Abstract: An electric heater for thermal energy storage comprises a core comprising a phase change material. A plurality of electric heater elements are positioned within the core for heating the core to charge the core with stored thermal energy. A housing surrounds the core and has an air input opening connected to an output end of an air input conduit and an air output opening connected to an input end of an air output conduit. A first air path extends through the core between the air input opening and the air output opening. An inlet end of the air input conduit is connected to an air supply conduit, for connection to a supply of an external air flow, at a first junction; an outlet end of the air output conduit is connected to a heated air outlet conduit, for outputting heated air from the electric heater, at a second junction; and a bypass conduit connects the first and second junctions and defines a second air path external of the core. A temperature sensor senses the temperature of heated air in the heated air outlet conduit, or downstream of the heated air outlet conduit in the direction of air flow through the heated air outlet conduit. An air flow control valve mechanism in at least one of the bypass conduit and the air input conduit variably controls a flow rate of air flow along the bypass conduit and/or the air input conduit based on the temperature of the heated air measured by the temperature sensor, thereby variably to control the ratio of the volume flow rate of air along the first and second air paths.

Abstract: Ein Energiespeicher zum Speichern von elektrischer Energie in Form von Wärmeenergie umfasst einen elektrischen Heizer (10) zum Umwandeln von elektrischer Energie in Wärmeenergie. Es sind mehrere aufrecht angeordnete Vertikalstangen (21) vorhanden, die an ihren unteren Enden gehalten sind, so dass eine thermische Expansion nach oben frei ermöglicht ist. An jeder Vertikalstange (21) sind mehrere Horizontalstangen (22) befestigt, welche sich in horizontaler Richtung erstrecken und dem Speichern von Wärmeenergie dienen. Die horizontalen Enden jeder Horizontalstange (22) sind frei, so dass eine thermische Expansion in horizontaler Richtung frei ermöglicht ist.

Abstract: The present invention discloses an ultra-high voltage electro-thermal energy storage device, comprising a separated heat energy storage body part, a heat exchanger part and an outer thermal insulation layer part. The separated heat energy storage body is composed of an isolation layer, a safety gap, a heat storage module, an electric heating wire, a convection chamber for heat dissipation, an insulating air-duct, a power supply sheath, a back flow air passage, a motor, a front end of a leading wire for a power supply, a tail end of the leading wire for the power supply, and an outer thermal insulation layer. The separated heat energy storage body is a component of the ultra-high voltage electro-thermal energy storage device, and 3(n+1) separated heat energy storage bodies are provided for composing the ultra-high voltage electro-thermal energy storage device with any two adjacent separated heat energy storage bodies being isolated by isolation layers and the electric heating wires of the n separated heat energy storage bodies being connected end to end to be in series. The heat energy storage bodies supply electric power through three phases, and in each phase, n separated heat energy storage bodies are connected in series, so as to address the issue of terminal voltages on terminals of the separated heat energy storage bodies being too high. The present invention can be configured conveniently, and is suitable for various voltage levels above 10 KV, and can be used as a heat storage device having an operating voltage of more than 500 KV.
