A device for cooling mixed air in a transfer pipe for a dust collector is provided to prevent mixed air comprising dust from flowing into the dust collector in a state that the mixed gas maintains a high temperature. A device(100) for cooling mixed air in a transfer pipe for a dust collector comprises: at least one cooling pipeline(110) which forms a portion of the transfer pipe in a state that the cooling pipeline is installed on a mixed air transfer pipeline for connecting a suction hood for sucking mixed air containing dusts in a heated state and a dust collector for collecting dusts in the mixed air; a plurality of cooling steel sheets(120) continuously disposed within the cooling pipeline with being spaced from one another in a predetermined distance and heat exchanged with the mixed air passing through the cooling pipeline; and a dust accumulation part(130) which is formed in a depressed form on a front lower portion of the cooling pipeline having the mixed air flown thereinto such that dusts contained in the mixed air are collided with the cooling steel sheets and dropped to be collected into the dust accumulation part.
