Description
Technical field
The utility model relates to technical field of heat exchange, specifically, relates to a kind of novel heat pipe heat exchanging system, particularly a kind of split type two-phase flow heat-pipe apparatus with Two-phase fluid pump.
Background technology
Heat pipe is as high-performance heat transfer components, and the application in engineering is day by day universal.Heat pipe is not only widely used at aspects such as waste heat recovery, electronic devices and components are cooling, 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 is lower, heat pipe can also substitute current air-conditioning system, as the heat radiation temp-controlling element of electronic equipment, power equipment, computer floor, communications equipment room.
Heat pipe has various structures form, also has multiple sorting technique.Backflow power by liquid-working-medium is classified, and heat pipe can be several large classes such as surface tension heat pipe, gravity assisted heat pipe, centrifugal heat pipe, pulsating heat pipe and power heat pipe.The surface tension withdrawing fluid that surface tension heat pipe produces liquid by liquid-sucking core; Gravity assisted heat pipe is by gravity reflux liquid; Centrifugal heat pipe is by rotating the centrifugal force withdrawing fluid producing; The expansive force that pulsating heat pipe produces bubble by evaporation promotes circulation; 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 applicable to miniaturization, microminiaturization, its shortcoming be circulation power a little less than, be not suitable for high-power, long-distance transmissions heat.
Power heat pipe refers to the hot-pipe system of additional circulation driving force, and this driving force is usually expressed as a kind of fluid circulation pump of particular form.The basic structure of power heat pipe comprises evaporimeter, condenser, fluid reservoir, four parts of circulating pump, and they are interconnected to constitute a closed circulation loop, adds working media just to form a complete power heat pipe after vacuumizing.During power heat pipe work, circulating pump is extracted liquid as received basis out from fluid reservoir and is sent into evaporimeter, liquid as received basis is subject to thermal evaporation to become gas in evaporimeter, gas as received basis enters condenser by conduit, and in condenser the cooling liquid that condenses into, liquid working matter flows back to fluid reservoir through catheter again, thereby completes 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 applicable to high-power, long-distance transmissions heat.
Under the duty that above-mentioned power heat pipe system wants to realize ideal, its condenser must have good gas-liquid separating function.If working medium gas-liquid separation is insufficient in condenser, gas working medium will constantly enter fluid reservoir and form accumulation.This phenomenon can cause two kinds of results: the one, if the total gas as received basis volume in system is less than 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 in circulating pump, evaporimeter, condenser, flow is single liquid phase working fluid, and whole system forms liquid-circulating state; Under liquid recurrent state, not evaporation and condensation process, system has not just had adopting heat pipes for heat transfer function yet, once and the liquid-circulating state forming can not recover normal down in working order, only have shutdown more again start could recover normal.The 2nd, if the total gas as received basis volume in system is greater than fluid reservoir volume, the accumulation of gas working medium in fluid reservoir, finally cause gaseous working medium to be full of fluid reservoir, at this moment circulating pump will suck gas, and the circulating pump of power heat pipe system is normally for carrying liquid to design, the suction of gas can cause pump pressure sharply to decline, thereby causes circulation power not enough, and causes evaporimeter feed flow difficulty.In order to make condenser there is gas-liquid separating function thoroughly, condenser conventionally adopt diameter larger, parallel with one another, erect calandria structure, this structure radiating efficiency is lower, and volume is larger.In a word, there is the problem of gas-liquid separation difficulty and circulation power deficiency in current power heat pipe.Just because of this, power heat pipe is not widely applied.
Summary of the invention
A kind of novel heat pipe technology that the utility model provides---a kind of two-phase flow power heat pipe device, exactly in order to solve gas-liquid separation that current driving force heat pipe when work exist not thoroughly and the problem of circulation power deficiency.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:
A two-phase flow power heat pipe device, comprises condenser, evaporimeter, two-phase flow liquid storage flow straightener, Two-phase fluid pump, wireway, catheter and circuit controling element; Described condenser and evaporimeter are the micro-channel heat exchangers of aluminum; The whole lateral surfaces of described evaporimeter and horizontal plane have an angle of inclination to place; Described Two-phase fluid pump is the little compressor of positive displacement that can simultaneously carry gas and liquid; Described two-phase flow liquid storage flow straightener comprises a fluid reservoir, two external-connected ports and is positioned at the gas-liquid two-phase flow pipe of fluid reservoir inside; Two external-connected ports of described two-phase flow liquid storage flow straightener, are respectively the inflow port of cold-producing medium and the outflow port of cold-producing medium; Described gas-liquid two-phase flow pipe is the straight tube of a both ends open, on the caliber of gas-liquid two-phase flow pipe, is equipped with return port; A port of described gas-liquid two-phase flow pipe is connected in the cold-producing medium outflow port of described two-phase flow liquid storage flow straightener, the liquid level bottom of its another port liquid refrigeration working medium in two-phase flow liquid storage flow straightener; The liquid level top of the return port of described gas-liquid two-phase flow pipe liquid refrigeration working medium in two-phase flow liquid storage flow straightener.Evaporimeter, condenser, two-phase flow liquid storage flow straightener and Two-phase fluid pump connect into the two-phase flow power heat pipe device of an one-way circulation by said sequence by mutual connecting pipe like this.
In the time of must considering hot-pipe system operation for existing heat pipe, the poor problem of high and low position and the cold-producing medium of two heat exchangers are carried problem at a distance, in this system, added transmitting power (Two-phase fluid pump), after adding transmitting power, the state operation problem of liquid refrigerant and gaseous refrigerant is just improved, the power of whole heat pipe is no longer just that small power that relies on gas-liquid self attributes to produce completely of existing heat pipe, but the machine power that Two-phase fluid pump produces---can make gaseous refrigerant to the motion of pipeline bottom, liquid refrigerant moves to pipeline top; When adding Two-phase fluid pump, also solved the problem of heat transmitting range, because there has been transmitting power, power when this system is carried is at a distance no longer that the small pressure reduction producing while leaning on the interior gaseous state condensing agent evaporation of system is realized, but operate by the machine power that the Two-phase fluid pump adding in system produces, so when the evaporimeter in system (temperature end) and condenser (low-temperature end) are distant, also can adopt comparatively energy-conservation thin heat pipe to transmit cold-producing medium.
In order to solve the inefficiency problem thoroughly not producing because of gas-liquid separation that adds that Two-phase fluid pump occurs later, in this system, added two-phase flow liquid storage flow straightener, by the fluid reservoir in two-phase flow liquid storage flow straightener, gas-liquid mixed refrigerant in system pipeline is filtered, by the return port in two-phase flow liquid storage flow straightener, to the whole system in varying environment, there is a stable two-phase flow to circulate, when realizing gas-liquid separation, storage and shunting, improved efficiency of heat pipes like this.
By the design that adds two-phase flow liquid storage flow straightener to take over problem with each equipment, just solved the separated halfway problem of gas-liquid cold-producing medium in existing heat pipe, not only improved the heat exchange efficiency that every secondary device circulates a week, and realized the stability of whole system circulation, again by the gas-liquid two-phase flow pump adding in system, operation power is provided to whole hot-pipe system, this is the poor and fed distance problem of the high and low position of two heat exchangers when having solved the operation of conventional heat pipe system also, thereby reduced the service condition restriction of equipment, increase substantially the heat exchange efficiency of heat pipe, and whole system apparatus structure used is simple, environmental friendliness.
