Corrugated fin for heat exchanger e.g. vaporizer-condenser, has pores, and corrugations, each including vertical legs alternatively connected by top and base of corrugation, where top, base and legs are made of sintered aluminum particles

摘要

The fin has multiple pores, and multiple corrugations, each including a pair of vertical legs (123) alternatively connected by a top (121) and a base (122) of the corrugation. The top, base and legs are made of sintered aluminum particles. The legs, tops and bases form rectilinear segments in a section transversal with respect to main corrugation direction (D1). The tops and the bases are parallel to each other. An independent claim is also included for a cryogenic air separation unit comprising a vaporizer-condenser that has fins.
