Abstract (en)
[origin: EP0943876A1] The heater/cooler or pump has a heat exchanger, a tangential fan in a chamber (16) with a spiral outlet (15) and a porous deflector (10). The fan has no spiral projection (21) on its intake side, while its rotor blades (23) are inclined at an angle of over 50 degrees. Planes taken from the tip (20) of the deflector and the nearest point on the housing on the fan's intake side meet at an angle of over 180 degrees at the center of the rotor.
