Abstract: The present invention relates to a cartridge-type inline heater including: a heat exchanging unit including a body part in which a mounting part is formed in a longitudinal direction, and swirl parts coiled in a spiral along the longitudinal direction of the body part, and configured to induce a flowing-in working fluid to flow along the swirl parts; and a heater inserted in a longitudinal direction of the heat exchanging part to heat the working fluid which is in contact with the heat exchanging unit. Accordingly, the cartridge-type inline heater capable of heating the working fluid so as to have improved durability and uniform temperature distribution is provided.

Abstract: A water heater comprises an inner container (1) and an outer container (2). An upper part of the inner container (1) is connected with an insulating water inlet pipe (3) which communicates with a cavity of the inner container (1); the outer container (2) is provided to encase the inner container (1) and it is axially movable relative to the inner container (1); two different heating electrodes (4) are connected with one end of the inner container (1) and one end of the outer container (2) respectively; water outlet holes (5) are provided on the inner container (1) and the outer container (2). As a result, the insulating water inlet pipe forms a hot water supply circuit in a sandwiched layer between the inner and the outer containers. By adjusting the spaces between the inner and the outer containers to regulate electrical current, water temperature control is achieved.

Abstract: An electrical liquid heating system and method of heating a liquid includes providing at least two spaced apart electrical conductors and applying an electrical energy source to the conductors. A liquid is directed into contact with the conductors thereby delivering electrical energy to the liquid. Electrical energy is delivered to the liquid at a power level that is sufficient to generate an electrical current to produce resistive heating of the liquid. The electrical energy may be delivered to the liquid at a power level that is sufficient to break at least some molecular bonds of molecules defining the liquid. A regulator may be provided for regulating delivery of electrical energy to the liquid.

Abstract: An in-line water heater utilizing electrically conductive polymer structures for electrodes. The area of electrodes that confront one another can be varied, and thereby the temperature to which the water is heated can be variably adjusted. The heat is not generated by the electrodes, but instead by the resistance of the water to the electrical current flowing between them. While the electrodes can be moved relative to one another, preferably they will be fixed, and an non-electrically conductive current gating plate can adjustably be placed between them to variably adjust the amount of confronting areas. A field obstructor can be provided at the inlet and outlet of the heater housing to prevent the exit of electrical current from the heater electrodes, and also non-conductive grounding screens in place for secondary safety.

Abstract: A heater comprises a casing, which has an interior chamber. It further comprises a rotor, which is formed as an impeller on the one hand and as an eddy-current disk on the other, and a magnet support, which is equipped with permanent magnets and disposed non-rotarily in the casing and which is displaceable into an operating position in the direct neighborhood of the eddy-current disk and into a position of rest spaced therefrom. The eddy-current disk and the magnet support equipped with permanent magnets are rinsed by water.

Abstract: Electroheating apparatus and methods utilize a dielectric structure defining a conduit course of relatively small cross-sectional area and electrode surfaces of relatively large area so that the electrical current density in a region of the conduit remote from the electrodes is substantially higher than the current density at the electrode surfaces themselves. The system uses relatively high electrical resistance and relatively high voltages to provide substantial heating effect with low total currents. Foods such as liquid egg can be pasteurized.

Abstract: This invention relates to an electric sauna heater comprising one or more heating resistors (1, 2) and means (3, 4) such as a time switch (3) for controlling the supply of electric power to the heating resistors, the time switch (3) comprising at least three inputs (A, B, C) the first (A) of which is connected to a first time switch contact 3A), the second (B) to a second time switch contact (3B) and the third (C) to a first terminal in a driving motor (M) for the time switch while a second terminal is connected to a counter contact (b) in the second contact (3B). In the invention, in order that the time switch could therefore be connected to two different operating voltages, a resistor (R) is connected between the third input (C) of the time switch (3) and a counter contact (a) in the first contact (3A).
