Optical fiber transmission mechanism and liquid cooling assembly

Abstract

The invention relates to an optical fiber transmission mechanism comprising a liquid cooling assembly and a light guide assembly penetrating through the liquid cooling assembly; the liquid cooling assembly comprises a main shell and an inner flow tube; a front cavity and a back cavity are formed in the main shell; a first through hole communicating with the front cavity and the back cavity is further formed in the main shell; a liquid inlet and a liquid outlet are formed in the main shell; the inner flow tube is contained in the back cavity; one end, close to the front cavity, of the inner flow tube is a cooling end, the cooling end of the inner flow tube is arranged corresponding to the first through hole; a flow guide groove is formed in the outer side of the inner flow tube, and the flow guide groove extends to the cooling end of the inner flow tube; a plurality of liquid through grooves are formed near the cooling end of the inner flow tube, and the liquid through grooves communicate with the first inner hole of the inner flow tube and the outer side of the inner flow tube; and the liquid through grooves are annularly distributed on the cooling end of the inner flow tube with acenter shaft of the inner flow tube as the center, so that the cooling liquid flowing into the main shell flows to a welding point from different direction with the welding point as the center underthe guide of the liquid through grooves, and the resultant force of the impulsive force applied to the welding point in the radial direction is close to zero.

Description

technical field [0001] The invention relates to the field of fiber laser technology, in particular to an optical fiber transmission mechanism and a liquid cooling component. Background technique [0002] With the development of high-power solid-state lasers, fiber lasers, and the continuous increase in the power of high-power semiconductor lasers, the heat dissipation requirements for fiber fusion points are also increasing. Because the common fiber fusion methods are thermal fusion, the optical fiber after thermal fusion can withstand A certain amount of axial tension, but it is difficult to withstand various forces in the radial direction. However, the daily cooling method of QD or QBH welding point is to use water flow cooling. However, the existing water flow cooling assembly does not guide the waterway and the corresponding water inlet pressure release device, in order to avoid radial impact on the stability of the welding point Therefore, the existing QD first-class p...
