The heat exchanger has a set of plates (12) supported parallel to each other and spaced apart, between which air can flow. At right angles to the plates are elongated ducts or tubes (22) through which another medium such as hot air can be circulated, and which are spaced apart from top to bottom of the plates. Between each pair of ducts is a line of vertical slots (15) each slot having a baffle strip (16) attached, controlling flow through the slot into the adjacent space between the plates.
