Abstract

The utility model relates to a heat sink for use in the electronic component field, in particular to an electronic radiator for display cards. The electronic radiator for the display cards comprises a substrate (1) in contact and coordination with a heat emitting component, and a plurality of fins arranged in parallel and integrally connected with the substrate (1), wherein each fin (2) is composed of a plurality of fin split sections (3) arranged at intervals; and a heat dissipating channel is formed between every two fins (2) through the spacings between the fin split sections (3). With thetechnical scheme, each fin is divided into a plurality of sections and composed of a plurality of fin split sections alternated with each other; in this way, the contact area of each fin with air is increased by about 20% and then heat is transferred to the air through the heat dissipating channel; the heat dissipation effect is effectively improved by about 10%; furthermore, excellent heat dissipation performance can be still kept and the universality of integrated application is improved while the volume of the radiator is reduced; and the electronic radiator is simple in structure and low in manufacturing cost.

Description

Video card electron-like radiator

Technical field

The utility model relates to the used heat abstractor in a kind of electronic devices and components field, relates in particular to a kind of video card electron-like radiator.

Background technology

Video card technology on the present market is higher direction and develops; The radiator of its application also constantly carries out Renewal Design with the variation of video card; But technically; We roughly can distinguish the problem that is faced as follows: the restriction in first space, the space of display card radiating module are limited in 2 Slot, and the height of video card radiator can only take the space of two host slots at most; It two is heat density problems and since the video card size of processing contract again close after, the heating position of naked crystalline substance will more dwindle, concentrate; Area of chip is more and more littler; Cause the interface resistance of radiator and core anti-increasingly high, it is unreasonable that heat spreader structures designs, and is difficult to rapidly heat taken away from core; It three is cost problems, and video card updates very fast, and the price war between the various brands video card grows in intensity, rationally control cost under the good situation of video card heat radiation guaranteeing, and be each manufacturer's urgent problem.Generally as far as radiator, the many more radiating effects of fin are good more, but this just on the one hand, and what is more important is the restriction of problem as above, make its how video card radiator bottom thermal source is conducted on the fin efficiently and effectively, realize better radiating effect.

The utility model content

For solving the deficiency that exists in the prior art, the utility model provides a kind of video card electron-like radiator that can effectively improve radiating effect, and it is simple in structure.

For realizing above-mentioned purpose; The video card electron-like radiator of the utility model; Comprise with the substrate of heat dissipation element contact matching, with a plurality of fins that laterally arrange that substrate is connected, as the improvement part of the utility model, each fin is made up of the fin split that the multistage spacing is provided with; Between each fin, form heat dissipation channel through the spacing between the fin split.

As the qualification to aforesaid way, the cross sectional shape of above-mentioned fin split is a parallelogram.

Adopt technique scheme,, form by a plurality of fin split spacings through each fin is divided into multistage; Like this, it is about 20% that the contact area of each fin and air is increased, so through heat dissipation channel with heat transferred to air; Effectively raise the radiating effect about 10%, and then make under the situation that the radiator volume dwindles, still can keep good thermal diffusivity; Improve the universal performance of overall applicability, it is simple in structure, low cost of manufacture.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:

Fig. 1 is the front view of the utility model;

Fig. 2 is the vertical view of Fig. 1.

Among the figure:

1, substrate, 2, fin; 3, fin split.

Embodiment

By shown in Figure 1, the video card electron-like radiator of present embodiment comprises a plurality of fins that laterally arrange 2 that are connected with heat dissipation element contact matching substrate 1, with substrate 1, and substrate 1 all adopts aluminum material with fin 2.Can be found out that by Fig. 2 each fin 2 is made up of the fin split 3 that the multistage spacing is provided with, the cross sectional shape of each fin split 3 is a parallelogram, between each fin 2, forms heat dissipation channel through the spacing between the fin split 3.

Through fin 2 being arranged to a plurality of fin splits 3, between each fin 2, because the spacing between the fin split 3; Formed a passage that supplies circulation of air, the fin 2 and the contact area of air are increased, made under each heat spreader structures of equal volume; The heat of substrate 1 distributes through the heat dissipation channel that forms between fin split 3 and the fin 2, makes heat conduction more effective fully; The uniformly dispersing of favourable heat, its radiating effect strengthens.

In addition, what be worth explanation is, the cross sectional shape of each fin split 3 also can be other shapes, like prismatic, trapezoidal etc., all belongs to the protection range of the utility model.

Claims (2)

1. video card electron-like radiator; Comprise a plurality of fins that laterally arrange (2) that link with the substrate (1) of heat dissipation element contact matching, with substrate (1) one; It is characterized in that: each fin (2) is made up of the fin split (3) that the multistage spacing is provided with; Between each fin (2), form heat dissipation channel through the spacing between the fin split (3).

2. video card electron-like radiator according to claim 1 is characterized in that: the cross sectional shape of described fin split (3) is a parallelogram.
