Description
Technical field
The present invention relates to technical field of heat exchange, specifically, relate to a kind of novel heat pipe heat exchanging system, particularly a kind of separated heat pipe device with circulating pump.
Background technology
Heat pipe is as high-performance heat transfer components, and is universal day by day in application in engineering.Heat pipe not only is widely used at aspects such as waste heat recovery, electronic devices and components coolings, and in traditional heat and mass apparatus field, the trend that heat pipe has alternative recirculated water, recycle oil and water vapour to conduct heat.When environment temperature was low, heat pipe can also substitute present air-conditioning system, as the heat radiation temp-controlling element of electronic equipment, power equipment, computer floor, communications equipment room.
Heat pipe has multiple version, and multiple sorting technique is also arranged.Backflow power by liquid-working-medium is classified, and heat pipe can be several big type of surface tension heat pipe, gravity assisted heat pipe, centrifugal heat pipe, pulsating heat pipe and power heat pipe etc.The surface tension withdrawing fluid that the surface tension heat pipe leans on wick that liquid is produced; Gravity assisted heat pipe leans on gravity reflux liquid; Centrifugal heat pipe is by rotating the centrifugal force withdrawing fluid that produces; Pulsating heat pipe promotes circulation by the expansive force that evaporation produces bubble; The common feature of these heat pipes is that inside heat pipe does not have moving component, and its advantage is simple in structure, is fit to miniaturization, microminiaturization, its shortcoming be circulation power a little less than, be not suitable for high-power, long-distance transmissions heat.
The power heat pipe is meant the hot-pipe system that adds the circulation driving force, and this driving force shows as a kind of fluid circulation pump of particular form usually.The basic structure of power heat pipe comprises evaporimeter, condenser, fluid reservoir, four parts of circulating pump, and they interconnect and constitute a closed circulation loop, vacuumizes back adding working media and just constitutes a complete power heat pipe.During the work of power heat pipe; Circulating pump is extracted liquid as received basis out from fluid reservoir and is sent into evaporimeter, and liquid as received basis receives thermal evaporation to become gas in evaporimeter, and the gas as received basis gets into condenser through conduit; And cooling condenses into liquid in condenser; Liquid working matter flows back to fluid reservoir through catheter again, thereby accomplishes the heat pipe circulation, and heat flows to the low-temperature heat source of condenser end from the high temperature heat source of evaporator end simultaneously.The advantage of power heat pipe is that circulation power is powerful, is fit to high-power, long-distance transmissions heat.
Under the duty that above-mentioned power hot-pipe system wants to realize ideal, its condenser must have good gas-liquid separating function.If the working medium gas-liquid separation is insufficient in condenser, gas working medium will constantly get into fluid reservoir and form accumulation.This phenomenon can cause two kinds of results: the one, if the total gas as received basis volume in the system is less than the fluid reservoir volume; The accumulation of gas working medium in fluid reservoir; Finally cause whole gaseous state as received bases all to run up to fluid reservoir; What at this moment flow in circulating pump, evaporimeter, the condenser is single liquid phase working fluid, and whole system forms the liquid recurrent state; Under liquid recurrent state, there are not evaporation and condensation process, system has not just had the adopting heat pipes for heat transfer function yet, and the liquid recurrent state that in a single day forms can not recovery be normal down in working order, has only shutdown to start shooting again again and could recover normal.The 2nd, if the total gas as received basis volume in the system is greater than the fluid reservoir volume; The accumulation of gas working medium in fluid reservoir finally causes gaseous working medium to be full of fluid reservoir, and at this moment circulating pump will suck gas; And the circulating pump of power hot-pipe system is normally for carrying liquid to design; The suction of gas can cause pump pressure sharply to descend, thereby causes circulation power not enough, and causes evaporimeter feed flow difficulty.In order to make condenser have gas-liquid separating function completely, condenser adopt usually diameter bigger, parallel with one another, erect calandria structure, this structure radiating efficiency is lower, and volume is bigger.In a word, present power heat pipe exists gas-liquid separation difficulty and the not enough problem of circulation power.Just because of this, the power heat pipe is not applied.
Summary of the invention
A kind of novel heat pipe technology provided by the invention---a kind of power heat-pipe apparatus is exactly in order to solve the thorough and not enough problem of circulation power of the gas-liquid separation that exists when the current driving force heat pipe is worked.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopted is following:
A kind of power heat-pipe apparatus comprises condenser, evaporimeter, returns liquid device, circulating pump, fluid reservoir and circuit controling element; The air inlet of said condenser connects fluid reservoir; Its both interfaces are positioned on the working media liquid level of fluid reservoir; The gas outlet of evaporimeter connects fluid reservoir; Its both interfaces are positioned on the working media liquid level of fluid reservoir, and the liquid feeding end that returns liquid device inserts in the fluid reservoir, and its both interfaces are positioned under the fluid reservoir working media liquid level; Circulating pump is installed in back after the meet of liquid device outlet end and condenser outlet end, inserts the liquid feeding end of evaporimeter again; Said circuit controling element is being controlled the unlatching and the operating condition of circulating pump in the system; During this system works; Condenser contacts with low-temperature heat source, and gaseous working medium receives the cooling of low-temperature heat source and is condensed into liquid in condenser, and emits heat; The liquid-working-medium that condensation forms is under the drive of circulating pump; They enter into evaporimeter from condenser, and evaporimeter contacts with high temperature heat source, and liquid working media receives the heating of high temperature heat source and is evaporated to gas in evaporimeter; And absorption heat; Evaporating the gas that forms does not have the mutual mixing in flow at high speed of evaporated liquid intermediate medium to form the gas-liquid two-phase flow body with part, and they flow out from evaporimeter and get into the fluid reservoir, and the middle working media basis of gas-liquid two-phase flow physical property is separately separated in fluid reservoir; The gaseous state intermediate medium enters into condenser through condenser wireway interface and circulates next time; Liquid intermediate medium is exported from interface through returning liquid device, and the liquid intermediate medium of output and converge from the liquid intermediate medium that condenser comes out and to enter into evaporimeter is simultaneously so just formed a kind of cyclic process of novel energy-conserving heat pipe.
The above fluid reservoir is the high pressure resistant airtight container that an outer surface is provided with thermal insulation layer, and the function of fluid reservoir is to realize the gas-liquid separation and storage working media of periodic duty medium; The fluid reservoir volume size should be complementary with the volume of evaporimeter and condenser, and its volume should be the volume greater than evaporimeter, and less than the total measurement (volume) of the pipeline of evaporimeter, condenser and whole system; The shared volume of intrasystem working media liquid should be the volume greater than evaporimeter, but less than the volume sum of evaporimeter and fluid reservoir; The mode of fluid reservoir realization gas-liquid separation can be selected simple gravity settling separation, also can filter screen or baffle plate be set at evaporimeter and fluid reservoir interface, to realize that silk screen separates or baffling separates.
The above circulating pump should be selected the positive displacement gas-liquid two-phase flow circulating pump that can carry gas and liquid simultaneously for use; Can elect gear pump, lobe pump, screw pump, rotopiston pump, reciprocating piston pump as; Gaseous refrigerant and liquid refrigerant can be passed through simultaneously, and can realize the regulating system heat output through regulating pump flow.
The above returns liquid device can be the adjustability valve of controllable flow amount; It can be the pipeline in a certain size cross section; It also can be a hole for back flow; Effect is that the refrigerant flow through returning liquid device is no more than through 1/3rd of the total refrigerant flow of circulating pump, and allocation optimum is that cold-producing medium is sixth to three/one of the total cold-producing medium of three-way pipe output through the size of returning liquid device.
The above returns liquid device can be the vertical catheter in a certain size cross section; This vertical catheter is straight as far as possible, and highest point can not exceed the height of liquid storage tank level on the whole pipe vertical direction, and requires the top of fluid reservoir at three-way pipe; Make both have certain altitude poor; So that the liquid storage pot liquid is delivered to evaporimeter because the gravity effect is back to three-way pipe through this vertical catheter through circulating pump, circulates.The length that this catheter should select fluid reservoir to be complementary to the distance of three-way pipe; Its flow velocity has the cross section of its inlet to control, and makes cold-producing medium be no more than three-way pipe by fluid reservoir through the flow that returns liquid device inflow three-way pipe and always flows out 1/3rd of refrigerant flow.
The above returns liquid device can a hole for back flow; The pore size of its hole for back flow is suitable, and the flow that makes the interior refrigerant liquid of fluid reservoir get into hole for back flow is no more than and flows to 1/3rd of output refrigerant flow, and it is positioned at correct position on the condenser catheter; The pipeline of this matching requirements condenser catheter passes fluid reservoir; And the pipeline of condenser catheter is in liquid storage tank level bottom, as close as possible fluid reservoir bottom, its position, so that the liquid refrigerant that stores in the fluid reservoir is because the cold-producing medium that the effect of gravity and inside and outside differential pressure is exported through hole for back flow and condenser outlet end converges at the condenser catheter; Deliver to evaporimeter through circulating pump, circulate.
Said circuit controling element; Mainly be some variations in temperature of monitoring hot environment and low temperature environment through some temperature testing equipments; When the temperature difference between hot environment end and the low temperature environment end surpasses certain value, will control the unlatching of circulating pump automatically, this system has just begun work, when the temperature difference between hot environment end and the low temperature environment end will controlled closing of circulating pump during less than certain value automatically; Owing to do not satisfied condition of work, this system just quits work.
The high and low position difference problem and the remote transportation problem of cold-producing medium of two heat exchangers in the time of must considering the hot-pipe system operation to existing heat pipe; Added transmitting power (circulating pump) in this system; After adding transmitting power; The state operation problem of liquid refrigerant and gaseous refrigerant just is improved; The power of whole heat pipe just no longer is the sort of small power that relies on the gas-liquid self attributes to produce fully of existing heat pipe, but the machine power that circulating pump produces---can make gaseous refrigerant to the motion of pipeline bottom, liquid refrigerant moves to pipeline top; Also solved the problem of heat transmitting range when adding circulating pump; Because transmitting power has been arranged; Power when this system carries at a distance no longer is to lean on the small pressure reduction that produces when the gaseous state condensing agent evaporates in the system to realize; But the machine power that the circulating pump that adds in the using system produces operates, so far the time, also can adopt comparatively energy-conservation thin heat pipe transmission cold-producing medium with condenser (low-temperature end) distance when the evaporimeter in the system (temperature end).
Add the inefficiency problem that does not thoroughly produce because of gas-liquid separation that occurs behind the circulating pump in order to solve; Add fluid reservoir in this system and returned liquid device; Through fluid reservoir gas-liquid mixed refrigerant in the system pipeline is filtered; And the liquid refrigerant after filtering has been got back in the evaporimeter through returning liquid device and circulating pump, when realizing gas-liquid separation, has improved efficiency of heat pipes like this.
The selection of the middle working media that this internal system is filled (system's inner refrigerant); The gas-liquid critical point of working media must remain between the high-temperature region temperature and low-temperature space temperature of operating temperature in the middle of selected; For example when operation temperature area during 30 ° of left and right sides; Can use freon as middle working media, operation temperature area when 100 ° of left and right sides, can water as middle working media; After the intermediate medium of on the other hand working charged into system, internal system pressure must be higher than an atmospheric pressure, can not get in the system to guarantee air, caused system damage; The selection of working media must match with the material of making pipeline in the middle of thirdly being, both can not occur and damage phenomenon mutually.
The gas-liquid cold-producing medium separates halfway problem in the existing heat pipe with regard to having solved in design through adding fluid reservoir and fluid reservoir and each equipment adapter problem; Improved the heat exchange efficiency in each one week of equipment circulation; Gas-liquid circulating pump through adding in the system again; Operation power is provided for whole hot-pipe system; This is high and low position difference and the fed distance problem of two heat exchangers when having solved the operation of conventional heat pipe system also, thereby has reduced the service condition restriction of equipment, increases substantially the heat exchange efficiency of heat pipe.

After system's welded and installed finishes, earlier this system is hunted leak, if find to reveal part, just this system is vacuumized, exhaust after the vacuum just to its inner adding cold-producing medium, the preliminary preparation of system has been accomplished like this.
When the hot environment end did not reach the required environment of system works than the low temperature environment end temperature scope that differs, circuit controling element was closed circulating pump (3) through the signal that temperature detection part spreads out of, and this system is in halted state; When the hot environment end exceeds certain value than low temperature environment end temperature, partly detect signal by detected temperatures in the circuit control, to control circulating pump (3) by control circuit again and opening automatically, whole system just is in normal operating condition.
After this system condensing device (1) absorbs outside energy; Gaseous refrigerant liquefy cold-producing medium; Get in the evaporimeter (4) through pumping of circulating pump (3); And most of liquid refrigerant absorption external heat becomes gaseous refrigerant; The fraction liquid refrigerant is taken out of evaporimeter (4) by gaseous refrigerant and is got into fluid reservoir (5) from interface (53), and the mixed state cold-producing medium carries out first separation in fluid reservoir (4), and the gas refrigerant of separating is through circulate in interface (51) the entering condenser (1) on liquid storage tank level top next time.
Because circulating pump possibly produce in extraction process and take out phenomenon by force; Just from interface (51), extracted the gaseous refrigerant in the fluid reservoir; Make that liquid level changes in the fluid reservoir,, added interface (52) in liquid storage tank level bottom for fear of the generation of this phenomenon; Share the pressure of pumping of part circulating pump (3) through returning liquid choke valve (7); This pipeline also makes in the fluid reservoir (5) and gets into heat absorption evaporation in the evaporimeter (4) again because of the gas-liquid cold-producing medium separates the liquid refrigerant that produces simultaneously, increases work efficiency, and has so just formed the closed circuit of whole system.
The course of work of this system is a kind of desirable duty; Can only be the high temperature energy band to the low temperature place; Can not remove cryogenic energy to the high temperature place; And the job specification that system installs post-condenser (1) and evaporimeter (4) can not change, and can only be sent to low-temperature space to the heat in single place.

The specific embodiment three
In order to make the function transposing of condenser in this system (1) and evaporimeter (4), just condenser (1) plays the effect of evaporimeter under specific environment, and evaporimeter (4) plays the effect of condenser, on the basis of the specific embodiment one, improves.
Circulating pump (3) is changed into the two-way power motor system (such as Roots's motor) that can directly change direction by unidirectional circulating pump; It no longer is a branch road that the pipeline that comes out from the connecting interface (52) of fluid reservoir (5) passes through back liquid device (2); But be divided into two branch roads; Every branch road inserts a check valve; The direction of check valve is outwards to flow out from interface (52); Article one, the port of export of the check valve of installing on the branch road one (21) is linked into three-way pipe (31) between circulating pump (3) and the condenser (1), and the outlet of the check valve of installing on another branch road two (22) is linked into three-way pipe (32) between circulating pump (3) and the evaporimeter (4), and this embodiment simple structure sketch map is as shown in Figure 4.
After system's welded and installed finishes, earlier this system is hunted leak, if find to reveal part, just this system is vacuumized, exhaust after the vacuum just to its inner adding cold-producing medium, the preliminary preparation of system has been accomplished like this.
When the hot environment end did not reach the required environment of system works than the low temperature environment end temperature scope that differs, circuit controling element was closed circulating pump (3) through the signal that temperature detection part spreads out of, and this system is in halted state; When evaporimeter (4) the external high temperature environment end low temperature environment end temperature more extraneous than condenser (1) exceeds certain value; Partly detect signal by detected temperatures in the circuit control; Controlling circulating pump (3) by control circuit again opens automatically; Throughput direction is to carry to evaporimeter (4) end from condenser (1) end, and whole system just is in normal operating condition.
