Description
Technical field
The present invention relates to a kind of electromagnetic pump, particularly a kind of inside has the electromagnetic pump that is used to drive the liquid metals motion of slide block, is used in the actuating force that significantly promotes electromagnetic pump under the prerequisite that does not increase the liquid metals consumption.
Background technology
In recent years, along with the develop rapidly of high-end computer chip, photoelectric device technology, the thermal boundary problem is on the rise, and has become the bottleneck that the restriction chip technology further develops.So far, Chang Yong radiating mode mainly comprises: three kinds of air-cooled, water-cooled and heat pipe heat radiations.Wherein, the conventional air-cooled radiating requirements that has been difficult to satisfy high-performance photoelectricity equipment, water-cooled and heat pipe heat radiation can also satisfy current heat radiation load to a certain extent.But the shortcoming of water-cooled is that the thermal conductivity of water is low, volatile, boiling point is low; The shortcoming of heat pipe heat radiation is that excessive heat load can cause heat pipe failure, thereby causes chip overheating.
For this reason, (Liu Jing, Monday is glad, a kind of radiating device of chip radiation, grant number: 02257291.0) proposed with low-melting-point metal or its alloy computer chip heat dissipating method as cooled flow working medium for patent.This is the new concept of introducing first in the computer craze management domain.Because having thermal conductivity far above water, air and many nonmetal mediums, liquid metals (is about 60 times of water as being in liquid gallium thermal conductivity near the room temperature, exceed more than 1000 times of air), and has flowability, thereby can realize rapidly and efficiently heat transportation ability, this is a substantial expansion for existing radiating mode.This low-melting-point liquid metal has solved the heat radiation difficult problem that high density can flow to greatest extent with the heat transfer potential far above traditional flow working medium.Particularly, owing to adopted liquid metals, radiator can do very for a short time and be easy to drive, can realize whole integrated minitype radiator thus by the lower electromagnetic pump of power consumption.
The proposition of liquid metals heat dissipation technology, broken through existing enhance heat idea, with heat transfer potential, solved the heat radiation difficult problem of excessive heat current density chip to greatest extent far above traditional flow working medium (as air, water, organic solution or greater functionality fluid).In this method, fluid velocity is high more, and the ability that then transports heat is strong more.As everyone knows, in driving the electromagnetic pump that metal liquid flows, electromagnetic field is applied to actuating force F on the liquid metals and can be expressed as F=BIL (wherein, B is the magnetic field that permanent magnet produces, I is the size of current that flows through liquid metals in the pump chamber, and L is the width of liquid metals runner in the pump chamber); Formula will promote the actuating force of electromagnetic field to metal fluid as can be seen thus, except adopting strong as far as possible permanent magnet, needs to increase electric current, and design brings big difficulty but the increase meeting of electric current is to power supply, has also increased energy consumption.Therefore, if the metal fluid width that can enlarge in the pump chamber runner is the size of L, then can be issued to bigger actuating force in downfield, little current conditions.But, increase liquid metals runner width, can increase the consumption of liquid metals undoubtedly, and near the metal of fusing point room temperature is generally comparatively expensive, thereby makes that the overall making cost of radiator is higher.
Consider above-mentioned factor, the invention provides the electromagnetic pump that is used to drive liquid metals that a kind of inside has the metal slide block, can under the prerequisite that does not increase the liquid metals consumption, promote the actuating force of electromagnetic pump.Its principle is in pump chamber the nonmetal slide block instead of part liquid metals that adopts lower metal of common price or surface-coated that metal film is arranged, thereby reduces cost; And this metal slide block can serve as the driven object of electromagnetic field with the liquid metals that flows through on every side, can expand L greatly by the introducing of metal slide block thus, thereby promotes the driving force to metal fluid under the situation that does not increase the liquid metals consumption.
