Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a CPU heat sink.

[0002]

[Prior art]

 At present, the CPU generates high heat during the execution of calculations, so it is important to extract and dissipate the heat, which allows the CPU to execute calculations in a normal temperature environment and maintain a stable work environment. Generally, the heat dissipation work of the CPU is generally performed by an air cooling device.

As shown in FIG. 5, the main structure of the air-cooling device includes a heat sink 10 and an air-cooling fan (not shown). The heat sink 10 has a plurality of air cooling fins 102 connected to a bottom seat 101, and an air cooling fan fixedly provided above the heat sink 10. Both ends of the hanging part 30 extend vertically downward and the hanging part is formed. 301 and 302 are formed, and two hanging portions 301 and 302 are provided with hanging holes 3011 and 3021. At the same time, convex pieces 401 and 402 are provided on both sides of the heat sink receiving seat 40 provided above the CPU. The hanging holes 3011 and 3021 of the hanging part 30 engage with it. In this case, the heat sink 10 provided with the air-cooling fan is closely attached to the CPU on the bottom surface of the bottom seat 101, and the hanging portion 301 at one end of the hanging component 30 is firstly inserted into the hanging hole 3011, and the convex portion at one end of the heat sink receiving seat 40 is formed. Hook 401, and the hook 302 of the other end of the hook part 30 is pressed down, and the hook hole 3021 of the hook 302 is hooked on the convex piece 402 on the other side of the heat sink receiving seat 40. As a result, the hanging component 30 continuously applies pressure to the heat sink 10, and the heat sink 10 and the air-cooling fan are simultaneously stably fixed and pressed to the CPU, and the CPU generates high heat generated during the calculation by the air-cooling fin 102 of the heat sink 10. The air-cooling fan blows air to the air-cooling fins 102 to discharge high heat and dissipate heat.

[0004]

[Problems to be solved by the invention]

 However, the above-described air cooling device has the following disadvantages. (1) Since it is becoming increasingly popular to assemble and upgrade personal computers, disassembling and assembling the heat sink and CPU is performed more frequently.However, when removing the hanging pieces, use a tool such as a flat screwdriver. The hanging part can only be taken out of the heat sink seat by lifting the fixing piece on one side of the hanging part using the And often causes difficulties for users.

[0005] (2) Since the hooking parts are located on both sides of the heat sink, when the hooking parts hang on the heat sink receiving seat, the hooking parts on one side are first pushed, and then the hooking parts on the other side are pushed. In the process of pushing, the heat dissipating gel applied between the heat sink and the CPU is subjected to non-uniform force by the hook pieces that are engaged in the front and back, and the heat dissipating gel is distributed on the bottom surface of the heat sink on average. If the hanging force of the hanging parts on both sides of the heat sink is not uniform, the bottom surface of the heat sink cannot be in close contact with the CPU, so that the heat spreading effect is significantly reduced.

The present invention has been made to eliminate these drawbacks by devising many years of design and manufacturing experience by the present inventors. SUMMARY OF THE INVENTION An object of the present invention is to provide a CPU heat sink which can be easily assembled and disassembled, and can be installed in close contact with a CPU.
