Abstract (en)

[origin: WO8304432A1] A highly effective fin-type heat exchanger (A), which is easily reproduceable, versatile in application, low cost, comparatively compact, and light in weight. The construction provides for a low resistance to a flowing medium, by utilizing an array of highly heat conductive fins (3, 26), each fin (3) projecting in one continuous piece, through a partition (1, 23) of lower thermal conductivity, which separates two mediums. This intersection is sealed, to prevent cross-contamination between the two mediums. High thermal exchange ability is achieved by a configuration in which the flowing medium sequentially impacts the array of highly heat conductive fins (3), which extract the heat contained in this medium, and conduct the heat through the separating partition (1, 23), into the second medium. The apparatus and method have particular utility in a number of applications such as: waste heat recovery (Figs. 1-6, 9 and 12); water heaters (Fig. 8); a combination muffler and heater (Fig. 10); earth tubes (Fig. 7); solar thermal transfert (not shown); or numerous thermal dissipating applications, where the fins (3, 26) are either embedded into (Figs. 13 and 14) or project through (Fig. 11) a lesser conductive member (23, 28, 29), and extend outwardly into the ambient atmosphere.
