The invention discloses wavelength division multiplexing equipment comprising a wavelength division single board and a heat sink used for diffusing the wavelength division single board heat; the wavelength division single board comprises a single board body and a function device arranged on the single board body; the heat sink comprises a refrigerant channel used for circulating a refrigerant liquid and a groove used for containing the function device; the groove is arranged in a position, corresponding to the function device, on the outer surface of the heat sink, wherein the outer surface isfacing to the wavelength division single board; a gap coated by a heat conduction material is arranged between the groove and the function device; the refrigerant channel paves and extends in the heat sink, and is not connected with the groove. The wavelength division single board is covered by the heat sink, so the liquid cooling heat radiation using a conduction convection mode can replace an air-cooled heat radiation mode, thus greatly improving the heat radiation efficiency, and solving the problems that the air-cooled heat radiation mode is poor in heat radiation effect and large in noises.
Description
technical field [0001] The invention relates to the field of optical communication equipment, in particular to a wavelength division multiplexing equipment.
