As computing power and electricity reach every corner of the world, and as megawatt ultra-fast charging and deep-sea wind power  become the norm, heat dissipation is no longer an "auxiliary link" but a core battlefield that determines the performance ceiling of the  system. At the industrial inflection point where liquid cooling technology fully replaces air cooling, a seemingly small circulating pump  is actually the "heart" of the entire thermal management system. As a technology-driven enterprise with more than 20 years of experience in the field of precision Micro magnetic gear pumps, JONSN Fluid Technology deeply understands that the liquid cooling upgrade in the new energy industry requires not compromises with general-purpose pumps, but precise solutions tailored to extreme working conditions.

From the cable cooling of megawatt-class super charging piles to the salt spray isolation of offshore wind power converters; from the  silent liquid cooling CDU of 5G base stations to the strict red line of PUE below 1.25 for data centers; from the precise temperature difference control of energy storage cells to the long-term stable operation at the ten-thousand-meter deep sea — the JONSN MRV/MRF/MRC  series Micro magnetic gear pumps are redefining the power boundaries of liquid cooling systems with their technical genes of  "zero leakage, no pulsation, high pressure difference, and long service life". 

I. Super Charging Piles: Breaking the Heat Dissipation Deadlock of "Megawatt Ultra-Fast Charging"

Industry Pain Points: In 2024, the scale of China's liquid-cooled super charging market reached 57.8billion yuan, a year-on-year increase  of 49%. As BYD's megawatt ultra-fast charging and Zeekr's 1.2MW liquid-cooled piles achieve "5minutes of charging for 500 kilometers  of range", the risk of thermal runaway of charging cables and high-power modules rises exponentially. The heat dissipation efficiency of  traditional air cooling is only about0.51kW/℃·m², while the full liquid cooling system can reach 510kW/℃·m², a thousand-fold improvement in heat dissipation capacity. However, the problem lies in: the silicone oil circulation system for long charging cables (>5meters) requires a core power source with small flow, high head and high pressure resistance, and must be reliably zero-leakage.

Application Case 

In a 1.2MW full liquid-cooled super charging pile project of a leading charging pile enterprise, JONSN MRF series gear pumps were adopted as the main circulation pumps. Under a system pressure of 14bar, a stable flow rate of 45L/min was achieved. After 12 months of continuous operation, the pump body temperature rise was <15℃ and the flow attenuation was <2%. Compared with the previous imported  centrifugal pump solution, JONSN performed better in low-temperature start-up and pressure stability, with a cost optimization of more  than 30%.

II. Offshore Wind Power: The "Maintenance-Free" Promise Conquering Salt Spray and Vibration 

Industry Pain Points: Offshore wind turbines are far from the coast, with short maintenance windows and extremely high maintenance  costs. Converters and transformers generate extremely high heat flux density when operating at full load, and are exposed to high salt  spray and high humidity environments for a long time. Traditional air cooling systems are prone to inhale corrosive air, while the  mechanical seals of ordinary water pumps have an average service life of less than 2years under the erosion of vibration and salt  spray. The liquid cooling system for offshore wind power requires the pump unit to have an MTBF (Mean Time Between Failures) of  >50,000 hours and reliable sealing performance.

Application Case 

In a converter liquid cooling renovation project for a 300MW offshore wind farm in the East China Sea, the original centrifugal pumps suffered coolant contamination due to mechanical seal leakage, with 3 failures per year and a single offshore maintenance cost exceeding  150,000 yuan. After replacement with JONSN MRC series (0.8‒14L/min) magnetic gear pumps, their self-priming capability with inlet  vacuum of -�.���MPa optimized pipeline design, achieving ��,��� hours of continuous trouble-free operation and effectively eliminating  leakage risks. 

Ⅲ. �G Base Stations: Keeping Computing Power Cool and Silent 

Industry Pain Points Power consumption of �G base stations is �‒� times that of �G, leading to a surge in heat flux density of AAU and BBU modules. Traditional air conditioning cooling accounts for ��%‒��% of computer room energy consumption, and fan noise in outdoor base stations  easily triggers resident complaints. Cold plate liquid cooling is the preferred solution, but CDU (Cooling Distribution Unit) inside base  stations has extremely limited space and requires noise <��dB, posing strict challenges to pump volume, quietness and gas-liquid  two-phase adaptability.
