Waste heat recapture from cooking appliance

Abstract

A waste heat extraction and capture device located in a stream of waste heat from a cooking appliance extracts heat energy from heated air destined for venting to an ambient exterior. A heat transfer element disposed in a vent hood above the cooking surface recovers heat for recapturing thermal energy that would otherwise be simply expelled. A fluid traveling through the heat transfer element is heated by the passing exhaust stream of waste heat, and can be stored for subsequent use, such as for potable hot water, interior space heating, or other cooking processes. An attachment strap, bracket or mechanism secures the heat transfer element in the vent hood that is typically tapered for effective heat gathering, and is positioned downstream of filters or traps for grease so as to avoid clogging the heat transfer element.
