PURPOSE:To extremely reduce noise by using ion generating electrodes and a part of planar fins as ion suction electrodes, and accommodating both electrode groups within a wind tunnel, in the title hollow metal pipe type heat exchanger. CONSTITUTION:The planar fin groups 3-6 are so formed that they are concurrently used as ion suction electrodes corresponding to ion generating electrode groups 7 and 8. When a heat medium gas ionized by the electrodes 7 and 8 due to a corona discharge generated by a voltage applied across the electrodes, is sucked up to electrode plates 3 and 4, the heat medium gas comes into collision with even a heat medium which is not ionized yet and comes into collision with the electrode plates while moving the heat medium together, and rectified in the planar fin-groups 3-6, being injected through a blow-off port of a wind tunnel 9 while heat exchanging with the planar fin groups 3-6 as ion flow. Therefore, it is possible to reduce the noise and also to construct the heat exchanger in a compact form.
