ABSTRACT:
A plate-type heat exchanger comprises a stack of plates each of which comprises in a first direction a first end portion, a heat exchanger surface and a second end portion. In each end portion there are at least two parallel rows of openings namely one row of openings for one flow and another row of openings for another fluid. These rows are substantially parallel to each other and extend substantially perpendicular to said first direction. Thus, in each space between adjacent plates, one flow will pass between the screens which connect the spaces adjacent said space, wherein a pure counterflow heat exchange is provided for the heat exchanger.
