PROBLEM TO BE SOLVED: To provide a near infrared ray-irradiating drying device having a high drying speed, and capable of minimizing deterioration of a surface film of a heat exchanger as a product, miniaturizing the device, having high heating efficiency, and reducing initial running costs. SOLUTION: This near infrared ray-irradiating drying device comprises: a conveying device 3 for conveying the heat exchanger 13; a drying portion 5 comprising a near infrared ray irradiating means 11 for irradiating the near infrared ray to the heat exchanger; and an exhausting portion for discharging a steam component generated in drying the heat exchanger. Irradiation output of the near infrared ray irradiating means 11 is controlled by a control device 21. COPYRIGHT: (C)2009,JPO&INPIT
