Abstract (en)
A flow-through heater comprises a thick film heating element and a channel plate attached to the thick film heating element to form a fluid channel therebetween. The fluid channel may have a rectangular or square, planar spiral form. A PCB may be connected to the heating element by one or more connectors, each having a first end connected directly to the PCB, and a second end comprising a spring making electrical contact with the thick film heating element. An electronic device or component for switching or controlling the supply of current to the heating element may be mounted adjacent an inlet of the fluid channel, for cooling. An electronic device or component may be mounted directly on the thick film heating element. A terminal suitable for an earth connection may be integrally formed with the channel plate and may be bent out of the plane of the channel plate, or may be integrally formed with the thick film heating element.
