Heat dissipating fin and heat sink

Abstract

A heat dissipating fin has a skirt having distal and proximal edges formed on at least one edge of the heat dissipating fin and multiple fastening components. Each fastening component is formed on the skirt and abuts the fringe of an adjacent the heat dissipating fin and has a hook and a hook mount. The hook is formed on and protrudes from the distal edge of the skirt. The hook mount is formed in the proximal edge of the skirt and corresponds to the hook. Since the hook is easily mounted through the hook mount the heat dissipating fins can be fabricated to form a heat sink easily to reduce manufacturing costs.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a heat dissipating fin, especially for a heat dissipating fin and heat sink formed therefrom to reduced manufacturing costs.

2. Description of the Prior Arts

With reference to FIG. 9, multiple heat dissipating fins (90) in accordance with the prior art are disposed in parallel and each heat dissipating fin (90) has two opposite edges and two pairs of fastening mounts (91). The pairs of fastening mounts (91) are respectively formed on and protrude perpendicularly from the opposite edges of the heat dissipating fin (90) and each fastening mount (91) has a protrusion (92) and a cavity (93). The protrusion (92) is formed on the fastening mount (91). The cavity (93) defining the fastening mount (91) corresponds and opposite to the protrusion (92) of the fastening mount (91). When the heat dissipating fins (90) are formed into a heat sink, the protrusion (92) of the fastening mount (91) of one heat dissipating fin (90) is mounted on a corresponding cavity (93) of the fastening mount (91) of an adjacent heat dissipating fin (90).

However, due to the protrusions (92) and cavities (93) of the fastening mount (91) are easily loosened so the heat dissipating fins (90) may be accidentally separated during production, transportation and distribution of the heat sink.

To overcome the shortcomings, the present invention provides a heat dissipating fin for a heat sink to mitigate or obviate the aforementioned problems.
