Patent abstract

A housing in which a heat source for heating a member to be heated is disposable includes a first end and a second end in a longitudinal direction. Each of the first end and the second end is linked to a duct. A blowing unit is provided at the first end of the housing and causes an airflow in a space formed in a state in which the heat source is disposed in the housing. The duct linked to the second end of the housing is formed to extend from the second end. A length of the duct linked to the second end of the housing is longer than a hydraulic diameter by a predetermined number of times or more.
