Abstract
Abstract This invention relates to a combined solar electricity generation and cooling system and more particularly phase change inhibited materials are utilized for improving the efficiency and life of solar panels. The system uses phase change inhibited materials based fluids which is sealed in channels on the back side of solar panels. Owing to the ultra-high thermal conductivity of phase change inhibited material, the heat from the solar panel can be dissipated to the air, thus significantly improves the energy conversion efficiency and also the life time of the solar panel.

Description
Phase Change Inhibited Materials for Solar Panel Cooling
Technical Field of the Invention:
This invention is related to a solar panel cooling system and more particularly a phase change inhibited materials attached to solar panels for improving the efficiency and life time of solar panels.
Background of the Invention:
The solar panel (or solar cell) directly converts the incident solar irradiance to electricity. The most efficient, sustainable, and eco-friendly systems are the solar panel modules which convert small part of the solar irradiance to electricity. The remaining part of the solar irradiation then converts into heat, which increases the temperature of the cells and reduces the performance of the solar panel. It has been shown that the overall efficiency of solar panel drops drastically with an increase in temperature. Therefore, it is essential to develop effective cooling systems for photovoltaic panels which can significantly improve the lifetime and efficiency.
Cooling techniques for heat applications were proposed early on in solar panel exploitation. The main advantage of cooling is evident: higher electrical output. However, cooling requires a separate system which will remove heat to some extent. The construction and maintenance of that system can be expensive and there is a possibility that the cost of system maintenance could outweigh the benefits of the improved electrical yield. For example, the water cooling systems needs pump and a lot of water resources, which is undesired in desert area and on the roof. Therefore, a cost-effective and high performance cooling system needs to be developed.
The invention provides a cooling of the solar panel by means of a new phase inhibited material which has unique advantages of ultra-high heat transfer rate without using any pump or gravity to drive the liquid flow. More importantly, different shapes of the cooling panel can be designed, which is compatible with different type of solar panels.
Object of the Invention
The present invention is related to a cooling material that is intended to provide cooling of solar panels that is based on the circulation of liquid phase change inhibited material, and which is intended to self-regulate the circulation of the cooled fluid in a simplified manner without the need to incorporate elements special.
2020100650 28 Apr 2020
In general, the invention is applicable in the sector of the renewable energy industry, but it can also be applied in any sector in which it is required to perform the cooling of components.
Description of the Invention
In order to achieve the goals and solve the above challenges, the invention provides a new solar panel cooling device that has the particularity of comprising a phase change inhibited materials on the back of solar panels, which can quickly remove the heat generated from the sun irradiation. Phase change inhibited materials have unique advantages of high specific heat transfer density of 10-1000W/cm2, ultra-high coefficient of thermal conductivity at 6000W/(m-K) without using any pump or gravity to drive the liquid flow.
In the preferred embodiment of the invention, the phase change inhibited material is sealed on the back side of the solar panel, so that it has close contact with the back side of photovoltaic panel, which produces the photovoltaic panel cooling.
The cooling circuit is composed of phase change inhibited materials, which are arranged along the area of tunnel area in which said coolant is applied. The cooling circuit comprises a pipe located in the area of tunnel through which the cooling liquid flows. Said pipe is connected to the return line of the cooling circuit, which these conventionally incorporate.
In addition, the cooling circuit does not need a cooling radiator or pump which can greatly simplify the cooling device architecture.
In the preferred embodiment of the invention, the phase change inhibited material is sealed in previously made tunnels on supporting tunnels.
In addition, in the preferred embodiment of the invention the phase change inhibited material is in contact with the surface of the back face of solar panel and covered by a shell of a material that prevents the evaporation of phase change inhibited material.
The invention also provides that phase change inhibited material can be completely covered by the envelope of material that prevents the evacuation of phase change inhibited material and that includes an inlet and an outlet thereof, so that the phase change inhibited material is attached to the rear face of the panel by interposing said envelope. The envelope of material can also prevent the short circuit among solar cells.
2020100650 28 Apr 2020
In the preferred embodiment of the invention, the envelope is made of plastic material, but it can obviously be made of any other material that performs the function mentioned to prevent the phase change inhibited material from evaporating when it runs along the tunnel.
The described configuration provides a very simple and economical device that performs the self-regulation of the circulation of the cooling material and all this without the need for the incorporation of special elements such as cooling irradiators.
In order to facilitate a better understanding of this descriptive report, and being an integral part thereof, Figure 1 is attached in which the object of the invention has been shown as an illustrative and non-limiting nature.
Description of the Drawing:
Figure 1 is a schematic drawing of the operation of a solar panel combined with phase change inhibited materials based cooling panel system. The phase change inhibited materials are sealed on the back of the solar panels in different ways. As shown in Figure 1 b, the cooling panels can be the same size as solar cells, e.g. 6 inch, this design can fit different size of solar panels and also avoid possible short circuit of the solar panels. In this design, the cooling panels with sealed phase change inhibited materials are attached to solar cells. In Figure 1 c, the whole solar panel is attached on the surface of phase change inhibited cooling panels which provide supervisor cooling efficiency. Figure 1 d and e show the top and bottom view of a phase change inhibited materials based cooling panel.
