Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
Shown in Figure 1, according to embodiments of the invention, heat abstractor comprises liquid storage cylinder 1, gas-liquid separation chamber 2, gas-liquid rising passway 3 and back flow channel 4.Liquid storage cylinder 1 is arranged on bottom heat abstractor, for storing working medium of easily vaporizing.Gas-liquid separation chamber 2 is arranged on heat abstractor top, carries out gas-liquid separation for commute vaporization working medium.Gas-liquid rising passway 3 is communicated with between liquid storage cylinder 1 and gas-liquid separation chamber 2, and be arranged on heat abstractor with treat the side that thermal component 7 contacts.Back flow channel 4 is communicated with between liquid storage cylinder 1 and gas-liquid separation chamber 2, and is arranged on the side away from gas-liquid rising passway 3 of heat abstractor.Liquid storage cylinder 1, gas-liquid separation chamber 2, gas-liquid rising passway 3 and back flow channel 4 form airtight circulation canal in heat abstractor.
When this heat abstractor works, in liquid storage cylinder 1, splendid attire is easily vaporized working medium, when reaching a certain height until the temperature of thermal component 7, heat will be passed in easy vaporization working medium by heat transfer, undergo phase transition after working medium is heated and flow in gas-liquid rising passway 3, and enter in gas-liquid separation chamber 2 and carry out gas-liquid separation, the liquid separated continues circulation through back flow channel 4, treat thermal component 7 to lower the temperature, gas then again becomes liquid after condensation, is then back in liquid storage cylinder 1.By making easily to vaporize, working medium becomes gas-liquid two-phase and makes the mode of working medium at circulation canal internal circulation flow of easily vaporizing, can will treat that heat that thermal component 7 produces takes other positions of heat abstractor to rapidly, and distributed by heat, therefore, it is possible to improve radiating efficiency.This construction for heat radiating device is simple, and heat exchange efficiency is high, safe and reliable, can play good thermolysis.Due in radiation processes, flowing mainly through easily the vaporize phase transformation of working medium in airtight circulation canal and liquid refrigerant is dispelled the heat, commute vaporization working medium can not cause loss, and there is no complicated radiator structure, therefore can reduce the cost of whole heat abstractor.
Preferably, heat abstractor also comprises the airlift pump arranged corresponding to gas-liquid rising passway 3, airlift pump can when heat abstractor works, accelerate the generation speed of easily vaporization working medium bubble, and the Working fluid flow speed accelerated in gas-liquid rising passway 3, make working medium can will treat that the heat that thermal component 7 produces is taken away more rapidly, improve the exchange rate of heat abstractor.
Preferably, airlift pump is arranged on the bottom of gas-liquid rising passway 3, and the bubble that working medium is produced rises in the gas-liquid separation chamber 2 at top from the bottom of gas-liquid rising passway 3, therefore, it is possible to more effectively take away the heat treating that thermal component 7 produces.
Back flow channel 4 can be one or more, in the present embodiment, many back flow channel 4 intervals are arranged, and can accelerate the back-flow velocity of working medium, ensure that the liquid after gas-liquid separation can be back in liquid storage cylinder 1 as early as possible, make can to remain in liquid storage cylinder 1 that enough liquid state are easily vaporized working medium.
Heat abstractor also comprises condensation structure, condensation structure is arranged in gas-liquid separation chamber 2, can cool the gas being positioned at gas-liquid separation chamber 2 in time, not only can accelerate the heat loss in working medium, the air pressure in gas-liquid separation chamber 2 can also be reduced, avoid the air pressure in gas-liquid separation chamber 2 too high and the flowing of commute vaporization working medium causes adverse effect, working medium can be entered more swimmingly in gas-liquid separation chamber 2 after being heated.
In the present embodiment, heat abstractor also comprises condensation chamber 6, and condensation chamber 6 is arranged on the side of back flow channel 4 away from gas-liquid rising passway 3, and is communicated with gas-liquid separation chamber 2 with liquid storage cylinder 1, is provided with condenser pipe 5 in condensation chamber 6.Condensation chamber 6 and gas-liquid separation chamber 2 separate, and are used for specially carrying out condensation to the gas in gas-liquid separator, make it flow back in liquid storage cylinder 1 and participate in heat exchange circulation, can improve the exchange rate of heat abstractor further.
Heat abstractor can be any heat transfer material composition, dispels the heat in time can treat thermal component 7.Preferably, described heat abstractor is metal structure, and metal structure has good heat-conductive characteristic, therefore can play good radiating effect.
The specific works process of heat abstractor is as follows:
When working until thermal component 7 and starting to heat up, treat that the delivered heat of thermal component 7 is to the liquid working substance of liquid storage cylinder in heat abstractor 1.
When treating that thermal component 7 caloric value is less, when temperature is lower, in device, liquid working substance can not seethe with excitement, and heat is now conducted to air (surrounding environment) by the heat conduction of metal and liquid.
When treating that thermal component 7 caloric value is comparatively large, when temperature reaches working medium boiling temperature, heat is now except conducting to except air by metal heat-conducting, the working medium in heat abstractor comes to life, and takes away a large amount of heats.When working medium is seethed with excitement, (bubble that working medium boiling is formed rises to produce bubble pumping effect in the airlift pump of heat abstractor, the liquid promoting its top in the process risen reaches higher level height), the liquid working substance of part heat is brought in the gas-liquid separation chamber 2 above heat abstractor.The liquid working substance entering the heat of gas-liquid separation chamber 2 to be back to by back flow channel 4 in the liquid storage cylinder 1 below heat abstractor through Action of Gravity Field, while flowing through back flow channel 4, with ambient air heat exchange, reduces Temperature of Working; The gas working medium entering the heat of gas-liquid separation chamber 2 then enters in condenser pipe 5, liquid working substance is condensed into by heat being passed to surrounding air in condenser pipe 5, and be back in liquid storage cylinder 1 by Action of Gravity Field, again treated that the heat that thermal component 7 distributes heats, constantly circulated.
By this heat abstractor; make use of metal heat-conducting, liquid phase-change heat transfer and liquid flow heat exchange three kinds of heat-transferring methods; improve radiating effect greatly; make to treat that the heat that thermal component distributes can be discharged in time; can guarantee to treat that thermal component is in rational temperature range of operation always, reach the object that thermal component stable operation is treated in protection.
Certainly, be more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art, under the prerequisite not departing from its general principles, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
