Abstract:
A flat evaporator comprising:a substrate having on the top surface a vaporization cavity region with a central chamber in which main evaporation of a liquid coolant occurs, a capillary region surrounding the central chamber, and a manifold region surrounding the capillary region; a top plate disposed on the substrate; a capillarity generator which is formed in the capillary region and flows the liquid coolant from the manifold region into the vaporization cavity region by capillary action; an exhaust unit which includes a gas collector and exhausts a gas coolant generated in the vaporization cavity region; a plurality of adiabatic regions which divide a liquid coolant path in the manifold region into a plurality of flow paths and prevent heat from being transferred to the liquid coolant flowing along the plurality of flow paths; and a supplying unit including a coolant supply portion to supply the liquid coolant from the outside to the manifold region.
