  • Patent number: 9174192
    Abstract: The invention relates to a tube bundle reactor with a flat feed hood. Alternatively, the release hood may also have a flat design. The flat design reduces the heat of reaction which arises in the hood in the case of reaction types which take place not only in the tube bundle (uncatalyzed reactions and reactions with homogeneously distributed catalyst). This greatly suppresses undesired reactions which already take place in the hood owing to accumulated heat, which achieves a higher selectivity in the case of thermally sensitive reactions. In addition, the thermal distribution within the hoods can be controlled precisely. The tube bundle reactor comprises a tube bundle which has a feed end which is connected to a feed hood of the tube bundle reactor, wherein the feed hood is configured in a flat design with a cross-sectional area at the feed end and an internal volume, and the ratio of internal volume to cross-sectional area is less than 0.35 m.

  • Patent number: 8136579
    Abstract: The invention relates to a heat exchanger which is intended, for example, for a motor vehicle and which comprises a tube bundle (2) and spacers which are positioned between the tubes of the bundle in order to promote the exchange of heat. The bundle is defined by two end spacers (70, 71). The inventive exchanger also comprises two collector plates through which the ends of the bundle are intended to pass and at least one flange (50, 51) which is disposed on one or the end spacers. Advantageously, the flange comprises at least one expansion zone (80) in order to compensate for the longitudinal expansions thereof, while the transverse section of the flange in the expansion zone is essentially U shaped.

  • Patent number: 8118082
    Abstract: The invention relates to a heat exchanger (10), in particular, for exhaust coolers on internal combustion engines. The aim of the invention is to provide a separation of the carrier medium flow into two partial flows as leak free as possible, by suitable embodiment of the baffle plate (40). A heat exchanger (10), as used, in particular, as exhaust gas cooler for internal combustion engines, comprises a heat exchanger channel (14) and a bypass channel (11), whereby a switching flap (20) is arranged upstream of the heat exchanger (10) in the flow channel (25), which divides the incoming carrier medium into the heat exchanger channel (14) and the bypass channel (11). A baffle plate (40) is provided to maintain the separation between the partial flow through the bypass channel (11) and the partial flow through the heat exchanger channel (14), which, according to the invention, extends from the switching flap (20) to the beginning of the bypass channel (11).

  • Patent number: 8062605
    Abstract: A cooling system for use in a shell-type reactor includes vertically extending double tubes with an inner tube and an outer tube closed at its lower end. The system also includes a distributor for supplying a fluid cooling medium into the upper end of the inner tubes and a horizontally extending plate, which on its upper surface includes at least two upwardly open, parallel grooves. Two adjacent grooves are separated by a common inner wall. At least one outer tube, having an upper end, is disposed in each groove, through the plate. Each outer tube is tightly welded to the plate on the groove base. The upper, open side of each groove is closed with a lid, so that each groove forms a collector for discharging the cooling medium from the outer tubes. Each inner tube opens through the lid into a distributor and is tightly attached to the lid.

  • Patent number: 8020610
    Abstract: The invention relates to an exhaust gas heat exchanger in an exhaust gas recirculation arrangement. The heat exchanger includes a plate stack which is surrounded by a housing. The plate stack can include two plates which are connected at their longitudinal edges to form a flat tube which contains a turbulator through which exhaust gas flows. The heat exchanger can also include a coolant duct which is equipped with flow directing elements arranged between two flat tubes. In order to make the exhaust gas heat exchanger more resistant to changing temperature stresses, the invention provides that the flow directing elements can be formed from a corrugated plate in which ducts with inlets and outlets are formed. At least some of the ducts in the inlet area of the coolant have a nonlinear profile so that changes in length are permitted between the plate stack and the housing.

  • Patent number: 8011422
    Abstract: To provide an EGR cooler which has a small number of parts and achieves compact design with low cost. A plurality of flat tubes, each having a bottom to close an end thereof, is arranged in parallel. An opening of each of the flat tubes penetrates through a tube plate. Corrugated fins are placed in each of the flat tubes, thus forming a core. A casing encloses the outer circumferential surface of the core. The tube plate closes the opening of a tank body equipped with a partition. The edge of the partition is placed at an intermediate position in the width direction of the opening of the flat tube.
