Abstract
A diffuser for carrying air flow to an evaporator in an air conditioning system of an automotive vehicle includes an inlet and an outlet, a wall extending between the inlet and the outlet, and a guide vane, extending at least partially between the inlet and the outlet, spaced from the wall by a containing a control region whose area ratio changes along a length of the guide vane.
Claims16
A diffuser for carrying air flow to an evaporator in an air conditioning system of an automotive vehicle, comprising:
- an inlet;
- an outlet located downstream from the inlet;
- a wall extending between the inlet and the outlet;
- and
- a guide vane including a surface that extends at least partially between the inlet and the outlet, spaced from the wall by a gap containing a control region whose area ratio changes along a length of the guide vane, an inlet end and a second end located downstream from the inlet end.
A diffuser for carrying air flow to an evaporator in an air conditioning system of an automotive vehicle, comprising:
- an inlet;
- an outlet located downstream from the inlet;
- a wall extending between the inlet and the outlet;
- a first guide vane, extending at least partially between the inlet and the outlet, spaced from the wall by a first gap containing a first control region whose area ratio changes along a length of the first guide vane;
- and
- a second guide vane, extending at least partially between the inlet and the outlet, spaced from the first guide vane by second a gap containing a second control region whose area ratio changes along a length of the second guide vane.
A diffuser for carrying an air stream in an air conditioning system of an automotive vehicle, comprising:
- an inlet;
- an outlet located downstream from the inlet;
- a duct extending between the inlet and the outlet and including a side wall and a ceiling, whose surfaces are substantially locally saddle having a convex inward curvature in a direction transverse to the direction of air flow in the duct and concave inward curvature in the direction of an the air stream in the duct;
- and
- a guide vane located in the duct and extending at least partially between the inlet and the outlet, spaced from the side wall by a gap containing a control region whose area ratio changes along a length of the guide vane.
