<p>The air-air heat exchanger comprises two counter-flow air paths and a ventilator (12) conveying the opposing air currents. The air paths are arranged in a closed cylindrical housing (10), where the former air path runs in closed channels, while the latter air path is arranged in the space between the closed channels and the cylindrical housing. The ventilator is arranged at one end of the cylindrical housing.</p> |
