Description

ECHANGEUR THERMIQUE ET INSTALLATION DE GESTION THERMIQUE CORRESPONDANTE HEAT EXCHANGER AND CORRESPONDING HEAT MANAGEMENT INSTALLATION
La présente invention concerne la régulation thermique et, plus particulièrement, un échangeur thermique utilisé pour cette régulation thermique, ainsi que son placement au sein d'une installation de gestion thermique pour, notamment, la régulation thermique des batteries d'un véhicule électrique ou hybride. La régulation thermique des batteries, notamment dans le domaine automobile, et encore plus particulièrement des véhicules électriques et hybrides, est un point important car, si les batteries sont soumises à des températures trop froides, leur autonomie peut décroitre fortement et, si elles sont soumises à des températures trop importantes, il y a un risque d'emballement thermique pouvant aller jusqu'à la destruction de la batterie. Afin de réguler la température des batteries, il est connu d'ajouter un dispositif de régulation de température du module batterie. Ces dispositifs utilisent généralement des fluides caloporteurs circulant, par exemple, au moyen d'une pompe, dans un circuit de gestion thermique, ledit circuit de gestion thermique passant au sein d'un échangeur thermique en contact direct avec les batteries.The present invention relates to thermal regulation and, more particularly, to a heat exchanger used for this thermal regulation, as well as its placement within a thermal management installation for, in particular, the thermal regulation of the batteries of an electric or hybrid vehicle . The thermal regulation of batteries, particularly in the automotive field, and even more particularly in electric and hybrid vehicles, is an important point because, if the batteries are subjected to temperatures that are too cold, their autonomy can decrease significantly and, if they are subjected to at temperatures that are too high, there is a risk of thermal runaway which could lead to the destruction of the battery. In order to regulate the temperature of the batteries, it is known to add a device for regulating the temperature of the battery module. These devices generally use heat transfer fluids circulating, for example, by means of a pump, in a thermal management circuit, said thermal management circuit passing within a heat exchanger in direct contact with the batteries.
Les fluides caloporteurs peuvent ainsi absorber de la chaleur émise par la ou les batteries afin de les refroidir et évacuer cette chaleur au niveau d'un ou plusieurs autres échangeurs thermiques comme, par exemple, un radiateur ou un échangeur thermique relié à une autre boucle de gestion thermique comme, par exemple, une boucle de climatisation qui va absorber cette chaleur pour la disperser à l'extérieur ou alors l'utiliser pour aider au chauffage de l'habitacle. The heat transfer fluids can thus absorb heat emitted by the battery(ies) in order to cool them and evacuate this heat to one or more other heat exchangers such as, for example, a radiator or a heat exchanger connected to another heat exchanger loop. thermal management such as, for example, an air conditioning loop which will absorb this heat to disperse it outside or use it to help heat the passenger compartment.
Les fluides caloporteurs peuvent également, si besoin est, apporter de la chaleur pour réchauffer lesdites batteries, par exemple le circuit de gestion thermique peut comporter une résistance électrique ou un chauffage par thermistance Coefficient Positif de Température (CTP). The heat transfer fluids can also, if necessary, provide heat to heat said batteries, for example the thermal management circuit can include an electrical resistance or heating by Positive Temperature Coefficient (PTC) thermistor.
Les fluides caloporteurs généralement utilisés sont l'air ambiant ou des liquides comme par exemple l'eau. Les liquides étant meilleurs conducteurs de chaleur que les gaz, c'est une solution qui est privilégiée, car plus efficace. The heat transfer fluids generally used are ambient air or liquids such as water. Liquids being better conductors of heat than gases, this is a preferred solution because it is more efficient.
Néanmoins, l'ajout d'un tel dispositif de chauffage au sein du circuit de gestion thermique peut conduire à une augmentation de la place nécessaire à son intégration au sein du véhicule automobile et ne pas répondre aux exigences des constructeurs. However, the addition of such a heating device within the thermal management circuit may lead to an increase in the space required for its integration within the motor vehicle and may not meet the manufacturers' requirements.
Un des buts de la présente invention est donc de remédier au moins partiellement aux inconvénients de l'art antérieur et de proposer un échangeur de chaleur et une installation de gestion thermique améliorés.
