Patent number: 10215502Abstract: A heat exchanger may include a block for separately conducting first and second fluids, and a box. The block may have flat tubes through which the first fluid is flowable and each of which may have a narrow tube side and a wide tube side. The box may have a base, the flat tubes being guided into the base via corresponding through-openings in the base. Each through-opening may have at least one raised edge, with at least one narrow edge side and at least one wide edge side, surrounding the corresponding flat tube. The wide edge side may be higher than the narrow edge side. The two may transition into one another via an inclination with a recess that may have a height lower than that of the narrow edge side.

Patent number: 9638476Abstract: The invention relates to a plate-shaped heat exchanger for a cooling device comprising at least one heat exchanger package, in particular for a motor vehicle, consisting of a plurality of openings for accommodating a pipe conducting a coolant, wherein each opening is surrounded by an passage and a plurality of projections are distributed between the passages for the heat exchange with the medium to be cooled. In order to allow a high performance increase of a cooling device, yet a low increase in pressure loss of the charge air, a plurality of projections are arranged around an passage, wherein the projections have a shape that assures deliberate heat conduction from the projections to the passage.Type: GrantFiled: August 4, 2011Date of Patent: May 2, 2017Assignee: MAHLE INTERNATIONAL GMBHInventors: Boris Kerler, Steffen Grözinger, Mehmet Tosun, Christian Schnepf, Florian Schmidt, Hans-Joachim Krauss, Vinko Lukcin, Stéphanie Larpent

Publication number: 20150047619Abstract: An exhaust gas radiator for at least one of an exhaust gas system and an exhaust gas recirculation system of an internal combustion engine may include an exhaust gas path, which leads from an exhaust gas inlet to an exhaust gas outlet, and a coolant path, which is coupled in a heat-transferring manner to the exhaust gas path. The exhaust gas path may have an inlet region, which includes the exhaust gas inlet and has an inlet cooling capacity. The exhaust gas path may have downstream of the inlet region an intermediate region, which has an intermediate cooling capacity that is lower than the inlet cooling capacity. The exhaust gas path may have downstream of the intermediate region an outlet region, which includes the exhaust gas outlet and has an outlet cooling capacity that is greater than the intermediate cooling capacity.Type: ApplicationFiled: March 27, 2013Publication date: February 19, 2015Applicant: Mahle International GmbHInventors: Tobias Fetzer, Boris Kerler, Lisa Von Rabenau
