Liquid cooling optical module

The liquid cooling optical module comprises a PCB, a photoelectric device, a lens, an optical connector, a tube shell and a plastic packaging layer, the photoelectric device is arranged on the first side of the PCB, the lens is arranged on the photoelectric device, one end of the optical connector is in optical coupling connection with the lens, and the other end of the optical connector is in optical coupling connection with the tube shell. The plastic package layer is formed on the surface of the first side of the PCB in an injection molding mode, and the photoelectric device, the lens and one end, optically coupled with the lens, of the optical connector are jointly sealed between the plastic package layer and the surface of the first side of the PCB through the plastic package layer and the surface of the first side of the PCB, so that an integral plastic package module is formed. And the tube shell surrounds the outer part of the integral plastic package module. According to the liquid cooling optical mo
