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 circulating pump.
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 above-mentioned power heat 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 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.
