Description
Technical Field
The invention relates to equipment for heat exchange by applying a boiling phenomenon, which is mainly used for forming a metal frost structure on a boiling heat exchange surface so as to improve the boiling heat exchange performance of the surface of the equipment.
Background
Nucleate boiling can transmit larger heat flux density under smaller wall superheat degree, and is often used for cooling industrial equipment, such as nuclear reactors, electronic components, heat exchangers and the like. Particularly, in recent years, the electronic information industry has been rapidly developed, and in order to meet the demand, the density of electronic components has been continuously increased, and a large number of data centers have been built, which means that the heat dissipation demand of electronic devices has been increased. The heat dissipation requirement cannot be met only by air cooling, and the method for exchanging heat by liquid phase change can be presumed to become one of the mainstream of the future data center cooling technology.
In the nuclear boiling, there is a Critical Heat Flux (CHF), and when the Heat Flux of a device using the boiling phenomenon exceeds this value, the boiling state is transited from the nuclear boiling to the film boiling, and the surface temperature of the device rapidly rises, and the device is likely to be burned. Therefore, to improve the heat transfer characteristics of the equipment, it is necessary to improve nucleate boiling CHF.
Forming a porous structure on the boiling surface is one of the effective methods for elevating CHF. The frost layer formed by the condensation of the mixture of water vapor and air on the cold surface is a porous structure which has the promotion effect on the boiling heat exchange of an object in the liquid nitrogen of the low-temperature fluid. However, in general industrial application fields, the temperature range of boiling heat exchange is 100 ℃ to 300 ℃, and thus the frost layer structure formed by water is not suitable. Therefore, the low-melting-point metal is utilized to form the metal frost which is not easy to melt on the heat exchange surface of the boiling equipment, and the method has important meaning and practical value for improving the heat exchange effect of the boiling equipment.
