Circulation type heater equipment

A flow-through heater includes 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 connector having a first end directly connected to the PCB and a second end including a spring in 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 to the inlet of the fluid channel for cooling. Electronic devices or components may be mounted directly on the thick film heating element. A terminal adapted for ground connection may be formed integrally with the channel plate and may be bent out of a plane of the channel plate, or may be formed integrally with the thick film heating element. 一种流通式加热器，包括厚膜加热元件和附接到所述厚膜加热元件以在其间形成流体通道的通道板。所述流体通道可以具有矩形或正方形的平面螺旋形式。PCB可以通过一个或多个连接
