It should be noted that according to the second embodiment variant of the present invention in this aspect of the present invention, heat exchange surface 5 is formed by first wall 4 that can be configured with deformation device 8 whole or in part.In other words, heat exchange surface 5 can comprise the first wall 4, or is made up of the first wall 4.
While second wall 7 and the first wall 4 are arranged each other with distance D, positioned opposite to each other especially.According to the various distortion considered, distance D and thickness E are equal to each other or different features.
According to another unshowned embodiment variant, the second wall 7 and the first wall 4 parallel.
According to the 3rd embodiment of the present invention shown in Fig. 7, heat exchanger 1 is made up of single pipe 2, this pipe is such as constructively cylindric, and comprise the first wall 4, it such as corresponds to the Part I contacted with external agency 6 of cylindrical tube 2 haply, and second wall 7, its such as correspond to haply cylindrical tube 2 haply in the face of the Part II of the first wall, it does not contact with described external agency 6.In this case, such as, two walls 4,7 are configured with deformation device 8.In other words, the circumference of pipe all or part of and its length may be configured with such deformation device 8, but only the first wall 4 forms heat exchange surface 5.
It will be understood that, pipe 2 can individually or in combination comprise make pipe 2 meet the preceding feature of the following condition of the present invention at least any one, included feature is at least provided with the device 8 be out of shape by the second wall 7 fact by pipe 2 forms, and makes pipe 2 and heat exchanger 1 can have different structure and arrange.
By first of support first embodiment the distortion especially as shown in Figure 5, open hereinafter, in Fig. 5 example, while the second wall 7 is configured with separately deformation device 8, the first wall 4 forms heat exchange surface 5 to advantage of the present invention.Also noteworthy is that, such advantage is alternatively suitable for for other modification of the present invention.
Also see Fig. 8, these structures, by the disturbance of the first limiting layer C1 contacted with the first wall 4 of fluid 3 and/or the disturbance of the second limiting layer C2 that contacts with the second wall 7, enhance the hot-fluid between fluid 3 and external agency 6
transmission.This is because the distortion disturbance of the second wall 7 flowing of fluid 3 in pipe 2, this disturbance promotes hot-fluid
transmission.The result produced is limiting layer, i.e. the instability of ground floor C1 and/or second layer C2, this finally promotes hot-fluid
transmission.In the illustrated embodiment, the distortion of the second wall 7 alternately destroys and the flowing of accelerating fluid 3 near the second wall 7.Heat exchanger 1 of the present invention is by the limiting layer contacted with the first wall 4 and/or the second wall 7 of fluid 3, the i.e. disturbance of the flowing of ground floor C1 and/or second layer C2 thus, creates the hot-fluid of the optimization between fluid 3 and external agency 6
transmission.Such disturbance make away from the first wall 4 the second limiting layer C2 can with the first limiting layer C1 contacting the first wall 4 in temperature evenly, which increase the total hot-fluid between external agency 6 and fluid 3
transmission.Finally, deformation device 8 stop limiting layer C1, C2 along the first wall 4 and the second wall 7 thickening, destroy these limiting layers C1, C2 until final.By by way of example, compared with the heat exchanger of prior art, the hot-fluid obtained by heat exchanger 1 of the present invention
the increase with 600% is observed in transmission especially.
These structures apply a spread speed by the deformation waves 9 of bearing at the second wall 7, also make it possible to the function being integrated with pumping fluid 3.Deformation device 8 can make the second wall 7 bear accurate and controlled deformation waves 9, makes fluid be attended by such distortion thus, and flows finally be in the effect of such deformation waves 9 in pipe 2 under.Deformation waves 9 such as being periodic in physical property, sine wave as shown in Figure 9, but the while that to be also preferably row ripple may being maybe standing wave, fixed or changed amplitude A can be had.Deformation waves 9 can also be such as superpose by these deformation waves the deformation waves generated.Such advantage is for including small size as being less than 1mm
2the heat exchanger 1 of section S useful especially.In this case, the strain amplitude A of the second wall 7 can be comparatively large, such as, be about 80% of the distance D between the first wall 4 and the second wall 7, or or even 90%, such amplitude up to almost 100% of distance D, thus obtains the rate of flow of fluid 3 of requirement.
These structures also make it possible to control pump function, it is, rely on physical property and the feature of the deformation waves 9 be applied on the second wall 7, the pumping of fluid 3 can be regulated at the every bit place of the second wall 7, thus the flow velocity of fluid 3 can be controlled on the vertical direction of the every bit of the second wall 7.
These structures also to make it possible to control in heat exchanger 1 and the time of staying of fluid 3 particularly between the first wall 4 and the second wall 7.When fluid 3 is made up of various ingredients, these configurations make the mixing that especially can improve these components.Furthermore, heat exchanger 1 also can be used in reactor interchanger field, for reactor interchanger, in order to constant hot-fluid
transmission, control for the time of staying of the fluid 3 in heat exchanger 1 advantageously can obtain from changes in flow rate, and can obtain more accurately in special embodiment of the present invention, this embodiment will illustrate after a while in figure 16, in this embodiment, the conveying that fluid 3 follows the shell with spiral helicine path in the deformation wave train 9 makes it can form the different time of staying as requested, and this can obtain many advantages, particularly at chemical field.
Finally, these structures make it possible to the performance controlling heat exchanger 1 independent of rate of flow of fluid 3 ground.This is because the performance of heat exchanger 1, as hot-fluid
transmission coefficient and rate of flow of fluid 3 are functions of the wave number of the parameter of deformation waves 9 and the deformation waves of amplitude A, frequency, wavelength X and description sine.Therefore, in order to the performance of the requirement of heat exchanger 1, the adjustment of these parameters makes it possible to obtain the fluid flow rate 3 required.These structures are arranged like this, can for constant when to make by the thermal power of the exchange of the first wall 4 at flow velocity and/or in the input temp change of fluid 3 in pipe 2.The result finally produced affects hot-fluid for being formed
the ability of transmission, this hot-fluid
the fluid source 3 transmitted relative to having a variable-flow characteristic is constant.Finally, this result produced is formed to make flow velocity in pipe 2 or hot-fluid
the ability of change, this ability makes it possible to adjust constant heat flux relative to variation flow rate or adjust variable heat flux relative to constant flow rate.
The result that these structures and advantage produce is the particularly advantageous application of a kind of the present invention, for heat exchanger 1 being integrated in the microsystem of microfluid type as in microreactor or similar device.Heat exchanger 1 of the present invention provides the possibility of the increasing avoiding surface size and the overall dimensions reducing heat exchanger 1.This is because heat exchanger 1 of the present invention is advantageously compact setting, its size is by means of the better hot-fluid of the first wall 4
transmit and reduced by entirety, and this better hot-fluid
transmission is because the deformability of the second wall 7 produces.
This result produced is, according to the special embodiment of the present invention, such heat exchanger 1 can discharge the considerable hot-fluid from external agency 6
.Thus, this external agency can comprise a large amount of electronic component, by heat dissipation electronic component produced by fluid 3, and will advantageously fast and effectively cooling electronic components.Such discharge realizes further by subtracting undersized first wall 4.
This result produced is also the modularity that heat exchanger 1 of the present invention improves, and it is, the hot-fluid that such heat exchanger 1 realizes
transmission is independent of rate of flow of fluid 3, and thus, when rate of flow of fluid 3 is implemented for special application, the heat of any relative magnitude can both be discharged by heat exchanger 1 of the present invention.Such structure makes it possible to avoid usually forming the brute force of prior art heat-exchanging loop parts and the use of the pump of heaviness.
These structures are arranged like this, make heat-exchanging loop 10 of the present invention simple as much as possible.Such heat-exchanging loop 10 such as first and foremost comprises heat exchanger 1 and heat exchanger 11, and heat exchanger 11 on the contrary operating fluid 3 carries out heat exchange, this heat exchange with carry out in heat exchanger 1 contrary.Heat exchanger 11 selectively has the feature identical with those features in order to describe heat exchanger 1.In other words, the hot-fluid implemented in heat exchanger 1
be transmitted as external agency 6 when transmitting the heat transfer of heat to fluid 3, the heat transfer so in heat exchanger 11 is the heat transfer of fluid 3 externally environment 12 release heat.On the contrary, the hot-fluid implemented in heat exchanger 1
when being transmitted as the heat transfer that external agency 6 catches from the heat of fluid 3, the heat transfer so in heat exchanger 11 is the heat transfer that fluid 3 catches the heat from external environment condition 12.In the application of each Heat transmission front mentioned only by the described deformation device 8 of heat exchanger 1 of the present invention, fluid 3 is utilized to implement in the circulation of loop direction 13 in heat-exchanging loop 10.In other words, heat-exchanging loop 10 of the present invention does not comprise the mechanical device of pump or other circulation of fluid 3 in heat-exchanging loop 10, and such function provided by the heat exchanger 1 being advantageously integrated with pumping fluid 3 function.According to a further aspect in the invention, heat exchanger 1 makes it possible to reduce the power of the complementary pump be arranged on heat-exchanging loop 10.
Fluid 3 caused by deformation waves 9 in the flowing of heat-exchanging loop 10, and this deformation waves 9 is by the mode drive fluid 3 of viscous force and pressure.In heat exchanger 11, the integrated direct result of pump function is the compactedness increasing heat-exchanging loop 10.The omission of the pump on heat-exchanging loop 10 avoids prior art to comprise all faults intrinsic in the heat-exchanging loop of such pump and maintenance operation further.
Figure 11 shows for various deformation waves frequency 9 between 1Hz and 50Hz and for equaling the distance D of 1mm and equaling the wave number of 10, as the heat transfer coefficient gain G of the function of relative amplitude A/D.To be observed, heat transfer coefficient gain G is the function of relative amplitude A/D and deformation waves 9 frequency f simultaneously.Thus under the maximum and tens hertz frequencies of relative amplitude A/D, can obtain up to 600% Heat transmission intensity gain.Under the large relative amplitude of deformation, obtain this fact of maximum gain mean that this method is suitable for the system be made up of small distance D passage.This is because in this case, little amplitude A can produce large relative amplitude A/D.
Figure 12 shows the mass flow H of the function as relative amplitude A/D for deformation waves frequencies 9 different between 1Hz and 50Hz.Except the integrated of pump in heat exchanger 1 improves except this fact of compactedness of heat-exchanging loop 10, will observe, with under the identical experiment condition described before those, mass flow H is from 1kg/m
2﹒ s is changed to 260kg/m
2﹒ s.Under maximal phase is to amplitude A/D, obtain best pump-conveying property, this makes heat-exchanging loop 10 of the present invention be applicable to have the pipe 2 of small distance D especially.
Result for the pipe 2 with 1mm distance D graphically illustrates in fig. 13, in this chart, all be positioned at the point of Figure 13 shadow region Z can be obtained.Thus, if such as method requires the heat transfer coefficient of four times for prior art heat transfer coefficient of heat exchanger, be also the gain G of 300%, be so positioned at 0kg/m
2﹒ s and 230kg/m
2all mass flow H between ﹒ s can be used, and without the need to adjusting hot-fluid
intensity.In the Z of shadow region, heat transfer coefficient thus with the value decoupling zero of the mass flow H of fluid 3.This characteristic is useful especially in thermal process control.The knowledge of the relation between the amplitude A of the coefficient of heat transfer (and respective mass flow H) and deformation waves 9 and frequency makes it possible to easily as requested, uses Deformation control by the temperature of the first wall 4 or the simple measurement of the temperature of fluid 3 of discharging from heat exchanger 1.
In Figure 14 and 15, by using deformation device 8 to obtain these results, deformation device 8 comprises at least one actuator 14, and it can be electromagnetism, pneumatic, hydraulic pressure, piezoelectricity or similar fashion.Be applicable to implement in deformable piezoelectric actuator 14 of the present invention, the actuator without the need to amplification with direct linear deformation can be set up, as solid and the actuator of multi-layer ceramics type, external lever effect, as " hoodle " actuator of level type, or there is " bending " actuator of internal lever effect, as prestressing force " bends " actuator or bimorph actuators.
For micro heat exchanger 1, the actuator 14 preferably there is former dynamic action type, distributing along the second wall 7.For the heat exchanger 1 of large-size, use the multiple actuators 14 distributed along the second wall 7, such actuator 14 is the former dynamic action type in local, and is configured with independently parameter controller, to produce multiple deformation waves 9.In the mode of nonlimiting examples, heat exchanger 1 of the present invention have developed a kind of active principle based on utilizing laminated piezoelectric pottery.Due to require the variable and approximately process of 1mm, need to use the device amplifying the motion obtained by actuator 14, such device is such as cantilever beam and/or flexure beam type.In this case, the larger power of actuator 14 generation is in order to make the lever motion of motion amplification.Multiple lever can be arranged in series.Preferably, the lever with flexible structure is selected to avoid friction and play.According to the embodiment of various deformation, actuator 14 is thrust actuator, or thrust and pulling force actuator.
