Description
Technical field
The invention belongs to technical field of heat exchange, particularly relate to a kind of multiple branch circuit phase-change heat transfer system.
Background technology
Heat pipe becomes increasingly popular as high-performance heat transfer components, the application in engineering.Heat pipe is not only widely used at aspects such as waste heat recovery, electronic devices and components coolings, and in traditional heat and mass apparatus field, heat pipe has replacement recirculated water, recycle oil and the trend of water vapour heat transfer.When ambient temperature is relatively low, heat pipe can also substitute current air conditioning system, as electronic equipment, power equipment, computer floor, the heat radiation temp-controlling element of communications equipment room.
Heat pipe has various structures form, also has multiple sorting technique.Classifying by the backflow power of liquid-working-medium, heat pipe can be divided into several big 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 liquid is produced by surface tension heat pipe by wick；Gravity assisted heat pipe leans on gravity reflux liquid；Centrifugal heat pipe is by rotating the centrifugal force withdrawing fluid produced；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 has moving component, and its advantage is simple in construction, is suitable for miniaturization, miniaturization, and its shortcoming is that circulation power is more weak, is not suitable for high-power, long-distance transmissions heat.
Power heat pipe refers to that the hot-pipe system of applied cyclic driving force, this driving force are usually expressed as the fluid circulation pump of a kind of particular form.The basic structure of power heat pipe includes vaporizer, airway, condenser, fluid reservoir circulating pump and six parts of catheter, and they are interconnected to constitute a closed circulation, adds working media and just constitute a complete power heat pipe after evacuation.During power heat pipe work, circulating pump is extracted liquid working media out from fluid reservoir and is sent into vaporizer, liquid working media is become gas by thermal evaporation in vaporizer, gas working dielectric enters condenser by airway, and cooling condenses into liquid within the condenser, liquid-working-medium flows back to fluid reservoir through catheter again, thus 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 suitable for high-power, long-distance transmissions heat.
Above-mentioned dynamic heat pipe system wants to realize under preferable duty, and its condenser must have good gas-liquid separating function.If working media gas-liquid separation is insufficient within the condenser, gas working dielectric will constantly enter fluid reservoir and form accumulation.This phenomenon can cause two kinds of results: one is if the total gas working dielectric volume in system is less than fluid reservoir volume, gas working dielectric accumulation in fluid reservoir, ultimately result in whole gaseous working medium and all run up to fluid reservoir, at this moment flow in circulating pump, catheter, vaporizer, airway, condenser is single liquid phase working media, and whole system forms liquid recurrent state；Under liquid recurrent state, not evaporation and condensation process, system is the most just without adopting heat pipes for heat transfer function, and once forms liquid recurrent state and lower in working order can not recover normal, only shuts down to turn back on again and could recover normal.Two is if the total gas working dielectric volume in system is more than fluid reservoir volume, gas working dielectric accumulation in fluid reservoir, ultimately result in gaseous working medium and be full of fluid reservoir, at this moment circulating pump will suck gas, and what the circulating pump of dynamic heat pipe system typically designed for conveying liquid, the suction of gas can cause pump pressure drastically to decline, thus causes the problem that circulation power is not enough, closed circuit gas liquid ratio is uneven and heat distribution is uneven.In order to make condenser have gas-liquid separating function completely, condenser generally use be relatively large in diameter, parallel with one another, erect calandria structure, this structure radiating efficiency is relatively low, and volume is relatively big, and cannot realize the demand of one-to-many user.In a word, the problem that current power heat pipe exists gas-liquid separation difficulty, circulation power is not enough, closed circuit gas liquid ratio is uneven, heat distribution is uneven and cannot realize one-to-many user.Just because of this, power heat pipe is not widely applied.
