Definitions

  • the invention relates to a device for heat transfer between the exhaust gas an internal combustion engine and a coolant, and in particular an exhaust gas cooler in exhaust gas recirculation to an internal combustion engine.
  • This has one of a housing wall surrounding exhaust gas inlet and exhaust area and a heat transfer area arranged therebetween. In the heat transfer area a bypass channel is integrated.
  • a control element is used for control of the exhaust gas flows through the heat transfer area or the bypass duct.
  • exhaust gas coolers are used in EGR (exhaust gas recirculation) systems that serve to reduce the emission values of the exhaust gas in internal combustion engines.
  • EGR exhaust gas recirculation
  • part of the exhaust gases are drawn into the intake manifold and then into the combustion chamber of the engine returned to the combustion temperature and thus the NOx production to humiliate.
  • the exhaust gas must pass the radiator or be bundled in such a way that cooling no longer takes place or only takes place marginally. This is achieved by means of a controllable bypass function, with the exhaust gas temporarily is redirected.
  • this bypass function is known through a separate bypass pipe to build.
  • the described EGR system includes an EGR pipe that the Exhaust pipe connects to the intake manifold of the engine.
  • this tube is an EGR cooler used, which can be bypassed with the bypass tube.
  • the exhaust gas flow is controlled by means of a valve located on the branch between the bypass pipe and the EGR pipe with an integrated cooler, the known system being none compact unit.
  • An exhaust gas heat transfer device is known from US Pat. No. 6,141,961 the exhaust gas heat is used to heat the passenger compartment.
  • the transmission facility comprises two parallel pipes, one main pipe and a bypass duct provided with a heat exchanger.
  • the regulation of the gas flow that flows into the heat exchanger is achieved by means of a flap.
  • the bypass is in the heat transfer area or integrated the cooler.
  • the heat exchanger system described serves to heat the exhaust gas during the warm-up phase of the engine to be used to adequately and quickly heat the vehicle interior deliver safely. Heat is extracted from the exhaust gas via a heat exchanger be fed to the cooling circuit of the engine, thereby heating the cooling circuit with an attached radiator for the vehicle interior to accelerate.
  • a heat exchanger comprises a housing with an exhaust gas inlet and an exhaust gas outlet area and a heat transfer area, a bypass channel being integrated in the heat transfer area.
  • a Control element which is made of a one-sided clamped and adjustable sheet exists, either the bypass duct or the heat transfer area can be sealed or intermediate positions can be set.
  • the shape of an adjustable plate is not suitable for controlling the Exhaust gas flow in one embodiment of a heat transfer area with one not Bypass close to the edge.
  • the object of the invention is to provide a device for Heat transfer between the exhaust gas of an internal combustion engine and one Coolant, especially a regulated EGR cooler, with a simple and safe working exhaust gas flow control with a compact design and independent from the arrangement of the bypass duct in the heat transfer area create.
  • the core idea of the invention is as an adjusting element for regulating the exhaust gas flow and optional exhaust gas cooling to use a ball. It is either in the exhaust gas inlet area in front of the inlet opening of the bypass duct or analogously in the exhaust gas outlet area arranged after the outlet opening of the bypass channel.
  • the flow control is done by rotating the ball between a first and a second rotating position reached.
  • the ball is constructed so that in the first ball turning position the Bypass channel is open and at the same time a flow through the heat transfer area is prevented.
  • the ball closes in the second ball slewing ring the bypass channel and allows the exhaust gas to flow through the heat transfer area to.
  • the ball has a central flow channel. This is in flow connection with the opening of the bypass channel in the first ball rotation position.
  • the flow of the exhaust gas through the spherical body prevented in or out of the heat transfer area.
  • the Ball radially in its outer sphere area, namely outside the flow channel, at least one flow area. This runs across, preferably at right angles to the flow channel. In the second rotary position, over the spherical body of the bypass channel is closed, while exhaust gas flows through the outer Flow area in or out of the heat transfer area becomes. There are also intermediate positions between these two end positions possible.
  • the ball can be produced reproducibly even with large quantities and allows safe and fast control of the exhaust gas flows.
  • the actuator is either in the exhaust gas inlet or in the exhaust gas outlet area, whereby for the Flow control only the ball and no other closure on the other End of the component is necessary.
  • the ball body In the first ball turning position, the ball body itself prevents Exhaust gas flows through the heat transfer area. This is achieved in that the spherical body on the inner wall of the exhaust gas inlet area or Exhaust outlet area comes to the plant sealing. That means at this Place the diameter of the entry or exit area in the clear diameter corresponds to the ball.
  • the respective flow areas are formed as grooves in the outer region of the ball. After a another embodiment, it is also possible that these flow areas are drilled into the ball in the outer area. It is only important that the Ball next to the central flow channel radially in an outer ball area Flow areas, for example bores or open to the outside Grooves.
  • the groove solution is further developed by grooves in the ball in this way are introduced from the outside that a spherical segment formed between the grooves, in particular a spherical center segment remains. This takes over the sealing function on the housing inner wall to prevent exhaust gas flows through the heat transfer area in the first rotational position.
  • the ball according to the invention is, for example, by mechanical processing a metallic solid sphere.
  • the grooves are from the outside in the ball milled.
  • the central flow channel is drilled into the spherical body.
  • An alternative Manufacturing is cold extrusion, where appropriate pressing the flow channel and the grooving is carried out in two steps.
  • the ball is in its rotational position before or after the bypass channel through one with the Spherical rod or shaft connected to which is also rotated.
  • the rod protrudes beyond the housing wall of the entry or exit area and is rotated by appropriate actuating means.
  • connection piece is placed on the entrance area, which the ball partially surrounds. On the other hand, it takes up the exhaust pipe. The same applies to the exhaust gas outlet area.
  • the proposed control element in the form of a ball allows flexible arrangement the bypass duct in the heat transfer area.
  • the bypass channel can be central be integrated, it can for example also close to the edge or directly on the edge of the Heat transfer area may be arranged.
  • the ball is then arranged accordingly and the space required for this by adjusting the exhaust gas inlet or - exit area created.
  • the exhaust gas cooler 1 shows an exhaust gas cooler 1 as used in an EGR system can.
  • the exhaust gas cooler 1 can be in one piece from a heat transfer area and an exhaust gas inlet and exhaust gas outlet area adjoining it at the ends, which are enclosed by a common housing his.
