Product Parameters

Notes

1. Rated Efficiency: Based on total solar irradiance of 1000 W/m² on the absorber surface, with an average temperature difference of 50°C between the collector and ambient air.

2. Rated Output: Refers to thermal output at irradiance levels of 400, 700, and 1000 W/m², under a temperature difference of 50°C, calculated as:
Rated efficiency × Absorber area × Solar irradiance.

Q1: What is a heat pipe solar collector?
A1: A heat pipe solar collector uses evacuated glass tubes with sealed copper pipes to efficiently transfer solar heat to a circulating fluid. It's known for its fast start-up, high efficiency, and excellent performance in cold climates.

Q2: How does a heat pipe work in solar collectors?
A2: The heat pipe inside the evacuated tube contains a small amount of fluid. When heated by sunlight, the fluid vaporizes and rises to the condenser end, transferring heat to the water system. The vapor then condenses and returns to the bottom, repeating the cycle.

Q3: What are the advantages of heat pipe collectors over flat plate collectors?
A3: Heat pipe collectors offer better performance in low sunlight or cold environments, faster response time, and less heat loss due to vacuum insulation. They're ideal for areas with cold winters or industrial hot water needs.

Q4: Can heat pipe collectors be used year-round?
A4: Yes. Their design with vacuum insulation and antifreeze compatibility makes them suitable for year-round operation, even in sub-zero temperatures.

Q5: What maintenance is required for heat pipe solar collectors?
A5: Maintenance is minimal. Regularly checking for leaks, cleaning the glass tubes, and inspecting the heat exchanger once a year is typically sufficient.
