The invention relates to a heat exchanger (1), in particular, a gas cooler for a vehicle air-conditioning unit, comprising several flat tubes (2) arranged in two or more parallel rows, a collector tube (6), with one or more longitudinal separating walls (12), running along the longitudinal axis of the collector tube (6), dividing the collector tube (6) into two or more collector channels, whereby the collector tube (6) is embodied from two metal sheets (8) and openings (4) are provided in at least one of the metal sheets (8), for accommodating the ends of the flat tubes (2). Each longitudinal separating wall (12) is provided with tongue-like projections (14), arranged in grooves (16) in at least one of the metal sheets (8) and fixed on the outer side of the metal sheet (8).
摘要:
A heat exchanger which is especially used as an oil cooler in the motor vehicle industry includes interconnected plates. Outwardly closed cavities are embodied between the plates and are alternately supplied with a first or second medium by at least one supply line and one discharge line, and a corresponding medium flows through them. The plates are profiled in such a way that contact points are created between the respective profiles of the plate, and the plates are interconnected in the region of the contact points. The plates are designed such that the current from the first or second medium forming between the plates, from the corresponding supply line to the corresponding discharge line, does not follow a linear path.

A device for recycling and cooling exhaust gas of an internal combustion engine is disclosed, comprising a first exhaust-gas heat exchanger and a second exhaust-gas heat exchanger, wherein the first and second exhaust gas heat exchangers are combined in a structural unit and form a module.
摘要:
The invention relates to a cooling system for a motor vehicle comprising a first heat exchanger (1), in particular, embodied in the form of a main cooler for cooling a first liquid coolant (3) of an internal combustion engine (2) by means of an air flow coming from the ambient air and a second heat exchanger (7, 13, 407, 415) for cooling gases introduceable into the internal combustion engine, in particular, exhaust gases and/or charge air, wherein the second heat exchanger (7, 13, 407, 415) is coolable by the an air flow coming from the ambient air and is spatially separated from the main cooler (1).
摘要:
The invention relates to a heat exchanger, in particular an exhaust gas heat exchanger for motor vehicles, having tubes (3) through which a gas can flow, which are arranged in a housing casing (2) and around which a liquid coolant can flow, wherein the tubes (3) have tube ends which are held by tube bases. It is proposed according to the invention that the tubes are embodied as flat tubes (3), and that, at least one side of the tubes (3), the tube ends (3a, 3b) are flared to form an approximately rectangular cross section and can be soldered to the tube bases (7, 8).

The tie rod (10) is provided with at least one continuous hollow space which extends along the longitudinal axis thereof.
摘要:
The invention relates to a device for controlling an exhaust gas stream. Said device comprises a housing (1, 101) with at least a first, second and third connection (2, 3, 4, 102, 103, 104) that form links to a first, second and third exhaust gas conduit for conducting the exhaust gases of an internal combustion engine, a first sliding element (6, 106) with a displaceable first sliding rod (6a, 106a) and a first sealing member (6c, 106c) that is located on said rod, a second sliding element (7, 107) with a displaceable second sliding rod (7, 107a) and a second sealing member (7c, 107c) that is located on said rod and an actuator for a force-assisted actuation of the device. According to the invention, a link (4c, 104b) can be established between the first and the second connection and can be adjusted by means of the first sealing member (6, 106) and a link (3c, 103b) can be established and adjusted between the first and the third connection by means of the second sealing member (7c, 107c). The device is equipped with a control mechanism (8, 108) that is connected to the actuator, said mechanism (8, 108) permitting the first sliding element (6, 106) and the second sliding element (7, 107) to be displaced.
摘要:
The invention relates to a frame part (10) for a tubular heat exchanger. The frame part (10) according to the invention is designed for being fastened (10) to a tubular body that is constituted of a number of parallel tubes through which a heat-exchange medium flows. The tubes run at both ends into a collecting tube which extends at an angle to the tubes. The tubular heat exchanger is provided with a frame part (10) on at least one of the sides of the tubular body that runs parallel to the tubes. Said frame part occludes the tubular heat exchanger from the exterior and can be at least indirectly linked with the collecting tubes. According to the invention, the frame part (10) has at least one predetermined breaking point (20). Said predetermined breaking point (20) is configured in such a mailer that, in the case of rupture, the frame part (10) is divided into two frame sections and that in the area of the predetermined breaking point (20) a frictional connection between the two otherwise separate frame sections is established.
