The fluid passage 200 may be provided on the entire bottom surface of the solar cell panel 100. In more detail, the fluid passage 200 may be provided on the bottom surface of the solar cell panel 100 in a zig-zag pattern. In other words, the fluid passage 200 may be provided in the curved shape on the bottom surface of the solar cell panel 100.
The fluid passage 200 has the shape of a pipe. In other words, a fluid may flow through an empty space in the fluid passage 200. In more detail, air may flow through the empty space in the fluid passage 200.
The fluid passage 200 may include plastic or metal. For example, the fluid passage 200 may include metal, such as copper (Cu) or aluminum (Al), representing high thermal conductivity.
The airflow generator 300 is provided at the end portion of the fluid passage 200. The airflow generator 300 may generate the flow of air into the fluid passage 200. The airflow generator 300 may generate the airflow through the Bernoulli’s principle.
As shown in FIGS. 2 and 3, the airflow generator 300 includes a gas inlet 310, a gas outlet 320, a peripheral part 330, and a gas injection part 340.
The gas inlet 310 is linked with the peripheral part 330. The gas inlet 310 may be curved inward from the peripheral part 330 while extending from the peripheral part 330. The gas inlet 310 is linked with the gas outlet 320. Gas is introduced into the fluid passage 200 through the gas inlet 310.
The gas inlet 310 has a diameter smaller than that of the gas outlet 320. The end portion of the gas inlet 310 may be inserted into the gas outlet 320. In addition, the gas inlet 310 may be spaced apart from the gas outlet 320.
A diameter R1 of the gas inlet 310 may be gradually reduced toward the fluid passage 200 and then gradually increased. The gas inlet 310 may have the shape of an orifice.
The gas outlet 320 is linked with the gas inlet 310. The gas outlet 320 is linked with the fluid passage 200. In more detail, the gas outlet 320 may be integrally formed with the fluid passage 200.
The gas outlet 320 has a diameter greater than that of the gas inlet 310. In addition, the gas outlet 320 may have a diameter smaller than a diameter R3 of the fluid passage 200. The gas outlet 320 may surround the end portion of the gas inlet 310. A diameter R2 of the gas outlet 320 may be gradually increased toward the fluid passage 200.
The peripheral part 330 surrounds the gas outlet 320 and the gas inlet 310. In addition, the peripheral part 330 may surround the fluid passage 200. In addition, the peripheral part 330 is spaced apart from the gas outlet 320. In addition, the peripheral part 330 may be integrally formed with the gas inlet 310.
The gas injection part 340 is a space between the gas outlet 320 and the gas inlet 310. The gas injection part 340 serves as an injection port to inject compressive gas toward the inner surface of the gas outlet 320. The gas injection part 340 is connected to a space 321 between the peripheral part 330 and the gas outlet 320.
The compressive gas generator 400 generates compressive gas. The peripheral part 330 is linked with the compressive gas generator 400 through an airline. The compressive gas is supplied between the peripheral part 330 and the gas outlet 320.
As shown in FIG. 3, the compressive gas generated from the compressive gas generator 400 is supplied to the space 321 between the peripheral part 330 and the gas outlet 320 through the air line 410. Thereafter, the compressive gas is injected toward the inner surface of the gas outlet 320 through the gas injection part 340.
In this case, since the diameter R2 of the gas outlet 320 is gradually increased toward the fluid passage 200, the low atmospheric pressure is formed in the gas outlet 320 through the injection of the compressive gas. Accordingly, air is introduced into the gas outlet 320 through the gas inlet 310.
The introduced air and the compressive gas injected from the gas injection part 340 are introduced into the fluid passage 200. Accordingly, the bottom surface of the solar cell panel 100 may be air-cooled by air introduced into the fluid passage 200.
As described above, the solar cell apparatus according to the embodiment generates the flow of coolant gas in the fluid passage 200 by using the airflow generator 300. In particular, the solar cell apparatus according to the embodiment injects compressive gas into the gas outlet 320 having a greater inner diameter to generate airflow. In other words, the solar cell apparatus according to the embodiment generates compressive gas through the Bernoulli’s principle.
Therefore, the solar cell apparatus according to the embodiment can effectively cool the solar cell panel 100 through the Bernoulli’s principle with low power consumption.
Accordingly, the solar cell apparatus according to the embodiment prevents the efficiency degradation resulting from the increase of the temperature, and can effectively convert the solar light into the electrical energy.
