Boiling two-phase phenomenon is one of effective methods, and it has high ability to remove and transport waste heat. The technology can be applied to the cooling systems also in space. Experiments on the increase in CHF for flow boiling in narrow channels by improved liquid supply were conducted for the development of high-performance space cold plates. A structure of narrow heated channel between parallel plates with an unheated auxiliary channel was devised and tested by using water for different combinations of gap sizes and volumetric flow rates. Five different liquid supply modes were compared. CHF values lager than 2 x 10(exp 6) W/sq m were obtained for the improved heat transfer structure with a heated length of 150 mm. Under several conditions for gap size of 2 mm, the extensions of dry-patches are observed at the upstream position of the main heated channel resulting burnout not at the downstream but at the upstream. It was clarified that there is an optimum flow rate allocation for both channels to obtain the highest values of CHF., 資料番号: AA0064297119}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {狭あい流路内強制流動沸騰を利用した宇宙用高効率冷却システムの開発}, volume = {25}, year = {2009} }
