Abstract
A two-phase immersion-type heat dissipation structure having acute-angle notched structures is provided. The two-phase immersion-type heat dissipation structure includes a heat dissipation substrate, and a plurality of fins. The heat dissipation substrate has a fin surface and a non-fin surface that face away from each other, the non-fin surface is configured to be in contact with a heat source immersed in a two-phase coolant, and the fin surface is connected with the fins. More than half of the fins are functional fins, and at least one side surface of each of the functional fins has first and second surfaces defined thereon and connected to each other. An angle between the first surface and the fin surface is from 80 degrees to 100 degrees, and an angle between the second surface and the fin surface is less than 75 degrees.
