Abstract

A radiator fin is provided, which comprises a baseplate and a plurality of radiator fins fixed on the baseplate, and the top end of the radiator fin is tilted with the baseplate in a specified angle, thus the radiator fin with an excellent heat dissipation effect is ensured.

Description

Fin

Technical scheme

The utility model relates to a kind of fin, and particularly a kind of radiating fin upper end and base plate are inclined to the fin of certain angle.

Background technology

Along with the quickening day by day of the computer CPU speed of service, be used for more and more causing the attention of industry to the radiating effect of the fin of CPU heat radiation, though through repeatedly improvement, present fin has begun not satisfy the heat radiation requirement of CPU.Present common fin such as Fig. 1, Fig. 2, shown in Figure 3, it is made of base plate 1 and some radiating fins 2 that is fixed in abreast on the base plate 1.This fin is installed on the CPU (not drawing among the figure), and fan 3 generally is housed on it, distributes quickly with the heat that CPU is produced.But this fin can produce two problems: the one, and the hot-air that is positioned at the radiating fin bottom is not easy to be taken out of, causes radiating effect not good; The 2nd, just a small amount of air-flow is brought between the radiating fin, and wind a little less than, the heat that can not be well CPU be produced comes out.

Summary of the invention

The purpose of this utility model is to provide a kind of fin, to guarantee better heat radiating effect.

Fin provided by the utility model, it comprises base plate and plurality of fixed in the radiating fin of base plate, and is inclined to certain angle with base plate on this radiating fin, thereby guarantees that this fin has better heat radiating effect.

Embodiment

Below in conjunction with accompanying drawing the utility model is made further description.

As Fig. 4, shown in Figure 5, the utility model fin 10 comprises base plate 12, cylinder 14 and some radiating fins 16.This cylinder 14 is fixed on the base plate 12.This radiating fin 16 is arranged in circular, and its end is fixed in around the cylinder 14, and the bottom is fixed on the base plate 12, so that this radiating fin 16 is firmly fixed on the base plate 12.Certainly, this radiating fin 16 also can only be fixed on the cylinder 14, and is fixed on indirectly on the base plate 12 by cylinder 14.These radiating fin 16 equal oblique arrangement spend (75 ° of left and right sides are preferable) with the angle of base plate 12 less than 90, and each radiating fin 16 bend certain angle (being roughly 15 °) at an upper portion thereof.

The utility model radiating fin is because oblique arrangement and its top bending certain angle (as shown in Figure 6), thereby the air-flow that fan 20 produces during work can enter the radiating fin core along the oblique angle, thereby can produce the more air exchange, more hot-air is brought out, also avoid gathering of radiating fin bottom hot-air, therefore can significantly increase radiating effect.And the angle that this radiating fin upper end tilts is roughly identical with wind direction, brushes thereby this fin can be subjected to stronger air-flow, is more conducive to heat radiation.Moreover this radiating fin is arranged in circular, and is similar to fan-shaped, thereby the gap between this radiating fin is corresponding with wind direction, so also can increase its radiating effect.

Certainly, this radiating fin 16 also can be oblique arrangement or only bending at an upper portion thereof, and perhaps other similar mode needs only these radiating fin 16 upper ends and base plate 12 inclination certain angles, can reach the effect that increases heat radiation.
