1. A heat exchanger comprising:
a fins and tubes heat exchanger, comprising a stack of fins, the fins comprising at least one through hole coupled with a penetrating heat exchanging tube, and at least a portion of the fins comprising at least one through fluid aperture allowing fluid to pass from a first side of the fin to a second side of the fin;
a plates heat exchanger comprising a stack of plates, at least two sets of flow inlets and two sets of flow outlets, at least a portion of the plates each comprising a void and an embossment,
wherein each one of at least a portion of the fins of the fins and tubes heat exchanger being at least partially attached to or encompassed by a corresponding plate of the plates heat exchanger to define a set of a fin and a plate (SFP) such that fluid flowing over either side of the plate comes in contact with the fin;
wherein at least one of: (i) an alternating order of differently embossed plates; and (ii) an alternating orientation of plates in the stack, is adapted to enable one or more of (i) a simultaneous counter fluid flow, (ii) cross fluid flow or (iii) semi counter-cross fluid flow above and below the SFP; and
wherein the at least one through fluid aperture enables a sub-flow from a flow flowing over the fin to flow through the through hole and merge with a sub-flow flow flowing behind the fin in another direction.
