Liquid Cooling Plate and Heat Sink for PV Inverters: Jindu's Precision Thermal Management
In the demanding photovoltaic (PV) industry, efficient thermal management is critical to maintaining system reliability and performance. Jindu delivers high-performance Liquid Cold Plate and Heat Sink solutions tailored for PV inverters, reducing IGBT junction temperatures by 15-25°C, improving system efficiency by 2-3%, and extending operational lifespan by over 30%. With advanced processes like vacuum brazing, friction stir welding (FSW), and skiving fin technology, Jindu ensures customized, reliable cooling for high-power applications.
Photovoltaic Industry Challenges: Key Thermal Management Pain Points
The photovoltaic sector faces escalating thermal demands due to increasing power densities and harsh operating environments. Effective heat dissipation is essential to prevent efficiency losses and component failures.
High Power Density Thermal Bottlenecks
Concentrated and string inverters now handle outputs from 100kW to 5MW, with IGBT heat flux exceeding 200W/cm². Traditional air cooling struggles to manage these loads, leading to hotspots and reduced reliability.
Efficiency and Lifespan Impacts from Elevated Temperatures
A 1°C rise in temperature can decrease inverter efficiency by 0.4-0.5%. Junction temperatures above 150°C accelerate device degradation, shortening system life and increasing maintenance costs.
Harsh Outdoor Conditions Exacerbating Heat Issues
In environments like deserts or high-altitude sites, ambient temperatures reach 50°C+, combined with dust accumulation and humidity corrosion, which compromise conventional cooling methods.
Limitations of Traditional Heat Sinks in MW-Scale Plants
Standard Heat Sink designs fall short in ensuring long-term stability for large-scale PV installations, necessitating advanced solutions like Liquid Cooling Plate for optimal performance.
Jindu's Solutions: Targeted Thermal Management for PV Applications
Jindu addresses these challenges with specialized Liquid Cold Plate and Heat Sink products, engineered for seamless integration into PV systems. As a leading provider of thermal solutions, Jindu offers OEM/ODM services with state-of-the-art manufacturing to meet precise client specifications.
Liquid Cooling Plate Solutions
Jindu's Liquid Cooling Plate directly interfaces with IGBT modules, supporting single-phase or two-phase cooling with thermal resistance below 0.05°C/W. For 1500V SiC modules, our plates achieve ΔT 10⁻⁹ mbar·L/s), durable surface treatment options like anodizing or electrophoretic coating, and broad coolant compatibility with water, 50% glycol, or Novec 7000.
High-Performance Heat Sink Solutions
For complementary or standalone use, Jindu's Heat Sink incorporates hybrid structures with skived fins, heat pipes, and bonded fins. Ideal for 30-100kW string inverters, these sinks optimize airflow through precise fin density (0.1-0.3mm spacing), enhancing heat dissipation efficiency. Manufacturing employs extrusion, skiving, and die-casting technology for superior structural integrity and thermal performance in natural or forced convection setups.
