Product Description
Liquid Cooled Cold Plate For Inverter (Inverter Liquid Cold Plate)
1. Product Overview
This liquid cooling component is specially designed for photovoltaic inverters, energy storage inverters, wind power converters and industrial frequency converters. It circulates coolant through internal flow channels to dissipate heat generated by core components such as IGBTs, SiC power modules, inductors and busbars, ensuring stable full-load operation of equipment. It is mainly manufactured by two processes: Friction Stir Welding (FSW) and vacuum brazing.
2. Main Applicable Processes & Features
2.1 Friction Stir Welding (FSW) Version (High-end Mainstream)
Adopting solid-state welding technology with no molten pool or pores. The weld strength reaches 90%–95% of the base material.
- High pressure resistance: Rated working pressure ≥ 1.5 MPa, excellent vibration resistance and thermal fatigue resistance.
- Minimal welding deformation and high surface flatness, delivering superior thermal contact with power modules.
- Ideal for applications requiring long service life and operating under severe vibration, such as outdoor facilities, vehicle-mounted systems, energy storage and wind power equipment.
2.2 Vacuum Brazing Version (Cost-effective Type)
- Mature process with high cost performance, suitable for low-pressure and static working conditions.
- Pressure resistance: 0.5–1.2 MPa; relatively large thermal deformation occurs during processing.
- Widely applied to indoor power frequency converters and general photovoltaic inverters.
3. Common Materials
Aluminum Alloy (Mainstream)
- 6061/6063: Optimal overall performance in strength, thermal conductivity and machinability, the first choice for general models.
- 1050/1070: Pure aluminum with higher thermal conductivity, for equipment with ultra-high heat dissipation requirements.
Copper Alloy
Features outstanding thermal conductivity, adopted for inverters with high power and high-density power modules.
4. Internal Flow Channel Types
- Serpentine Channel: For general high-power inverters, featuring uniform fluid flow and stable heat dissipation.
- Microchannel: Applied to compact inverters with high power density for higher heat exchange efficiency.
- Parallel Split Flow Channel: Enables zoned heat dissipation for multiple modules and ensures consistent temperature control.
5. Core Technical Parameters (Industry Standards)
- Standard test pressure: 1.0 MPa, no leakage after 30 minutes of pressure holding
- Operating temperature: -40℃ ~ +85℃
- Surface flatness (FSW process): ≤ 0.1 mm/m
- Applicable coolants: Ethylene glycol aqueous solution, pure water, dedicated cooling antifreeze
6. Typical Application Scenarios
Grid-tied PV inverters, string inverters, centralized inverters
Power Conversion Systems (PCS), inverter systems for energy storage containers
Wind power converters, locomotive traction inverters
Industrial frequency converters, servo drives, high-voltage frequency conversion equipment
7. Manufacturing Process (FSW Process)
Material cutting → Flow channel milling → Precision cleaning → Plate assembly & clamping → Friction stir welding → Post-weld finish milling → Hydraulic & air tightness testing → Surface treatment (Anodizing / Sandblasting) → Machining of mounting holes & ports → Final inspection
8. Selection Guidelines
- Outdoor power stations, wind power, energy storage and long-term vibration environments: Prioritize Friction Stir Welding (FSW).
- Indoor static equipment, cost-sensitive projects and low-pressure working conditions: Select vacuum brazing.
- High-power / high-heat generation equipment: Choose high-thermal-conductivity aluminum or copper materials combined with microchannel structure.
