Heat exchanger and belt conveyor cooling mechanism and cooling machine using the same

摘要

PROBLEM TO BE SOLVED: To provide a chiller including a collision jet heat exchanger, generating cold air using this heat exchanger, and cooling a cooling target article.SOLUTION: A chiller configured to accommodate a belt conveyor mechanism, a heat exchange unit generating cold air, and a cold air ejection portion ejecting the cold air to a cooling target article as a jet to cool the cooling target article in a housing constituted by continuously connecting a plurality of cylindrical housing modules. The heat exchange unit includes: a pair of heat exchangers provided upright between both ends of the housing modules near both sides upward the belt conveyor mechanism; introduction fans 14 provided to set attraction directions thereof toward the respective heat exchangers; and ducts 15 interposed between the pair of heat exchangers and the fans of the introduction fans 14 arranged to face the heat exchangers and defining intake spaces from the heat exchangers to the fans 14.
