Abstract (en)

[origin: WO0227255A1] The invention relates to a heat exchanger (1) for using in a ventilation device and for exchanging heat between two gaseous liquids which circulate according to the counter current principle. The inventive heat exchanger comprises hollow exchanger pipes (10) extending in the longitudinal direction, said pipes being open at the respective ends thereof and being enclosed by a housing (2). The housing comprises an inlet (11, 12) on the pipe-side ends thereof, and respectively comprises an outlet (5, 6) on a lateral surface near the respective ends. The exchanger pipes (10) are divided into partial sections (8, 9), the two gaseous liquids alternately flowing around and through said pipes.
