Description
- 1. Field of the Invention
- The invention relates to a heat collecting device, more particularly to a heat collecting device that has enhanced heat collecting and retaining effects.
- 2. Description of the Related Art
- With the gradual depletion of natural resources on this planet, the concept of energy conservation is extensively promoted and applied.
- In existing vacuum heat collectors, heat is absorbed by an outer portion of a vacuum heat collector and is collected in a vacuum chamber. As the flowability of fluid under vacuum is low, the heat energy can be conserved to achieve the purpose of vacuum heat collection.
- However, a conventional vacuum heat collector, such as the solar energy collecting device disclosed in US Patent Application Publication No. 2003/0230300 A1, has a single layer structure, which does not provide ideal heat collection so that subsequent heat conduction is not satisfactory. As such, the intended effect of recycling the collected heat energy cannot be fully achieved.
- Therefore, the object of the present invention is to provide a heat collecting device that has enhanced heat collecting and retaining effects.
- Accordingly, a heat collecting device of this invention includes: a first vacuum device which includes a first housing and which defines a first vacuum chamber; a second vacuum device which includes a second housing that contains the first vacuum device and which cooperates with the first vacuum device to define a second vacuum chamber therebetween; a metal plate mounted within the first vacuum device and having a plate body and an extension portion extending from the plate body to project outwardly of the first and second vacuum devices, the metal plate being capable of absorbing heat energy from an external heat source through the first and second vacuum devices; an insulating layer enclosing the extension portion of the metal plate; and a thermoelectric semiconductor device attached to the extension portion of the metal plate, extending through the insulating layer and disposed outside the second vacuum device for conducting the heat energy absorbed by the metal plate.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawing, of which:
-
FIG. 1 is a sectional view to illustrate the preferred embodiment of a heat collecting device according to the invention. - Referring to
FIG. 1 , the preferred embodiment of a heat collecting device according to the present invention is shown to include afirst vacuum device 1, asecond vacuum device 2, ametal plate 3, an insulating layer 4, and athermoelectric semiconductor device 5. - The
first vacuum device 1 includes a rectangular first housing which defines afirst vacuum chamber 10. One of thewalls 11 of the first housing is formed from a glass material. Theother walls wall 12 is formed with anopening 121. - The
second vacuum device 2 includes a rectangular second housing that contains thefirst vacuum device 1, and cooperates with thefirst vacuum device 1 to define asecond vacuum chamber 20 therebetween. One of thewalls 21 of the second housing confronts thewall 11 of the first housing, and is formed from a reinforced glass material. Theother walls wall 22 is formed with anopening 221 aligned with theopening 121 in the first housing. - The
metal plate 3 is formed from a conductive metal material, such as copper and aluminum, and is mounted within thefirst vacuum device 1. Themetal plate 3 has aplate body 31 and anextension portion 32 that extends from theplate body 31 and through theopenings metal plate 3 is coated with ablack paint material 33 to enhance heat collection and conduction of heat energy. - The insulating layer 4 is formed from a plastic material, and is disposed to enclose sealingly the
extension portion 32 of themetal plate 3. - The
thermoelectric semiconductor device 5 is attached to theextension portion 32 of themetal plate 3, and extends through ahole 41 formed in the insulating layer 4, and is disposed outside thesecond vacuum device 2. Thethermoelectric semiconductor device 5 has a heat-collectingside 51 attached to theextension portion 32 of themetal plate 3, and a heat-radiatingside 52 opposite to the heat-collectingside 51. The heat-collectingside 51 absorbs the heat energy collected by themetal plate 3, whereas the heat-radiatingside 52 conducts the absorbed energy to the outside. In this embodiment, thethermoelectric semiconductor device 5 is a highly efficient, high-performance thermoelectric cooling unit. Since the construction of thethermoelectric semiconductor device 5 is not the crux of this invention, it will not be described in detail herein for the sake of brevity. - In use, the
plate body 31 of themetal plate 3 absorbs heat energy from anenergy source 100 through theglass walls second vacuum devices plate body 31 of themetal plate 3 rises, and the heat is conducted to theextension portion 32. Thethermoelectric semiconductor device 5 attached to theextension portion 32 of themetal plate 3 senses the heat energy accumulated on themetal plate 3, and conducts the heat energy outward from the heat-radiatingside 52. By attaching the heat-radiatingside 52 to a water storage device (not shown) of a water heater, water in the water storage device will be heated, thereby forming a water heating device. - Since the heat collecting device of this invention utilizes the first and
second vacuum devices second vacuum chambers vacuum chambers black paint material 33 on themetal plate 3 that has heat collecting and conducting effects, the heat energy in the first andsecond vacuum chambers thermoelectric semiconductor device 5. - Regarding the supply of the
energy source 100, sunlight exposure or sunlight focusing can be employed. For sunlight exposure, a temperature as high as about 350° C. can be reached. For sunlight focusing, a temperature as high as about 600° C. can be reached. - In sum, compared with the conventional vacuum heat collector which does not have a satisfactory heat collecting effect, the present invention provides a double vacuum chamber structure that can collect heat energy via the
metal plate 3 and that can better retain the heat energy in the first andsecond vacuum chambers metal plate 3 can be maintained at a high level and so that the heat energy thus collected will not easily dissipate to the surrounding. The provision of theblack paint material 33 on the outer surface of themetal plate 3 further enhances the heat collecting and conducting effects. - While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
