Abstract

A heating or air conditioning system with a housing and with a heat exchanger located therein, wherein the housing constitutes an upper housing part and a lower housing part in which the heat exchanger is positioned, and the upper housing part forms, in the region where the heat exchanger is positioned, a housing wall that the heat exchanger is in direct contact with. The housing wall is designed to be elastic, at least in sections, such that the housing wall elastically yields in the contact region of the heat exchanger to compensate for dimensional tolerances of the heat exchanger.

Claims

1. A heating or air conditioning system comprising: a housing; and a heat exchanger arranged in the housing, wherein the housing has an upper housing part and a lower housing part in which the heat exchanger is positioned, wherein the upper housing part forms, in a region where the heat exchanger is arranged, a housing wall that the heat exchanger is in direct contact with, and wherein the housing wall is elastic, at least in sections, such that the housing wall elastically yields in a contact region of the heat exchanger to compensate for dimensional tolerances of the heat exchanger.

2. The heating or air conditioning system according to claim 1, wherein the housing wall forms, in the contact region of the heat exchanger, a seat region that is connected to the adjoining housing wall by at least one region of reduced wall thickness.

3. The heating or air conditioning system according to claim 2, wherein the seat region is essentially flat in design.

4. The heating or air conditioning system according to claim 2, wherein the seat region is a planar region that is surrounded, at least partially or completely, by the at least one region of reduced wall thickness.

5. The heating or air conditioning system according to claim 4, wherein the seat region is a planar region that is surrounded, at least partially or completely, by multiple regions of reduced wall thickness.

6. The heating or air conditioning system according to claim 2, wherein the region of reduced wall thickness connects the seat region to the adjoining housing wall in the manner of a bellows or a film hinge.

7. The heating or air conditioning system according to claim 2, wherein the seat region is offset relative to the adjoining housing wall in an unstressed state.

8. The heating or air conditioning system according to claim 2, wherein the seat region is displaceable relative to the adjoining housing wall in a direction substantially perpendicular to the plane of the seat region.

9. The heating or air conditioning system according to claim 7, wherein the seat region is preloaded in a direction toward an interior of the housing in the unstressed state.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein:

[0020] FIG. 1 is a schematic representation of a heating or air conditioning system according to an exemplary embodiment of the invention; and

[0021] FIG. 2 is, in a left-hand image, a schematic sectional view of a housing wall in the contact region of a first heat exchanger with a seat region, and in the right-hand image a second, somewhat larger heat exchanger with a seat region.

DETAILED DESCRIPTION

[0022] FIG. 1 shows a schematic representation of a heating or air conditioning system 1 with a housing 2 and with a heat exchanger 3 located in the housing 2. In this design, the heat exchanger 3 in the housing 2 is designed as an evaporator, and an additional heat exchanger 4 is also provided as a heater. The heating or air conditioning system 1 also has a fan 5 that draws in air and directs it into the air duct 6. Also provided in the air duct 6 is a filter 7 for filtering the air.

[0023] The housing 2 in this design has an upper housing part 8 and a lower housing part 9, wherein the heat exchanger 3 is positioned in the housing between the lower housing part 9 and the upper housing part 8. The upper housing part 8 forms, in the region where the heat exchanger 3 is positioned, a housing wall 10 that the heat exchanger 3 is in direct contact with.

[0024] The housing wall 10 can be designed to be elastic, at least in sections, such that the housing wall 10 elastically yields in the contact region 11 of the heat exchanger 3 to compensate for dimensional tolerances of the heat exchanger 3.

[0025] In this design, the housing wall 10 forms, in the contact region 11 of the heat exchanger 3, a seat region 12 that is connected to the adjoining housing wall 10 by at least one region of reduced wall thickness 13. This is shown in FIG. 2. The seat region 12 with which the heat exchanger 3 is in contact is connected to the adjacent housing wall 10 by the applicable region of reduced wall thickness 13.

[0026] It is also evident in FIG. 2 that the seat region 12 is essentially flat in design. Advantageously, the seat region 12 is a planar region that is at least partially or completely surrounded by the at least one region of reduced wall thickness 13. Preferably, the region of reduced wall thickness 13 surrounds the seat region 12 completely, for example in a rectangular or circular or oval shape.

[0027] It is also advantageous in this design when the seat region 12 is a planar region that is at least partially or completely surrounded by multiple regions of reduced wall thickness 13. In this way, the regions of reduced wall thickness 13 can permit a greater travel or displaceability of the seat region 12.

[0028] Thus, the region of reduced wall thickness 13 can connect the seat region 12 to the adjoining housing wall 10 in the manner of a bellows or a film hinge.

[0029] It is also advantageous when the seat region 12 is designed to be offset relative to the adjoining housing wall 10 in the unstressed state. This achieves the result that the seat region 12 is in contact with heat exchangers 3 even when they are small, whereas it is forced further outward in the case of larger heat exchangers 3. For this purpose, the seat region 12 is elastically connected or preloaded by the region of reduced wall thickness.

[0030] In the left-hand image, FIG. 2 shows a positioning of a somewhat smaller heat exchanger 3, in which the seat region 12 is in contact with the heat exchanger, wherein the seat region 12 is moved inward relative to the housing wall 10.

[0031] In the right-hand image, FIG. 2 shows a positioning of a somewhat larger heat exchanger 3, in which the seat region 12 is in contact with the heat exchanger, wherein the seat region 12 is moved somewhat further outward relative to the housing wall 10 than in the left-hand image.

[0032] FIG. 2 thus shows that the seat region 12 is displaceable relative to the adjoining housing wall 10 in a direction 14 perpendicular to the plane of the seat region 12.

[0033] It is also advantageous when the seat region 12 is preloaded toward the interior 15 of the housing 2 in the unstressed state.

[0034] The housing 2 and the housing wall 10 with the region of reduced wall thickness 13 and with the seat region 12 can be made of a plastic, such as, in particular, of polyamide, etc.

[0035] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
