PURPOSE: A vacuum molded article cooling apparatus is provided to secure the high cooling efficiency of a vacuum molded article by cooling compressed air in -5°C to 10°C by using antifreeze and a heat exchanging part. CONSTITUTION: A vacuum molded article cooling apparatus comprises a freezing unit(100), an antifreeze storing unit(200), a compressed air supplying unit(300), a heat exchange unit(400), and a jetting unit(500). The freezing unit comprises a compressor(120), a condenser(140), an expansion valve(160), and an evaporator(180). The condenser condenses the coolant compressed by the compressor. The expansion valve expands the condensed coolant. The evaporator evaporates and transfers the expanded coolant to the compressor. The antifreeze storing unit stores antifreeze cooled by the evaporator. The heat exchange unit cools the compressed air by the heat exchange with the antifreeze. The jetting unit jets the heat exchanged and cooled compressed air to a vacuum molded article. [Reference numerals] (AA) Vacuum chamber; (BB) Vacuum-formed object |
