Problems solved by technology

Some devices attempt to use this waste heat (e.g., waste heat generated by a vehicle's engine can be directed to the interior of the vehicle to provide heat during the winter months) but such systems are generally inefficient and do not address issues such as heating by burning fossil fuels (e.g., gasoline, coal). , oil, etc.) to provide the initial requirements for work

[0018] Process overview

[0019] An embodiment of ETD utilizes a process that includes (at least) two spatially separated surfaces that are chemically active with respect to a gas that is subjected to a general dissociation reaction Figure 1A An embodiment of this process using two parallel surfaces 120 and 140 is illustrated. The two (or more) surfaces 120 and 140 exhibit mos...

Abstract

An Epicatalytic Thermal Diode (ETD) includes one or more ETD cells. Each cell comprises first and second surfaces with a cavity between them, which contains a gas that is epicatalytically active with respect to the pair of surfaces. The surfaces chemically interact with the gas such that the gas dissociates at a faster rate proximate to the first surface than it does proximate to the second surface. Thus, a steady-state temperature differential between the first surface and the second surface is created and maintained. In various applications, multiple ETD cells are connected in series and / or parallel.

Description

[0001] Cross references to related applications [0002] This application claims the benefit of the U.S. Provisional Patent Application No. 61 / 828,419 filed on May 29, 2013, entitled "Epicatalytic Thermal Diode"; the U.S. Provisional Patent entitled "Epicatalytic Thermal Diode" filed on May 29, 2013 Application No. 61 / 828,421; and US Patent Application No. 14 / 289,322 entitled "Epicatalytic Thermal Diode" filed on May 28, 2014, all of which are incorporated herein by reference in their entirety. Technical field [0003] The topics described in this article generally relate to managing heat flow, and more particularly to a device that generates and maintains a steady-state temperature difference. Background technique [0004] Heat usually flows from hot to cold, and the temperature gradient is relaxed so that the isolated system finally reaches a thermodynamic equilibrium characterized by a single uniform temperature. Currently, work must be done in order for the equipment to generat...
