Title
(EN) HEAT-WING
(FR) AILETTE THERMIQUE
Abstract
(EN) A heat fin comprises two side panels, a frame for connecting the two side panels, a capillary structural layer, and a phase change working medium, wherein the two side panels and the frame form a hollow thin-plate casing; the capillary structural layer is closely attached to an inner wall of the casing; the phase change working medium is sealed in the casing; a part of an edge of each side panel or a part of the frame serves as an evaporation area; and the rest part of each side panel or the rest part of the casing serves as a condensation area. Due to the adoption of the heat fin, the area of a steam conveying passage, the reflux width of the liquid working medium, and the direct heat dissipation area of the condensation area are increased, the distance from the center of the evaporation area to the edge of the evaporation area is shortened, the heat conduction limit is greatly improved, and a higher heat flow density is obtained.
