Description
FIELD OF THE INVENTION
[0001] 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
[0002] 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.
[0003] Please refer to FIG. 1, the conventional heat dispersing
structure 1a employs conduction concept to perform heat dispersing,
so that the structure thereof is composed of an open-up structure,
formed by arranged plural fins 13a, and a heat conductor 11a, and
is fixed on the heat source by slice fixing piece 12a. The open-up
structure such as fins 13a are formed to increase the surface areas
contacting with air as far as possible. However, after the heat
conductor 11a transmits the heat to the fins 13a, the heated air
will stay around the gaps of the fins 13a 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.
[0004] Theoretically, for heat source and the heat conductor 11a,
although this kind of heat dispersing structure 1a is capable of
heat transmission, it still has many limitations:
[0005] First, the heat dispersing manner of the heat conductor 11a:
Since the heat from the heat conductor 11a only can be dispersed by
fins 13a, it is very easy to cause baking phenomenon.
[0006] Secondary, the shape and direction of the heat conductor
11a: For achieving better heat dispersing effect, the fins 13a are
usually disposed at the normal direction of the heat conductor 11a,
but it might also cause a short route of the airflow formed by fan,
so that air convection can not work effectively.
[0007] 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 13a or the heat
conductor 11a, additional noises will be produced.
[0008] Finally, the limited life time of the heat dispersing
structure 1a: Because the conventional heat dispersing structure
1a, which has larger surface area and closely arranged fins 13a,
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.
[0009] Hence, the conventional heat dispersing structure is mainly
disadvantageous that:
[0010] 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.
[0011] 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.
[0012] 3. The conventional heat dispersing structure needs to rely
on additional accessories, such as fan, to produce airflow and
generate convection.
[0013] 4. The air flowing of the conventional heat dispersing
structure is not smooth and is easy to cause noise.
[0014] 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
[0015] 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.
[0016] 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.
[0017] 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.
[0018] 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.
[0019] 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.
[0020] Consequently, the present invention is advantageous
that:
[0021] 1. The heat dispersing module provides simple structure and
low manufacturing cost which are both suitable for mass
production.
[0022] 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.
[0023] 3. The heat dispersing module can produce forced air
convection to increase heat dispersing efficiency.
[0024] 4. The heat dispersing module produces stable and smooth
airflow with small noise and provides great maintaining
property.
[0025] 5. The heat dispersing module fixes the fan by tenons for
facilitating exchanging and maintenance.
[0026] 6. The structure of the heat dispersing tubes in the heat
dispersing module can actively produce air convection and have a
long life time.

[0036] Please refer to FIG. 2 and FIG. 3. The present invention
provides a heat dispersing module 1 including a heat conductor 2,
plural fixing pieces 3, a heat dispersing tube set 4 and a fan 5,
wherein:
[0037] The heat conductor 2 is a block having a plane surface 21 at

[0038] Each fixing piece 3 has a locking hole 31 mounted at one end
thereof for penetrating a locking element, such as a screw, which
further penetrates the locking hole 221 of the fixing slot 22 of
the heat conductor 2, so as to lock the fixing piece 3 in the
fixing slot 22 of the heat conductor 2.
[0039] The heat dispersing tube set 4 is stacked by plural heat
dispersing tubes 41, wherein one tube end 42 is formed to have
inward indentation, for preventing from damaging blades or rotator

resistance, such as tin, for attaching to the upper surface plane
21 of the heat conductor 2, and two tube set sides 43 adjacent to
the tube ends 42 are formed to have engaging troughs 44.
[0040] The fan 5 has a frame 51 whose two sides respectively have a

to the channels 411 inside the heat dispersing tubes 41 to cause
air convection in the tube. And, as the fan 5 located at the tube
ends 42 is running, the air flowing can be strengthened and passes
through the heat dispersing tube set 4 so as to enhance the heat

surface plane 21 of the heat conductor 2 is formed to have plural
indentations 211 at the midline thereof and plural troughs 212
respectively at the two opposite sides thereof, and all the heat
conductive pieces 23, 24 are coated by material of low heat
resistance, such as tin, for respectively attaching to the

the air duct 6 has tenons 61 mounted thereon for fixing and
engaging with the engaging troughs 44 of the heat dispersing tube
set 4. Alternatively, as shown in FIG. 7, the bendable air duct 6
also can be mounted between the fan 5 and the heat dispersing tube
set 4 for communicate the heat dispersing tube set 4 to
