Pin-Fin Extruded Aluminum Heat Sink | CNC Machined For Energy-Storage Battery Cabinet
1. Detailed Description Of Pin-Fin Extruded Aluminum Heat Sink for Energy-Storage Battery Cabinet
1.1 Core Design & Craftsmanship
Our CNC Machined Pin-Fin Extruded Aluminum Heat Sink for Energy-Storage Battery Cabinet adopts integrated aluminum extrusion molding technology, paired with high-precision CNC secondary machining, abandoning traditional flat fin heat dissipation structure. The unique three-dimensional pin-fin layout maximizes the heat dissipation surface area per unit volume, greatly improving air convection efficiency and heat exchange speed. Different from ordinary stamped heat sinks, our extruded aluminum heat sink has an integrated seamless structure, no loose parts, stronger pressure resistance and durability, perfectly adapting to long-term uninterrupted working conditions of energy storage battery cabinets.
As a professional heat sink manufacturer and supplier, we select high-purity 6063-T6 aluminum alloy raw materials for all extruded aluminum heat sinks. This material features ultra-high thermal conductivity, light weight, and excellent corrosion resistance. After precision CNC machining, the base flatness of the heat sink is controlled within ±0.02mm, ensuring full close contact with battery module heating parts, minimizing thermal resistance, and realizing rapid heat conduction and diffusion. The surface adopts anodizing anti-oxidation treatment, which effectively resists dust, moisture, and electrochemical corrosion in complex industrial environments, and long-term maintains efficient heat dissipation performance.
1.2 Application-Oriented Performance Optimization
Aiming at the high-power and long-operation characteristics of energy storage battery cabinets, our CNC machined pin-fin heat sink is optimized in structural design: the dense and uniform pin-fin arrangement effectively breaks the air boundary layer, avoids heat accumulation in the closed cabinet, and reduces the overall operating temperature of the battery pack. The lightweight aluminum alloy design will not increase the load of the battery cabinet, and the rigid integrated structure can resist vibration and impact during equipment operation and transportation, reducing the failure rate of thermal components. All products comply with industrial environmental protection and safety standards, suitable for indoor and outdoor energy storage cabinet scenarios.

3. Advantages Of Pin-Fin Extruded Aluminum Heat Sink for Energy-Storage Battery Cabinet
3.1 Superior Thermal Performance, Stable Battery Operation
Our CNC Machined Pin-Fin Extruded Aluminum Heat Sink adopts a three-dimensional pin-fin structure, which has a 30% larger heat dissipation area than traditional linear fin heat sinks of the same volume. As a professional heat sink manufacturer, we optimize the pin fin density and height through professional thermal simulation, effectively improving air circulation efficiency, quickly taking away heat generated by the energy storage battery during charging and discharging, avoiding battery thermal runaway, and ensuring the long-term stable operation of the energy storage cabinet system.
3.2 Precision CNC Machining, High Matching Degree
Different from ordinary extruded heat sinks, our products are processed by multi-axis CNC precision machining after extrusion molding. The base fitting surface is smooth and flat with tiny thermal resistance, which can perfectly fit the battery module. All mounting holes and positioning grooves are precisely opened by CNC, with high dimensional accuracy and no assembly deviation. As a reliablesupplier, we ensure every customized extruded aluminum heat sink can perfectly match different models of energy storage battery cabinets.
3.3 Durable & Environmentally Friendly, Low Maintenance Cost
Made of high-quality 6063-T6 aluminum alloy, the pin-fin aluminum heat sink has high strength, light weight, no deformation, and good shock resistance. After anodizing surface treatment, it has excellent moisture-proof, dust-proof and anti-corrosion capabilities, adapting to harsh industrial and outdoor energy storage scenarios. The integrated molding process eliminates the risk of fin falling off, with ultra-low failure rate and almost no later maintenance cost, helping customers reduce equipment operation costs.

FAQs
Can you supply custom extruded aluminum profiles with OEM drawings & precise tolerances?
Yes, we specialize in custom aluminum extrusion profiles based on 2D/3D drawings (STEP, IGS, DWG). We support complex cross-sections, strict dimensional tolerances (±0.1mm for critical parts), and tailored alloys (6063/6061/6082). We provide free mold design evaluation for bulk export orders of custom industrial aluminum profiles and architectural aluminum sections.
What surface treatments are available for export-grade aluminum profiles?
We offer full surface finishes for global markets: anodizing (clear/color), powder coating (RAL colors), electrophoresis, polishing, sandblasting, and fluorocarbon coating. All treatments enhance weather resistance, durability, and appearance for aluminum window profiles, curtain wall aluminum profiles, T-slot industrial aluminum profiles, and heat sink aluminum profiles for overseas buyers.
What is the range of custom size & cross-section for your export aluminum profiles?
We support custom size aluminum profiles for export with cross-sections from 10mm×10mm to 300mm×300mm, wall thickness 0.8mm–10mm, and length up to 6 meters (or cut to your required length). Available cross-sections include T-slot, hollow tube, L-angle, U-channel, and complex custom shapes (per 2D/3D drawings). Our precision aluminum extrusion dimensions (tolerance ±0.1mm) suit architectural curtain walls, industrial frames, and solar panel aluminum bracket profiles.
What’s the MOQ for aluminum profiles and can we mix different profiles in one container?
The standard MOQ is 500–1000kgs per profile; we accept lower trial quantities for new export customers. We support mixed container loading of various aluminum extrusion profiles (industrial, architectural, LED, door & window) to optimize shipping costs and reduce inventory pressure for importers.
How long is the lead time for custom aluminum profile extrusion & export shipment?
Standard stock aluminum profiles ship in 7–10 days. Custom aluminum profile extrusion with new molds takes 20–25 days (mold fabrication + production). Bulk export orders (FCL/LCL) arrange shipment in 25–35 days, with timely updates on production, inspection, and container loading for global buyers.
What packaging & shipping solutions do you offer for overseas aluminum profile orders?
We use export-standard packaging: pearl cotton, kraft paper, plastic film, and fumigated wooden crates/pallets to prevent scratches and damage during sea/air freight. We support FOB, CIF, CFR, and DDP terms, with professional loading plans to maximize container utilization for long aluminum profiles and irregular custom sections.
Do your aluminum profiles meet international export standards (CE, ASTM, AAMA, EN)?
All our industrial & architectural aluminum profiles comply with CE, EN755, EN14888, ASTM B221, AAMA, and RoHS directives. We provide full test reports, material certificates, CO, and commercial invoices to smooth customs clearance for aluminum profile exports to Europe, North America, Southeast Asia, and Oceania.
What testing do your export aluminum profiles undergo to ensure quality?
All profiles pass rigorous testing: dimensional inspection (CNC coordinate measuring machine), tensile/elongation tests (ISO 6892-1), salt-spray corrosion tests (1000+ hours, ASTM B117), surface finish adhesion tests (ASTM D3359), and color fastness tests (ISO 105-B02). For key projects, we provide third-party (SGS/BV/Intertek) test reports.
