Ultra-Thin Stainless Steel Vapor Chamber Heat Spreader

1. Superior Uniform Temperature Control, Lower Battery Temperature Difference
Equipped with dense array micro-pillar capillary wick, the internal liquid backflow speed is increased by 45% compared with traditional mesh wick VC. It limits the temperature difference of the entire battery cooling plate within ≤3℃ under 5C fast charging conditions, effectively eliminating local hot spots, solving the core pain point of uneven heat dissipation of ordinary vapor chambers on the market. It greatly reduces battery aging rate and prolongs cycle life by over 20%.
2. Stainless Steel Shell, Outstanding Anti-Corrosion & Safety Performance
We select food-grade 304 stainless steel as the shell material, compared with pure copper vapor chambers easily oxidized and corroded by battery electrolyte vapor, our VC owns excellent acid & alkali resistance, anti-rust and leakage-proof capacity. It avoids hidden danger of short circuit caused by shell corrosion, fully meeting strict vehicle-grade safety standards for new energy batteries.
3. Precision One-Shot Forming, Complex Irregular Outline Customization Capacity
Adopt full-process CNC stamping + vacuum brazing integrated production line, can process special irregular contours, reserved positioning bumps and long flow channels in one molding. Most competitors can only produce simple rectangular VC; our flexible manufacturing realizes one-piece forming of complex battery structural plates without secondary splicing, reducing thermal resistance and assembly tolerance.
4. Ultra-Thin Lightweight Design, Higher Battery Pack Energy Density
Thickness range covers 0.3mm–1.2mm, the stainless steel base plate is thinner and lighter than thick copper VC with the same heat dissipation power. It saves internal space of battery pack, helps customers improve system energy density without sacrificing cooling performance, ideal for lightweight EV battery and compact household energy storage modules.
5. 100% Leakage Inspection & Stable Mass Production Consistency
Every finished vapor chamber passes 3 times vacuum helium leak detection + high-low temperature cycle aging test before delivery, zero leakage rate for mass shipment. Our factory owns automated sintering and brazing workshops, stable yield above 99.5%, avoiding unstable thermal performance caused by poor sealing of small peer manufacturers.
