Heat exchanger for use in motor vehicle, has flow channels flowed through by fluid and designed as disk pairs, where channels comprise longitudinal sides that are connected with housing in firmly bonded manner through soldering or welding

摘要

The heat exchanger (1) has flow channels (3) flowed through by a fluid, and a housing (2) accommodating the flow channels, where the flow channels are designed as disk pairs. The housing is flowed through by another fluid, which is different from the former fluid. The flow channels have a flat cross-section and longitudinal sides (3a). The disk pairs comprise upper and lower disks that are connected with one another by a rebated joint. The longitudinal sides are connected with the housing in firmly bonded manner through soldering or welding.
