ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a fixing frame having two lugs extending from an outer surface thereof so as to retain a securing belt during assembling.
BACKGROUND OF THE INVENTION
A conventional heat dispensing device for computers is shown in
FIGS. 1 and 2
and generally includes a base from which two groups of fins
30
extend, a slot defined between the two groups o fins
30
. A fixing frame
20
is fixedly mounted onto the base by bolts
60
and two notches
210
are defined in two opposite walls
21
of the fixing frame
20
. A fan
10
is connected to a top of the frame
20
by bolts
50
and located above the fins
30
so as to send heat out from the fins
30
during operation of CPU of computers. A securing belt
40
has a first end
41
with a hole
410
which is hooked on a hook
71
on a side of a slot frame
70
on the board of computers as shown in
FIGS. 3A and 3B
. The belt
40
extends through the notches
210
and the slot between the two groups of fins
30
and a second end
42
of the belt
40
has another hole
420
which is to be hooked to another hook
72
on the other side of the slot frame
70
. However, during assembling, the assembler has to press the first end
41
of the belt
40
to keep the first end
41
hooking to the hook
71
. A tool is used to press a protrusion
43
on the belt
40
and to guide the hole
420
in the second end
42
of the belt
40
to be hooked with the hook
72
. It takes a lot of time to hook the two hooks
71
,
72
with the two holes
410
,
420
. The first end
41
could disengage from the hook
71
during assembling and/or by an impact.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a heat dispensing device for computers and the device comprises a base with fins extending therefrom and a slot is defined between the fins. A fixing frame is mounted on the base and two notches are defined through two opposite walls of the fixing frame. A retaining device extends from one of the two opposite walls. A fan is fixed to a top of the fixing frame and located above the fins. A belt extending through the two notches and the slot has a first end and a second end. A section adjacent the first end of the belt is retained in the retaining device and the first end is engaged with a hook on a board. The second end of the belt is engaged with another hook on the board.
The primary object of the present invention is to provide a retaining device on the fixing frame so as to retain the first end of the belt such that the first end of the belt is well positioned during assembling.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
