<p>The plate heat exchanger assembly (10) has a flat metal material (30) with upper and lower plastics covers (20,50,60) forming channels between them. Intermediate seals (40) of thermoplastic elastomer seal the channels. The layers are held together by snap fasteners (26,66) through openings (36) in the flat material, which also compress the seals.</p> |
