| 摘要 |
The invention relates to a recuperative countercurrent heat exchanger with high heat efficiency for two different media, in particular with such a short length in the flow directions of the media that the heat exchanger is at least mainly accommodated in a cavity in the frame of a window of the type in which air circulates within the glass panes in an essentially vertical path which passes through the heat exchanger. According to the invention, such a heat exchanger has been produced by constructing it from a stack of parallel plates 1, 2 made exclusively of plastic material with poor heat conductivity in the flow direction and designed with intermediate low distance members which delimit extremely narrow ducts 3, 4 on both sides of the plates for the two media. <IMAGE> |
