[0037] Hereinbelow, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings, the same reference numerals will be used throughout the drawings and the description to refer to the same or like elements or parts, and a detailed description of those elements will be omitted.

[0038] In the following description, when the functions of conventional elements and the detailed description of elements related with the present disclosure may make the gist of the present disclosure unclear, a detailed description of those elements will be omitted.

[0039] An entire system including a complex energy generation device using sunlight and solar heat (hereinbelow, the device will refer to ‘complex energy generation device’) according to an embodiment of the present disclosure includes a heat storage tank 1, a heating tube 2, a transfer tube 3, and a complex energy generation device 100, 200, 300, as shown in FIG. 1.

[0040] The heat storage tank 1 is a water reservoir having a predetermined inside space, and an upper portion thereof is connected to a supply port to be supplied with domestic water and a lower portion thereof is connected to a discharge port to discharge hot water.

[0041] The heating tube 2 is provided to heat the domestic water in the heat storage tank 1 to generate hot water. The heating tube 2 may be arranged in a zigzag array in the heat storage tank 1.

[0042] The transfer tube 3 is a tube connecting a first side portion of the complex energy generation device to the heating tube 2. The transfer tube 3 allows heat medium oil that has passed through the complex energy generation device and the heating tube 2 to flow into the complex energy generation device again, so that the heat medium oil is circulated.

[0043] Meanwhile, the complex energy generation device is a device configured to perform both power generation using sunlight and water heating using solar heat. Hereinbelow, the complex energy generation device will be described in detail with reference to accompanying drawings.

[0044] As shown in FIG. 1, the complex energy generation device includes a heat storage tube 100, a solar panel 200, and a heat radiation panel 300.

[0045] The heat storage tube 100 has an inlet portion 101 at a first side portion thereof to receive the heat medium oil and an outlet portion 103 at a second side portion thereof to discharge the heat medium oil.

[0046] As shown in FIG. 1, the first side portion of the heat storage tube 100 is connected to the transfer tube 3 and the second side portion of the heat storage tube 100 is connected to the heating tube 2. The heat medium oil flowing into the heat storage tube 100 through the transfer tube 3 performs heat-exchange and then is discharged into the heating tube 2.

[0047] A lower surface of the heat storage tube 100 has a slit 100S formed in a longitudinal direction thereof. An upper portion of the heat radiation panel 300 is inserted into the slit 100S.

[0048] In the structure of the heat storage tube 100 as described above, the heat medium oil may perform heat-exchange while circulated into the heat storage tube 100 and being brought into contact with the heat radiation panel 300.

[0049] The solar panel 200 has a plurality of solar cells 201 performing power generation using sunlight. Specifically, the solar cells 201 are provided on a front surface of the solar panel 200, as shown in FIG. 3. A transparent protective glass 210 may be laminated on the front surface of the solar panel 200.

[0050] The solar cells 201 provided on the solar panel 200 are an element generating energy using sunlight, and are configured to supply generated electric energy to the outside through a separate electric wiring (not shown) or to store the generated electric energy in a battery.

[0051] The heat radiation panel 300 has the upper portion that is inserted into the heat storage tube 100 through the slit 100S of the heat storage tube 100 while sealing the slit 100S and a lower portion that is laminated on a rear surface of the solar panel 200.

[0052] When the solar panel 200 receives sunlight, the temperature of the solar panel 200 gradually is increased. When the temperature of the solar panel 200 is increased above a predetermined temperature, efficiency of energy generation may be reduced.

[0053] The heat radiation panel 300 serves to prevent the temperature of the solar panel 200 from being increased above the predetermined temperature.

[0054] The form of the slit 100S and the sectional form of the heat radiation panel 300 are formed identically. Accordingly, the slit 100S may be sealed when the upper portion of the heat radiation panel 300 is inserted into the slit 100S. In order to increase a sealing force between surfaces of the slit 100S and the heat radiation panel 300, an O-ring or a separate sealing means may be provided.

[0055] As shown in FIG. 5, an upper end surface 300a of the heat radiation panel 300 inserted into the heat storage tube 100 through the slit 100S is extended to reach an inner surface of the heat storage tube 100. The upper end surface 300a of the heat radiation panel 300 is formed in a curved surface so as to be in close contact with the inner surface of the heat storage tube 100.

[0056] As shown in FIG. 6, it is preferable that a first end portion 300b and a second end portion 300c of the heat radiation panel 300 inserted into the heat storage tube 100 through the slit 100S have streamlined cross-sections, so that the heat medium oil may be efficiently circulated.

[0057] The heat radiation panel 300 is laminated to be in close contact with the rear surface of the solar panel 200 and serves to transmit heat of the solar panel 200 to the heat medium oil.

[0058] When the heat-exchange is performed between the solar panel 200 and the heat medium oil circulated in the heat storage tube 100, the temperature of the solar panel 200 is prevented from being increased above the predetermined temperature, so that the efficiency of energy generation may be maintained.

[0059] Thermal grease may be disposed between the heat radiation panel 300 and the solar panel 200, and the thermal grease may increase the efficiency of heat transfer between the heat radiation panel 300 and the solar panel 200.

[0060] The heat radiation panel 300 described above may be formed of a material with the same coefficient of thermal expansion as the heat storage tube 100 in order to prevent a gap formed between the slit 100S and the heat radiation panel 300 due to a difference in the coefficient of thermal expansion.

[0061] According to the structure of the heat radiation panel 300 as described above, the heat radiation panel 300 may be configured to prevent the temperature of the solar panel 200 from being increased above the predetermined temperature and to transmit solar heat to the heat medium oil.

[0062] As shown in FIG. 5, an exposed surface of the heat radiation panel 300 to the outside of the heat storage tube 100 may be covered by an insulation material 310.

[0063] As shown in FIGS. 7A to 7C, the thickness of the heat radiation panel 300 may vary.

[0064] For example, as shown in FIG. 7A, the heat radiation panel 300 may have a uniform thickness.

[0065] Furthermore, for example, as shown in FIG. 7B, a thickness of a first side portion of the heat radiation panel 300 corresponding to the first side portion of the heat storage tube 100 is formed thicker than a thickness of a second side portion of the heat radiation panel 300 corresponding to the second side portion of the heat storage tube 100. In other words, the thickness of the heat radiation panel 300 is formed in a multi-stepped shape, so that the thickness of the heat radiation panel 300 is thinner stepwisely as the heat radiation panel 300 goes from the first side portion to the second side portion thereof.

[0066] The slit 100S is formed in a shape corresponding to the thicknesses of the heat radiation panel 300. A contact surface of the heat radiation panel 300 in contact with the rear surface of the solar panel 200 is formed flat and an opposite surface to the contact surface is formed in the multi-stepped shape, so variation of the thickness of the heat radiation panel 300 is realized.

[0067] For example, as shown in FIG. 7C, a thickness of the first side portion of the heat radiation panel 300 corresponding to the first side portion of the heat storage tube 100 may be formed thicker than a thickness of the second side portion of the heat radiation panel 300 corresponding to the second side portion of the heat storage tube 100. In other words, the thickness of the heat radiation panel 300 may be formed gradually thinner as the heat radiation panel 300 goes from the first side portion to the second side portion thereof.

[0068] In FIG. 7C, the slit 100S is formed in a shape corresponding to the thickness of the heat radiation panel 300. The contact surface of the heat radiation panel 300 in contact with the rear surface of the solar panel 200 is formed flat, and the opposite surface to the contact surface is formed to be inclined, so the thickness of the heat radiation panel 300 is changed.

[0069] As described above, when the thickness of the first side portion of the heat radiation panel 300 corresponding to the first side portion of the heat storage tube 100 is formed thicker than the thickness of the second side portion of the heat radiation panel 300 corresponding to the second side portion of the heat storage tube 100, the heat-exchange efficiency between the heat radiation panel 300 and the heat medium oil may be increased.

[0070] The thickness shape of the heat radiation panel 300 is intended to increase a contact area with the heat medium oil flowing in the heat storage tube 100. In addition, the temperature of the heat medium oil flowing into the inlet portion 101 of the heat storage tube 100 is increased while the heat medium oil passes through the heat storage tube 100, so the heat radiation panel 300 is formed to be thicker to increase an amount of heat-exchange, in order to promote heat-exchange in the inlet portion 101 of the heat storage tube 100.

[0071] The complex energy generation device according to the described above embodiment of the present disclosure may perform both power generation using sunlight and heating water using solar heat. As the thickness variation of the heat radiation panel 300 increases a contact area between the heat radiation panel 300 and the heat medium oil, and increases the amount of heat-exchange at the inlet portion side 100a of the heat storage tube 100, the efficiency of heat-exchange is increased.

[0072] Although a preferred embodiment of the present disclosure has been described for illustrative purposes with respect to the accompanying drawings, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the present disclosure as disclosed in the accompanying claims. Therefore, the scope and spirit of the present disclosure should be interpreted by the accompanying claims disclosed with the various modifications.
