- the corridor is delimited by the external surface of revolution of the turbine, defined by the outer edge of the fins, and the inner face of the peripheral wall of the housing enveloping the blades of the turbine at a distance.
- the radial profile of the peripheral wall of the housing evolves in volute so as to gradually vary the separation distance between the edge of the fins and the inner face of the peripheral wall.
- the peripheral wall thus forms a spiral around the turbine in the direction, said spiral evolving in the direction of rotation of the turbine.
- volute To define the shape of the volute, we define an angle of expansion of the volute which corresponds, at a determined point of the volute, to the angle formed between the tangent to the volute and the tangent to a circle passing through this point , the center of the volute and said circle being constituted here by the axis of rotation of the turbine.

- FIG. 1 to 5 There is shown in Figures 1 to 5 a ventilation device 10 made in accordance with the teachings of the invention and intended to equip a heating, ventilation and / or air conditioning of a passenger compartment of a motor vehicle.
- the ventilation device 10 comprises a turbine 12 fin 13 rotatably mounted about an axis of rotation Al inside a casing 14 radially shaped volute.
- the housing 14 has an axial air inlet mouth 16 and a radial air outlet mouth 18 which communicate with the interior of a compartment 20, or corridor, volute delimited by the peripheral wall 22 of the housing 14
- the peripheral wall 22 of the housing 14 moves away radially and progressively from the periphery of the turbine 12 from a spout 24 of volute to a distal end E 2 of the volute, as shown in FIG.
- the spout 24 of volute which is shown in more detail in FIG. 3, consists of a portion of the peripheral wall 22 which is located generally at the intersection between the volute and a tubular outlet section 28 which extends from the distal end E 2 of the volute to the radial mouth 18.
- the distal end E 2 of the volute corresponds generally to the end of the radial expansion of the housing 14, the outlet section 28 extending in a generally correct way line in the direction of the air discharge Fl, in a direction generally tangent to the turbine 12.
- the volute has, at its spout 24, an initial expansion angle ai and at its distal end E 2 a final expansion angle a 2 .
- the value of the initial expansion angle ⁇ 1 is preferably between 1.5 and 3 times the value of the final expansion angle a 2 .
- the higher value of the initial expansion angle ai allows the volute to move radially away from the turbine 12 more rapidly at the beginning of its radial expansion than at the end of its radial expansion so as to minimize the turbulence produced. in the air flow at volute spout 24 which are the source of significant noise pollution given the close proximity of volute spout 24 with turbine 12.
- the expansion angle 3 ⁇ 4 increases gradually until it reaches its average value around the first third of the volute.
- the radial expansion of the volute is defined by the equation:
- R v i is the radius of the volute at a given point Ei of the volute
- R t is the outside radius of the turbine 12
- dtv is the minimum radial distance between the outer edge of the fins 13 of the turbine 12 and the spout 24 of volute
- 9i is the angle defined by the initial end Ei of the volute and the determined point Ei of the volute around the axis of rotation Al,
- ai is the initial expansion angle of the volute
- a 2 is the final expansion angle of the volute
- Omax is the volute angle that corresponds to the angle defined by the initial end Ei of the volute and the distal end E 2 of the volute around the axis of rotation Al.
- the volute angle 9 max thus defines the value of the angular sector along which the volute develops.
- the initial expansion angle ai of the volute is preferably between 3.5 and 9 degrees and the final expansion angle a 2 is preferably between 3 and 5 degrees.
- the volute angle ⁇ max is preferably between 290 and 315 degrees.
- Equation (1) defines the evolution of the radius R v i of the volute from the initial end Ei to the distal end E 2 . This equation has been developed to allow both an initial expansion angle ⁇ greater than the final expansion angle a 2 and a controlled progressiveness of radial expansion. The tests and measurements carried out by the applicant showed excellent results in terms of reduced sound level and in terms of efficiency of the pulsed air flow. Equation (1) provides a spiral profile for the volute which is particularly well suited for applications of the HVAC type for motor vehicles.
- the evolution of the axial expansion of the volute follows generally the evolution of the radial expansion of the volute.
- the evolution of the axial expansion can be dissociated from the evolution of the radial expansion, for example by increasing continuously and regularly all along the volute from its spout 24 to its distal end E2.
- the profile of the peripheral wall 22 of the casing 14 in an axial plane is curved to form a substantially oval or ellipsoidal portion intended to eliminate the angles inside the compartment 20.
- the axial section of the peripheral wall 22 possesses preferably a generally "C" shaped profile, as illustrated by the axial sectional view of FIG. 4.
- the volute thus has an upper inner circumferential edge 30 which is curved inwards and downwards and a circumferential edge lower internal 32 which is bent inwards and upwards.
- the upper circumferential edge 30 extends partially above the turbine 12, at the fins 13.
- the lower circumferential edge 32 is extended radially inwardly to form the bottom wall 36 of the housing 22, opposite the axial mouth 16.
- the radial outlet mouth 18 has an axial section of rounded or oval-shaped profile, as illustrated in FIGS. 1, 2 and 3, so that the outlet section gradually forms a tube.
- the spout 24 of volute has an oval profile, generally ellipsoidal or parabolic, which is illustrated in Figure 3, so as to minimize the turbulence produced in the air pulsed at the spout 24 of volute.
- the housing 22 according to the invention is particularly suitable for a turbine 12 whose outer profile, in an axial plane, is generally parallel to the axis A1, the outer edge of the fins 13 being generally vertical.
- the casing 14 is made in the form of two half-shells 38, 40 which are assembled with one another along a joint plane 42 orthogonal to the axis Al of the turbine 12, the joint plane 42 being illustrated in Figures 1 and 2.
- the two half-shells 38, 40 can thus be made by molding plastic material.
