- 1. Field of the Invention
- The invention relates to a solar energy collecting device, more particularly to a solar energy collecting device with a thermal conductor.
- 2. Description of the Related Art
- FIG. 1 illustrates a conventional
water heating apparatus 1 that includes abase frame 11, awater tank 12 mounted on one side of thebase frame 11 and having awater inlet 121 and awater outlet 122, and a plurality of heat-absorbingpipes 13 disposed inclinedly between thewater tank 12 and the other side of thebase frame 11. Each heat-absorbingpipe 13 has a connectingend 131 connected to and in fluid communication with thewater tank 12, and a closedend 132 opposite to the connectingend 131 and disposed lower than the connectingend 131. When the heat-absorbingpipes 13 are irradiated by solar radiation (as indicated by arrows in FIG. 2), due to the reason that cool water has a specific gravity larger than that of hot water, heating circulation is thus possible by virtue of the downwardly flowing cool water and upwardly flowing hot water. - The following are some of the drawbacks of the conventional water heating apparatus1:
- 1. Each heat-absorbing
pipe 13 has a curved heat-absorbing surface that reflects solar radiation, thereby resulting in an inferior heat-absorbing efficiency. - 2. As the cool and hot water flow in opposite directions in the
pipes 13, a great amount of heat loss can occur during thermal conduction. - 3. Since scales are easily generated in the heat-absorbing
pipes 13, in order to maintain better heat-conducting efficiency, periodic cleaning and maintenance are required. - Therefore, the object of the present invention is to provide a solar energy collecting device with a thermal conductor and a water heating apparatus using the solar energy collecting device.
- According to one aspect of the present invention, a solar energy collecting device comprises:
- a housing confining a receiving space and formed with an opening for access into the receiving space, the housing having a transparent side wall; and
- a thermal conductor having a heat-absorbing portion disposed in the receiving space of the housing and a heat-radiating portion extending out of the receiving space via the opening, the thermal conductor including a hollow heat-conducting member that defines a sealed chamber therein and that is formed with a thermal conductor layer in the chamber, the heat-absorbing portion absorbing solar energy when the housing is irradiated by solar radiation and transmitting the solar energy to the heat-radiating portion.
- According to another aspect of the present invention, a water heating apparatus comprises:
- a water tank having a water inlet and a water outlet; and
- a solar energy collecting device including
- a housing confining a receiving space and formed with an opening for access into the receiving space, the housing having a transparent side wall, and
- a thermal conductor having a heat-absorbing portion disposed in the receiving space of the housing and a heat-radiating portion extending out of the receiving space via the opening and into the water tank, the thermal conductor including a hollow heat-conducting member that defines a sealed chamber therein and that is formed with a thermal conductor layer in the chamber, the heat-absorbing portion absorbing solar energy when the housing is irradiated by solar radiation and transmitting the solar energy to the heat-radiating portion for heating water in the water tank.

Thethermal conductor 4 includes a hollow heat-conductingmember 41, which is a rectangular member, that defines a sealedchamber 411 therein and that is formed with athermal conductor layer 42 in the chamber 411 (see FIG. 5).

It is noted that the heat-absorbingfilm 5 is preferably formed by magnetically controlled sputtering. - The heat-absorbing
portion 412 of thethermal conductor 4 absorbs solar energy when thehousing 3 is irradiated by solar radiation, and then transmits the solar energy to the heat-radiatingportion 413 for heating water in thewater tank 6. - FIGS. 6 and 7 illustrate a solar energy collecting device of the second preferred embodiment of a water heating apparatus according to the present invention, which is a modification of the first preferred embodiment. Unlike the previous embodiment, the
housing 3′ includes abase body 7, and atransparent cover 8 mounted on thebase body 7. Thebase body 7 and thetransparent cover 8 confine thereceiving space 73. Thetransparent cover 8 is made of reinforced glass or heat-resistant transparent plastic. - The following are some of the advantages attributed to the water heating apparatus of the present invention:
