Abstract

The utility model relates to a heat radiating apparatus for a heat pipe and comprises a bottom plate, a top plate opposite to the bottom plate at intervals, a heat radiating piece group arranged between the bottom plate and the top plate and the heat pipe for the heat connection of the bottom plate and the top plate, wherein the heat pipe is at least provided with two heat conduction sections connected between the bottom plate and the top plate. Because the heat pipe comprises the two heat conduction sections arranged between the bottom plate and the top plate, the heat generated by a heat source is passed to the top plate through the two heat conduction sections after being absorbed by the bottom plate to be homogeneously diffused on the whole heat radiating apparatus. Therefore, one heat pipe in the heat radiating apparatus can achieve the effect of passing the heat of two traditional heat pipes, therefore the performance and the cost ratio of the heat radiating apparatus can be increased. The higher performance can be obtained by using the lower cost.

Description

Heat-pipe radiating apparatus

[technical field]

The utility model relates to a kind of heat abstractor, refers in particular to a kind of heat-pipe radiating apparatus in order to cooling electronic components.

[background technology]

Along with developing rapidly of electronic industry, the arithmetic speed of electronic components such as central processing unit increases substantially, and the heat of its generation also increases severely thereupon, and how the heat with electronic component distributes, and to guarantee its normal operation, is the problem of industry in research always.For effectively distribute the heat that central processing unit produces in running, industry installs auxiliary its heat radiation of a radiator usually additional on the central processing unit surface, desires to make central processing unit self temperature maintenance in normal range of operation.

Show a kind of radiator 100 of typical structure as Fig. 1, this radiator 100 comprises two heating panels 102 that are parallel to each other and are provided with at interval, be located at one group of fin 104 between two heating panels 102 and connect the C type heat pipe 106 of this two heating panel 102, and the two ends of this C type heat pipe 106 are connected with two heating panels 102 respectively.The heat transferred that central processing unit produces is to heating panel 102, simultaneously heat is delivered on the heating panel of far-end 102 rapidly by the phase change of hydraulic fluids in the heat pipe 106, by groups of fins 104 heat is distributed again, reach the purpose of cooling central processing unit.For the heat that central processing unit is produced distributes fast in air, usually make heat be spread on the radiator 100 nationality comparatively uniformly in the mode of the quantity that increases heat pipe 106 to promote radiating effect, but increase a heat pipe 106 and promptly need increase operations such as two heat pipes 106 seal, this operation is compared one-tenth such as length that increase heat pipe and was said originally and want high, so the quantity of increase heat pipe 106 will cause the cost increase of entire radiator 100.

[summary of the invention]

The utility model provides a kind of heat-pipe radiating apparatus of tool high performance-price ratio.

The heat-pipe radiating apparatus of the utility model embodiment comprises a base plate, one of at interval relative with base plate top board, be located between base plate and the top board a groups of fins and with base plate and the hot linked heat pipe of top board, wherein this heat pipe has at least two heat conduction sections to be connected between base plate and the top board.

This execution mode compared with prior art has following advantage: because heat pipe comprises the two heat conduction sections of being located between base plate and the top board, the heat that thermal source produces is absorbed the back by base plate and is delivered to top board by this two heat conduction section, a heat pipe can be realized the heat-transfer effect of two conventional heat pipe, thereby the performance of heat abstractor and benefit cost ratio improve greatly, can obtain higher performance at lower cost.

[embodiment]

The heat-pipe radiating apparatus of the utility model embodiment is mainly used in electronic components such as cooling central processing unit.

Fig. 2 is to the heat-pipe radiating apparatus that Figure 4 shows that the utility model first embodiment.This heat abstractor 1 comprises a groups of fins 3, a heat pipe 5, a top board 7 and a base plate 9.

Groups of fins 3 forms by some fin that are parallel to each other are stacked successively, and is respectively equipped with a

groove

32,34 in groups of fins 3 both sides.

Top board 7 and base plate 9 are made by heat conductivility good material such as copper, aluminium etc., and this top board 7 and base plate 9 are located at groups of fins 3 relative both sides.Top board 7 is provided with a groove 72, and this groove 72 docks the part in order to ccontaining heat pipe 5 with the groove 32 of groups of fins 3 one sides.Base plate 9 is provided with a groove 92, and this groove 92 docks the another part in order to ccontaining heat pipe 5 with the groove 34 of groups of fins 3 opposite sides.In addition, four of base plate 9 jiaos are respectively equipped with a buckle ear in order to this heat abstractor 1 is fixed on the thermal source.

Heat pipe 5 is hollow, and it comprises a heat release section 52, two

endotherm sections

54,56 and the two heat conduction sections 58 that heat release section 52 is communicated with two endotherm sections 54,56.Heat release section 52 is arranged in the groove 72 on the top board 7, and contacts with groups of fins 3.Two

endotherm sections

54,56 extend and are arranged in the groove 92 on the base plate 9 from heat release section 52 two ends bendings, and this two

endotherm section

54,56 staggers mutually and is parallel to heat release section 52.Two heat conduction sections 58 are between base plate 9 and top board 7, and this two heat conduction section 58 is positioned at the both sides of groups of fins 3.

During use, base plate 9 contacts with thermal source and absorbs heat, and two

endotherm sections

54,56 of heat pipe 5 evenly are diffused into entire heat dissipation device 1 with the heat absorption of base plate 9 and then by two heat conduction sections 58 with the heat of thermal source.

In actual use, also can change heat pipe 5 occupation modes promptly: heat pipe 5 is put upside down use, heat pipe is comprised place the endotherm section on the base plate to reach two heat release section that contact with top board.At this moment, the heat that thermal source produces relies on two heat conduction sections of heat pipe to be diffused into top board, and then the heat of thermal source is evenly distributed to the entire heat dissipation device, can obtain preferable radiating effect equally.

Compare with traditional radiator, a heat pipe 5 among this embodiment is diffused into the heat that thermal source produces on the top board 7 along different heat-transfer paths by its two heat conduction section 58, and then conduct heat and distribute to groups of fins 3, reach the heat-transfer effect of two conventional heat pipe, thereby improve the performance of heat abstractor 1 and the ratio of cost.

Above-mentioned is an embodiment of the utility model heat-pipe radiating apparatus, but the utility model is not limited in this, as: in the foregoing description, heat pipe comprises an endotherm section and two heat release section, can change both quantity according to actual conditions, can repeatedly have two endotherm sections that contact with base plate and four heat release section that contact with top board etc. around the home as heat pipe.
