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 power heat pipe system.
Background technology
Heat pipe is as high-performance heat transfer components, and the application in engineering is day by day universal.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 the various structures form, and multiple sorting technique is also arranged.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 the 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 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.
Power heat pipe refers to add the hot-pipe system of 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, vacuumizes rear adding working media and just consists of a complete power heat pipe.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 subjected to thermal evaporation to become gas in evaporimeter, the gas as received basis enters condenser by conduit, and cooling condenses into liquid in condenser, liquid working matter flows back to fluid reservoir through catheter again, thereby finishes 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 the above-mentioned power heat pipe circulatory 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 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 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-circulating state; Under liquid recurrent state, not evaporation and condensation process, system has not just had the adopting heat pipes for heat transfer function yet, and in case the liquid-circulating state that forms 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 the system is greater than the 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 descend, thereby causes circulation power not enough, and causes evaporimeter feed flow difficulty.In order to make condenser have thoroughly gas-liquid separating function, condenser usually 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 present power heat pipe.Just because of this, power heat pipe is not widely applied.

The poor problem of high and low position and the cold-producing medium of two heat exchangers are carried problem at a distance in the time of must considering the hot-pipe system operation for existing heat pipe, added transmitting power (compressor) 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 compressor 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 compressor, 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 produces with the compressor that adds in the system operates, so when the evaporimeter in the system (temperature end) and condenser (low-temperature end) are distant, also can adopt comparatively energy-conservation thin heat pipe to transmit cold-producing medium.
Add the inefficiency problem that does not thoroughly produce because of gas-liquid separation that occurs behind the compressor in order to solve, fluid reservoir and gas-liquid two-phase flow pipe have been added in this system, by fluid reservoir gas-liquid mixed refrigerant in the system pipeline is separated, and the liquid state cold-producing medium after separating has been got back in the evaporimeter by gas-liquid two-phase flow pipe and compressor, has improved efficiency of heat pipes like this when realizing gas-liquid separation.
The utility model compared with prior art, the gas-liquid cold-producing medium separates halfway problem in the existing heat pipe with regard to having solved in design by adding fluid reservoir and fluid reservoir and each equipment adapter problem, improved the circulate refrigerating efficiency in a week of every secondary device, the compressor by adding in the system again, operation power is provided for 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, increased substantially the heat exchange efficiency of heat pipe.
