[0002] With the continuous growth of global energy demand and the increasing severity of environmental problems, solar energy, as a clean and renewable energy source, has received widespread attention. Solar collectors are key equipment in solar thermal utilization systems and are widely used in hot water supply, heating, industrial production and other fields.

[0003] However, traditional flat-plate solar collectors have some limitations in terms of structural strength and performance, which restricts their use in complex environments and demanding applications. Traditional flat-plate solar collectors usually use thin metal plates or plastic materials, which have low structural strength and are easily deformed or damaged under external forces such as wind pressure and snow pressure, affecting their service life. Therefore, a reinforced flat-plate solar collector is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Specifically, mounting holes are provided at the four corners of the upper surface of the mounting plate 4, and three connecting plates 3 are distributed at equal intervals on the upper surface of the mounting plate 4.

[0020] Please see Figures 2 to 4 In this embodiment, the collector assembly 2 includes a reinforcing frame 201 fixed to the inclined plate 1 by bolts. An insulation layer 202 is fixed inside the reinforcing frame 201. A first heat-conducting plate 203 is fixed on the insulation layer 202. A second heat-conducting plate 204 is welded and fixed to the upper surface of the first heat-conducting plate 203. Placement grooves are opened on opposite sides of the first heat-conducting plate 203 and the second heat-conducting plate 204. A matching heat-conducting circulation pipe 205 is welded and fixed inside the placement groove. A heat-absorbing layer 206 is fixed to the upper surface of the second heat-conducting plate 204. The liquid inlet and liquid outlet of the heat-conducting circulation pipe 205 penetrate the insulation layer 202 and the reinforcing frame 201 and extend to the back of the reinforcing frame 201.

[0021] Specifically, the heat-absorbing layer 206 has a high absorptivity and low emissivity, enabling it to efficiently absorb solar radiation energy and convert it into heat energy. The heat energy absorbed by the heat-absorbing layer 206 is transferred to the heat-conducting circulation pipe 205 through the second heat-conducting plate 204 and the first heat-conducting plate 203. The fluid in the heat-conducting circulation pipe 205, such as water or antifreeze, is heated. The heated fluid is then transported to an external heat storage device or point of use, such as a hot water tank or heating system, through the inlet and outlet ends of the heat-conducting circulation pipe 205. The insulation layer 202 is made of glass fiber material, which effectively reduces heat loss and ensures efficient heat transfer inside the collector. It is a flat-plate solar collector.

In some special application environments, such as high altitude and cold regions, it can resist the effects of external forces such as wind pressure and snow pressure to ensure long-term stable operation.

[0023] It should be noted that the reinforced frame 201 provides structural support and ensures the stability of the collector assembly 2. Both the connecting plate 3 and the mounting plate 4 are made of stainless steel. The connecting plate 3 fixes the inclined plate 1 to the mounting plate 4, ensuring the stable installation and structural integrity of the entire collector.

[0024] The working principle of the above embodiments is as follows: In use, the heat-absorbing layer 206, with its high absorptivity and low emissivity, can efficiently absorb solar radiation energy and convert it into heat energy. The heat energy absorbed by the heat-absorbing layer 206 is transferred to the heat-conducting circulation pipe 205 through the second heat-conducting plate 204 and the first heat-conducting plate 203. The fluid in the heat-conducting circulation pipe 205, such as water or antifreeze, is heated. The heated fluid is transported to the external heat storage device or point of use, such as a hot water tank or heating system, through the inlet and outlet of the heat-conducting circulation pipe 205. The insulation layer 202 is made of glass fiber material, which effectively reduces heat loss and ensures efficient heat transfer inside the collector. The reinforced frame 201 provides structural support and ensures the stability of the collector assembly 2. The connecting plate 3 and the mounting plate 4 are both made of stainless steel. The connecting plate 3 fixes the inclined plate 1 to the mounting plate 4, ensuring the stable installation of the entire collector.
