[0002] Circuit boards are divided into three major categories according to the number of layers: single-sided boards, double-sided boards, and multi-layer circuit boards. The first is single-sided boards. On the most basic PCB, parts are concentrated on one side and wires are concentrated on the other side. Because the wires only appear on one side, this type of PCB is called a single-sided circuit board. Single-sided boards are usually simple to make and low in cost, but their disadvantage is that they cannot be applied to products that are too complex.

[0003] After searching, a Chinese patent with announcement number CN214481433U discloses a circuit board with a heat sink, which uses two micro motors to drive two fan blades to rotate, so that the heat absorbed by the two sets of heat sinks is dissipated, and air is circulated through multiple heat dissipation holes on two support plates, thereby improving the heat dissipation efficiency of the circuit board. However, this device cannot quickly install the connecting frame according to circuit boards of different sizes, which easily leads to the heat dissipation mechanism being unable to be installed on circuit boards of different sizes, resulting in the heat dissipation mechanism being unable to play a heat dissipation role.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
