PROBLEM TO BE SOLVED: To prevent trouble occurring in a vacuum generation device and to improve cooling capability by sufficiently separating moisture by condensing steam from suction air while minimizing an increase in a footprint, and thereby reducing the amount of moisture sent to the vacuum generation device 1.SOLUTION: A vacuum cooling apparatus includes a cooling tank 2 housing a body to be cooled and a vacuum generation device 1 sucking air in the cooling tank, and cools the body to be cooled by vacuumizing the cooling tank. The vacuum cooling apparatus further includes a plurality of heat exchangers 5 installed between the cooling tank 2 and vacuum generation device 1. In order that air sucked from the cooling tank 2 is cooled by upstream-side heat exchangers A, B and then cooled by a downstream-side heat exchanger C, the heat exchangers are connected in series, the upstream-side heat exchangers A, B are connected together so that the sucked air flows in parallel, and the downstream-side heat exchange
