PURPOSE:To unnecessitate corrosion protective operation and cleaning for the subject device by providing net screens at a vent outlet of a ventilation frame provided with cooling tubes, causing dewed water to adhere onto the screens and exhausting water through an exhaust tube. CONSTITUTION:A number of cooling tubes 3 which pass therein a coolant are supported by fins 2, and accommodated in a ventilation frame 1. Two net screens 4 are arranged in an overlapped manner at the vent outlet of the ventilation frame 1. Further, each the of screens 4 is constituted by a wire material fabricated by coating an iron wire 5 with a vinyl tube 6 and a trough-like saucer 7 is provided at the lower part of each of the screens 4. An exhaust tube 8 leading dewed water collected in the saucer 7 to a predetermined position (not shown) for exhaustion is connected to the saucer 7. By this arrangement, it is possible to prevent intrusion of dewed water in an air supply casing, a blower and the like on the leeward. |
