10b.Two heat exchanger blocks 10a, 10b are limited by cover board (such as in the form of cover board material) 5a or 5b outward respectively outward
Boundary.
In order to supply and export heat exchange medium, it is equipped with to carry above the entrance and exit 9 of heat transfer pathway 1 and takes over
6 attached column bodily form collector 7, it is described to take over for being connected supply and derivation pipeline.The collector 7 is also referred to as collector 7 below.
By so-called distributor piece, distributor fin 2 is constituted the entrance and exit 9 of heat transfer pathway 1 in other words, is responsible for existing in medium
It is evenly distributed in single heat transfer pathway 1.Medium flows to the channel being made of fin 3 and demarcation strip 4 by heat transfer pathway 1
In.Collector 7 and take over 6 can be had been mounted on single block 10a or 10b.Alternatively, according to one embodiment
There are following feasibilities：According to the present invention after all or single collectors 7 have been fixed to one another, they are just fixed
Onto two blocks 10a, 10b.Here, to extend to two blocks 10a, 10b upper or be fixed on two blocks 10a, 10b for such as collector 7
On, to supply two blocks with medium or to take medium away from two blocks 10a, 10b (this is represented by dashed line in Fig. 1).
Fin 3 is brazed at its contact site with demarcation strip 4, is thus generated strongly between fin 3 and demarcation strip 4
Thermal conductive contact.Thus improve the heat exchange alternately flowed between the various media in adjacent hot switching path 1.
Block 10a, 10b are preferably made of aluminium, wherein these components are connected with each other by solder brazing.However it can also use
Stainless steel is as material.Fin equipped with solder flux, separate plank, distributor fin, cover board material mutually stacked each other with side slat and
Subsequent solder brazing in an oven is at heat exchanger block 10a or 10b.Next, the collector 7 with take over 6 is welded to hot friendship
On parallel operation block 10a, 10b.
It is such as obtained from Fig. 1 and Fig. 2, at least one first proximate matter 11 is fixed on the first lid of first heat exchanger block 10a
On plate 5a, wherein the first proximate matters 11 that are preferably multiple longitudinal elongations and extending parallel to each other are fixed on the first cover board 5a
On, first proximate matter vertically extends respectively herein.Equally, on the second cover board 5b of second heat exchanger block 10b
It is fixed at least one second proximate matter 12, wherein for preferably also there are multiple longitudinal elongations herein and extending parallel to each other
Two proximate matters 12 are fixed on the second cover board 5b, and second proximate matter equally vertically extends respectively.
In order to connect two heat exchanger blocks 10a, 10b, the heat exchanger block is arranged so that the first cover board and second
Cover board 5a, 5b are toward each other and parallel relative to each other so that at least one first proximate matter and at least one second proximate matter are along flat
Row is set opposite to each other in the direction R of two cover boards (and extending herein perpendicular to vertical direction), to realize at least one
Gap 15, the element 13 of longitudinal elongation and adjacent proximate matter 11,12 friction locks and preferably also shape be arranged in locking manner it is described
In gap.
Multiple first proximate matters and the second proximate matter 11,12 are preferably set (as shown in FIG. 2), wherein in this feelings
It is preferably set up under condition：Second proximate matter 12 is arranged between each two adjacent first proximate matter 11 so that in corresponding second type
Be respectively present a gap 15 between material 12 and both sides the first proximate matter 11 adjacent (along direction R), the element 13 of longitudinal elongation with
Adjacent proximate matter 11,12 friction locks and preferably also shape is arranged in the gap, and in this friction lock in locking manner
And especially also shape is cooperated in the groove 110 of the first accordingly adjacent proximate matter 11 and is cooperated to corresponding second type in locking manner
In the groove 120 of material 12 so that two heat exchanger blocks 10a, 10b are fixed to one another in turn by two cover boards 5a, 5b.It is especially real whereby
Existing two blocks cannot be moved away from each other along normal direction in the direction of two cover boards 5a, 5b.

One inner space of other limit.Correspondingly, groove 110,120 is configured on cross section (herein perpendicular to the perpendicular of element 13
Straight axis or longitudinal axis) spill (such as substantially semicircular) cavity.Equally it is contemplated that other cross section pairings.Cause
This, as shown in Figure 4, also triangular ground constructs groove 110,120 on cross section, and wherein hollow material 13 is herein in cross section
On correspondingly construct to quadrangle (such as square or rectangle).In addition, there is also the feasible of the groove saved in proximate matter 11,12
Property.Therefore, proximate matter 11,12 can for example have planar side 11a, 12a, and the element of longitudinal elongation is herein (such as by widening it
Cross section) it is anchored on by pure friction lock between the planar side, as shown in Figure 5, the wherein broadening shape of hollow material 13
State is represented by dashed line.
(as explained above) according to fig. 2, if two cover boards 5a, 5b are arranged opposite one another, element 13 ifs, is excellent
Selection of land is free unoccupied place to be directed in mentioned gap, wherein in order to the adjacent proximate matter 11 of corresponding element 13 and two,
Between 12 generate friction lock and it is also preferred that shape it is sealed, make corresponding element 13 deform.Fig. 2 is schematically shown element
13 be free unoccupied place be arranged into attached gap 15 (on Fig. 2) to element 13 is seamlessly rubbed and shape arrange in locking manner
To the transition in the gap 15 attached (under Fig. 2).Here, the outer diameter D of pipe 13 increase to bigger outer diameter D '.
Finally, Fig. 3 shows the feasibility for widening hollow material (such as pipe) or element 13, corresponding in order to generate
Friction lock or friction and shape are sealed.Here, conduit 20 is directed to correspondingly between being free unoccupied place to be arranged into and attached
In the inner space 13a of hollow material 13 in gap 15, the conduit is placed in proximate matter particular by the circular end sides flange 20a
11, on 12, wherein the slave flange 20a section 20b outstanding of conduit extend into the inner space 13a for the hollow material 13 being related to
In.The section 20b of conduit 20 is at its both ends by each one circular sealing element 23 (such as in the form of O-ring) phase
Inner space 13a sealings for corresponding hollow material 13.
Hydraulic fluid F (such as water or oil) is supplied to by transfer pipeline 24 in the channel 21 being made of conduit now, should
Channel is led in the lateral openings 22 of the section 20b of conduit 20 so that fluid F can load the interior of corresponding hollow material 13
Wall.Thus cause by the outer diameter D of the broadening of corresponding hollow material 13 to bigger ', the outer diameter of the bigger is by corresponding hollow material
13 shapes are anchored in locking manner in attached gap 15 or groove 110 and 120.The load with fluid F is preferably carried out, is made
It obtains corresponding hollow material 13 plastically to flow, so that the shape as good as possible for the proximate matter 11,12 realized and surrounded is sealed.
