Abstract: A propulsion assembly for a rocket includes a propellant tank configured to contain a propellant and an engine comprising a combustion chamber configured to subject the propellant to combustion and generate exhaust gases. The propulsion assembly further includes a supply circuit and an exhaust gas circuit. The supply circuit is disposed between the propellant tank and the combustion chamber, and the supply circuit is configured to supply the combustion chamber with the propellant. The exhaust gas circuit is disposed between the combustion chamber and the propellant tank, and the exhaust gas circuit is configured to convey at least part of the exhaust gases from the combustion chamber to the propellant tank to provide pressurization of the propellant tank.

Abstract: The present invention concerns a cooling element (100) of an electrical storage device (200) for a motor vehicle, comprising at least one first wall (110) extending primarily in a first plane and in which is created at least one first channel (113) and at least one second wall (120) extending primarily in a second plane and which is created at least one second channel (123), the first channel (113) and the second channel (123) being adapted to be taken by a heat transport fluid. According to the invention the first plane in which the first wall (110) extends and the second plane in which the second wall (120) extends intersect and at least the first wall (110) is configured to support the electrical storage device (200).

Abstract: The present invention consists in a thermal module (1) for a motor vehicle, comprising a main radiator (2) and at least one auxiliary heat exchanger (3, 4) mounted on the main radiator (2) by means of a junction member (13) disposed between the main radiator (2) and at least one first auxiliary heat exchanger (3), The junction member (13) is principally formed of at least two shaft bearings (14, 15) attached to the first auxiliary heat exchanger (3) and nested inside respective open flanges (16, 17) formed on one of the lateral sides (7, 8) of the main radiator (2). Secondarily, the junction member (13) carries a plurality of auxiliary heat exchangers (3, 4) fixed to one another in staggered succession and composing a thermal submodule mounted on the main radiator (2) by means of the junction member (13).

Abstract: The invention concerns an attachment device (3) for a heat exchanger (2) comprising a core (23) for exchanging heat between a first fluid and a second fluid, said core (23) being provided with collectors (21) for the first fluid, said exchanger (2) comprising a cylinder (25), said cylinder (25) and one of said collectors (21) allowing the passage of said first fluid from one to the other, said attachment device (3) comprising a body, which is set up in order to close said cylinder (25), and an extension which allows the core (23) to be secured to a holder (4). The invention also concerns a cylinder (25) which comprises such an attachment device (3), a heat exchanger (2) which comprises such a cylinder (25) and a heat exchanging module which comprises such a heat exchanger (2).
