Dans un véhicule climatisé, est toujours présent une boîte de dégazage sur le circuit de refroidissement du moteur et un échangeur thermique pour le circuit de climatisation, mais ces deux éléments ne cohabitent pas ensemble et sont positionnés de manière distinctes dans le compartiment moteur du véhicule.In an air-conditioned vehicle, there is always a degassing box on the engine cooling circuit and a heat exchanger for the air conditioning circuit, but these two elements do not cohabit together and are positioned separately in the engine compartment of the vehicle.
De plus, lorsqu’il fait chaud, le compartiment moteur monte à des températures élevées, diminuant l’efficacité de l’échangeur thermique du le circuit de climatisation faisant que celui-ci est généralement surdimensionné et prend donc une place importante.In addition, when it is hot, the engine compartment rises to high temperatures, reducing the efficiency of the heat exchanger of the air conditioning circuit causing it to be generally oversized and therefore take up an important space.
Le dispositif selon l’invention permet de remédier à cet inconvénient.The device according to the invention overcomes this drawback.
Il comporte en effet, selon l’invention, un ensemble constitué par une boîte de dégazage pour un circuit de refroidissement d’un moteur et par un échangeur thermique d’un circuit de climatisation, le circuit de refroidissement comportant une circulation d’un fluide de refroidissement, ledit fluide de refroidissement du circuit de refroidissement pouvant contenir du gaz qui est extrait par circulant dudit fluide de refroidissement dans ladite boîte de dégazage, ladite boîte de dégazage comportant une partie inférieure qui forme une cuvette et qui est adaptée pour, lors du fonctionnement normal du véhicule, être remplie du fluide de refroidissement à dégazer, tel que dans ladite cuvette est positionnée, en immersion dans le fluide de refroidissement, l’échangeur thermique du circuit de climatisation.It comprises in fact, according to the invention, an assembly constituted by a degassing box for a cooling circuit of an engine and by a heat exchanger for an air conditioning circuit, the cooling circuit comprising a circulation of a fluid cooling circuit, said cooling fluid of the cooling circuit being able to contain gas which is extracted by circulating said cooling fluid in said degassing box, said degassing box comprising a lower part which forms a basin and which is adapted for, during the normal operation of the vehicle, be filled with the cooling fluid to be degassed, such that in said bowl is positioned, immersed in the cooling fluid, the heat exchanger of the air conditioning circuit.
Selon une première caractéristique de l’invention, le fond de la cuvette comporte au moins deux ouvertures pour l’alimentation en fluide de climatisation de l’échangeur thermique, chaque ouverture pouvant être prolongée par un raccord qui s’étend hors de la cuvette.According to a first characteristic of the invention, the bottom of the bowl has at least two openings for supplying air conditioning fluid to the heat exchanger, each opening being able to be extended by a connector which extends out of the bowl.
Selon une deuxième caractéristique de l’invention, l’échangeur thermique comporte des plaques d’échange thermiques permettant de refroidir un fluide du circuit de climatisation, lesdites plaques étant en permanence immergées dans le fluide de refroidissement du circuit de refroidissement, les plaques de l’échangeur thermique étant généralement formées dans une matière métallique.According to a second characteristic of the invention, the heat exchanger comprises heat exchange plates making it possible to cool a fluid of the air conditioning circuit, said plates being permanently immersed in the cooling fluid of the cooling circuit, the plates of the heat exchanger being generally formed in a metallic material.
Selon une troisième caractéristique de l’invention, le fond de la cuvette forme aussi le fond de l’échangeur thermique.According to a third characteristic of the invention, the bottom of the bowl also forms the bottom of the heat exchanger.
Selon une quatrième caractéristique de l’invention, les plaques de l’échangeur thermiques sont maintenues en position par des moyens de fixation qui sont solidaires du fond de la cuvette.According to a fourth characteristic of the invention, the plates of the heat exchanger are held in position by fixing means which are integral with the bottom of the bowl.
Selon une cinquième caractéristique de l’invention, la cuvette est formée dans une matière plastique.According to a fifth characteristic of the invention, the bowl is formed in a plastic material.
La présente invention concerne aussi un véhicule qui comporte un circuit de refroidissement d’un moteur par circulation d’un fluide de refroidissement et un circuit de climatisation qui comporte un tel ensemble constitué par une boîte de dégazage pour le circuit de refroidissement du moteur et par un échangeur thermique du circuit de climatisation.The present invention also relates to a vehicle which comprises a circuit for cooling an engine by circulation of a cooling fluid and an air conditioning circuit which comprises such an assembly consisting of a degassing box for the cooling circuit of the engine and by a heat exchanger of the air conditioning circuit.
Les dessins annexés illustrent l’invention :The accompanying drawings illustrate the invention:
En référence à la figure unique 1, un véhicule comporte une boîte de dégazage 1 pour un circuit de refroidissement d’un moteur et un échangeur thermique 2 d’un circuit de climatisation.With reference to the single figure 1, a vehicle comprises a degassing box 1 for a cooling circuit of an engine and a heat exchanger 2 for an air conditioning circuit.
Le circuit de refroidissement comporte une circulation d’un fluide de refroidissement 3, ledit fluide de refroidissement 3 du circuit de refroidissement pouvant contenir du gaz qui est extrait par circulant dudit fluide de refroidissement 3 dans la boîte de dégazage 1.The cooling circuit comprises a circulation of a cooling fluid 3, said cooling fluid 3 of the cooling circuit possibly containing gas which is extracted by circulating said cooling fluid 3 in the degassing box 1.
La boîte de dégazage 1 comporte une partie inférieure 11 qui forme une cuvette et qui est adaptée pour, lors du fonctionnement normal du véhicule, être remplie du fluide de refroidissement 3 à dégazer, de telle sorte que dans la cuvette 11 est positionnée en immersion dans le fluide de refroidissement 3, sur le fond 12 de la cuvette 11, l’échangeur thermique 2 du circuit de climatisation.The degassing box 1 comprises a lower part 11 which forms a bowl and which is adapted to, during normal operation of the vehicle, be filled with the cooling fluid 3 to be degassed, so that in the bowl 11 is positioned immersed in the cooling fluid 3, on the bottom 12 of the bowl 11, the heat exchanger 2 of the air conditioning circuit.
La boîte de dégazage 1 comporte aussi un orifice d’entrée 13 du fluide de refroidissement 3 qui est positionné au-dessus du niveau de la cuvette 11, un orifice de sortie 14 du fluide de refroidissement 3 qui est positionné au fond 12 de la cuvette 11 et un bouchon 15 permettant de compléter le niveau du fluide de refroidissement 3 dans la cuvette 11 au cas où le niveau soit trop bas.The degassing box 1 also comprises an inlet 13 of the cooling fluid 3 which is positioned above the level of the bowl 11, an outlet orifice 14 of the cooling fluid 3 which is positioned at the bottom 12 of the bowl 11 and a cap 15 allowing the level of the cooling fluid 3 in the basin 11 to be topped up in the event that the level is too low.
Le fond 12 de la cuvette 11 comporte deux ouvertures 21 pour l’alimentation en fluide de climatisation de l’échangeur thermique 2.The bottom 12 of the bowl 11 has two openings 21 for supplying air conditioning fluid to the heat exchanger 2.
Chaque ouverture 21 est prolongée par un raccord 22 qui s’étend hors de la cuvette 11.Each opening 21 is extended by a connector 22 which extends out of the bowl 11.
L’échangeur thermique 2 comporte des paques 23 d’échange thermiques permettant de refroidir un fluide du circuit de climatisation, les plaques 23 étant en permanence immergées dans le fluide du circuit de refroidissement 3.The heat exchanger 2 comprises heat exchange pads 23 making it possible to cool a fluid of the air conditioning circuit, the plates 23 being permanently immersed in the fluid of the cooling circuit 3.
Les plaques 23 de l’échangeur thermiques 2 sont en métal et sont fixées sur le fond 12 de la cuvette 11 de la boîte de dégazage 1, faisant que des moyens de fixation sont directement formés dans le fond 12 de la cuvette 11 pour maintenir mes plaques 23.The plates 23 of the heat exchanger 2 are made of metal and are fixed to the bottom 12 of the bowl 11 of the degassing box 1, so that fixing means are directly formed in the bottom 12 of the bowl 11 to maintain my plates 23.
De manière classique, la boîte de dégazage 1 est formée dans une matière plastique faisant que les moyens de fixation pour maintenir les plaques 23 sont directement formées lors du moulage de la boîte de dégazage 1.Conventionally, the degassing box 1 is formed in a plastic material so that the fixing means for holding the plates 23 are directly formed during the molding of the degassing box 1.
Ainsi agencé, le volume de fluide de refroidissement 3 de la cuvette 11, qui est nécessaire pour assurer un bon dégazage du fluide de refroidissement 3, est aussi exploité pour optimiser les performances de la climatisation du véhicule en améliorant les performances de l’échangeur thermique 2.Thus arranged, the volume of cooling fluid 3 of the bowl 11, which is necessary to ensure good degassing of the cooling fluid 3, is also used to optimize the performance of the air conditioning of the vehicle by improving the performance of the heat exchanger 2.
Le volume de la cuvette 11 qui est de l’ordre de 1,5 litres, associé au débit du fluide de refroidissement 3 qui peut aller jusqu’à 15 litres par minutes est suffisant pour un tel refroidissement du fluide de climatisation de l’échangeur thermique 2.The volume of the basin 11 which is of the order of 1.5 liters, associated with the flow rate of the cooling fluid 3 which can go up to 15 liters per minute is sufficient for such cooling of the air conditioning fluid of the exchanger thermal 2.
En plus de ce gain de performance, il apparait aussi un gain de place du fait et un gain de temps lors du montage en usine finale d’assemblage du véhicule avec moins de fixations et moins de pièces à assembler.In addition to this performance gain, it also appears to save space and save time during assembly in the final assembly plant of the vehicle with fewer fasteners and fewer parts to assemble.
