Beschreibung
Zusammenfassung:	A double wall plate heat exchanger (100) comprising a plurality of double wall plate heat exchanger elements (110, 120) formed with a ridges (R) and grooves (G) providing contact points between neighbouring heat exchanger elements (110, 120) under formation of flow channels between them for fluids to exchange heat. The flow channels are in selective fluid communication with each other through port openings. Each of the heat exchanger elements (110, 120) comprises at least two joined plates and leakage channels are formed between the plates of each heat exchanger element (110, 120) for fluid leaking from a flow channel. The plates are provided with cooperating elevations (190) and indentations (200) forming leakage channels (210) extending across the ridges and grooves between the plates of each heat exchanger element (110, 120). At least one connecting space is formed between the plates to connect the leakage channels within the same heat exchanger element (110, 120), and each of the connecting spaces is connected to a leakage outlet.
