<P>PROBLEM TO BE SOLVED: To restrain a large quantity of exhaust from a casing even when a large quantity of hot air is required for a large quantity of gas supply. <P>SOLUTION: A gas supply unit 100 includes a gas cylinder 2 filled with liquefied gas, a gas supply channel 11 for supplying gas discharged from the gas cylinder 2, an air introducing guide 3, and a hot-air circulation route 4. The hot air generated by a hot-air generator provided on the midway circulates in the hot-air circulation route 4. The air introducing guide 3 consists of a cylindrical shielding plate covering the gas cylinder 2 and includes a guide suction port into which the hot air from an outlet 4a of the hot-air circulation route 4 flows in and a guide outlet for discharging the hot air so as to be sucked to the suction port 4b of the hot-air circulation route 4. The hot air flowing from the guide suction port flows in a gap between the gas cylinder 2 and is discharged from the guide outlet. <P>COPYRIGHT: (C)2013,JPO&INPIT |
