ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a securing equipment for a heat dissipater of CPU, and more particularly, to one which can be secured to a holding member of the heat dissipater to fix the heat dissipater in position with ease and in such a way as to allow the heat dissipater to be mounted on the CPU with even pressure.
CPU would produce a large amount of heat when working, and the large amount of heat has to be dissipated, otherwise the CPU is likely to break down or get damaged. Therefore, a heat dissipating element is fitted onto the CPU to dissipate the heat produced by the CPU when the CPU is working.
Referring to
FIG. 5
, a conventional securing equipment for a heat dissipater of a CPU includes two securing elements
30
, each having a flexible elongated pressing part and connecting ends
301
and
302
at two ends of the elongated pressing part. The connecting ends
301
and
302
each has a hole
3011
and
3021
.
The heat dissipater
10
takes the form which has a base part
101
, and several radiating fins
102
spaced in the base part
101
. The heat dissipater
10
is provided with a holding member
40
, which is secured to the main holding board (not shown) of a computer and formed with securing protrusions
401
and
402
sticking out on two lateral edges thereof. An electric fan (not shown) is fitted adjacent to the heat dissipater
10
in the computer for dissipating the heat traveling through the radiating fins
102
. The heat dissipater
10
is mounted on the holding member
40
with the elongated pressing parts of the securing elements
30
being positioned on top of the radiating fins
102
and the connecting end holes
3011
and
3021
being connected to the securing protrusions
401
and
402
of the holding member
40
. Thus, the bottom of the heat dissipater
10
abuts the top of the CPU fitted to main holding board of the computer with a pressure so as to allow the heat of the CPU to pass through the fins
102
to be dissipated. Furthermore, heat dissipating ointment is applied over the top of the CPU for heat to travel to the heat dissipater with increased speed.
However, the securing element
30
is found to have the following drawbacks:
Firstly, the user of the computer has to remove the securing element by means of suitable tools such as screwdrivers for permitting the heat dissipater
10
and the CPU to be removed for maintenance, replacement, or upgrading thereof. Consequently, the securing element is likely to get deformed by the screwdrivers after many times of removals which are possible because computers are upgraded very frequently nowadays.
Secondly, the heat dissipating ointment applied over the top of the CPU would become unevenly distributed between the top of the CPU and the bottom of the heat dissipater because the securing elements are connected to the securing protrusions
401
of the holding member
40
from one end first and the other end after. Consequently, the effect of the ointment is reduced. In addition, the heat dissipater is likely to be mounted on the CPU with uneven: pressure due to a slight change in the shape of the connecting ends of the securing elements, reducing the speed of the heat of the CPU traveling to the heat dissipater.
SUMMARY OF THE INVENTION
Therefore, it is a main object of the present invention to provide a securing equipment for a heat dissipater of a CPU, which can be secured in position and removed from the secured position very easily, and which can help the heat dissipater to be mounted on the CPU with even pressure.
The securing equipment of the present invention includes a holed main body and a movable connecting element. The main body has downward-sticking connecting parts at a rear end, and is separably connected to the holding member of the heat dissipater with the connecting parts engaging rear securing holes of the holding member, the heat dissipater is positioned in the holding member with the bottom abutting the top of the CPU.
The movable element includes a control part, and a front connecting part having a pair of upward-sticking portions pivoted to an upper part of the control part. The control part is pivoted to the front of the main body from a lower part so as to be pivotable between a vertical locking position where the upward-sticking portions stand upright in a locking position and a substantially horizontal position where the upward-sticking portions is moved to a sloping unlocking position. Downwards-sticking hooked portions are formed on the front connecting part, and are fixedly connected to front securing holes of the holding member when the upper-sticking portions are pivoted to the locking position, so as to cause the main body to be pressed against the top of the heat dissipater. The main body is further provided with resilient pressing elements on the bottom; the pressing elements are constantly positioned in a horizontal position so as to not cause the heat dissipater to be pressed against the CPU with uneven force when the control part is pivoted from the unlocking position to the locking position.
