Appl. No.:

11/158893

Inventors:

Jeffrey C. Mitchell - East Troy WI, US
Yougui Zhao - Sheboygan WI, US

Assignee:

International Thermal Systems, LLC - Milwaukee WI

International Classification:

F27B 7/14

US Classification:

432147, 432175, 34666, 34270

Abstract:

A convection oven that achieves a substantially enhanced degree of air flow through the use of a special nozzle design. Turbo flow air nozzles create an air flow pattern to provide higher velocity airflow with a smaller fan size and ductwork. The turbo flow air nozzles include main supply nozzles that direct high velocity air through air entrainment and mixing sections that entrain air from the oven interior to generate the increased air flow in a heat transfer zone of the oven. Appropriate ductwork is provided to direct air from a fan or fans to the supply nozzles to generate a high velocity air flow therethrough.

Abstract:

A system for heating, drying or curing an object, the system comprising a housing having a first wall and at least one second wall adjacent the first wall. The first wall and at least one second wall define an interior for holding an object to be heated, dried or cured. The system also includes an air plenum adjacent to, covering and disposed inward from the first wall, and at least one air plenum opening in the air plenum to supply air into the interior. A fan is disposed in the one air plenum opening. The system also includes a ductwork assembly adjacent to, covering and disposed inward from the second wall. The ductwork assembly is in air-communication with the air plenum, and has a ductwork opening so that substantially all air circulation in the interior is between the air plenum opening and the ductwork opening.
