Abstract
Abstract A mounting device for a heat exchanger in the housing of an air conditioning and/or ventilation apparatus. A heat exchanger element comprises means for its being hooked to the casing so that the simple introduction of the exchanger in the housing provides at the end of the movement the fixation of the exchanger which is hooked to the casing. The invention is particularly applicable to air conditioning apparatuses for the passenger space of a motor vehicle.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
63 words
A device for mounting and fixing a heat exchanger in a casing of a ventilation apparatus for an automotive vehicle, said heat exchanger having a water box at one end, wherein said water box is formed with resilient lugs adapted to cooperate by hooking with stationary parts of the casing at the end of the introduction of the heat exchanger inside the casing.
Claim 2
Independent Claim
63 words
A device for mounting and fixing a heat exchanger in a casing of a ventilation apparatus for an automotive vehicle, said heat exchanger having a water box at one end, wherein said water box is formed with resilient lugs adapted to cooperate by hooking with stationary parts of the casing at the end of the introduction of the heat exchanger inside the casing.
Claim 3
Dependent Claim
30 words
A device as claimed in claim 1, wherein the casing comprises, on one of its faces, an opening through which is introduced the exchanger, in the manner of a drawer.
Claim 4
Dependent Claim
32 words
A device as claimed in claim 1, wherein the water box is made of a plastic material and the resilient lugs form an integral unit with a cover of said water box.
Claim 5
Dependent Claim
42 words
A device as claimed in claim 3, wherein the water box cover has a rectangular cross section and comprises four hooking resilient lugs near the apexes of the water box cover and at the ends of the longer sides of said cover.
Claim 6
Dependent Claim
30 words
A device as claimed in claim 4, wherein the hooking lugs are positioned at some lateral distance from the cover edges and are connected to the cover via marginal sections.
Claim 7
Dependent Claim
58 words
A device as claimed in claim 5, wherein an introduction opening of the casing is bounded by a protruding edge adapted for cooperating by abutment with the said marginal sections of the resilient lugs and the casing further comprises up-turned edges spaced away from the protruding edge for cooperating by hooking with the ends of the resilient lugs.
Claim 8
Dependent Claim
34 words
A device as claimed in claim 6, wherein the tightness is provided by a resiliently compressible band pressed between the protruding edge of the casing and a marginal section of the water box cover.
Claim 9
Dependent Claim
22 words
A device as claimed in claim 1, wherein the hooking lugs are formed with a plurality of shoulders distributed over their length.
Claim 10
Dependent Claim
24 words
A device as claimed in claim 1, wherein the hooking lugs are flexible at their fixation portion, providing the immobilization by a snapped-in engagement.
Claim 11
Dependent Claim
25 words
A device as claimed in claim 1, wherein a resiliently compressible band completes the tightness between the water box and the edges of the casing.
Claim 12
Dependent Claim
22 words
A device as claimed in claim 10, wherein the band is pressed between an edge of the casing and the water box.
Claim 13
Dependent Claim
52 words
A device according to claim 1, wherein the heat exchanger comprises another water box opposite to that provided with said resilient hooking lugs, said another water box being housed in a well of the casing and resilient sealing bands being interposed between the another water box and the walls of the well.
Claim 14
Dependent Claim
91 words
A mounting and fixation device for a heat exchanger in a casing or housing of an air conditioning and/or ventilation device of the passenger space of a motor vehicle, wherein one element of the heat exchanger comprises means for its hooking into the casing so that by the simple introduction of the exchanger inside the casing, there is obtained at the end of the movement the fixation of the exchanger which is hooked to the casing, said means comprising a hook formed with a plurality of shoulders distributed over its length.
Claim 15
Dependent Claim
91 words
A mounting and fixation device for a heat exchanger in a casing or housing of an air conditioning and/or ventilation device of the passenger space of a motor vehicle, wherein one element of the heat exchanger comprises means for its hooking into the casing so that by the simple introduction of the exchanger inside the casing, there is obtained at the end of the movement the fixation of the exchanger which is hooked to the casing, said means comprising a hook formed with a plurality of shoulders distributed over its length.
