Autoclave
An autoclave suitable for use for heating articles such as tires is described. The autoclave includes an elongated chamber having an interior section and an annular duct surrounding the interior section, wherein the annular duct is separated from the interior section by a dividing wall; said autoclave further including a heat source for heating the air, a fan for circulating the air in the chamber, and an air deflector mounted in a distal end of the chamber. The air deflector is positioned to redirect the airflow towards the interior portion of the chamber to eliminate air recirculation zones and improve the temperature uniformity.
1. An autoclave comprising: an elongated chamber having an interior section and an annular duct surrounding the interior section, wherein the annular duct is separated from the interior section by a dividing wall; said autoclave further including a heat source for heating the air, a fan for circulating the air in the chamber, and an air deflector mounted in a distal end of the chamber, wherein the air deflector is disk shaped having an interior surface in parallel relation to an exterior surface, wherein the interior surface faces the interior section of the chamber, and wherein the interior surface has a projection ramp extending therefrom.
2. The autoclave of claim 1 wherein the projection ramp has an angled sidewall having an angle γ in the range of 40 to 80 degrees.
3. The autoclave of claim 2 wherein the angled sidewall is circular.
4. The autoclave of claim 1 wherein the air deflector has an angled sidewall.
5. The autoclave of claim 4 wherein the angled sidewall is positioned adjacent an end of the annular duct.
