Estimating the term…
The invention belongs to the technical field of phase-change heat transfer enhancement, and particularly discloses a multifunctional surface structure and a preparation method and use thereof for condensation enhancement. The multifunctional surface structure for condensation enhancement includes a copper substrate. A plurality of Tesla valve passages are parallelly arranged on a surface of the copper substrate. A diamond bump with a flared slope is arranged on the surface of the copper substrate between each side passage and the corresponding main passage. The surface of the copper substrate and surfaces of the diamond bumps and the Tesla valve passages are covered with a composite hydrophobic coating. The heat-transfer performance of the surface structure is remarkably improved.
A multifunctional surface structure for condensation enhancement, comprising a copper substrate, wherein a plurality of Tesla valve passages are parallelly arranged on a surface of the copper substrate, each said Tesla valve passage comprises a main passage and a plurality of side passages distributed on two sides of the main passage, a diamond bump with a flared slope is formed in the copper substrate between each said side passage and the corresponding main passage, and pointed ends of the diamond bumps are distributed to be parallel with at least a portion of a flow direction of the Tesla valve passages and at least one pointed end of the diamond bumps intersects at least one portion of the Tesla valve passages;
