PROBLEM TO BE SOLVED: To obtain a device capable of circulating air in an image forming device, so as to surely cool the air, with a simple constitution and at a low cost by providing an air flow passage, a fan for forcedly circulating the air, radiating plates and outdoor air fans for blowing outdoor air on the radiating plates. SOLUTION: The air after passing through the main body of the image forming device is discharged to the air flow passage by the fan and while the air passes through the divided flow passages 23 of the air flow passage, heat generated in the image forming device is radiated by the radiating plates 24. Then, the air is fed into the device main body from an intake by the fan of a discharge port and to the air flow passage from an exhaust port again, to repeat circulation. At this time, the outdoor air is taken in from an outdoor air intake by the outdoor air fans 25 and 26, blown on the surfaces of the radiating plates 24 and discharged from the exhaust port,, to prevent the rising of the temp. of the surfaces of the radiating plates 24. Thus, after the heat is radiated in the air flow passage, the flow of the air enters into the device again. |
