The cavity is partitioned into an upper chamber and a lower chamber by a diaphragm. The lower chamber is in communication with an outer space.

Disclosed is an energy-saving and environment-friendly double-row air duct heater, including a bottom plate and a shell. A motor and fan blades are arranged on one end in the shell. The upper part of the shell is provided with a control device. A heating component is arranged on the other end in the shell. An air inlet is formed at the rear end of the shell, and an air outlet is formed at the front end of the shell. The heating component includes an air volume drainage device. Two groups of electric heating pipes are arranged on both sides of the air volume drainage device. Each group of electric heating pipes is composed of a plurality of vertically arranged electric heating pipes. An air guiding passage is formed between two adjacent electric heating pipes.

A fluid conditioning system having a housing within a fluid inlet and a fluid outlet. A rotating shaft extends within the housing and secures a conductive component exhibiting fluid flow redirecting vanes for communicating an inlet fluid flow with an outlet fluid flow. Magnets or electromagnets are arranged in a stationary array within the housing in proximity to the rotary conductive component and, upon rotating the conductive component relative to the magnetic plates, thermal conditioning of the fluid flow is generated from creation of high frequency oscillating magnetic fields and which is conducted through the rotating component for outputting through the outlet of the housing. Peltier or other thermoelectric generator elements can be incorporated into the housing. The conductive components or plates can include any of a number multi-metal/multi-alloy plate configurations.

A heating unit for heating fluid is described having at least one electrical resistance heating element on an outer surface of a tube. At least one indexed groove is provided around a surface of the tube allowing for at least one retention clip to hold the electrical resistance heating element. A heating chamber is also provided to enclose a portion of the tube and to provide a flow channel therebetween. The heating chamber includes an optical sensor to detect overheating of the at least one electrical resistance heating element. Fluid is heated by flowing over the surface of the at least one electrical resistance heating element and through the tube.

The heater device has a sheet shaped main body having a heat generating portion heated by energization and a radiating surface for radiating radiant heat toward a heating object by using heat in the heat generating portion, a plate shaped member arranged on an opposite side with respect to the radiating surface of the main body, and an air layer forming member for forming an air layer between the main body and the plate shaped member arranged on a side opposite to the radiating surface of the main body.

A thermal energy storage (TES) component includes a shell having first and second ports, and at least a first set of thermally conductive sealed containers that contain a TES media for storing thermal energy. A first set of sealed tubes containing a first TES media are in a first section of the shell, and a second set of sealed tubes containing a different TES media are in a second section of the shell. Electric heating elements are immersed in at least some of the tubes, and may extend only from one end of the tube. In some embodiments more than one heating element is immersed in the TES media and positioned to enhance convective flow. In some embodiments electric heating elements are disposed externally on the sealed tubes. Some tubes are tapered or frustoconical, with heating elements provided in a larger-diameter portion of the tubes.

A household appliance includes a channel section which can be heated from outside and can be configured for passage of a fluid, and a plurality of electrically interconnected heating conductor elements for heating purposes, with at least some of the heating conductor elements being electrically connected together in parallel and including a component arranged in a flow direction of the fluid.
