1. A two-phase immersion-type heat dissipation structure having sheet-like heat dissipation fins, comprising:
a heat dissipation substrate, wherein a bottom surface of the heat dissipation substrate is in contact with a heating element immersed in a two-phase coolant;
a plurality of sheet-like heat dissipation fins, wherein a length of at least one of the plurality of sheet-like heat dissipation fins is from 50 mm to 120 mm, a width of at least one of the plurality of sheet-like heat dissipation fins is from 0.1 mm to 0.35 mm, and a height of at least one of the plurality of sheet-like heat dissipation fins is from 2 mm to 8 mm; and
a reinforcement structure being bonded to the heat dissipation substrate, so that a portion of the reinforcement structure protrudes from an upper surface of the heat dissipation substrate by between 2 mm and 20 mm;
wherein at least two adjacent ones of the plurality of sheet-like heat dissipation fins that are in parallel arrangement are spaced apart from each other by a distance that is from 0.05 mm to 0.5 mm;
wherein the plurality of sheet-like heat dissipation fins are integrally formed on the upper surface of the heat dissipation substrate, wherein an angle between at least one of the plurality of sheet-like heat dissipation fins and the upper surface of the heat dissipation substrate is from 60 degrees to 120 degrees;
wherein a material of the reinforcement structure is different from a material of the heat dissipation substrate;
wherein a Young's modulus of the reinforcement structure is greater than a Young's modulus of the heat dissipation substrate;
wherein the reinforcement structure is a reinforcement outer frame, an outer periphery of the heat dissipation substrate has an outer protruding portion protruding therefrom, and the outer protruding portion is embedded into an inner periphery of the reinforcement outer frame.
