Abstract: An inclined waved board and a heat exchanger thereof. The inclined waved board includes a board body composed of continuous waved sections. The waved sections are respectively inclined from a first side to a second side, and a third side and from a fourth side to the second side of the board body. The waved sections define multiple raised sections and recessed sections on two faces of the board body. The heat exchanger is composed of multiple board bodies arranged adjacent to and in parallel to each other. Each two adjacent board bodies define therebetween a flow way. The inclined waved sections enhance turbulence intensity and guide the fluids to produce secondary flows along the cross-sections of the flow ways to form dynamic three-dimensional swirling flow structures which combine to augment heat transfer rates with reduced pressure-drop.

Abstract: An inclined waved board and a heat exchanger thereof. The inclined waved board includes a board body composed of continuous waved sections. The waved sections are respectively inclined from a first side to a second side, inclined from the first side to a third side and inclined from a fourth side to the second side of the board body by an inclination. The waved sections define multiple raised sections and recessed sections on two faces of the board body. The heat exchanger is composed of multiple board bodies arranged adjacent to and in parallel to each other. Each two adjacent board bodies define therebetween a flow way. When fluids flow through the flow ways, the inclined waved sections enhance turbulence intensity and guide the fluids to produce secondary flows along the cross-sections of the flow ways so as to form dynamic three-dimensional swirling flow structure in the waved flow ways.
