Une extrémité de chaque plaque (18) est pourvue d'un rebord vertical (18c) et d'un prolongement (18d) s'étendant vers l'intérieur. Les rebords et les prolongements (18a, 18b), etc., servent d'éléments d'écartement de plaques. Des fentes (19, 20) et des extrémités dépourvues de rebords définissent des ouvertures pour des écoulements d'air (6 et 7). L'échangeur de chaleur (5), (ainsi que des aspects modifiés de celui-ci), est particulièrement destiné à des unités de ventilation par air, dont un certain nombre sont décrits et illustrés dans le descriptif.
