Title (EN) CATALYTIC STRUCTURES AND METHOD OF MANUFACTURE
(FR) STRUCTURES CATALYTIQUES ET PROCEDE DE FABRICATION DESDITES STRUCTURES
Abstract:
(EN) The present invention relates to the formation and use of catalytic materials as a part of or in association with heat exchangers such as automotive radiators and air conditioning condensers. The catalytic material involves a metal substrate with a porous anodic oxide coating and metallic nodules which are electrodeposited in the pores and extend above the surface of the anodic oxide coating. The nodules are either formed of the catalytic metal or formed of other metals and then coated with the catalyst metal. The catalytic stock material is then formed into heat exchanger fins and mounted on the heat exchanger tubes. In the alternative, the catalytic stock material may be formed into a separate catalytic structure which is then mounted in an air flow stream and preferably in air-flow relationship to the heat exchanger.
(FR) Préparation et utilisation de matériaux catalytiques constituant une partie d'échangeurs de chaleur ou en association avec ces derniers, tels que des radiateurs d'automobiles et des condensateurs de conditionnement d'air. Lesdits matériaux catalytiques comportent un substrat métallique couvert d'une couche d'oxyde anodique poreux et doté de nodules métalliques qui sont déposés par électrolyse dans les pores et s'étendent au-delà de la surface de la couche d'oxyde anodique. Les nodules sont soit constitués de matériau catalytique, soit constitués d'autres matériaux et ensuite couverts du métal catalyseur. Le matériau de départ catalytique est ensuite transformé en ailettes d'échange de chaleur et monté sur des tubes échangeurs de chaleur. Dans l'autre mode de réalisation, le matériau de départ catalytique peut être transformé en une structure catalytique séparée qui est ensuite montée dans un flux d'air et de préférence dans une relation de flux d'air avec l'échangeur de chaleur.
