Abstract

A fastener which can be dismantled without tool is disclosed, which comprises an applied force generation mechanism, an automatic elastic ejection mechanism and a rotational linking mechanism. The applied force generation mechanism provides the pressure downward to tightly fix the heat sink onto the holding module. The automatic elastic ejecting mechanism provides the elastic force outward for the automatic ejection of fastener. The rotational linking structure is to moveably connect the applied force generation mechanism and automatic elastic ejection mechanism. When the first handle allocated in the applied force generation mechanism receives the first external force, it is escaped from the positioning hole through the rotational linking structure to pull the hooking member of the automatic elastic ejection mechanism.

571609 __Case No. 90127803_Yueyue Chromium _______ V. Description of the Invention (1) [Field of the Invention] The present invention relates to a heat dissipation device, and in particular to a heat dissipation device that can be disassembled without using tools. Device. [Background of the Invention] With the increase of the processing speed and efficiency of the Central Processing Unit (cpU), the current heat generation of the CPU increases,

The higher operating frequency will increase the wattage during operation. The high temperature generated will reduce the life of the CPU, especially when excessive heat cannot be effectively eliminated, which may easily cause system instability. In order to solve the problem of overheating of the CPU, a combination of a heat sink (h e a t s i n k) and a fan is generally used to remove heat in a strong cooling manner to maintain the normal operation of C p U.

The design of the sheet structure of the heat sink is used to increase the heat dissipation area and improve the heat dissipation effect. Therefore, the metal heat sink is heavy and large. Poor conditions affect the cooling performance, resulting in damage to the CPU, reducing system reliability, etc. Generally, buckling or locking the fixing screws is used to ensure stable contact between the CPU and the heat sink.

When considering the heat dissipation and heat sink fixing problems faced by the new-generation CPU, Intel designed a holding module on the motherboard of the Pentium 4 and fixed the heat sink to the holding module with a fastener to achieve better heat dissipation. effect. Please refer to Fig. 1 and Fig. 2. Fig. 1 shows a structural diagram of a conventional heat sink, and Fig. 2 shows a side view of the heat sink of Fig. 1. Cooling equipment
