Description
Technical field
The utility model discloses the board-like pulsating heat pipe of a kind of single face wave.Belong to the heat-exchange apparatus technical field.Be applicable to that the Air conditioner air exchange energy reclaims and the dissipation from electronic devices cooling.
Background technology
Along with expanding economy, air-conditioning uses more and more widely, but energy consumption and air quality perplex consumers in general day by day.According to " IAQ standard " regulation, be to guarantee air quality, need to outdoor exhaust, send new wind to indoor.The new wind of sending into must be handled through the air-conditioning unit and just can reach requirement, and the air that exhaust is treated, the both wants consumed energy.When turnover is indoor, can carry out the primary energy exchange as exhaust and new wind, the air-conditioning unit load will greatly be reduced, save a large amount of energy.Data shows that the new wind load duty is transferred 20～30% of load, and visible new wind load power consumption is surprising.In view of the foregoing, reclaim energy of exhaust air and flow to new wind, seem very necessary and meaningful.
Air conditioner air exchange energy recovery technology is divided into several like this classes at present: fixed-plate heat exchangers, rotary heat exchanger, middle refrigerant type interchanger, heat exchange of heat pipe.Wherein heat exchange of heat pipe has heat exchange efficiency height, no cross pollution, movement-less part because of it, unique advantages such as little different transfer of heat, thereby be widely used in Air conditioner air exchange energy recovery field.From the data of grasping, the heat pipe that uses in the Air conditioner air exchange energy reclaims only is confined to traditional gravity assisted heat pipe at present, and new heat pipe is seldom used such as pulsating heat pipe, and the Air conditioner air exchange energy of announcement reclaims pulsating heat pipe quantity also seldom.
Electronics microelectronic chip, dynamo-electric field IGCT, silicon controlled rectifier (SCR), semiconductor light emitting diode (LED), large scale integrated circuit electronic devices and components such as (LSLchip) use very extensive in producing, living.Produce big calorimetric during these components and parts work, must in time dispel the heat to guarantee device security stable operation.Studies show that the CPU operating temperature is generally-5～+ 70 ℃, surpass this scope, 10 ℃ of the every risings of single semiconductor element temperature, system reliability descends 50%, and the electronic equipment above 55% lost efficacy and caused owing to temperature is too high.As seen, the heat radiation of chip and electronic devices and components is extremely important.
For the heat radiation of components and parts, generally adopt the radiator of following two kinds of forms at present, i.e. aluminium extrusion radiator and band imbibition core heat-pipe radiator.
Aluminium extrusion radiator heat-dissipation principle is, utilize aluminium extrusion radiator metab to contact, the components and parts heat is reached spreader surface, utilize fan that radiator is carried out forced-convection heat transfer again by heat-conducting mode with heater element, make heat reach ambient atmosphere, realize the heat radiation of components and parts.The heat transfer essence of this kind mode is that heat conduction adds convection current, belongs to inefficient heat transfer type.
Band imbibition core heat-pipe radiator has utilized heat-pipe working medium, and heat absorption becomes steam mutually in the hot junction, and the heat release of steam flow cold junction is condensed into liquid, gets back to the hot junction heat absorption by gravity or imbibition core capillary force then, and then the transmission heat that moves in circles.Because phase-change heat transfer, its heat-sinking capability improves a lot than the aluminium extrusion radiator, belongs to the more higher leveled form of cooling electronic component.
Along with the progress of science and technology, practice shows that its heat-sinking capability of aluminium extrusion radiator has performed to the limit, will be difficult to satisfy the needs of components and parts heat radiation future.Though its radiating effect of band imbibition core heat-pipe radiator is stronger than the aluminium extrusion radiator, its heat-sinking capability is about to or has faced a severe test.For example, because of heating influences its steady operation, exaggerate and cause the thing of computer crash, fault even damage to take place by heating with regard to often for notebook computer.
At the electronics microelectronic, just towards the high-power direction develop rapidly of high density, the heat flow density of chip unit are increases progressively rapidly integrated circuit, has reached MW/m at present especially
2Or the above order of magnitude, heating has seriously restricted the further raising of chip dominant frequency, becomes a big bottleneck of electronics microelectronics technology development, seeks a kind of new technology and solves the high heat flux heat dissipation problem, becomes the task of top priority.
Pulsating heat pipe is a kind of new and effective heat transfer element that proposes the nineties in 20th century, is specially adapted to the heat transfer under little space, the little temperature difference, low-temperature heat source, the high heat flux situation.The working mechanism of pulsating heat pipe and traditional gravity assisted heat pipe tool are very different.The tradition gravity assisted heat pipe course of work is, working medium hot junction heat absorption evaporation → steam flow cold junction heat release condensation → liquid cold junction again is back to the circulation heat transfer form in hot junction.Pulsating heat pipe heat transfer cycle process is, working medium hot junction heat absorption evaporation → working medium mobile and exothermic phenomenon (pulsatile impact concussion behavior) → working medium that the vapour-liquid plug produces disappearance at random takes place when flowing to cold junction utilizes self capillarity backflow hot junction to circulate again.Because pulsating heat pipe the vapour-liquid plug occurred and has produced the mobile exothermic process of disappearance at random, cause the diabatic process thermal boundary layer to destroy, thermal resistance greatly reduces, and has greatly strengthened heat pipe heat transmittability.Pulsating heat pipe has self capillary backflow effect in addition, so it is to still have good heat-transfer capability under zero the level at the inclination angle, needs just can finish heat transfer by the imbibition core unlike traditional gravity assisted heat pipe, has simplified technology, has strengthened applicability, flexibility.As a kind of heat transfer original paper that still is in the development phase, it is few that pulsating heat pipe practical technique, product are seen in report.From the data that can inquire about at present, pulsating heat pipe has mainly been carried out some researchs at both direction.A direction is the tubulose pulsating heat pipe.The basic structure of tubulose pulsating heat pipe is snakelike tubulose pulsating heat pipe, and process bends to snakelike formation pulsating heat pipe as required for the elongated metal thin tube with capillary function.This class pulsating heat pipe is mainly used in the heat transfer of fluid media (medium) thermal source, owing to not having slab construction, can not be used for the heat transfer or the heat radiation of solid thermal source.Another direction is tabular pulsating heat pipe.The basic structure of tabular pulsating heat pipe is the dull and stereotyped container that the two sides is all the plane, and internal placement has the pulsation conduit about capillary.This class heat pipe can be used for the heat transfer of fluid media (medium) thermal source, solid thermal source, applicable surface is wider than tubulose pulsating heat pipe, therefore also be convenient to industrialized mass production, board-like pulsating heat pipe is generally acknowledged it is present heat transfer property height by engineering circle, and a kind of pulsating heat pipe of tool application prospect.But the utility model the person think, there are two major defects in addition in this kind plank frame pulsating heat pipe, influences heat transfer property.Two major defects are respectively: the heat pipe surface is complete to be separate between plane, the inside heat pipe conduit, sealing.For the heat pipe surface is the situation on plane entirely, when air and heat pipe heat exchanging, because the heat pipe wall is the plane entirely, then air will skim over flat board fast, air and interplanar will form thicker thermal boundary layer, increase the heat exchange thermal resistance, the heat exchange of unfavorable air, thereby, make its heat exchange efficiency not perform to maximum.Separate between the inner conduit of opposite heat tube, as to seal situation, when then heat pipe was worked, independent conduit internal working medium will be only by its corresponding thermodynamic state variation, certain vapour, the liquid plug change at random of occurrence frequency under capillarity, the transmission of realization heat; After, working medium type certain when the conduit equivalent diameter determined, vapour, liquid plug change frequency were certain, therefore, can't by increase vapour, liquid plug change frequency improve the Heat Transfer of Heat Pipe on Heat Pipe performance.So do not reach the purpose of augmentation of heat transfer.
Chinese patent 200820054984 has proposed a kind of pulsating heat pipe formula air-conditioning exhaust system waste-heat recovery device.This device core component promptly is a kind of pulsating heat pipe element, and this pulsating heat pipe is to be bent into plane snakelike tube bank by the capillary metal tube to form.Though be pulsating heat pipe, it is few than flat-plate heat pipe to understand its heat exchange area easily, and inside heat pipe does not have transversal flow yet, and the thin easy deformation of coiled pipe causes the adopting heat pipes for heat transfer performance still not ideal enough, installs and uses also inconvenient.Chinese patent 200710304125 has proposed a kind of heat energy reclaiming equipment.This device core component is so-called pulsating heat pipe module, and this module is still and a kind ofly is bent into plane snakelike tube bank by the capillary metal tube in fact.The deficiency that has above-mentioned existence equally.
The electronic device cooling flat-plate heat pipe that Chinese patent 200810119311 proposes, its operation principle is that non-pulsation is conducted heat.Heat pipe framework and support member adopt integral braze-welded, and separate between the passage, sealing does not produce interchannel augmentation of heat transfer effect, and integral braze-weldedly will increase whole metal thickness and cause the thermal resistance increase.The tabular heat pipe that Chinese patent 200520011723 proposes, its operation principle are that non-pulsation is conducted heat.The heat pipe passage is square in addition, does not have sharp-pointed acute angle, the passage capillarity a little less than.Chinese patent 201010170205 proposes a kind of sintered flat plate heat pipe, and its passage is by filling metal powder sintered formation.This kind method can increase the thickness of whole housing, increases thermal resistance, and powder be difficult to fill closely knit evenly, also separate between the passage, sealing, can't by increase vapour, liquid plug change frequency improve the Heat Transfer of Heat Pipe on Heat Pipe performance.The flat-plate heat pipe that Chinese patent 200920246791 proposes, its passage are also separate between garden type, the passage, sealing.Then a little less than self capillarity, increase capillarity as desire needs process microflute, complex process to circle in circular channel.Also separate between the passage, sealing can't improve the Heat Transfer of Heat Pipe on Heat Pipe performance by increase vapour, liquid plug change frequency.
Technological document from above-mentioned open report, existing technology or patent are owing to the working mechanism that is adopted limits, or be subjected to structural limitations own, it is better that its heat transfer property does not all reach as yet, the needs that the Air conditioner air exchange energy that can not well meet the demands more and more harsh reclaims and cooling electronic component cools off.
Technical characterstic based on pulsating heat pipe, in conjunction with the application present situation of Air conditioner air exchange energy recovery with cooling electronic component, the utility model proposes a kind of board-like pulsating heat pipe of single face wave that is applicable to recovery of Air conditioner air exchange energy and cooling electronic component, a kind of novel, efficient, practical in the hope of forming, be suitable for the heat exchange elements of recovery of Air conditioner air exchange energy and cooling electronic component, also the progress and development for association area science and technology provides strong help and support.
