A heat exchanger having a collection tank having an internal chamber and a header connected to the collection tank and receiving a number of flat tubes through apertures in the header. A reinforcing member received within the collection tank and/or the header functions to reinforce the header and/or the collection tank in applications where these elements are subject to internal pressures that would otherwise deform the header and/or collection tank to an unacceptable extent. The heat exchanger may include a curved gasket on each flat tube to match the shape of the flat tubes and a curved header. Also, another gasket can be located between a metal or plastic collection tank and a plastic or metal header, respectively, to prevent leakage therebetween.

A heat exchanger includes a plurality of tubes, a collection tank having an inlet port and an internal chamber in fluid communication with the plurality of tubes, a header coupled to the collection tank and having a plurality of apertures each dimensioned to receive a corresponding tube, a gasket separating the header from the collection tank and sealing a gap between the header and the collection tank, and a reinforcement retaining the gasket in position between the header and the collection tank. The reinforcement includes a first web extending across the internal chamber and a second web spaced apart from the first web and extending across the internal chamber. The heat exchanger also includes a baffle coupled to and extending between the first web and the second web. The baffle extends across at least a portion of the internal chamber between the inlet port and the plurality of tubes.

A heat exchanger plate for an evaporator includes a flow transverse distribution device. Disks of the flow transverse distribution device conduct the medium to be evaporated to the flow channel extending in the direction of the longitudinal axis. The disks include openings allowing a flow of the medium in the direction of the longitudinal axis with comparatively higher flow resistance than in the direction of the transverse axis. The number of disks arranged one behind the other in the direction of the longitudinal axis varies over the width of the heat exchanger plate in the direction of the transverse axis. On each width section, in which the entry of the medium into the disks arranged one behind the other is intended, the comparatively largest number of disks is provided one behind the other. As the distance from the entrance increases, the number decreases in the direction of the transverse axis.

A system and method for recovering energy from gases of an internal combustion engine in conjunction with exhaust gas recirculation is described and illustrated, and in some embodiments includes an exhaust gas recirculation valve and an exhaust gas recirculation heat exchanger, with a working medium which undergoes a cyclic process being evaporated in the exhaust gas recirculation heat exchanger by hot exhaust gases, and with resulting steam being converted into mechanical or electrical energy which is available as additional energy. To improve heat recovery with little technical expenditure, an exhaust gas control valve can interact with the exhaust gas recirculation heat exchanger, and can control the mass flow of exhaust gases flowing through the exhaust gas recirculation heat exchanger constantly in all operating phases of the internal combustion engine, approximately in the vicinity of the performance limit of energy recovery.
