| 摘要 |
The goal of this invention is to develop a counter (parallel) flow heat exchanger for ventilation systems that is effectively facilitating heat and moisture transfer from exhaust to intake air while suffering minimal deformations under influence of heat and humidity. The invention meets all three criteria by selecting plastic as the material for formation of corrugated layers (2) and paper or other moisture permeable material, for dividers (1) between the corrugated layers (2). Additionally, the corrugated layers (2) are formed with small bumps or barriers equalizing air flow across the whole cross-section of the heat exchanger. |
