Claim:
1. A boiling section operable to boil a liquid phase refrigerant with heat from a heating element to change the liquid phase refrigerant in phase into a gaseous phase refrigerant, comprising: a comb-shaped structure having a bottom portion thermally connected to the heating element and a plurality of fins extending upward from the bottom portion; and a porous layer, provided on the bottom portion between the fins of the comb-shaped structure, comprising a number of fine particles and a hole between each fine particle, wherein each hole permeates liquid phase refrigerant to forcedly form a thin liquid film configured to receive transferred heat, wherein each of the plurality of fins have a length that is greater than a thickness of the porous layer, each of the plurality of fins have a thickness that is equal to or greater than a diameter of each hole, the thickness of the porous layer is equal to or greater than the diameter of each hole, and the diameter of each hole is equal to or greater than a diameter of a molecule in the liquid phase refrigerant and equal to or less than an interval between adjacent fins.
