On the vast battlefield of oilfield extraction, "nodding donkeys" (beam pumping units) work tirelessly day and night, contributing to the nation's energy industry. However, behind this seemingly stable production lies a critical issue affecting equipment reliability—heat dissipation in frequency converters. Nanjing Oulu Electric's independently developed and manufactured frequency converters, with their exceptional heat dissipation upgrade technology, have become reliable "guardians" of oil wells.

In the past, due to ineffective heat dissipation solutions, frequency converters were prone to overheating failures during prolonged operation of beam pumping units. This not only impacted production efficiency but also increased equipment maintenance costs, posing significant challenges for oilfield enterprises. To tackle this problem, Nanjing Oulu Electric's R&D team conducted in-depth research, continuous testing, and improvements, ultimately developing an efficient heat dissipation system.

The newly upgraded Oulu frequency converters demonstrate outstanding features and advantages in heat dissipation. They adopt an air-cooling control method, which effectively dissipates heat generated during operation, ensuring internal components remain within an optimal temperature range. Additionally, they are equipped with module temperature detection functionality, enabling real-time monitoring of module temperature. The fans in the new converters are designed to be detachable and easy to replace. After removing the fans, the bottom heat sinks are exposed, making dust cleaning convenient and safe. Moreover, when the module temperature reaches 105°C, the frequency converter promptly issues an alarm signal. This alarm mechanism is crucial as it alerts operators to potential overheating risks in time, preventing equipment damage, performance degradation, and other issues caused by excessive heat. This ensures stable and reliable operation of the frequency converters in applications such as oilfield pumping, reducing downtime  caused by abnormal temperatures and improving overall efficiency.

In practical applications, Nanjing Oulu Electric's frequency converters have delivered exceptional performance. In oil well equipment projects across large oilfields in Shandong, Henan, Shaanxi, and Xinjiang, the installation of these upgraded heat dissipation systems has significantly enhanced the operational stability of beam pumping units. Incidents of failure shutdowns caused by overheating have been significantly reduced, while the effective operational time of the equipment has substantially increased.

Furthermore, the stable operation of beam pumping units has reduced the workload for maintenance personnel, decreasing the demand for human and material resources in repairs. Additionally, the extended lifespan of the frequency converters has lowered the costs associated with equipment replacement and upgrades.

       Nanjing Oulu Electric's upgraded heat dissipation technology for frequency converters brings new hope to the oilfield industry. With outstanding performance and reliable quality, it safeguards the stable operation of every oil well, supporting oilfield enterprises in achieving efficient, energy-saving, and sustainable development. Choosing Nanjing Oulu Electric’s frequency converters means choosing stability and efficiency. Let us work together to create a brighter future for oilfield extraction!
