Definitions
- Heat exchangers in particular intercoolers for motor vehicles
- the invention relates to a heat exchanger, in particular a charge air cooler for motor vehicles, according to the preamble of claim 1.
- Known heat exchanger consist of a heat exchanger block (or called network) and arranged on both sides collecting boxes for the entry and exit or the collection and distribution of a Cyprusü ⁇ transfer medium, z. As coolant or charge air.
- the heat exchanger block consists of mutually parallel tubes, z.
- the corrugated fins used which are soldered to the pipes.
- On the inside of the tubes in particular in the case of flat tubes, so-called internal corrugated ribs or turbulence generators are arranged to improve the heat transfer and are likewise soldered to the tube. This results in a stable internal pressure-resistant bandage for the heat exchanger block.
- the tubes open with their tube ends in tube sheets, which parts of the collecting tanks or are connected to the collecting boxes.
- the tubesheets have passages in which the tube ends are soldered.
- a similar heat exchanger was known from DE-A 198 57435.
- single or multi-row systems heat exchanger blocks
- one or more rows of tubes are separated by an air gap. arranged one behind the other.
- single-row networks are used for lower powers and double-row networks for higher powers, the latter at depths of more than about 70 mm.
- Double-row systems have several disadvantages: they are both expensive to manufacture and worse in performance. For the production two rows of tubes must be cassetted with a Maschinentube ⁇ the rib and inserted into two rows of passages in the tube sheets.
- the passages in the tubesheets must have a minimum distance in the depth direction for production-technical reasons, which also specifies the distance of the rows of tubes in the network. This air gap increases the pressure drop on the cooling air side and increases the overall depth of the heat exchanger.
- the heat exchanger block has only a series of flat tubes with a depth T that is greater than 70 mm and less than 120 mm.
- a single-row heat exchanger, in particular intercooler with such a depth in the flow direction of the cooling air brings advantages in both the production and the cost as well as in the performance.
- Known heat exchangers, in particular charge air coolers, were designed in two rows at this depth.
- the system according to the invention requires only a series of flat tubes, a continuous corrugated rib on the cooling air side and an inner corrugated rib on the charge air side. Such a system is much easier to cassett than a two-tier system.
- the tube plates only a series of passages, ie the gaps between the passages in the cooling air flow direction and between the rows of tubes omitted.
- the depth of the flat tubes is in a range of 70 to 100 mm, and particularly advantageously in a range of 80 to 90 mm.
- the depth of the flat tubes lies in a range of 90 to 120 mm, and particularly advantageously in a range of 90 to 100 mm.
- the flat tubes have a clear width in a range between 3 and 10 mm, preferably between 5 and 10 mm, in particular in a range of 6 to 8 mm, the optimum at a clear width of 7 mm is located.
- a clear width in a range between 3 and 10 mm, preferably between 5 and 10 mm, in particular in a range of 6 to 8 mm, the optimum at a clear width of 7 mm is located.
- inner corrugated ribs or turbulence inserts are arranged in the flat tubes, which are soldered to the flat tubes. This achieves the advantage of a better heat transfer and an increased internal pressure resistance for the flat tubes, which is necessary in particular at an increased depth.
- the single FIGURE shows a detail of a heat exchanger block 1, which is constructed from a (number word) series of flat tubes 2 and arranged between them corrugated fins 3.
- Flat tubes 2 and corrugated fins 3 are part of an intercooler, not shown, which cools the air (charge air) of a supercharged, not shown internal combustion engine of a motor vehicle by ambient air (cooling air).
- the charge air flows through the flat tubes 2 perpendicular to the plane of the drawing, and the ambient or cooling air flows in the direction of the arrow L between the flat tubes 2 via the corrugated fins 3, which are provided with gills 4 to improve the heat transfer.
- inner corrugated fins 5 are arranged, which form the cross section of the flat tubes 2 into a multiplicity of chambers divide and are soldered to the flat tubes 2 on the inside.
- the corrugated fins 4 are soldered to the outside of the flat tubes 2. In this respect, there is a good heat conduction from the inside of Flachroh ⁇ re 2 on the outside.
- the flat tubes 2 are - as explained at the beginning of the prior art - held in non-illustrated passages of tube sheets and soldered to them. On the tube sheets not shown collecting boxes, so-called air boxes are placed.
- the depth T, d. H. the extent of the flat tubes 2 and the corrugated fins 3 in the air flow direction L is denoted by T.
- T The depth T, d. H. the extent of the flat tubes 2 and the corrugated fins 3 in the air flow direction L.
- the inside width of the flat tubes 2 is characterized by the dimension H.
- the dimension T is in a narrower range of 80 to 90 mm, in a further range between 70 and 100 mm and in a wide range of 70 to 120 mm.
- the flat tubes 2 are vor ⁇ preferably made of an aluminum sheet and welded to the narrow side in the longitudinal direction.
- the corrugated fins 3 (cooling air fins) and the inner corrugated fins 5 (charge air fins) are made of thin aluminum sheet and are soldered to the flat tubes 2. This results in a compact, pressure-stable heat transfer block 1.
