Un dispositif de refroidissement de cellules solaires selon un mode de réalisation comprend : un substrat à rayonnement thermique fixé à une surface d'un module de cellules solaires; une pluralité d'ailettes de rayonnement thermique disposées sur le substrat de rayonnement thermique et espacées l'une de l'autre, chaque ailette de rayonnement thermique étant formée pour avoir une hauteur prédéterminée et s'étendre dans la direction longitudinale d'une longueur prédéterminée; et un couvercle qui entoure intégralement la totalité de la pluralité d'ailettes de rayonnement thermique de façon à former une pluralité d'entonnoirs conjointement avec le substrat à rayonnement thermique et chacune de la pluralité d'ailettes de rayonnement thermique, chaque entonnoir correspondant à une partie creuse s'étendant dans la direction longitudinale à l'intérieur du couvercle. Chacun de la pluralité d'entonnoirs comporte une ouverture d'admission et une ouverture d'échappement disposées à travers ses deux extrémités, respectivement, et a un passage d'air configuré comme un espace intérieur entre l'ouverture d'admission et l'ouverture d'échappement. De l'air extérieur est aspiré dans l'ouverture d'admission, passe à travers le passage d'air, et est évacué par l'ouverture d'échappement. Le passage d'air a un espace configuré de telle sorte que celui-ci devient progressivement plus étroit à mesure que la distance de l'ouverture d'admission vers l'ouverture d'échappement augmente. La vitesse d'écoulement de l'air extérieur, qui a été aspiré dans l'ouverture d'admission, est accélérée à mesure que celle-ci passe à travers le passage d'air.
