EMC & Thermal Management
Extruded heatsinks are the most commonly used type for thermal management, both in natural and forced convection.
2. Water cooled heatsinks Water cooled heatsinks are highly efficient and provide reliable thermal performance for high power modules. Water cooled heatsinks provide numerous advantages over air cooled heatsinks, including higher thermal conductivity, greater heat capacity and improved absorption, ideal for transportation, lasers, medical equipment and electronic equipment.
3. Thermal interface materials (TIMs)
Thermal interface materials bridge the gap between components and heatsinks, reducing thermal resistance and improving conductivity. GD Rectifi ers supplies high- performance thermal paste, enabling optimal heat transfer in tightly packed systems.
4. AC and DC fans
Designed and built for engine cooling, ventilation, air conditioning, heating and refrigeration markets. Axial and centrifugal
backward curved fan styles are popular choices.
5. Thermal trips
A range of surface mount bimetallic thermal trips designed for protection of power semiconductor components against overtemperature, varying from 40-230°C, are ideal for heaters, cooling fans and heatsinks.
A pioneering approach GD Rectifiers adopts a consultative approach, the company doesn’t just distribute off-the-shelf products; they partner with customers to develop customised solutions that meet exact specifications including prototyping, in- house CNC machining, technical support and after-sales service.
1. Custom engineered heatsinks with precision machining
As a designer and manufacturer of bespoke solutions tailored to complex or unique cooling requirements, GD Rectifiers’ heatsinks are optimised for high-power semiconductors, space-restricted enclosures and application-specific geometries.
2. Advanced liquid cooling solutions As power densities increase, especially in sectors like electric vehicles, renewable energy and rail, liquid-cooled heatsinks offer a step change in performance over traditional air cooling.
3. Integration of thermal interface materials (TIMs)
Thermal interface materials (TIMs) significantly reduce thermal resistance between components and heatsinks, ensuring maximum heat transfer with minimal footprint, supporting more compact electronics and enabling high performance under tight constraints.
4. Smart thermal control components Temperature sensors, thermistors and thermal fuses integrate into larger control systems and allow for real-time temperature monitoring, predictive thermal management and adaptive fan control and load shedding.
5. Integrated power and cooling solution Power semiconductors, assemblies and rectifiers enable customers to integrate
cooling directly into the power system design. This holistic approach reduces design cycles, improves compatibility and enhances overall system effi ciency.
6. Sustainability and effi ciency focus Efficient thermal management systems reduce energy waste through conduction and dissipation, component failure by minimising electronic waste and need for oversized cooling systems, saving on materials and space.
GD Rectifiers stands at the forefront of thermal management solutions, combining decades of expertise with a broad portfolio of products that meet the demands of today’s focus on performance, efficiency and cutting-edge cooling methods. Every application is unique with custom thermal management requirements: GD Rectifi ers collaborates with designers and engineers to provide tailored solutions. With a commitment to sustainability, GD Rectifi ers is paving the way for a future where thermal management is not just an after-thought but a necessity in the initial design process.
