Water Cooling Head Water Cooling Plate 40*320mm

The Water Cooling Head Water Cooling Plate 40*320mm is a precision liquid cooling component designed for high-performance thermal management in industrial electronics, laser systems, and semiconductor cooling applications. Professional engineers and technicians use this cooling plate to dissipate concentrated heat loads in compact spaces where traditional air cooling proves inadequate. This product solves critical thermal management challenges by providing efficient heat transfer through direct liquid contact, maintaining optimal operating temperatures for sensitive electronic components and extending equipment lifespan.

Product Overview

The 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 material. The 40*320mm dimensions provide an optimal surface area for moderate to high heat flux applications, typically handling 500-2000W of thermal energy depending on coolant flow rate and temperature differential. The flat mounting surface ensures excellent thermal contact with heat sources, while the internal channel design minimizes pressure drop and turbulence, enabling efficient heat removal even at lower flow rates between 2-6 liters per minute.

This cooling plate model stands out due to its compact rectangular geometry that fits seamlessly into space-constrained systems such as laser diode arrays, RF amplifiers, and industrial control cabinets. The precision-engineered inlet and outlet ports accommodate standard barbed or threaded fittings, allowing easy integration with existing chiller systems. Advanced manufacturing techniques ensure uniform channel depth and minimal manufacturing tolerances, preventing hot spots and ensuring consistent thermal performance across the entire cooling surface.

Key Specifications

Key Features

• Optimized 40*320mm form factor provides maximum heat dissipation in linear, space-constrained applications with minimal footprint impact
• Precision-machined internal microchannels ensure uniform coolant distribution and turbulent flow for enhanced heat transfer coefficients exceeding 10,000 W/m²K
• Flat mounting surface with high flatness tolerance maintains consistent thermal contact resistance below 0.01 K/W when properly mounted

Applications and Use Cases

• Laser Diode Array Cooling: Maintains precise junction temperatures for high-power laser modules in industrial cutting and marking systems, preventing wavelength drift and power degradation
• RF Amplifier Thermal Management: Dissipates heat from power transistors in telecommunications and radar equipment, ensuring stable gain and linearity across operating frequency ranges
• Semiconductor Test Equipment: Cools DUT (Device Under Test) holders and thermal chambers in semiconductor characterization systems requiring precise temperature control within ±0.5°C
• Industrial Control Cabinet Cooling: Manages heat from power supplies, inverters, and control modules in manufacturing equipment, extending component lifespan and reducing downtime
• Medical Device Thermal Regulation: Maintains optimal operating temperatures in ultrasound transducer arrays and surgical laser systems requiring stable thermal conditions

How to Use

Installation begins with mounting the cooling plate directly onto the heat source using thermal interface material such as thermal grease or phase-change pads to fill microscopic surface irregularities and minimize thermal contact resistance. Secure the plate using mounting brackets or clamps that apply uniform pressure across the entire surface, typically 0.5-1.5 MPa clamping force. Connect the inlet port to your chiller system's outlet using appropriate tubing (typically 10-12mm inner diameter), and connect the outlet port back to the chiller inlet, ensuring the system is filled with degassed coolant before operation to prevent air pockets that reduce thermal performance.

Establish coolant flow at 2-4 liters per minute for most applications, monitoring inlet and outlet temperatures to calculate actual heat dissipation using the formula Q = m × Cp × ΔT, where m is mass flow rate and ΔT is temperature differential. Maintain inlet coolant temperature between 15-35°C for optimal performance, and inspect connection points weekly for leaks during the first month of operation. Replace thermal interface material annually or whenever the cooling plate is removed, as material degradation significantly increases thermal resistance over time.
