HEAT-RADIATING DEVICE WITH COMPOSITE RADIATION EFFICIENCY
Abstract
The heat-radiating device with composite heat radiation
efficiency includes a foundation with a heating surface and a
radiating surface. The foundation has an inner space for inserting
phase-changing materials. A heat pipe includes a heat-absorbing end
placed into the foundation and a radiating end protruded out of the
foundation. A radiating fin set is arranged onto the radiating end
of the heat pipe. The heat-radiating device enables the heat
absorbed by the foundation to be quickly guided out of the
foundation through the heat pipe. The radiation area is increased
by the radiating fin set for improved heat radiation efficiency.
The phase-changing material assists in heat absorption and storage
by latent heat, thereby avoiding overheating of foundation and also
helping to control efficiently the heat peak of the foundation.
Furthermore, the heat-radiating device has a composite heat
radiation effect with improved applicability.

BACKGROUND OF THE INVENTION
[0005] 1. Field of the Invention
[0006] The present invention relates generally to a heat-radiating
device, and more particularly to an innovative device with
composite heat radiation efficiency.
[0007] 2. Description of Related Art Including Information
Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
[0008] The known heat-radiating device is widely applied to a heat
sink of a computer's processor. However, the heat generated will
increase markedly with the continuous growth of operating speed of
computer. Therefore, heat-radiating devices need to be improved
functionally to realize enough a heat-radiation effect.
[0009] The known heat-radiating device is typically a plate made of
materials (e.g. copper) of outstanding heat conductivity. One side
of the heat-radiating device is a heating surface, and the other
side is a radiating surface. The heating surface is adhered to the
predefined heat source (e.g. CPU), and the radiating surface is
generally provided with several rows of radiating fins. The
radiating fin aligns with the preset radiator fan, so, it can
diffuse the heat absorbed by the heating surface when the
heat-radiating device is operated. Then, air flow is blown by the
radiator fan for heat radiation purposes. However, the heat
radiation effect of a conventional heat-radiating device is
restrained to a certain degree when the operating speed of the
existing computer improves quickly. If the area of said heat source
remains still, the heat-radiation efficiency could be improved even
if the heating surface of the heat-radiating device is
increased.
[0010] Thus, to overcome the aforementioned problems of the prior
art, it would be an advancement in the art to provide an improved
structure that can significantly improve efficacy.
[0011] Therefore, the inventor has provided the present invention
of practicability after deliberate design and evaluation based on
years of experience in the production, development and design of
related products.
BRIEF SUMMARY OF THE INVENTION
[0012] The heat-radiating device of the present invention enables
the heat absorbed by the foundation to be quickly guided out of the
foundation through a heat pipe. The radiation area is increased by
said radiating fin set for improved heat radiation efficiency.
Also, phase-changing material stored in the inner space of the
foundation assists in heat absorption and storage by latent heat,
thereby avoiding overheating of the foundation and also helping to
control efficiently the heat peak of the foundation. Furthermore,
the heat-radiating device provides a composite heat radiation
effect with improved applicability.
[0013] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.

[0014] FIG. 1 shows a perspective view of the preferred embodiment
of the present invention.
[0015] FIG. 2 shows a sectional view of the preferred embodiment of

DETAILED DESCRIPTION OF THE INVENTION
[0018] The features and the advantages of the present invention
will be more readily understood upon a thoughtful deliberation of
the following detailed description of a preferred embodiment of the
present invention with reference to the accompanying drawings.
[0019] FIGS. 1-3 depict preferred embodiments of a heat-radiating
device with composite radiation efficiency of the present
invention. The embodiments are provided only for explanatory
purposes. The claims set the scope of the present invention.
[0020] The heat-radiating device A comprises a foundation 10,
formed as a 3D block (e.g. rectangular) which defines a heating
surface 11 and a radiating surface 12. The foundation 10 is
provided with an inner space 13. The device A includes a
phase-changing material 20, arranged into the inner space 13 of the
foundation 10, and at least a heat pipe 30. The heat pipe 30
comprises a heat-absorbing end 31 and radiating end 32. The
heat-absorbing end 31 is arranged into the foundation 10 opposite
to the inner space 13, while the radiating end 32 protrudes out of
the foundation 10 at a predefined length.
[0021] There is also a radiating fin set 40, arranged at intervals
onto the radiating end 32 of the heat pipe 30.
[0022] The phase-changing material 20 enables change of physical
shapes, e.g. solid phase to liquid phase conversion. When a
substance is melted, the solid phase is converted into a liquid
phase, such that the heat is then consumed, namely, the heat is
absorbed. The substance is stored by means of latent heat as long
as maintained in a liquid state, and said latent heat will be
discharged, enabling conversion from liquid to solid phase in the
case of solidification of the liquid substance. Said phase-changing
material 20 is made of paraffin, inorganic salt, salt water
compounds and mixtures, carboxylic acid and sugar alcohol, etc.
[0023] Referring to FIGS. 1, 2, and 3, radiating fins 14 are
assembled onto the radiating surface 12 of the foundation 10 and
are used to improve heat radiation effect of the radiating surface
12.
[0024] Referring also to FIG. 4, the radiating surface 12B of the
foundation 10 is a plate.
[0025] Referring to FIG. 3, the foundation 10 is provided
internally with bore grooves 15, wherein the heat-absorbing end 31
of the heat pipe 30 could be inserted.
[0026] Based upon above-specified structures, the heat-radiating
device of the present invention is employed as shown in FIG. 3. The
heat radiation effect is achieved in two aspects. When the
foundation 10 absorbs heat through the heating surface 11, the heat
absorbed by the foundation 10 is quickly guided via the heat pipe
30 (namely, the heat is transferred to radiating end 32 of the heat
pipe 30), then the radiation area is increased by said radiating
fin set 40 for improved heat radiation efficiency. On the other
hand, phase-changing material 20 stored in the inner space 13 of
the foundation 10 assists in heat absorption and storage by latent
heat, thereby avoiding overheating of foundation 10 and also
helping to control efficiently the heat peak of the foundation
10.
