A system for cooling a mobile phone and method for using the system are described. The system includes an active piezoelectric cooling system, a controller and an interface. The active piezoelectric cooling system is configured to be disposed in a rear portion of the mobile phone distal from a front screen of the mobile phone. The controller is configured to activate the active piezoelectric cooling system in response to heat generated by heat-generating structures of the mobile phone. The interface is configured to receive power from a mobile phone power source when the active piezoelectric cooling system is activated.

A fast-rate thermoelectric device control system includes a fast-rate thermoelectric device, a sensor, and a controller. The fast-rate thermoelectric device includes a thermoelectric actuator array disposed on a wafer, and the thermoelectric actuator array includes a thin-film thermoelectric (TFTE) actuator that generates a heating and/or a cooling effect in response to an electrical current. The sensor is configured to measure a temperature associated with the heating or cooling effect and output a feedback signal indicative of the measured temperature. The controller is in communication with the fast-rate thermoelectric device and the sensor, and is configured to control the electrical current based on the feedback signal.

A refrigerator include: an inner case having a storage chamber; a thermoelectric module including a thermoelectric element and a cooling sink; a fan configured to circulate air, to the storage chamber; a fan cover configured to cover the fan and having an upper discharge hole, a lower discharge hole, and an inner suction hole formed between the upper discharge hole and the lower discharge hole; a first receiving member disposed in the storage chamber; and a second receiving member disposed over the first receiving member to be spaced apart from the first receiving member. At least a portion of each of the inner suction hole and the lower discharge hole faces a portion between the first receiving member and the second receiving member, and at least a portion of the upper discharge hole faces a portion between a top surface of the storage chamber and the second receiving member.

A portable cooler container is provided. The temperature control system cools a chamber of the container to transport temperature sensitive contents via the container. An electronic display screen on one of the lid and the container body selectively displays an electronic shipping label for the portable cooler container.

A heat exchanger module (HEM) and system uses a flexible substrate with one or more open channels, to which a substrate cover is bonded, thereby forming closed channels in the flexible substrate. Thermoelectric coolers (TECs) are attached to optional thermally diffusing copper squares atop the substrate cover. An interface cover is attached to the TEC tops, with a compliant thermally conductive material opposite the TECs and ultimately in contact with a patient. A liquid is passed through the closed channels, which act as thermal references for the TECs. Current is supplied by a controller to the TECs to induce TEC cooling or heating relative to the liquid. One or more temperature sensors detect the temperature of the interface cover, which are used as inputs to the control of the TEC supply current. The HEM may be used for heating, cooling, or cycling between heating and cooling for various medical uses.

A heat exchange module alone or part of a system including a control console. The module includes a channel assembly and a heat exchange stack attached thereto, and can be used to directly cool and/or heat tissue or skin. The channel assembly includes a liquid channel. The stack can include a pair of spaced plates with thermoelectric coolers exchangers, heat reflective layers, and a core composite layer which keeps the plates spaced. To provide flexibility of the module to better fit on round body parts the stack can include a thermally-conductive plate construction between the plates which has rotational flexibility axes in the X and/or Y directions between plate portions. Optionally the channel can include windows to which the plate portions are sealed. The heat exchange stack separately or together with the channel assembly can be secured in the thickness direction with mechanical securements such as sewing or tacking to also provide for greater flexibility.

A water cooling apparatus and a water purifier having a water cooling apparatus is provided. The water cooling apparatus may include a case, a water tank provided within the case, a cooling block provided to be in contact with the water tank and to cool the water tank through heat exchange, a thermoelectric element having one side in contact with the cooling block and provided so as to transfer heat from the one side to another side of the thermoelectric element when power is applied thereto, an insulator provided within the case and that covers the water tank and the cooling block, and a heat dissipation block provided outside of the case and provided to be in contact with the other side of the thermoelectric element to dissipate heat from the other side of the thermoelectric element.

In an entrance refrigerator, when a living organism such as a companion animal is detected in a storage compartment, a drain port provided at the bottom of the storage compartment is opened, such that air outside the storage compartment flows into the storage compartment through the drain port.

A mobile refreshment cart includes an open refreshment chamber exposed to an environment surrounding the refreshment cart and configured to receive refreshment containers therein. The mobile refreshment cart also includes a thermally conductive plate having a first surface facing the open refreshment chamber, and having a second surface opposite to the first surface. The mobile refreshment cart also includes a thermoelectric cooler coupled to, and directly contacting, the second surface of the thermally conductive plate. The thermoelectric cooler is configured to extract heat from the thermally conductive plate through the second surface of the thermally conductive plate. The refreshment cart also includes a fan configured to urge an air flow over a portion of the thermoelectric cooler and to the environment, such that the air flow extracts the heat from the thermoelectric cooler and expels the heat to the environment.

The invention is directed to an energy efficient thermoelectric heat pump assembly. The thermoelectric heat pump assembly preferably includes two to nine thermoelectric unit layers capable of active use of the Peltier effect; and at least one capacitance spacer block suitable for storing heat and providing a delayed thermal reaction time of the assembly.
