And, from the exit face of heat exchangerOne side to the thermograde of another side may hinder by the primary fluid stream of leaving heat exchanger be divided into have essentially identicalTwo or more shunting body streams of temperature.
Summary of the invention
The object of the present invention is to provide a kind of homogenization installation, this homogenization installation allows the fluid stream that leaves heat exchanger to existQuick and the reliable homogenizing of Temperature Distribution of another side is arrived on one side of the exit face of heat exchanger, and does not cause in fluid streamThe too much pressure loss. Further, the object of the present invention is to provide a kind of heat that comprises such homogenization installationInterchanger assembly. Finally, the object of the present invention is to provide a kind of method, the method equipment allows to leave heat exchangerFluid stream on one side of the exit face of heat exchanger to the quick and reliable homogenizing of Temperature Distribution of another side, and do not drawPlay the too much pressure loss in fluid stream.
These objects by have following feature homogenization installation, there is the heat exchanger assemblies of following feature and haveThe method of the Temperature Distribution in the homogenizing fluid stream of following feature and realizing.
Homogenization installation according to the present invention comprises the main body with flow channel, and flow channel extends through main body. This is mainStyle be as formed by the collector of heat exchanger at least in part, is particularly arranged in the exit region of heat exchangerHeat exchanger header. But, alternatively, this main body at least in part also can by heat exchanger outlet downstream extendPipe forms. But, also can expect, this main body comprises the Part I that formed by the collector of heat exchanger and by handing in heatThe Part II that the pipe that extend in the downstream of parallel operation forms.
Homogenization installation further comprises the flow control apparatus being arranged in fluid flowing passage. This flow control apparatus quiltBe configured in the skin of fluid stream that flows through fluid flowing passage, bring out vortex, the stream of the internal layer of fluid stream simultaneouslyDynamic characteristic keeps not being subject to the impact of flow control apparatus substantially. Flow control apparatus may not be constructed to not affect completely streamThe flow behavior of body stream internal layer. Alternatively, certainly can expect, for example, work as the downstream of fluid circulation via flow control appliance, flow control apparatus affects fluid stream internal layer when in the region. But, in homogenization installation according to the present invention, the control of flowingControl equipment is constructed to bring out vortex in the skin of fluid stream, simultaneously at least for a certain period and/or at least along fluidThe a certain length of flow channel, the impact that the flow behavior of fluid stream internal layer keeps not being subject to flow control apparatus.
In homogenization installation according to the present invention, the skin of flow control apparatus inducing fluid stream is with respect in fluid streamRotatablely moving of layer. Therefore, flow control apparatus is for the one side that is presented at the cross section of fluid stream in homogenizing fluid streamArrive the temperature of the thermograde (, edge is basically perpendicular to the thermograde of the direction of the flow direction of fluid stream) of another sideDegree distributes effective especially, because show in fluid stream that the skin that flow by fluid in the region of maximum temperature difference flows with respect to fluidRotatablely moving of internal layer and close contact each other. Compared with the temperature difference existing in the skin flowing with fluid, the internal layer of fluidIn the temperature difference relatively little. Therefore, at least for a certain period and/or at least along a certain length of fluid flowing passage,The fact that flow control apparatus does not affect the flow behavior of fluid stream internal layer substantially can not weaken flow control apparatus substantiallyHomo-effect. Alternatively, the structure of flow control apparatus is guaranteed the pressure loss quilt of the fluid stream being caused by homogenization installationRestriction.
Therefore, allow to show along the flow direction that is basically perpendicular to fluid stream in fluid stream according to homogenization installation of the present inventionThe quick and reliable homogenizing of Temperature Distribution of thermograde of direction, and be therefore particularly suitable for homogenizing and leave heat exchangeThe fluid stream of device. Meanwhile, the pressure loss in the fluid stream being caused by homogenization installation is low especially. When according to of the present inventionHomogenization installation is used to homogenizing while leaving the Temperature Distribution of fluid stream of heat exchanger, can improve the downstream of heat exchangerAccuracy and the reliability of the measurement of inductance of the temperature of fluid stream. Further, should at the fluid stream in the downstream of heat exchangerWhen this is divided into two or more shunting body streams, homogenization installation guarantees that shunting body stream has essentially identical temperature.
Flow control apparatus is preferably arranged in the region of inwall of fluid flowing passage. For example, flow control apparatus canBe attached to the inwall of fluid flowing passage or form with the inwall entirety of fluid flowing passage. Further, flow and controlEquipment is preferably the static device that does not comprise displaceable element. Static flow control apparatus does not need for driving the control of flowingThe existence of the extra power of control equipment. Alternatively, flow control apparatus permission impact flows through fluid flowing passageThe flow behavior of fluid stream, for example, with the Temperature Distribution in homogenizing fluid stream, wherein affects the flow behavior of fluid streamFluid stream itself is taken from required energy input, causes the pressure drop in fluid stream. But, as discussed above,According in homogenization installation of the present invention, due to the structure of flow control apparatus, in the fluid stream being caused by homogenization installationThe pressure loss is limited.
According in the preferred embodiment of homogenization installation of the present invention, flow control apparatus be constructed to make fluid stream outsideLayer is advanced along the spirality fluid flow path of the inwall along fluid flowing passage. By forcing the skin edge of fluid streamSpirality fluid flow path and advance, can affect the homogenizing of Temperature Distribution in fluid stream fluid flow path effectivelyLength is increased. Therefore, the homo-effect of homogenization installation is enhanced, and does not need to increase the required installation of homogenization installationSpace.
Flow control apparatus can further be constructed to bring out in the cushion between skin and the internal layer of fluid stream relevantEddy current. For example, the structure of flow control apparatus can flow in the impregnable situation of flow behavior of internal layer at stream at fluidAfter bringing out period of vortex in the skin of body stream or unaffected in the flow behavior of fluid stream internal layer at fluid streamSituation under bring out the length of fluid flowing passage on vortex institute edge in the skin that flows by fluid after, impel at fluidIn cushion between skin and the internal layer of stream, produce relevant eddy current.
For example, the relevant eddy current in the cushion between skin and the internal layer of fluid stream can lure by flow control apparatusSend out, this flow control apparatus is constructed to cause pressure reduction in fluid stream, the special downstream area at flow control apparatusCause pressure reduction. But, when flow control apparatus make flow stream skin advance along spirality fluid flow path and inLayer is still when substantially the fluid flow path along the longitudinal axis of fluid flowing passage is advanced, or when fluid streamThe angular speed of the vortex bringing out in skin be greater than internal layer the angular speed rotatablely moving (this can be for example flow control establishSituation in standby downstream area) time, also can in the cushion between skin and the internal layer of fluid stream, bring out relevant whirlpoolStream. In this case, in the cushion of the relative motion between internal layer and skin between skin and internal layer, bring out separatelyOuter vortex, and therefore in the cushion between skin and the internal layer of fluid stream, produce relevant eddy current.

Detailed description of the invention
Fig. 1 illustrates the Temperature Distribution in the fluid stream that leaves installation heat exchanger aboard. Become by Fig. 1Be apparent that, fluid stream is presented at one side of exit face of heat exchanger to the thermograde of another side, wherein works asFluid stream leaves the collector with the first flow cross section of heat exchanger and enters in the downstream of heat exchanger and extendsAnd while thering is the pipe of second flow cross section less than the first flow cross section of heat exchanger header, substantially maintainThis thermograde. In fluid stream, cold flow is mainly present in the lower part of heat exchanger header and in heat exchangeIn the lower part of the pipe that extend in device downstream. In contrast, warm current is mainly present in heat exchanger header and hands in heatIn the upper part of the pipe that extend in parallel operation downstream. The central area of fluid stream shows medium temperature. Therefore, leave heatThe fluid stream of interchanger is presented at one side of its cross section to the thermograde of another side, along being basically perpendicular to streamThe thermograde of the direction of the flow direction F of body stream.
Leave the Temperature Distribution of the fluid stream of heat exchanger for homogenizing, can adopt the homogenization installation of describing in Fig. 210. Homogenization installation 10 comprises the main body 12 with fluid flowing passage 14, and fluid flowing passage 14 extends throughMain body 12. Main body 12 comprises the collector 16 of heat exchanger, is particularly arranged in the collection in the exit of heat exchangerPipe 16. Main body 12 further comprises the pipe 18 that has circular cross section and extend in heat exchanger header 16 downstreams.With similar in Fig. 1, the flow direction that leaves heat exchanger and flow through the fluid stream of fluid flowing passage 14 existsIn Fig. 2, also indicated by arrow F.
The collector 16 of heat exchanger has than the large flow cross section of flow cross section of pipe 18. Therefore, extendComprise by collector 16 and limit and there is first of the first flow cross section by the fluid flowing passage 14 of main body 12Part 14a. Further, fluid flowing passage 14 comprises by the pipe 18 extending in heat exchanger header 16 downstreamsLimit and have than the first flow cross section of the Part I 14a of fluid flowing passage 14 little second flow horizontalThe Part II 14b in cross section.
Homogenization installation 10 further comprises the mobile control in the region of the inwall 22 that is arranged on fluid flowing passage 14Control equipment 20. According in the embodiment of the homogenization installation 10 of Fig. 2, flow control apparatus 20 comprises from fluidFour control blades 24 that flow that the inwall 22 of flow channel 14 extends. Flowing, it is mobile along fluid to control blade 24The circumferential distribution of passage 14 also tilts with respect to the inwall 22 of fluid flowing passage 14, thereby controls leaf by flowingThe first first type surface 26 and the angle [alpha] that the inwall 22 of fluid flowing passage 14 limits of sheet 24 are less than 90 °, andAnd control restriction between the second first type surface 28 and the inwall 22 of fluid flowing passage 14 of blade 24 flowingAngle beta is greater than 90 °. Further, the mobile blade 24 of controlling is designed so that its first first type surface 26 is carriedFor having convex curvature, and its second first type surface 28 is provided and has concave curvature.
Mobile the first upstream portion of controlling blade 24 is arranged in the Part I 14a of fluid flowing passage 14,, extend from the inwall of collector 16. Mobile the second downstream part of controlling blade 24 is disposed in fluid and flowsIn the Part II 14b of passage 14, that is, extend from managing 18 inwall. But the control blade 24 that flows existsThe flow direction F that fluid stream flows through fluid flowing passage 14 controls the whole extensions of blade 24 along flowingInward flange region 30 be arranged to the central axis A of fluid flowing passage 14 at a distance of preset distance.
In Fig. 3, describe flow control apparatus 20 flows by the mobile spy of the fluid stream of fluid flowing passage 14The impact of property. First, the mobile control blade 24 of flow control apparatus 20 is flowing through fluid flowing passageIn the skin 32 of 14 fluid stream, bring out vortex S, that is, the skin 24 of fluid stream is with respect to the internal layer of fluid stream34 rotatablely move, referring to Fig. 3 a. Due to rotatablely moving of the skin 32 of fluid stream, in fluid stream, haveThe region of high-temperature contacts with the region in fluid stream with lower temperature. As a result, as the fluid of describing in Fig. 1One side of the cross section of stream to the Temperature Distribution of another side by homogenizing significantly. In the control blade 24 that flowsFringe region 30 is arranged to the central axis A of fluid flowing passage 14 at a distance of preset distance, so fluidThe internal layer 34 of stream keeps not substantially being subject to flow control apparatus 20 in the time of the upstream portion by flow control apparatus 20Impact. Therefore, the internal layer 34 in the upstream region of flow control apparatus 20 has the stream of being basically parallel to conventionallyThe flow direction of the central axis A of body flow channel 14. Under any circumstance, in the skin 32 of fluid stream, lureThe angular speed of the vortex S sending out is greater than the angular speed rotatablely moving of internal layer 34, for example, and the rotation fortune of internal layer 34Move in the time that fluid stream reaches the downstream area of flow control apparatus 20 and may produce. As a result, make to control and establish by flowingMinimise loss of pressure in the fluid stream that standby 20 homogenization causes.
Control shape and the layout of blade 24 owing to flowing, make to flow through the fluid stream of fluid passage 24Outer 32 advance along the spirality fluid flow path of the inwall 22 along fluid flowing passage 24. Be parallel toThe fluid flow path that the central axis A of fluid flowing passage 14 is extended is compared, along fluid flowing passage 14The spirality fluid flow path of inwall 22 is obviously longer, and does not need homogenization installation 10 to have larger sizeAnd therefore do not need larger installing space. But the homogenizing of Temperature Distribution can be along spirality fluid in fluid streamWhole length of flow path occur, thereby can realize the homogenizing very effectively of the Temperature Distribution in fluid stream.
Due to the relative motion between skin 32 and the internal layer 34 of fluid stream and due to flow control apparatus 20The pressure differential existing in downstream area, between the skin and internal layer of the fluid stream in the downstream of flow control apparatus 20Cushion I in bring out relevant eddy current, referring to Fig. 3 b. Therefore, at the downstream of flow control apparatus 20, fluidThe internal layer 34 of stream also comprises turbulence characteristic, and it further improves the homo-effect of homogenization installation 10.
Fig. 4 and Fig. 5 illustrate the second embodiment of homogenization installation 10. According to the homogenization installation 10 of Fig. 4 and Fig. 5From be according to the different of the layout of Fig. 2: flow control apparatus 10 no longer comprises from fluid flowing passage 14The mobile control blade 24 that inwall 22 extends, but comprise in the inwall 22 that is formed on fluid flowing passage 14The first spiral slot 36 and the second spiral slot 38. The upstream extremity of the first groove 36 is arranged on fluid flowing passage 14Lower area in, that is, in fluid flowing passage 14, have in the region that the fluid of lower temperature flows through.By contrast, the upstream extremity that is formed on the second groove 38 in the inwall 22 of fluid flowing passage 14 is disposed in streamIn the upper area of body flow channel 14, that is, in fluid flowing passage 14, there is the fluid stream of higher temperatureIn the moving region of passing through.
Similar with the mobile control blade 24 according to the flow control apparatus 20 in the homogenization installation 10 of Fig. 2, shapeBecome the groove 36 and 38 in the inwall 22 of fluid flowing passage 14 first flowing through fluid flowing passage 14The skin 32 of fluid stream in bring out vortex S, and in the time passing through the upstream portion of flow control apparatus 20, fluidThe basic maintenance of internal layer 34 of stream is not subject to the impact of flow control apparatus 20, referring to Fig. 6 a. Because skin 32 is relativeIn rotatablely moving of internal layer 34, the fluid with lower temperature contacts with the fluid-tight with higher temperature, leadsCause the homogenizing of the Temperature Distribution in the fluid stream that flows through fluid flowing passage 14. Meanwhile, make to control by flowingMinimise loss of pressure in the fluid stream that equipment 20 causes.
Internal layer 34 in the upstream region of flow control apparatus 20 has the fluid flowing passage of being basically parallel to conventionallyThe flow direction of 14 central axis A. Under any circumstance, the vortex S bringing out in the skin 32 of fluid streamAngular speed be greater than the angular speed rotatablely moving of internal layer 34, for example, rotatablely moving of internal layer 34 flowed at fluidWhile reaching the downstream area of flow control apparatus 20, may produce. Therefore, fluid stream is logical along flowing along fluidThe skin 32 that the spirality fluid flow path of the inwall 22 in road 14 is advanced is as a kind of " rolling for internal layer 34Axis of a cylinder holds (rollerbearing) ", cause the streamline (fluidstrand) being limited by groove 36,38 around streamlineThe rotatablely moving of central axis, wherein this of streamline rotatablely moves and even also can maintain in the downstream of groove 36,38.At the downstream area of flow control apparatus 20, the relative motion between skin 32 and the internal layer 34 of fluid stream is at streamIn cushion I between skin 32 and the internal layer 32 of body stream, bring out relevant eddy current, referring to Fig. 6 b. Therefore, existIn the downstream area of flow control apparatus 20, the internal layer 34 of fluid stream also comprises by flow control apparatus 20 and brings outTurbulence characteristic. As a result, can further strengthen the homo-effect of homogenization installation 10.
