A heating surface, comprising:
- a plurality of protrusions;
- wherein an inter-protrusion gap and an interstitial space are formed between the plurality of protrusions;
- wherein a coolant vapor is formed within the inter-protrusion gap, driven toward the interstitial space, and drifts out from the interstitial space;
- wherein a first contact surface between the protrusions and a liquid coolant within the interstitial space is less than a second contact surface between the protrusions and the liquid coolant within the inter-protrusion gap;
- wherein the inter-protrusion gap or a serrated structure formed on the protrusions induces a capillary action interacting between the liquid coolant and the protrusions of the heating surface;
- wherein an adhesion between the liquid coolant and the protrusions drives the liquid coolant toward a bottom of the protrusions;
- wherein a cohesion of the liquid coolant drives the coolant vapor toward the interstitial space.
