Specific embodiment
In the following with reference to the drawings and specific embodiments to ultra high power fiber coupler cooling module structure provided by the invention
It is described in detail.
As shown in Fig. 1-Fig. 2, ultra high power fiber coupler cooling module structure provided by the invention includes main structure 1
With auxiliary structure 2；Wherein main structure 1 is the L-shaped platy structure being made of vertical panel 3 and level board 4, the both sides position of vertical panel 3
Inlet opening 5 and an apopore 6 there are one being respectively formed；The surface middle part both sides position of level board 4 is recessed to be formed separately down
There are one inner groovy small stair 7, the position between two inner groovy small stairs 7 is U-shaped center inner groovy 8, and in U-shaped center
The depth of groove 8 is more than the depth of inner groovy small stair 7, and two of which inner groovy small stair 7 is respectively used to setting ultra high power
Input optical fibre 11 and output optical fibre 12 in fiber coupler cone；Auxiliary structure 2 is made of top surface 9 and three sides 10, rear end
