Domaine de l'invention La présente invention concerne un élément d'échange de chaleur adapté pour permettre l'échange de chaleur entre un premier et un deuxième fluide. Plus précisément, l'invention concerne un élément d'échange de chaleur adapté pour guider, en son intérieur un premier fluide et, en son extérieur un deuxième fluide afin de permettre un échange de chaleur au travers de la paroi de l'élément d'échange de chaleur. Field of the Invention The present invention relates to a heat exchange element adapted to allow the exchange of heat between a first and a second fluid. More specifically, the invention relates to a heat exchange element adapted to guide, in its interior a first fluid and, outside a second fluid to allow heat exchange through the wall of the element of heat exchange.
Etat de la technique State of the art
Dans un système de climatisation, par exemple un système de climatisation destiné à un véhicule automobile, un fluide frigorigène ou réfrigérant utilisé pour refroidir l'habitacle dudit véhicule automobile circule à l'intérieur d'un échangeur de chaleur, tel qu'un condenseur par exemple, lors d'un cycle de refroidissement. In an air conditioning system, for example an air conditioning system for a motor vehicle, a refrigerant or refrigerant used to cool the passenger compartment of said motor vehicle circulates inside a heat exchanger, such as a condenser by example, during a cooling cycle.
Dans l'art antérieur, il est connu d'obtenir le refroidissement d'un réfrigérant à l'aide d'un échangeur de chaleur, ledit échangeur de chaleur étant adapté pour permettre un échange de chaleur entre le réfrigérant et un fluide, tel que de l'eau, pour refroidir ledit réfrigérant. In the prior art, it is known to obtain the cooling of a refrigerant using a heat exchanger, said heat exchanger being adapted to allow a heat exchange between the refrigerant and a fluid, such as water to cool said refrigerant.
Dans ce but, l'échangeur de chaleur, selon l'art antérieur, comprend deux circuits distincts, l'un destiné au réfrigérant, l'autre destiné au fluide pour refroidir le réfrigérant. Ainsi, l'art antérieur divulgue l'utilisation d'un échangeur de chaleur comprenant un faisceau d'échange, dans lequel ledit faisceau d'échange comprend un empilement de tubes. Le réfrigérant peut circuler à l'intérieur des tubes, d'une première extrémité vers une deuxième extrémité des tubes. Le fluide utilisé pour refroidir le réfrigérant circule à contre-courant du réfrigérant, depuis la deuxième extrémité vers la première extrémité des tubes, entre les deux tubes adjacents. For this purpose, the heat exchanger, according to the prior art, comprises two separate circuits, one for the refrigerant, the other for the fluid to cool the refrigerant. Thus, the prior art discloses the use of a heat exchanger comprising an exchange beam, wherein said exchange beam comprises a stack of tubes. The refrigerant can circulate inside the tubes, from a first end to a second end of the tubes. The fluid used to cool the refrigerant circulates against the current of the refrigerant, from the second end to the first end of the tubes, between the two adjacent tubes.
Selon l'art antérieur, les tubes comprennent une paroi d'une épaisseur déterminée pour supporter la haute pression à laquelle est soumis le réfrigérant circulant à l'intérieur desdits tubes. L'échange de chaleur entre le réfrigérant et le fluide est réalisé au travers de cette paroi. Afin d'améliorer l'efficacité de l'échange de chaleur, il est possible de fournir, sur la paroi interne des tubes, des éléments en forme de protubérances qui s'étendent vers l'intérieur des tubes afin d'augmenter la surface de contact à l'intérieur des tubes. Cependant, cette solution est coûteuse et complexe à mettre en œuvre. According to the prior art, the tubes comprise a wall of a thickness determined to withstand the high pressure to which the refrigerant circulating inside said tubes is subjected. The heat exchange between the refrigerant and the fluid is carried out through this wall. In order to improve the efficiency of the heat exchange, it is possible to provide, on the inner wall of the tubes, protuberance-shaped elements which extend towards the inside of the tubes in order to increase the surface of the tube. contact inside the tubes. However, this solution is expensive and complex to implement.
Des solutions permettant d'améliorer l'échange de chaleur entre un premier fluide circulant à l'intérieur d'un élément d'échange d'un échangeur de chaleur et un deuxième fluide circulant à l'extérieur dudit échangeur de chaleur s'avèrent nécessaires afin d'accroître l'efficacité de l'échange de chaleur. Solutions for improving the heat exchange between a first fluid flowing inside an exchange element of a heat exchanger and a second fluid flowing outside said heat exchanger are necessary to increase the efficiency of the heat exchange.

Description détaillée des modes de réalisation La description ci-après a pour but d'exposer l'invention de manière suffisamment claire et complète, notamment à l'aide d'exemples, mais ne doit pas être considérée comme limitant l'étendue de la protection aux modes de réalisation particuliers et aux exemples présentés ci-après. La figure 1 représente une vue éclatée d'un échangeur de chaleur 1 selon l'invention. L'échangeur de chaleur 1 est particulièrement adapté pour être utilisé au cours d'un cycle de refroidissement d'un système de climatisation, par exemple au sein d'un véhicule automobile. DETAILED DESCRIPTION OF THE EMBODIMENTS The following description is intended to explain the invention in a sufficiently clear and complete manner, in particular by means of examples, but should not be considered as limiting the scope of protection. to the particular embodiments and examples presented hereinafter. FIG. 1 represents an exploded view of a heat exchanger 1 according to the invention. The heat exchanger 1 is particularly suitable for use during a cooling cycle of an air conditioning system, for example in a motor vehicle.
Comme montré sur la figure 1, l'échangeur de chaleur 1 est adapté pour recevoir le réfrigérant selon la direction de la flèche 20, à une température et une pression relativement élevées. L'échangeur de chaleur 1 comprend un ensemble de tubes, espacés entre eux et adaptés pour résister à la température et à la pression relativement élevées du réfrigérant. Le réfrigérant est guidé à l'intérieur de l'échangeur de chaleur 1 depuis son entrée en direction d'une sortie, selon la direction de la flèche 21 sur la figure 1. Afin de refroidir le réfrigérant, un liquide de refroidissement, tel que de l'eau, est introduit dans l'échangeur de chaleur 1 selon la direction de la flèche 22, le liquide de refroidissement circule à contre-courant du réfrigérant, permettant ainsi un échange de chaleur entre le réfrigérant et le liquide de refroidissement au sein de l'échangeur de chaleur 1. Ensuite, le liquide de refroidissement est guidé vers une sortie selon la direction de la flèche 23. L'échangeur de chaleur 1 est ainsi adapté pour faciliter le déplacement du liquide de refroidissement à l'intérieur de l'espace entre les différents tubes utilisés pour la circulation du réfrigérant.  As shown in Figure 1, the heat exchanger 1 is adapted to receive refrigerant in the direction of the boom 20, at a relatively high temperature and pressure. The heat exchanger 1 comprises a set of tubes, spaced apart and adapted to withstand the relatively high temperature and pressure of the refrigerant. The refrigerant is guided inside the heat exchanger 1 from its entrance towards an outlet, in the direction of the arrow 21 in FIG. 1. In order to cool the refrigerant, a coolant, such as water, is introduced into the heat exchanger 1 in the direction of the arrow 22, the coolant circulates against the current of the refrigerant, thus allowing a heat exchange between the refrigerant and the cooling liquid within of the heat exchanger 1. Then, the coolant is guided to an outlet in the direction of the arrow 23. The heat exchanger 1 is thus adapted to facilitate the movement of the coolant within the interior of the room. space between the different tubes used for refrigerant circulation.
En effet, l'échangeur de chaleur 1 comprend un boîtier comportant une paroi supérieure 2, une paroi inférieure 3 et deux parois latérales 4, 5.

L'élément d'échange de chaleur 31 comprend une pluralité de canaux décrits ci-dessous et permettant la circulation du réfrigérant à l'intérieur dudit élément d'échange de chaleur 31. Figure 2 shows a detailed view of the heat exchange element 31 according to a first embodiment of the invention. The heat exchange element 31 comprises a plurality of channels described below and allowing the circulation of the refrigerant inside said heat exchange element 31.
La figure 3 montre une partie détaillée de l'élément d'échange de chaleur 31. Ainsi l'élément d'échange de chaleur 31 comprend une pluralité de canaux 42, 43, 44, 45. Les canaux 42, 43, 44, 45 permettent de guider, en leur intérieur, le réfrigérant, d'une première extrémité de l'élément d'échange de chaleur 31 vers l'extrémité opposée de l'élément d'échange de chaleur 31.

Les canaux pairs 42, 44 sont positionnés sur un premier plan horizontal alors que les canaux impairs 41, 45 sont positionnés sur un deuxième plan horizontal. Chaque canal 42, 43, 44, 45 se présente sous une forme essentiellement cylindrique de manière à former un tube. Les différents canaux 42, 43, 44, 45 sont positionnés, chacun selon des plans verticaux parallèles entre eux. Les parois desdits canaux 42, 43, 44, 45 sont connectées les unes aux autres pour former l'élément d'échange de chaleur 31. FIG. 3 shows a detailed part of the heat exchange element 31. Thus, the heat exchange element 31 comprises a plurality of channels 42, 43, 44, 45. The channels 42, 43, 44, 45 enable the refrigerant to be guided from one end of the heat exchange element 31 to the opposite end of the heat exchange element 31. The first measurement makes it possible to increase the outer surface of the heat exchange element 31. The even channels 42, 44 are positioned on a first horizontal plane while the odd channels 41, 45 are positioned on a second horizontal plane. Each channel 42, 43, 44, 45 is in substantially cylindrical form so as to form a tube. The different channels 42, 43, 44, 45 are positioned, each in vertical planes parallel to each other. The walls of said channels 42, 43, 44, 45 are connected to each other to form the heat exchange element 31.
L'alternance des premier et deuxième plans horizontaux des canaux 42, 43, 44, 45 permet d'augmenter la surface extérieure de l'élément d'échange de chaleur 31 et d'accroître ainsi les possibilités d'échange de chaleur au travers des parois des canaux 42, 43, 44, 45, entre le réfrigérant circulant à l'intérieur des canaux et le liquide de refroidissement circulant à l'extérieur desdits canaux 42, 43, 44, 45. Comme montré sur la figure 2, l'élément d'échange de chaleur 31 est pourvu de plusieurs ondulations 52, 53, 54. Ces ondulations 52, 53, 54 permettent d'augmenter la longueur du chemin suivi par le réfrigérant à l'intérieur des différents canaux 42, 43, 44, 45, depuis la première extrémité vers la deuxième extrémité de l'élément d'échange de chaleur 31. Ainsi, la surface extérieure de l'élément d'échange de chaleur 31 est augmentée. Par conséquent, la quantité de chaleur, échangée entre le réfrigérant et le liquide de refroidissement, est également augmentée. The alternation of the first and second horizontal planes of the channels 42, 43, 44, 45 makes it possible to increase the external surface of the heat exchange element 31 and thus to increase the possibilities of heat exchange through the walls of the channels 42, 43, 44, 45, between the refrigerant circulating inside the channels and the cooling liquid circulating outside said channels 42, 43, 44, 45. As shown in FIG. 2, the heat exchange element 31 is provided with several corrugations 52, 53, 54. These corrugations 52, 53, 54 make it possible to increase the length of the path followed by the refrigerant inside. different channels 42, 43, 44, 45, from the first end to the second end of the heat exchange element 31. Thus, the outer surface of the heat exchange element 31 is increased. As a result, the amount of heat exchanged between the coolant and the coolant is also increased.
La combinaison des caractéristiques techniques décrites ci-dessus, concernant l'alternance des plans horizontaux des différents canaux 42, 43, 44, 45 et la présence des ondulations 52, 53, 54 garantit un échange de chaleur optimal entre le réfrigérant et le liquide de refroidissement utilisés au sein de l'échangeur de chaleur 1 selon la présente invention.
