Application of Thermally Conductive Gel in Heat Dissipation of Photovoltaic Inverters

Application of thermally conductive gel in heat dissipation of photovoltaic inverters

A photovoltaic inverter is a device that converts direct current generated by solar panels into alternating current. After being converted by the photovoltaic inverter, the DC power generated by the solar panels can be directly supplied to households, businesses or the public grid. Photovoltaic inverters play a vital role in solar power generation systems, and their efficiency and reliability directly affect the power generation and life of solar power generation systems. As the global photovoltaic trend accelerates, it will drive the need for higher performance and more cost-effective thermal management solutions.

Thermally conductive materials are very important in the cooling application of photovoltaic inverters. A photovoltaic inverter is a device that converts direct current generated by solar panels into alternating current. During this process, a large amount of heat will be generated. If the heat cannot be dissipated in time, the efficiency and life of the inverter will be affected. Therefore, the use of high thermal conductivity materials in photovoltaic inverters can effectively improve heat dissipation efficiency and ensure the normal operation of the inverter.

Reducing the temperature in time can effectively ensure the normal use of the photovoltaic inverter. In addition to optimizing the structure of the heat source and reducing its calorific value, installing heat dissipation devices for heat dissipation is also the main heat dissipation method at present. Air is a bad conductor of heat. There is a gap in the contact interface between the device and the heat source in the photovoltaic inverter, and the heat will be resisted by the air when it is conducted between the two, so the heat dissipation effect will be greatly reduced.

Thermally conductive gel is a high-performance thermally conductive material coated between the heating device and the heat sink device in the photovoltaic equipment. It can effectively reduce the contact thermal resistance between the two, can fill the pits in the gap, and remove the air in the gap, so that the heat can be released. It is quickly conducted into the cooling device through the thermal conductive gel to ensure that the heating device can be used normally.

AOK thermally conductive gel feature long-lasting UV stability, high thermal conductivity formulations, extremely high bond strength to reduce failures due to moisture, and are also electrically insulating. Addresses the growing need for improved thermal management in electronic product designs across virtually all industries. Thermally conductive gels offer a wide range of adaptable products for encapsulation and potting applications. The low viscosity of these products prior to curing allows them to be easily processed and fully embedded in high content, delicate wire and solder joints.

The main characteristics of thermal conductive gel are as follows:

1. Good thermal conductivity: made of high thermal conductivity material, it can effectively conduct heat and improve the heat dissipation effect.

2. Good adhesion: it can firmly adhere to the surface of equipment such as radiators or temperature sensors, and is not easy to fall off.

3. Good flexibility: it has a certain degree of flexibility, which can adapt to different shapes of equipment surfaces and improve the heat dissipation effect.

4. High temperature resistance: it has certain high temperature resistance and can maintain stable thermal conductivity at higher temperatures.

5. Environmental protection and safety: it does not contain harmful substances, and is harmless to the environment and human body.

The great development of photovoltaic power generation, wind power generation and energy storage industries has created a large number of thermal management functional solutions (thermal modules, thermal interface materials, etc.), which can be applied to photovoltaic power generation, wind power generation and energy storage, electric vehicles, energy storage systems, motors, and other power electronics. At present, the company has carried out in-depth cooperation with leading enterprises in the industry in various fields such as photovoltaics, wind power, and energy storage.
