Optical module with liquid cooling heat dissipation function and assembly method of sealing heat dissipation cover

The invention discloses an optical module with liquid cooling heat dissipation, which comprises an optical module, a sealing heat dissipation cover is arranged on an optical device arranged on a printed circuit board (PCB) in the optical module, a notch for leading out an internal optical fiber is formed in the sealing heat dissipation cover, and a liquid cooling agent is filled in a shell of the optical module. The invention further provides an assembling method of the sealing heat dissipation cover of the optical module with the liquid cooling heat dissipation function, glue is dispensed in the sealing groove of the sealing heat dissipation cover, and then the sealing groove is reversely buckled and bonded to the PCB. The optical module has the advantages that the sealing heat dissipation cover and the optical module with liquid cooling heat dissipation have a good heat dissipation effect, liquid leakage can be effectively prevented, the stability and reliability of the optical module are improved, and the
