A bent pipe and a semiconductor refrigerator having the same are provided. The bent pipe for a fluid to flow therein includes a plurality of bent portions; a plurality of connecting pipe sections, each connecting two adjacent bent portions; and a retention member, which is successively fixed at different locations along the length thereof to the bent portions on the same side of the bent pipe. At least some of the pipe sections of the bent pipe can be kept in the bent shape by a retention member.

This invention relates to a portable temperature controlled container comprising a body having a storage compartment, an opening to permit access to the storage compartment and an insulated lid. The container comprises a fan, a heat sink and a first thermoelectric device, as well as a first phase change material and a second thermoelectric device in thermal communication with both the first phase change material and the storage compartment. The second thermoelectric device in thermal communication with both the first phase change material and the storage compartment is operable to transfer energy in the form of heat between the storage compartment and the first phase change material. The thermoelectric devices can be Peltier elements.

A system and/or method is provided that manages delivery of power for a device and an additional device. The system can include a device that consumes power to refrigerate an item stored therein, wherein the device includes an eutectic plate and an additional device that consumes power. The system can further include a power source that is configured to deliver power and a power manager component that is configured to monitor a temperature within the device. The power manager component can further be configured to activate the power source to deliver power to the device to reach a set temperature, switch the delivery of power from the device to the additional device based on the set temperature being reached, and maintain the set temperature in the device by switching delivery of power from the additional device to the device based on monitoring the temperature.

A portable container has a payload chamber for holding goods and a lid operable to access the payload chamber. The portable container also has an electronic system with one or more power storage devices, circuitry that wirelessly communicates via a cell radio with a cloud-based data storage system or a remote electronic device, and an electronic display screen. The electronic system also has a button or a touch screen configured to be actuated by a user to a) automatically switch sender and recipient information on the electronic display screen to facilitate return of the portable container to the sender or b) automatically contact a parcel carrier to alert the parcel carrier that the portable container is ready for pickup.
