Description

A kind of computer heat radiating device

Technical field

The present invention relates to computer realm, relate in particular to a kind of computer heat radiating device.

Background technology

The use of computing machine has obtained very large universal, but computer to dissipate heat performance is large multi-user pay close attention to most a bit, in hot summer, or in the concentrated region of work intensity, as Internet bar, intensive workplace etc., be easy to make computing machine heating itself, when hot soak condition, be easy to make computing machine blue screen, or burn inner electronic devices and components, the loss that causes vital document, lose greatly, and need repairing, cost of idleness and resource.

In prior art, people adopt the cooperation of aluminium base and fan to dispel the heat, but, as everyone knows, although the cost of aluminium is lower, heat conductivility is not best, can not be very efficient by the temperature conduction on computer hardware out, thereby after long-term use, hardware Yin Wendu can not get effectively conduction out, thereby causes burning.

Summary of the invention

In view of this, be necessary to provide a kind of computer heat radiating device that can effectively conduct and reduce hardware temperatures.

The present invention realizes like this, a kind of computer heat radiating device, comprise a plurality of ring-type heat dissipation metal plates, the diameter single-candidate of described a plurality of ring-type heat dissipation metal plates is successively decreased, diameter circlet shape heat dissipation metal plate is arranged in the ring-type heat dissipation metal plate inner chamber that diameter is large, and a plurality of ring-type heat dissipation metal plates are coaxially installed, in described a plurality of ring-type heat dissipation metal plate, height in peripheral ring-type heat dissipation metal plate is lower than in the interior ring-type heat dissipation metal plate enclosing, the xsect of described ring-type heat dissipation metal plate is bullet shaped, ring-type heat dissipation metal plate comprises pedestal, heat-sink shell, heat-conducting layer and heat dissipating layer, described heat-sink shell, heat-conducting layer and heat dissipating layer are all located on pedestal, and the center of heat-sink shell in pedestal, heat-conducting layer is wrapped on the outside surface of heat-sink shell, heat dissipating layer is wrapped on the outside surface of heat-conducting layer,

The material of described pedestal and heat-sink shell is identical, by distributing by weight, comprises that silicon 20%～40%, copper 30%～50%, gold 5%～15% and aluminium 10%～30 form, by die cast after even mixing;

The material of described heat-conducting layer is: by distributing by weight, comprise that aluminium 20%～60% and copper 40%～80% form, by die cast after even mixing;

The material of described heat dissipating layer is aluminium.

Further, the material of described pedestal and heat-sink shell is identical, by distributing by weight, comprises that silicon 30%, copper 40%, gold 10% and aluminium 20% form, by die cast after even mixing.

Further, the material of described heat-conducting layer is: by distributing by weight, comprise that aluminium 40% and copper 60% form, by die cast after even mixing.

The advantage of a kind of computer heat radiating device provided by the invention is: the present invention is simple and reasonable, by ring-type heat dissipation metal plate is divided into pedestal, heat-sink shell, the array configuration of heat-conducting layer and heat dissipating layer, because the material of pedestal and heat-sink shell is silicon, copper, the array configuration of gold and aluminium, due to silicon, copper, the heat conductivility of gold is far longer than the heat conductivility of aluminium, thereby easily the temperature on hardware is derived, promote the radiating rate of hardware, heat-conducting layer is mainly the combination of aluminium and copper, the main conduction heat that plays a part, the material of heat dissipating layer is aluminium, main plaing a part dispelled the heat, by ring-type heat dissipation metal plate is designed to bullet shaped, mainly in order to increase the area of dissipation of outside, improve radiating efficiency, thereby avoided because of hardware temperatures too high, cause the phenomenon that parts burn to occur, save great amount of cost resource.
