Abstract
A cross flow heat transmitting device, comprising: (a) an exterior structural frame; (b) a multitude of channels formed of aluminum, each having an elongated straight section limited by side walls and edge walls, of a thickness of between 0.076 mm and 0.38 mm each and a ratio or ratio of aspect, length / width of an equivalent rectangle, equal to at least 4, being longitudinally aligned, in the relationship of parallel and spaced apart, each with a first fluid inlet opening at one of its ends and an opening first fluid outlet outlet at the opposite end, and common inlet manifold means and common outlet manifold means, respectively, for said first fluid inlet openings and said first fluid outlet openings, and there are a multitude of protruding wall parts formed from each side wall, distributed over the entire surface of the side wall and extending outward from it, with end bearing segments load bearing shaped to engage with and abut against load bearing end segments of said projecting portions of an adjacent channel side wall, thereby spacing adjacent channels at a distance, and bearing the outermost end segments against said frame external structural, to which they transmit the load of the channels, said wall protruding parts having a size and a mutual dimensional relationship defined by a dimension D approximately comprised between 5 and 25 mm, a dimension H approximately comprised between 0.5 and 3, 6 mm and a D/d ratio approximately between 3 and 18, where H is equal to the maximum height measured perpendicularly from a plane that contains the extremity of the extreme segment of the projection to a plane that contains the most distant point of said surface of side wall, D equals the effective separation distance between the centers of the protruding wall parts cont Iguines of a side wall, determined by the formula (see formula), in which D1 is the shortest distance between two adjacent wall boss parts in any triangular unit of the boss distribution design in the side wall, D2 is the perpendicular distance from a straight line that extends through the two contiguous wall boss centers cited to the center of the third wall boss of the same triangular unit, a triangle having a triangle having a wall boss center only at each of its vertices, each side of the triangle extending between wall boss centers without cutting or crossing a shorter line segment that interconnects other boss centers, and d equals the dimension of the relationship 4a/p, in which a is equal to the area of the load bearing end segment of the wall support ledge and p is equal to the perimeter of said carried end segment r load; and said projecting wall parts also having such a contour, in elevation or height, that the ratio θ/R is approximately between 1.6 and 1000 degrees per centimeter, with θ the maximum angle of the metal of the projecting part, with respect to the plane of the base of said lateral wall and measured in a straight section that passes through the center of the projecting part, perpendicular to the plane of the base, and R is the minimum radius of curvature of the metal, measured outside the protruding part; (c) said channels and projecting wall parts, as well as the external structural frame, being arranged and constructed to circulate a second fluid through said external structural frame normally to said channels and in the space between them, in heat exchange with said first fluid; and (d) at least one thin aluminum fin, of a thickness of between 0.076 and 0.38 mm, which extends at least outwardly from a channel edge wall along the entire length thereof, said fins being predicted in number and surface area with respect to the channel surface area such that the ratio or ratio (OC + OF)/IT, of the sum of the exterior surface area of the channel [OC] plus the outer fin surface area to said channels (0F), with respect to the total surface area of the interior of said channels (IT) is comprised between 1.2 and 4.0 and each fin having a multitude of surface deformations that start from the plane of the fin and enter the gap or space between adjacent fins of adjacent channels, and which are distributed at short intervals (S) between 0.25 and 5 mm, normally measured to the longitudinal axis of the channels, so that they constitute a total deformation area equivalent to at least 40% of said surface area fins, thus dislocating the circulation of the second fluid across the width of the fins.
