Heat exchangers are provided comprising plates of tubes (11) wherein the tubes (12, 13, 14, 15) are constrained supported and bonded in a parallel, essentially flat manner using a filament, thread, yarn or like material applied to the tubes (12, 13, 14, 15) in a weaving operation. Tubes (12, 13, 14, 15) are held together by weft threads (16, 17, 18). Using tubes as the warp, a woven structure is created with a thermoplastic thread as the weft. The direction of the heat exchange fluid outside the tubes (12, 13, 14, 15) is shown at 19, perpendicular to both the tubes and the weft. |
