Abstract (en)
Separation between adjacent edges of plates sandwiching corrugations made of at least 80% copper or at least 80% nickel, is 6-8 mm. Preferred features: Separation between the plates exceeds 10 mm. Corresponding cryogenic distillation plant, especially for air, is also claimed. The subject heat exchanger is the principal unit of its type, and is used to cool air to its distillation temperature. The heat exchanger is a sub-cooler. Corresponding air distillation plant includes a first, air-fed column, connected to a second column using a heat exchanger as described
Abstract (fr)
Un échangeur comprend plusieurs plaques (8) en cuivre, nickel ou aluminium ou un alliage de ces métaux séparés par des ondes d'échange en cuivre ou en un alliage de cuivre (6) et deux tôles extérieures (7). La séparation entre les plaques est supérieure à 6 mm, éventuellement 8mm. <IMAGE>
