radiation fins has a connecting end and a free end, and internally defines a chamber extended between the connecting end and the free end for filling a working fluid therein. The base has an upper connecting surface provided with a plurality of connecting sections and a lower heat receiving surface in contact with a heat source. The connecting ends of the radiation fins are integrally connected to the connecting sections of the base in one-to-one correspondence through overmolding, so as to eliminate thermal resistance between the radiation fins and the base.

A plate heat exchanger and methods of construction and use which allow the plate assemblies used in the exchanger to be easily cleaned and maintained and which allow the plate assemblies to be individually and separately removed from the exchanger for cleaning or maintenance while the exchanger remains online and while the other plate assemblies in the plate heat exchanger continue to operate.

A water heater and a cover assembly for the water heater is provided. The water heater includes a mixing valve disposed in fluid communication with each of a hot water conduit and a cold water pipe, to regulate temperature of hot water received from the hot water conduit. The cold water pipe branches from a cold water conduit and extends along a longitudinal axis of the tank to connect with the mixing valve. The cover assembly is mounted on a tank of the water heater. The cover assembly includes a first cover to conceal the cold water pipe, and a second cover to conceal the mixing valve and the hot water conduit extending between the tank and the mixing valve. The second cover is removably coupled to the first cover via one or more coupling elements.
