Abstract

The utility model relates to an integrated type combing heat pipe radiator, comprising a base board buckling in CPU surface by a utensil button, wherein, the base board is provided with a parallel groove, and a heat pipe is embed in the groove fixedly; a plurality of parallel local heat sinks are firmly arranged above the heat pipe; the other end of the heat pipe is weaved and fixed in a plurality of parallel strange heat sinks; the parallel strange sinks are arranged in a fixed support, the fixed support is provided with a fan seat and a fan at the back firmly, and the fixed support is arranged on the computer machine case at the front. The utility model of the integrated type combing heat pipe radiator divides the heat of the computer CPU into two parts to emanate, a part of heat is given off through the heat pipe to the strange heat sinks, the other part of heat is left away from the CPU through the local heat sinks, thus the heat dissipation ability of the radiator can be greatly improved.

Description

Integrated form and road heat-pipe radiator

[technical field]

The utility model relates to a kind of heat-pipe radiator of computer, refers to a kind of integrated form and road heat-pipe radiator especially.

[background technique]

Along with the growth of computer CPU power, heat dissipation technology is had higher requirement.At present, in desktop computer, the radiator of traditional overhead on heating component mainly adopted in the heat radiation of CPU, the radiating fin of radiator is sticked by Heat Conduction Material on the CPU, top or side at radiating fin are provided with fan, the heat sun value of the monomer of this radiator is higher, and is usually at 0.4～0.8k/w, practical to solving lower-powered CPU heat radiation.Solve the heat radiation of high-power CPU, this radiator has only by the rotating speed that improves fan to be realized, this just causes the noise of system to raise, and the travelling comfort of use descends.Heat pipe heat radiation is applied to the computer to dissipate heat field, and the earliest from laptop, its structural type mainly comprises substrate, heat pipe, fin and the fan that links to each other with CPU.Because the space of notebook computer is limited, notebook is a flat structure with the integrated heat pipe radiator majority, also not in enormous quantities use the on desktop computer.This heat-pipe radiator is characterised in that by some heat pipes, the net quantity of heat that CPU is distributed is directed to the strange land, and the heat of guiding being come by fin and fan is dispersed into the cabinet outside, plays the effect to the CPU heat radiation.Though this heat-pipe radiator can solve the heat dissipation problem of high-power CPU, still have certain restriction, the heat dissipation problem of facing superhigh power CPU just seems unable to do what one wishes.

[model utility content]

The purpose of this utility model is to be to provide a kind of integrated form and road heat-pipe radiator, the heat of CPU is decomposed into two-part to be distributed, part heat directs into the strange land by heat pipe and is dispersed into the cabinet outside, another part heat by local radiating fin the heat band from CPU, thereby can improve the heat dissipation potential of radiator greatly.

The utility model provides a kind of integrated form and road heat-pipe radiator, comprise a metal substrate, one side surface of this metal substrate is fastened on the CPU surface by fastener, this metal substrate is surface and most heat pipe Joint of side in addition, it is characterized in that: also be installed with the local radiating fin that most sheets are arranged in parallel on the surface of the affixed heat pipe of this metal substrate; This this locality radiating fin contacts with this metal substrate, and this heat pipe the other end is interspersed in the strange land radiating fin internal fixation that most sheets are arranged in parallel; This strange land cooling fin front end is installed with a fan, and this radiating fin rear end, strange land is sheathed in the fixed support, and this fixed support rear end is fixedly installed on the computer housing.

Described integrated form and road heat-pipe radiator is characterized in that: this this locality radiating fin also contacts with this heat pipe.

Described integrated form and road heat-pipe radiator, it is characterized in that: this fixed support can be the framework of a hollow, have an interconnective top board and two side plates, the both sides of this top board are respectively equipped with chute, this radiating fin top, strange land is provided with screw, and passes this chute screw lock with the adjusting bolt and fix on the top of this strange land radiating fin.

Described integrated form and road heat-pipe radiator is characterized in that: can be provided with the groove that is arranged in parallel on this metal substrate, an end of heat pipe is fixed in this groove, and this this locality radiating fin and this metal substrate and heat pipe fit tightly.

Integrated form of the present utility model and road heat-pipe radiator, the heat of CPU heat radiation is decomposed into two-part to be distributed, part heat directs into the strange land by heat pipe, be dispersed into the cabinet outside by fin and fan, another part heat is by substrate and local radiating fin, utilize in the cabinet distinguished and admirable the heat band from CPU, be equivalent to the parallel connection of two independent its heat dissipation potentiaies of radiator, thereby expanded the heat dissipation potential of radiator greatly.Thermal resistance R with the heat dissipation potential of nominal radiator represents that the thermal resistance of independent extraction heat-pipe radiator is R1, and the thermal resistance of independent local radiating fin is R2, and the thermal resistance of the utility model integrated form and road heat-pipe radiator is R3, then

R3＝R1×R2/(R1+R2)

So the utility model integrated form and road heat-pipe radiator have been expanded the heat dissipation potential of independent extraction heat-pipe radiator greatly.
