The plate portions may be rectangular, and the cooling plates may be composed of at least three plate portions. A large plate may be centrally arranged, and all plate portions may be restrained by the pipes extending through them. The heat exchanger may include side plates 10 which extend in a longitudinal direction, and which abut against plate portions. The side plates 10 arrangement may include mounting devices 20 to fasten the side plates to the housing via mounting rods 18, and the plate portions may also include devices 32,33,34 for attachment to the side plates. The heat exchanger may be used to cool a gas, which may be air. The heat exchanger may be adapted for use on a combustion engine vehicle, in particular a diesel engine unit.
Description
- 1 Heat Exchanger The invention relates to a heat exchanger, in 5
particular a heat exchanger for cooling air, in particular combustion air for an engine. The invention further relates to a heat exchanger for combustion engines in installations, such as power stations, or larger vessels or vehicles, such as for instance 10 seaworthy ferry boats. The heat exchanger according to the invention can be designed as charge air cooler.
For reasons of efficiency in building-in and occupation of space it may be desirable that the housings for the heat exchangers are designed having a 15 (circular) round cross-section. On the pipes for the cooling medium purely rectangular cooling plates or rectangular cooling plates having round end sides have been arranged. The latter cooling plates are in a relatively extensive contact with the housing, as a 20 result of which vibrations may result in increased wear.
The rectangular cooling plates result in a limited pipe occupation of the cross-section of the housing.
It is an object of at least the preferred embodiments of the invention to provide a heat 25 exchanger, particularly as air cooler, which achieves an increased efficiency within the same inner dimensions of a round housing, in particular of a housing having a circular cross-section.
It is a further object of the invention to provide 30 a heat exchanger, in particular as air cooler, which is simple to assemble.
From one aspect of the invention, there is provided a heat exchanger comprising an elongated housing, a group of parallel pipes placed in the housing for 35 passing a cooling medium therethrough, on which pipes a series of cooling plates have been arranged for cooling a medium to be cooled in the housing, the housing having
J - 2 a round cross-section and the cooling plates having a geometry composed of several plate portions.
From another aspect, there is provided a heat exchanger comprising a housing, a group of parallel 5 pipes placed in the housing for passing a cooling medium therethrough, on which pipes a series of cooling plates have been arranged for cooling a medium to be cooled in the housing, the housing having a round cross-section and the cooling plates having a circumferential edge 10 that is stepped.
Thus a larger portion of the round cross-section of the housing can be used for pipes, whereas the influence of vibrations can remain limited.
Preferably the plate portions are rectangular, so 15 that in a simple manner an optimal surface occupation can be composed. Preferably the plate portions are at least partly of a different size, for optimal adjustment to the cross-sectional form of the housing.
Preferably the cooling plates have a geometry 20 composed of at least three rectangular plate portions of a different size. The cooling plates can then comprise a relatively large rectangular plate portion that is situated centrally and smaller rectangular plate portions connecting to its long sides, in which way in a 25 simple manner a useful surface enlarged in two diametrical directions can be obtained.
The cooling plate portions can be formed integrally with each other. Alternatively the cooling plates can be composed by joining said in particular rectangular 30 plate portions. Making the heat exchanger, particularly the joining of the pipes and cooling plates, is particularly facilitated when the plate portions are loosely joined, i.e. placed adjacent to each other without immediate mutual connection. The plate portions 35 then can be kept at their places by the pipes extending through them.
Preferably the smaller plate portions are equal in
- 3 dimensions. In a particularly preferred embodiment the central plate portion itself is formed by two rectangular plate portions, placed adjacent to each other, and which in 5 dimension is (are) equal to the smaller plate portion(s). All plate portions can be taken from the same web of material, which not only offers advantages as to production, but also makes an easy adjustment to the cross-section to be occupied possible.
10 Preferably the housing cross-section is circular.
The vertices of the cooling plates preferably are situated at least near the inner circumference of the housing. According to a further aspect of the invention, the 15 efficiency of the heat exchanger can be increased when the cooling plates abut over at least two opposite portions of their circumference against side plates extending in longitudinal direction of the housing. When the aforementioned central plate portion is present, it 20 is preferred that the central plate portion abuts the side plates with its short sides. The side plates then ensure passing through and thus concentration of the medium to be cooled to the area of the pipes.
In particular when the heat exchanger is adapted 25 for cooling a gas, in particular air, it is advantageous when the side plates are positioned for bounding the space between the cooling plates in a direction substantially transverse to the flow direction.
Preferably the gas flow direction is downwards.
30 The assembly of the heat exchanger is further simplified when the side plates are each provided with an accommodation space for a mounting rod, which rod extends in longitudinal direction of the housing and has been provided with first holes for attachment means, the 35 side plates being provided with second holes in the side plates coinciding with the first holes, which second holes coincide with third holes in the housing, the
- 4 - attachment means extending through the first, second and third holes for attachment of the said mounting rod and thus the side plate to the housing.
The mounting of the package of cooling plates in 5 the housing is further facilitated by a number of partitions spaced apart in longitudinal direction, having a contour comparable to the one of the cooling plates, whether or not assembled, and being provided with holes for passage of the pipes, the partitions 10 being provided with means for attachment to the side plates. From a further aspect the invention provides a heat exchanger having an elongated housing, a group of parallel pipes placed in the housing for passing a 15 cooling medium therethrough, on which pipes a series of cooling plates have been arranged for cooling a medium to be cooled in the housing, the housing having a round cross-section and the cooling plates abutting at least over two opposite portions of their circumference 20 against side plates extending in longitudinal direction of the housing.
Preferably the cooling plates have a geometry with opposite straight sides, the side plates abutting those sides. As already stated when the heat exchanger has 25 been adapted for cooling a gas, in particular air, the side plates can be advantageously positioned for bounding the space between the cooling plates in a direction substantially transverse to the flow direction. 30 Now as well the side plates can each be provided with an accommodation space for a mounting rod, which rod extends in longitudinal direction of the housing and has been provided with first holes for an attachment means, the side plates being provided with second holes 35 in the side plates coinciding with the first holes, which second holes coincide with third holes in the housing, the attachment means extending through the
- 5 - first, second and third holes for attachment of the said mounting rod and thus the side plate to the housing.
Preferably the heat exchanger comprises a number of partitions spaced apart in longitudinal direction, 5 having a contour comparable to the one of the cooling plates and being provided with holes for passage of the pipes, the partitions being provided with means for attachment to the side plates.
The invention further provides a heat exchanger 10 according to the invention, adapted as (charge) air cooler for a combustion engine.
The invention furthermore provides an installation, such as a power station, provided with one or more engines having a heat exchanger according to the 15 invention. The invention further provides a vessel provided with a combustion engine, in particular a diesel engine, a heat exchanger according to the invention being placed between an air inlet and the combustion spaces.
20 The invention further provides a vehicle provided with a combustion engine, in particular a diesel engine, a heat exchanger according the invention being placed between an air inlet and the combustion spaces.
The invention will be elucidated on the basis of an 25 exemplary embodiment shown in the attached drawings, in which: Figure 1 shows a cross-section of a first embodiment of a heat exchanger according to the invention; 30 Figure 1A shows a detail 1A in figure 1; Figure 2 is an exploded side view of the heat exchanger of figure 1, with parts that have been left out; and Figure 3 shows a schematic isometric view of a part 35 of the heat exchanger according to figure 1.
The heat exchanger 1 in this example is a charge air cooler for use for instance with a diesel engine of
- 6 a ferry boat, by which means air is cooled prior to it entering the combustion spaces.
The heat exchanger 1 comprises a cylindrical housing 2 having a straight circle-cylindrical housing 5 portion 2a and a housing portion 2b situated on it. The housing portion 2b forms an inlet/distribution space for air to be cooled, with a distribution partition 5 provided with holes situated at the entrance. At the location of the passage 5 extending in longitudinal 10 direction the housing portion 2b changes into housing portion 2a. At the lower side, housing portion 2a has an outlet 3 for the cooled air. By means of flanges 40, the housing 2 is attached to a cylinder block of an engine that is not shown, in order to discharge the 15 cooled air to the engine.
In the straight circle-cylindrical inner space of the housing 2a a series of assembled cooling plates or segments 7 have been placed, as can also be seen in figures 2 and 3 (please note that in figure 2 the 20 portions 7b have been left out). Said (for instance copper) cooling plates 7 are rather thin (for instance 0.15 mm) and have been provided with holes 8, through which pipes 50 (figure 3) extend by which means a cooling medium can be passed through the heat exchanger 25 1. The assembled cooling plates 7 between them define a passage space for air, which descends from the direction A, and goes in between the cooling plates 7 in the direction B. to escape downwards in the direction C. The cooling plates 7 have been built up from two 30 long rectangular plates 7a and two shorter plate portions 7b placed on either side of them. The arrangement is symmetrical and as can be seen four steps 9 have been formed in the circumferential edge of the cooling plates 7, in which the plate portions 7b because 35 of their shorter length are able to extend rather far in a direction perpendicular to their length. As a result a large surface area for the cooling plates 7 can be
- 7 realised. The cooling path B can be longer as a result.
The width of the plate portions 7a and 7b is equal, as a result of which they can be cut from the same web of plate material that has been provided with holes 8.
5 As can also be seen in figure 3 the cooling plates are placed in a direction perpendicular to the passage direction B against side partitions or side plates 10 extending in longitudinal direction of the housing portion 2a, which partitions or plates 10 for instance 10 have been manufactured of weldable material such as steel and which at the lower side form a step 11, which with respect to the longitudinal edges of the plate portions 7a leaves an axial space 13 free. At the upper end the side plates or side partitions 10 have been 15 continued beyond the upper edge of the plate portions 7b, as more clearly shown in figure 1A. The side partitions 10 here are turned to the inside at an angle of approximately 45 into edge strips 15, in which at its inner side Z- or L- shaped steel brackets 17 have 20 been attached (for instance by welding), which can extend continuously in axial direction of the housing portion 2a and form an accommodation space 16 for continuous mounting rods 18. Below the brackets 17 the axial spaces 12 have been left free. At regular 25 distances along their length the mounting rods 18 are provided with holes 19 that are broadened at their entrance. The holes 19 come to lie in line with larger holes 20 that have been provided in the edge strip 15 of the 30 side plates 10, as can also be seen in figure 1A. In there it can also be seen that the housing 2a at that location has also been provided with holes 21, which come to lie in line with the holes 19 and 20. In said holes schematically shown bolts 22 can be inserted.
35 In figures 2 and 3, it is shown how the assembly of pipes 50 and cooling pipes 7 has been attached to the side plates 10. Here use is also made of mounting or
- 8 support plates 30, which just like the cooling plates 7 have been provided with holes 31 for clamping passage of the pipes 50, and have a comparable circumferential shape having a (notional) central plate portion 30a 5 forming a large rectangle and two smaller plate portions job, in this case formed integrally with it. The support plates 30 in fact form relatively thick ribs of for instance copper, which have been placed at intermediate distances of 30 cm.
10 At the edges the support plates 30 have been provided with protruding lips 32, which have been provided with cut-ins 33 extending from their upper and lower side.
The side plates 10 have been provided with vertical 15 slits 24 in which the lips 30 can be inserted. The attachment of the support plate 30 to the side plate 10 then takes place by bending to different sides of the lip portions 34, as schematically shown in figure 2.
After bending the lips 34, the slits 24 are further 20 sealed by means of a suitable putty.
During mounting, the pipes 50 and a series of pairs of cooling plate portions 7a and 7b secured to them and intermediate plates 30 form a unit that can be slid in into the housing portion 2a as one whole. The plate 25 portions 7a, 7a, 7b and 7b are kept in their correct positions by the intermediate plates 30. The mounting rods 18 are accommodated in the accommodation spaces 16 for them. After sliding in the said unit in the housing portion 2b, a fitting pin at a selected position ensures 30 correct alignment of the holes with respect to each other, and bolts 22 are placed from the outside in the holes 19-21. In this way the mounting rod 18 and thus the side plate 10 in question is clamped against the inside of the housing portion 2a, in which way the 35 assembly of pipes 50, cooling plates 7, partitions 30 and side plates 10 is fixedly attached in the housing 2.
