The present invention relates to a water heating system (part number lacubucci HF Aerospace AS0012480) for beverage dispensing machines. The heater has a double system: a pre-chamber, preferably of the spirally wound type, for pre-heating the water along a predefined path, and a chamber which is always full of water heated with resistors making direct contact with the water (or in some cases with a protection jacket) for maximizing the efficiency.

A fluid-heating device for heating fluid includes a heater unit configured to have a heater and a heating portion, the heating portion being formed as to cover surrounding of the heater, wherein the heating portion has an inner heat exchange surface formed on an inner surface of a through hole penetrating through an inner side of the heater and an outer heat exchange surface formed on an outer-wall portion of an outer side of the heater, the inner heat exchange surface being configured to perform heat exchange with the fluid, and the outer heat exchange surface being configured to perform the heat exchange with the fluid.

An instant tube heater for heating flowing liquid is disclosed that includes at least a hollow heating tube, an inlet connector, an outlet connector, and a temperature sensor. Also disclosed is a beverage preparation machine that includes the instant tube heater.

Disclosed is a water supply system that conditionally fills with heated water. The water supply system has a water tank configured to store and supply heated water, a heater configured to heat water in the water tank, and a sensor configured to sense a temperature of the water in the water tank. In accordance with an embodiment of the disclosure, the water supply system has a water supply unit configured to selectively supply heated water or unheated water to the water tank based on the temperature that has been sensed. In some implementations, this is performed to reduce use of the heated water, which may result in energy savings.

An electrical heating device comprising a support and a heating layer made of carbon fibre composite on the support mid connected to an electrical power supply to warm the device. The heating layer has a volume which comprises an electrically conducting circuit part which extends along at least one continuous line, and an electrically non-conducting insulation part which fills the remainder of the volume of the heating layer.

A heat exchanging device includes a fluid distribution/integration part for distributing/integrating fluid flowing in or out; a fluid pipeline plate coupled to the fluid distribution/integration part and in which a fluid pipeline is formed such that at least one pipeline is branched into a plurality of pipelines on the basis of a flow rate per unit area in a plurality of plates, and each of the branched pipelines is re-branched in at least one or more stages on the basis of the flow rate per unit area; and a micro-pipeline plate including a pipeline in a straight direction, which corresponds to each of the pipelines branched in a final step of the fluid pipeline plate in the plurality of plates. The fluid distribution/integration part and the fluid pipeline plate are characterized by being formed symmetrically with respect to the micro-pipeline plate.

A dispenser includes: a tank; an inlet pipe connected to the tank and to supply liquid to the tank; a heater for heating liquid in the tank; an inverter printed circuit board for controlling the operation of the heater; a heat sink formed of a metal or other heat conductive material, and having a cavity; and a power semiconductor element electrically connected to the inverter printed circuit board to control power to the heater, and fixed to the heat sink to heat-exchange with liquid flowing in the cavity. The cavity of the heat sink may receive a section of the inlet pipe or may form a flow path to receive the fluid from the inlet pipe.

An embodiment discloses a fluid heating heater including: a main body including a plate-shaped partition part, and a flow path forming part forming a flow path in the other surface of the partition part; a heating plate disposed on the flow path forming part in a plate shape, and including a heating pattern having a shape corresponding to the flow path; a circuit board disposed on one surface of the partition part; and a bus bar configured to electrically connect the heating pattern and the circuit board.

A heated sleeve for providing temperature control for a sleeve is disclosed. The sleeve comprises a water-resistant exterior shell; a thermally-insulating interior lining; a micro-controller disposed between the interior lining and the exterior shell; a temperature sensor disposed between the interior lining and the exterior shell and in communication with the micro-controller; a heating element disposed between the interior lining and the exterior shell; and a power source assembly providing power to the micro-controller and to the heating element. Temperature is provided by monitoring temperature of an interior of the sleeve.

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.
