The invention relates to an electric heater, in particular auxiliary heating system, for a motor vehicle, comprising a volume (15) for receiving and conducting a liquid, in particular water, as well as a liquid inlet (13) and a liquid outlet (14) in such a manner that liquid can flow into the volume (15) via the liquid inlet (13) and can flow out via the liquid outlet (14), wherein at least one heating element (16), in particular a heating resistor, and a flow-conducting device (12) is disposed in the volume (15), wherein the flow-conducting device (12) comprises at least one flow-deflecting and/or turbulence-generating device (25) for deflecting the flow and/or for generating turbulence.

Provided is an apparatus for manufacturing beverage. The apparatus includes a heat exchanger to heat a fluid. The heat exchanger includes a body including a first end portion and a second end portion, and the second end portion is opposite to the first end portion. The apparatus further includes a heater embedded in the body, a first pipe installed in the body and guiding the fluid in a first direction from the first end portion of the body to the second end portion of the body, and a second pipe installed in the body and guiding the fluid output from the first pipe in a second direction opposite to the first direction.

A fluid heater includes: a passage member having a passage formed therein; a heater for heating the passage member; a fixing member for fixing the passage member to a fluid control device; and a connection member connected to the passage member so as to allow fluid to flow into the passage member. The passage has a helical shape.

An electrical heating apparatus for a motor vehicle includes a volume for receiving and conducting a liquid, a liquid inlet and a liquid outlet. The liquid can flow in through the liquid inlet into the volume and can flow out through the liquid outlet. At least one heating element is arranged in the volume. At least one deviating device is provided in such a way that the liquid flowing from the liquid inlet to the liquid outlet is deviated so that a flow path is increased.

A fluid-heating device for heating fluid with a heater includes: a heating portion that is molded so as to cover the surrounding of the heater; and a support body integrally cast into the heating portion, the heating portion being molded in a state in which the heater is supported by the support body in a die for molding the heating portion.

The invention provides a heating device comprising a base structure comprising a fluid channel and a heating element, the heating element arranged in use to heat fluid within the fluid channel, the heating device further comprising a cooling means, arranged in use to cool the fluid channel.

A system for overheating gases at the inlet of a SOEC/SOFC-type solid oxide stack, the stack including a main body that has first and second zones separated by a median plane, and inflow and outflow conduits, the zones include gas circulation circuits extending in the form of a spiral and communicating by means of a passage passing through the main body. A gas flow to be heated entering the inflow conduit circulates in the first gas circulation circuit and passes through the passage to then circulate in the second gas circulation circuit and in the conduit for the outflow of the reheated gases in order to reach the inlet of the SOEC/SOFC-type solid oxide stack.

The invention relates to a heating system component for a heating system for heating a fluid medium, with a carrier unit, and a heating unit coupled to said carrier unit, wherein said carrier unit comprises a wet side and a dry side, wherein said wet side corresponds to a surface of said carrier unit configured to be in contact with said fluid medium, wherein said dry side is located on a surface opposite to said wet side; and wherein said heating unit is recessed in a groove provided on said dry side of the carrier unit. A temperature sensor, in particular an NTC thermistor, positioned to measure a temperature of a fluid medium at the wet side of the carrier unit, wherein the temperature sensor is effectively thermally insulated from the heating unit.

Example embodiments relate to a device for heating a medium and air. A heating source generates thermal energy by the combustion of a fuel-air-mixture. A heat exchanger serves to heat air passed along an exterior side, has an interior space into which flue gas generated during combustion of the fuel-air-mixture flows, has a fin structure on the exterior side, and transmits thermal energy to the medium pipe. The electric heating element generates thermal energy, the heat exchanger having integral structures for accommodating the electric heating element and the medium pipe. The medium pipe and the electric heating element are guided around the interior space of the heat exchanger.

An inline heater includes a heater core that includes a heat spreader assembly comprising a tubular heat spreader that extends axially along a longitudinal axis and that comprises an external surface. The heat spreader assembly includes a fluid inlet and a fluid outlet. At least one conduit extends helically about the longitudinal axis of the heat spreader between the fluid inlet and the fluid outlet to define a fluid heating flow path that fluidically connects the fluid inlet and the fluid outlet. The heat spreader assembly further comprising an electrically operated heating element for heating the heat spreader.
