Assignee:

Marlow Industries, Inc. - Dallas TX

International Classification:

F25B 2102

US Classification:

62 36

Abstract:

A module for controlling the temperature within an enclosed structure is provided. The module comprises a thermoelectric assembly, a platform, and a panel. The thermoelectric assembly comprises a thermoelectric device with a first heat sink disposed on one side of the device and a second heat sink disposed on the other side of the device. The thermoelectric assembly further comprises an electric motor attached to one of the heat sinks with a rotating shaft extending longitudinally through the electrical motor and both heat sinks. A propeller may be attached to each end of the rotating shaft adjacent to the first heat sink and the second heat sink respectively. The platform may be removably engaged with the enclosed structure. A first fastener may be used to attach the thermoelectric assembly to the platform. A first opening may be provided in the platform adjacent to one of the propellers.

Abstract:

A transport apparatus, for hauling data storage media requiring environmental protection to and from a permanent storage site, includes a portable transport module and a transport cart. The transport module includes an insulated housing having guides for receiving shelves adapted to hold motion picture films, audio and video tapes, and photography film and provide ready access to and protection against movement during transit. A thermoelectric heat pump assembly heats or cools the interior of the insulated housing. A temperature sensor and a humidity sensor in the housing produce temperature and humidity measurement signals. Connectors are provided to connect power to the thermoelectric heat pump assembly and to output the temperature and humidity measuring signals. An ancillary power supply and control system are included to operate the transport module when separated from the transport cart. The transport cart has a platform with tie down cleats, wheels attached to the platform, wheel locks for securing the transport cart against rolling, a rechargeable battery power pack and compartment, connectors corresponding to the connectors of the transport module connect the rechargeable battery power pack to the thermoelectric heat pump assembly and receive the temperature and humidity measuring signals.
