Abstract:

Spray cooling has become an effective way to solve the heat dissipation problem of high-power electronic components due to its advantages of strong heat dissipation capacity, low working fluid consumption, and low contact thermal resistance. By summarizing the heat transfer enhancement mechanism of spray cooling, the challenges and bottlenecks currently faced by spray cooling technology, as well as the main development direction in the future, are pointed out. Firstly, the heat transfer mechanism of spray cooling is summarized. Compared with other cooling technologies, spray cooling with complicated heat transfer mechanism is more conducive to the heat dissipation of high-power electronic devices. Secondly, the latest experimental research progress of various strengthening means of spray cooling is introduced in detail, focusing on the working medium modification, surface treatment, spray parameters optimization and external physical field application. Then, the research status of novel electrospray cooling with a high-voltage electric field is introduced. Finally, the scientific challenges and technical bottlenecks of spray cooling technology in theoretical research and industrial application as well as the future direction of efforts are discussed.
