Abstract
A method for the efficient cooling of a cavity-bearing surface is disclosed. The method includes the provision of an extra-fine coolant mist to the surface to be cooled wherein the surface has at least two projections and at least one cavity therebetween. The mist is deposited so as to form an ultra-thin coolant film upon the surface and at least one coolant mist vortex within the cavity. The film is evaporated from its outside surface.
Claims12
A method for the cooling of a non-planar surface having at least one cavity which comprises:
- (a) contacting a mist to said surface at a droplet size, liquid mass concentration, velocity and direction to effectively provide a non-pulsed flow at said surface sufficient to form a coolant film on said surface such that at least one vortex is formed within said cavity and said film evaporates from an outside surface of the film thereby cooling said surface.
A method for the cooling of a non-planar surface having at least one cavity which comprises:
- (a) contacting a mist to said surface at a droplet size, liquid mass concentration and velocity sufficient to form a coolant film on said surface such that at least one vortex is formed within said cavity and said film evaporates from an outside surface of the film thereby cooling said surface;
- and
- wherein said mist consists of droplets ranging in size from about 18 to about 120 .mu.m.
