As computing power and electricity go global, and megawatt ultra-fast charging and offshore wind power become the norm, heat dissipation is no longer an auxiliary link but the 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 company with over 20 years of expertise in precision mini gear pumps, JONSN Fluid Technology knows well that the liquid cooling upgrade of the new energy industry requires tailored solutions for extreme working conditions, not compromises with general-purpose pumps.

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

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

Industry Pain Points

China’s liquid cooling super charging market reached 57.8 billion yuan in 2024, a year-on-year increase of 49%. As BYD megawatt ultra-fast charging and Zeekr 1.2MW liquid cooling piles achieve “5 minutes of charging for 500 kilometers of range”, the thermal runaway risk of charging cables and high-power modules rises exponentially. The heat dissipation efficiency of traditional air cooling is only about 0.51kW/℃·m², while full liquid cooling systems can reach 510kW/℃·m², a thousand-fold improvement. However, silicone oil circulation systems for long cables (>5 meters) require a core power source with small flow, high head, and high pressure resistance, and must achieve reliable zero leakage.

Application Case

In a 1.2MW full liquid cooling super charging pile project for a leading manufacturer, JONSN MRF series gear pumps were used as main circulation pumps, delivering stable 45L/min flow at 14bar system pressure. After 12 months of continuous operation, pump temperature rise was <15℃ and flow attenuation <2%. Compared with the previous imported centrifugal pump solution, JONSN showed better low-temperature startup and pressure stability, with cost optimization of over 30%.

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

Industry Pain Points

Offshore wind turbines are far from shore, with short maintenance windows and extremely high costs. Converters and transformers generate extremely high heat flux density at full load and are exposed to high salt spray and humidity for a long time. Traditional air cooling systems easily inhale corrosive air, while mechanical seals of ordinary water pumps last less than 2 years under vibration and salt spray erosion. Liquid cooling systems for offshore wind power require pumps with >50,000 hours MTBF (Mean Time Between Failures) and reliable sealing.

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 -0.095MPa optimized pipeline design, achieving 18,000 hours of continuous trouble-free operation and effectively eliminating leakage risks.

3. 5G Base Stations: Keeping Computing Power Cool and Silent

Industry Pain Points

Power consumption of 5G base stations is 3–4 times that of 4G, leading to a surge in heat flux density of AAU and BBU modules. Traditional air conditioning cooling accounts for 15%–50% 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 <60dB, posing strict challenges to pump volume, quietness and gas-liquid two-phase adaptability.

Application Case

In a liquid cooling renovation of 5G macro base stations for a South China communication operator, the CDU had only a 120mm×80mm installation space. JONSN customized MRV series mini pumps drove deionized water + corrosion inhibitor medium at 2L/min flow and 8bar pressure difference, controlling BBU module temperature difference within ±1℃. Compared with the original centrifugal pump solution, energy consumption was reduced by 40%, and high-frequency whistling was effectively eliminated.

4. Data Centers: The Art of Precise Flow Under the PUE 1.25 Red Line

Industry Pain Points

Policies clearly require that new data centers from 2025 have PUE below 1.3, and East Data West Computing nodes below 1.25. Air cooling + water cooling backplane solutions have reached physical limits, making liquid cooling the only way out. However, data center liquid cooling has extremely strict pump requirements: real-time flow adjustment according to CPU/GPU load (PID or AI algorithm control), and must ensure no pulsation and high precision to avoid local hot spots on chips.

Application Case

An AI computing center adopted a combination of JONSN MRA series (100ml–2000ml/min) and MRB series (400ml–4800ml/min) for GPU node microchannel cold plates and rack-level CDU circulation. In full-load testing, chip surface temperature difference was controlled <2℃ (industry average 5–8℃), and system PUE dropped from 1.45 to 1.18. More importantly, in an extreme test of dry running for 2 hours after simulated power failure, JONSN pumps showed no attenuation in flow linearity after restart, demonstrating better reliability redundancy than centrifugal pumps.

5. Energy Storage Equipment: Temperature Control Revolution from Thermal Runaway to 8000 Cycles

Industry Pain Points

Thermal runaway is a major risk in electrochemical energy storage power stations. Liquid cooling systems extend battery cycle life to over 8000 cycles and reduce TCO (Total Cost of Ownership) by 25% by maintaining cell temperature difference <3℃. However, energy storage cabinets have crowded internal space, and coolant tends to produce impurities after long-term operation, causing clogging and wear in ordinary pumps, leading to flow attenuation and inaccurate temperature control.

Application Case

In a 200MWh containerized energy storage project, JONSN MRV series pumps served as the core of liquid cooling pipeline circulation, achieving a maximum single-cluster cell temperature difference of 2.1℃ (design target <3℃) under ethylene glycol aqueous solution medium and 10bar system pressure. Verified by 1200 charge-discharge cycles, pump flow attenuation <1.5%, temperature control consistency increased by 40% compared with the original solution, directly supporting the customer’s 8000-cycle life warranty commitment.
