Alveolar structure designed to cover a curved surface and its realization process

摘要

An alveolar structure for carrying hot or cold liquids which includes alveoles demarcated by several walls. At least one of the alveoles comprises at least one wall having at least two edges substantially parallel to each other and at least one wall comprising at least two edges not parallel to each other, with each of the substantially parallel or non-parallel to each other having an orthogonal projection length greater than zero and a line perpendicular to a surface to be covered by the alveolar structure through the edge in question.
