Further, the small refrigerator includes a duct cover disposed inside the Peltier and having a return portion and top and bottom outlet portions formed on top and bottom thereof to exhaust the cold air generated through the heat exchange with the heat absorber of the Peltier from the return portion to the upper and lower portions of the storage space.

Apparatus for controlling the temperature of a beverage container, for example, by either chilling the beverage container or maintaining the beverage container at a predetermined temperature, the apparatus having a generally cylindrical configuration with a receptacle in its upper portion and cooling components in the lower portion to establish a low center of gravity for the apparatus.

A storage system for a house entrance includes an entrance refrigerator, a first storage disposed above the entrance refrigerator, and a second storage disposed below the entrance refrigerator.

A Peltier module or device with at least one Peltier element with a first surface and an oppositely located second surface, wherein on the first surface a first heat transfer element of an air duct is disposed, wherein the air duct, for the conduction of air along the first heat transfer element, comprises an input opening, in which a ventilator is disposed, and an output opening and wherein on the second surface a second heat transfer element of a cooling body is disposed, wherein the ventilator is developed and disposed such that an air flow generated by the ventilator forms with the first surface an angle (α) between 10° and 80°, as well as a laboratory chamber, a refrigerator chamber, a cold chamber, a climate chamber or an environmental simulation chamber with at least one such Peltier module.

An apparatus for cooling bottled beverages may include an open-topped vessel defining a bottle chamber. The vessel may have a tubular wall and a base. The apparatus may further include a cooling device in thermal communication with the base of the vessel and with a heat exchanger. The apparatus may also include a tubular housing surrounding the vessel and enclosing the cooling device and the heat exchanger. Additionally, the apparatus may include a fan configured to provide an air flow along an airflow path. The airflow path may extend from an inlet of the housing, across the heat exchanger, to an outlet of the housing.

In one aspect, a portable liquid pump with integrated chiller and heater system includes a pump component includes a pump, a liquid chamber, an inlet port and an outlet port. The pump component seals a liquid so that it does not escape except by the inlet port and the exit port. The pump component pressurizes and directs the liquid in a warm state from the inlet port over a Thermo-electric element-based cold-side heat exchanger and through the outlet port. A Thermo-electric element component includes the Thermo-electric element-based cold-side heat exchanger and a hot-side heat exchanger, wherein the Thermo-electric element component converts an electrical current into a temperature difference that in turn causes heat to flow from the Thermo-electric element-based cold-side heat exchanger to the hot-side heat exchanger. A battery component includes an electrical energy storage component that provides electrical power to the Thermo-electric element component that in turn pumps heat from the Thermo-electric element-based cold-side heat exchanger to the hot-side heat exchanger.

A thermal block assembly for use in a biological analysis system includes a sample block, a heating and cooling element, a heat sink including a surface, the surface including a plurality of projections for engaging the heating and cooling element to hold the heating and cooling element on the heat sink. A thermal block assembly for use in a biological analysis system includes a heating and cooling element, a sample block including a lower surface configured to be thermally coupled to the heating and cooling element, one or more temperature sensors configured to extend through the one or more slots of the lower surface of the sample block, and one or more thermal pads between the one or more temperature sensors and heating and cooling element.

A flatpack air chiller device is disclosed. In embodiments, the air chiller device includes a primary chiller or pre-chiller subsystem and a secondary or main chiller subsystem within a housing. The pre-chiller subsystem receives and chills ambient air via cold-side contact with a primary thermoelectric device and directs the pre-chilled ambient airstream to the hot side of a secondary thermoelectric device. The secondary or main chiller subsystem is connected to a recirculating air stream, e.g., circulating through the interior airspaces, compartments, or bays of a galley structure. The pre-chilled ambient airstream absorbs heat from the secondary hot side to progressively chill the recirculating air stream, which is in contact with the cold side of the secondary thermoelectric device before recirculation back into the galley structure interior.

A modular lunch box 100 is disclosed, comprising a base 102 to receive containers 104 to store food articles and having one or both of heating and cooling devices; and a top lid 106 removably received on base to cover and individually seal the containers. A control module 110 is detachably received through a first aperture 112 in top lid 106 such that control module 110 rests against a step portion of containers 104 for operative coupling with heating and cooling devices to control their temperature. Without control module 110, lunch box 100 is usable as a conventional lunch box. Control module 110 includes a wireless communication module to receive user inputs to configure the lunch box for heating and/or cooling of food article at desired times, to desired temperatures. A battery pack positioned over top lid 106, gets coupled to control module 110 to meet power requirement.

An entrance refrigerator includes an upper first cold air supply on an upper portion and a lower second cold air supply on a lower portion, and an external air guide provided between the upper first cold air supply and the lower second cold air supply.
