Description
Technical field
The present invention relates to a kind of heat abstractor, and in particular to a kind of substrate cavity of bottom even radiating.
Background technology
Radiating mode refers to that the radiator distributes the major way of heat.In thermodynamics, radiating is exactly heat transfer, and
The transfer mode of heat mainly has three kinds：Heat transfer, thermal convection current and heat radiation.Material in itself or when material is contacted with material,
The transmission of energy is thus referred to as heat transfer, and this is a kind of most common thermaltransmission mode.Thermal convection current refers to that the fluid of flowing will
The thermaltransmission mode that the torrid zone is walked.Heat radiation refer to by ray radiation transmission heat, it is daily it is most common be exactly solar radiation.
These three radiating modes are not isolated, in daily heat transfer, and these three radiating modes are all to occur simultaneously, jointly
Work.In fact, any kind of radiator, which is substantially all, can use three of the above thermaltransmission mode simultaneously, simply stress
Point is different.The thermal capacitance of the radiating efficiency of radiator and the pyroconductivity of radiator material, radiator material and heat eliminating medium
And the relating to parameters such as effective area of dissipation of radiator., can be by radiator point according to the mode that heat is taken away from radiator
For active heat removal and passive radiating, the former commonly air-cooled radiator, and the latter it is common be exactly fin.Further subdivision
Radiating mode, can be divided into cold air-cooled, heat pipe, liquid, semiconductor refrigerating and compressor cooling etc..Wind-cooling heat dissipating is most common
, and it is very simple, exactly walk the heat that radiator is absorbed using fan belt.With price it is relatively low, install simple
The advantages of, but higher to condition depended, such as temperature rise and its heat dispersion will be greatly affected during overclocking.
Existing traditional radiator structure is radiated using substrate plus fin, and substrate passes through heat biography by contacting thermal source
The mode led passes to fin, and fin takes away heat according to the contact with air, but during the use in reality,
For big heat sink, it can be heated because of base plate bottom uneven, the heat for causing to be delivered on fin is uneven, this
Sample brings the harm of two aspects, first it is heated it is uneven the speed entirely radiated can be caused to reduce, second due to fin
With the integral structure of substrate, whole radiator replacing can be caused because local radiating transition fin aged deterioration.
The content of the invention
The technical problems to be solved by the invention are, because base plate bottom is heated uneven, to cause to be delivered on fin
Heat is uneven, it is therefore intended that provide a kind of substrate cavity of bottom even radiating, solve because base plate bottom be heated it is uneven,
Cause to be delivered to the problem of heat on fin is uneven.
The present invention is achieved through the following technical solutions：
It is aquifer, substrate-side in a kind of substrate cavity of bottom even radiating, including substrate and fin, the substrate
Face is set and sets water inlet, lower section delivery port above perforate face, the perforate face, and water inlet and delivery port are sealed by piston
Close；At least one agitating device is set in the aquifer, and the agitating device is connected with base plate bottom.Existing traditional dissipates
Heat structure is radiated using substrate plus fin, and substrate passes to fin by contacting thermal source by way of heat transfer, is dissipated
Backing takes away heat according to the contact with air, but during actual use, for big heat sink, can be because
It is heated for base plate bottom uneven, the heat for causing to be delivered on fin is uneven, so brings the harm of two aspects,
First it is heated it is uneven the speed entirely radiated can be caused to reduce, second due to fin and the integral structure of substrate, can be because
For local radiating transition fin aged deterioration, whole radiator can be caused to change, the technical problems to be solved by the invention are
Because base plate bottom is heated uneven, the heat for causing to be delivered on fin is uneven, it is therefore intended that provide a kind of bottom equal
The substrate cavity of even radiating, the present invention is directed big heat sink, what those skilled in the art generally considered is exactly to increase
The thickness of substrate, but the present invention does not consider to increase the thickness of substrate to improve heated uneven situation, because increase substrate
Thickness cost too expensive, the present invention taken substrate cavitation, internal liquid filling body, and the heat transfer speed of liquid is very
It is fast, and bottom increase agitating device, further ensure substrate internal water even heat situation, contrast increase substrate
Thickness, using liquid agitation so that fin thermally equivalent effect more, and cost is greatly reduced, although add opening
Etc. process, but middle cavity, the material of script is saved, the cost before such set of device contrast is very nearly the same.
The perforate face is flexibly connected with substrate.This is to open for convenience, takes out agitating device.
The agitating device quantity is 1, positioned at base plate bottom centre position.New preferred scheme is realized as this.
Closing battery is set in the agitating device, is snapped connection with base plate bottom, present this enclosed battery technology
It is highly developed, quotes this technology to the structure of the present invention to use.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of substrate cavity of bottom even radiating of the invention, cavity design, overall weight saving；
2nd, a kind of substrate cavity of bottom even radiating of the invention, takes substrate cavitation, internal liquid filling body, liquid
Heat transfer speed be very fast, and increase agitating device in bottom, further ensure that the heat of substrate internal water is equal
Even situation, the thickness of contrast increase substrate, using liquid agitation so that fin thermally equivalent effect more, and cost is significantly
Reduce；
3rd, a kind of substrate cavity of bottom even radiating of the invention, the heated heat dispersal situations of fin at top are identical, almost
Aging simultaneously, more calculates during replacing.
