Abstract
The present invention relates to a radiator which uses magnetized heat conduction liquid. The present invention at least comprises a base, a magnetic field generator and a plurality of heat conduction fin-shaped objects, wherein the base comprises a circulating pipe for accommodating and magnetizing the heat conduction liquid; the magnetic field generator is positioned in the base and is used for generating a magnetic field; a plurality of heat conduction fin-shaped objects are formed on the base and formed around the circulating pipe; the magnetic field generated by the magnetic field generator has the function of making the magnetized heat conduction liquid flow in order to reach the goal of heat radiation.
Description
The relevant a kind of radiator of the present invention, particularly relevant a kind of radiator that uses magnetized heat-conducting liquid.
Continuous lifting along with electronic installation usefulness, heat abstractor or system have become indispensable outfit part in the existing electronic installation, because if the heat that electronic installation produced is not in addition suitably dissipation, light usefulness variation then, heavy then can cause burning of electronic installation.Heat abstractor is even more important for micromodule (for example integrated circuit), because along with the increase of aggregation degree and the progress of encapsulation technology, make the area of integrated circuit constantly dwindle, the heat that the while per unit area is accumulated also relatively can be higher.
In the prior art, radiator generally is to dispel the heat by flowing of air, for example the fin with an aluminum is attached on the micromodule, or on described fin, fold again and establish a fan, make the heat of described micromodule conduct to described fin earlier and brush described fin by the running of fan again, with the radiating and cooling effect of auxiliary heat dissipation sheet.Yet, for now or for following more at a high speed the micromodule, it is not enough that the radiating efficiency of prior art has been disliked.Because air is not best heat radiation material, other material for example liquid such as water all has the specific heat higher than air, so radiating effect can more only use the air heat radiation better.
Therefore, in the prior art, the cooling system that uses heat-conducting liquid to dispel the heat is arranged also, they can be described as " liquid cooling system ".Yet, but existing liquid cooling system must arrange in pairs or groups one for example the flow device of pump heat-conducting liquid is flowed.Like this, need heat abstractor to add that volume and pipeline complexity behind the pump will heighten.And the volume of the existing cooling system of this kind will be much larger than the need heat abstractor.
Therefore, the purpose of this invention is to provide a kind of simplify pipeline and with the approaching radiator of volume of the device of need heat radiations.
The radiator of use magnetized heat-conducting liquid of the present invention is characterized in, which comprises at least: a base has a spatial accommodation, in order to hold a magnetized heat-conducting liquid; One magnetic field generation device is arranged in described base, in order to produce magnetic field; And several heat conduction fins, be formed on the described base.
Radiator of the present invention places one to need on the device of heat radiation, for example a microprocessor or a central processing unit.Wherein said base has a circulation line, and described circulation line spreads all over whole base as much as possible.One heat-conducting fluid is housed, for example one in the described circulation line " magnetized heat-conducting liquid ".Described " magnetized heat-conducting liquid " but be meant to have magnetic and heat-conducting fluid, for example in heat-conducting fluid, mix metal particle, so can make described heat-conducting fluid become one " magnetized heat-conducting liquid ".When applying a magnetic field (power), described magnetized heat-conducting liquid will flow because of magnetic.It should be noted that the magnetized heat-conducting liquid in described circulation line do not fill fully, but reserve a cushion space.Its purpose is to reserve the required volume of magnetized heat-conducting liquid vaporization back expansion.
Unlike the prior art be that the flow device that the present invention need not external for example pump flows heat-conducting liquid.Described base also has an agitating device, be surrounded on described circulation line around, or be adjacent to described circulation line.Described agitating device is a coil for example, and is external to a power supply unit (DC power supply or AC power supply), and when power supply unit applied a voltage on the described coil, described coil can produce magnetic field.This magnetic field can make described magnetized heat-conducting liquid flow in described circulation line and take away heat and reach the purpose of heat radiation.
Also have a heat conduction fin on the described base, several sheet metals that are arranged side by side for example are in order to increase area that radiator contacts with outside air with the increase radiating efficiency.In addition, the alternative sealing device that forms is between described base and described heat conduction fin, further to avoid the spill and leakage of described magnetized heat-conducting liquid.
The present invention uses magnetized heat-conducting liquid to dispel the heat, thus the present invention need not to arrange in pairs or groups one for example the flow device of pump heat-conducting liquid is flowed, therefore can simplify pipeline and reduced volume.In other words, the volume of heat abstractor of the present invention can be very near the device that needs heat radiation.
Be elaborated below in conjunction with the radiator of accompanying drawing, so that clearer understanding purpose of the present invention, characteristics and advantage to a preferred embodiment of the present invention.
Fig. 1 is the schematic diagram of radiator of the use magnetized heat-conducting liquid of a preferred embodiment of the present invention.
Still see also Fig. 1, described base 200 also has an agitating device (not shown), be surrounded on described circulation line 210 around, or be adjacent to described circulation line 210.A described agitating device for example coil is external to a power supply unit (DC power supply or AC power supply), and when power supply unit applied a voltage on the described coil, described coil can produce magnetic field.This magnetic field can make described magnetized heat-conducting liquid flow in described circulation line 210 and take away heat and reach the purpose of heat radiation.
Still see also Fig. 1, also have a heat conduction fin 500 on the described base 200, several sheet metals that are arranged side by side for example are in order to increase area that radiator 100 contacts with outside air with the increase radiating efficiency.In addition, the alternative sealing device 600 that forms is between described base 200 and described heat conduction fin 500, further to avoid the spill and leakage of described magnetized heat-conducting liquid.Described sealing device 600 is an O type ring for example.
In sum, the present invention uses magnetized heat-conducting liquid to dispel the heat, thus the present invention need not to arrange in pairs or groups one for example the flow device of pump heat-conducting liquid is flowed, therefore can simplify pipeline and reduced volume.In other words, the volume of heat abstractor of the present invention can be very near the device that needs heat radiation.
The above is preferred embodiment of the present invention only, is not in order to limit claim of the present invention; All other do not break away from equivalence change or the equivalence replacement that disclosed spirit is finished, and they all should be included in the scope of patent protection of the present invention.
