Description

Technical Field

[0001] The utility model relates to the field of solar heat collecting plates, in particular to a solar heat collecting plate with enhanced flow passage circulation. Background Art

[0002] Flat-plate solar water heaters are designed and developed to match small high-rise residential buildings. The water tank is placed on balconies, roofs, walls and other places, and the solar collectors are placed on the balcony, windows, roofs and walls of the south facade of the building, which makes up for the regret that traditional solar water heaters cannot be integrated with buildings and the environment due to their inherent deficiencies. The collector and the water tank are separated from each other. The collector can be flexibly installed on the roof, skylight, balcony or wall without being restricted by position, thus achieving an integrated combination with high-rise buildings and the environment. The solar collector is composed of an outer shell, a transparent cover, a heat absorbing plate and a flow channel. The medium oil is transported to the flow channel through the input port, and then the solar energy is absorbed by the heat absorbing plate to heat the flow channel, and then the medium oil is transported to the water tank through the output pipe to heat the water inside the water tank.

[0003] For example, Chinese patent CN208859914U discloses a flat solar collector core with stainless steel flow channels, including stainless steel transverse tubes, aluminum fins, and welded aluminum sheets. The aluminum fins and stainless steel transverse tubes are provided with seven groups respectively. The aluminum fins are rectangular structures. One side of the aluminum fins is coated with a blue base film. Each stainless steel transverse tube is fixed to the side of the aluminum fin without the blue film by welded aluminum sheets. The welded aluminum sheets and the aluminum fins are matched and wrapped on the outer surface of the stainless steel transverse tubes. The two sides of the welded aluminum sheets are welded to the aluminum fins by ultrasonic brazing technology. The stainless steel transverse tubes are parallel to each other and are equidistantly spaced at both ends. The side tubes are connected by welding. The utility model adopts a stainless steel transverse tube as a flow channel tube. The cost price of stainless steel material is lower than that of copper tubes, which reduces production costs, increases the compressive strength, corrosion resistance, and temperature difference cycle frost resistance of the flow channel tube, reduces the difference in expansion coefficient between the flow channel tube and the aluminum fins, and increases the service life of the flow channel welding joints. However, the following deficiencies still exist.

[0004] Although the existing technology has improved the service life of the flow channel of the solar collector panel, it is unable to improve the flow circulation of the flow channel and control the flow rate of the medium oil inside the flow channel. The solar collector panel is usually used outdoors, resulting in a large amount of dust collected on the surface of the solar collector panel, resulting in low thermal conversion efficiency of the solar collector panel. Therefore, the inventor proposes a solar collector panel with improved flow channel circulation to solve the above problems. Utility Model Content
