Abstract
The invention relates to a motor vehicle passenger compartment heating, ventilation and/or air conditioning unit casing comprising at least: —an induction chamber (2) the peripheral wall of which forms a volute housing (12) and which is intended to accommodate an impeller of a motor-fan unit, —a distribution chamber (4) connected to an outlet (3) of the induction chamber (2), —distribution channels (5) connected to an outlet of the distribution chamber (4). According to the invention, the casing comprises an internal partition element (15) of which one face forms at least part of the volute housing (12) and of which the opposite face to the volute housing forms one wall of at least one distribution channel (5).
Claims14
A housing of a heating, ventilation and/or air-conditioning unit for a motor vehicle passenger compartment, the housing comprising:
- a suction chamber (2) having a peripheral wall forming a volute (12) and is intended to receive an impeller of a motor-fan unit;
- a distribution chamber (4) connected to an outlet (3) of the suction chamber (2);
- distribution channels (5) connected to an outlet of the distribution chamber (4);
- an internal partition element (15) having a face forming at least a portion of the volute (12) and a rear face opposite the volute forming a wall of at least one distribution channel (5);
- and
- two casings (10, 11) that together form an outer envelope of the housing with the internal partition element (15) inside and separate from the two casings (10, 11), wherein the two casings (10, 11) delimit at least another portion of the volute (12) of the suction chamber (2) and at least a portion of the distribution channels (5).
A housing of a heating, ventilation and/or air-conditioning unit for a motor vehicle passenger compartment, the housing comprising:
- a suction chamber (2) having a peripheral wall forming a volute (12) and is intended to receive an impeller of a motor-fan unit;
- a distribution chamber (4) connected to an outlet (3) of the suction chamber (2);
- distribution channels (5) connected to an outlet of the distribution chamber (4);
- and
- an internal partition element (15) having a face forming at least a portion of the volute (12) and a rear face opposite the volute forming a wall of at least one distribution channel (5);
- wherein a central portion (16) of the internal partition element (15) is bordered by two lateral wings (17), each extending on opposite side of a parting line (P) and terminating at a dividing wall (18), the dividing wall (18) extending in a direction perpendicular to the respective lateral wing (17), and with the parting line (P) extending in a direction perpendicular to an axis of rotation of the impeller when the impeller is received inside the suction chamber (2).
