PROBLEM TO BE SOLVED: To provide a cooler which can prevent the trouble in an after process by cooling enough sintered ore even in the case that the quantity of produced sintered ore increases. SOLUTION: This cooler has a hood for covering sintered ore shifting within the cooler itself, a heat exchanger for recovering the exhaust heat of hot blast recovered from the hood, a circulation pipe for circulating the hot blast at a relatively low temperature having its exhaust heat recovered to the downside of sintered ore under the hood, an outside air inlet for sucking outside air into the circulation pipe and mixing it with hot blast at a relatively low temperature, and a damper being arranged in a branch pipe for sending the cooling gas within the circulation pipe to an exhaust cylinder, being branched from the circulation pipe.
