In the discharge cell (30) of the second modification as shown in FIG. 5, a needle-shaped discharge electrode (31) is supported on one side of a support plate (33) having an "L"-shaped vertical cross section. The discharge electrode (31) is composed of a rod-shaped trunk and a conical protrusion formed at the tip of the trunk. On the other hand, the counter electrode (32) is arranged in the air passage (15) in a form substantially parallel to the discharge electrode (31). In addition, as in the above embodiment, the discharge electrode (31) and the counter electrode (32) are perpendicular to the air flow direction and are arranged along the air inflow surface of the heat exchanger (20) not shown. Furthermore, once a voltage is applied from the DC power supply (50) to the two electrodes (31, 32), the streamer discharge (60) is spread from the tip of the protrusion of the discharge electrode (31) to the counter electrode (32).

Example Embodiment
[0072]
The discharge unit (30) of the third modification shown in FIG. 6 is the same as the above-mentioned embodiment, and includes an insulating baffle (35), a discharge base (34), and a rod-shaped discharge electrode (31). On the other hand, in the third modification, the difference from the above-mentioned embodiment is that the plate-shaped counter electrode (32) is not provided, and the tip of the discharge electrode (31) faces the heat exchanger (20). The heat exchanger (20) is made of conductive aluminum as a main material, and is electrically connected to the negative side (grounded side) of the DC power supply (50). In addition, the heat exchanger (20) is configured to also serve as the counter electrode (32) of the above-mentioned embodiment. That is, once a voltage is applied from the DC power supply (50) to the discharge electrode (31) and the heat exchanger (20), the streamer discharge is spread from the tip of the rod-shaped discharge electrode (31) to the surface...
