PURPOSE:To obtain the heat exchanger capable of obtaining heat exchanging effect without useless operation by controlling the blow-out direction of two fluids between which heat exchange is effected. CONSTITUTION:A plurality of guide vanes 14, for guiding blow-out fluid toward the opposite side of the fore blow-off port of secondary fluid N, which is neighboring to the fore blow-off port in a space 12 through a plate 8 at the discharging side of the secondary fluid N, for example, are arranged from the side of an outside control body 10 toward the inside of the device with predetermined spaces in the fore blow-off port of the space 12 of respective heat exchanging elements 9, passing primary fluid M at the air supplying side and having no fin 7. According to this constitution, heat exchanging operation may be effected efficiently without causing mixing effect at the vicinity of the blow-off ports between the primary fluid M and the secondary fluid N, which are blown out of the fore blow-off ports (a), (b) respectively. On the other hand, the primary fluid may be supplied into a predetermined direction smoothly. |
