Abstract
An ohmic heater for the heating of a conductive fluid is comprised of a number of selectable electrodes, arrayed in such a way as to form a single pass-through from inlet to outlet. A series of flow conduits are provided to direct the flow across the faces of adjacent electrodes. The flow conduits are further configured such that the flow path makes multiple passes across the same adjacent set of electrode faces.
Claims20
A liquid heater assembly comprising:
- a housing defining a cavity, the housing having an inlet port and an outlet port;
- a heating core received within the cavity and including a first electrode, a second electrode, and a first spacer formed of a dielectric material positioned between the first electrode and the second electrode, each of first electrode and the second electrode having planar faces, the first spacer positioned between and engaged with the planar faces of the first electrode and the second electrode to define a first fluid conduit between the first electrode and the second electrode in communication with the inlet port and the outlet port, wherein the first fluid conduit defines a tortuous path in communication with the planar faces of the first electrode and the second electrode;
- and
- control circuitry electrically coupled to the first electrode and to the second electrode, the control circuitry adapted to receive and distribute electrical power and control signals to the first electrode and to the second electrode.

A liquid heater assembly comprising:
- a housing defining a cavity, the housing having an inlet port and an outlet port;
- a heating core received within the cavity, the heating core including a plurality of electrodes and a plurality of spacers stacked in alternating fashion within the cavity of the housing, each of the plurality of electrodes having planar faces, each spacer of the plurality of spacers positioned between confronting planar faces of adjacent electrodes of the plurality of electrodes, wherein the confronting planar faces of each of the adjacent electrodes of the plurality of electrodes and each spacer of the plurality of spacers define a fluid conduit that defines a tortuous path that communicates with the inlet port and the outlet port;
- and
- control circuitry electrically coupled to the plurality of electrodes to receive and distribute electrical power and control signals to the plurality of electrodes.

An ohmic liquid heater, comprising:
- a plurality of planar electrodes spaced apart along a stacking dimension, the plurality of electrodes including a first electrode and a second electrode adjacent to one another with a space defined between opposing planar faces of each of the first and second electrodes;
- and
- a structure defining a liquid flow channel passing through the space between the first and second electrodes, the structure being configured such that, when a liquid is flowing through the liquid flow channel along a flow direction, the liquid makes contact with the faces of the first and second electrodes;
- wherein the liquid flow channel defined by the structure follows a tortuous path along a central plane disposed between the planar faces of the first and second electrodes, the path changing directions a plurality of times within the central plane so as to define a plurality of sequential portions of the liquid flow channel along the flow direction that pass along respective portions of the first and second electrodes.
