Abstract

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.

Description

technical field [0001] The invention relates to a phase-change heat pipe and liquid circulation cooling compound heat dissipation device. Background technique [0002] In the current heat transfer and heat dissipation applications, liquid circulation cooling and heat dissipation by phase change heat pipes are designed for independent use. Especially for liquid circulation cooling and heat dissipation schemes, such as forced water cooling circulation, self-circulation oil cooling or forced circulation oil cooling system, etc. are set up in an independent working mode. When the liquid circulation cooling system fails or is out of operation based on special requirements, The corresponding system is bound to be forced to shut down, causing a lot of inconvenience. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a composite heat sink with phase change heat pipe and liquid circulation co...
