Definition of Solar Photovoltaic Radiator
Definition of Solar Photovoltaic Radiator
In order to improve the utilization efficiency of solar energy, solar cell modules are combined with solar collectors to make Solar Photovoltaic radiators that integrate the functions of solar cells and solar collectors. Under normal lighting conditions and ambient temperature, the flat-plate Solar Photovoltaic radiator system panels with water as the working fluid can effectively reduce the temperature of solar cells, improve the photoelectric conversion efficiency of solar cells, and thus obtain higher output power.
Necessity of Solar Photovoltaic Radiator
The power generation efficiency of photovoltaic panels will decrease in high temperature environments (>25°C). For every 1°C increase in temperature, the output power of silicon-based photovoltaic panels may decrease by 0.4%~0.5%. Therefore, effective heat dissipation management of the photovoltaic heat sinks can significantly increase power generation and extend component life.
Key materials and optimized design of solar photovoltaic radiator
| Materials/Technology | Features |
| Aluminum alloy (6063) | Lightweight, high thermal conductivity (~200W/m·K), low cost |
| Copper microchannel | Excellent thermal conductivity (385W/m·K), suitable for high-power CPV |
| Thermal conductive structural adhesive | High bonding strength (8MPa), thermal conductivity 1.2W/m·K, used for bonding photovoltaic panels and heat sinks |
| Dent/trapezoidal heat sink | Experiments show that it can reduce PV temperature by 44.4°C and increase efficiency by 16.89% |
The selection of solar photovoltaic radiators needs to be combined with factors such as ambient temperature, system power, cost budget, etc. The future trend will be towards intelligence, composite heat dissipation, and new material applications to further improve the overall efficiency of photovoltaic systems.
About Die cast radiators
High-quality Die cast radiators use aviation aluminum as an ideal medium for heat energy conversion. The European standard EN46100 has a price of more than 14,000 yuan per ton, which is relatively more expensive than some other materials.
Regarding thermal conductivity, the thermal conductivity of Die cast radiator is 237w/m.k, with high pressure resistance and high metal thermal strength. According to the test of the National Testing Center, its metal thermal strength is 2.27W/Kg℃. Die cast radiator has high heat, fast heat dissipation and high efficiency. Die cast radiator has a unique chimney-like structure for heat dissipation, which can make the room warm and comfortable in 15 minutes. This is also an important factor for more users to choose it as the heating terminal.
