Definitions
- the invention relates to a heat exchanger with a connecting piece between an uncooled tube and several cooled pipes according to the preamble of claim 1.
- the length of the cooled tube can be considerably shorter and thus the heat exchanger are made cheaper, if the hot medium from an uncooled tube to a plurality of cooled pipes of smaller diameter is distributed.
- Constructions are known in which a hot medium of an inlet by means of an inlet chamber to a plurality is distributed by cooled pipes, in a common Tube bottom are held. The disadvantage here, however Turbulence of the flowing medium when hitting the Tube bottom and possible tube soil erosion.
- US-A-5 816 322 is a double-tube heat exchanger described in which the double tubes on a pitch circle arranged and connected to an annular oval tube collector are.
- the double tubes are connected via a connector with a Gas supply pipe in connection.
- the connecting piece has a widening section in which guide channels are provided, which are coaxial with each one of the double tubes are arranged.
- an air-to-air heat exchanger in which a plurality of heat exchanger tubes from a common Outer jacket are surrounded.
- the heat exchangers open into one conically narrowing connecting piece.
- the invention is based on the object, the generic Heat exchanger to make such that a hot medium of an uncooled tube by means of a connector relative simple and inexpensive design low-turbulence on a Majority of cooled pipes can be distributed Simultaneous compact space-saving design while avoiding a directly flowed tube bottom.
- the heat exchanger 1 consists of several z. B. four cooled Tubes 4, whose inner diameter is less than that Inner diameter of the uncooled tube.
- the cooled pipes 4 are arranged on a pitch circle and by one surrounded cylindrical outer jacket 5.
- the cooled pipes 4 are welded into a tube sheet 6.
- At the tube bottom 6th closes in the longitudinal direction of the tubes 4 a Inlet chamber 7 for the supply of a coolant.
- the Outer wall of the inlet chamber 7 is in the axial direction one side with the tubesheet 6 and on the other side welded to the outer jacket 5.
- the cooled tubes. 4 held in a second tube sheet and by a Surrounding the outlet chamber for the cooling medium.
- the connecting piece 3 consists of a cylindrical Input section 8, whose inner diameter of the uncooled tube corresponds. This input section 8 is z. B. by welding to the uncooled tube. 2 connected. The input section 8 of the connector 3 expands on a cylindrical end portion. 9
- the space between the guide channels and the end portion 9 of the connecting piece 3 is provided with a heat-insulating Material filled out.
- the connector 3 may consist of a metallic, heat-resistant material cost-effective and cast in one piece or made as a welded construction his.
- the connector 3 described passes the hot gas low turbulence to the cooled tubes 4 too.
- the inner diameter and the contour of the guide channels 10 and the cooled tubes 4 on each other is a turbulence of the Gas excluded, and erosion of the tube sheet 6 can do not occur.
