Definitions
- the third section comprises at least one third lover aligned at a third louver angle measured with respect to the intended first fluid flow direction.
- the third louver angle is substantially equal to the first louver angle.
- a heat exchanger 1 enables the heat exchange between two fluids, wherein one fluid (e.g. refrigerant) is encapsulated and circulates within the heat exchanger 1 and the other fluid (e.g. air) usually flows across the sub-components of the heat exchanger 1.
- one fluid e.g. refrigerant
- the other fluid e.g. air
- standard fin 50 location reduces the packaging in front of tubes 40, with respect to intended first fluid flow direction.
- This also applies to other heat exchangers such as evaporators.
- evaporators it is desired to facilitate the evacuation of condensate created in the phase change process of the first fluid.
- the fin 50 being lined up with the first terminal end 50a with the first lateral walls 40a and protruding with the second terminal end 50b of the second lateral wall 40b of the stack being arranged as a last one with respect to intended first fluid flow direction is made of one piece.
- the fins 50 may also be delimited perpendicularly to the stacking direction S1 by inner faces of the header-tank assemblies 20,30.
- the fin 50 may be configured to at least partially deflect the first fluid flow path.
- deflect should be understood as to cause (the air) to change its direction with respect to its intended fluid flow path.
- the second section 200 may receive the first fluid both in gaseous and liquid form.
- the second section 200 is configured to separate two phases of the first fluid, so that the liquid is evacuated from the vicinity of the tubes as quickly, as possible. Therefore, the second section 200 may also be called evacuation section.
- the heat exchanger 1 may comprise a gap T3 located between the first stack 41 and the second stack 42. It is evident from Fig.3 that the gap T3 is smaller than any of the thickness T1 or T2, however, an embodiments in which the gap T3 is greater than the first thickness, second thickness T2 or both first and second thickness T1, T2 is also envisaged.
- At least one of the louver angles may be in particular 35 degrees.
- the orientation and the location of the second section allow to facilitate evacuation of liquid first fluid form the heat exchanger, so that the efficiency of the second stack 42 is improved.
