Description

FIELD OF INVENTION

This invention is related to heat exchange technology and method, specifically, an integrated heat pipe and its heat exchange method.

BACKGROUND OF THE INVENTION

The development of LSI, mainframe computer and electrical and electronic technologies has imposed higher requirements on the heat elimination of electronic elements and components. For example, the integration level of CPU chips of computers has risen by nearly 20,000 folds just within 30 years with its consumption power rising up to a few dozen watts from its initial a few watts and with the resulting heat flux being up to 100 W/cm²in some cases. The working reliability and life of computer is closely related to its working temperature and the required maximum temperature (internal) of chips ≦130° C. and the required surface temperature ≦80° C. However, its working reliability will decrease by 3.8% whenever the temperature of chip rises by 1° C., and its life will increase by 50% whenever the temperature of chip decreases by 10%. High speed and high integration level imposes very high requirement on the uniformity of the temperature of chips. Therefore, heat elimination has become a major problem that has to be resolved in the course of research and development of electronic products and it is directly related to the property, reliability and cost of electronic products.
Initially, there were several heat elimination technologies for chips, such as heat elimination fan, heat elimination plate, pre-made heat elimination holes, keyboard convection heat elimination, water cooling heat elimination, etc. Though their cost was low, their heat eliminating effect was not so good and their reliability was low, therefore, they were not able to meet the requirement of the development of computer.
The State Laboratory of Sandia in the USA first applied heat pipe technology in the heat elimination of computer chips, which produced fairly good heat elimination effect.
Heat pipe technology is a highly effective heat transfer element and highly effective heat transfer technology, which transfers heat by the phase change process, that is, to fill a small amount of liquid medium into the enclosed vacuum chamber of a tubular article, where a liquid medium is used to absorb heat, vaporizes, condenses and eliminates heat. Heat pipe heat exchanger is so constructed that the heat absorption end and heat elimination end of several heat pipe elements are partitioned and the heat absorption end and heat elimination end are surrounded with articles to form two shaped cavities, heat absorption and heat elimination, with hot fluid flowing through the heat absorption chamber and the cold fluid flowing through the heat elimination chamber, thus heat being transferred to the cold fluid via heat pipe and the phase change of the heat pipe medium. The structural characteristic of heat pipe is that the inner chamber of a flexible tubular article is vacuumed and filled with a small amount of liquid medium and the inner chamber of the pipe is just big enough for a liquid absorption cartridge that ensures liquid reflux. A single heat pipe can be used as heat exchanger, but it is more often that the heat exchangers composed of several heat pipe elements are used at the same time.
However, the current heat pipe technology of the heat elimination of plane heat sources, such as computer chips and other electrical and electronic elements and components is mostly of studded heat pipe type. That is to make notch in the metal plate of fine thermal conductivity, inlay the heat absorption end of heat pipe in the notch, put the heat elimination end at a ventilated place and the metal plate is placed horizontally above the heating element. In order to ensure that the heat source plane is in full contact with the metal plane and electrically insulated, a heat conducting insulation plate coated with heat conducting silicone is placed between them. Heat is transferred via heat conducting silicone, heat conducting insulating plate from the heat source to the metal plate, then to the heat pipe, where as a result of phase change heat is transferred from heat absorption end to the condensation end, and the heat absorbed at the condensation end is transferred through the shell of the heat pipe to another layer of silicone, then to the aluminum fin type radiator. The heat accumulated in the fin radiator is carried away by forced cold wind to accomplish the purpose of reducing the temperature of the heat source ultimately. This inlaying method does not produce very good heat elimination effect as the contact thermal resistance of the element connected with interface in the course of heat transfer is so big that the heat pipe cannot play the role of high efficiency heat transfer and the heat eliminating effect is not so good. In addition, through by welding the heat absorption end of one or several heat pipes on the metal plate and installing a number of fin groups to support heat elimination at the heat elimination end of heat pipe, the contact thermal resistance of the interface can be reduced, the medium of the heat pipe can not be in full contact with the heat source and can not produce very good heat transfer effect.
In the metal foundry Industry, in order to ensure that the alloy melt solidifies immediately in the casting mould and cools down the mould within shortest time to increase the production efficiency of casting moulds, some people insert the heat absorption ends of many heat pipes into the main body of the hard mould to take advantage of the inherent axial heat transfer characteristic of conventional heat pipe in hard mould foundry and in ejection molding and insert the heat elimination end of heat pipe into water cooling pipe so as to level the temperature gradient in the hard mould by heat pipe and to conspicuously improve the heat transfer efficiency of the casting mould without increasing water consumption. What merits attention is the application of heat pipe technology in foundry Industry includes the newest continuous casting and continuous rolling processes, such as wheel rolling and wheel casting and continuous crystallizing that require heat exchanging. Up to now, no structure other than the conventional heat pipe and any new heat transfer mode have been found. However, because of the interface thermal resistance between the casting mould and the wall of heat pipe and the limitations of the structure it is impossible for the original structure to meet the even higher cooling speed requirement of alloy including fast solidifying alloy on the mould and it is more so of certain special and higher requirement.
The fast solidifying metal technology is to fix metal molecules on higher energy level. Since Duwez invented the fast solidifying technology in 1960, the technology has been improved and systemized continuously and commercialized gradually. Because of its high dynamic property and fine physical and chemical property the fast solidifying metals have attracted the attention of the materials scientific workers throughout the world, who have put much manpower, material and funds in the research. As a result of the development over the last three decades the fast solidification technology and its research on metals have become one of the important branches of materials science and engineering. As the fast solidification technology is to increase the super-cooling extent and speed of solidification mainly by increasing solidification speed, the solidification speed is very important for the formation and property of the fast solidifying material.
At present, there are dozens of fast solidification processes and equipment for production of fast solidifying materials, mainly in three categories of mould cooling technology, atomization technology and surface melting and sedimentation technology. According to the basic principle of fast solidification for melt dispersion and thermal resistance reduction the existing production unit includes rotating or fixed cold mould (or base), mostly made from metals of fine thermal conductivity. Its heat exchange method is to build a cooling liquid passage in fabrication of the equipment base, which is designed to carry away swiftly the heat absorbed by the base to accomplish the fast cooling purpose of fast solidifying material. Because of the limitations of the traditional heat transfer mode and the structure of the base the contact area between base and cooling liquid is small (normally, the area of the heat absorption end is always bigger that that of the heat elimination end) and contact thermal resistance is big, it is difficult for the cooling liquid to carry away the large amount of heat emitted by the melt during the solidification process instantly. Therefore, it is very difficult to improve and balance the distribution of temperature field so as to further increase the heat transfer speed during the solidification process. Moreover, as the temperature at the heat balance spot of the base is fairly high during operation, the capacity of the production unit declines, its life gets shorter, its efficiency gets lower and the quality deteriorates. Up to now there is no report about any application of heat pipe technology in the field of fast solidification technology.
Hot fluid ejecting nozzles are widely applied in engineering technology, particularly, plasma welding cutting torch, plasma spray coating nozzle, nozzle of electron beam welding torch, nozzle of large power arc welding torch, etc. As the high temperature heat flux flows through nozzle for such a long time during operation that the nozzle is easily damaged, people tend to manufacture nozzles with metals of fine thermal conductivity and some even cool nozzles with water. Notwithstanding all this, the effect is not so good and the life does not get any longer and the cooling water leakage may damage the electrical insulation of the equipment greatly reducing the reliability of the equipment. Although some people use heat pipe technology in nozzles, the high efficiency heat transfer characteristic of heat pipe can not be displayed because their technical design fails to greatly improve the heat elimination area of nozzle and the geometric dimensions of nozzle are small. Therefore, the existing technology is still unable to meet the requirement of the engineering technology and should be further improved.
Heat exchanger, including that for heat exchange between fluid media is the most conventional basic equipment used in various Industrial sectors of the state economy. People have never stopped in trying to improve the function of heat exchanger to increase the heat transfer efficiency of heat exchanger by various technologies, methods and means over hundreds of years. The heat pipe phase change heat transfer technology, including the use of high heat conductivity medium to transfer heat, is an effective try. The high thermal conductivity, big heat elimination area and fairly low production cost of heat pipe heat exchanger is well applied in residual heat recovery in the field of heat exchanger. Nevertheless, the branch like distribution of the heat pipe of the traditional heat pipe heat exchanger and its square box structure is apt to fouling on heat elimination surface and dead corner and whirlpool of fluid flow thus affecting the normal heat exchange and application life of heat exchanger. The single structure and huge volume of the traditional heat exchanger is one of the limiting factors. Up to now there is no report about any application of integrated heat pipe technology in the field of heat exchanger.
Large electric motor, generator and engine are the power source of the modern Industry, the mainstay for the existence of modern technology and the basic equipment of the state economy. Their common structural characteristic is that they all have a turning shaft-rotor that requires heat elimination any time. If the heat including that emitted inside the rotor cannot be eliminated, overheating might happen reducing the power, abating the insulation and damaging electrical and mechanical equipment, or even leading to the loss of working capacity of equipment. Generally speaking, for every degree of temperature rises above the upper limit of the motor, its life span is reduced by half. In order to eliminate heat from rotor the large capacity motor and generator are normally cooled with the gas in enclosed re-circulation, or by pipe ventilation, independent fan type cooling or by having hollow copper winding of rotor for cooling water flowing through the hollow copper winding, shaft and sealed water jacket to carry away the heat. Some people apply the heat pipe phase change heat transfer technology to improve the heat elimination of motor rotor in this manner that they hollow out the shaft of the motor so as to form a somewhat biased empty chamber, which extends through the heat absorption end and heat elimination end of rotor and is vacuumed and filled with a small amount of liquid medium. The medium absorbs heat and vaporizes at the heat absorption end and emits heat and condenses into liquid at the heat elimination end. The reflux liquid flows back to the heat absorption end over the slope under the action of a centrifugal force. The heat carried by the medium at the heat elimination end is carried away by the cold air blowing out of the fan and the internal heat in the rotor is ultimately eliminated thus forming a reciprocating heat recycle. The rotating heat pipe technology can produce fairly good effect in improving the heat elimination of motor rotor. However, the above-mentioned methods have many shortcomings, such as inferior heat elimination and high production cost and still they have a common shortcoming, that is, heat elimination area is small and the heat elimination capacity is intrinsically inadequate. How to improve the heat elimination capacity of motor rotor and to enhance the capacity and reliability of the above-mentioned power machines has been a subject that the scientists and engineers have to confront for a long time.
As described above, the existing heat pipe, heat pipe heat exchanger and heat pipe heat exchange technology, initially applied in home appliances, have found more and more applications in high tech spheres such as aviation and space Industries as a result of their development over last 50 years or so because of simple structure, reliability, high heat thermal conductivity and easy realization and they are being used in more and more areas. Some new heat pipe structures and new heat transfer mechanisms came into being over recent years, but up to now the method for increasing the heat elimination area of heat pipe of heat exchange technology is mostly to increase the absolute length of the heat elimination end of heat pipe, install auxiliary heat elimination ribbed plates and increase the number of heat pipes; the structure of heat pipe heat exchanger is still single; the structure of the heat absorption end of heat pipe and heat pipe radiator is still short of any variation. All these have greatly limited the application and popularization of heat pipe and heat pipe technology. Particularly, as to how to reduce thermal resistance of contact heat source apart from the heat flux to increase heat transfer efficiency, it is difficult for the existing heat pipe heat exchange technology to display its merit fully because of its unique structure. For the heat elimination for a narrow space, special geometric shape and large heat flux density and the heat elimination for the large heat flux density during intermittent interval and the limited cold source conditions, it is imperative to improve the existing heat pipe technology.

When liquid medium is used in the integrated heat pipe, the surface of the heat absorption chamber connected with vacuum chamber can has such liquid absorbing cartridge structures as groove or sintered metal powder or other effective liquid absorbing cartridge structure. A liquid medium accumulation basin can be placed under the liquid absorbing cartridge.

When a liquid medium is used, a liquid absorbing cartridge structure of heat pipe can be placed some where in the enclosed chamber closest to the heat-absorbing surface.
According to this method, when the heat absorption end of heat pipe is an end surface or part of the end surface vertical to the axial line of heat pipe, the shaped surface of its heat absorption end can be so made as to correspond, tally and closely match with the outline surface of heat source. It can be made smooth, flat and straight; smooth and raised; smooth and sunken; it can be made according to the outline curved surface of contact heat source, or inlaid and covered and fully and closely matched.
This method is so designed that when the heat absorption end of heat pipe is one or more than one groups of heat absorption cavities that run through shell and enclosed chamber, the heat absorption chamber structure can be that running through the two opposite ends of shell, or that running through two neighboring ends of shell or that running through the same end of shell. The cross section of its heat absorption chamber can be circular, rectangular, polygon, dentiform or other geometric shape. The vertical section of its heat absorption chamber can be of a slope.
This method includes that the heat absorption end of heat pipe is so made that the outline surface of its cross section is circular and covers the revolving shell of enclosed chamber. The outline surface of its vertical section is rectangular, drum-shaped or other revolving shape that meets the requirement of heat source.

A heat exchange method with integrated heat pipe. This method uses the contact heat source on the surface of the heat absorption end of heat pipe shell to absorb heat and transfer heat to the same heat transfer medium in the same enclosed chamber via the wall surface of the heat absorption end of shell to enable the heat transfer medium to absorb heat or to absorb the heat absorbed in fast dispersion of vaporization, and use the heat carrier placed outside enclosed chamber or inside it or outside and inside it as heat elimination end, and the heat absorbed by heat transfer medium is contained or transferred; this method uses the low temperature fluid in the thin-wall fluid passage placed outside enclosed chamber or inside it or outside and inside it to transfer the heat absorbed by heat transfer medium. This method uses the thermal container placed outside enclosed chamber or inside it or outside and inside it to hold the heat absorbed by heat transfer medium. This method uses the heat transfer medium of heat pipe placed somewhere in enclosed chamber closest to the heat absorption surface and uses heat transfer medium to carry away heat to the place where heat carrier is closest to the heat elimination surface to reduce thermal resistance, improve heat transfer conditions and increase thermal conductivity.
A liquid medium involving method of heat exchange with rotating integrated heat pipe. When the hot pipe is turning at a high speed, this method uses the shell of circular cross section of heat pipe as heat absorption end surface, which absorbs heat while turning at a high speed, and transfers heat via the wall surface of heat absorption end of shell to the same heat medium in the same enclosed chamber that is swung on the surface of inner wall of heat absorption end. The heat transfer medium absorbs heat and vaporizes quickly, and the enclosed chamber is filled with saturated steam, which is quickly condensed on the surface of thin-wall fluid passage as soon as it meets the low temperature fluid. The hidden vaporization heat carried over is released and the thin-wall fluid passage transfers the hidden vaporization heat to the cold fluid outside the enclosed chamber of thin-wall fluid passage, and the heat absorbed by heat pipe is carried away by cold fluid ultimately. The mass of the liquid medium condensed on the surface of thin-wall fluid passage increases quickly under the centrifugal force and the liquid medium is swung on the surface of the inner wall of heat absorption end again thus starting a new round of heat transfer process, which repeats again and again. This method is of a large heat elimination area, and by taking advantage of phase change an even heat transfer can be carried out at the same temperature throughout the whole heat elimination area. The centrifugal force of the turning heat pipe ensures that the liquid medium flows towards the heat absorption end and the interface thermal resistance in the course of phase change heat transfer can be reduced by a biggest margin so that an optimum heat transfer effect is obtained.
When heat pipe is turning at a lower speed, this method uses the shell of circular cross section of heat pipe as heat absorption end surface, which contacts the heat source at a low turning speed to absorb heat, which is transferred to the same heat transfer medium in the same enclosed chamber that is adhered on the inner wall surface of heat absorption end under the adhesive action of liquid medium and is in the liquid absorbing cartridge. The heat transfer medium absorbs heat and vaporizes quickly, and the saturated steam filling the enclosed chamber condenses quickly on the surface of thin-wall fluid passage as soon as it meets the low temperature fluid in the thin-wall passage, and the hidden vaporization heat carried over is released, and the thin-wall fluid passage transfers the hidden vaporization heat to the cold fluid outside the enclosed chamber of thin-wall fluid passage, and the heat absorbed by heat pipe is ultimately carried away by the cold fluid. The mass of the liquid medium condensed on the surface of thin-wall fluid passage increases quickly under the weight action, and it then returns to the lowest part of the enclosed chamber of heat pipe. The liquid medium enters the liquid absorbing cartridge of heat pipe under the action of capillary force of liquid absorbing cartridge of heat pipe, and is back again to the position in contact with heat source, thus starting a new round of heat transfer process, which repeats again and again. This method is of large heat elimination area and uses phase change to carry out even heat transfer at the same temperature throughout the heat transfer area, and the capillary force of the liquid absorbing cartridge of heat pipe and the adhesive force of the heat pipe medium ensure that liquid medium flows toward the heat absorption end and ideal heat transfer effect can be obtained similarly.

As the condensed liquid medium on the surface of the thin-wall liquid passage accumulates, it returns again to the lowest position of the enclosed chamber 7-2 of the heat pipe under its own gravity, the liquid medium 7-3 will run into the heat pipe liquid absorption cartridge under the capillary force and it is brought again to the position where it can contact the heat sources, thus a new round heat transfer begins, and in this way, it repeats continuously. This method has large heat radiating surface, uses the phase change to realize even heat transfer under the isothermal surface conditions.

As the condensed liquid medium on the surface of the thin-wall liquid passage accumulates, it returns again to the lowest position of the enclosed shell 8-2 of the heat pipe under its own gravity, the liquid medium 8-3 will run into the liquid absorption cartridge 8-5 of the heat pipe under the capillary force and it is brought again to the position where it can contact the heat sources, thus a new round heat transfer begins, and in this way, it repeats continuously. This method has large heat radiating surface, uses the phase change to realize even heat transfer under the isothermal surface conditions.
