CN2674651Y - Single fan double blade radiating structure - Google Patents

Abstract

The utility model relates to a single fan double blades radiating structure, mainly comprising a fan and a radiating sheet. Wherein, the fan is extended down to a proper length by the shaft center of the main blade and pivots an auxiliary blade on the bottom end of the shaft center. The surface of the radiating sheet is provided with a circular slot corresponding to the auxiliary blade. The fan is fixed on the top of the radiating sheet, and the auxiliary blade is just arranged in the circular slot. Therefore, the wind force of the fan is more centralized to increase the radiation efficiency of the CPU.

Description

The biparting leaf radiator structure of single fan

Technical field

The utility model relates to the biparting leaf radiator structure of a kind of single fan, refers to that especially a kind of wind-force that makes is more concentrated, increases the radiator structure of radiating efficiency.

Background technology

Press; The employed radiator structure of general CPU (central controller), as shown in Figure 1, usually establish in the CPU10 surface with a fin 11, again in fin 11 upper fixed one fan 12, fin 11 is fixed on the circuit board 14 with fixed mount 13, in order to do high temperature by fin 11 conduction CPU10, distributed via fan 12, the radiator structure that this kind is known is because fixed mount 13 is little with the space of circuit board 14 again, windage is big, therefore, wind-force only can outwards be shed by fin 12 both sides, make wind-force to concentrate, relative feasible part high temperature can't be discharged, and causes radiating effect unclear, the CPU10 that improves day by day for processing speed more do not have be suitable for, very undesirable.

Summary of the invention

The purpose of this utility model is to provide a kind of single fan biparting leaf radiator structure, fin is placed the CPU surface, wind-force is concentrated to centre, to eliminate the windage of fixed mount and circuit board by the major and minor fan of this serial connection, make the high temperature of CPU be able to quick discharge, improve the efficient of heat radiation.

The utility model is to provide a kind of single fan biparting leaf radiator structure, mainly comprise a fan and a fin, wherein this fan extends suitable length downwards by the axle center of main flabellum, articulate a secondary flabellum in the bottom in this axle center, this fin then is provided with the circular groove corresponding to secondary flabellum in the surface, this fan is fixed in the fin top, and this pair flabellum just places in the circular groove.

The utility model makes the wind-force of fan more concentrated, to improve the radiating efficiency of CPU.

Embodiment

Please consult Fig. 2,3 simultaneously, the utility model mainly comprises a fan 2 and a fin 2, wherein, this fan 2 is to be provided with a framework 21, in this framework 21, establish with a main flabellum 22, extend suitable length downwards by the axle center 23 of this main flabellum 22 after, articulate a secondary fan 24 in the bottom in this axle center;

This fin 3 is to be provided with most fins 31, and establishes with the circular groove 32 corresponding to secondary fan 24 in its surface;

Combination by aforementioned components, as shown in Figure 4, this fan 2 is the tops that are locked in fin 3, and secondary fan 24 wherein just can be placed in the circular groove 32 of fin 3, in order to do the surface that fin 3 is placed CPU10, and be fixed in circuit board 14 with fixed mount 13, so, when the main flabellum 22 of fan 2 when rotating, can be with its secondary fan 24 that is connected in series of relative drive, wind-force is concentrated to the centre of fin 3, high temperature is discharged, to reach high efficiency thermolysis.

See also Fig. 4, the utility model is when using, and when fan 3 rotated, the fan 3 set major and minor flabellums 22,24 of serial connection produced equidirectional rotation simultaneously, so, formed wind-force is except the direction of former oriented fin 3 both sides discharging high temperature, because this pair fan 24 is to place in the circular groove 32, therefore, make the wind-force of its generation be able to concentrate to centre, with the windage of reduction fixed mount 13, high temperature is discharged rapidly, and then improve the efficient of heat radiation with the space of circuit board 14.

In sum, the utility model is with the fan of serial connection, and the wind-force that fan is produced is able to concentrate to the centre of fin, to improve the radiating effect of CPU, is the design of a practicality, really belongs to a creation with novelty, proposes patent application in accordance with the law.

Claims (1)
