An electronic ingestible gas cooling device that reduces the temperature of a gas (e.g smoke, vapors) before being ingested while simultaneously solving or minimizing problems such as user discomfort from too much heat, preparation inconvenience, changing gas temperature over time and/or changing the flavor or potency experience.

The device cools by improving the transfer of heat away from the hot gas using a combination of an electrically powered thermoelectric cooling device(8), water, heat distribution device(2), fan(10) and an elongated cooling path(4,5) designed to increase the time and the amount of surface area contact between the gas and the cool surface.

A vacuum insulator including a heat diffusion block placed in a vacuum space; a thermoelectric module, in the vacuum space, coming into contact with the heat diffusion block so as to exchange heat therewith: and a heat sink exchanging heat with the thermoelectric module and placed in a first space or a second place. High heat-insulation performance and heat-transfer performance can be obtained.

The invention relates to An aircraft on-board kitchen module (1) comprising at least one heater and/or cooler with at least one first compartment (2) for drinks and/or food and whose temperature can be conditioned by at least one thermoelectric element (5) having a first and a second heat exchanger (8, 9), one of the heat exchangers (8, 9) forming a cold side and the other heat exchanger (8, 9) forming a hot side of the thermoelectric element (5) such that heat generated by the thermoelectric element (5) is dissipated by a primary coolant from a central cooling system (11) of the aircraft, the primary coolant being supplied via a coolant duct (10) that is selectively supplied with ambient air from the cabin and/or conditioned cold air from the central cooling system (11) of the aircraft.

A vehicle seat system is provided that includes heating, cooling, and occupant sensing functionality in a single unit. The system includes carbon nanotube (CNT) elements disposed adjacent the seat surface. The CNT elements may be woven or stitched to a vehicle seat cover, or may be disposed in a mat that is placed between a seat cushion and the seat cover. The CNT elements may be used for heating, cooling, and occupant sensing, without requiring separate units or circuits. The system may include Peltier elements attached to the CNT elements, with the Peltier elements transferring heat between the CNT elements and a heat bank. The heat bank may be in the form of a heat sink, or the heat bank may be the seat rails of the vehicle seat, with the Peltier elements attached to the seat rails.

A device including a bottom electrode on a substrate and a top electrode on a substrate separated by a fixed distance from each other. Semi-insulator layers with proper electrical conductivity are attached to the bottom and top electrodes. Disposed between the substrates is a flexible S-shaped polymer stack having electrode layers with one end of the stack attached to the top substrate and the other end in contact with the bottom substrate. When a voltage is applied between the stack and the electrode layer on the bottom substrate, the stack is induced by electrostatic force to deflect in a rolling wave-like motion. While the voltage applied between the stack and bottom electrode is turned off, the static charges on the semi-insulator layer can move away quickly due to the proper electrical conductivity of the semi-insulator layer.

Devices, systems, and methods are provided for heating and cooling substances, such as food and beverages. A portable device may have an exterior surface and an interior surface, with one or more heating elements positioned at least partially between the exterior surface and the interior surface, and with one or more cooling elements positioned at least partially between the exterior surface and the interior surface. The portable device may include one or more power sources operatively connected to the one or more heating elements and the one or more cooling element, and may include at least one processor that controls, based on the one or more power sources, activation of one of the one or more heating elements or the one or more cooling elements at a time.
