Applications of Spray Cooling Technology in Aerospace Field

Abstract

Spray cooling is an effective heat transfer technology that uses liquid atomization and boiling to to take away the heat from the surface of a cooled object. It has the characteristics of large heat transfer coefficient, good temperature uniformity, small degree of superheat, high critical flux and small circulation flow. It has become a research hotspot of efficient heat and mass transfer technology. The electronic components in the aerospace field are generally in the harsh environment of high heat flux density, high vacuum, microgravity and high radiation. With the increasing use of high-power components in spacecraft, the heat dissipation of spacecraft has become the first problem to be solved in spacecraft design. In response to this problem, the author has studied a large number of spray cooling technologies for aerospace applications, and has certain application value for the research of heat dissipation of high heat flux components in aerospace field.
