Abstract
This disclosure relates to a micro-wave air heater which includes a generally upstanding frusto-conical air duct housing between opposite input and output end portions thereof, crossed tubular liquid conduits which open into an encirculating liquid chamber, and a plurality of micro-wave generating means externally of the liquid chamber for generating micro-wave energy for heating the liquid whereby air passing through the duct and passed the tubular conduits is heated. The liquid is self-circulating within the tubular conduits and the liquid chamber through liquid temperature gradients, and means are provided for selectively regulating the operation of the micro-wave generating means to create the liquid temperature gradients.
Claims12
A micro-wave air heater comprising a hollow air duct through which air is adapted to pass from an input end portion toward and through an output end portion thereof, a plurality of tubular conduits spanning said duct within an interior thereof between said input and output end portions, micro-wave transparent wall means externally of and in generally spaced relationship to said duct and defining therewith a liquid chamber, a liquid in said tubular conduits and said liquid chamber, and micro-wave generating means exteriorly of said liquid chamber for generating micro-wave energy for heating said liquid whereby air passing through said duct and past said tubular conduits is heated.
