Definitions
- Heat exchange module comprising a fan nozzle and a heat exchanger, in particular for a motor vehicle
- the invention relates to heat exchangers, in particular for motor vehicles.
- It relates more particularly to a heat exchange module comprising a fan nozzle assembled with a heat exchanger with two manifolds.
- the fan nozzle is equipped with one or more motor-fan groups to channel a flow of air capable of sweeping the body or bundle of the heat exchanger.
- the fan nozzle is provided with lugs which are fixed to the manifolds of the heat exchanger by means of screws or the like. These are usually self-tapping screws introduced into studs or bosses specially fitted on the manifolds of the heat exchanger.
- Such an assembly constitutes a long operation and can be compatible with the high rates of assembly or assembly lines in the automotive industry.
- the main object of the invention is to overcome such a drawback.
- the fan nozzle comprises at least two studs which extend from a first side of the nozzle and which are suitable for engage in corresponding housings of a first header of the heat exchanger box, and 'at least two elastic snap-on lugs which extend from a second side of the nozzle of this fan in a direction opposite to the studs, said lugs each being provided with an opening suitable for delivering passage to an ergct projecting from a side face of a second manifold of the heat exchanger.
- each latching tab depends on a stirrup which is attached to the second side of the fan nozzle and which provides an opening capable of being crossed by a pin secured to a wall end of the manifold, so that the assembly of the fan nozzle on the heat exchanger includes a final introduction phase in which the studs penetrate into the housings and simultaneously the pins penetrate into the openings of the stirrups .
- each bracket comprises a bridge in which the opening is formed, and to which the latching tab is attached, as well as two branches connecting the bridge to the second side of the fan nozzle, in so that, during the final phase of the introduction, the snap-on tab first deviates laterally under the action of the lug then approaches, letting the lug penetrate into the opening of the tab d 'snap.
- each lug comprises a sloping wall, forming a ramp, to facilitate the spacing of the latching tab.
- the use of b fan comprises two tabs latching spaced, one of which is capable of providing a positioning reference and the other to compensate a dispersion between the second box collector and fan nozzle.
- the housings of the first manifold are each formed by a U-shaped bracket.
- the fan nozzle comprises three spaced apart pads suitable for respectively engaging in three housings of the first manifold.
- the fan nozzle as well as its studs and its latching lugs are made in one piece by molding a plastic material.
- first manifold and its housings are made in one piece by molding a plastic material.
- second manifold and its lugs are advantageously made in one piece by molding a plastic material.
- the first manifold and the second manifold are provided to extend horizontally, respectively in the lower part and in the upper part of the heat exchanger.
- the heat exchanger constitutes a radiator for cooling a motor vehicle engine.
- L F i ⁇ ure 1 is a partial perspective view of a module n s elo view the invention comprising a nozzle on this fan assembly a heat exchanger;
- Figure 2 is a partial perspective view of the fan nozzle of the module of Figure 1;
- FIG 3 is a partial perspective view of the heat exchanger forming part of the module of Figure 1;
- Figure 4 is a vertical sectional view of the module of Figure 1.
- the module shown in FIGS. 1 and 4 comprises a heat exchanger 10, here consisting of a radiator for cooling a motor vehicle engine, on which a fan nozzle 12 is assembled.
- the heat exchanger 10 comprises a body or bundle 14 formed of vertical tubes (not shown) and connected respectively to a first manifold box 16 and to a second manifold box 18. These two manifolds are generally horizontal in direction and are provided for be placed respectively in the lower part and in the upper part of the heat exchanger.
- the latter comprises an inlet pipe 20 and an outlet pipe 22 (FIG. 1) respectively serving for the admission and the evacuation of a liquid passing through the heat exchanger, in the example a coolant d 'a motor vehicle engine.
- a liquid passing through the heat exchanger in the example a coolant d 'a motor vehicle engine.
- this liquid flows through the heat exchanger in a downward vertical direction.
- the manifolds 16 and 18 are produced by molding a plastic material, for example of the polypropylene type.
- the fan nozzle 12 comprises (FIG. 1) a bottom plate 24 of generally rectangular shape which is provided for s' eten dr parallel and vis-à-vis a large face 26 (f i g ure 4) of the body 14 of the heat exchanger.
- This bottom plate e maynag a circular opening 28 ( Figure 1) for the oger a motor fan unit (not shown) comprising an electric motor driving a propeller.
- the group motor-venti the creator is supported by an open structure 30 attached to a circular cylindrical wall 32 attached to the bottom plate 24.
- the assembly formed by the bottom plate 24, the open structure 30 and the cylindrical wall 32 is made in one piece by molding a plastic material, in particular of the polypropylene type, to constitute the fan nozzle as a whole.
- This fan nozzle is designed to be assembled with the heat exchanger, so that the motor-fan unit can force a flow of air, by blowing or by suction, and that this flow is channeled to sweep the body 14 of the heat exchanger and cool the liquid which flows through this heat exchanger.
- the fan nozzle 12 comprises, in the lower part, three studs 34 (only two of which are visible in FIG. 1). These studs extend from a first side 36 (lower horizontal side) of the nozzle 12 and are directed vertically downwards. These studs thus extend substantially in the plane defined by the bottom plate 24 of the nozzle 12.
- a central stud is advantageously provided framed by two lateral studs, these studs having come from molding with the fan nozzle 12.
- a fan duct 12 further comprises two lugs detent 42 ( Figures 1, 2 and 4) of which only one is visible in Figure 1. The two legs are connected both to a second side 44 (upper side horizontal) of the nozzle 12, so as to extend opposite the studs 34.
- Each of the legs 42 depends on a bracket 46 which is attached to the second side 44 of the fan nozzle. More particularly, this stirrup 46 comprises a bridge 48 to which the latching tab is attached, as well as two parallel branches 50 connecting the bridge 48 to the side 44 of the fan nozzle. These branches 50 extend in the extension of the bottom plate 24 of the nozzle.
- the bridge 48 constitutes a generally rectangular plate which extends in a plane substantially perpendicular to that of the bottom plate 24 and which is provided with an opening 70.
- the tab 42 is an elastic tab which has an end 52 connected to the bridge 48 and a curved end 54 directed towards the side 44 of the nozzle and which extends parallel to this side.
- the tab 42 is capable of moving apart elastically while struggling inside the housing 56 which is delimited between the two parallel branches 50.
- This tab 42 has an internal opening 58 suitable for delivering passage to a lug 60 ( Figures 1, 3 and 4) projecting from a lateral face 62 of the manifold 18.
- a lug 60 ( Figures 1, 3 and 4) projecting from a lateral face 62 of the manifold 18.
- Each lug 60 comprises a sloping wall 64 forming a ramp.
- each lug 60 Near each lug 60 is provided a pin 66 ( Figures 1, 3 and 4) which extends from an end face '68 of the manifold 18, this end wall being substantially perpendicular to the side wall 62 on which the lug 60 depends.
- the latching lugs 42 and the corresponding stirrups 46 have come from molding with the fan nozzle 12. From even, the pins 60 and the pins 66 came from molding with the manifold 18.
- the snap tabs 42 are not necessarily strictly identical. Thus, it is advantageous that one of these tabs is capable of ensuring a positioning reference and that the other is capable of catching up with a dispersion between the manifold 18 and the fan nozzle 12.
