Tire vulcanization chamber

A chamber for vulcanizing a tire that comprises filamentary load-bearing elements arranged within an internal cavity, the chamber being delimited by an upper plate and a lower plate, two beads of the tire being fastened to a circumference of the upper plate and the lower plate, an interior of the chamber having a vertical axis XX′ and horizontal axis YY′ passing through a center of the chamber, and comprising at least one heating means, a circulation blower for circulating a heat-transfer fluid, and a directing means for directing a flow of the heat-transfer fluid,

• wherein the circulation blower is arranged at the center of the chamber, at an intersection of the vertical axis XX′ and the horizontal axis YY′, so as to direct the flow of heat-transfer fluid along the horizontal axis YY′,
• wherein the directing means for directing the flow of the heat-transfer fluid is arranged at an outlet of the circulation blower, the directing means comprising a first portion comprising deflectors, each having an inlet end and an outlet end, each of the deflectors deflecting the flow of the heat-transfer fluid by an angle α, the angle α being a result of a tangency of an axis VV′ passing through the inlet end of a deflector and through the center of the chamber and of an axis DD′ tangential to the inlet end of the same deflector, and a second portion separating the flow, after being deflected, into two substantially equal half-flows by an angle β, the angle β being a result of a tangency of an axis ZZ′ passing through the outlet end of a deflector and the center of the chamber, and of an axis CC′ passing through the outlet end of the same deflector,
• wherein the heat-transfer fluid is nitrogen or air, and
• wherein the chamber does not comprise an elastic bladder.
