Description

Technical Field

[0001] This utility model relates to the field of solar thermal utilization technology, specifically to a heat preservation device for pressure-bearing solar collectors. Background Technology

[0002] Pressure-bearing solar collectors are an important component of solar water heaters. They are mainly used to absorb sunlight and convert it into heat energy to heat water. These collectors are usually made of metal materials with high thermal conductivity and are coated with a selective absorption film to improve the absorption efficiency of light energy.

[0003] However, the main challenge in the application of water is the system's antifreeze problem, especially in northern regions where there are continuous cloudy days and snow in winter. If the system freezes and breaks down, it will increase a lot of additional maintenance costs.

[0004] To address the aforementioned technical issues, as disclosed in CN204421407U, a heat preservation device for pressurized solar collectors achieves anti-freezing and heat preservation effects on the collectors. Especially in winter rainy or snowy weather, the roller shutter prevents the collector components from freezing and cracking due to excessively low temperatures, reducing losses. Simultaneously, the roller shutter provides insulation, preventing the collectors from releasing heat directly, thus achieving a more sustained solar heat preservation effect. Once installed, the entire device has a simple structure, is easy to install, and does not require damage to the original collector structure. After installation, the roller shutter automatically raises and lowers based on sunlight, reducing manual intervention while simultaneously achieving anti-freezing and heat preservation of the solar collectors.

[0005] The aforementioned patent also has the following shortcomings: In actual use, the roller shutter will open and close at different times, making it impossible to keep the heat at all times. At the same time, it cannot improve the required heat preservation effect, so it cannot prevent heat loss when the temperature drops, resulting in poor heat preservation effect. Furthermore, it is not conducive to disassembly and maintenance during actual use. Utility Model Content
