AI Technical Summary

Technical Problem

In the existing technology, the way the cooling fan on the motherboard is fixed requires multiple screws, which can easily cause the motherboard to bend. In addition, the space above the CPU is limited, resulting in poor heat dissipation and inability to effectively dissipate heat from other components.

Method used

The heatsink is fixed to the CPU position above the motherboard using a mounting bracket. The cooling fan is secured using the side wing of the mounting bracket, requiring only two connecting bolts. Combined with heatsink fins and airflow deflectors, this enhances heat dissipation and reduces the risk of motherboard bending.

Benefits of technology

It improves the heat dissipation of the CPU and other components on the motherboard, reduces the risk of motherboard bending, and achieves a more efficient way to fix the cooling fan.

Abstract

The utility model discloses a mainboard of integrated AV output, including mainboard, the top of mainboard is provided with CPU, USB interface, optical fiber interface, HDMI interface, composite video interface, first audio interface and second audio interface, CPU's both sides are provided with mounting piece, the mounting piece includes a horizontal part and two side wing parts, the first bolt is screw -threadedly installed on the horizontal part, the horizontal part is screw -threadedly connected with the mainboard through first bolt, be provided with the heat dissipation subassembly on the mounting piece. The utility model discloses the heat dissipation subassembly is installed in the position of CPU above the mainboard through mounting piece, and the side wing part of mounting piece both ends is used for fixing heat dissipation subassembly, so that the heat dissipation wind that heat dissipation fan blows can flow from the air around heat dissipation fan and CPU, increase its heat dissipation effect, and two mounting pieces only need two connecting bolts to realize the fixation of heat dissipation fan, compared with traditional connection mode, this installation mode can reduce the risk of bending to mainboard.
