Product advantage of Aluminum Profile Water coold plate for equipment heat sink

Just like heat sink is a word that people will know this is the cooling device which plays an important role in modern equipment and machines, without a cooling heat sink, it could destroy the operation system and thus would cost thousands of dollars for the loss, however, some of the heat sinks, no matter the active heat sink or passive heat sink, its cooling power ability are all has the limitation about 200-300W, very seldom heat sinks can have a strong power in cooling more than 300W, so is that the limitation for the modern radiator?

The answer is no, the technology is changing from time to time, and more and more advanced technique is appearing and which are all contributed with human intelligence and devotion, so as the equipment is becoming more advanced and its operation devices are demanding for higher cooling heat sink, so now the water cooling plate has birthed to meet the requirement of large equipment, for example, the laser equipment needs high power in electricity, and it must will generate more heating, so if you want keep the temperature be normal and operation be steady, you will need the high cooling power of laser equipment cold plate, this water cooling plate is designated for the laser equipment, it could cool down more than 500W or 1000W,and even more than 3000W is available, this cooling way is using liquid flowing and can adjust cooling power according to the Flow speed and water volume. The water copper tube for transmitting the water, and heat source attached with water cold plate to touch the heat and spread out the heat until lower temperature.

Aluminum Profile Water Cooling Plate

1. Basic Introduction

• Material: AL6063 / AL6061 (extrusion aluminum, good thermal conductivity & machinability)
• Structure: Inside with water channel / flow passage, external with mounting surface
• Cooling medium: Water, glycol water, cooling oil

2. Main Manufacturing Types

(1) Extruded Aluminum Profile + Cover Plate

• Process: Extrude one side with groove channel → weld/bond cover plate → drill inlet/outlet
• Features: Low cost, mass production, suitable for flat, long strip water cooling plates

(2) Deep Machining + Friction Stir Welding (FSW)

• Process: CNC mill deep channel → friction stir welding cover plate
• Features: High strength, no leakage, high pressure resistance, widely used in industry, new energy

(3) Skived + Bonded / Welded

• For high-power density, complex flow field

3. Typical Structure & Shape

• Rectangular flat plate (most common for IGBT, inverter, battery, laser)
• Long strip type (for equipment cabinet, power module array)
• Multi-cavity, serpentine, parallel, Z-type, S-type water channel
• Can be with mounting holes, threaded holes, steps, avoiding holes

4. Advantages

• High heat dissipation efficiency: direct contact liquid cooling, far better than air cooling
• Light weight: aluminum density low, suitable for equipment integration
• Good plasticity: extruded profile can be made into complex section
• High processing flexibility: CNC can realize various shapes and interfaces
• Good corrosion resistance with surface treatment

5. Typical Applications

• Industrial power supply / inverter / IGBT / MOSFET
• Laser equipment, laser head water cooling
• New energy vehicle motor controller
• Communication base station, server liquid cooling
• Medical equipment, high-power LED, energy storage equipment

6. Key Design Parameters

• Cooling power & heat flux
• Inlet water temperature & flow rate
• Pressure resistance (1–10 bar commonly)
• Channel width, depth, flow path length
• Surface flatness & roughness (for heat contact)
• Interface: G1/4, M5/M6 thread, quick connector

7. Surface Treatment

• Anodizing (common, anti-corrosion, insulation)
• Nickel plating
• Passivation
