Description
Technical field
The present invention relates to a kind of heat abstractor, particularly a kind of heat abstractor that is used for cooling electronic components.
Background technology
Along with the develop rapidly of electronic industry, electronic component (as the central processing unit) speed of service constantly promotes, and produces a large amount of heats during operation, and itself and system temperature are raise, and influences its operation stability then.For guaranteeing that electronic component can normally move, heat abstractor is installed usually thereon, discharge the heat that it produces.
The traditional solution of electronic element radiating problem is normally installed a radiator on each heat-generating electronic elements, this radiator comprises the base plate that closely contacts with electronic component, is located at the some radiating fins on the base plate.Along with the electronic component arithmetic speed grows with each passing day, for further satisfying radiating requirements, also can in radiator, wear heat pipe, in one side or pre-portion one fan is installed and be distributed to promote air flows to accelerate heat, simultaneously such heat abstractor is except that radiating efficiency has greatly improved on than original radiator basis, and dimension volume also increases much.But along with the arrival in digital code information epoch, the compact main trend that becomes current electronic product, its manufacturing process be also constantly towards the development of high-density packages and multifunctional direction, and the distance between electronic component such as the chip is more and more littler and caloric value is increasing.Therefore in actual applications, when distance between a plurality of heat-generating electronic elements is very little, if adopting independently respectively, heat abstractor dispels the heat to keep the normal operation of system to it, not only can make the radiator structure of system disperse complexity to cause the system space waste, and because the very little size that also can limit independent heat abstractor of spacing between electronic component, thereby the heat dispersion of system is very restricted.
Summary of the invention
In view of this, be necessary to provide a kind of heat abstractor of adaptive two or more electronic components simultaneously.
A kind of heat abstractor, be used at least two electronic element radiatings, comprise at least two group heat pipes that a pedestal, is positioned at groups of fins on the pedestal, pedestal and groups of fins heat conduction are connected, described pedestal is provided with and is used at least two absorber plates that contact with described at least two electronic components respectively, described at least two absorber plates are connected with groups of fins by the wherein one group of heat pipe in the described two group heat pipes respectively at least, each heat pipe in this group heat pipe all is connected with groups of fins with absorber plate, and is separate with respectively organizing between the heat pipe of different absorber plates connections.
Above-mentioned heat abstractor can dispel the heat to two heat-generating electronic elements, its pedestal is provided with two absorber plates respectively and contacts with electronic component, by two groups of heat pipes that are connected with two absorber plate heat conduction respectively heat evenly is delivered on the same groups of fins again, and heat is distributed fast.
With reference to the accompanying drawings, the invention will be further described in conjunction with specific embodiments.
