A system includes a flight vehicle and one or more deployable radiators. Each deployable radiator includes a structure configured to receive thermal energy and to reject the thermal energy into an external environment. The structure includes (i) multiple inline and interconnected thermomechanical regions and (ii) one or more thermal energy transfer devices embedded in at least some of the thermomechanical regions. The one or more thermal energy transfer devices are configured to transfer the thermal energy between different ones of the thermomechanical regions. At least one of the thermomechanical regions includes one or more shape-memory materials configured to cause a shape of the structure to change. The thermomechanical regions may include one or more heat input regions configured to receive the thermal energy, one or more heat rejection regions configured to reject the thermal energy into the external environment, and one or more morphable regions including the one or more shape-memory materials and configured to change shape.

Embodiments disclosed herein relate to devices, systems, and methods for cooling and/or heating a medium as well as cooling and/or heating an environment containing the medium. More specifically, at least one embodiment includes a heat pump that may heat and/or cool a medium and, in some instances, may transfer heat from one location to another location.

The various technologies presented herein relate to fabrication and operation of a heat exchanger that is configured to extract heat from an underlying substrate. Heat can be extracted by way of an air gap formed between an impeller and a baseplate. By utilizing a pump to create an initial air gap that is further maintained by rotation of the impeller relative to the baseplate, a spring can be utilized that can apply a force of greater magnitude to the impeller than is used in a conventional approach, thus enabling the weight of the impeller to be negligible with respect to a width of the air gap, thereby conferring the desirable feature of orientation independence with respect to gravity with no performance degradation.

A refrigerator, including a sealed refrigeration system, is provided herein. The sealed refrigeration system may include a compressor, a phase separator, and a rotatable heat exchanger. The compressor may compress a refrigerant fluid through the sealed refrigeration system. The phase separator may be in fluid communication with the compressor. The phase separator may include a separator body defining an inner face and an outer face. The inner face may define a refrigerant cavity within the phase separator body. The outer face may be directed away from the refrigerant cavity opposite the inner face. The rotatable heat exchanger may include a thermally conductive body defining a dynamic shear surface directed toward the outer face of the separator body. Moreover, a set fluid gap may be defined between the dynamic shear surface and the outer face.

A rocker chiller includes a chilling tank and a baffle assembly. The baffle assembly includes a drive shaft, a baffle blade extending along a bottom of the tank and a plurality of spaced-apart and elongate baffle members extending in a radial direction from the drive shaft towards the bottom of the tank. The elongate baffle members contact the drive shaft at spaced-apart locations along the drive shaft and define a plurality of openings therebetween. The elongate baffle members are sized and shaped to push at least a majority of the carcasses laterally through the heat exchanging liquid in a direction generally orthogonal to a lengthwise forward movement of the carcasses from the first end of the tank to the second end of the tank.

An electronic apparatus with a heat-dissipation system includes a heat-dissipation device including a base, a heat-dissipation structure rotatably disposed on the bottom base, and a drive mechanism configured to selectively rotate the heat-dissipation structure toward one of a plurality of predetermined orientations.

A cooling apparatus is disclosed. The cooling apparatus comprises a housing, a first liquid and a second liquid located within the housing. The first liquid has a higher density and lower boiling point than the second liquid. The cooling apparatus further comprises a heat exchanging apparatus to transfer heat to the first liquid to evaporate the first liquid to form a first liquid vapour. The cooling apparatus also comprises a plurality of independent energy dissipating members that extend through the housing. These members move in response to a fluid flow created by the interaction of the first liquid vapour and the second liquid and transfer heat to a volume external to the housing. The cooling apparatus can cool a body whilst drawing minimal or even no electrical power. As such the cooling apparatus is environmentally friendly and cheaper to operate.

The present disclosure relates to a cooling device for heat treatment that performs heat treatment by cooling individually or as a whole a heated metal object. The cooling device for heat treatment includes: a chamber to which a plurality of objects is charged through one open side thereof; an individual cooling unit configured to be provided in the chamber, to individually cover the object, and to spray a cooling medium onto the object; and a driving unit configured to be provided on the chamber and to move the individual cooling unit in an up and down direction. With this configuration, it is possible to obtain a required cooling capacity by cooling individually or as a whole a heated metal object.
