Description

FIELD OF THE INVENTION

The present invention is related to a heat dispersing module, and more particularly to a heat dispersing module which is designed based on the property of heat dispersing tube and which disperses heat through air convection.

BACKGROUND OF THE INVENTION

There are three types of heat transmission, conduction, convection and radiation. Conduction utilizes medium to transmit heat from high temperature to low temperature, convection is formed by circular flowing of heated liquid (air or water) which is caused by density variation, and radiation can transmit heat without any medium. For liquid, the major and most effective manner to transmit heat is convection.
Please refer to FIG. 1, the conventional heat dispersing structure 1 a employs conduction concept to perform heat dispersing, so that the structure thereof is composed of an open-up structure, formed by arranged plural fins 13 a, and a heat conductor 11 a, and is fixed on the heat source by slice fixing piece 12 a. The open-up structure such as fins 13 a are formed to increase the surface areas contacting with air as far as possible. However, after the heat conductor 11 a transmits the heat to the fins 13 a, the heated air will stay around the gaps of the fins 13 a and not disperse, so that it has to utilize additional accessories, such as fan, to increase the flowing of air, thereby achieving the effect of heat dispersing.
Theoretically, for heat source and the heat conductor 11 a, although this kind of heat dispersing structure 1 a is capable of heat transmission, it still has many limitations:
First, the heat dispersing manner of the heat conductor 11 a: Since the heat from the heat conductor 11 a only can be dispersed by fins 13 a, it is very easy to cause baking phenomenon.
Secondary, the shape and direction of the heat conductor 11 a: For achieving better heat dispersing effect, the fins 13 a are usually disposed at the normal direction of the heat conductor 11 a, but it might also cause a short route of the airflow formed by fan, so that air convection can not work effectively.
Further, the problem of noise: Since the flow route driven by fan is short and the airflow can not inhale and exhale smoothly, when airflow passes through or hits the fins 13 a or the heat conductor 11 a, additional noises will be produced.
Finally, the limited life time of the heat dispersing structure 1 a: Because the conventional heat dispersing structure 1 a, which has larger surface area and closely arranged fins 13 a, might easily be attached by dusts due to contact or static electricity, the efficiency of heat transmission will be influenced directly, and further, if being under a bad environment or operating for a long time, the fan might even stuck which not only blocks airflow, but also reduces the service life thereof.
Hence, the conventional heat dispersing structure is mainly disadvantageous that:
1. In the conventional open-up heat dispersing structure, the shapes of the fixing piece and the heat conductor are too complicated which accordingly increase the manufacturing cost.
2. In the conventional open-up heat dispersing structure, plural fins are arranged closely, so that the air flowing caused by fan might have disordered directions, thereby many disturbances and vortexes may form turbulence, which reduces the efficiency of heat dispersing by convection and causes baking phenomenon.
3. The conventional heat dispersing structure needs to rely on additional accessories, such as fan, to produce airflow and generate convection.
4. The air flowing of the conventional heat dispersing structure is not smooth and is easy to cause noise.
5. The conventional heat dispersing structure is easily attached by dusts which might influence the heat conduction and reduce the service life thereof.

SUMMARY OF THE INVENTION

The object of the present invention is to improve the conventional heat dispersing structure, which does not conform to the character of the heat convection of airflow, by providing a heat dispersing module which is mainly composed of heat dispersing tubes which utilizes heat convection to disperse heat.
For achieving the object described above, the present invention provides a heat dispersing tube set which is mainly composed of tubular heat dispersing structures provided by the same applicant and designed based on the character thereof.
A heat dispersing module is disclosed including a heat conductor, plural fixing pieces, a heat dispersing tube set and a fan, wherein the fixing pieces are locked around the heat conductor, the heat dispersing tube set is fixedly mounted on the heat conductor, and the tube ends of the heat dispersing tube set is engaged with the fan by tenons.
Moreover, since the heat dispersing medium is air and the heat dispersing manner is convection, according to the property of the heat dispersing tube, the produced heat can be gathered in the heat dispersing tube, and then, the fan can enhance the air convection for further heat dispersing.
The present invention is characterized in that: the air flowing direction provided by fan is along the direction of the heat dispersing tube set, so that the airflow inside the heat dispersing tube set is smooth, thereby reducing noise production and dust attachment; the contact area between the heat conductor and the heat dispersing tube set is large and suitable for heat conduction; the structures of heat conductor and fixing pieces are simple with low manufacturing cost; and the heat dispersing tube set itself can actively produce heat convection even when the fan is not working.
Consequently, the present invention is advantageous that:
1. The heat dispersing module provides simple structure and low manufacturing cost which are both suitable for mass production.
2. The heat dispersing module can effectively guide air flowing for reducing turbulence and can disperse heat by the convection manner which conforms to liquid property.
3. The heat dispersing module can produce forced air convection to increase heat dispersing efficiency.
4. The heat dispersing module produces stable and smooth airflow with small noise and provides great maintaining property.
5. The heat dispersing module fixes the fan by tenons for facilitating exchanging and maintenance.
6. The structure of the heat dispersing tubes in the heat dispersing module can actively produce air convection and have a long life time.
