Abstract
A plate heat exchanger for exchanging heat between mediacomprises a number of stacked plates (A, B, C, D), the plates being provided with a first, large scale pressed pattern comprising ridges (R) and grooves (G) intended to keep first (A, B) and second (B,C) pairs of stacked plates on a distance from one another, such that flow channels for a first medium is formed in spaces between said plate pairs. Contact points are provided between the plate pairs in points where the large scale pressed pattern of neighboring plate pairs contact one another. The plates of each plate pair (A, B; C, D) are kept on a distance from one another by a small-scale pressed pattern comprising ridges (r) and grooves (g).
