Abstract
Techniques regarding a fan friction oven are provided. For example, one or more embodiments described herein can regard an apparatus comprising a processing chamber in fluid communication with a heating blower and a circulation blower. The heating blower can heat air adjacent to the processing chamber by fan friction. Also, the circulation blower can circulate the air heated by the heating blower into the processing chamber.
Claims8
An oven, comprising:
- a processing chamber in fluid communication with a heating blower, wherein the heating blower heats air by fan friction, and wherein a temperature of the air in the processing chamber is modulated by a varying speed of the heating blower, and wherein a portion of air exiting the processing chamber is recirculated to the processing chamber without being reheated by the heating blower;
- and
- a circulation blower that circulates the air heated by the heating blower into the processing chamber, wherein an axis of rotation of the heating blower is parallel to an axis of rotation of the circulation blower and wherein the axis of rotation of the heating blower and the axis of rotation of the circulation blower are vertical relative to an orientation of the oven.
