Definitions
- the invention relates to a heat exchanger block, in particular for off - highway Motor vehicles, consisting of several heat exchangers, each with two Collecting boxes, which have narrow and longitudinal walls, and with between the Collecting boxes arranged flat tubes and corrugated fins, wherein the heat exchangers in the area of the narrow walls of their collecting tanks by means of a fixing element, which extends through matching holes, are detachably connected.
- a heat exchanger block is for example from the European patent application 0 515 924 A1.
- the heat exchangers of the block are not closer shown screwed together.
- the collecting box for the Coolant cooler is integrated in the collecting box for the oil cooler.
- a solvable Assembled heat exchanger block is advantageous because the detachable connection the heat exchanger can be relatively stable and therefore no further Frame parts, rails or the like, for connecting the heat exchanger required are.
- the object of the invention is to design the heat exchanger block in such a way that that with only little effort to change its universality in terms of Use for motor vehicles with by different requirements required different sizes of heat exchangers is improved, without to lose his compact training.
- At least two corresponding narrow walls or sides of the headers have a gradation that gradation from a projecting part and a receding part is that the Grading of the narrow side of a collecting tank with the grading of the narrow side of the adjacent header box matches that in the projecting part a collecting box and in the projecting part of the adjacent
- Each collecting a bore is attached, of which at least one as Through hole is formed, and that the holes are aligned such that they can receive a fastener.
- the longitudinal walls of Collection boxes of at least one heat exchanger means for fixing a Fan cover provided.
- the matching gradations on the narrow sides of the collection boxes ensure the assembly of different heat exchangers, the Although about its tube length should be about the same size but in terms of Block depth and in particular the block height may have different sizes.
- the invention thus provides a somewhat standardizable system Available, with which the cost of manufacturing heat exchanger blocks for whole different applications can be kept low. Because no Support frame or similar mounting rails are necessary, is the Heat exchanger block extremely compact and space-saving design.
- fastening member on the entire narrow side of the two manifolds extends and that both Holes are through holes, which are formed as slots whose
- the heat exchanger block is preferably as a cross-flow heat exchanger block is formed, wherein the collecting boxes arranged on two vertical alignments are.
- the gradations are formed and the through holes so are attached, that the fastening member in each block depth direction can extend.
- the step of gradation is parallel to one vertical plane leading from the flat tubes and corrugated fins of the heat exchangers is formed.
- the heat exchangers of the heat exchanger block are with their Collection boxes arranged at least in a common vertical plane to a fan hood cheap to install the headers can.
- flat flanges can be used the narrow walls simply joined together and by means of a screw, which is designed as a sliding seat connection to be connected.
- the figures show a heat exchanger block for motor vehicles in off-highway Area, such as B. for a construction machine or for an agricultural machine.
- the collecting boxes 4; 5 are aluminum castings. However, not all collection boxes of the block must be designed as castings.
- the adjacent, corresponding narrow walls 6 of the two headers 4 of the two heat exchangers 2, 3 have a gradation thirteenth
- This gradation 13 of the narrow side 6 of a collecting box 4 fits with the gradation 13 on the narrow side 6 of the adjacent header 4 form-fitting together.
- the bores 9 are attached in the projecting portions 13a of both gradations. 13 In these holes 9 , a fastening member 8 is arranged.
- the gradation 13 is further formed so that it does not protrude beyond the outer contour of the headers and thus the block.
- the longitudinal wall 7 of the collecting tanks of at least one heat exchanger means 70 for fixing a fan hood 20 are arranged in the longitudinal wall 7 of the collecting tanks of at least one heat exchanger means 70 for fixing.
- a fan hood 20 are arranged in the longitudinal walls.
- the longitudinal walls are 7 in a common vertical plane to make the fan cover 20 easier, or to dispense with the provision of shims can.
- the support arms 25 carry a flange plate 30 to which a fan, not shown, is to be fastened.
- the lower holding arm 25 is in the embodiment shown a U-shaped bent tube while the upper holding arm is bent only L-shaped.
- the means 35 can be made available as a means 70 at the same time, so that one of the means can be dispensed with.
- the holder name 25 could also be fastened by means of the fastening elements 8 , so that the fastening elements 8 is assigned an additional function, which leads to the omission of separate fastening means 35 for the retaining arms 25 .
- FIG. 2 - 6 show the details of the connection of the heat exchanger of the block of FIG. 1.
- a gradation 13 is provided with a projecting portion 13a only for connection of the collecting tanks of the middle with the collecting tanks of the lower heat exchanger.
- the middle heat exchanger is equipped with the upper heat exchanger with another releasable connection, each having a flange 40 on the narrow side 16 of the headers, in which bores are also arranged to introduce a fastening member 50 can.
- This attachment member 50 is formed as a so-called sliding seat to allow caused by temperature differences length expansions.
- This embodiment is particularly chosen when a heat exchanger operates in a higher temperature range than the adjacent heat exchanger. This is often the case for intercoolers.
- this (possibly) known connection ensures on the one hand that the screwing forces do not exceed certain limits, in order not to obstruct the free expansion, and on the other hand, the screw connection is so strong that it does not loosen even under operating conditions.
- a corrugated washer is provided, the corrugation provides a spring force, similar to a spring ring.
- the head of the screw 50 is supported on a sleeve 53 provided with a collar through which the shank of the screw 50 extends. Below the collar of the sleeve 53 is the aforementioned corrugated washer 51. (See also enlarged view in Fig.
- fastening members 50 extend in the direction of the height of the heat exchanger block and the fastening members 8 in the direction of the depth of the heat exchanger block, ie transversely to the first-mentioned fastening members 50 .
- the holes 9 are formed in the protruding parts 13a of the step 13 as slots.
- the larger diameter of the elongated hole 9 extends vertically and in the corresponding gradation 13 of the narrow wall 6 of the lower header 4 of the heat exchanger 3 horizontally.
- Heat exchanger 1 is for example a charge air cooler
- the middle heat exchanger 2 may be an oil cooler
- the lower heat exchanger 3 may be a coolant radiator, which does not necessarily work in the same temperature ranges.
- the solution has been modified so that only on one side of the heat exchanger block, the proposed connection with gradations 13 , 8 holes and mounting member 9 was selected in the narrow walls 6 .
- the narrow walls 16 were formed so that the connection can be made solely by positive engagement.
- the illustrated positive connection 90 often referred to as a "dovetail connection", is merely exemplary. It could, for example, be designed in another suitable manner depending on the temperature-induced changes in length.
- the flat tubes 10 and the corrugated fins 11 of the heat exchangers can be seen more clearly than in the other figures.
- the heat exchanger block described above has best functional properties for use in the off - highway area. It is particularly inexpensive to produce, and it can be relatively easily modified. It should not go unmentioned that the storage of the heat exchanger block in the motor vehicle is carried out by means of directly arranged on the manifolds 4, 5 damper 17 , as shown for example in FIG. 1.
