Embodiment Construction

[0016] Figure 1 to Figure 5 The heat sink fixing device 30 in the first embodiment of the present invention is disclosed, and the heat sink fixing device 30 is used for fixing the heat sink device 20 on the circuit board 10 to dissipate heat from the electronic components 12 mounted on the circuit board 10 . The circuit board 10 can be a graphics card, a video image card or a motherboard, etc., and the electronic components 12 mounted on it are high-power electronic components such as image processing chips, which will release a large amount of heat during operation. Four through-holes 14 for the radiator fixing device 30 are symmetrically opened around the electronic component 12 .

[0017] Such as figure 1 As shown, the heat dissipation device 20 includes a base 22, a plurality of heat dissipation fins 24 welded to the base 22, a fan 26 mounted on the base 22 and located on one side of the heat dissipation fins 24, and a cover disposed on the base The cover 21 on the cove...

Abstract

A heat sink fixing device is used to fix a heat sink on a circuit board, which includes a back plate installed on the back of the circuit board and a connecting rod that can connect the back plate to the heat sink. The rod includes a first end that can be clamped on the heat sink and a second end that can pass through the heat sink, the circuit board and the back plate in sequence, and the back plate is provided with a buckle line matched with the second end of the connecting rod. Let the fixing device cooperate with the buckle wire under the back plate through the connecting rod to fix the heat sink on the electronic components. The installation process does not require any relevant tools, which is simple, convenient, safe and reliable.

Description

technical field [0001] The invention relates to a fixing device, in particular to a radiator fixing device. Background technique [0002] With the continuous development of the computer industry, the operating frequency and speed of electronic components (especially chips installed on graphics cards and video image cards) continue to increase, and the heat generated is increasing. If not eliminated in time, the heat accumulation will cause the temperature to rise and affect Normal operation of heat-generating electronic components. [0003] Generally, the industry usually installs the heat sink on the electronic component through a fastener to assist in heat dissipation. Since the narrow space on both sides of the graphics card or video image card limits the size of the heat sink installed on it and the fastener used to fix the heat sink, the industry generally uses smaller screws to pass through the bottom plate of the heat sink. And the circuit board, cooperate with the ...
