Abstract

The utility model relates to a heat pipe radiator assembly, assisting the heating electronic elements, such as the central processing unit, etc to radiate, and including at least a heat pipe and a plurality of radiation fins. The heat pipe is provided with a heat absorption section, at least a heat output section, and a bending section connecting the heat absorption section with the heat output section, wherein, the radiation fins are provided with a plurality of perforations. The heat output section of the heat pipe is perforated through the perforations of the radiation fin. The extending direction length along the heat absorption section of the heat pipe of the perforations of the partial radiation fins nearing to the bending section of the heat pipe is greater than those of the corresponding perforations of other radiation fins. During the process that the heat pipe is plugged into the radiation fins, the perforations that the heat pipe mutually supporting connected with the bending section of the heat pipe are provided with enough surplus, accordingly, the mutually interference between the bending section and the radiation fins and the occurrence of the radiation fins deforming are avoided.

Description

The heat-pipe radiator combination

[technical field]

The utility model is about a kind of heat abstractor, is meant a kind of heat-pipe radiator combination of using heat pipe and can effectively improving heat dispersion especially.

[background technology]

Along with large scale integrated circuit continuous advancement in technology and extensive use, the development of information industry is advanced by leaps and bounds, computer is widely used in all trades and professions, especially the application of personal computer becomes basically universal, in order to adapt to the development trend that data processing amount constantly increases and the real-time requirement improves, inevitable requirement computer run speed improves constantly.As everyone knows, central processing unit is the core parts of computer system, the performance of the whole computer of good and bad directly decision of its performance, and therefore, the high-frequency high-speed processor is constantly released.But because the high-frequency high-speed operation makes the processor unit interval produce a large amount of heat, if these heats of untimely eliminating will cause the rising of processor self temperature, safety and performance to system cause very big influence, and heat dissipation problem has become the problem that must will solve when each high speed processor of new generation is released at present.Usually industry is all installed auxiliary its heat radiation of radiator on chips such as central processing unit.Simultaneously, fan is installed on radiator, so that forced draft to be provided the heat of radiator is distributed fast, thereby can carry out more efficiently heat radiation central processing unit.

As shown in Figure 1, it discloses existing heat abstractor, and this heat abstractor comprises a pedestal 1 ', a groups of fins 2 ' and a heat pipe 3 '.This heat pipe 3 ' comprises first end 30 ', the second end 32 ' and connects the kink 34 ' of first end 30 ' and the second end 32 ', this groups of fins 2 ' is provided with the second end 32 ' the directly insertion of open-work 20 ' for this heat pipe 3 ', yet the kink 34 ' of heat pipe 3 ' and the open-work 20 ' edge of groups of fins 2 ' interfere during insertion, cause groups of fins 2 ' buckling deformation, thereby influence its outward appearance and heat dispersion.

[summary of the invention]

The purpose of this utility model is to provide a kind of and avoids in installation process heat pipe and fin to interfere and cause the not good heat-pipe radiator combination of radiating effect.

The purpose of this utility model realizes by following technical proposal:

The combination of the utility model heat-pipe radiator, the heat radiation of heat-generating electronic elements such as secondary CPU, comprise at least one heat pipe and some radiating fins, heat pipe has an endotherm section, at least one heat release section and connects the kink of endotherm section and heat release section, wherein radiating fin is provided with some perforation, the heat release section of heat pipe is arranged in the perforation of radiating fin, near the perforation of the part radiating fin of heat pipe kink along the length of heat pipe heat-absorbing section bearing of trend length greater than other radiating fin respective perforations.

The combination of the utility model heat-pipe radiator will enlarge near the perforation of heat pipe kink, make heat pipe in inserting the radiating fin process, enough surpluses be arranged, avoided kink and radiating fin to interfere and radiating fin generation warpage with perforation that the kink of heat pipe connects.

[description of drawings]

With reference to the accompanying drawings, the utility model will be further described in conjunction with the embodiments.

Fig. 1 is an existing heat abstractor three-dimensional exploded view.

Fig. 2 is the three-dimensional exploded view of the utility model heat-pipe radiator combination.

Fig. 3 is the constitutional diagram of the utility model heat-pipe radiator combination.

[embodiment]

The utility model heat-pipe radiator combination is dispelled the heat to it in order to be installed on heat-generating electronic elements surface such as central processing unit.

See also Fig. 2 and Fig. 3, the utility model heat-pipe radiator combination preferred embodiment comprises a pedestal 10, two groups of heat pipes 20,30 and some radiating fins 40.

It is tabular and have a upper and lower surface that this pedestal 10 is level, and the upper surface central processing unit (figure does not show) that is sticked waits heat-generating electronic elements surperficial and absorb the heat of its generation, and the lower surface level offers and heat pipe 20,30 corresponding parallel grooves 12.

These two groups of heat pipes 20,30 all are " ㄇ " shape, have the parallel heat release section 24,34 of horizontal endotherm section 22,32, the left and right sides and connect endotherm section 22,32 respectively and the kink 23,33 of heat release section 24,34, endotherm section 22,32 places in pedestal 10 grooves 12 and by welding manner fixedlys connected with pedestal 10, absorb the heat of pedestal 10, heat release section 24,34 be positioned at pedestal 10 belows and with pedestal 10 approximate vertical.

Above-mentioned radiating fin 40 is parallel to each other horizontally and is set on the heat release section 24,34 of heat pipe 20,30 with certain interval, absorbs the heat of heat pipe 20,30.Wherein each radiating fin 30 is rectangular, certainly, also can be other shape.Radiating fin 40 is provided with two groups of perforation 26,36, its middle punch 26 is used to wear the heat release section 24 of heat pipe 20, this perforation 26 is near radiating fin 40 wherein on one side, and perforation 36 is used to wear the heat release section 34 of heat pipe 30, and this perforation 36 is near the relative edge on radiating fin 40 above-mentioned one side.Near the perforation 26,36 of last three to four radiating fins 40 of pedestal 10 along the length of endotherm section 24,34 bearing of trends length greater than other radiating fin 40 respective perforations 26,36.So, when the heat release section 24,34 of heat pipe 20,30 is inserted in the perforation 26,36, and the perforation 26,36 that the endotherm section 22,32 of heat pipe 20,30 and the kink 23,33 between the heat release section 24,34 connect has enough surpluses, thereby avoids kink 23,33 and radiating fin 40 to interfere.

Understandable, heat pipe of the present utility model is not limited to " ㄇ " shape, and the endotherm section of this heat pipe also can directly contact with electronic component and not need pedestal.
