Abstract
The freeze proof anticorrosion heat pipe of a kind of independent phase-change heat transfer formula, comprise surface treated housing, anticorrosion heat conducting coating, be formed at the independent air chamber in surface treated housing and fill the working medium in air chamber, this heat pipe outer surface is coated anticorrosion heat conducting coating, there is evaporation ends and condensation end, in surface treated housing, be provided with internal channel and side trench, internal channel is located between evaporation ends and condensation end, side trench is located in evaporation ends and in condensation end, press close to surface treated housing parts sidewall, each air chamber independently separates.Owing to adopting internal channel and side trench, form independently phase-change heat transfer passage, can work separately and do not affect other passages, while also having avoided the liquid working substance phase transformation in air chamber, produce too much incoagulable gas.Meanwhile, this heat pipe is evenly coated appropriate anticorrosion heat conducting coating at surface of shell, can strengthen this device weatherability, and improves its heat conductivility.
Description
Technical field
The utility model relates to a kind of thermal transfer devices, particularly a kind of independent phase-change heat transfer and freeze proof corrosion-resistant device realized.
Background technology
As far back as nineteen forty-four, first the R.S. Gauler of Ohio, USA general purpose engine company proposes the principle of heat pipe.From people such as U.S. Grover in 1964, proposed to be independently similar to the heat transfer element of R.S. Gauler, and be named heat pipe, so far the history of existing 40 years.The emphasis of heat pipe application is transferred to ground by space flight, by industrial applications, expands to the product for civilian use.Heat pipe has various shape and size, for the chip of cooling electronic device, the CPU of notebook, high power transistor, silicon controlled rectifier (SCR), duplicator internal heat generation element, transmit solar heat.
Particularly the heat pipe of capillary structure, adopt phase-change heat transfer, thereby its thermal conductivity factor is high, than metal fever conductors such as silver, copper, aluminium, exceeds several orders of magnitude.In addition, heat pipe is applied in solar energy heat utilization field, also have start fast, good heat-transfer, good antiscale property, the advantage such as use is reliable, resistance to frost is good.
At present, the heat transfer path that capillary structure in heat pipe is used is less, and being opposite heat tube heat conductivility quality, the passage of its capillary structure plays a decisive role, make each portion temperature variation of heat pipe work approach uniformity, once passage wherein stops up, internal working medium refluxes, run into excessive resistance or produce too much incoagulable gas, capillary force is inoperative, and heat conductivility declines greatly.And heat pipe tubing adopts the metals such as copper, aluminium more, tube outer surface does not deal with, and is easily corroded, and weatherability is not good.
Summary of the invention
The utility model, for above-mentioned technical problem, is necessary to provide a kind of and can realizes independent phase-change heat transfer and freeze proof corrosion-resistant heat pipe simultaneously.
Technical scheme: the freeze proof anticorrosion heat pipe of a kind of independent phase-change heat transfer formula, comprise surface treated housing, anticorrosion heat conducting coating, be formed at the independent air chamber in surface treated housing and fill the working medium in air chamber, this heat pipe outer surface is coated anticorrosion heat conducting coating, there is evaporation ends and condensation end, in surface treated housing, be provided with internal channel and side trench, internal channel is located between evaporation ends and condensation end, side trench is located in evaporation ends and in condensation end, press close to surface treated housing parts sidewall, each air chamber independently separates.
The freeze proof anticorrosion heat pipe of this independent phase-change heat transfer formula is owing to adopting internal channel and side trench, working medium and die material can be compatible for a long time, different channel air chamber and liquid working substance are separated, form independently phase-change heat transfer passage, can work separately and not affect other passages, even if wherein a certain air chamber and gutter channel are extruded distortion, result in blockage, other passages can work in the same old way, and carry out repetition degasification, while also having avoided the liquid working substance phase transformation in air chamber, produce too much incoagulable gas.Meanwhile, the freeze proof anticorrosion heat pipe of this independent phase-change heat transfer formula is evenly coated appropriate anticorrosion heat conducting coating at surface of shell, can prevent that housing outer surface is corroded, and strengthens this device weatherability, and improves its heat conductivility, respond well.

Fig. 2 is the axial section schematic diagram of the freeze proof anticorrosion heat pipe of independent phase-change heat transfer formula of the present utility model.
The 10th, heat pipe, the 11st, surface treated housing, the 12nd, internal channel, the 13rd, side trench, the 14th, air chamber, the 15th, working medium, the 16th, anticorrosion heat conducting coating, the 111st, evaporation ends, the 113rd, condensation end.
The specific embodiment
This heat pipe 10 comprises surface treated housing 11, anticorrosion heat conducting coating 16, forms air chamber 14 in the inner and fill the working medium 15 in air chamber 14, these heat pipe 10 outer surfaces are coated anticorrosion heat conducting coating 16, there is evaporation ends 111 and condensation end 113, be located between evaporation ends 111 and condensation end 113 and be provided with internal channel 12, side trench 13 is located in evaporation ends 111 and in condensation end 113 and is provided with side trench 13, press close to surface treated housing parts sidewall, each air chamber is separated.
Heat pipe 10 vertically or lay with certain inclination angle, the thermal source of contact uniform temperature, its evaporation ends 111 absorbs heat energy, and thermal energy conduction is arrived to the working medium 15 in air chamber 14, working medium 15 reaches explosive evaporation rapidly after boiling point, through the of short duration response time, pass on condensation end 113, be then liquefied as liquid, discharge a large amount of heat energy, owing to having removed incoagulable gas, increased the effective length of condensation end 113, improved heat conductivility.After working medium 15 phase transformations at condensation end 113 to being back to evaporation ends 111 between top, carry out again heat cycles next time.Anticorrosion heat conducting coating 16 outside surface treated housing 11 is dried, places for a long time under working environment, strengthen the weatherability of heat pipe 10.
