JPE Product Spotlight | Application of JPE UQD Quick Disconnects in Liquid Cooling Systems

JPE has long been dedicated to the research, development, and manufacturing of instrumentation valves and fittings. With extensive industry applications and experience serving multinational corporations, the JPE team is equipped to offer precise recommendations for product performance and system configuration.



In recent years, our products have played a crucial role in semiconductor, electronics R&D, high-performance computing (HPC), and data center cooling systems. These environments demand products that meet high safety and stability standards to support intensive computational tasks performed by intelligent servers. In such settings, especially in liquid cooling and power management systems, JPE's solutions are critical to ensuring system stability, improving energy efficiency, and extending the lifespan of server equipment.

With the explosive growth of AI technologies—particularly generative AI, cloud computing, and deep learning—the demand for server and data center computing power continues to rise. Today’s advanced AI chips can reach power consumption levels of 1000W, far exceeding the approximate 750W thermal limit of traditional air-cooling systems. This indicates that air cooling can no longer support the high-performance computing requirements of AI systems.



In response, liquid cooling technology has rapidly emerged as the mainstream thermal management solution for global data centers and AI servers. Liquid cooling not only offers superior heat exchange efficiency but also helps reduce energy loss and equipment wear. However, the challenges of liquid cooling have evolved beyond heat dissipation to include environmental controls involving high humidity, corrosion, and precision.



■ UQD Universal Quick Disconnect
JPE's UQD quick disconnects are designed specifically for liquid cooling systems in HPC and data center environments. The UQD standard, initiated by Intel, is part of the Open Compute Project (OCP) as a publicly available specification. JPE’s UQD series fully complies with OCP standards, and is built upon years of expertise in designing and manufacturing quick disconnects. These products not only meet but exceed baseline performance benchmarks, offering enhanced cooling efficiency and system reliability.

To ensure the optimal and safest conditions for water-cooled systems, Appendix G.15 of the IEC 62368-1 standard requires the following tests:

1. Hydrostatic pressure test
2. Compatibility test of tubing and fittings
3. Vibration test
4. Thermal cycling test
5. Stress test

■ Product Features
1. Fully compliant with OCP design standards and user-friendly operation
2. Successfully tested per IEC 62368-1 Appendix G.15
3. Dual-valve quick disconnects, with independent sealing upon disconnection
4. Fluid leakage during disconnection is significantly below OCP thresholds
5. Flat interface design minimizes fluid drips and prevents air ingress during connection/disconnection
6. Valve body made of SS316L stainless steel, highly compatible with various fluids
7. Dual-layer EPDM seals ensure effective sealing and reduced leakage risk (Other materials available upon request—please contact our sales team)
