Heat exchanger for a motor vehicle comprising flexible fluid lines and holding structure

Abstract

A heat exchanger for a motor vehicle includes first fluid lines of a flexible material, through which a first fluid (F 1 ) flows, and a holding structure with holding elements. The first fluid lines and the holding elements form a woven structure. The holding elements are in a thread-like manner and extend along a second direction of extension (R 2 ), at right angles to a first direction of extension (R 1 ). The heat exchanger, through which a second fluid (F 2 ) flows, is separated from the first fluid (F 1 ). The woven structure includes a first and second partial woven structures and are formed separately. The first partial woven structure and the second partial structure are arranged so that the second fluid (F 2 ) flows through the woven structure space, formed between the two partial woven structures. The first and the second partial woven structures are at an angle relative to one another.
