Abstract

A housing for a ventilation, heating, and/or air conditioning system of a motor vehicle, wherein the housing is made of multiple parts and forms at least one air flow path in the interior and optionally has at least one heat exchanger, whereby the housing has first regions and has second regions, whereby the first regions have a greater strength than the second regions.

First claim

What is claimed is:

1. A housing for a ventilation, heating, and/or air conditioning system of a motor vehicle, the housing comprising:
multiple parts that form at least one air flow path in an interior;
at least one heat exchanger;
first wall regions;
second wall regions, the first wall regions having a greater strength and being subjected to greater mechanical stresses than the second wall regions; and
reinforcing components,
wherein the reinforcing components are directly fixedly attached only to the first wall regions,
wherein the reinforcing components are each formed by metal piece along with a film and/or a fabric piece, and
wherein along an exterior wall of the housing in an air flow direction, one of the second wall regions is positioned between two of the first wall regions, such that air flows past a first one of the two of the first wall regions, then past the one of the second wall regions and then past a second one of the two of the first wall regions.

2. The housing according to claim 1 , wherein the first wall regions have greater wall thicknesses than the second wall regions.

3. The housing according to claim 1 , wherein wall thicknesses of the second wall regions are more than 20% smaller than in the first wall regions.

4. The housing according to claim 1 , wherein the housing has a substantially uniform wall thickness.

5. The housing according to claim 1 , wherein the fabric piece is formed of carbon fibers and/or glass fibers and/or plastic fibers.

6. The housing according to claim 1 , wherein the housing is produced at least partially in an injection molding process.

7. The housing according to claim 1 , wherein the first wall regions and/or the second wall regions have concave and/or convex wall geometries.

8. The housing according to claim 1 , wherein the first and/or second wall regions have a substantially uniform wall thickness, which is reducible, and wherein the first and/or second wall regions are stiffened due to shaping, beading, pockets and/or complementary beading and/or pockets.

9. The housing according to claim 1 , wherein the housing, in a region of a neutral fiber, has a wall thickness smaller than a wall thickness in a region adjacent to the neutral fiber.

10. The housing according to claim 1 , wherein the first wall regions form bearing structures of the housing, and wherein the second wall regions form air-guiding structures of the housing.

11. The housing according to claim 10 , wherein the bearing structures are formed by aluminum die casting and/or magnesium die casting, and wherein the bearing structures are covered at least partially by the fabric piece and/or are overmolded with a thermoplastic and/or surrounded by the film.

12. The housing according to claim 1 , further comprising a supporting framework, the supporting framework being formed at least partially of profile elements.

13. The housing according to claim 1 , wherein wall thicknesses of the second wall regions are more than 60% smaller than in the first wall regions.

14. A housing for a ventilation, heating, and/or air conditioning system of a motor vehicle, the housing comprising:
at least one heat exchanger;
first housing regions, wherein the first housing regions comprising a metal portion for reinforcement; and
second housing regions, the first regions having a greater strength and being subjected to greater mechanical stresses than the second housing regions,
wherein the second housing regions include walls of an air channel and a partition wall provided inside the air channel, the walls of the air channel and the partition wall each being formed of a film or a fabric piece that is impermeable to air, such that an entirety of the partition wall is impermeable to air, and
wherein outer edges of the film or the fabric piece of each of the walls of the air channel being attached to profile elements that form an outer frame of the walls and outer edges of the film or the fabric piece of the partition wall being attached to profile elements that form an outer frame of the partition wall.

15. The housing according to claim 1 , wherein the reinforcing components are attached to an exterior surface of the first wall regions.

16. The housing according to claim 15 , wherein the reinforcing components are attached to the exterior surface of the first wall regions and to an interior surface of the first wall regions.
