Abstract: A tube for a heat exchanger defining a fluid circulation channel is disclosed. The channel extends along a longitudinal direction and includes a first flat wall including at least one pair of disturbance elements. The pair of disturbance elements is formed by a first and second disturbance element. The first and second disturbance elements are formed by a local deformation of the first flat wall toward the inside of the tube. The first and second disturbance elements extend between a first base and a first crest and between a second base and a second crest respectively. The first crest has an elongate shape along a first straight line and the second crest has an elongate shape along a second straight line. The first straight line intersects the second crest. The first and second crests have the same length measured between the two free ends of the crests.

Abstract: A heat treatment module for a heat treatment system of a vehicle is disclosed. The heat treatment module includes a first heat exchanger, a second heater, and an internal heat exchanger. The first heat exchanger and the second heat exchanger both are configured to create an exchange of heat between a refrigerant and a heat transfer liquid. The internal heat exchanger is configured to create an exchange of heat within the refrigerant, which in heat treatment system is subjected to two different temperature levels. The heat treatment module includes an expansion member that is at least secured to the first heat exchanger and/or the second heat exchanger.

Abstract: A heat exchanger for a refrigerant loop is disclosed. The heat exchanger includes a heat exchanger surface, a first refrigerant header, and a second refrigerant header which are positioned respectively at a first longitudinal end of the heat exchange surface and at a second longitudinal end of the heat exchange surface. At least one of the refrigerant headers is divided into a first collecting chamber and a second collecting chamber which are separated by a dividing wall. Each of the collecting chambers respectively includes a fluid inlet portion and a fluid outlet portion. A connecting device associated with the at least one refrigerant header includes a refrigerant inlet duct divided into a first fluid inlet channel and a second fluid inlet channel. The refrigerant header also includes a refrigerant outlet duct making the connection between a first fluid outlet channel and a second fluid outlet channel.

Abstract: A heat treatment module for a heat treatment system of a vehicle is disclosed. The heat treatment module includes a first heat exchanger, a second heat exchanger, and an internal heat exchanger. The first heat exchanger and the second heat exchanger both are configured to bring about an exchange of heat between a refrigerant fluid and a heat transfer liquid. The internal heat exchanger is configured to bring about an exchanger of heat between the refrigerant fluid, which is subjected to two different temperature levels in the heat treatment system. The heat treatment module includes an accumulation device configured to contain the refrigerant fluid. The internal heat exchanger includes a platform on which the accumulation device is disposed.

Abstract: A plate heat exchanger that includes a first, second, and third heat-exchange compartment is disclosed. The heat-exchange compartments include circulation paths in which heat-transfer fluids circulate. The heat-exchange compartments are fluidly connected to allow the heat-transfer fluids to circulate between them. The first and second heat-exchange compartments are stacked. The first and third heat-exchange compartments are arranged side by side.

Abstract: The invention relates to a device for admitting inlet gases and/or recirculated exhaust gases into an internal combustion engine cylinder, the device comprising a duct designed to supply said cylinder with inlet gases and/or with recirculated exhaust gases, characterized in that said device further comprises, in the duct, a flow control means that can be operated between a first position in which said duct supplies the cylinder with the inlet gases and a second position in which said duct supplies the cylinder with the recirculated exhaust gases. It also relates to the intake module and to the engine equipped therewith.

Abstract: A control device for a flow of intake gas and/or recirculated exhaust gases in a cylinder of an internal combustion engine, and for an intake module comprising at least one pipe which is arranged so as to supply the cylinder is disclosed. The control device comprises a means for sealing, and a means for deactivating at least one pipe which is able to be controlled between a first position in which the pipe supplies the cylinder with the intake gases (F) and a second position in which the pipe supplies the cylinder with the recirculated exhaust gases. The means for sealing is configured so as to be displaced as a result of the difference in pressure between the intake and the exhaust on both sides of the means for sealing between a locked position of the means for deactivating in the first position, and a position of release of the means for deactivating.

Abstract: A heat exchanger is disclosed. The heat exchanger has a heat exchange assembly which defines first circulation channels for the circulation of a gas to be cooled and second circulation channels for the circulation of a cooling liquid, and two gas intake and gas outlet collectors, respectively, which are assembled on two open faces of the heat exchange assembly, respectively, in which the first circulation channels open. A first collector is crimped to the heat exchange assembly and a second collector is soldered or welded to the heat exchange assembly.

Abstract: A system for the recirculation of exhaust gases is disclosed. The system includes an air intake device for an internal combustion engine with intake ducts feeding air to the combustion cylinders, each combustion cylinder including an intake duct of its own, and the intake ducts include an exhaust gas inlet orifice for exhaust gases. The system also includes a recirculation circuit for the exhaust gases, an injection rail including outlet orifices for the exhaust gases connected to the inlet orifices of the intake ducts, the connection between the inlet orifices and the outlet orifices being produced by a tapered coupling element. The tapered coupling element includes a connection tube connected to the outlet orifice of the injection rail and descending within the inlet orifice to guide the exhaust gases emerging from the injection rail within the intake duct.
