ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a heat dissipating device more particularly to a heat dissipating device having an enhanced heat dissipating effect.
2. Description of the Related Art
Referring to
FIGS. 1 and 2
, a conventional heat dissipating device is shown to include a plurality of heat dissipating plates
10
which are disposed side by side. Each of the heat dissipating plates
10
has a stack plate portion
11
and a fin plate portion
12
that extends integrally from the stack plate portion
11
and that has a thickness smaller than that of the stack plate portion
11
. The stack plate portions
11
of the heat dissipating plates
10
are in close contact with one another, and cooperatively form a stack part
14
with a flat contact face to be placed in contact with a heat generating article
15
. The fin plate portions
12
of the heat dissipating plates cooperatively form a fin part
13
. Heat from the heat generating article
15
is essentially dissipated via the fin part
13
of the heat dissipating device. However, since the spacing between the fin plate portions
12
is relatively small, the heat dissipating effect is not satisfactory.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a heat dissipating device that has an enhanced heat dissipating effect.
According to one aspect of the present invention, a heat dissipating device comprises a plurality of heat dissipating plates. Each of the heat dissipating plates has a stack plate portion and at least one fin plate portion that extends integrally from the stack plate portion. The stack plate portions of the heat dissipating plates are in close contact with one another and cooperatively form a stack part with a flat contact face adapted to be placed on a heat generating article. The fin plate portions of the heat dissipating plates are bent from the stack plate portions to extend divergingly away from the stack part. The fin plate portions have confronting surfaces which diverge away from one another.
According to another aspect of the present invention, a heat dissipating device comprises a stack part and a plurality of fin plate portions. The stack part has a contact face adapted to be placed on a heat generating article. The stack part includes a plurality of stack plate portions which are placed in close contact with one another and which extend transversely of the contact face. The fin plate portions extend divergingly from the stack part and have confronting surfaces which diverge away from one another. At least every other one of the stack plate portions are connected to one of the fin plate portions. Each of the fin plate portions is bent from a corresponding one of the stack plate portions.
