Advantageous devtoeonreats of toe imtoution are set ©to to the dependent claims. 4, Summán/ offne invention fOOOől Within the meaning of the invention, the sub-modules are disposed verikaiiy and normal to the longitudinal: direction of the collectors, wherein the pipes of the sub-modules for toe air passage are disposed as parallel with a spacing írom one another. À cooling radiator is tous created which, comprising a plurality of cooling elements following beside or behind one another to a row ar:d with an air gap relative to cute another, inserted to apertures of the upper collector pipe and toe lower collector pipe, permits a particularly good air passage test# toe cooling radiator overall and at toe respecti ve codling elements, fOiÜlf All toe éeö&jg Äas cohtÄtei ptufebiy equally, to the heat tftoís^r ftoto toe cooing medium, pÄÄy ©I, flowing through: the to the ambient air iowtog: through fee eorifeg radfetOc, Apa. tusuk, a pameaiarîy high energy dissipation dhup feJtjd kWÄ* jpsÉn&y ο#'©ρ· î© dfeSfekWfe, rs ashieveil wife, a cooling radiator with a width of up to 548 iras, pmfeîPbiy tip 1# SM mm, and à height of up to t fe* Ρ$ΦχΦΜ Wt0 1.88¾ A ¢00¾ radufeA wife a height of 8,5 m up to; %$. m is preferred With optimised ofess-secíkms boti? of the upper and the fewer collector and of the pipes: of fee respective sub-•noduks, a Slow rare of oh through the eooiing radiator of up to 2?08 kg/h, preferably op to 2880 kg/h can he achieved.
[0008] As has been confsrmed by tests, the liquid, in particular oil, flowing through the pipes from top to bottom wife the best codling effect e^eiesees fee least resistance wfe an optimised emss-seedon of fee cooling ekmenls of the cooling radiator is observed. Since only the kast possible resistances occur, the system cat? öpsrätö ΐτδ^ convection; no pumps are required.
[0009] The eooihxg radiator is thus present as a eoutpacl complete unit, which comprises as many sstbonodules as desired, disposed spaced apart feem orte another and oonsected via the indlÄtal distributor pipes to fee collectors. The amblefe aife rfinsed be assisted: by fensfeanlilafers, is able to flow eruapletely around fee entire eooiing f aiiator and: ife fethfeiodhles both in fee transverse and also in fee longitudinal direction.
