A refrigerator that has a fresh food compartment, a freezer compartment, and a door that provides access to the fresh food compartment is disclosed. An icemaker is mounted remotely from the freezer compartment. The icemaker includes an ice mold with an icemaking cycle having a liquid to ice phase change. A thermoelectric device has a cold side and a warm side. A controller is in operable communication with an input to the thermoelectric device. A sensor is in operable communication with the input to the thermoelectric device and the controller. A feedback response from the input to the thermoelectric device monitors the liquid to ice phase change of the icemaking cycle.

A method for managing a temperature of a device includes determining a temperature of a circuit or a package including the circuit, and selectively operating a thermoelectric semiconductor based on the determined temperature to adjust the temperature of the circuit or the package.

A device includes a first board having a first area and a second area not overlapping the first area; and a thermoelectric semiconductor disposed between the first board and the second board at the first area of the first board configured to supply a voltage to the thermoelectric semiconductor; a package disposed at the second area of the first board.

An apparatus for waste heat recovery is provided. The apparatus includes a base block disposed adjacent to a heat source, a thermoelectric generator including a first end and a second end, the first end being thermally coupled to the base block and configured to receive heat from the heat source, and a thermoelectric cooler including a third end and a fourth end, the third end being thermally coupled to the second end. The thermoelectric cooler is configured to receive an electric current, which causes the third end to cool and the fourth end to heat such that the third end conducts heat from the second end. Related apparatus, systems, techniques, and articles are also described.

A balance (30) is a single unit with a weighing pan (21) enclosed in a weighing compartment (22). A housing (23) adjoins the weighing compartment. The balance housing contains a weighing cell compartment (24) enclosing a weighing cell, an electronics compartment (25) containing electrical and electronic circuit elements, a thermoelectric heat pump module (27) and a heat flow controller (28). The balance is equipped to determine a net heat flow (P.sub.net) inside the housing in the direction from the weighing cell compartment to the electronics compartment. The heat flow controller uses the net heat flow as a control input to regulate the the thermoelectric heat pump module, arranged inside the housing. The control input is used to generate an active heat flow (P.sub.A) with magnitude and direction for holding the net heat flow at a level equal to the rate of heat dissipation produced inside the weighing cell compartment.

Provided is a compact lightweight transport box in which the internal temperature distribution is minimized and accurate temperature regulation can be performed. The transport box includes an insulating container, an internal heat conducting container mounted in the insulating container, and an insulating cover body with a cover internal side heat conducting plate exposed on an inner surface facing the opening part of the internal heat conducting container, in which, with the opening part of the insulating container closed by the insulating cover body, the cover internal side heat conducting plate is near an opening end of the internal heat conducting container.

Proposed is a thermoelement heat exchange module including a body and a thermoelement. The body has a cooling water flow path through which cooling water flows and has an opening which communicates with the cooling water flow path, and has an inlet which is formed at a first side thereof to communicate with the cooling water flow path and through which cooling water is introduced and has an outlet which is formed at a second side thereof to communicate with the cooling water flow path and through which cooling water is discharged. The thermoelement has a first surface thereof coupled to a portion where the opening of the body is formed such that the first surface is exposed on the cooling water flow path. The cooling water flow path has a portion having a relatively small hydraulic diameter in a flow direction of cooling water.
