It is directly related to various subsequent production projects.
[0003] As electrical appliances become more and more intelligent, it is necessary to design a multi-layer printed circuit board to meet the circuit design requirements of the electrical appliances. However, in the prior art, multi-layer printed circuit boards are stacked, which is not conducive to heat dissipation. A multi-layer printed circuit board with fast heat dissipation is now proposed.

[0014] Beneficial Effects
[0015] The utility model provides a multi-layer printed circuit board with rapid heat dissipation, which has the following beneficial effects compared with the prior art:
[0016] 1. When the heat sink needs to be cooled, start the cooling fan. The wind head at one end of the air pipe absorbs the hot air inside the heat conduction groove formed by the four heat conduction plates. After being cooled by the cooling cylinder, the hot air is converted into cold air, and then blown to the inside of the heat sink from another wind head, thereby cooling the inside of the heat sink. At the same time, the fans inside the air holes on both sides of the heat sink rotate, and cooperate with the heat dissipation fins to further dissipate the heat inside the heat sink, thereby achieving the purpose of rapid heat dissipation.
[0017] 2. When multiple core boards have been working for too long inside the heat sink, they need to be replaced in time. Use the handle to drive the plug rod to pull out from the core board and the socket inside the placement hole. The push plate inside the placement slot pushes the core board out of the placement hole under the action of the spring, making it easy to take out. After taking out the new core board, push it into the heat sink along the slide rail. The socket of the core board and the socket of the placement hole are in the same vertical plane, and then insert the plug rod back. BRIEF DESCRIPTION OF THE DRAWINGS
