HSE-B381-045H

CUI Devices's HSE-B381-045H delivers breakthrough thermal performance for data center applications in the Thermal - Heat Sinks category. Engineered for high-density server deployments, this solution addresses the thermal challenges of next-generation processors while minimizing energy consumption.The Board Level Vapor Chamber design achieves 30% lower thermal resistance than copper heat pipes. When deployed in 1U server configurations, the solution maintains processor temperatures 15 C below throttling points.Optimized for LGA 4677 sockets, the solution manages {Power Dissipation @ Temperature Rise} at server inlet temperatures up to 45 C. The thermal interface maintains performance through 50,000 insertion cycles.The Load Plate system provides uniform pressure distribution (75 5N) across the entire package area. The design prevents PCB warpage in multi-layer server motherboards.Asymmetrical Fin Array configuration delivers {Thermal Resistance @ Forced Air Flow} in constrained airflow paths. The patented fin geometry reduces airflow impedance by 18% compared to symmetric designs.The 1.500" (38.10mm) dimension fits standard 19 rack server footprints while allowing for optimal airflow management. Computational fluid dynamics confirms no hot spot formation in rack-level simulations.With 1.772" (45.00mm) coverage, the solution accommodates dual-processor configurations without thermal interference. Thermal imaging shows less than 2 C variation between adjacent CPUs.Precision 0.500" (12.70mm) ensures compatibility with 40mm high-speed fans (15,000 RPM). The fin density is optimized for acoustic performance (<35dBA at 1m distance).Rated for 9.9W @ 75°C in 45 C ambient conditions, the design includes PUE-optimized performance curves. Thermal models account for recirculation effects in hot aisle containment systems.The 2.63°C/W @ 200 LFM performance is validated under ASHRAE TC9.9 Class A3 conditions. The design maintains stability at airflow rates from 10-25 CFM.The 7.58°C/W specification enables emergency operation during cooling system failures. The design maintains processors below 90 C for 15 minutes without airflow.Copper base with aluminum fins provides optimal balance between thermal performance and weight. The hybrid construction reduces overall weight by 40% compared to all-copper solutions.Nickel-plated surface ensures long-term reliability in data center environments. The finish resists sulfurization and maintains emissivity >0.85 after 5 years of operation.
