Abstract

La presente invención se refiere a dispositivo de transferencia de calor de aletas que proporciona transferencia de calor hacia y desde un tubo que contiene un fluido de transferencia de calor y comprende una cadena íntegramente formada por aletas conductoras de calor enredadas helicoidalmente en tensión alrededor de dicho tubo, dicha cadena comprende rebordes de montaje acomodados en contacto continuo con el tubo y las aletas están formadas íntegramente con lso rebordes de montaje y se extienden radialmente hacia afuera desde ahí, caracterizado proque los rebordes de montaje continuos comprenden dos espaciados axialmente, que se extienden helicoidalmente en paralelo, ambos están en contacto con el tubo; y adicionalmente porque cada aleta comprende dos patas formadas íntegramente con dos rebordes respectivos y un puente interconectado y formado íntegramente por dos patas respectivas, de forma que las patas y los rebordes de montaje están provistos en dimensiones previamente seleccionadas en relación unos con otros, para reducir substancialmente el puenteo de congelación entre las aletas adyacentes.The present invention relates to a finned heat transfer device that provides heat transfer to and from a tube containing a heat transfer fluid and comprises a chain consisting entirely of heat conducting fins wound helically in tension around said tube , said chain comprises mounting flanges arranged in continuous contact with the tube and the fins are integrally formed with the mounting flanges and extend radially outwards from there, characterized in that the continuous mounting flanges comprise two axially spaced, helically extending in parallel, both are in contact with the tube; and additionally because each fin comprises two legs formed entirely with two respective flanges and an interconnected bridge and formed entirely by two respective legs, so that the legs and mounting flanges are provided in dimensions previously selected in relation to each other, to reduce substantially freezing bridging between adjacent fins.
