Rapid cycle treatment oven |
摘要 |
The invention provides an oven which can be used to rapidly heat and cool a workpiece. In one embodiment, the oven includes a first duct which defines an initial leg of an enclosed air flow path and which has an inner panel and a heat exchanger. This first duct has an inlet end and an outlet end, the inlet end of which is connected to a temperature-controlled air supply. The oven also includes a second duct which defines a final leg of the enclosed air flow path and which has an inner panel spaced from the first duct's inner panel to define an oven cavity. The oven also has a connecting conduit connecting the outlet end of the first duct to the second duct and which defines an intermediate leg of the enclosed air flow path. In a preferred embodiment, the first duct is the lower of the two ducts and includes a plurality of holes through at least the inner panel of the duct. A plurality of selectively actuatable lifting pins extend through these holes in the first duct and the pins are adapted to lift a workpiece upwardly off of the inner panel.
