CA 2658682

The invention relates to a heat exchanger structure that is substantially composed of a frame (2) inside which is arranged, parallel with each other, a plurality of radiating components (3) in which each radiating component (3) is composed of a pair of basic components (3a and 3b) coupled with each other symmetrically. The frame (2) is provided with at least one first cold liquid inlet duct (5) positioned below the base of the frame itself and at least one second hot liquid outlet duct (6) positioned above the top of the structure. In particular, each basic component (3a or 3b) is composed of a plate (30) with, on its inner side, a plurality of primary wings (31) spaced equally from each other and positioned orthogonally to the plate itself and on the outer side a series of secondary wings (32) which are also positioned orthogonally to the plate (30) and spaced equally from each other but closer to each other with respect to the primary wings (31). Besides, the plate (30) is equipped with two projections (30a and 30b) forming an arch, opposite each other and designed to couple with the corresponding projection present in the other basic component forming a channel (350).

La présente invention concerne la structure d'un échangeur de chaleur qui comprend sensiblement un châssis (2) dans lequel on dispose, en parallèle, une pluralité de composants de rayonnement (3) comprenant chacun (3) une paire de composants de base (3a et 3b) raccordés l'un à l'autre de manière symétrique. Le châssis (2) se compose d'au moins une première conduite d'amenée de liquide froid (5) disposée sous la base du châssis et d'au moins une seconde conduite de sortie de liquide chaud (6) disposée au-dessus de la partie supérieure de la structure. Chaque composant de base (3a ou 3b) possède en particulier une plaque (30) pourvue, sur sa face interne, d'une pluralité d'ailes primaires (31) équidistantes et disposées orthogonalement à la plaque, et sur sa face externe d'une série d'ailes secondaires (32) également agencées orthogonalement à la plaque (30) et équidistantes tout en étant toutefois plus proches les unes des autres par comparaison aux ailes primaires (31). En outre, la plaque (30) est équipée de deux saillies (30a et 30b) formant un arc, opposées l'une à l'autre et conçues pour se raccorder à la saillie correspondante présente sur l'autre composant de base formant un canal (350).
