Photoenergy heat collector
A photoenergy heat collector including an outer sleeve and multiple condenser lenses. The outer sleeve has a wall formed with multiple perforations passing through the wall of the outer sleeve from inner side to outer side. The condenser lenses are respectively inlaid in the perforations to focus light beams into the outer sleeve. A water flow can go into one end of the outer sleeve and flow through the outer sleeve and then flow out from the other end of the outer sleeve. Accordingly, as a heat exchanger, the heat of the light beams focused by the condenser lenses into the outer sleeve is absorbed by the water to heat the water. The photoenergy heat collector further includes an inner sleeve disposed in the outer sleeve and extending through the outer sleeve to serve as a passage for the water flow. The focuses of the condenser lenses reside in the outer circumference of the inner sleeve, whereby the inner sleeve can absorb the heat of the light focused by the condenser lenses and transfer the heat to the water flow.
The present invention is related to a heat exchanger, and more particularly to a heat-exchanging structure capable of collecting photoenergy for heat exchange.
The conventional solar heat collectors substantially include flat plate type, heat pipe type and vacuum tube type. Most of these heat collectors are civilly used for heat exchange and applied to water heaters. Such heat collectors are able to heat the water to a temperature within about 70° C.˜100° C. or even over 100° C. In the conventional solar heat collectors, the flat plate type heat collectors pertain to those heat collectors with larger volume and heavy weight and hard to assemble/disassemble. These heat collectors not only are used in civil fields, but also applied to industrial fields.
In order to more effectively and fully collect solar energy, a parabolic light reflector is added to the heat collector. In addition, the heat collector is further equipped with a solar tracker for driving the solar heat collector to effectively aim at the sun. It is therefore tried by the applicant to provide a lightweight and high-efficiency solar heat collector.
SUMMARY OF THE INVENTIONIt is therefore a primary object of the present invention to provide a photoenergy heat collector which has better photoenergy-gathering capability.
It is a further object of the present invention to provide the above photoenergy heat collector which is able to heat water flow to higher temperature.
According to the above objects, the photoenergy heat collector of the present invention includes an outer sleeve and multiple condenser lenses. The outer sleeve has a wall formed with multiple perforations passing through the wall of the outer sleeve from inner side to outer side. The condenser lenses are respectively inlaid in the perforations to focus light beams into the outer sleeve. The photoenergy heat collector further includes an inner sleeve disposed in the outer sleeve and extending through the outer sleeve to serve as a passage for a water flow.
The present invention can be best understood through the following description and accompanying drawings wherein:
Please refer to
The outer sleeve 12 is a circular hollow tube body. The wall of the outer sleeve 12 is formed with multiple perforations 22 passing through the wall of the outer sleeve 12 from inner side to outer side.
The condenser lenses 14 are respectively inlaid in the perforations 22 to focus sunlight or the light coming from artificial light sources into the outer sleeve 12.
According to the above arrangement, a water flow can go into one end of the outer sleeve 12 (as shown by the arrow) and flow through the outer sleeve 12 and then flow out from the other end of the outer sleeve 12. Accordingly, as a heat exchanger, the heat of the light focused by the condenser lenses 14 into the outer sleeve 12 is absorbed by the water to heat the water.

In the above embodiments of the present invention, the condenser lenses 14 are aspherical glass lenses which have better light-gathering capability.
According to the above arrangement, the photoenergy heat collector 1 of the present invention has the following advantages:
-
- 1. By means of multiple condenser lenses 14, the water flow can be heated to over several hundred-degree Celsius.
- 2. The outer sleeve 12 and the inner sleeve 16 can be rotated relative to each other. Therefore, the focuses of the condenser lenses 14 are movably positioned on the outer circumference of the inner sleeve 16. This can achieve higher heat-exchanging efficiency.
The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
