Abstract
A heat-wing includes: a sealed hollow chamber including two plates and a frame connecting the two plates; a capillary structure layer closely attached to an inner surface of the chamber; and a phase transition working medium sealed in the chamber. A portion of the frame or a portion of a periphery of one of the two plates serves as an evaporation area of the heat-wing, and the rest portion of the chamber serves as a condensation area of the heat-wing. The heat-wing has an increased vapor passage area, liquid working medium flow-back passage width and condenser heat transfer area and a reduced evaporator center-to-edge distance, and is hence capable of achieving a great improvement in heat transfer limit and heat flux density.
Claims17
A heat-wing comprising:
- a plate-shaped chamber formed by a first plate spaced from a second plate forming a condensation area having a length and a height, the first plate and the second plate connected together by a frame, the frame forming an evaporation area on a first end of the chamber between a first end of the first plate and a first end of the second plate, the evaporation area having a thickness defined as a distance between the first plate and the second plate, and an evaporation length defined as a length of the evaporation area, the evaporation length of the evaporation area within the chamber being greater than the thickness of the evaporation area by at least an order of magnitude, the frame sealing the first plate to the second plate thereby forming a sealed chamber having an enclosed and hollow space defined by the chamber on an inside of the first plate, the second plate, and the frame;
- a capillary structure layer within the chamber and adjacent inner surfaces of at least a part of the first plate and the second plate, the capillary structure layer further attached to an inner surface of at least a part of the frame;
- and
- a phase transition working medium sealed within the sealed chamber, the sealed chamber being evacuated;
- wherein the evaporation area is configured to be coupled with the evaporation length and its thickness in direct, planar, physical contact with a heat source;
- and
- wherein the condensation is configured to not be in direct physical contact with the heat source, and is configured to extend away from the heat source.
A heat-wing comprising:
- a chamber formed by a first condensation plate and a second condensation plate, the first condensation plate and the second condensation plate each having a length and a height and being positioned adjacent to each other, a first end of the first condensation plate and a first end of the second condensation plate are joined together by an evaporation area having a thickness extending between the first and second condensation plates along their respective lengths, the lengths of the respective first and second condensation plates defining the evaporation area within the chamber being greater than the thickness of the evaporation area by at least one order of magnitude, wherein other edges of the respective first and second condensation plates are joined together by chamber sides to form an evacuated, sealed, hollow chamber between the first and second condensation plates;
- a capillary structure layer and attached to the evaporation area within the chamber;
- and
- a phase transition working medium sealed within the chamber;
- wherein the evaporation area is configured to be coupled with its length and thickness in direct, planar, physical contact with a heat source at an area with a corresponding heat source length and thickness.
