Disclosed is a heat exchanger (1) composed of a stack of foils or plates (F), particularly a micro heat exchanger. Breakthroughs (4, 5, 7, 8) and ducts (2, 3) that extend on the level of the plate are configured in the individual plates (F). The plates (F) are placed on top of each other in such a way that the ducts (2, 3) intersect in successive plates (F), a first fluid (P) flows through the ducts (2) of one plate (F) while a second fluid (W) flows through the ducts (3) of the adjacent plate (F), feeding tubes and discharge tubes are embodied on the external faces of the resulting blocks of intersecting ducts (2, 3) by means of the breakthroughs (4, 5, 7, 8), and at least one of the two fluids (P, W) flows through the ducts of the respective plate antiparallel to one another or alternately in opposite directions.
L'invention concerne un échangeur de chaleur (1) composé d'une pile de feuilles ou de plaques (F), notamment un microéchangeur de chaleur. Des passages (4, 5, 7, 8) sont ménagés dans des plaques individuelles (F) et des canaux (2, 3) sont prévus dans le plan des plaques. Les plaques (F) sont disposées de manière superposée, de sorte que les canaux (2, 3) se croisent dans des plaques (F) successives. Un premier fluide (P) s'écoule à travers les canaux (2) d'une plaque (F) et un second fluide (W) s'écoule à travers les canaux (3) de la plaque (F) adjacente. Des conduites d'amenée et d'évacuation sont formées à travers les passages (4, 5, 6, 7, 8), sur les faces extérieures du bloc formé par les canaux (2, 3) qui se croisent. Au moins un des deux fluides (P, W) s'écoule de manière antiparallèle et alternée en sens inverse, à travers les canaux de la plaque concernée.
