I’m Xin Qiang, an HVAC and thermal simulation engineer with 12 years of design experience across large public, healthcare, and commercial buildings. Over the last three years, I’ve focused on data-center thermal management—especially cold-plate liquid cooling, closed-loop dry-cooler systems, and heat recovery—working from system design through detailed verification.
I run end-to-end 3D CFD studies in ANSYS Fluent (from geometry/meshing to solve, verification, and clear reporting) and perform system-level airflow simulation with 6SigmaDCX. I deliver results with explicit verification such as heat-balance closure, mesh sensitivity, and cross-checks, and I’m comfortable coordinating remotely with English-first written communication on HVAC/MEP and CFD freelance scopes.
From CAD-to-Revit-MEP_Portfolio_EN_V1.5 — model details sample. 2D MEP drawings turned into a connected Revit model: ductwork with takeoffs, chilled water branches, fire main, power and low-voltage trays. Source portfolio: CAD to Revit MEP (EN V1.5). Remote modeling sample — coordination/BIM support, not a local stamp.
From Portfolio_Thermal_CFD_EN_V1.2 — Liquid Cold Plate conjugate heat transfer sample. Copper plate with multi-pass serpentine channel and chip heat load; temperature field and verification notes. Source portfolio: Thermal Simulation & CFD (EN V1.2). Remote engineering sample — not a stamped PE report.
From Portfolio_Thermal_CFD_EN_V1.2 — Dry-Cooler Cluster Recirculation sample. Four 1000 kW V-type dry coolers side by side, 35°C ambient: calm vs. 3 m/s cross-wind. Intake temperature rise / recirculation risk with verification notes. Source portfolio: Thermal Simulation & CFD (EN V1.2). Remote engineering sample — not a stamped PE report.
From Portfolio_Thermal_CFD_EN_V1.2 — Data-Hall Airflow sample. Two rows, 20 racks (159 kW), raised-floor supply into the cold aisle. Open vs. contained comparison with temperature/velocity fields and verification notes. Source portfolio: Thermal Simulation & CFD (EN V1.2). Remote engineering sample — not a stamped PE report.
Focused on data-center thermal management for high-density modular racks, including cold-plate liquid cooling, closed-loop dry-cooler systems, and heat-recovery architectures. Performs system-level airflow simulations with 6SigmaDCX and runs end-to-end CFD studies in ANSYS Fluent (geometry/mesh/solve/verification/report). Supports remote project delivery with English reports and explicit verification (heat-balance closure, mesh sensitivity, and engineering cross-checks).
HVAC design work supporting large building projects, covering cooling/heating loads and air and water system design as part of MEP/thermal engineering deliverables.
HVAC/MEP design engineering across architectural projects, including cooling/heating load calculation, system layout, and coordination of HVAC deliverables.
