"UN DISSIPATORE DI CALORE MODULARE PER DISPOSITIVI DI CONVERSIONE DI ENERGIA QUALI DIODI EMETTITORI DI LUCE A SEMICONDUTTORE (LED O LASER LED), CELLE FOTOVOLTAICHE A CONCENTRAZINOE, DISPOSITIVI AD EFFETTO SEEBECK O MICROMOTORI TERMICI"

The present invention concerns a heat sink (1) for semiconductor light emitters or for light absorbers and comprising: - A central portion (2) provided with attachment means (7, 8, 9) on which it is possible to fix the light emitter or the absorber and; - a plurality of tabs (3) that branches off from the central body and distanced between them so as to form a plurality of channels for the circulation of air. In accordance with the invention, the tabs (3) are arranged substantially parallel between them and at a reciprocal distance comprised within a range variable between 9 mm and 11 mm, in such a way as to optimize the passage of air for cooling. The heat sink (1) has an external overall shape in general parallelepiped-shaped, which favours the modular composition of two or more modular sinks (1) and the scalability with the least encumbrance.
