Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a solar heat collector, in
particularly to a solar heat collector having heat pipe.
[0003] 2. Description of Related Art
[0004] Under the rising conscience of environmental protection and
the threat of energy crisis, safer and less-polluting solar
radiation energy is widely accepted by people. However, how to
effectively and fully convert the solar radiation energy is the
long term issue needed to solve. In available applications of solar
radiation energy, solar heat collector is a product successfully
commercialized and having economic interest. In order to improve
the conversion efficiency of the solar radiation, the heat pipe had
been successfully used in the solar hear collector as a heat
conductive element.
[0005] FIG. 1 and FIG. 2 are respectively a perspective view and a
cross sectional view of the conventional solar heat collector. As
FIG. 1 shows, the solar heat collector 1a includes a heat exchanger
10a, a plurality of branch tubes 20a inserted into the heat
exchanger 10a, and a plurality of heat pipes 30a respectively
arranged in the branch tubes 20a. When operating the solar heat
collector 1a, cool water flows in from one end of the heat
exchanger 10a, and then passes through the heat pipes 30a and takes
out the heat of the heat pipes 30a, and finally flows out from the
other end of the heat exchanger 10a.
[0006] When assembling the solar heat collector 1a, a plurality of
openings 11a are needed to be formed on the heat exchanger 10a.
Then, the branch tubes 20a are welded into the openings 11a.
Finally, conductive material 40a is coated on the inner surface of
the branch tubes 20a, so as to tightly connect the heat pipes 30a
in the openings 11a.
[0007] However, the assembling method of the above solar heat
collector 1a is complicated and wastes a lot of time. Besides, the
heat of the heat pipes 30a is not directly exchanged to the water
in the heat exchanger 10a, but transferred through the branch tube
20a to the heat exchanger 10a. Thus, the heat transferring thereof
is less efficiency and needs to be improved.
[0008] Accordingly, in order to achieve the above objective, the
inventor comprehensive studies and uses appropriate theories to
provide the present invention, which is reasonable designed and
capable of improving the above problem.
SUMMARY OF THE INVENTION
[0009] The objective of the present invention is to provide a solar
heat collector, capable of simplifying the assembling method
thereof and improving the of heat collecting efficiency.
[0010] For achieving the above objective, the present invention

shell. The outer surface of the shell has an opening recess not
passing through the shell. The inner surface of the opening recess
has a plurality of first screw threads. The opening recess has at
least one through hole connecting to the accommodating space. The
connecting barrel includes a pipe tube having a tunnel. The pipe
tube has a plurality of second screw threads for threadedly
connecting with the opening recess. The heat pipe includes a main
body and a working fluid disposed in the main body. An end of the
heat pipe is inserted through the tunnel and the through hole and
located in the accommodating space, wherein cool water flowing into
the heat exchanger takes away the heat of the heat pipe and the
heat exchange process of the heat pipe proceeds by the phase change
of working fluid.
[0011] For achieving another objective, the present invention
provides a solar heat collector having heat pipe, including heat
collecting plate for fixedly mounting the heat pipe. The heat
receiving area of the solar heat collector can be increased and
thus improves the heat collecting efficiency.
[0012] For achieving another objective, the present invention
provides a solar heat collector having heat pipe, including a
sealing ring arranged between the opening recess of the heat
exchanger and the pipe tube of the connecting barrel. It forms a
hermetic seal between the opening recess and the pipe tube. The
connecting barrel is tightly connected to the heat exchanger.
[0013] For achieving another objective, the present invention
provides a solar heat collector having heat pipe, including a
chamfer formed on the opening recess or the pipe tube of the
connecting barrel. The sealing ring can be compressed toward the
heat pipe. The connecting barrel is tightly connected in the
opening recess. It forms a hermetic seal between the opening recess
and the pipe tube.
[0014] In comparison to the prior art, the solar heat collector of
the invention provides a opening recess on the shell of the heat
exchanger, and screw threads on the inner surface of the opening
recess. The connecting barrel can be threadedly connected to the
opening recess. An end of the heat pipe can be inserted into the
heat exchanger through the connecting barrel. Therefore, the
connection of the heat pipe can be simplified. Besides, in
comparison to the conventional heat conduction that the heat has to
transfer through the branch tube, the heat pipe of the invention
directly contacts with the water in the heat exchanger, so the
conductive efficiency is higher and the collective efficiency is
better, which both increase the practicability of the
invention.

DETAILED DESCRIPTION OF THE INVENTION
[0024] A detailed description of the present invention will be made
with reference to the accompanying drawings.
[0025] FIG. 3 is a perspective view showing a solar heat collector
having heat pipe of the present invention. The solar heat collector
1 includes a heating collecting frame 10, a heat exchanger 20, a
connecting barrel 30, at least one heat pipe 40 and at least one
heat collecting plate 50.
[0026] In this embodiment, the heat collecting frame 10 is of
triangle shaped, but not limited thereto. The heat exchanger 20 and
the heat pipe 40 are fixedly mounted on the heat collecting frame
10. The heat exchanger 20 is arranged on the upper side of the heat
collecting frame 10.
[0027] FIG. 4, FIG. 5 and FIG. 6 are respectively an exploded view,
a perspective view and a cross sectional view of the solar heat
collector of the present invention. The heat exchanger 20 has a
shell 21 and an accommodating space 200 surrounded by the shell 21.
The outer surface of the shell 21 has an opening recess 22 which
does not pass through the shell 21. The inner surface of the
opening recess 21 has a plurality of first screw threads 23. The
opening recess 21 has at least one through hole 220 connecting to
the accommodating space 200. The through hole 220 is located at the
center of the opening recess 22. The diameter of the through hole
220 is slightly larger than the diameter of the heat pipe 40.
[0028] The connecting barrel 30 includes a pipe tube 31 having a
tunnel 300 and a rotatable head 32 connecting to the pipe tube 31.
The tunnel 300 is located at the center of the pipe tube 31 and the
rotatable head 32. The tunnel 300 passes through the pipe tube 31
and the rotatable head 32. The diameter of the tunnel 300 is
slightly larger than the diameter of the heat pipe 40. The pipe
tube 31 has a chamfer 311 at the peripheral of the tunnel 300. The
chamfer 311 is oblique from the inner surface of the pipe tube 31
to the outer surface of the pipe tube 31. The outer surface of the
pipe tube 31 has a plurality of second screw threads 33 for
threadedly connecting with the first screw threads 23 of the
opening recess 22. Thus, the pipe tube 31 of the connecting barrel
30 can be threadedly connected to the opening recess 22. In
practical use, the first screw threads 23 are inner screw threads
and the second screw threads 33 are outer screw threads.
[0029] As FIG. 6 shows, the heat pipe 40 includes a main body 41
and a working fluid 42 disposed in the main body 41. An end of the
heat pipe 40 is inserted through the tunnel 300 and the through
hole 220 and located in the accommodating space 200. In this
embodiment, the heat pipe 40 is fixedly mounted on the heat
collecting plate 50 (as shown in FIG. 3). The heat received by the
heat collecting plate 50 can be transferred to the heat pipe 40.
Thus, the heat receiving area of the solar heat collector 1 can be
increased and thus improves the heat collecting efficiency.
[0030] Furthermore, the heat collector 1 may further includes a
sealing ring 60 arranged between the opening recess 22 and the pipe
tube 31. The thickness of the sealing ring 60 is slightly larger
than the chamfer 311 of the pipe tube 31. In this embodiment, the
inner diameter of the sealing ring 60 is substantially equal to the
diameter of the heat pipe 40. While assembling, the sealing ring 60
is arranged around the heat pipe 40, and then the heat pipe 40 with
the sealing ring 60 is arranged into the connecting barrel 30. The
rotatable head 32 can be rotated to drive the first screw thread 23
with the sealing ring 60 into the second screw thread 33. When
approaching the bottom of the opening recess 22, the sealing ring
60 is compressed toward the heat pipe 40 by the chamfer 311. It
forms a hermetic seal between the opening recess 22 and the pipe
tube 31. In this time, the connecting barrel 30 is tightly
connected in the opening recess 22 of the heat exchanger 20.
[0031] FIG. 7 is a schematic view of the solar heat collector of
the present invention. As shown in FIG. 3 and FIG. 7, the heat
exchanger 20 has a water inlet 202 and a water outlet 201 opposite
to the water inlet 202. Cool water flows into the heat exchanger 20
from the water inlet 202 and then passes through the heat pipe 40.
Water passing through the heat pipe 40 takes away the heat of the
heat pipe 40 and flows out from the water outlet 201. Therefore,
the heat exchange process of the heat pipe 40 proceeds by the phase
change of working fluid 42, and the purpose of heat collection of
the solar heat collector 1 is achieved.
[0032] FIG. 8 and FIG. 9 show a connecting barrel of the second
embodiment of the present invention. The connecting barrel is
substantially the same as that of the first embodiment. The heat
exchanger 20 has an opening recess 22 not passing through the shell
21. The inner surface of the opening recess 22 has a plurality of
first screw threads 23. The opening recess 22 has at least one
through hole 220 connecting to the accommodating space 200.
Further, the connecting barrel 30 includes a pipe tube 31 and a
rotatable head 32 connecting to the pipe tube 31. The difference
between this embodiment and the first embodiment is that the pipe
tube 31 does have any chamfer.
[0033] In this embodiment, the opening recess 22 has an inner
chamfer 221 oblique formed from the bottom side of the opening
recess 22 toward the accommodating space 200. When the connecting
barrel 30 is driven to the bottom of the opening recess 22, the
sealing ring 60 is compressed toward the heat pipe 40 by the pipe
tube 31. The connecting barrel 30 is tightly connected in the
opening recess 22. It forms a hermetic seal between the opening
recess 22 and the pipe tube 31.
[0034] Although the present invention has been described with
reference to the foregoing preferred embodiments, it will be
understood that the invention is not limited to the details
thereof. Various equivalent variations and modifications can still
occur to those skilled in this art in view of the teachings of the
present invention. Thus, all such variations and equivalent
modifications are also embraced within the scope of the invention
as defined in the appended claims.
