Benefits of technology

[0007]Therefore, an object of the present invention is to provide a portable solar energy collecting device that can overcome the aforesaid drawbacks of the prior art.

Problems solved by technology

When the thermal energy is generated from solar energy or terrestrial heat, unstable supply of the thermal energy to the first pneumatic cylinder 11 may occur.
When the thermal energy is generated by fuel combustion, in order to ensure stable supply of the thermal energy to the first pneumatic cylinder 11, continuous supply of fuel is necessary, thereby resulting in relatively high costs.

Embodiment Construction

[0015]Referring to FIGS. 2 and 3, the preferred embodiment of a portable solar energy collecting device according to the present invention is shown to include a container 3, and a heat absorbing unit 4.

[0016]The container 3 is configured with an accommodating space 30 therein. In this embodiment, the container 3 includes a transparent housing 31 and a cap body 32.

[0017]The housing 31 includes an inner surrounding wall 313, and an outer surrounding wall 311, and is formed with a vacuum chamber 33 defined between the inner and outer surrounding walls 313, 311 and surrounding the accommodating space 30. The housing 31 further includes a partition wall 312 disposed in the vacuum chamber 33 so that the vacuum chamber 33 is divided by the partition wall 312 into first and second chamber portions 331, 332. The housing 31 is further formed with an opening 310. In this embodiment, the housing 31 is made of a heat-isolating material, such as glass and quartz.

[0018]The cap body 32 covers seali...

Abstract

A portable solar energy collecting device includes a container configured with an accommodating space therein and including a transparent housing. The transparent housing is formed with a vacuum chamber defined between the inner and outer surrounding walls and surrounding the accommodating space. A heat-absorbing unit is disposed in the accommodating space in the container, absorbs solar energy when the housing is irradiated by solar radiation, and converts the solar energy into thermal energy that is accumulated in the accommodating space in the container.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority of Taiwanese Application No. 098139494, filed on Nov. 20, 2009.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a thermal collecting device, more particularly to a portable solar energy collecting device.[0004]2. Description of the Related Art[0005]FIG. 1 illustrates a conventional thermal engine 1 disclosed in U.S. Pat. No. 6,779,341 and including a first pneumatic cylinder 11, a second pneumatic cylinder 12, a fluid pipe 15 intercommunicating fluidly the first and second pneumatic cylinders 11, 12, and a flywheel assembly 13 coupled to the first and second pneumatic cylinders 11, 12. Thermal energy from a thermal energy source 2 is applied to a cylinder body 111 of the first pneumatic cylinder 11 to result in an expansion stroke of the first pneumatic cylinder 11 and in rotation of the flywheel assembly 13. The expansion stroke of the first pneumatic cylinder 11 als...
