BOILING ENHANCEMENT APPARATUS

Title:

BOILING ENHANCEMENT APPARATUS

Document Type and Number:

WIPO Patent Application WO/2020/155901

Kind Code:

A1

Abstract:

Disclosed is a boiling enhancement apparatus, comprising an evaporation chamber having a cavity therein and boiling enhancement fins. The boiling enhancement fins are provided on an inner wall surface of the evaporation chamber. A phase change heat transfer medium is provided in the evaporation chamber. The evaporation chamber absorbs heat of a heat source, and the heat is transferred to the phase change heat transfer medium by means of the inner wall surface. The boiling enhancement fins increase the number of vaporization cores at the inner wall of the evaporation chamber, and increase a boiling heat transfer area, thereby facilitating boiling vaporization of the phase change heat transfer medium and reducing boiling thermal resistance. In the boiling enhancement apparatus of the present invention, densely arranged boiling enhancement fins are used, thereby maximizing the heat transfer area and reducing boiling heat transfer thermal resistance. In addition, holes or windows densely arranged on the boiling enhancement fins greatly increase the number of bubble cores, reduce the diameter of the bubbles, and facilitate the formation of bubbles, thereby reducing the heat transfer thermal resistance.
