Abstract
A fluid flow cartridge for seating in an opening into a microwave heating cavity comprises a tubing support having an electrically conductive surface dimensioned to substantially close that opening and an elongated bobbin portion projecting from that surface. The cartridge also includes a selected length of tubing wound around the bobbin portion to form a coil, opposite end segments of the tubing extending from the coil through the conductive support surface and away from said support. Preferably, the coil has straight tubing segments on opposite sides of the coil spaced apart one quarter wavelength or integral multiple thereof at the operating frequency of the heating cavity.
