Liquid cooling connectors are critical components for modern high-density liquid cooling systems. As AI servers and data centers pursue higher computing power and lower PUE, traditional air cooling and ordinary pipe connectors can no longer support long-term high-load operation. As a professional fluid connection solution provider, Hoonsun offers standardized, zero-leakage, low-resistance liquid cooling connectors that greatly improve the stability and maintainability of data center and industrial liquid cooling systems.
A liquid cooling quick connector is a plug-and-play sealed fitting used to connect server cold plates, cooling hoses and rack manifolds. It forms a closed coolant circulation loop and allows fast disassembly and maintenance without draining liquid or introducing air bubbles. For liquid cooling projects, high-quality dry-break connectors are the key to reducing leakage risks and O&M costs.
All Hoonsun liquid cooling connectors adopt a mature dry-break dual-valve self-closing design:
Connected: Internal valve cores open to form a smooth low-resistance flow channel for stable coolant circulation.
Disconnected: Spring-driven dual valves close instantly, achieving near-zero leakage and preventing air and dust from entering the pipeline.
Hoonsun’s product line fully complies with OCP and Open Rack V3 standards, covering standard quick-disconnect, blind-mate and high-flow models for different liquid cooling deployment needs.

UQD & UQDB Standard Connector
Hoonsun UQD and UQDB are mainstream dry-break liquid cooling connectors for server-level cooling. Made of polished 316L stainless steel with composite sealing rings, they support tool-free quick maintenance. The UQDB blind-mate design solves alignment errors in dense cabinets, ideal for large-scale automated deployment.
BMQC & LQC High-Flow Connector
Hoonsun BMQC and LQC are industrial-grade enhanced models. Optimized large-diameter flow channels reduce pressure loss significantly. With excellent vibration resistance and misalignment tolerance, they are suitable for long-term continuous operation of rack manifolds and high-power main cooling loops.
• Zero-Leakage Reliability: Precision dual-valve structure and high-grade sealing materials ensure zero leakage during connection and disconnection, avoiding equipment failure and downtime.
• Low Flow Resistance & Energy Saving: Optimized internal channels reduce pump load and system pressure loss, effectively lowering data center PUE.
• Strong Compatibility & Durability: Adaptable to deionized water and glycol coolant, working from -40°C to +105°C. Supports thousands of plug cycles with stable performance.
• Low O&M Cost: Standardized interchangeable design, high stability and long service life greatly reduce later maintenance frequency.
Hoonsun liquid cooling connectors are widely adopted in high-power thermal management industries:
• AI & Cloud Data Centers: GPU server cold plate and manifold connection for high-density computing heat dissipation.
• New Energy Storage: Closed cooling loop for battery clusters to ensure temperature stability and safety.
• Industrial High-Power Equipment: Laser devices, CNC and automation equipment liquid cooling connection.
• High-Power Charging Infrastructure: Liquid cooling heat dissipation for ultra-fast charging piles under high-load conditions.
Liquid cooling connectors determine the safety and efficiency of the entire thermal management system. As a reliable manufacturer, Hoonsun provides standardized zero-leakage, low-resistance liquid cooling connector series, covering from single-node servers to large-scale cluster and energy storage cooling systems. For modern green, low-PUE and high-reliability liquid cooling projects, Hoonsun delivers cost-effective and stable fluid connection solutions.
