摘要:
A device for exhaust-gas recirculation for an internal combustion engine is provided that includes a flange for attaching to a cylinder head of the internal combustion engine. Combustion air flows from a passage region of the flange directly into at least one intake duct of a cylinder, and an inlet for an inflow of recirculated exhaust gas into the combustion air is provided. The inlet for the inflow of the recirculated exhaust gas is arranged on the flange.

A heat exchanger, particularly for charge air or exhaust gas, performs heat exchange between a first fluid and a second fluid, and includes heat exchanging guides for the first and second fluids, the guides being separated from each other in a core, the core having a plurality of flow channels through which the first fluid flows, and a housing that receives the flow channels and through which the second fluid flows. The heat exchanger also includes at least one compartment lid, which is flow-connected to the flow channels, and a base that is attached to the compartment lid and that is equipped with one or more passage openings for flow channels. The compartment lid is attached to the base via one or more connections which connections are bolted connections and/or a slotted crimping.

A heat exchanger, particularly a charge air heat exchanger or exhaust gas heat exchanger, is provided for the heat exchange between a first fluid, particularly a charge air, or an exhaust gas, and a second fluid, particularly a coolant, comprising the following: heat exchanging guides for the first and second fluids, the guides being separated from each other in the core, the core having a plurality of flow channels through which the first fluid flows, and a housing that receives the flow channels and through which the second fluid flows at least one compartment lid, which is flow-connected to the flow channels, and a base that is attached to the compartment lid and that is equipped with one or more passage openings for flow channels. In order to achieve an advantageous connection of the compartment lid to the base, particularly in case the compartment lid and the base are made of different materials, the invention provides that the compartment lid is attached to the base via one or more connections as a bolted connection and/or a slotted crimping.
摘要:
The invention relates to a heat exchanger, in particular a charge air cooler or exhaust gas cooler for an internal combustion engine of a motor vehicle, having a first box (2), a second box (3) which is arranged spaced apart from this first box (2), and a plurality of pipes (12) by means of which the first box (2) and the second box (3) are fluidically connected. Furthermore, the heat exchanger has a chamber (6) through which a coolant can flow and which is arranged between the two boxes (2, 3) and through which a plurality or all of these pipes (12), by means of which the two boxes (2, 3) are fluidically connected, run. The base (10, 11) is provided with one or more through-openings (16) for receiving the pipes (12), and at least one base (10, 11) has a border (7) which points away from the pipes toward the outside and is provided with a first step (20) and a second step (21), wherein the border (7) is arranged essentially in the edge region of the base (10, 11), and the second step (22) is arranged in the region of the first step (20), radially offset from the first step (20).
摘要:
Specified is a heat exchanger for an exchange of heat between a first fluid, in particular charge air or an exhaust gas, and a second fluid, in particular a coolant, having a block for the separate and heat-exchanging guidance of the first and second fluids, which block has a number of flow ducts which can be traversed by the first fluid and a housing which holds the flow ducts and which can be traversed by the second fluid, at least one casing cover which is flow-connected to the flow ducts, a base which is fixed to the casing cover and which is provided with one or with a plurality of passage openings for the flow ducts, wherein the base is composed of at least one first base part and a second base part.
