Water Cooling Head Water Cooling Plate 40*280mm

The Water Cooling Head Water Cooling Plate 40*280mm is a precision liquid cooling component designed for high-performance thermal management in industrial electronics, server systems, and advanced computing applications. Professional engineers and system integrators use this cooling plate to dissipate concentrated heat loads from CPUs, GPUs, and power electronics with superior efficiency compared to air cooling solutions. This product solves the critical problem of thermal throttling and component degradation in demanding environments by maintaining optimal operating temperatures through direct liquid contact cooling.

Product Overview

The Water Cooling Head Water Cooling Plate operates on the principle of forced convection heat transfer, where coolant circulates through internal microchannels machined into the aluminum or copper base plate. The 40*280mm form factor provides an extended cooling surface area optimized for linear heat sources such as power rails, LED arrays, and semiconductor packages. The plate features precision-engineered inlet and outlet ports designed for standard water cooling loop integration, with internal turbulence-inducing features that maximize heat transfer coefficient while maintaining acceptable pressure drop across the cooling circuit.

This cooling plate model stands out through its optimized channel geometry that delivers superior thermal conductivity and uniform temperature distribution across the entire 280mm length. The compact 40mm width allows for space-efficient installation in constrained environments while maintaining high volumetric heat dissipation capacity. Compatible with both open-loop and closed-loop water cooling systems, this plate accommodates flow rates between 2-6 liters per minute, making it versatile for various industrial cooling applications from laboratory test benches to production-grade thermal management systems.

How to Use

Begin installation by preparing your water cooling loop with distilled water or approved coolant, ensuring the system is properly filled and bled of air before connecting the cooling plate. Mount the Water Cooling Head Water Cooling Plate 40*280mm directly onto your heat source using thermal interface material such as thermal paste or thermal pads applied in a thin, uniform layer to ensure optimal contact. Connect the inlet port to your pump output and the outlet port to your reservoir or radiator using standard G1/4 quick-disconnect fittings or barbed connectors, ensuring all connections are tight to prevent leakage.

Once installed, verify proper coolant flow by observing the outlet temperature rise relative to inlet temperature, typically 5-10 degrees Celsius under normal operating conditions. Monitor system pressure to ensure it remains below 3 bar to prevent seal degradation and maintain long-term reliability. For optimal performance, maintain coolant temperature between 20-40 degrees Celsius by adjusting radiator fan speed or pump flow rate. Periodically inspect inlet and outlet ports for any signs of coolant leakage or discoloration, and replace coolant every 12-24 months or if contamination is detected.

Frequently Asked Questions

What is the thermal resistance of the 40*280mm cooling plate at different flow rates?

The Water Cooling Head Water Cooling Plate achieves thermal resistance of approximately 0.15 K/W at the recommended flow rate of 4-5 liters per minute. At lower flow rates of 2-3 liters per minute, thermal resistance increases to around 0.20-0.25 K/W due to reduced convection coefficient. At maximum flow rates of 6 liters per minute, thermal resistance can be reduced to approximately 0.12 K/W, though pressure drop also increases proportionally. These values assume proper thermal interface material application and direct contact with a flat heat source.

Can this cooling plate be used with glycol-based coolants or only water?

The Water Cooling Head Water Cooling Plate is compatible with distilled water, deionized water, and approved water-ethylene glycol mixtures commonly used in industrial cooling systems. Glycol-based coolants reduce thermal conductivity by approximately 10-15 percent compared to pure water, resulting in slightly higher thermal resistance. Ensure any coolant used is compatible with aluminum or copper materials to prevent corrosion. Avoid using propylene glycol or silicone-based fluids unless specifically verified with the manufacturer, as these may degrade internal seals or cause microbial growth in extended systems.

What mounting hardware and thermal interface materials are recommended for installation?

Mount the cooling plate using stainless steel or zinc-plated fasteners to prevent galvanic corrosion at the aluminum or copper interface. Apply thermal interface material such as thermal paste with 3-5 W/mK conductivity, or thermal pads rated for 1-3 W/mK in a thin uniform layer of 0.1-0.2mm thickness. Avoid excessive clamping force that may damage the plate or create uneven pressure distribution. For optimal thermal contact, ensure the mounting surface is clean, flat, and free of oxidation. Consider using thermal interface material with phase-change properties for improved long-term performance and reduced pump-out effect over extended operating periods.
