Description
Technical field
The present invention is particularly flowed to form a kind of magnetic force heat circulating system of a heat radiation circulation about a kind of magnetic particle that utilizes magnetic force to order about in the fluid about a kind of design of the circulatory system.
Background technology
Because in recent years, incident relatively behind the electronic product microminiaturization is to assembly, influence that system brought.Significantly increase but chip area but increases under the little situation at original chip functions, make and in like this confined space, need hold the more used heat of multiple transistor and sharp increase, promptly become the association area engineering staff and challenge greatly.And expected, it is powerful that the function of following various chipsets is seen more, and the compositing chip of each chipset is many more, and then the heat dissipation problem in the operation process will be a major challenge.
Therefore no matter be personal computer or notebook computer, the puzzlement of heat dissipation problem is all arranged in the use, be equipped with radiator fan although computer-internal is all built, but, usefulness is waited to improve, and adds the computer of fan, and weight increases, also consumes energy.When speed is more and more faster, except price is also more cheap, relatively also produce quite high used heat.No matter be which kind of processor, carrying out heat radiation work has been one of indispensable essential condition, otherwise gently then unstable, the system of computer work as machine, heavy then central processing unit (CPU) burns.
Notebook computer one to brag about conveniently, portability, but also in order to meet requirement easy to carry, notebook computer must be compact, makes the boundary that it reaches in light weight, volume is little.Mini notebook computer etc. for example.Just because so, so the inner space of notebook computer is always limited.The assembly of the power consumption of general notebook computer should be a central processing unit, and it is fast more to handle frequency, the central processing unit that operational effectiveness is high more, and power consumption and caloric value are also high more, and the electricity ratio low order processor that is consumed during work is higher, and the used heat of generation is also more.
Existing heat dissipation technology includes embedded fan and system fan, owing to the requirement to computer hardware inside usage space, comprises that in recent years the relevant heat dissipation technology of heat pipe is also constantly in renewal.Consult shown in Figure 1ly, it shows the sketch map of existing heat circulating system, and 10 of the heat pipes of heat circulating system 100 are equipped with liquid as a closed tubular vessel in the container.Wherein one of heat pipe 10 end connects heat-conducting unit 11, and heat-conducting unit system is incorporated into chipset 12.
The used heat that is produced when chipset 12 is transferred to heat pipe 10 via heat-conducting unit 11, makes the heated liquid in the pipe, and the liquid that is heated is done heat exchange through tube wall in heat-sink unit 13 at the other end of pipe via flowing.The advantage of existing heat pipe has advantages such as not power consumption, noiselessness, life-span length.The heat pipe technology of renewal then adopts the technical approach of exhaust fan and heat pipe, promptly when power demand is low, adopts the radiating mode of heat pipe passive type, when running power exceeds a certain limit, just opens fan and dispels the heat with active forced convertion pattern.
Yet, use the heat radiation of embedded fan or system fan, not only power consumption and be prone to produce noise, especially for the limited notebook computer in inner space, the radiating effect of small-sized fans is unsatisfactory.For the technology of heat pipe now; It is bad to exist a problem to be the thermal cycle effect; Reason is that the dynamical system of thermal cycle provides by the conversion between gaseous state and liquid two attitudes, and the conversion that form between these two attitudes just must need the appropriate environments temperature, so prior art is done cooling at colling end with radiating fin or fan; Let gas can condense into liquid, reach radiating effect.If it only is to lead casing that colling end does not have that radiating fin or fan initiatively lower the temperature; Out of question at the beginning, if but will increase to heat balance shell joint on opportunity contact temperature, and can't gas be condensed; Radiating effect reduces; Simultaneously also many because of the gas quantitative change, the internal pressure rising causes the boiling point of liquid in pipe also and then to rise, for example methyl alcohol or water.Cause evaporation and all approaching failure of condensing, the thermal cycle deleterious, the relative capacity of heat transmission also descends.
Summary of the invention
In view of the above problems, the invention provides a kind of magnetic force heat circulating system, be emitted to outside the pipe via tube fluid as the power resources of heat circulating system and then with the heat that thermal source sends with magnetomechanical effects, to reach the effect of heat radiation.
For achieving the above object, the present invention has adopted following technological means: a kind of magnetic force heat circulating system comprises a fluid pipeline, one first coil, one second coil.Fluid circuit is communicated with a heat-conducting unit, and heat-conducting unit conducts to fluid circuit in order to the heat energy that a pyrotoxin is produced.Wherein, the inner formation one of fluid circuit is filled with the runner of fluid, and in fluid, contains several magnetic particles.Moreover first coil is predetermined around apart from being surrounded on fluid circuit with one, and the second coil winding predetermined between distance through first coil, and likewise is surrounded on fluid circuit.
Native system more includes a power supply unit, one first switch element, a second switch unit; Controller sends one respectively and controls signal to first switch element and second switch unit; Be supplied to the electric current of first coil and second coil in order to the adjustment power supply unit; Make first coil and second coil produce an electric current time-varying field respectively, wherein the electric current time-varying field more makes first coil and second coil produce different field of magnetic forece respectively, forms the field of magnetic forece gradient of several continuous sections with the runner in fluid circuit; The field of magnetic forece gradient makes magnetic particle receive a magneticaction and orders about fluid and flow, and then makes the heat energy of heat-conducting unit give dissipation.
Compared to prior art; The invention provides a kind of magnetic force heat circulating system; By the liquid of high heat-conduction coefficient carrier as heat radiation; The existing fan of contrast is by the air thermal convection but the air heat conduction efficiency is very low, the shortcoming that causes heat-sinking capability to be restricted, and the present invention has the advantage of radiating efficiency height.Moreover; In the comparison prior art; The heat pipe circulation power is that the conversion between gaseous state and liquid two attitudes provides; And the appropriate environments temperature just can cause normal circulation, and the present invention has the technological means of the liquid circulation that initiatively causes high heat-conduction coefficient by the field of magnetic forece gradient of electric current time-varying field generation, can improve the shortcoming of passive type circulation in the existing heat circulating system.In addition, the volume of heat-conducting system of the present invention is little, has advantage such as do not take up space, system consumption power is low for the use in computer-internal space.
The specific embodiment that the present invention adopted will be done further explanation by following embodiment and accompanying drawing.
