CPU cooling fin mounting device

The present invention relates to a CPU cooling fin fixing device.

Regular central processing unit (CPU) cooling fins are manufactured or equipped with hooks for fastening. As shown in Fig. 4, the cooling fin 3 is attached to the CPU 5 by hooking the hooks 1, 2 of the cooling fin 3 to the bottom wall of the CPU 5. Due to the arrangement of the hooks 1, 2, a gap (more than 1 mm in height) remains between the CPU 5 and the CPU holder 4. This gap reduces the connection area between the pins (not shown) of the CPU 5 and the CPU holder 4, and thus the bonding force between the CPU 5 and the CPU holder 4 becomes insufficient. When these CPU cooling fin fastening devices are used, the cooling fin 3 is attached to the CPU 5 by hooking the hooks 1, 2 to the bottom wall of the CPU 5.

timg is used to attach a cooling fin to the CPU of a vertical computer, the CPU holder can easily fall off the wiring.

The invention is therefore based on the object of providing a CPU cooling fin fastening device that eliminates the above-mentioned problems.

According to the invention, the object is achieved by the CPU cooling fin fastening device with a CPU holder for holding a CPU, the CPU holder having a plurality of protrusions on two opposite sides thereof, a cooling fin which is attached to the CPU holder in order to hold the CPU down, and two hanging devices which are pluggably connected to two opposite sides of the cooling fin and detachably hang on the protrusions in order to secure the cooling fin to the CPU holder.

It can be provided that the suspension devices are each made of a resilient wire bracket, each having two opposite hook-shaped ends which are rotatably hooked into respective hook holes on the cooling fin, curved wire bracket portions which are arranged on either side of the center and bridge the cooling fin, and a suspension wire bracket portion which is spaced between the curved wire bracket portions and hangs from the projections of the CPU holder.

Further features and advantages of the invention will become apparent from the following description, in which, with reference

Referring to the attached drawings, an embodiment is explained in detail. Here:

Fig. 1 is a perspective view of a CPU cooling fin attachment device according to the present invention;

Fig. 2 is an exploded view of the CPU cooling fin attachment device shown in Fig. 1;

Fig. 3 is a side view of the CPU cooling fin attachment device shown in Fig. 1; and

Fig. 4 is a cross-sectional view of a CPU cooling fin attachment device according to the prior art.

Referring to Figs. 1 and 2, a CPU cooling fin mounting device is generally provided with a first hanger 1 and a second hanger 2, which are pluggably connected to two opposite sides of a CPU cooling fin 3 for mounting the CPU cooling fin 3 to a CPU holder 4 without preload to hold a CPU 5 down on the CPU holder 4. Both hangers 1 and 2 are designed substantially identically. Therefore, only hanger 1 will be described in detail here. Hanger 1 is made of a resilient wire of substantially U-shaped configuration having two opposite hook-shaped ends 11, 21 each rotatably hooked into two opposite hook holes 31, 32 on the cooling fin 3, two curved wire bracket portions 13, 14 arranged on either side of the center, and a hanging wire bracket portion 12 arranged between the curved wire bracket portions 13, 14 for hanging on

projections 41 and 42 on the CPU holder 4.

Referring to Fig. 3, after the CPU 5 is attached to the top of the CPU holder 4, the cooling fin 3 is attached to the top of the CPU 5 and fixed in place to hold the CPU 5 in its down position by folding the hangers 1 and 2 over two opposite sides of the CPU holder 4 and hooking the hanging wire bracket portions 12 and 22 over the projections 41 and 42 on the CPU holder 4. After installation, the cooling fin 3 can be removed from the CPU holder 4 by pulling the hanging wire bracket portions 12 and 22 outward and then upward from the projections 41 and 42 of the CPU holder 4.
