The invention relates to a phase-change hot
pipe and liquid circulated cooling composite cooling device. The phase-change hot
pipe and liquid circulated cooling composite cooling device comprises a liquid circulated cooling
system and a phase-change hot
pipe cooling
system, wherein the liquid circulated cooling
system comprises a forced water-cooling circulation, automatic circulation oil-coolingor
forced circulation oil-cooling system, the phase-change hot pipe cooling system is a phase-change hot pipe, the liquid circulated cooling system and the phase-change hot pipe cooling system are simultaneously and integrally arranged, cooling fins are arranged on surfaces of the liquid circulated cooling system and the phase-change hot pipe cooling system, the phase-change hot pipe cooling system is heated to generate
phase change so as to dissipate hot of a hot source out, and meanwhile, heat of the liquid circulated cooling system is fully absorbed and is dissipated. The phase-change hot pipe and liquid circulated cooling composite cooling device has the advantages that the phase-change hot pipe and liquid circulated cooling composite cooling device is used for controlling temperaturerising of an ultra-
large capacity oil-immersed
transformer, the
oil temperature cooling capability is powerfully improved, the size of the
transformer oil-cooling system is greatly reduced, meanwhile,the
cooling effect of a
transformer winding is improved, and the phase-change hot pipe and liquid circulated cooling composite cooling device has positive significance in prolonging insulation
thermal aging lifetime of the transformer and improving the running load of the transformer.
