<p>The exchanger (1) has fluid channels (12, 19) passed by respective fluid (24, 25). The fluid channels are designed in a spiral manner in opposite directions. Each channel lies against lower or upper wall of the other channel in each winding of a spiral unit (2) of the heat exchanger at an upper and lower wall in a laminar manner, where the spiral unit is formed by the channels. The channels exhibit rectangular flow cross section and are designed as a channel package. Ventilators (3, 4) are arranged at ends (5, 6) of the spiral unit, where the spiral unit is made of aluminum and plastic.</p> |
