  • Heat exchanger type fan
    Patent number: 6695038
    Abstract: Heat exchange devices are provided for use in ventilation and air conditioning systems where the heat carriers do not mix with one another. According to one embodiment, a heat exchanger type fan includes a casing having two inlets and two outlets, and a double-sided centrifugal impeller. The casing is divided into two isolated chambers, and the chambers together with the impeller form two isolated centrifugal fans. The impeller is made of a solid dividing disk, with backward curved blades located on both sides of the dividing disk, and intermediate blades placed between the backward curved blades and located over a periphery of the dividing disk. A ratio of a length of the backward curved blades to a distance between the intermediate blades over a mid-radius of the impeller is at least 10.
