Description
La présente invention concerne un navire.The present invention relates to a ship.
Plus particulièrement, elle concerne un navire du type comportant au moins un local dans lequel sont logés des moyens électriques comprenant notamment au moins des moyens en forme de batterie de stockage d’énergie électrique.More particularly, it relates to a ship of the type comprising at least one room in which are housed electrical means comprising in particular at least means in the form of an electrical energy storage battery.
Ces navires qu’ils soient des bâtiments de surface ou des sous-marins, sont équipés de tels moyens de stockage d’énergie électrique qui peuvent se présenter en très grande quantité.These ships, whether they are surface ships or submarines, are equipped with such means of storing electrical energy which can be present in very large quantities.
Ainsi par exemple on sait qu’actuellement on embarque à bord de ces navires un très grand nombre de batteries au lithium-ion.For example, we know that a very large number of lithium-ion batteries are currently on board these ships.
Or les règles de conception de ces locaux notamment à bord de navires tels que des sous-marins, imposent en particulier des moyens de lutte incendie lorsque la batterie est opérationnelle.However, the design rules for these premises, in particular on board ships such as submarines, impose in particular fire-fighting means when the battery is operational.
On sait en effet que la sécurité de ces locaux est essentielle et il est nécessaire de démontrer qu’en cas d’évènement redouté, tel que par exemple une explosion, un dégazage, etc… sur un accumulateur ou un groupe d’accumulateurs de la batterie, il n’y aura pas de propagation aux autres accumulateurs ou aux autres groupes voisins d’accumulateurs.We know that the safety of these premises is essential and it is necessary to demonstrate that in the event of a feared event, such as for example an explosion, degassing, etc. on an accumulator or a group of accumulators of the battery, there will be no propagation to other accumulators or to other neighboring groups of accumulators.
De plus en matière d’isolement électrique, des études en cours ont montré que des distances d’isolement ainsi que des longueurs de lignes de fuite dans l’air, ont un impact fort sur l’architecture mécanique de l’ensemble du système.In addition, in terms of electrical insulation, studies in progress have shown that insulation distances as well as the lengths of air leakage lines have a strong impact on the mechanical architecture of the entire system.
Enfin la réfrigération de ces moyens de stockage d’énergie est essentielle pour garantir la durée de vie ainsi que la sécurité de l’ensemble.Finally, the refrigeration of these energy storage means is essential to guarantee the lifespan as well as the safety of the whole.
On conçoit alors que les solutions actuelles basées sur l’inertage par exemple à l’azote du local présentent un certain nombre d’inconvénients.It is therefore conceivable that the current solutions based on inerting, for example with nitrogen, of the premises have a certain number of drawbacks.
On sait par ailleurs que des appareils tels que des transformateurs ou autres peuvent être remplis de fluide diélectrique pour en assurer la sécurité de fonctionnement et le refroidissement.It is also known that devices such as transformers or the like can be filled with dielectric fluid to ensure operational safety and cooling.
Le but de l’invention est donc d’optimiser la sécurité des navires et en particulier des locaux destinés à recevoir des moyens électriques comprenant notamment au moins des moyens en forme de batterie de stockage d’énergie.The object of the invention is therefore to optimize the safety of ships and in particular of premises intended to receive electrical means comprising in particular at least means in the form of an energy storage battery.
A cet effet l’invention a pour objet un navire de type comportant au moins un local dans lequel sont logés des moyens électriques comprenant notamment au moins des moyens en forme de batterie de stockage d’énergie électrique, caractérisé en ce que le local est rempli d’un fluide diélectrique.To this end, the subject of the invention is a ship of the type comprising at least one room in which are housed electrical means comprising in particular at least means in the form of an electrical energy storage battery, characterized in that the room is filled of a dielectric fluid.
Suivant d’autres caractéristiques du navire selon l’invention, prises seules ou en combinaison :According to other characteristics of the vessel according to the invention, taken alone or in combination:
- le local est associé à des moyens en forme de vase d’expansion du fluide ;- the room is associated with means in the form of a fluid expansion vessel;
- le local est associé à des moyens de vidange du fluide ;- the room is associated with means for emptying the fluid;
- le local est associé à des moyens de brassage du fluide ;- the room is associated with fluid mixing means;
- le local est associé à des moyens de refroidissement du fluide ;- the room is associated with means of cooling the fluid;
- le fluide diélectrique est de l’huile ;- the dielectric fluid is oil;
- les moyens en forme de batterie comportent des batteries au lithium-ion.- The means in the form of a battery comprise lithium-ion batteries.
L’invention sera mieux comprise à l’aide de la description qui va suivre donnée uniquement à titre d’exemple et faite en se référant au dessin annexé qui représente une vue en coupe schématique d’une portion d’un navire et en particulier d’un local de celui-ci dans lequel sont logés des moyens électriques comprenant au moins des moyens en forme de batterie de stockage d’énergie électrique.The invention will be better understood with the aid of the following description given solely by way of example and made with reference to the appended drawing which represents a schematic sectional view of a portion of a ship and in particular of a room thereof in which are housed electrical means comprising at least means in the form of an electrical energy storage battery.
On a en effet illustré sur cette figure, une portion d’un navire désigné par la référence générale 1 sur cette figure.This figure indeed illustrates a portion of a ship designated by the general reference 1 in this figure.
Cette portion de navire comporte au moins un local désigné par la référence générale 2, dans lequel sont logés des moyens électriques comprenant notamment au moins des moyens en forme de batterie de stockage d’énergie électrique, ces moyens électriques étant désignés par la référence générale 3 sur cette figure.This portion of the ship comprises at least one room designated by the general reference 2, in which are housed electrical means comprising in particular at least means in the form of an electrical energy storage battery, these electrical means being designated by the general reference 3 in this figure.
Ces moyens en forme de batterie comprennent par exemple des batteries au lithium-ion.These means in the form of a battery include, for example, lithium-ion batteries.
Selon l’invention, le local 2 est rempli d’un fluide diélectrique désigné par la référence générale 5 sur cette figure.According to the invention, the room 2 is filled with a dielectric fluid designated by the general reference 5 in this figure.
Le local est entièrement rempli de fluide et les moyens de stockage d’énergie électrique sont alors entourés de ce fluide.The room is completely filled with fluid and the electrical energy storage means are then surrounded by this fluid.
Comme cela est illustré sur cette figure, le local 2 est alors associé à :As shown in this figure, room 2 is then associated with:
- des moyens en forme de vase d’expansion du fluide désignés par la référence générale 6 ;- means in the form of a fluid expansion vessel designated by the general reference 6;
- des moyens de vidange du fluide désignés par la référence générale 7 ;- Means for emptying the fluid designated by the general reference 7;
- des moyens de brassage du fluide dans le local désignés par la référence générale 8 ; et- means for mixing the fluid in the room designated by the general reference 8; And
- des moyens de refroidissement du fluide désignés par la référence générale 9.- fluid cooling means designated by the general reference 9.
Ces différents moyens peuvent présenter n’importe quelle structure appropriée.These various means may have any suitable structure.
Le fluide diélectrique 5 peut alors être de l’huile ou tout autre fluide ayant des caractéristiques diélectriques qui assure trois fonctions : diélectrique, caloporteur et retardateur de flamme.The dielectric fluid 5 can then be oil or any other fluid having dielectric characteristics which provides three functions: dielectric, heat carrier and flame retardant.
On conçoit alors qu’une telle structure présente un certain nombre d’avantages notamment au niveau de sa fiabilité et au niveau d’un certain nombre de points comme par exemple la suppression des organes de refroidissement de chaque branche des moyens de stockage et de la tuyauterie associée.It is then conceivable that such a structure has a certain number of advantages, in particular in terms of its reliability and in terms of a certain number of points, such as for example the elimination of the cooling members of each branch of the storage means and of the associated piping.
D’autres avantages sont liés à une réduction des volumes morts nécessaires à l’isolement électrique, à une augmentation de l’énergie embarquée et donc une augmentation des performances en autonomie du navire et à la possibilité d’intégrer la batterie à l’extérieur de la coque épaisse par exemple d’un navire tel qu’un sous-marin.Other advantages are linked to a reduction in the dead volumes necessary for electrical isolation, an increase in onboard energy and therefore an increase in the vessel's performance in terms of autonomy, and the possibility of integrating the battery outside. of the thick hull, for example of a ship such as a submarine.
Au niveau des moyens de stockage d’énergie l’invention présente plusieurs avantages.At the level of the energy storage means, the invention has several advantages.
En effet elle permet la résolution de la problématique de la propagation par voie thermique d’évènements redoutés au niveau des accumulateurs et des groupes d’accumulateurs.Indeed it allows the resolution of the problem of the thermal propagation of dreaded events at the level of the accumulators and groups of accumulators.
Elle permet par exemple de s’affranchir d’un espacement de sécurité important entre accumulateurs, et donc de disposer d’un système plus compact.It makes it possible, for example, to dispense with a large safety spacing between accumulators, and therefore to have a more compact system.
L’invention permet également une simplification de la solution de réfrigération/ventilation du système de batterie.The invention also allows a simplification of the refrigeration/ventilation solution of the battery system.
Le fluide permet en effet de réfrigérer l’ensemble des accumulateurs électroniques.The fluid makes it possible to cool all the electronic accumulators.
Ceci permet de supprimer la plaque froide qui permet de réfrigérer les accumulateurs, le réseau de distribution d’eau ainsi que le dispositif de ventilation du local.This makes it possible to eliminate the cold plate which makes it possible to refrigerate the accumulators, the water distribution network as well as the ventilation device of the room.
L’invention permet également de réduire les distances d’isolement comme indiqué précédemment ce qui se traduit par une augmentation globale de la fiabilité de fonctionnement de l’ensemble.The invention also makes it possible to reduce the isolation distances as indicated above, which translates into an overall increase in the operating reliability of the assembly.
Au niveau du navire, on peut également noter la suppression des groupes de ventilation dans le local, de traitement des gaz produits par un emballement thermique des accumulateurs, du dispositif de gestion de l’inertage et enfin du risque de fuite d’azote dans le navire.At the level of the ship, we can also note the removal of the ventilation units in the room, of the treatment of gases produced by thermal runaway of the accumulators, of the inerting management device and finally of the risk of nitrogen leakage in the ship.
Bien entendu d’autres dispositions et modes de réalisation peuvent être envisagés.Of course, other arrangements and embodiments can be envisaged.
