Description

Liquid-cooling heat radiator
[technical field]
The present invention relates to a kind of heat abstractor, particularly about a kind of liquid-cooling heat radiator that is used for cooling electronic components.
[background technology]
Along with electronic technology constantly develops, electronic component running frequency and speed are also in continuous lifting.But the heat that high-frequency high-speed will make electronic component produce is more and more, and temperature is also more and more higher, and performance and stability when the electronic component operation in serious threat for guaranteeing the normal operation of electronic component energy, need effectively dispel the heat to electronic component.But existing simple metal heat abstractor more and more is difficult to satisfy the heat radiation needs of high-frequency high-speed electronic component, and for this reason, liquid cooling heat radiation system is adopted by industry gradually.
Existing liquid cooling heat radiation system comprises a reservoir, and this reservoir is surrounded by the base that contacts with heater element and loam cake two parts and forms, and cooling fluid is carried out heat exchange with this base in this reservoir, by the circulation of cooling fluid the heat of this base is taken away.Yet because the heat exchange area of cooling fluid and base is little, heat exchange is abundant inadequately, and therefore most of heat is accumulated on this base, influences radiating effect.
[summary of the invention]
The object of the present invention is to provide the respond well liquid-cooling heat radiator of a kind of heat exchange.
Technical scheme of the present invention is: a kind of liquid-cooling heat radiator, comprise a heat-absorbing block in order to the heat that absorbs heater element, be provided with a cavity that is used to store cooling fluid in this heat-absorbing block, this heat-absorbing block is provided with the feed liquor interface that communicates with this cavity respectively and goes out liquid interface, this feed liquor interface and this go out to be provided with fluid path between the liquid interface, this heat-absorbing block comprises a base that contacts with heater element and a loam cake that is positioned on this base, and this base top layer contacts with cooling fluid, and this top layer has loose structure.
Because the base top layer has loose structure in the liquid-cooling heat radiator of the present invention, has effectively increased the contact area of this base and cooling fluid, strengthen the heat exchange effect of cooling fluid in heat-absorbing block, therefore, radiating effect is good than prior art.
[description of drawings]
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the assembly drawing of liquid-cooling heat radiator of the present invention.
Fig. 2 is a liquid-cooling heat radiator heat-absorbing block stereogram of the present invention.
Fig. 3 is the cutaway view of liquid-cooling heat radiator of the present invention along III-III line among Fig. 2.
Fig. 4 is the schematic diagram of liquid-cooling heat radiator heat-absorbing block base of the present invention.
[embodiment]
Below in conjunction with accompanying drawing liquid-cooling heat radiator of the present invention is described in further detail.
See also Fig. 1, assembly drawing for liquid-cooling heat radiator of the present invention, this liquid-cooling heat radiator comprises a heat-absorbing block 10 and a pump housing 50 that closely contacts with heat-generating electronic elements (figure do not show), this pump housing 50 links to each other with this heat-absorbing block 10 by a drain pipe 100 and a feed tube 200, thereby forms a fluid path.This heat-absorbing block 10 is used to absorb the heat that heat-generating electronic elements produces, be provided with an enclosure space (will introduce in detail) that is used for storing cooling fluid in it at Fig. 2, this enclosure space, drain pipe 100, the pump housing 50 and feed tube 200 form a liquid circulation loop, under the driving of this pump housing 50, this cooling fluid direction along arrow indication among Fig. 1 in this circulation circuit flows, thereby the heat that continuously heat-absorbing block 10 is absorbed is taken away.Because cooling fluid has absorbed the heat of heat-absorbing block 10, the coolant temperature that flows out heat-absorbing block 10 raises, if the cooling fluid that allows temperature raise just enters next circulation through behind the natural cooling, radiating effect is obviously bad, therefore, liquid-cooling heat radiator of the present invention also establishes one in order to reduce the cooling device of coolant temperature, as most fin 30 in the appropriate location in above-mentioned liquid circulation loop, also can on fin 30, install fan (figure does not show) additional, improve radiating effect.
Clear in order to illustrate, the heat-absorbing block 10 among Fig. 1, fin 30 and the pump housing 50 are to disperse to be provided with, and are appreciated that ground, and said elements also can be incorporated into together, as the fin 30 and the pump housing 50 directly are installed on the heat-absorbing block 10, can save than large space like this.
See also Fig. 2 and Fig. 3, this heat-absorbing block 10 comprises that a base that contacts with heater element 11 and is positioned at the loam cake 12 on this base 11, form the cavity 14 that is used to store cooling fluid of a sealing between this loam cake 12 and the base 11, cooling fluid is carried out heat exchange with heat-absorbing block 10 in this cavity 14.
This loam cake 12 is provided with a pair of interface that is connected with feed tube 200 and drain pipe 100 of being used for, according to the flow direction of cooling fluid, with its called after feed liquor interface 18 and go out liquid interface 19.
Be illustrated in figure 4 as the schematic diagram of heat-absorbing block 10 bases 11, the top layer 16 and the cooling fluid of this base 11 are carried out heat exchange, this top layer 16 is the metal sintering layer, has a large amount of micro-pores, when cooling fluid when this feed liquor interface 18 enters this cavity 14, the flow through top layer 16 of this base 11 of cooling fluid is because the existence of this hole, increased the heat exchange area of base 11, strengthened heat exchange effect with cooling fluid.Understandable, this top layer also can have the metal material layer of loose structure for other, for example metal foaming material layer etc.
By above-mentioned introduction as can be known, the present invention is by form loose structure on the base top layer, thereby increase the heat exchange area of base and cooling fluid and strengthen flowing of cooling fluid, enter cavity 14 backs of this heat-absorbing block and the heat exchange effect of base thereby strengthen cooling fluid, make cooling fluid better absorb and take away the heat of base.
