Abstract (en)
A heat exchanger includes a multiplicity of vertical, elongate, generally parallelapipedal boiling or mass transfer channels 4, each having a pair of main vertical walls defined by vertical plates 2 down which liquid is able in operation to flow. At least one of the channels 4 has at least one wave-shaped member or finning 14 dividing it into a multiplicity of vertical sub-channels 18. In addition at least one of the plates 2 has at least one vertical row of buffles or dimples 12 extending into at least of the sub-channels 18. Each baffle or dimple 12 engages finning 14 at both corner regions of a sub-channel 18 defined between a plate 2 and the finning 14. <IMAGE>
