Description

Technical Field

[0001] The utility model relates to the technical field of photothermal and photovoltaic integration, and in particular to a photothermal and photovoltaic integrated board with a filtering function. Background Art

[0002] PVT photovoltaic and thermal integrated technology is a method of comprehensive utilization of solar energy. PVT refers to the combination of photovoltaic (Photovoltaic) and thermal (Thermal). Photovoltaic technology converts solar radiation into electrical energy, while thermal technology converts solar radiation into thermal energy. PVT integrated technology combines these two methods to achieve dual utilization of solar energy, playing an important role in many fields and providing us with clean and renewable energy.

[0003] PVT photovoltaic and thermal integration technology has many application areas. In the field of construction, PVT modules can be installed on the exterior walls, roofs and other locations of buildings to generate electricity through photovoltaic power generation, while using solar heat to generate hot water for heating or drive refrigeration equipment. This can not only meet the energy needs of buildings, but also reduce dependence on traditional energy and achieve the goal of energy conservation and emission reduction.

[0004] In the agricultural field, PVT photovoltaic and thermal integration technology can be applied to greenhouse cultivation. PVT modules can be covered on the top of the greenhouse, absorbing solar radiation to generate electricity, and using light to generate warm air for the growth of plants in the greenhouse. This can not only increase the temperature of the greenhouse environment, but also reduce energy costs and increase the yield and quality of crops.

[0005] In addition, PVT photovoltaic and thermal integration technology can also be applied to solar water heaters, solar refrigeration and other fields. By combining photovoltaic and thermal technologies, solar energy resources can be utilized to the maximum extent and sustainable use of energy can be achieved.

[0006] Some existing photovoltaic and thermal integrated devices are not equipped with corresponding filtering structures when in use, and are unable to filter the water entering and leaving the pipes. Impurities and foreign objects in the water are easily attached to the inner wall of the pipes, which can easily cause pipe blockage.

[0007] For example, a photovoltaic-thermal integrated device disclosed in announcement number CN108768294A is connected to a water tank through a hot and cold regulating flow channel, which maintains the photovoltaic panel at a suitable temperature (about 25°) for higher photoelectric conversion. When the temperature of the photovoltaic panel is too high, the hot and cold regulating flow channel transfers the heat to the water tank through the cooling pipe. While the water tank produces hot water, it ensures a rapid and lasting cooling effect on the photovoltaic panel, effectively protecting the service life of the photovoltaic panel.

[0008] However, the cooling pipe in the water tank of the patent is not provided with a corresponding filtering structure, and the water in and out of the pipe cannot be filtered. Impurities and foreign objects in the water are easy to adhere to the inner wall of the pipe, which can easily cause the pipe to be blocked.

[0009] Therefore, it is necessary to invent a photothermal photovoltaic integrated panel with filtering function to solve the above problems. Utility Model Content

[0013] Preferably, the duct frame is arranged between the absorption panel and the backing plate, the absorption panel is installed on the front side of the duct frame, and the backing plate is installed on the back side of the duct frame.

[0015] Preferably, the absorption panel is an aluminum plate plated with a black chrome coating, and a plurality of solar cells are mounted on the surface of the absorption panel, and the plurality of solar cells are distributed in a rectangular array.

[0017] Preferably, a plurality of heat-conducting plates are fixedly connected to the back of the absorption panel, and a card slot is provided on the surface of the heat-conducting plate, and the circulation channel is card-connected with the card slot.

[0018] The heat absorbed by the absorption panel is conducted to the circulation channel through the heat conduction plate.

[0019] Preferably, the plurality of heat conducting plates are distributed in a linear array, the circulation channel is made of copper material, and the circulation channel is bent up and down reciprocatingly inside the pipeline frame.

[0020] As water flows through the circulation channel, it continuously absorbs heat conducted from the circulation channel, thereby increasing its temperature.

[0021] Preferably, the front side of the pipeline frame is filled with a No. 1 aluminum-plated reflective film, the number of the No. 1 aluminum-plated reflective film is set to two, and the two No. 1 aluminum-plated reflective films respectively cover the upper and lower bends of the circulation channel.

[0022] A No. 1 aluminum-plated reflective film is used to cover the bending parts of the circulation channel that are not in contact with the heat conductive plate to prevent heat from being dissipated from the bending parts.

[0023] Preferably, the back of the pipeline frame is filled with a No. 2 aluminum-plated reflective film, and the aluminum-plated surfaces of the No. 1 aluminum-plated reflective film and the No. 2 aluminum-plated reflective film are both arranged toward the circulation flow channel.

[0024] The entire back side of the circulation channel is covered by a No. 2 aluminum-plated reflective film to further prevent the heat of the circulation channel from being lost to the outside.

[0025] Preferably, the number of the limiting buckles is set to two, one of which is arranged close to the top end of the filter, and the other of which is arranged close to the bottom end of the filter.

[0026] The filter can be limited at both ends by the upper and lower limit buckles, thereby providing a better limit and fixation effect.

[0027] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0028] 1.

[0029] 2. By filling the front and back of the pipe frame with No. 1 aluminum-plated reflective film and No. 2 aluminum-plated reflective film, the heat emitted by the circulation channel is reflected by the aluminum-plated surface, so that the heat can be concentrated together, thereby improving the heating efficiency of the water inside the circulation channel.
