476 results about "Thermal Battery" patented technology

A thermal energy battery is a physical structure used for the purpose of storing and releasing thermal energy—see also thermal energy storage. Such a thermal battery (a.k.a. TBat) allows energy available at one time to be temporarily stored and then released at another time. The basic principles involved in a thermal battery occur at the atomic level of matter, with energy being added to or taken from either a solid mass or a liquid volume which causes the substance's temperature to change. Some thermal batteries also involve causing a substance to transition thermally through a phase transition which causes even more energy to be stored and released due to the delta enthalpy of fusion or delta enthalpy of vaporization.

Thermal Battery Systems Comprising Emitter Units Equipped with Vapor Barriers

Described herein are thermal battery systems comprising emitter units equipped with vapor barriers. A vapor barrier prevents vapors (e.g., released by the emitter base during its heating) from reaching a TPV receiver when the TPV receiver is inserted inside the emitter unit. For example, the emitter base may comprise graphite, while the vapor barrier may comprise tungsten (at least on the TPV-facing surface). At the emitter unit's operating temperature of about 2000° C., the vapor pressure of tungsten is about 10,000 times lower than that of graphite (e.g., 10−7 Pa vs. 10−3 Pa). As such, the graphite emitter base may release appreciable amounts of vapors, which (if not blocked) can deposit on the TPV receiver (operating at less than 100° C. even when inside the emitter unit cavity). The vapor barrier blocks this vapor from reaching the cavity, while the emitter base provides mechanical support to the vapor barrier.
