In the drawings in order to highlight description emphasis, eliminate the associated components in handpiece Water Chilling Units unit associated therewith or heat source unit.In view of the major design of the present invention is in that heat-exchanger rig, such omission is without influence on those skilled in the art's the understanding of the present invention and without making the imperfect of the disclosure.
Well known in the art, heat-exchanger rig includes at least one heat exchange module.It is apparent that, heat-exchanger rig of the present invention can include one or arbitrarily several (such as, two, three, five etc.) blower fan module of heat exchange module and respective numbers or fan unit, plurality of blower fan module or fan unit constitute a blower fan apparatus or blower fan system.Certainly, each fan unit or module can also be a blower fan or more blower fan.
Generally, heat exchange module includes two heat exchangers being stitched together.Certainly, those skilled in the art it is apparent that, the building form of heat exchange module is not limited to the above-mentioned type, the building form of heat exchange module can also include following several: heat exchange module can include single heat exchange unit, and its trapezoidal heat exchange side is formed by a part (two ends of the single plate heat exchanger of such as bending) for this single heat exchange unit of bending.Or, heat exchange module can also be formed by multiple heat exchange units, and wherein this trapezoidal heat exchange sidepiece is formed by single heat exchange unit, and this trapezoidal heat exchange side is mounted in other parts (other heat exchangers such as adjacent thereto) of heat exchange module.Or, heat exchange module can also include a heat exchange unit being assembled together relative to each other and a supporting member (such as metal plate support component), described heat exchange unit is bent over being formed described trapezoidal heat exchange side, and described trapezoidal heat exchange side is assembled on described supporting member.In principle, each heat exchange unit is traditional single heat exchanger, namely there are two headers and compartment of terrain and the many heat exchanger tubes (if such as flat tube, passable, flat tube can be provided with multiple fin) that extend parallel between which.Multiple heat exchanger can certainly be included.Hereinafter, in order to describe simplicity, by single heat exchange unit referred to as heat exchanger.
As described in Fig. 5-6, in the first embodiment of the present invention, each heat exchange module includes two identical heat exchangers, and namely heat exchanger 10 is identical with 20.In this heat exchange module, each trapezoidal heat exchange side is formed by the main part 15 after a heat exchanger bending.
Specifically, the heat exchanger tube 13 in bending part 16,17 is tilted and bending relative to the heat exchanger tube in main part 15 so that the plane at main part 15 place is perpendicular to or is generally perpendicular to the plane at each the bending part place in said two bending part.
For Fig. 5, illustrate that the wrap direction of the heat exchanger 10 that both sides have bending part is: first carry out the bending of flat tube 13, then carry out the body bending of heat exchanger 10.Concrete bending step is as follows: first, by the both sides (in as shown the left and right sides of flat tube) of every flat tube 13, with the width (i.e. fore-and-aft direction in the page) of this flat tube for axis, flat tube is bent into angle [alpha], and the flat tube 13 after bending is sequentially inserted in the groove (not shown) of header 11,12.Then, by adjust flat tube position, make all flat tubes 13 either side bending part substantially on one wire, i.e. on bending axis Y and Y ' as shown in Figure 5.It should be noted that form described angle beta (two bending axis Y and Y ' are identical with the distance of 12 apart from respective header 11, so that bending part 16 and 17 is equivalently-sized, description thereof in detail below) between two bending axis Y and Y '.So, heat exchanger 10 is the formation of main part 15 and bending part 16,17.Between adjacent flat tube, insert fin 14, then put soldering oven soldering into integral.Finally, by the bending part 16 and 17 in the heat exchanger after bending with bending axis Y and Y ' for bending axis, along the direction bending (namely heat exchanger carries out body bending) being approximately perpendicular to main part 15 so that main part 15 vertical or substantially vertical with bending part 16 and 17 (referring to Fig. 6).
As it can be seen in figures 5 and 6, main part 15 is the trapezoidal heat exchange side in heat exchange module 100, the bending part 16 and 17 of heat exchanger 10 constitutes a rectangle heat exchange side of heat exchange module 100 respectively with two bending parts of another heat exchanger 20.It is understood, however, that aforementioned body portion 15 and bending part 16,17 are only a kind of examples for rectangular shape and trapezoidal shape, it can be selected to any suitable shape as required, for instance general square shape, trapezoidal, parallelogram shape.
In main part 15, a flat tube length bottom is the shortest, and flat tube length topmost is the longest, and the spacing between flat tube and flat tube is L.And preferably so that the length of the flat tube in bending part is incremented by successively with 2Ltg α from lower to upper.In order to easy to process, the length of every flat tube can slightly adjust.
In Forging Process, it is preferable that make flat tube the substantially trapezoidal shape side of bending angle α (i.e. main part 15) two waist edge between the half of angle of angle β, but as long as generally in the scope of β/2-5 ° to β/2+5 °.The angle of the angle β between bending axis Y and bending axis Y ' is preferably so as to be substantially equal to the vertex angle theta of the trapezoidal side of heat exchange.Certainly, above-mentioned wrap direction is only an example of the present invention, and certain those skilled in the art can select other mode (such as with another angle) to carry out bending as required.
In order to easy to assembly, the end of the flat tube 13 in header 11 or 12 side can be made by bending flat tube 13 vertically or generally perpendicularly insert in the groove of header 12.Certainly, those skilled in the art can also make the bending part position of bending axis Y and Y ' place (namely substantially) of flat tube 13 approximately or substantially not have fin, is so easier to heat exchanger 10 bending, and radius bend can also be made little as much as possible.
It will be appreciated by those skilled in the art that, in the present embodiment, owing to the right side heat exchanger 10 in heat exchange module 100 is roughly the same with left side heat exchanger 20 or symmetrical, therefore, the structure of heat exchanger 20 is roughly the same with the structure of heat exchanger 10 and principle with the principle of bending, does not repeat them here.
Refer again to Fig. 2 and 6, heat exchanger 10 and heat exchanger 20 to be connected with each other by header each other, to form heat exchange module 100.Namely, header in heat exchanger 10 is connected with the header in heat exchanger 20, another header in heat exchanger 10 is connected with another header in heat exchanger 20, the main part making heat exchanger 10 and heat exchanger 20 is used separately as two trapezoidal heat exchange sides of heat exchange module 100, which adds heat exchange area.Those skilled in the art can select concrete set-up mode as required, is not limited to above-mentioned mode.Listed above merely to exemplary explanation, it is impossible to be interpreted as a kind of restriction to the present invention.
Although illustrating various sizes of heat exchanger in figures 3-4, but its wrap direction is identical with the heat exchanger in Fig. 2, it is different in that, in heat exchanger in fig. 2, two bending parts is equivalently-sized, and two bending parts equivalently-sized of each heat exchanger 60,70 in figure 3, but the size of the bending part that two heat exchangers 60,70 are each other is different；The size of two bending parts of each heat exchanger is different in the diagram, but two heat exchangers are mutually symmetrical.In view of the heat exchanger formed described in Fig. 3-4, those skilled in the art can select the size of bending part according to actual needs, is obtained with according to the bending method described in Fig. 2, therefore is not described in detail in this.
Referring to Fig. 7 and 8, which particularly illustrate the structural representation before and after its bending of heat exchange in Fig. 4.
For Fig. 7, illustrate that the wrap direction of the heat exchanger 80 that both sides have bending part is: first carry out the bending of flat tube 83, then carry out the body bending of heat exchanger 80.Concrete bending step is as follows: first, by the both sides (in as shown the left and right sides of flat tube) of every flat tube 83, with the width (i.e. fore-and-aft direction in the page) of this flat tube for axis, flat tube is bent into angle [alpha], and the flat tube 83 after bending is sequentially inserted in the groove (not shown) of header.Then, by adjust flat tube position, make all flat tubes 83 either side bending part substantially on one wire, i.e. on bending axis Y and Y ' as shown in Figure 7.It should be noted that form described angle beta (but the distance of the header of two bending axial line distance both sides is different, causes the size difference of the bending part ultimately formed) between two bending axis Y and Y '.So, heat exchanger 10 is the formation of main part 85 and bending part 86,87.Between adjacent flat tube, insert fin 84, then put soldering oven soldering into integral.Finally, by the bending part 86 and 87 in the heat exchanger after bending with bending axis Y and Y ' for bending axis, along the direction bending (namely heat exchanger carries out body bending) being approximately perpendicular to main part 85 so that main part 85 vertical or substantially vertical with bending part 86,87 (referring to Fig. 8).
As shown in FIG. 7 and 8, main part 85 is the trapezoidal heat exchange side in heat exchange module 100, and the bending part 86 and 87 of heat exchanger 80 constitutes a rectangle heat exchange side of heat exchange module 100 respectively with two bending parts of another heat exchanger 80.It is understood, however, that aforementioned body portion 85 and bending part 86,87 are only a kind of examples for rectangular shape and trapezoidal shape, it can be selected to any suitable shape as required, for instance general square shape, trapezoidal, parallelogram shape.
In main part 85, a flat tube length bottom is the shortest, and flat tube length topmost is the longest, and the spacing between flat tube and flat tube is L.And preferably so that the length of the flat tube in bending part is incremented by successively with 2Ltg α from lower to upper.In order to easy to process, the length of every flat tube can slightly adjust.
In Forging Process, it is preferable that make flat tube the substantially trapezoidal shape side of bending angle α (i.e. main part 15) two waist edge between the half of angle of angle β, but as long as generally in the scope of β/2-5 ° to β/2+5 °.The angle of the angle β between bending axis Y and bending axis Y ' is preferably so as to be substantially equal to the vertex angle theta of the trapezoidal side of heat exchange.Certainly, above-mentioned wrap direction is only an example of the present invention, and certain those skilled in the art can select other mode (such as with another angle) to carry out bending as required.
In order to easy to assembly, the end of the flat tube 83 in header side can make flat tube 83 vertically or generally perpendicularly insert in the groove of header by bending.Certainly, those skilled in the art can also make the bending part position of bending axis Y and Y ' place (namely substantially) of flat tube 83 approximately or substantially not have fin, is so easier to heat exchanger 80 bending, and radius bend can also be made little as much as possible.
Foregoing illustrates above-mentioned different types of heat exchanger, but they have the advantage that
1) end vertical of flat tube inserts header, it is possible to the design of traditional manifold, it is not necessary to additional investment header mould, reduce Machining of Pick-up Tube difficulty.
2) can pass through to arrange baffle plate in the middle of two heat exchangers makes each heat exchanger fan be combined into a separate unit, so when low load operation, if a unit is out of service, it is possible to effectively prevent distinguished and admirable through unit out of service, thus improving heat exchange efficiency, reduce energy consumption.Structure when Fig. 9-11 couples is provided with baffle plate is described.
Figure 9 illustrates the structural representation when heat exchange module in Fig. 2 uses together with baffle plate 90.In view of the heat exchanger 10 and 20 in Fig. 2 is of the same size, therefore baffle plate 90 is arranged to be positioned at the straight baffle plate 90 between the header (four shown in figure circle is header, in this case be concisely only labelled with header 11) of heat exchanger 10 and 20.
Figure 10 illustrates the structural representation when heat exchange module in Fig. 3 uses together with baffle plate 90.In view of the bending part each other of the heat exchanger 60 and 70 in Fig. 3 is of different sizes, therefore baffle plate 90 is arranged to be positioned at the baffle plate 90 wriggled between the header (four shown in figure circle is header, in this case be concisely only labelled with header 71) of heat exchanger 10 and 20.
Figure 11 illustrates the structural representation when heat exchange module in Fig. 4 uses together with baffle plate 90.In view of two heat exchangers 80 in Fig. 4 are of the same size, but they are mutually symmetrical, therefore be arranged to baffle plate 90 to be positioned at, between the header (four shown in figure circle is header, in this case be concisely only labelled with header 11) of two heat exchangers 80, there is step-like baffle plate 90.
