The separator may have a separating wall comprising a separating wall thickness, wherein a clearance fit may be present between the separating wall and the recess in response to the insertion of the separator. The separating wall may provide at least one elevation to attain an increase of the separating wall thickness in a subarea of the separator. In the insertion position of the separator, the at least one elevation may be arranged in an area of the recess. In the insertion position, a press fit may be present between the at least one elevation and the recess.

Abstract: An evaporator with a finned tube block with tubes and fins, wherein the tubes are arranged in rows and the fins are arranged between the tubes, with a first collection and distribution box and with a second collection and distribution box. Each of the two collection and distribution boxes has a bottom and a box lid. The respective bottom has openings for inserting the tube ends of the tubes of the finned tube block. The finned tube block is divided into evaporator flows to which groups of tubes of the finned tube block are assigned. The tubes of an evaporator flow each merge end-side into a box area of a collection and distribution box. The respective bottom of the collection and distribution boxes is designed with rim holes for inserting the tube ends in the openings.

Abstract: A collector tube for a heat exchanger, which may have at least one flat tube, may include a base and a cover arranged opposite one another and embodying a longitudinal duct. The base may have at least one passage having an opening for accommodating the at least one flat tube of the heat exchanger. The at least one passage may have a collar, which may extend away from the longitudinal duct. The cover may have at least one notch, which may be located opposite the at least one passage and which may be embodied for accommodating a subarea of the at least one flat tube.

Abstract: A stacked plate heat exchanger may include a plurality of stacked plates stacked on top of one another, between which a plurality of hollow spaces for two media may be alternately defined. The plurality of stacked plates may include at least two first stacked plates and at least one second stacked plate. The plurality of stacked plates may respectively include at least one first passage opening surrounded by a dome and at least one second passage opening. The at least one second passage opening of the at least one second stacked plate may be surrounded by an annular bead. The at least one second stacked plate may be arranged between the at least two first stacked plates such that the dome of a lower first stacked plate, the dome of an upper first stacked plate, and the annular bead are connected to one another and define an immersion tube.

Abstract: A heat exchanger may include a first collecting tank and a second collecting tank. The first collecting tank may include a first collecting pipe having a first collecting pipe opening for letting in a fluid and a second collecting pipe having a second collecting pipe opening for discharging the fluid. The second collecting tank may be arranged opposite the first collecting tank and may include a third collecting pipe and a fourth collecting pipe. The heat exchanger may also include a plurality of heat exchanger pipes fluidically connecting the first collecting pipe to the third collecting pipe and the second collecting pipe to the fourth collecting pipe. The heat exchanger may also include a separating wall arranged in each of the first collecting pipe and the second collecting pipe respectively dividing each into a first pipe section and a second pipe section.

Abstract: The present invention relates to a receiving box (2) for a heat exchanger (1) for receiving and fluidically supplying tube bodies (3) of the heat exchanger (1), wherein the receiving box (2) has a box body (9), which limits at least one duct (12), which is fluidically connected to receptacles (11), in which the tube bodies (3) are received. A simplified production and/or an increased mechanical stability of the receiving box (2) are/is attained in that the box body (9) forms an injection tube (17), which is separated from the duct (12) and which is fluidically connected to at least one of the at least one ducts (12) via an outlet opening (18). The invention further relates to a heat exchanger (1) comprising such a receiving box (2).
