The piezoelectric cooling system includes a first piezoelectric cooling element and a second piezoelectric cooling element. The first piezoelectric cooling element is configured to direct a fluid toward a surface of a heat-generating structure. The second piezoelectric cooling element is configured to direct the fluid to an outlet area after heat has been transferred to the fluid by the heat-generating structure.

The present invention relates to a clothes-handing apparatus comprising: a cabinet having a holder opening provided at an upper panel; an air moving part provided inside the cabinet so as to generate an air flow; a holder which is withdrawable from the cabinet through the holder opening and on which clothes are hung; and holder air holes provided at the holder so as to supply air to the clothes hung on the holder.

Cooling sub-assemblies with thermoelectric element(s), coupling clamps, hot side and cold side heat exchanger having a direct insertion or removal of cooling modules onto a fixed mounting frame arranged in rows and columns to produce desired and required cooling levels.

The present disclosure is related to thermoelectric panels and their use in cooling and heating systems. The cooling/heating systems may include a plurality of thermoelectric panels. The panels may include thermoelectric devices embedded between a housing formed by heat conductive layers and edge structures for preserve a low thermal conductivity volume.

A cooling system and method for using the cooling system are described. The cooling system includes a plurality of individual piezoelectric cooling elements spatially arranged in an array extending in at least two dimensions, a communications interface and driving circuitry. The communications interface is associated with the individual piezoelectric cooling elements such that selected individual piezoelectric cooling elements within the array can be activated based at least in part on heat energy generated in the vicinity of the selected individual piezoelectric cooling elements. The driving circuitry is associated with the individual piezoelectric cooling elements and is configured to drive the selected individual piezoelectric cooling elements.

A heat pump that includes a thermoelectric device(s) and a heat sink having a raised portion with a top surface for thermally coupling with a planar face of the thermoelectric device(s). The raised portion of the heat sink includes an outer periphery and a raised central region surrounded by a void region to provide more uniform thermal conductivity when clamped within an assembly. The raised central region is shaped in an any shape corresponding to a shape of uneven thermal conductivity due to clamping pressure applied to the heat sink. The void region can be substantially contiguous and entirely circumscribe the central raised region. The device can optionally include discrete supports formed of a less thermally-conductive material within the void region. The supports can be elastomeric, such as O-rings, and disposed within pockets defined within the void region.

An environmental control unit for use with a transport container is disclosed. The environmental control unit includes a thermoelectric device, a fan configured to blow air across the thermoelectric device, a cooling module, a controller in electronic communication with the thermoelectric device and the fan, and a communication module in electronic communication with the controller. The communication module is configured to transmit parameters of the environmental control unit to a computing device through wireless communication. The controller is also configured to determine a present location of the transport container, determine a destination of the transport container, evaluate an internal temperature of the transport container, and control an on or off condition of the thermoelectric device based on the present location, the destination, and the internal temperature of the transport container.

A container has a chamber and a phase change material (PCM) that can remove heat from the chamber. The container can have a thermal conductor movably coupled in the container between a retracted position and a deployed position, where in the deployed position, while on a heat sink unit, the thermal conductor can draw heat from the PCM to solidify or charge the PCM, which can then maintain the chamber in a chilled state for a prolonged period of time. The container can have one or more heating elements in thermal communication with the chamber and operable to add heat to the chamber to increase or maintain a temperature of the chamber in a heated state for a prolonged period of time.

A sensor system for detecting at least one analyte in an environment includes a dehumidifier system including at least one of a condenser unit and a desiccant unit and a sensor responsive to the analyte in fluid connection with the dehumidifier system.

Disclosed is a personal small refrigerator using a Peltier. The small refrigerator includes a body having storage space formed therein, a front door a door. And the small refrigerator includes a division shelf having a plurality of air ventilation holes for dividing the storage space into upper storage space and lower storage space for passing cold air therethrough. 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.
