  • Cold insulating chamber
    Patent number: 6698210
    Abstract: A cooler box includes a box member that has a hermetically closable cooling chamber formed inside it and that insulates heat and a cooling device that cools the interior of the cooling chamber. The cooling device is a Stirling-cycle refrigerator. Here, using a Stirling-cycle refrigerator as the cooling device helps realize a cooler box that can be operated from an easily available low-capacity, inexpensive power supply and that can cool a to-be-cooled article to a low temperature comparable with that produced by a freezer.
