A plastic tube heat exchanger suitable for refrigerant use is provided by wrapping a layer of tubes (10) around a curved surface (12), on a base (11) which is generally perpendicular to the surface (12). Several to many tubes (10) can be in each layer. Then, further layers can be wrapped continuously by overlaying the first layer. Heat exchangers, including refrigerant apparatus, condensers and evaporators, can be made in this configuration. Processes and articles of manufacture are parts of the invention.
Cette invention a trait à un échangeur de chaleur, sous forme de tuyauterie en matière plastique, pouvant servir de refroidisseur, lequel échangeur de chaleur est formé par enroulement d'une couche de tuyaux autour d'une surface courbe, sur une base généralement perpendiculaire à cette surface. Chaque couche peut comporter quelques tuyaux sinon un grand nombre. Il est ensuite possible d'enrouler d'autres couches se superposant à la première. Il est possible de fabriquer des échangeurs de chaleur, y compris des appareils de refroidissement, des condenseurs et des évaporateurs, ayant cette configuration. L'invention concerne également des procédés et des articles fabriqués selon ces procédés.
