Abstract
Structured boiling surfaces for increasing the critical heat flux of immersed surfaces are disclosed. The structures comprise holes or cavities in the boiling surface which constrain vapor jets to be less than the natural spacing thereof, which satisfy the vapor-liquid flooding criteria and which supply added surface area. A configuration having an arcuate surface in order to facilitate vapor removal therefrom when operated in a downwardly facing direction is disclosed.
