Claim:
A sectional modular heat sink comprising a plurality of modular heat radiating units, each of the modular heat radiating units including: at least one pair of arm portions provided on a first plane of the modular heat radiating unit along a predetermined position, such that the two arm portions incline upward and outward; a substantially horizontal extended flange provided along a free edge of each of the arm portions; at least one substantially V-shaped channel provided on a second plane of the modular heat radiating unit opposite to the first plane to correspond to the at least one pair of arm portions; and a substantially horizontally extended groove provided along each of two innermost edges of the at least one V-shaped channel; whereby a plurality of the modular heat radiating units may be sequentially stacked and connected to one another to form the sectional modular heat sink through engagement of the at least one pair of arm portions and the flanges on a first modular heat radiating unit with the at least one channel and the grooves on a second modular heat radiating unit, respectively.
