A manufacturing chamber for an additive manufacturing machine comprises in an enclosure: a working plane; a manufacturing platform for the deposition of the layers of additive manufacturing material and for supporting the part being manufactured; and a circuit for circulating an inert gas flow over the manufacturing platform, characterized in that the enclosure and/or the working plane comprises an inlet opening for the gas flow, in that the working plane comprises an upstream ramp, connected to the area of the working plane where the manufacturing platform is located by a surface having a rounded convex profile, and in that the surface with a rounded convex profile is configured for attaching the gas flow, by the Coanda effect, above the working plane.

A method for producing a heat pipe comprises the following steps, performed on a first tube made from a malleable material: the diameter of the tube is swaged at a first end, and the end thus swaged is sealed closed; a second tube, of a smaller diameter than the first, is inserted into the second end of the first tube the second end of the first tube is swaged around the second tube and the interface between the two tubes is sealed the pipe thus created is partially filled with a heat-transfer fluid the air contained in the pipe is removed; and the free end of the second tube is sealed closed.

A battery pack includes a battery module having a set of battery cells and at least one cooling device. Each cooling device includes a heat collecting plate, a heat duct, and a heat dissipating element. The heat collecting plate is in contact with an outer surface of at least one battery cell of the set of battery cells. The heat duct is in contact with the heat collecting plate. The heat dissipating element has a circular orifice in which the heat duct is positioned. The heat duct contains a fluid. A connection between the heat dissipating element and the heat duct is established by tinning. A method for producing the battery pack is provided.
