Abstract

The utility model discloses a heat dissipating sheet comprising heat dissipating wings and trenches. The heat dissipating wings are perpendicular to a heat dissipating base plate and are arranged from the centre to two sides of the heat dissipating base plate in a way that shorter heat dissipating wings are closer to the centre than the taller heat dissipating wings, forming a top end with V-shaped cross section. The heat dissipating sheet with such structure achieves uniform heat dissipation and reduces temperature of a heat-generating body by 5% to 10%. In addition, material can be saved by 5% while same performance is maintained.

Description

A kind of fin

Technical field:

The utility model relates to a kind of heat abstractor, particularly relates to a kind of computer realm and uses fin.

Background technology:

In field of computer technology, semiconductor components and devices can produce heat in the course of the work, and the components and parts temperature is increased, and high temperature can influence their operate as normal, and serious meeting damages components and parts.In order to guarantee the operate as normal of each components and parts; Need these heating components and parts are installed additional heat abstractor; Present heat abstractor great majority are thermal component with the fin; Heat during work on the components and parts is transmitted on the fin, utilizes the free convection of air to take away the heat of fin again, thereby reaches the purpose that reduces the components and parts temperature.

There is hot concentration phenomenon in general fin at present, makes the mid portion temperature of fin very high, if improve radiating effect, needing increases its area or increase fan etc., will increase cost accordingly, and can increase volume, is not easy to install.

The utility model content:

Be defective of the prior art more than eliminating, the purpose of the utility model provides a kind of fin with hot dispersion characteristics.Said fin comprises radiating wing; Radiating wing and radiating bottom plate are vertical configuration and are shaped to one; Said radiating wing is arrangement from low to high from the radiating wing of radiating wing to the radiating bottom plate both sides in the middle of the radiating bottom plate; Form " V " tee section on its top, make the middle spread heat of fin arrive the both sides of fin like this, reach in the middle of the fin and the uniform purpose of temperature of both sides.In the preferred version of the utility model, the highest said radiating wing is 4:1 with radiating wing aspect ratio of the end, laterally is provided with profile groove as the said fin of further preferred version.

The fin beneficial effect of this structure is: realize that through not waiting high radiating wing the fin bulk temperature is even, can make the heater temperature descend about 5%～10% like this, can save material about 5% under requiring with performance, correspondingly also provide cost savings and the space.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is done further explanation:

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

Fig. 2 is the front view of the utility model.

Embodiment:

As depicted in figs. 1 and 2, fin is provided with and does not wait high radiating wing 11, and preferably the highest radiating wing is 4:1 with radiating wing aspect ratio of the end; Said radiating wing 11 is arrangement from low to high from the radiating wing of radiating wing to radiating bottom plate 10 both sides in the middle of the radiating bottom plate 10; Form " V " tee section 20 on its top, two limits of its " V " tee section form certain angular relationship, to obtain preferable radiating effect; For obtaining better radiating effect, said fin laterally is provided with profile groove 12.

The above is merely the preferred embodiment of the utility model, does not therefore limit the protection range of the utility model, and every equalization of doing according to the utility model changes with modifying and all belongs in the claim that the utility model contains.

Claims

1. fin; Comprise radiating wing (11); Radiating wing (11) is vertical configuration with radiating bottom plate (10) and is shaped to one; It is characterized in that: said radiating wing (11) is arrangement from low to high from the radiating wing of radiating wing to radiating bottom plate (10) both sides in the middle of the radiating bottom plate (10), and the top of several radiating wings forms " V " tee section (20).

2. fin according to claim 1, base is characterised in that: the highest said radiating wing is 4:1 with radiating wing aspect ratio of the end.
