Abstract
A heat exchanger cooling fin (401), for use in a fluid flow environment, comprising a fin plate (402) having a series of substantially mutually parallel louvres (403), each louvre (403) having a convex curved surface (404) facing in the opposite direction to each adjacent louvre (403), said series of louvres defining a nominal fluid flow path along the series over said convex curved surface (404) of each louvre (403).
Claims23
A heat exchanger cooling fin for use in a fluid flow environment, comprising a fin plate having a series of substantially mutually parallel louvres each louvre having two opposite open edges such that adjacent open edges of adjacent louvres define a flow aperture, each louvre having a convex curved surface that faces in the opposite direction to a convex curved surface of each adjacent louvre, said series of louvres defining a nominal fluid flow path along the series over said convex curved surface of each louvre
- wherein said louvres are arranged such that fluid flowing from a first side of said fin plate through a first flow aperture to the second side of the fin plate and over a first louvre, follows a curved contour of the convex surface of said first louvre through a second flow aperture to the first side of the fin plate and over the convex curved surface of a second louvre adjacent to said first louvre.
A heat exchanger comprising a cooling fin for use in a fluid flow environment, said cooling fin comprising a fin plate having a series of substantially mutually parallel louvres each louvre having two opposite open edges such that adjacent open edges of adjacent louvres define a flow aperture, each louvre having a convex curved surface that faces in the opposite direction to a convex curved surface of each adjacent louvre, said series of louvres defining a nominal fluid flow path along the series over said convex curved surface of each louvre,
- wherein said louvres are arranged such that fluid flowing from a first side of said fin plate through a first flow aperture to the second side of the fin plate and over a first louvre, follows a curved contour of the convex surface of said first louvre through a second flow aperture to the first side of the fin plate and over the convex curved surface of a second louvre adjacent to said first louvre.
A heat exchanger cooling fin for use in a fluid flow environment, comprising a fin plate having a series of substantially mutually parallel louvres each louvre having two straight edges and a convex surface curved from one such edge to the other and facing in the opposite direction to the convex curved surface of each adjacent louvre,
- wherein edges of adjacent louvres define a flow aperture of generally uniform width along said edges, said series of louvres defining a nominal flow path along the series over said convex curved surface of each louvre.
