Abstract
A distribution apparatus, system and method for thermal control whereby a plate of a manifold assembly has predetermined surface features positioned on specific locations on a surface thereof for enhancing the cooling capabilities of the assembly. The predetermined surface features of the plate delay a velocity decay of a fluid impinging the surface of the plate, while also increase the surface area of the plate exposed to the impinging liquid, which in turn, maximize both the reliability and thermal performance of the overall thermal system at a given maximum operating pressure.
Claims20
A thermal distribution assembly comprising
- a plate having surface features residing on a surface thereof;
- an exposed surface area of said plate and said surface features;
- a manifold attached to said plate, said manifold having at least one microjet array and at least one distributed drain array;
- a cavity residing between said manifold and said exposed surface area;
- whereby said microjet array emits a fluid and said surface features of said plate delay a velocity decay of said fluid within a wall jet region of said cavity for enhancing thermal control of said assembly.
A system for thermal transfer comprising:
- a plate having a first surface and a second surface, said second surface having surface features residing thereon;
- a substrate having a temperature in need of modulating attached to said first surface of said plate;
- a manifold attached to said second surface of said plate, said manifold having a microjet array and at least one distributed drain array;
- a cavity residing between said manifold and said second surface of said plate having said surface features;
- whereby said microjet array emits a fluid into said cavity for contact with said second surface of said plate while said surface features on said second surface of said plate delay a velocity decay of said fluid for thermally controlling said temperature of said substrate.
A method for thermal control comprising:
- providing a plate;
- providing surface features on a surface of said plate;
- providing a manifold having a microjet array and at least one distributed drain array;
- forming an assembly by attaching said surface of said plate to said manifold such that said surface features avoid alignment with said microjets;
- emitting a fluid from said microjet array;
- contacting said fluid to said plate in locations of said surface area surrounded by said surface features, whereby said surface features delay a velocity decay of said fluid for enhancing thermal control of said assembly;
- and
- removing spent said fluid via said at least one distributed drain array.
