Description
Dispositif portatif de dévidage d’un câble électrique, notamment un câble de charge pour un véhicule électrique ou hybridePortable device for unwinding an electric cable, in particular a charging cable for an electric or hybrid vehicle
La présente invention concerne un dispositif portatif de dévidage d’un câble électrique, notamment un câble de charge pour un véhicule électrique ou hybride.The present invention relates to a portable device for unwinding an electric cable, in particular a charging cable for an electric or hybrid vehicle.
Dans le contexte actuel de consensus autour du réchauffement climatique, la diminution des émissions de dioxyde de carbone (CO2) est un défi majeur auquel sont confrontés les constructeurs automobiles, les normes étant toujours plus exigeantes en la matière.In the current context of consensus around global warming, the reduction of carbon dioxide (CO2) emissions is a major challenge faced by car manufacturers, the standards being ever more demanding in this area.
Outre l’amélioration constante des rendements des moteurs thermiques classiques, qui s’accompagne d’une baisse des émissions de CO2, les véhicules électriques (« EV » d’après la terminologie anglo-saxonne « Electric Vehicle ») et les véhicules hybrides thermique-électrique (« HEV » d’après la terminologie anglo-saxonne « Hybrid Electric Vehicle ») sont aujourd’hui considérés comme la solution la plus prometteuse pour diminuer les émissions de CO2.In addition to the steady improvement in efficiency of conventional combustion engines, which is accompanied by a reduction in CO2 emissions, electric vehicles ("EV") and thermal hybrid vehicles. Electric ("HEV") is now considered the most promising solution for reducing CO2 emissions.
Différentes technologies de stockage de l’énergie électrique ont été testées dans les dernières années afin de répondre aux besoins des EV. Il apparaît aujourd’hui que les batteries à cellules lithium-ion (Li-ion) sont celles susceptibles de fournir le meilleur compromis entre la densité de puissance, qui favorise les performances en termes d’accélération notamment, et la densité d’énergie, qui favorise l’autonomie. Cependant, l’utilisation de cette technologie Li-ion pour constituer des batteries de traction pour EV n’est pas sans poser de nombreuses difficultés, notamment si l’on considère les niveaux de tension nécessaires aux bornes de la batterie, de l’ordre de 400 volts (V), ou encore les niveaux de puissance de recharge nécessaires, de l’ordre de 2 à 3 kilowatts-heure en charge lente pendant plusieurs heures, jusqu’à plusieurs dizaines de kilowatts-heure en charge rapide pendant quelques dizaines de minutes. A de tels niveaux de puissance de charge, le câble de charge lui-même est soumis à de fortes contraintes.Different technologies for storing electrical energy have been tested in recent years to meet the needs of EVs. It now appears that lithium-ion cell batteries (Li-ion) are those likely to provide the best compromise between the power density, which promotes the performance in terms of acceleration in particular, and the energy density, which promotes autonomy. However, the use of this Li-ion technology to form traction batteries for EV is not without posing many difficulties, especially if one considers the voltage levels required at the terminals of the battery, the order of 400 volts (V), or the necessary levels of charging power, of the order of 2 to 3 kilowatt-hours in slow charge for several hours, up to several tens of kilowatt-hours in rapid charge for a few tens minutes. At such load power levels, the charging cable itself is subjected to high stresses.
La solution la plus connue, qui est également la plus simple, est de fournir un câble de charge « volant » de grande section adaptée à la puissance de charge maximale envisagée, que l’on transporte dans le coffre du véhicule. Le principal inconvénient de cette solution est que, durant les phases de charge, le câble traîne par terre et se salit. Donc, soit l’utilisateur le replie proprement (ce qui peut s’avérer compliqué compte-tenu de sa section importante) avant de le ranger dans son coffre et il se salit les mains, soit il le pose en vrac dans le coffre et il y a un risque non négligeable qu’il doive le démêler lorsqu’il en aura à nouveau besoin. Se salir les mains semble donc inévitable, et il s’agit là d’un inconvénient que la présente invention se propose de résoudre.The best-known solution, which is also the simplest, is to provide a large-sized "flying" load cable adapted to the maximum load power envisaged, which is transported in the trunk of the vehicle. The main drawback of this solution is that during the charging phases, the cable drags on the ground and gets dirty. So, the user folds it cleanly (which can be complicated considering its important section) before storing it in his trunk and he gets his hands dirty, or he puts it loose in the trunk and he there is a significant risk that he must unravel it when he needs it again. Soiling the hands seems inevitable, and this is a disadvantage that the present invention proposes to solve.
Pour éviter cet inconvénient, il est connu de l’état de la technique, notamment de la demande de brevet US2015/0008878A1, un dispositif de stockage d’un câble de charge comportant un dévidoir muni d’une manivelle pour dérouler et enrouler le câble, ainsi que d’une poignée pour transporter le dispositif. Il comporte également un boîtier de contrôle de la charge, intégré au centre du dévidoir, qui permet notamment une recharge lente sur prise standard. Un inconvénient majeur de cette solution est le risque d’échauffement. En effet, à des niveaux de puissance élevés pour charge rapide, les problèmes d’échauffement ne se limitent pas à la batterie : tous les éléments conducteurs impliqués dégagent une grande quantité de chaleur par effet joule et il est nécessaire de prendre en compte ce phénomène lors de la conception de l’ensemble de l’architecture électrique du véhicule. Ainsi, non seulement le câble de charge reliant le véhicule à la borne de charge doit être choisi de section suffisamment importante, mais il doit également être agencé d’une manière permettant d’évacuer la chaleur de manière contrôlée. Ce n’est manifestement pas le cas d’une solution par enroulement comme dans US2015/0008878A1. L’invention a notamment pour but de surmonter les inconvénients précités, notamment ceux liés au risque d’échauffement. A cet effet, l’invention a pour objet un dispositif portatif de dévidage d’un câble électrique. Le corps du câble situé entre ses deux extrémités est contenu au moins partiellement dans un boîtier de rangement comportant deux ouvertures dont dépassent les deux extrémités du câble respectivement, ces extrémités étant chacune munie de moyens de connexion électrique. Le corps du câble est guidé dans le boîtier par une pluralité de moyens de guidage agencés de telle sorte que le corps du câble est apte, sur toute sa longueur contenue dans le boîtier, au refroidissement par convection naturelle ou forcée.To avoid this drawback, it is known from the state of the art, in particular patent application US2015 / 0008878A1, a device for storing a charging cable comprising a reel with a crank for unwinding and winding the cable. , as well as a handle for carrying the device. It also includes a load control box, integrated in the center of the reel, which allows a slow charging on standard socket. A major disadvantage of this solution is the risk of overheating. Indeed, at high power levels for fast charging, heating problems are not limited to the battery: all the conductive elements involved give off a large amount of heat by joule effect and it is necessary to take into account this phenomenon. when designing the entire electrical architecture of the vehicle. Thus, not only the load cable connecting the vehicle to the charging terminal must be selected of sufficiently large section, but it must also be arranged in a manner to remove heat in a controlled manner. This is clearly not the case of a winding solution as in US2015 / 0008878A1. The invention is intended in particular to overcome the aforementioned drawbacks, particularly those related to the risk of overheating. For this purpose, the subject of the invention is a portable device for feeding an electric cable. The body of the cable located between its two ends is contained at least partially in a storage box having two openings beyond which the two ends of the cable respectively, these ends being each provided with electrical connection means. The body of the cable is guided in the housing by a plurality of guide means arranged such that the body of the cable is capable, throughout its length contained in the housing, cooling by natural or forced convection.
Dans un mode de réalisation préféré, la pluralité de moyens de guidage peut inclure une pluralité de charriots, chacun desdits charriots pouvant être mobile sur au moins une glissière et apte à être ramené vers une position initiale de rangement sur ladite glissière par des moyens de rappel.In a preferred embodiment, the plurality of guiding means may include a plurality of trolleys, each of said trolleys being movable on at least one slideway and adapted to be brought back to an initial position of storage on said slideway by return means. .
Avantageusement, chacun des charriots peut comporter une bobine montée sur roues dans la glissière, la bobine pouvant comporter un nombre prédéterminé de roues à gorge aptes à accueillir une portion du câble.Advantageously, each of the trolleys may comprise a coil mounted on wheels in the slideway, the coil may comprise a predetermined number of grooved wheels adapted to accommodate a portion of the cable.
Par exemple, les moyens de rappel de chacun des charriots pouvant inclure au moins un ressort, la pluralité de moyens de guidage peut inclure en outre deux taquets coinceurs disposés à proximité des deux ouvertures dans le boîtier respectivement et dans lesquels peuvent passer les deux extrémités du câble respectivement, de manière à bloquer lesdites extrémités contre la force de rappel exercée par les ressorts.For example, the return means of each of the carriages may include at least one spring, the plurality of guide means may further include two cleats arranged near the two openings in the housing respectively and in which can pass both ends of the cable respectively, so as to block said ends against the restoring force exerted by the springs.
Par exemple, les moyens de rappel de chacun des charriots peuvent inclure au moins un lien de rappel attaché à un cordon central de tirage manuel dont une extrémité peut dépasser du boîtier par une troisième ouverture dans ledit boîtier.For example, the return means of each of the carriages may include at least one return link attached to a central manual draw cord, one end of which may protrude from the housing by a third opening in said housing.
Avantageusement, la pluralité de moyens de guidage peut inclure en outre deux guides cylindriques (59, 60) disposés à proximité des deux ouvertures du boîtier (13) dont dépassent les deux extrémités du câble (10) respectivement.Advantageously, the plurality of guiding means may further include two cylindrical guides (59, 60) disposed near the two openings of the housing (13) which protrude the two ends of the cable (10) respectively.
Un stop-cordon peut être disposé sur le cordon central de tirage à l’extérieur du boîtier, afin de bloquer chacun des charriots mobiles dans sa position initiale de rangement sur sa glissière.A cord stop can be placed on the central draw cord outside the housing, in order to lock each of the mobile carriages in its initial storage position on its slide.
Le boîtier peut comporter en outre des moyens de ventilation alimentés par le câble et disposés de manière à refroidir par convection forcée le corps dudit câble sur toute sa longueur contenue dans le boîtier.The housing may further comprise ventilation means powered by the cable and arranged to cool by forced convection the body of said cable over its entire length contained in the housing.
La présente invention a également pour objet un tel dispositif portatif de dévidage d’un câble de charge pour véhicule électrique ou hybride, un dispositif de régulation de charge étant disposé dans le boîtier le long du câble. Avantageusement, le dispositif de régulation de charge peut être disposé sensiblement au centre du boîtier.The present invention also relates to such a portable device for unwinding a charging cable for electric or hybrid vehicle, a charge control device being disposed in the housing along the cable. Advantageously, the charge control device may be disposed substantially in the center of the housing.
Outre ses avantages en termes de refroidissement, un dispositif selon la présente invention a encore pour principal avantage qu’il est ergonomique dans le sens où son utilisation ne nécessite pas de se salir les mains, et qu’il offre un encombrement limité, de sorte qu’on peut le ranger dans le coffre sans pénaliser le volume utile pour les bagages. D’autres caractéristiques et avantages de l’invention apparaîtront à l’aide de la description qui suit faite en regard de dessins annexés 1, 2a, 2b, 3a, 3b, 4 et 5 qui représentent schématiquement des variantes de réalisation de l’invention.In addition to its advantages in terms of cooling, a device according to the present invention also has the main advantage that it is ergonomic in the sense that its use does not require to get dirty hands, and that it offers a limited footprint, so that can be stored in the trunk without penalizing the useful volume for luggage. Other features and advantages of the invention will become apparent with the aid of the following description given with reference to the accompanying drawings 1, 2a, 2b, 3a, 3b, 4 and 5 which schematically represent alternative embodiments of the invention. .
Une idée directrice des variantes de réalisation illustrées ci-après est d’intégrer un câble de charge 10, ainsi que son dispositif 16 de régulation/protection conforme à la norme IEC61851-1, dans un boîtier 13 en forme de mallette par exemple, afin de proposer à l’utilisateur un produit ergonomique facile à manipuler et à ranger dans le coffre d’un véhicule.A guiding idea of the variant embodiments illustrated below is to integrate a charging cable 10, as well as its regulation / protection device 16 in accordance with the IEC61851-1 standard, into a box 13 in the form of a case, for example, so that to offer the user an ergonomic product easy to handle and store in the trunk of a vehicle.
Comme illustré par l’exemple de réalisation de la figure 1, sur laquelle seul le fond 132 du boîtier 13 en forme de mallette est visible pour des raisons de clarté, deux sorties sont nécessaires sur la mallette : d’un côté pour une fiche 12, raccordée à une portion 102 du câble 10, qui va se brancher dans une prise murale raccordée à un réseau de fourniture d’électricité, et de l’autre côté pour une fiche 11, raccordée à une portion 101 du câble 10, qui va se brancher dans une prise disposée sur le véhicule.As illustrated by the embodiment of Figure 1, in which only the bottom 132 of the case 13 in the form of a case is visible for reasons of clarity, two outputs are necessary on the case: one side for a plug 12 connected to a portion 102 of the cable 10, which will plug into a wall outlet connected to an electricity supply network, and the other side to a plug 11, connected to a portion 101 of the cable 10, which will plug into a socket on the vehicle.
Un dispositif de régulation 16 est disposé au centre du boîtier 13 en forme de mallette, de sorte à respecter, par l’intermédiaire de la portion 102 du câble 10, une distance maximale de 30 centimètres entre la prise murale et le dispositif de protection, cette distance étant requise par la norme IEC61851-1.A regulating device 16 is disposed in the center of the case 13 in the form of a case, so as to respect, via the portion 102 of the cable 10, a maximum distance of 30 centimeters between the wall outlet and the protection device, this distance is required by IEC61851-1.
Les pointillés illustrent schématiquement des glissières 17 dans lesquelles circulent, à partir d’une position initiale I de rangement, des chariots mobiles 15 entraînés par le câble 10. Ces charriots 15 sont schématiquement illustrés sur la figure 1 par des cylindres autour desquels le câble 10 vient partiellement se bobiner. Ils sont représentés plus en détails sur les figures 2a et 2b, qui illustrent des charriots mobiles 15 dans leurs positions initiales I de rangement et qui montrent que chaque charriot 15 comporte une bobine 152 pour accueillir partiellement le câble 10 autour d’un axe A. Il est important de comprendre que c’est ce bobinage partiel qui confère à l’invention son avantage principal par rapport aux solutions par enroulement : c’est lui qui assure que toute la longueur du câble contenue dans le boîtier est refroidie par convexion naturelle, aucune portion du câble 10 ne se retrouvant enfouie au cœur d’un enroulement. Dans l’exemple des figures 2a et 2b, les bobines 152 peuvent comporter chacune 4 roues à gorge 1521 de guidage du câble 10, empilées les unes sur les autres et séparées l’une de l’autre par une rondelle, et libres en rotation autour de l’axe A. Dans la position initiale de rangement illustrée par les figures 2a et 2b, les 4 roues à gorge accueillent chacune une portion du câble 10. Le dispositif selon l’invention est «plein», le câble 10 étant complètement rangé. Suivant la longueur de câble 10 nécessaire pour brancher ce dernier au véhicule, il suffit de tirer plus ou moins sur les portions 101 et 102 du câble 10, qui entraîne alors les roues 1521 en rotation autour de l’axe A. Chaque roue à gorge 1521 se met alors à tourner librement autour de l’axe A. Avantageusement, ces roues à gorge 1521 peuvent s’adapter à la vitesse de rotation du câble 10 autour du cylindre d’axe A, cette vitesse de rotation étant différente d’une roue à l’autre. Ceci jusqu’à ce que le dispositif selon l’invention soit «vide», le câble 10 étant totalement sorti. Le nombre de charriots mobiles 15, la taille des bobines 152, notamment le nombre de roues à gorge 1521, et par conséquent la taille du boîtier 13 en forme de mallette, sont à adapter à la longueur totale du câble 10 souhaitée.The dotted lines schematically illustrate slides 17 in which, from an initial position I of storage, moving carriages 15 driven by the cable 10 travel. These carriages 15 are schematically illustrated in FIG. 1 by cylinders around which the cable 10 partially comes winding. They are shown in greater detail in FIGS. 2a and 2b, which illustrate mobile carriages 15 in their initial storage positions I and which show that each carriage 15 comprises a coil 152 for partially accommodating the cable 10 about an axis A. It is important to understand that it is this partial winding that gives the invention its main advantage over winding solutions: it is it that ensures that the entire length of the cable contained in the housing is cooled by natural convection, no portion of the cable 10 being buried in the heart of a winding. In the example of FIGS. 2a and 2b, the coils 152 may each comprise 4 grooved wheels 1521 for guiding the cable 10, stacked one on the other and separated from one another by a washer, and free to rotate. around the axis A. In the initial storage position shown in Figures 2a and 2b, the four grooved wheels each accommodate a portion of the cable 10. The device according to the invention is "full", the cable 10 being completely tidy. Depending on the length of cable 10 necessary to connect the latter to the vehicle, it is sufficient to pull more or less on the portions 101 and 102 of the cable 10, which then drives the wheels 1521 in rotation about the axis A. Each grooved wheel 1521 is then rotated freely about the axis A. Advantageously, these grooved wheels 1521 can adapt to the speed of rotation of the cable 10 around the cylinder A axis, this speed of rotation being different from a wheel to another. This until the device according to the invention is "empty", the cable 10 being completely out. The number of moving carriages 15, the size of the rolls 152, in particular the number of grooved wheels 1521, and therefore the size of the case 13 in the form of a case, must be adapted to the total length of the desired cable 10.
Dans l’exemple de la figure 1, des taquets coinceurs 19 et 20 sont disposés dans le boîtier 13 à proximité immédiate des deux points de sortie des portions 101 et 102 respectivement, afin de guider la sortie du câble d’une part, et d’autre part de coincer le câble 10 lorsqu’il est sorti, de sorte qu’il ne s’exerce pas de force de rappel sur le câble 10 lorsque celui-ci est sorti totalement ou partiellement. En effet, cette force ravalerait inopportunément le câble 10 dans le boîtier 13. Les taquets 19 et 20 peuvent se décoincer par simple traction sur le câble 10. De tels taquets coinceur sont connus de l’état de la technique d’autres domaines.In the example of FIG. 1, cleats 19 and 20 are arranged in the housing 13 in the immediate vicinity of the two exit points of the portions 101 and 102 respectively, in order to guide the exit of the cable on the one hand, and on the other hand to wedge the cable 10 when it is released, so that it does not exert a restoring force on the cable 10 when it is totally or partially released. Indeed, this force would inappropriately reduce the cable 10 in the housing 13. The cleats 19 and 20 can be loosened by simply pulling on the cable 10. Such cleat levers are known from the state of the art of other areas.
Des guides cylindriques 21 peuvent être disposés entre le dispositif de régulation 16 et l’un des charriots 15 guidant la portion 102 du câble 10 vers l’extérieur du boîtier 13.Cylindrical guides 21 may be arranged between the regulating device 16 and one of the carriages 15 guiding the portion 102 of the cable 10 towards the outside of the casing 13.
Les figures 2a et 2b illustrent plus particulièrement deux exemples de réalisation de l’invention dans lesquels chaque charriot mobile 15 est rappelé par un ressort 18. Chaque charriot mobile 15 comporte un châssis 151 porté par quatre roues 153 et supportant une bobine 152 décrite précédemment. Comme explicité précédemment, s’agissant de la position initiale I de rangement, les bobines 152 sont pleines, leurs quatre roues à gorge 1521 accueillant une portion du câble 10, et les ressorts 18 ne sont pas en tension. C’est pour des raisons de fiabilité, notamment pour empêcher qu’ils se mettent de travers, que chaque charriot mobile 15 comporte 4 roues.Figures 2a and 2b illustrate more particularly two embodiments of the invention in which each movable carriage 15 is biased by a spring 18. Each movable carriage 15 comprises a frame 151 carried by four wheels 153 and supporting a coil 152 described above. As explained above, with regard to the initial position I of storage, the coils 152 are full, their four grooved wheels 1521 accommodating a portion of the cable 10, and the springs 18 are not in tension. It is for reasons of reliability, in particular to prevent them from going awry, that each mobile carriage 15 has 4 wheels.
Dans le mode de réalisation de la figure 2a, les glissières 17 sont disposées au-dessus et au-dessous des roues 153 du chariot 15. Dans le mode de réalisation de la figure 2b, les glissières 17 sont disposées à l’intérieur des roues du chariot 15. Mais on pourrait dans ce dernier cas envisager de limiter à 2 le nombre de roues du chariot 15.In the embodiment of Figure 2a, the slides 17 are disposed above and below the wheels 153 of the carriage 15. In the embodiment of Figure 2b, the slides 17 are disposed within the wheels of the carriage 15. But it could in this case consider limiting the number of wheels of the carriage 15 to 2.
Les figures 3a et 3b illustrent, par une vue de profil et une vue de haut respectivement, un exemple de réalisation de l’invention dans lequel le câble 10 est refroidi en utilisant une circulation d’air prélevé à l’extérieur au travers du capot supérieur 131 du boîtier 13, via une entrée d’air 31 et un ventilateur 32 par exemple.2FIGS. 3a and 3b illustrate, by a profile view and a top view, respectively, an exemplary embodiment of the invention in which the cable 10 is cooled by using a circulation of air drawn outside through the hood upper 131 of the housing 13, via an air inlet 31 and a fan 32 for example.2
La figure 4 illustre un exemple de réalisation de l’invention dans lequel le câble 10 est refroidi en utilisant un module pelletier 41 et des modules de brassage 42 et 43 disposés respectivement sur et sous le capot supérieur 131 du boîtier 13, de l’air se trouvant enfermé à l’intérieur du boîtier 13 et étant refroidi par le module pelletier 41, limitant ainsi les entrées d’air et donc de poussières dans le boîtier 13.FIG. 4 illustrates an exemplary embodiment of the invention in which the cable 10 is cooled by using a fitter module 41 and brewing modules 42 and 43 disposed respectively on and under the upper cover 131 of the housing 13, air being enclosed inside the housing 13 and being cooled by the furrier module 41, thus limiting the air and therefore dust inlets into the housing 13.
La figure 5 illustre un autre exemple de réalisation de l’invention, dans lequel les ressorts 18 et les taquets coinceurs 19 et 20 sont avantageusement remplacés par des liens 52, 53, 54, 55 et 56 de rappel des chariots 15, ces liens 52 à 56 passant respectivement dans des poulies 62, 63, 64, 65 et 66 centrées en bout de glissières 17 sur les positions initiales de rangement I sensiblement, et ces liens 52 à 56 étant tous attachés à un cordon central de tirage 51 sur lequel tire l’utilisateur pour ravaler le câble électrique 10 dans le boîtier 13 en remettant tous les charriots mobiles 15 dans leur position initiale I. Des guides cylindriques 60 et 59 guident avantageusement les portions 101 et 102 respectivement du câble 10 aux sorties du boîtier 13. L’avantage de ce mode de réalisation est la simplicité mécanique, source de fiabilité. Un stop-cordon 57 peut être disposé sur le cordon de tirage 51 afin de bloquer le câble 10 et les prises en position de rangement une fois le câble 10 complètement ravalé dans le boîtier 13.FIG. 5 illustrates another exemplary embodiment of the invention, in which the springs 18 and the jamming cleats 19 and 20 are advantageously replaced by links 52, 53, 54, 55 and 56 for biasing the carriages 15, these links 52 at 56 passing respectively in pulleys 62, 63, 64, 65 and 66 centered at the end of slides 17 on the initial storage positions I substantially, and these links 52 to 56 are all attached to a central draw cord 51 on which draws the user to swallow the electrical cable 10 in the housing 13 by putting all the mobile carriages 15 in their initial position I. Cylindrical guides 60 and 59 advantageously guide the portions 101 and 102 respectively of the cable 10 to the outputs of the housing 13. L advantage of this embodiment is the mechanical simplicity, source of reliability. A cord stopper 57 can be placed on the pull cord 51 in order to lock the cable 10 and the plugs in the storage position once the cable 10 has been completely cut in the casing 13.
Un des principaux avantages d’un dispositif selon l’invention est donc que le câble de charge n’est pas enroulé : il n’y a pas de contraintes thermiques additionnelles liées à un enroulement à prendre en compte durant la charge, notamment durant la charge rapide à forte puissance, ceci même lorsque le câble de puissance n’est que partiellement sorti de son boîtier, car toute la longueur du câble contenue dans le boîtier est refroidie au moins par convection naturelle, voire par convection forcée via un ventilateur. Il est aussi ergonomique et facile à ranger dans le coffre d’un véhicule. Enfin, son coût de mise en oeuvre est relativement faible.One of the main advantages of a device according to the invention is therefore that the charging cable is not wound: there are no additional thermal stresses related to a winding to be taken into account during charging, especially during the fast charging at high power, even when the power cable is only partially removed from its housing, because the entire length of the cable contained in the housing is cooled at least by natural convection or forced convection via a fan. It is also ergonomic and easy to store in the trunk of a vehicle. Finally, its implementation cost is relatively low.
