Description

REFROIDISSEUR POUR C30MPOSANTS ELECTRONIQUES
DE PUISSANCE
Dans de nombreux domaines, les composants électroniques de puissance doivent être montés sur des supports leur servant de refroidisseur. Il en est ainsi par exemple dans les chargeurs, les onduleurs, les variateurs, les appareils à souder, les contacteurs statiques... Dans tous les cas, chaque composant se termine par une tige filetée grâce à laquelle il est vissé dans un bloc qui est généralement réalisé par filage en un alliage à base d'aluminium et est muni de nervures pour la dissipation des calories.COOLER FOR C30 ELECTRONIC COMPONENTS
POWER
In many fields, the electronic power components must be mounted on supports which serve as coolers. This is the case, for example, in chargers, inverters, inverters, welding equipment, solid state contactors ... In any case, each component ends in a threaded rod thanks to which it is screwed into a block which is generally made by spinning an aluminum-based alloy and is provided with ribs for the dissipation of calories.

Le vissage des composants sur le refroidisseur amène à tarauder dans le bloc refroidisseur des trous dont le nombre et la position sont fonction du nombre des composants et de la disposition qui leur est prévue. Outre la nécessité d'une opération de perçage et de taraudage pour chaque composant, cet agencement conduit à une immuabilité dans le nombre et dans la position des composants, ce qui entraîne ultérieurement l'obligation de percer et de tarauder de nouveaux trous, si une modification doit être apportée dans le nombre et/ou dans la position des composants. Screwing the components onto the cooler leads to tapping holes in the cooler block, the number and position of which depend on the number of components and the arrangement provided for them. In addition to the need for a drilling and tapping operation for each component, this arrangement leads to immutability in the number and in the position of the components, which subsequently entails the obligation to drill and tap new holes, if a modification must be made in the number and / or in the position of the components.

L'invention écarte ces inconvénients: nécessité de percer et de tarauder les logements des composants dans le bloc support refroidisseur, et immuabilité du nombre et de la position des composants. The invention overcomes these drawbacks: need to drill and tap the housing of the components in the cooler support block, and immutability of the number and position of the components.

Elle a pour objet, à cet effet, un refroidisseur dans lequel le bloc servant de support aux composants électroniques de puissance comporte, sur au moins l'une de ses faces, au moins une gorge dont les deux faces opposées présentent de fines rainures qui, par coopération les unes avec les autres, constituent un filetage rectiligne s'étendant sur toute la longueur du refroidisseur et pouvant coopérer, en n'importe quelle zone, avec la tige filetée d'un ou de plusieurs composants.It has for its object, for this purpose, a cooler in which the block serving as support for the electronic power components comprises, on at least one of its faces, at least one groove, the two opposite faces of which have fine grooves which, by cooperation with each other, constitute a straight thread extending over the entire length of the cooler and capable of cooperating, in any zone, with the threaded rod of one or more components.

Suivant une autre caractéristique de ce refroidisseur, la ou les gorges prévues dans le bloc support pour recevoir les composants électroniques de puissance ont une profondeur supérieure à la longueur de la tige filetée du corps du composant électronique, de telle sorte qu'une circulation continue d'air peut s'effectuer non seulement lattera lement, mais aussi en dessous de la tige filetée. Le refroidissement du composant électronique est ainsi amélioré par rapport aux montages habituels, puisque la tige filetée du corps du composant ne se trouve plus emprisonnée dans un logement fermé. According to another characteristic of this cooler, the groove or grooves provided in the support block for receiving the electronic power components have a depth greater than the length of the threaded rod of the body of the electronic component, so that a continuous circulation d air can take place not only laterally, but also below the threaded rod. The cooling of the electronic component is thus improved compared to the usual assemblies, since the threaded rod of the body of the component is no longer trapped in a closed housing.

L'invention sera bien comprise d'ailleurs à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de ce refroidisseur pour composants électroniques de puissance :
Figure 1 est une vue partielle en perspective de ce refroidisseur,
Figure 2 en est, à plus grande échelle, une vue en coupe longitudinale suivant Il-Il de figure 1.The invention will moreover be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing representing, by way of nonlimiting example, an embodiment of this cooler for electronic power components:
FIG. 1 is a partial perspective view of this cooler,
Figure 2 is, on a larger scale, a longitudinal sectional view along line II-II of Figure 1.

Dans ce dessin, (1) désigne un bloc réalisé par filage en un alliage à base d'aluminium. Ce bloc (1) présente, venant de filage, non seulement les ailettes habituelles de refroidissement (2), mais aussi une gorge longitudinale (3) dont les deux - faces latérales présentent une pluralité de fines rainures (4). L'écartement et la profondeur de ces rainures (4) sont déterminés pour leur permettre de se comporter à la manière d'un filetage coopérant avec la tige filetée (5) qui prolonge vers le bas le corps (6) d'un composant électronique de puissance. In this drawing, (1) denotes a block produced by spinning from an aluminum-based alloy. This block (1) has, coming from the spinning, not only the usual cooling fins (2), but also a longitudinal groove (3) whose two side faces have a plurality of fine grooves (4). The spacing and depth of these grooves (4) are determined to allow them to behave in the manner of a thread cooperating with the threaded rod (5) which extends downwards the body (6) of an electronic component power.

La gorge (3) et ses fines rainures (4) peut en conséquence recevoir, dans n'importe quelle zone, un ou plusieurs composants électroniques. Cet agencement facilite considérablement le montage des composants électroniques sur le bloc refroidisseur (1) et permet à volonté de modifier le nombre et la position de ces composants sur ce bloc. The groove (3) and its fine grooves (4) can therefore receive, in any zone, one or more electronic components. This arrangement considerably facilitates the mounting of the electronic components on the cooler block (1) and allows at will to modify the number and the position of these components on this block.

Il s'agit là d'un premier avantage essentiel auquel s'ajoute un autre avantage résidant dans le fait que le rendement du refroidisseur est amélioré par rapport à la solution habituelle dans laquelle les composants électroniques sont vissés par leur tige filetée dans des trous taraudés dans le bloc support.This is a first essential advantage to which is added another advantage residing in the fact that the efficiency of the cooler is improved compared to the usual solution in which the electronic components are screwed by their threaded rod into threaded holes. in the support block.

Dans un refroidisseur conforme à l'invention, la tige filetée (5) du corps du composant électronique (6) n'est en effet pas emprisonnée dans un logement fermé; et de plus, la profondeur de la gorge (3) est supérieure à la longueur de la tige filetée (5) du composant (6). In a cooler according to the invention, the threaded rod (5) of the body of the electronic component (6) is in fact not trapped in a closed housing; and in addition, the depth of the groove (3) is greater than the length of the threaded rod (5) of the component (6).

Il en résulte que, comme le montre la figure 2, cette tige filetée (5) ne vient pas, par son extrémité inférieure, en contact avec le fond de la gorge (3) du bloc (1). Bien au contraire, un espace libre (7) se trouve ménagé entre le fond de la gorge et la tige filetée < 5). Cet espace (7) permet la libre circulation de l'air et donc facilite le refroidissement du composant électronique. As a result, as shown in FIG. 2, this threaded rod (5) does not come, by its lower end, into contact with the bottom of the groove (3) of the block (1). On the contrary, a free space (7) is provided between the bottom of the groove and the threaded rod <5). This space (7) allows the free circulation of air and therefore facilitates the cooling of the electronic component.

Comme il va de soi, l1invention ne se limite pas à la seule forme d'exécution de ce refroidisseur pour composants électroniques de puissance qui a été ci-dessus décrite à titre d'exemple; elle en embrasse, au contraire, toutes les variantes de réalisation.  It goes without saying that the invention is not limited to the sole embodiment of this cooler for electronic power components which has been described above by way of example; on the contrary, it embraces all of its variant embodiments.
