A sectional modular heat sink is formed from a plurality of stacked modular heat radiating units, each of which is provided on one side along each longitudinal edge with an upright ridge portion having two inclined sidewalls, at least one of which being provided with a groove; and on an opposite side with a channel corresponding to the ridge portion to have two inclined sidewalls, at least one of which being provided with a flange corresponding to the groove on the ridge portion. A plurality of the modular heat radiating units may be sequentially stacked and connected through engagement of the ridge portions and the grooves on a first modular heat radiating unit with the channels and the flanges on a second modular heat radiating unit, respectively, and thereby form a sectional modular heat sink.

What is claimed is: 1. A sectional modular heat sink, comprising: a plurality of modular heat radiating units, each of the modular heat radiating units being provided on a first plane with at least one longitudinal edge with an upright ridge portion having flat ridge top and two sidewalls extending downwardly and outwardly from the flat ridge top; a second plane opposite to the first plane with a channel corresponding to the ridge portion, the channel having a flat top and two sidewalls extending downwardly and outwardly from the flat top having the same gradient as the two sidewalls of the ridge portion; 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 ridge portion on a first modular heat radiating unit with the channel on a second modular heat radiating unit; a groove located along at least one of the two sidewalls of the ridge portion, and a flange along at least one of the two sidewalls of the channel corresponding to the groove on the ridge portion, such that when the plurality of modular heat radiating units are stacked and connected to one another, the groove on a first modular heat radiating unit is engaged with the flange on a second modular heat radiating unit. 2. The sectional modular heat sink as claimed in claim 1, wherein at least one of the two sidewalls of the ridge portion is provided along a predetermined position with a flange, and at least one of the two sidewalls of the channel is provided along a predetermined position with a groove corresponding to the flange on the ridge portion, such that when the plurality of modular heat radiating units are stacked and connected to one another, the flange on a first modular heat radiating unit is engaged with the groove on a second modular heat radiating unit.
