Custom Sheet Metal Thermal Solutions by SanJun Hardware

In high-power industrial and outdoor setups, heat control often determines how long gear lasts and how reliably it works. Too much heat brings throttling, failed parts, and expensive stops. As an integrated custom sheet metal enclosure manufacturer, Ferretería SanJun provides end-to-end custom sheet metal thermal solutions that tackle hard heat problems while keeping structure and protection solid.

Thermal Engineering Excellence in Custom Sheet Metal Enclosures

Before exploring our real-world thermal case studies, it is essential to understand the engineering core that drives our manufacturing capabilities. We integrate custom structural design, precision CNC fabrication, and thermal optimization into a seamless service workflow for demanding thermal management enclosure projects.

  • Rapid Prototyping & Fast Turnaround: We deliver 24-hour DFM drawing evaluations and formal quotes, transitioning from 3D CAD models to functional prototype thermal management enclosure solutions in days.
  • Multi-Domain Industry Proven Track Record: Our custom sheet metal thermal solutions support electric vehicles, battery energy storage systems, outdoor digital kiosks, and data communication hardware.

Case Study 1: 160kW DC Fast Charger Cabinet Airflow Redesign

High-power EV fast charging infrastructure generates substantial thermal loads within compact footprints. Poor ventilation inside a DC fast charger enclosure can cause power modules to overheat and trigger performance throttling under peak summer conditions.

160kW DC fast charger enclosure airflow redesign for thermal management

Eliminating Thermal Throttling in High-Power EV Fast Chargers

To overcome chronic heat accumulation in a customer’s outdoor charging station, our engineering team conducted a comprehensive EV charger enclosure thermal management redesign for its DC Charging Pile Enclosure.

  • Engineered Louver Structure: Replaced standard side vents with angled, rain-resistant louver arrays designed to increase intake airflow while maintaining outdoor protection.
  • Segregated Cold/Hot Air Channels: Internal sheet metal baffles reduced hot-air recirculation and directed cooler airflow toward power conversion modules.
  • EV Charger Enclosure Thermal Management Results: The redesigned 160kW EV charger enclosure reduced internal operating temperatures and prevented thermal power throttling during high-load operation.

For a high-output DC fast charger enclosure, controlled airflow routing is often as important as total vent area.

Case Study 2: IP65 Outdoor BESS Liquid Cold Plate Integration

Battery Energy Storage Systems require stable internal temperatures to protect battery performance and system reliability. Maintaining sealed outdoor protection while removing concentrated heat makes energy storage cabinet thermal management a demanding engineering task.

Dual-Chamber Thermal Isolation for Energy Storage Systems

Our client needed an advanced energy storage cabinet thermal management system capable of supporting dense battery racks in demanding outdoor conditions.

  • Liquid Cooling Enclosure Integration: We engineered structural mounting frames and quick-connect cold plate brackets to support liquid cooling enclosure integration inside the Energy Storage Cabinet (BESS).
  • Dual-Compartment Architecture: High-voltage electrical components were separated from battery modules using sealed internal sheet metal partitions, improving routing and system organization.
  • IP65 Enclosure Thermal Management Results: The resulting liquid-cooled BESS enclosure combined sealed construction with integrated liquid cooling to support temperature control without sacrificing environmental protection.

Effective IP65 enclosure thermal management requires cooling paths that do not compromise the sealed barrier against dust and water.

Case Study 3: High-Nit Sunlight-Readable Digital Signage Housing

Outdoor displays face intense solar loading, while high-brightness backlights generate additional internal heat. Without proper sheet metal enclosure thermal management, screen panels can suffer temporary blackouts, reduced brightness, or accelerated component degradation.

Mitigating Solar Heat Gain in High-Brightness Outdoor Displays

For a municipal smart-city deployment, SanJun Hardware developed a specialized high-brightness digital signage enclosure designed for continuous outdoor operation.

  • Double-Walled Sun-Shield Structure: Fabricated an outer aluminum sunshade with an insulating air gap to reduce direct heat transfer into the display housing.
  • Cross-Flow Heat Sink Integration: Dedicated heat dissipation channels and temperature-controlled fan trays were incorporated behind the high-brightness panel.
  • Sunlight Readable Display Enclosure Results: The optimized sunlight readable display enclosure reduced solar heat buildup and supported more stable display operation in direct sunlight.

For outdoor kiosks, a high-brightness digital signage enclosure must address both internal electronic heat and external solar radiation.

Case Study 4: 2U High-Density Telecom Server Chassis Airflow Optimization

Enterprise data hubs and 5G edge computing systems demand maximum processing density in minimal rack space. Standard 2U enclosures often suffer from high static pressure and localized hot spots, making 2U server chassis airflow optimization essential.

Optimizing Pressure Drop and Airflow Channels in Compact Rack Enclosures

A telecom client required customized sheet metal enclosure thermal management for next-generation rack server equipment.

  • Precision Hexagonal CNC Perforations: Redesigned the front bezel of our Network Device Chassis with high-open-area perforations to improve intake airflow without compromising structural rigidity.
  • Internal Air Baffles & Heat Sink Mounts: Custom-folded air guides directed high-speed airflow across processor and power zones.
  • 2U Server Chassis Airflow & High Density Server Chassis Cooling Results: Improved 2U server chassis airflow reduced internal resistance and supported more effective high-density server chassis cooling around heat-sensitive components.

For compact servers, high-density server chassis cooling depends on controlling airflow direction rather than simply adding larger fans.

Partner with SanJun Hardware for Reliable Custom Thermal Solutions

When off-the-shelf cabinets fail to meet demanding thermal and environmental specifications, tailored custom sheet metal thermal solutions can provide greater control over airflow, cooling integration, and enclosure architecture.

Preguntas frecuentes

Q: Why is sheet metal design critical for thermal management in sealed outdoor enclosures?

A: A custom thermal management enclosure can integrate air baffles, louvers, double-wall solar shielding, cold plates, or heat exchangers while preserving structural and environmental protection requirements.

Q: What is the difference between air cooling and liquid cooling enclosure integration in energy storage systems?

A: Air cooling shifts heat with steady airflow. Liquid cooling enclosure integration moves heat through cold plates and coolant loops instead. A liquid-cooled BESS enclosure handles higher thermal loads more effectively in tight spaces.

Q: How does enclosure thermal design prevent thermal throttling in high-power DC fast chargers?

A: Good EV charger enclosure thermal management sets up clear intake and exhaust routes. It cuts hot-air recirculation and guides airflow straight to the hottest power modules inside the 160kW EV charger enclosure.

Q: Can an enclosure support thermal management without losing IP65 protection?

A: Yes. IP65 enclosure thermal management often relies on sealed dual-chamber designs or closed-loop heat exchangers. Liquid cooling systems can also pull heat away while electronics stay shielded from dust and water.

Q: What should buyers evaluate when choosing a custom sheet metal enclosure manufacturer?

A: Look at thermal design experience, DFM support, and how fast the supplier can prototype. Check build precision, sealing know-how, and track record with custom sheet metal thermal solutions in EV charging, BESS, displays, and server work.
