Abstract: A fluid distribution tank of a heat exchanger includes a pair of plates, including a first plate and a second plate, coupled with each other to define a distribution chamber with a connecting opening between the first plate and the second plate, the connecting opening being adapted to form connection between the fluid distribution tank and a tubular element of the heat exchanger, and at least one dividing wall located between the first plate and the second plate to divide the distribution chamber into at least two sub-chambers. Volumes of the individual sub-chambers are different from each other.

Abstract: A tubular element for a heat exchanger, including: a primary tank with an inlet and outlet chambers, a secondary tank, a tube extending between the primary and secondary tanks, configured so as to provide U-flow for a fluid. The tube includes first and second separation walls with a separation space there-between. A dividing wall of the primary tank is in contact with the first and second separation walls. The inlet channels include a first inlet channel limited by the first separation wall and an inlet channel wall. The outlet channels include a first outlet channel limited by the second separation wall and an outlet channel wall. A distance between the first and second separation walls is smaller than a distance between the first separation wall and the inlet channel wall and is smaller than a distance between the second separation wall and the outlet channel wall.

Abstract: A tubular element for a heat exchanger, including: a primary tank with an inlet chamber and an outlet chamber for a heat exchange fluid, a secondary tank, a tube with inlet channels and outlet channels, configured so as to provide U-flow for the fluid within the tubular element. The primary tank includes a dividing wall between the inlet and outlet chambers. The tube includes a first separation wall and a second separation wall with a separation space there-between. The dividing wall is in contact with the first and second separation walls. The inlet channels include a first inlet channel limited by the first separation wall and an inlet channel wall. The outlet channels include a first outlet channel limited by the second separation wall and an outlet channel wall. The separation space includes a central arcuate structure adjacent the dividing wall.

Abstract: A tubular element for a heat exchanger includes at least one set of inlet channels, at least one set of outlet channels, and at least one separating wall configured between the at least one set of inlet channels and the at least one set of outlet channels. The at least one set of inlet channels and the at least one set of outlet channels are configured asymmetric with respect to each other with reference to the at least one separating wall.
