Abstract: A heat exchange unit for heat pumps or air conditioners includes a box-like casing, a lower surface, an upper surface which is opposite the lower surface and which is spaced apart therefrom with respect to an axis of the casing, and a front surface which extends between the lower surface and the upper surface, the surfaces being defined on the casing. The heat exchange unit also includes a first opening and a second opening which are made on the casing, a channel which extends inside the casing between the first and second openings, a fan which is housed inside the casing, along the channel, and which is provided to move an air flow away from and towards the external environment with respect to the casing through the openings, and a heat exchanger which is placed in the channel, at least a portion of the fan and the heat exchanger being one below the other with respect to the axis.

Abstract: A heat exchanger device (13) comprising a tubular body (2) having an inlet opening (3) and an outlet opening (4) and defining within itself a first pathway (5) for a first liquid in a first prevalent direction of advance (6) from the inlet opening (3) to the outlet opening (4); a first connecting terminal (7) having at least a first inlet (8) for the first liquid and being sealedly couplable to the inlet opening (3) of the tubular body (2) and further couplable, at the first inlet (8) for the first liquid, to a first outlet pipe (9) for the first liquid; a second connecting terminal (10) having at least a first outlet (11) for the first liquid and being sealedly couplable to the outlet of the tubular body (2) and further couplable, at the first outlet (11) for the first liquid, to a second outlet pipe (12) for the first liquid; and an exchanger element (13) having an inlet (14) and an outlet (15) for a second liquid and defining within itself a second pathway (16) for the second liquid, the exchanger element
