ABSTRACT:
A temperature-controlled chamber, such as an inerted oven for soldering, in which the buoyancy-induced motion of gas at the opening of the chamber is suppressed by adjusting the densities of gases. In one embodiment the inertant gas is chosen to be a mixture of inert gases such that the density of warm gas inside the oven approximately equals the density of the external atmosphere. In another embodiment, a buffer region of density-matched warm air is provided between the warm inertant inside the oven and the external atmosphere. The result is reduction in the consumption of inertant.
