Specific embodiment
Below in conjunction with attached drawing, a kind of suitable high temperature and pressure heat exchange runner structure of the present invention is clearly and completely retouched
It states.
As shown in Figures 1 to 4, a kind of suitable high temperature and pressure heat exchange runner structure of the present invention, the structure include a runner
Plate, the runner plate are rectangular configuration, and the runner plate front surface is to face high fever plane of load, and the runner plate rear surface is along stream
The gusset of the multiple outwardly convexs of the parallel dense arrangement of guidance tape length direction, adjacent webs connect from beginning to end two-by-two, are formed concatenated U-shaped
Runner；
The small partition of protrusion is set on runner plate in the runner that gusset head and the tail junction is formed, and the small partition is ellipse
Cylindrical structure；Be arranged small partition purpose resist the thermal strain of gusset end, flow field end and it is small partition the distance between generally with
Runner root chamfer dimesion determines；
The depth-width ratio of the runner preferably 1.5；The gusset is thin-slab structure；
The permanent electrode in ITER, electrode surface will bear high thermal force, reach 350kW/m2, while will also bear neutron heat
Load, electrode surface using 4MPa 70 DEG C of the cooling water of high temperature and pressure cooled down, and these components regulation is born
30000 heat fatigue circulations.
Further, the length of the runner plate is respectively 350mm, 11mm and 15mm, and the runner plate thickness is most thin
Place is 6mm, and the runner plate forms 13 series connection runners, and gusset is with a thickness of 4mm；The material of the runner plate is 316LN-IG,
To guarantee compression strength and corrosion resistance.
As shown in Fig. 5 to Fig. 8, analyzed by calculating, 249.8 DEG C of electrode surface mean temperature, 293 DEG C of maximum temperature；It presses
30000 requirements are recycled according to ITER heat fatigue, total thermal strain is no more than 0.3%.Runner plate of the present invention faces high fever plane of load
