Abstract (en)
[origin: EP0086175A2] Plastic double-walled sheets (1) are used in counterflow or cross-flow heat exchangers in order to guide stale air and fresh air. The double walled sheets (1) have a thickness of at most 15 mm, and the distance between two adjacent double walled sheets (1) in the heat exchanger is likewise at most 15 mm. The double-walled sheets (1) are thermostable and insensitive to cold. They are light and cost effective. The transfer of heat is as good as with the conventional heat exchanger plates. <IMAGE>
