Description

Dynamic inertia driven heat exchanger

The present invention relates to a kind ofly have the fluid pumping and nationality inertia drives heat in the fluid thermal exchange process a kind of efficient heat exchanger of transmission, belong to technical field of heat exchange.

Heat exchanger is to separate fluid by one to make mutual impervious wall heat is sent to the well-known equipment of another fluid from a kind of fluid.Here, this term of fluid is meant any non-solid, can be the combination material, comprises gas, steam and liquid.Usually heat passes to wall by removing with the lower opposite side fluid of the contacted temperature in wall surface from the higher fluid of wall one side temperature.It is necessary that the partition wall both sides exist the temperature difference to pass to another fluid from a kind of fluid for heat.Heat passes to wall inner necessary cross over one and the contacted boundary layer of wall from fluid, and this boundary layer is zero with respect to wall at its rate of flow of fluid of the place of being close to the wall surface.The transmission of heat must be crossed two this boundary layers concerning liquid-liquid class heat exchanger.The boundary layer has stopped hot transmission, because in the boundary layer be laminar flow and non-turbulent flow, do not have continuous liquid to exchange this on the direction perpendicular to heat exchanger wall under the laminar flow situation conduction of heat is restricted.Heat exchanger inner boundary layer scope causes the immixture of fluid that heat transfer rate is improved greatly with outer fluid owing to turbulent flow.Reducing boundary layer thickness in traditional heat exchanger, to make fluid carry out heat exchange better be by specially creating turbulent flow near the way that liquid mixes the wall to be realized, this requires the expenditure of energy, the loss of energy is that the viscous force vector is antiparallel to the velocity vector of fluid to a point because the bulk shear takes place in rheid.The magnitude of power consumption is proportional to the speed of corresponding fluids and the integrated value of product in whole heat exchanger volume of viscous force.Is favourable with the thickness that reduces the boundary layer to heat exchange creating turbulent flow near the place of exchange wall, but making turbulent flow then is undesirable away from the boundary layer infiltration and development in the bulk fluid, it has hindered the directed transport of fluid in the whole system, brings noise and causes mechanical loss of energy.The heat exchange coefficient on any surface and the boundary layer thickness relation of being inversely proportional to, boundary layer thickness is defined as the vertical range that begins to take place turbulent flow from wall to fluid, the character that depends on used fluid provides a velocity gradient with respect to wall in the boundary layer, when this place's speed surpasses then turbulent flow generation of critical value.

Usually the exchange wall of fluid pill utilizes some additives, corrugated material, and fin or other configurations make the local easily turbulization of abuts wall and increase contact-making surface.In a word, its design objective is to utilize various ways to create turbulent flow to reduce boundary layer thickness and increase the exchange wall surface area that contacts with fluid in conventional heat exchanger.

Design philosophy of the present invention and traditional heat exchanger have a great difference.The invention provides a kind of method that can strengthen the fluid mixing, produce a kind of inertia force F that acts locally on the boundary layer artificially, this inertia force F and heat pass that exchanger wall enters fluid and the fluid temperature gradient that causes is relevant, thereby also relevant with the fluid density gradient that forms therefrom.We know that fluid exists thermograde in the boundary layer, this be because laminar flow make material can not mix cause, less this of thermograde is because the result that turbulent flow is mixed in the fluid far away of boundary layer.Obviously, concerning a side of obtaining heat, be close to the high density minimum of that layer fluid temperature on wall surface.If it is heat exchange surface and fluid are placed an acceleration referential of pivoting then will produce inertial force field, illustrated in figures 1 and 2 as principle.This differential power dF acts on arbitrary small volume units d in the heat exchanger

, should be relevant with this speed of density, fluid of locating fluid:

dF/d

＝d（ρ（T） (dV)/(dt) ）/d

Wherein ρ (T) is that the fluid density of present position is relevant with temperature T; V is a fluid velocity; T is the time.

Inertia force F role is to drive that part of fluid motion less with respect to surrounding fluid temperature higher density, and the direction of its direction of motion and applied force is opposite, thereby has caused the relative motion of fluid in the boundary layer.Inertial force field impels in the zone of those thermograde maximums fluid to mix and strengthens, and the main variations in temperature district in the heat exchanger just in the boundary layer.The inertia force relevant with thermograde causes the inner relative motion of fluid will be because of boundary layer internal viscosity loss consumed energy, but viscous loss also goes to zero because of its thermograde goes to zero then for most of fluid of flowing beyond those boundary layer scopes; On the other hand, the velocity vector V of fluid in the heat exchanger as shown in Figure 1, can be decomposed into three components, i.e. angular velocity vector V(θ), axial velocity vector V(Z) and radial velocity vector V(r).In fact, in the present invention the numerical value magnitude of these three velocity components generally has | V(θ) |＞| V(Z) |＞| V(r) |.Angular velocity vector V(θ) and axial velocity vector V(Z) each other perpendicular to the F force vector, so the dot-product of power F and these two components is zero.The power F of this means can strengthen arbitrarily and not cause additional viscous merit loss because of the transport velocity of bulk fluid increases.The fluid of the different densities that inertia force F will be everywhere causes because of the heterogeneity of heat accelerates to radial velocity V(r), generally less relatively, so V(r because of its value) and F only form limited dot-product.Therefore, cause that by power F main energy consumption is confined to the Boundary-Layer Zone near wall.The direction of inertia force can be chosen wantonly and the present invention selects the direction of inertia force and bulk fluid velocity vector becomes the orthogonal directions of the best, thereby makes between them dot-product least energy utilization ratio the highest.

Principle that the present invention is used and the process in the conventional heat exchanger have significant difference.When utilizing fluid to go to reduce boundary layer thickness with turbulization with respect to the interchanger motion, viscous force will also go to zero because of fluid goes to zero to flow in the conventional heat exchanger, but the then corresponding increase of boundary layer thickness this moment.It only is because the convection current that gravity causes that the small fluid of in the boundary layer some mixes, even and the present invention under interchanger inner fluid zero mobility status, added inertia force still can not be subjected to destroy damply the boundary layer.In other words, the effect of inertia force always constantly destroys the variable density in the fluid, greatly reduces the thickness in boundary layer.The free convection that this effect of conventional heat exchanger can only lean on centrifugal force to produce, the present invention strengthens this effect greatly with artificial introducing inertia force.

According to the present invention, heat is separated by common wall interface 1 adjacent, have and exchange between two fluid streams that flowing in the passage 5 and 4 of any cross section, channel parallel is in rotating shaft and form firm structure, and it entirely rotates around common axis, sees schematic diagram 2.Second characteristic of design philosophy of the present invention are that fluid transport pump and heat exchanger organically are combined into an integral body, are two independently parts unlike pump and heat exchanger in the traditional hot switching architecture.According to the present invention, to the special occasions that has heat exchanger to pivot, can introduce an overall antisymmetry geometric configuration radially by the entrance and exit place of hot switching path, this configuration has the antisymmetry face to the interchanger both sides, can make fluid produce the twitch effect.These how much antisymmetry configurations are to arrange like this, and promptly fluid leaves heat exchanger framework place has bigger axle radius of turn and enter the framework place and be designed to have less axle radius of turn, shown in Figure 3 as principle.When hot switching path pivots, access port is also different because of radius of turn difference linear velocity, must produce pressure differential at two ends and cause the directed transport of fluid, it transports geometric configuration that direction only depends on that access port is arranged and the orientation independent that pivots with interchanger.The present invention around this principle can be arranged to the fluid transport direction in adjacent two hot switching paths identical or opposite at an easy rate.When fluid is endowed angular momentum during admission passage by the less mouth of axle radius, the angular momentum of fluid is conservation when it during by heat exchanger, therefore, the rotating shaft length of heat exchanger and related therewith system heat exchanger effectiveness can infinitely increase and not influence angular momentum.

The combination of pump and heat exchanger has brought another advantage.The traditional hot exchange system because of pump and interchanger separately, this part that two unit are connected must be brought noise because of the pumping turbulization of fluid.Obviously, there is not this shortcoming in native system, thereby has increased the mechanical efficiency that the heat-exchange system liquid transmits, and the noise that is caused by turbulent flow has reduced, and power consumption is also corresponding have been reduced.

Most of heat exchange surface is positioned on the direction of inertia force among the present invention, and any external suspended particles or the foreign substance different with fluid density all will be subjected to the effect of radial load and be swept from heat exchange surface, reduce the possibility of particle blocking channel.For gas-gas system, exotic is disposed the surface of productive set around outlet in the time of can keeping in repair in the cycle.Also be that the present invention has the automatically cleaning process, when the direction of heat exchange surface and power F was not parallel, this automatically cleaning process occurred over just and the opposite one side in power F aspect.

In the present invention, the heat exchange series of rotation is unified, and use rotatory sealing is necessary between any external fixed-piping, and especially working as fluid is the occasion of liquid.Because rotation envelope its diameter when spindle speed is determined has certain restriction, for prolonging its service life, the bore that can reduce the heat exchanger fluid outlet is deacclimatized the diameter that rotates envelope.Back-pressure will improve on the fluid flow direction when fluid flows to from bigger radius of turn when small-bore, be the angular momentum loss that prevents from therefore may cause, after fluid is by the rotation envelope, fluid can be transferred to heavy caliber once more, certainly angular speed will descend thereupon this moment, thereby to manage to make fluid angular speed to improve again be necessary.

The same with traditional heat exchanger, the volume heat transfer coefficient can apply increase exchange surface Method for Area such as ripple or fin to heat exchange surface and improve in the volume range that interchanger is determined.The further raising of overall thermal switching performance can also be by increase forming heat exchange surface passage length and utilize and arrange multiplexer channel and increase method such as heat exchanger radius of turn to realize.Also have, for increasing the insulation surfaces area of passage between two fluid streams, passage can be curled up axle by certain angle, at this moment these passages form a spiral.By this method, as long as technical permission can increase arbitrarily, natural is that this helix tube its cross section when passage length increases reduces to passage length under the situation that does not increase heat-exchange system axial length.

Another characteristic of the present invention be inertia force F will be in the whole volume of heat exchanger along with the opposite direction of the direction of flow inertia force vector of higher temperature and cause thermal shunt or thermally stratified layer.Especially principle schematic 4 is seen in the easier generation of this situation when importing and exporting the temperature difference great disparity of fluid.The internal procedure of this thermal shunt is important, divide the mixing between the fluid because it can cause exchanger fluid to import and export the location or have the mixing between the fluid layer of the remarkable temperature difference to reduce, so-called thermal shunt phenomenon that Here it is, obviously unfavorable to improving heat exchanger effectiveness.For making this thermal shunt phenomenon minimization, can isolation barrier be set at the place, gateway of fluid to separate the different fluid layer.For example cold fluid obtains the transmission heat after entering the interchange channel among Fig. 4 from the higher fluid of adjacency channel temperature, layering will take place under the effect of inertia strength, near rotating shaft place is the hot-fluid layer, away from the axle place is the cold flow layer, and the isolation barrier at figure middle outlet place will play cold fluid overflowed and be obstructed and hot fluid flows out unobstructed.The material of used isolation barrier should be thin and bad heat conducting.Equally, also similar isolation barrier can be set in the hot fluid porch of adjacency channel, purpose is that the thermal shunt phenomenon that reduces under the inertia force effect improves the efficient of heat exchange.

In heat exchanger, separately the passage of two bursts of different fluid structurally should be simple, and easy to clean, mechanical strength is firm etc.In principle, two kinds of structure types are arranged.First kind is that a fluid streams then flows in the outer tube of pipe in parcel by mobile another strand of the interior pipe of arbitrary section; Second kind is to transport the secondary air body and the cross section has common wall to separate arbitrarily between the passage, these passages alternately or alternately arrange the main body core that forms heat exchanger around axle by certain angle.These two kinds of principle methods will be described with various embodiment below.

The invention provides four class embodiment:

1. the air-air unit is used to the ventilation with recuperation of heat, and two fluid streams adverse currents are carried, and pump and heat exchanger form an organic whole.See that Fig. 2-1 is to Fig. 2-7.

2. with 1 said air-air unit, but have internal measure or structure, can reverse the direction that transports of one air stream wherein, can be used for simple ventilation.See that Fig. 3-1 is to Fig. 3-3.

3. a liquid is to the unit of air, and pump and interchanger are organic wholes, can be applicable to occasion such as cooling or air-conditioning automatically.See that Fig. 4-1 is to Fig. 4-4

4. a liquid is to the heat exchange unit of liquid.See Fig. 5.

Fig. 2-1 has showed the axial section of a gas to the gas heat-exchange system.This gas-gas heat-exchange system is installed in external rotor electric machine 15 epitrochanterian heat exchange cores by paired passage of arranging around rotating shaft 4,5 and gas discrepancy end member 6,7,8,9 compositions; Be fixed on the shell 10 on the stator, blast pipe 11 and the garden dish 16 that has radial space; Mix rotation envelope 12,13,14 grades that make better each strand of separation air-flow and form the integral body of a pump and heat exchanger combination.Heat exchange surface 1 among Fig. 2-1 and Fig. 2-2 is radially arranged and is fixed on coaxial garden tube 2 and 3 around axle by thin sheet metal or plastic sheet, and its adjacent space has been stipulated the paired passage 4 and 5 among Fig. 2-2.Gas discrepancy end member 6,7,8,9 anti-title geometric configuration is made adjacency channel 4,5 gas flow are reverse pumping, all hot switching path end members distribute up and down equably as garden conical ring pipe and the both sides antisymmetry be arranged on and revolve around the axle, it separates homonymy gas feed and outlet.The place, gateway of each passage is equipped with flow deflector 17, respectively to shut half and both sides are sealed be alternative expression for upper and lower adjacency channel can to see flow deflector from Fig. 2-2, this can reflect in Fig. 2-7, and air is guided the outside into from end member 7 again from end member 6 admission passages 4 during rotation; Another strand then guided the outside into from end member 9 again from end member 8 stand in channels 5.The outlet end member connects to annular fixed-piping 11 by rotation envelope 12 air is discharged, pipeline 11 and the garden dish 16 that has a radial hole are symmetrical for both sides, they and shell 10 are the moving part of maintaining static of heat exchanger together, and air then is to enter by 16 gap.To have used rotation envelope 13 in order separating better between the discharge gas that makes different temperatures after the heat exchange, to have used rotation envelope 14 for import and exit gas are effectively isolated.

The core of gas-gas-heat exchanger can also be implemented by following several schemes.

As Fig. 2-3, shown in the 2-4, constitute the outer tube that comprises inner pipe passway 5 by coaxial garden tube 2 and 3, outer tube is a passage 4, adjacency channel is alternately arranged and the core of formation heat exchanger, gas reverse flow between interior pipe and outer tube.Passage 5 is by two endplates 18, is actually two circular cones, in pipe in one by one is embedded at certain intervals between garden tube 3 and the outer garden tube 2.Gas enters inner pipe passway 57 discharges from the another port again by port 6; Another strand gas then enters outer tube passage 4 by port 8 and discharges from port 9.

Shown in Fig. 2-5, the wedge framework that the core of heat exchanger also can be arranged by a pair of opposing connection axle, i.e. gas passage 4 and 5, being arranged to adjacent frame interchannel gas is the adverse current pumping, and heat exchange walls 1 constitutes.The exchange wall material is metal or plastic tab, and framework can be the raising heat exchanger effectiveness with batten or plastics, arranges to have the parting bead 17 of guiding gas flow in the framework, with pressure welding or gluing method paired framework is connected to core integral body.The concrete size of a suggestion is as follows: wall 1 is the aluminium foil or the plastic foil of 0.02 to 0.03 millimeter of thickness, and area is radially 100 * axial 250 millimeters, and base of frame is 50 millimeters to the distance in axle center, and the diameter that also is heat exchange core is 150 millimeters, long 250 millimeters.Constitute the bar of framework, thickness is 2 millimeters, 6 millimeters of top width, 2 millimeters of bottom widths; 1 millimeter of inner parting bead thickness, gas vent 7 and 9 width are 10 millimeters, import 6 and 8 width are 30 millimeters.According to above-mentioned size, but need 80 pairs of framework passages 4 and 5 to dress up a complete heat exchanger rotary core approximately with regard to tightening seal.

Also have, as Fig. 2-6, shown in the 2-7, radial heat exchange walls 1 among Fig. 2-1 and Fig. 2-2, can be made of corrugated sheet material, the Feng Hegu of these ripples is right after coaxial garden tube 2 and 3, thereby forms adjacency channel 4 and 5 s' isolation, the access port that these corrugated platings form makes gas reverse pumping of energy in adjacency channel by alternately shutting half up and down shown in Fig. 2-7.Be to export to passage between annular water conservancy diversion shrouding 17 and the outer garden tube 2; Annular water conservancy diversion shrouding 17 and by then being the inlet of gas concerning passage between the garden tube 3.

If do not need the occasion of heat exchange only needing to ventilate, above-mentioned gas-gas-heat exchanger simply can be transformed, respectively add a seal ring 20,21 at the import and export two ends of gas.Having the occasion of heat exchange normally, its seal ring position does not change the adverse current pumping of original gas in adjacency channel shown in Fig. 3-1.When seal ring 20,21 along axle extract out from the passage two ends one apart from the time, make homonymy import and export passage UNICOM, and close outlet end member 7 and import end member 6, and force the equidirectional pumping of gas between adjacency channel, promptly the inlet of gas is 8, outlet is 9, becomes simple directed the ventilation, shown in Fig. 3-2.

In fact, seal ring can be made the notched envelope dish of two pairs of different-diameters, as 19 among Fig. 3-3.The envelope dish is installed on the rotating shaft, as long as rotation or turned round a gap position and close or open the passway and just can change gas flow in the adjacency channel.

For using principle that dynamic inertia drives heat exchange in the solution-air system, have essentially note at 2, the one, guarantee that liquid does not leak, next requires liquid not to be detained.Because density of liquid is much bigger with respect to gas, can be with small-bore rotation fluid-tight, the heat exchanging pipe of carrier liquid also can dwindle its cross-sectional area greatly.

Fig. 4-1 is the axial section of solution-air heat-exchange system.This system is by liquid-inlet pipeline 22, and fluid-tight 14 is rotated in import, axle center pipeline 23, and radial isocon 24, tubular heat dissipation element 25, the box 28 that confluxes, outlet rotation fluid-tight 12, rotating vane 26, centrifugal cavity 27 and liquid outlet pipeline 11 constitute; Above-mentioned each element order is the hot liquid path of flowing through just, wherein removes inlet pipeline 22, centrifugal cavity 27 and export 11 for outside the fixing non-rotary part, and all the other each several parts can make its rotation by any power-equipment starting.The gap of cold air by radial isocon 24 enters heat exchanger around axle center pipe 22, to the space, pump and heat exchanger are the integral body that organically combines to last hot-air from the interstitial row of 25 of the bigger tubular heat dissipation elements of axle radius.The tubular heat dissipation element 25 of heat exchange is to have many metal fin 30 rows to put on pipeline to constitute; Fin can have two kinds of frame modes: whole garden annular, see Fig. 4-3 and the garden sheet shape that is dispersed on each pipeline 25, and see Fig. 4-4.Fig. 4-2 is the schematic diagram of radial isocon.Box 28 roles that conflux are that the liquid with each hot channel 25 of flowing through is collected to ring exit 29, when liquid leads to when maintaining static moving centrifugal cavity 27 by rotation fluid-tight 12, because of heat-exchange tube 25 is contracted to small radii from the macro-axis radius, this moment the liquid possible loss that rotating the segment angle momentum, for making its unlikely viscous flow, by rotating vane 26 increase its angular momentums and after stationary exit pipeline 11 leave.

As the embodiment of liquid-liquid heat exchanger as shown in Figure 5, it is by liquid-inlet pipeline 31 and 35, import rotation fluid-tight 32 and 36, heat exchange garden cylindrical surface 40, interior garden tube 39 outer garden tubes 41 formed cavity shape passages, the radial radiation shape rack plate 42 of fixing inside and outside garden tube and 43 and outlet rotation fluid-tight 33 and 37, exit passageway 34 and 38 formations.Hot liquid pumps into from 31, leaves from managing 34; Cold liquid pumps into and leaves from 38 from managing 35, when garden tube 39,40,41 when being rotated by driven by motor, and the liquid that pumps into obtains angular momentum and the separately inner surface 40 of two strands of different temperatures liquid by power activation carries out heat exchange, and pipeline 31,35,34,38th, fixed.
