Abstract

The servomotor and reduction gear are housed in a casing and drive a movable shutter in an air vent. The servomechanism involves a temp. sensor in the passanger compartment, a linear potentiometer and an electronic circuit connected by a cable to the motor. Channels convey a fraction of the fresh air flow into the appts. towards the inlet of the electrical system's cooling circuit, and then around the electronic circuit package and into the motorised fan assembly. Air entering the fan housing circulates within the space around the fan so as to dissipate heat from the fan motor armature. The fan blades create a sufficient drop of pressure within the housing to draw fresh air through the cooling circuit.

Description

La présente invention concerne un appareil de chauffage et de climatisation, en particulier pour un véhicule, du type connu suivant : cet appareil comporte un organe de réglage, tel qu'un volet mobile, dont un servo-mécanisme asservit la position à la grandeur de sortie d'au moins un capteur thermométrique, placé par exemple dans la cabine du véhicule. The present invention relates to a heating and air conditioning device, in particular for a vehicle, of the following known type: this device comprises an adjustment member, such as a movable flap, of which a servo-mechanism controls the position to the size of output of at least one temperature sensor, for example placed in the vehicle cabin.

Un tel appareil de chauffage et de climatisation est généralement constitué par un ensemble extrêmement compact de conduits d'air, dans lequel sont intégrés les différents composants du servomécanisme, de façon que les cotes extérieures de l'appareil soient les plus réduites possible, compte tenu de la place limitée qui est disponible sous le capot du véhicule. Comme certains des conduits d'air sont traversés par un flux d'air chaud, il est à craindre que les composants mentionnés soient portés à des températures nuisibles non seulement à leur bon fonctionnement mais aussi à leur durée de vie, et cela d'autant plus que ces mêmes composants sont générateurs de chaleur. Such a heating and air conditioning device is generally constituted by an extremely compact set of air ducts, in which the various components of the servomechanism are integrated, so that the external dimensions of the device are as small as possible, taking into account limited space available under the hood of the vehicle. As some of the air ducts are traversed by a flow of hot air, it is to be feared that the components mentioned will be brought to temperatures which are harmful not only to their proper functioning but also to their service life, and all the more so. more than these same components are generating heat.

L'objet principal de la présente invention est de perfectionner l'appareil de chauffage et de climatisation qui vient entre indiqué, de façon à améliorer les conditions thermiques de fonctionnement des différents composants de son servo-mécanisme, afin de leur conférer des caractéristiques de fonctionnement parfaitement stables et une longue durée de vie. The main object of the present invention is to improve the heating and air conditioning apparatus which comes between indicated, so as to improve the thermal operating conditions of the various components of its servo-mechanism, in order to give them operating characteristics. perfectly stable and long life.

L'appareil de chauffage et de climatisation selon la présente invention est du type indiqué, et il est caractérisé en ce que des conduits y sont aménagés pour faire circuler de l'air extérieur, à proximité de certains au moins des composants du servo-mécanisme. The heating and air conditioning device according to the present invention is of the type indicated, and it is characterized in that conduits are arranged there to circulate outside air, near at least some of the components of the servo-mechanism. .

A titre d'exemple, on a décrit cidessous et illustré schématiquement au dessin annexé une forme de réalisation de l'appareil de chauffage et de climatisation selon la présente invention. By way of example, an embodiment of the heating and air conditioning apparatus according to the present invention has been described below and illustrated diagrammatically in the accompanying drawing.

Les figures 1 et 2 sont des vues de cette forme de réalisation, en coupe partielle par deux plans sensiblement perpendiculaires l'un à l'autre.  Figures 1 and 2 are views of this embodiment, in partial section through two planes substantially perpendicular to each other.

La figure 3 est une vue en élévation dans le sens de la flèche III de la figure 2;
Sur les figures du dessin annexé, 1 désigne un servo-moteur-réducteur, qui est logé dans un bottier 2, dont les dimensions intérieures sont un peu supérieures à celles du carter dudit servo moteur-réducteur 1.Ce dernier comporte un axe de sortie, la (figure 2), qui est accouplé mécaniquement à l'axe de commande, 3a, d'un volet mobile 3, par exemple un volet pivotant; ce volet pivotant est monté de façon à contrôler le canal intérieur d'une conduite traversée par un flux d'air; comme visible sur la figure 2, l'axe de commande 3a traverse, de façon sensiblement étanche, la paroi 4 de cette conduite d'air * Le servo-mécanisme de commande de la position du volet mobile comporte en outre un capteur thermométrique, par exemple une thermistance (non représentée), placée par exemple dans la cabine du véhicule, un potentiomètre, par exemple rectiligne, 5, et un circuit électronique 6; le potentiomêtre 5 et le circuit électronique 6 sont logés dans un mEme bottier fermé 7, qui est accolé au bottier 2 du servo-moteur l,le long de sa cloison 2a; le curseur 5a du potentiomètre rectiligne 5 est accouplé, par exemple à une tirette (non représentée) montée au tableau de bord du véhicule, par exemple par l'intermédiaire d'une transmission à cible souple.Figure 3 is an elevational view in the direction of arrow III of Figure 2;
In the figures of the appended drawing, 1 designates a servo-motor-reducer, which is housed in a case 2, the internal dimensions of which are slightly greater than those of the casing of said servo-motor-reducer 1. The latter has an output axis , the (Figure 2), which is mechanically coupled to the control shaft, 3a, of a movable flap 3, for example a pivoting flap; this pivoting flap is mounted so as to control the inner channel of a pipe through which an air flow passes; as can be seen in FIG. 2, the control axis 3a crosses, in a substantially sealed manner, the wall 4 of this air duct * The servo-mechanism for controlling the position of the movable flap further comprises a thermometric sensor, by example a thermistor (not shown), placed for example in the vehicle cabin, a potentiometer, for example rectilinear, 5, and an electronic circuit 6; the potentiometer 5 and the electronic circuit 6 are housed in the same closed case 7, which is attached to the case 2 of the servo-motor l, along its partition 2a; the cursor 5a of the straight potentiometer 5 is coupled, for example to a pull tab (not shown) mounted on the dashboard of the vehicle, for example by means of a flexible target transmission.

Par ailleurs, les différents composants électriques ou électroniques 1, 5 et 6 sont interconnectés électri quementyde façon connue en soiXpar un faisceau de conducteurs C (figure 2) de façon à cbnstituer un dispositif d'asservissement de la position du volet mobile à la grandeur de sortie du capteur thermométrique.Furthermore, the various electrical or electronic components 1, 5 and 6 are electrically interconnected in a manner known per se X by a bundle of conductors C (FIG. 2) so as to create a device for controlling the position of the movable flap to the magnitude of output from the temperature sensor.

Selon la présente invention, des conduits sont aménagés pour faire circuler de ltair, non seulement autour du carter du servo-moteur 1, c'està-dire entre ce carter et les parois du bottier 2, mais aussi au contact de l'une au moins des parois du bottier 7 où sont logés le potentiomètre 5 et le circuit électronique 6; ce dernier conduit a été désigné par 8, tandis que, sur la figure 1, 9 désigne un conduit transversal, qui fait communiquer le conduit 8 avec l'intérieur du bottier 2 du servo-moteur 1. 10 dO- signe la tubulure d'entrée da circuit de refroidisse- ment des composants électriques 1, 5 et 6, tandis que 11 désigne sa tubulure de sortie. According to the present invention, conduits are arranged to circulate air, not only around the casing of the servomotor 1, that is to say between this casing and the walls of the shoemaker 2, but also in contact with one at less of the walls of the case 7 where the potentiometer 5 and the electronic circuit 6 are housed; this latter conduit has been designated by 8, while, in FIG. 1, 9 denotes a transverse conduit, which communicates the conduit 8 with the interior of the boot 2 of the servo-motor 1. 10 dO- signs the manifold input of the cooling circuit of the electrical components 1, 5 and 6, while 11 designates its outlet pipe.

Une fraction du flux d'air extérieur qui pénètre dans 1'appareil de chauffage et de clina- tisation considéré, par une tubulure appropriée 12 (figure 3), est dérivée par une conduite 13, en amont du volet mobile 3, vers la tubulure d'entrée 10 du circuit de refroidissement des composants 1, 5 et 6; ce flux d'air frais circule dans le bottier 2 autour du carter du serso-moteur 1, comme indiqué par différentes flèches sur les figures 1 et 2; le même flux d'air est ensuite amené, par le conduit 9, dans le conduit 8, où il circule au contact de certaines des parois du bottier 7 où sont logés le potentiomè- tre 5 et le circuit électronique 6; l'air qui ainsi refroidit les composants électriques 1, 5 et 6, passe ensuite, par l'intermédiaire de la tubulure de sortie 11, dans une conduite 14 (figures 1 et 2), qui l'amène à la tubulure d'entrée, 15, du bottier,16, du groupe moto-ventilateur, 17, de l'appareil; comme on l'a indiqué sur la figure 2, par des flèches, l'air amené dans le bottier 16 par la tubulure d'entrée 15, y circule dans l'intervalle aménagé entre la paroi dudit bottier 16 et le groupe moto-ventilateur 17, de façon à refroidir ce dernier et aussi l'intérieur de ce groupe 17, notamment l'induit du moteur Slectrique ss c'est bien entendu la turbine 17a du ventilateur qui crée dans le bolier 16 une dépression suffisante pour aspirer l'air extérieur à travers le circuit de refroidissement 13- 10-9-8-11-14-15. A fraction of the external air flow which enters the heating and air conditioning device under consideration, by an appropriate tube 12 (FIG. 3), is diverted by a pipe 13, upstream of the movable flap 3, towards the tube. input 10 of the cooling circuit of components 1, 5 and 6; this flow of fresh air circulates in the case 2 around the crankcase of the crankcase 1, as indicated by different arrows in Figures 1 and 2; the same air flow is then brought, via the conduit 9, into the conduit 8, where it circulates in contact with some of the walls of the case 7 where the potentiometer 5 and the electronic circuit 6 are housed; the air which thus cools the electrical components 1, 5 and 6, then passes, via the outlet pipe 11, in a pipe 14 (FIGS. 1 and 2), which brings it to the inlet pipe , 15, from the shoemaker, 16, from the motor-fan unit, 17, from the apparatus; as indicated in FIG. 2, by arrows, the air brought into the case 16 through the inlet pipe 15, circulates there in the interval arranged between the wall of said case 16 and the motor-fan unit 17, so as to cool the latter and also the interior of this group 17, in particular the armature of the Sectric motor ss it is of course the turbine 17a of the fan which creates in the bolier 16 a sufficient depression to suck in the air outside through the cooling circuit 13-10-9-8-11-14-15.

La présente invention n'est pas limitée à la forme de réalisation précédemment décrite. Elle englobe toutes ses variantes organe de réglage du flux d'air est susceptible de réalisations connues, différentes d'un volet pivotant. The present invention is not limited to the embodiment described above.
