ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a heat dissipating device, more particularly to a heat dissipating device for dissipating heat generated by a disk drive module inside a computer housing.

12
, a disk drive
17
and a fan unit
14
. The mounting frame
13
is mounted in a computer housing
11
of the computer device, has front and rear open ends

, top and bottom walls
121
,
123

121
of the drawer body
12
. The fan unit
14
is mounted removably on the front open end
161
of the drawer body
12
for generating air currents so as to carry away heat generated during operation of the disk drive

FIG. 2
illustrates a conventional array disk drive module

for a computer device, which is a modification of the abovementioned conventional disk drive module
1
. Unlike the abovementioned conventional disk drive module
1
, the conventional array disk drive module

15
′ of the mounting frame
13
′ and that are arranged in an array. Each of the drawer bodies
12
′ has a front open end, a bottom wall
123
′, and opposite lateral walls
122
′ connected to and cooperating with the bottom wall
123
′ so as to confine a receiving space
16
′. A plurality of disk drives
17
are mounted respectively in the receiving spaces
16
′ of the drawer bodies
12
′.
It is noted that, when heat is generated by the disk drives
17
in the conventional disk drive module

, the fan unit (not shown) is unable to dissipate heat effectively.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a heat dissipating device for dissipating heat generated by a disk drive module inside a computer housing with a relatively high heat-dissipating efficiency.
According to one aspect of the present invention, a heat dissipating device is adapted for dissipating heat generated by a disk drive module inside a computer housing. The disk drive module includes
a mounting frame mounted in the computer housing and formed with a slot,
a drawer body mounted removably in the slot and having front and rear open ends, top and bottom walls, and opposite lateral walls connected to and cooperating with the top and bottom walls so as to confine a receiving space that is accessible through one of the front and rear open ends, and
a disk drive mounted removably in the receiving space through said one of the front and rear open ends and mounted on the bottom wall of the drawer body.
The heat dissipating device is adapted to be disposed in the receiving space and comprises:
abase plate adapted to be mounted between the lateral walls of the drawer body, the base plate having a contacting surface adapted to contact and to be in thermal communication with the disk drive, and a connecting surface opposite to the contacting surface; and
a unitary heat-dissipating fin strip unit mounted fixedly on and in thermal communication with the connecting surface of the base plate, the fin strip unit including
a row of straight strip portions arranged along a first direction, each adjacent pair of the straight strip portions being spaced apart from each other so as to define a heat-dissipating space therebetween, and
a plurality of bridging units disposed respectively within the heat-dissipating spaces, each of the bridging units including a plurality of U-shaped strip portions, each of which has two ends that are connected respectively to corresponding ones of the straight strip portions, the U-shaped strip portions of each of the bridging units being disposed on one side of the corresponding ones of the straight strip portions and being arranged in a row along a second direction, which is transverse to the first direction.
According to another aspect of the present invention, a disk drive apparatus for a computer device comprises:
a mounting frame adapted to be mounted in a computer housing of the computer device and formed with a slot;
a drawer body mounted removably in the slot and having front and rear open ends, top and bottom walls, and opposite lateral walls connected to and cooperating with the top and bottom walls so as to confine a receiving space that is accessible through one of the front and rear open ends;
a disk drive mounted removably in the receiving space through said one of the front and rear open ends and mounted on the bottom wall of the drawer body; and
a heat dissipating device disposed in the receiving space and including
a base plate mounted between the lateral walls of the drawer body, the base plate having a contacting surface contacting and in thermal communication with the disk drive, and a connecting surface opposite to the contacting surface, and
a unitary heat-dissipating fin strip unit mounted fixedly on and in thermal communication with the connecting surface of the base plate, the fin strip unit including
a row of straight strip portions arranged along a first direction, each adjacent pair of the straight strip portions being spaced apart from each other so as to define a heat-dissipating space therebetween, and
a plurality of bridging units disposed respectively within the heat-dissipating spaces, each of the bridging units including a plurality of U-shaped strip portions, each of which has two ends that are connected respectively to corresponding ones of the straight strip portions, the U-shaped strip portions of each of the bridging units being disposed on one side of the corresponding ones of the straight strip portions and being arranged in a row along a second direction, which is transverse to the first direction.
