제품 개요 및 2025년 시장 관련성

Silicon carbide (SiC) modular cooling systems with integrated heat spreaders are engineered to unlock compact, high-power-density designs across Pakistan’s textile, cement, 강철, and emerging industrial sectors. By combining high-thermal-conductivity spreaders, liquid or sealed forced-air modules, and SiC-optimized thermal interfaces, these systems maintain device junction temperatures up to 175°C while sustaining rectification efficiencies above 98%. The result is 30%–40% smaller cooling hardware, stable operation in high-temperature and high-dust environments, and >50% reductions in thermally driven failure rates.

In 2025, plants in Punjab and Sindh are upgrading to SiC rectifiers, active front ends, and multi-pulse bridges to counter grid volatility and improve energy efficiency. Thermal constraints remain the limiting factor to power density and uptime. Modular cooling systems tailored for SiC—featuring AlN/Si3N4 substrate stacks, sintered interfaces, and integrated spreaders fabricated from copper composite or graphite-based materials—deliver uniform heat flux distribution across device clusters, enabling tighter cabinet layouts and higher current density. These systems integrate sensors for flow, temperature, and differential pressure, expose KPIs to SCADA via OPC UA/MODBUS/PROFINET, and align with IEC 62477-1 (safety) and IEC 61000 (EMC) deployment practices while contributing to ISO 50001 and ISO 14001 reporting.
