<p>The present invention relates to a heat transfer element comprising two opposed essentially rectangular plates (2, 4), joined together along essentially all sides (8, 10), but with channels between them for a flow of heat transfer medium. An essential feature of the invention is that the channels (14) of the element are tube-like and that the plates (2, 4) are attached to each other by seams (6), essentially parallel with the sides (8) of the plates.</p> |
