摘要： The present invention relates to a sunlight-thermal energy conversion device capable of converting sunlight into thermal energy. More specifically, provided are a highly-efficient sunlight-thermal energy conversion device having a fine surface structure capable of significantly improving efficiency of sunlight -thermal energy conversion by maximizing absorption ratio of sunlight and accordingly maximizing boiling heat transfer efficiency to other heating media and a manufacturing method thereof. To that end, according to the present invention, the sunlight-thermal energy conversion device includes: a substrate which is made of semiconductor material; a plurality of first nano-wires which are extended upward in the vertical direction to the substrate, are arranged on the top surface of the substrate, and are made of semiconductor material; and a plurality of second nano-wires which are extended downward facing the first nano-wires, are arranged on the bottom surface of the substrate, and are made of semiconductor material. On the bottom surface of the space between the first nano-wires and the second nano-wires, metal particles are distributed in clusters.

摘要： PURPOSE: A heat transfer element and a manufacturing method thereof are provided to improve heat transfer performance by controlling film boiling by using a composite structure of a nanostructure and a microstructure and increasing a critical heat flux. CONSTITUTION: A resist layer is patterned on a substrate. The substrate is etched by a bosch process. A first structure(100) is formed by eliminating the resist layer. The first structure is formed on the substrate as a pattern. The first structure performs a role as a bubble seed. A second structure(200) is installed on the first structure. The second structure forms a super hydrophilic surface. A sidewall(300) surrounds the first structure. The size of the first structure is 1 to 10,000micrometers. The first structure is formed into a cavity or pillar shape.
