摘要： This disclosure relates to a multi-planar heater element for use in a high-speed oven with a new tensioning system. Disclosed subject matter includes a radiative heater for use in a high-speed oven formed from two or more planar heater elements stacked closely to form an effective single element and allowing for extended life through the minimization of concentrated eddy currents in both elements. The disclosure further includes structures to install and remove various planar heating elements without any external tools.

摘要： The present teachings disclose a wire mesh heater including: a wire mesh element having a surface area including a non-contact area and a contact area along at least 50% of a wire mesh element length; a primary conductor including a slit having a contact surface, wherein the contact area contacts the contact surface to provide an electrical connection between the wire mesh element and the primary conductor. In some embodiments, the primary conductor is welded to the wire mesh element, wherein the contact area contacts the contact surface to provide an electrical connection between the wire mesh element and the primary conductor. In some embodiments, an elastic is stretched and secured tautly under tension prior to operation of the wire mesh heater, and the elastic keeps the wire mesh element tautly under tension during operation of the wire mesh heater.
