HEAT EXCHANGER

摘要

A heat exchanger comprising a plurality of plates (10A) is described. The plurality of stackable plates (10A), when stacked one upon the other, from fluid channels between adjacent plates (10A) allowing heat exchange between fluid flowing on one side of a plate (10A) and fluid flowing on the other side of the same plate (10A), each plate (10A) comprising interengaging means (3A, 3B) on at least one pair of opposing edge regions (32, 34, 36, 38) for engaging with interengaging means (3A, 3B) on a corresponding pair of edge regions of a neighbouring plate (10A) to form seals between these edges (32, 34, 36, 38) when the plates (10A) are stacked together.
