With the rapid development of photovoltaic power generation, the heat dissipation needs of key equipment such as inverters and optimizers are increasing. In order to achieve excellent heat dissipation effect, Huawei innovatively applied thermal conductive potting glue and thermal conductive putty in it's 450W photovoltaic optimizer.
This optimizer adopts an integrated design, with an input voltage range of 8 ~ 80V and a maximum output power of 450W. After the PCBA board is assembled, the surface is directly coated with a layer of thermally conductive potting glue for full potting. The typical thickness is about 2mm. The rich bubble structure enables the thermally conductive potting glue to effectively fill the layout gaps and greatly expand the heat dissipation area. Tests show that after using thermally conductive potting glue, the overall heat dissipation rate of the optimizer can be increased by about 20%.
The heat sink corresponding to the position of the MOS tube is coated with blue thermal paste with excellent thermal conductivity, with a typical thickness of about 0.2mm. Thermal paste can reduce the interface contact thermal resistance between the heat sink and the device and improve the heat transfer efficiency. Test results show that this solution reduces the temperature in the MOS tube area by more than 10°C.
It can be seen that the application of thermal potting glue and thermal mud has significantly improved the heat dissipation effect of the optimizer, expanding the heat dissipation area by more than 20%, and the local temperature drop of the MOS tube exceeds 10°C, effectively ensuring the stable and reliable operation of the product. The two materials each show their unique talents, and together they make the heat dissipation design of Huawei's photovoltaic products reach the industry-leading level.
Thermal conductive materials play a crucial role in ensuring efficient heat dissipation in Huawei photovoltaic optimizers. These optimizers are electronic devices used in solar power systems to maximize the energy output of individual solar panels. As these devices operate, they generate heat that needs to be dissipated effectively to maintain their performance and reliability.
Here's how thermal conductive materials contribute to worry-free heat dissipation in Huawei photovoltaic optimizers:
Heat Transfer: Thermal conductive materials, such as thermal pads or thermal interface materials, have high thermal conductivity. They facilitate the transfer of heat from the heat-generating components, such as power electronics or semiconductors, to heat sinks or other cooling mechanisms.
Interface Enhancement: By filling gaps and irregularities between different components, thermal conductive materials improve the thermal interface between them. This ensures better contact and enhanced heat transfer efficiency, minimizing the risk of thermal resistance and hotspots.
Thermal Management: Huawei photovoltaic optimizers often incorporate advanced thermal management systems. Thermal conductive materials assist in optimizing these systems by efficiently transferring heat away from sensitive components, preventing overheating and potential performance degradation.
Reliability and Longevity: Effective heat dissipation contributes to the overall reliability and longevity of photovoltaic optimizers. By keeping the internal temperature within acceptable limits, thermal conductive materials help prolong the lifespan of electronic components, reducing the likelihood of premature failures.
Design Flexibility: Thermal conductive materials offer design flexibility, allowing for efficient heat dissipation in various form factors and configurations of photovoltaic optimizers. They can be customized to fit specific requirements, ensuring optimal thermal performance in different operating conditions.
Ensuring worry-free heat dissipation through the use of thermal conductive materials in Huawei photovoltaic optimizers is essential for maximizing energy conversion efficiency and maintaining the long-term performance of the solar power system. By effectively managing heat, these materials contribute to the overall reliability and stability of the photovoltaic optimization process.
