In example as shown, heat exchanger 10 comprises: first group of exchanging tube 14a, between the first collector 16 (manifold) and the second collector 18, extend, second group of exchanging tube 14b extends first group of wave-fin 22a between the second collector 18 and the 3rd collector 20, with described first group of exchanging tube 14a with the mode of alternative arrangement stacked and bonding (for example, soldering), and second group of wave-fin 22b, stacked and bonding in the mode of alternative arrangement with this second group of exchanging tube 14b.Term " snakelike ", the shape that means this fin is have peak and paddy for example wavy, sine wave, square wave, and the various modification of above-mentioned waveform.
In illustrated embodiment, the peak of wave-fin 22 and paddy are by soldering or be otherwise adhered to adjacent exchanging tube 14, and fin 22 interconnects the plurality of exchanging tube 14 on horizontal direction 24 thus.Each fin 22 further on longitudinal direction 26, (be parallel to exchanging tube 14) rather than horizontal direction 24 on extend.General expression way, " this wave-fin and this exchanging tube are stacked in the mode of alternately design, " means that each fin 22 is contained in the corresponding space 28 between two exchanging tubes, and this exchanging tube is not through this fin.Therefore, the wave-fin 22 in a space 28 be with another space 28 in wave-fin 22 be separated from each other, and heat exchanger 10 has a plurality of spaces 28, for example, the first space, second space, the 3rd space, etc.On horizontal direction 24, each space 28 is determined by two adjacent exchanging tubes 14, the separation distance 30 of being separated by between these two adjacent exchanging tubes 14, and on longitudinal direction 26, each space 28 further defines by the spacing distance 32 laying respectively between the collector of opposite end of exchanging tube 14.
In the present embodiment, the first collector 16 has entrance 34, the three collectors 20 and has outlet 36.Internal flow 38 (for example, cold-producing medium, water, ethylene glycol etc.) enters the first collector 16 by entrance 34, and this first group of exchanging tube 14a is sent to the second collector 18 by fluid 38.This second group of exchanging tube 14b is sent to the 3rd collector 20 by fluid 38 from the second collector 18, and outlet 36 is from the interior exhaust fluid 38 of the 3rd collector 20.Entrance 34 and outlet 36 can be connected to the various elements of the system that comprises heat exchanger 10.Such system, can be for example air-conditioning or heat pump, and wherein, this heat exchanger 10 can be used as evaporimeter or condenser plays a role.
Fin 22 (, fin 22a and 22b) be heat conductivity, with promote to flow through the internal flow 38 of exchanging tube 14 (be exchanging tube 14a and 14b, they are also heat conductivities) and flow through fin 22 and the external fluid of the outer surface of exchanging tube 14 (for example air) between heat transmission.Fan, bellows or some other known means can be for forcing other external fluid of air or some to flow through the outer surface of heat exchanger 10.
Although the practical structures of heat exchanger 10 may have difference, in certain embodiments, pipe 14, fin 22, collector 16,18 and 20 and lengthen member 40 (explaining after a while) and mainly by common aluminium (and/or its alloy), manufactured, and engage or bonding by common brazing material 42.In certain embodiments, at least some above-mentioned parts of this heat exchanger 10 are coated with (for example, by electroplating, the means such as coated) skim brazing material 42 (for example, coated brazing alloy on aluminium fin), so that after part is by the arrangement form assembling according to expectation, wholely (be for example assembled in controllable gas environment, the vacuum of the limit) in, be heated, until brazing material 42 fusings are flowed, subsequently parts are linked together.By the exchanging tube 14 with substantially smooth surface 44 is provided, can improve exchanging tube to the heat transmission of fin, as shown in Figure 3.
In example as shown in Figure 1, expansion safeguard construction 12 is that the first collector 16 and the 3rd collector 20 are separated between this first collector 16 and the 3rd collector 20, offer space 46.The relative motion that space 46 allows between collector 16 and 20, thus make exchanging tube 14a be greater than or less than exchanging tube 14b in the expansion of longitudinal direction 26.Space 46 also can be contained in the difference of the thermal expansion in vertical direction (vertical direction as shown in Figure 1).Thermal dilation difference in heat exchanger 10 may be when fluid 38 flows through heat exchanger 10, by the increase of the temperature of internal flow 38 or minimizing, is produced.
In order to provide some support structure in the region comprising space 46 and expansion safeguard construction 12, heat exchanger 10 has soldering or is bonded in the lengthening member 40 between these two groups of exchanging tube 14a and 14b.At lengthening member 40, be soldered in the embodiment on exchanging tube 14a and 14b, in brazing process, the supporting construction in the region at expansion safeguard construction 12 places is particular importance.Lengthen member 40 and can there are various hatch regions, as shown in Figure 4 and Figure 5.Fig. 4 shows the have tubulose hatch region embodiment of lengthening member 40a of (being similar to exchanging tube 14); Yet, lengthen member 40a and do not transmit any internal flow 38.Fig. 5 shows the embodiment of the solid bar-shaped lengthening member 40b with the hatch region that is roughly rectangle.In some instances, lengthen member 40 shorter than exchanging tube 14, because lengthen member 40, there is no need to contact with arbitrary collector.
In another example, as shown in Figure 6 and Figure 7, micro channel heat exchanger 48 comprises the first collector 50, the second collectors 52, and the 3rd collector 54.Described the first collector 50 and the 3rd collector 54 mutually dock and provide expansion safeguard construction 56 between described the first collector 50 and the 3rd collectors 54 in the mode of sliding.Compared to Fig. 6, in view of the thermal expansion of exchanging tube 14a and exchanging tube 14b there are differences, the exchanging tube 14a shown in Fig. 7 is longer than exchanging tube 14b.
In another example, as shown in Figure 8, micro-channel heat exchanger 58 is similar to the heat exchanger 10 shown in Fig. 1; Yet, in heat exchanger 58, by exchanging tube 14a being placed more near exchanging tube 14b, to omit this lengthening member 40.In order to replace lengthening member 40 and middle wave-fin 22c as shown in Figure 1, nethermost fin 22a ' is connected to the nethermost exchanging tube 14a ' of only having of uppermost fin 22b '.Heat exchanger 58 also comprises the expansion safeguard construction 60 similar or identical with 56 with expansion safeguard construction 12.In some instances, micro-channel heat exchanger 62 as shown in Figure 9, at uppermost fin 22b " in space 64 be added in expansion safeguard construction 60 as shown in Figure 8 to set up the safeguard construction 60 ' that expands more flexibly.In some cases, the formation in space 64 can be from completing by cutting fin 22b ' space, and then produce fin 22b ".In order to make the expansion safeguard construction 60 ' of heat exchanger 62 have enough flexibilities, space 64 has length 66 on longitudinal direction 26, and this length 66 is greater than the separation distance 68 between exchanging tube 14a and 14b.The length 66 in space 64 is the more than ten times of separation distance 68 preferably.In some instances, length 66 is approximately 30 times of sizes of separation distance 68.
Figure 10 illustrates the example of micro-channel heat exchanger 70, and wherein, the one or more spaces 64 on a plurality of wave-fins 22 are enough to provide expansion safeguard construction (being space 64) for heat exchanger 70.In some instances, except cut formation space 64, fin 22 is identical with other fin mentioned in this article.In Figure 10, two collectors that separate 16 and 20 are replaced by by two collectors in conjunction with the independent collector 72 with barrier sheet 74 or stopper forming, and this barrier sheet 74 or stopper are divided into two chamber 72a and 72b by collector 72.Fluid 38 enters chamber 72a by entrance 34, and first group of exchanging tube 14a is transported to collector 18 by fluid 38.This second group of exchanging tube 14b is sent to chamber 72b by fluid 38 from collector 18, and outlet 36 gives off fluid 38 from 72b inside, interior chamber.Due to the width twice of fluid 38 across heat exchanger 70, so it can be considered to a bilateral heat exchanger.
Figure 11 shows a kind of heat exchanger of single channel form.In the present embodiment, heat exchanger 76 comprises single chamber inlet header 78 and the single chamber outlet header 80 that barrier sheet 74 is not set.Exchanging tube 14 transmits fluid 38 in the single channel from inlet header 78 to outlet header 80.Space 64 (any amount of space, one or more) can be used as the expansion safeguard construction of heat exchanger.
The arbitrary examples of the heat exchanger as shown in Fig. 1 and Fig. 6-11 can be reequiped to provide the passage of any logical number.The heat exchanger going out as shown in figure 12 comprises the first collector 82, the second collector 84, the 3rd collector 86 and the 4th collector 88, and these collectors make heat exchanger 80 become the heat exchanger of threeway.Four exchanging tubes 14 on this top are transported to second collector 84 by fluid 38 from the first collector 82 as first passage, four middle exchanging tubes 14 are sent to three collector 86 by fluid 38 from the second collector 84 as second channel, and 14 of four exchanging tubes of bottom are sent to four collector 88 by fluid 38 from the 3rd collector 86 as third channel.By slit 64 ', space 90 (or being slidably connected) between collector 82 and 86, slit 64, space 92 (or being slidably connected) between collector 84 and 88 and/or the various combinations of above-mentioned all parts, can provide one or more expansion safeguard constructions.For example, slit 64 ' has wearing and tearing/jagged edges 94, to promote the heat transmission in this region.Such wearing and tearing/jagged edges can be the result of the cutting burr of conventional sawing process.
It should be pointed out that when a collector is expressed as with another collector " adjacent ", this means that these two collectors are mutually close to but not necessarily contact with each other.
