technical field [0001] The invention relates to the technical field of heat dissipation, in particular to an active enhanced heat transfer device and an active enhanced heat transfer method. Background technique [0002] The development and utilization of energy has always been a research topic for the rapid development of human beings. With the gradual scarcity of non-renewable resources, countries around the world are actively exploring and developing new energy sources on the one hand, and on the other hand are actively studying ways and technologies to improve energy conversion efficiency. Among them, the breakthrough of enhanced boiling technology will greatly contribute to the effective utilization of energy in petrochemical, aerospace, microelectronic machinery and other fields, thereby improving energy utilization.

Problems solved by technology

[0004] At present, there are mainly two types of research on enhanced boiling heat transfer technology. One is to study the formation, growth, and desorption of single or small bubbles through experiments or numerical simulations. For example, some researchers use gas bubbling to force gas Artificial bubble disturbance is brought about by the heat exchange surface in the thermal boundary layer near the wall, but this method is not suitable for practical engineering applications; another research method is to conduct a large number of large-space nucleate boiling experiments based on practical applications to explore The influence of different factors on the effect of enhancing boiling heat transfer, but there are often two common difficulties in the boiling heat generation process of nucleate boiling experiments. The second is that the system is already in the stage of boiling heat transfer, but at this time, bubbles will merge to form a gas film, resulting in deterioration of heat transfer
