Brass / 6061 Aluminum Alloy |
Nitrile Butadiene Rubber (NBR) |
Moderate cost, excellent machinability, compatible with water-glycol coolant; easy assembly and disassembly, meeting maintenance requirements |
System working pressure ≤ 3.0 MPa; avoid long-term high-temperature (＞100℃) working conditions; regularly inspect seal aging |
| New energy vehicle power battery liquid cooling circuit |
304/316 Stainless Steel |
Fluororubber (FKM/Viton) |
High pressure resistance (3.0–6.0 MPa), vibration and impact resistance; wide temperature tolerance, suitable for complex automotive working conditions |
Comply with ISO 16028 automotive industry standards; avoid contact with strong corrosive media other than oil-based coolants |
| Outdoor charging pile liquid cooling system |
316 Stainless Steel / Glass Fiber Reinforced PA66 |
Fluororubber (FKM/Viton) |
316 stainless steel resists outdoor humid corrosion; engineering plastic features light weight and good insulation |
Meet IP67 or higher protection level; replace with Silicone Rubber (VMQ) seals in low-temperature areas (＜-20℃) |
| High-temperature liquid cooling system for industrial equipment (e.g., laser equipment) |
316 Stainless Steel |
Perfluoroelastomer (FFKM) |
Ultra-high temperature resistance (≤200℃), compatible with strong corrosive coolants; stable sealing performance |
High cost, only suitable for high-end industrial scenarios; avoid seal surface wear caused by frequent plugging and unplugging |
| Portable liquid cooling for consumer electronics (e.g., gaming PCs) |
Polyoxymethylene (POM) / Aluminum Alloy |
Silicone Rubber (VMQ) |
Light weight, excellent insulation; resistance to extreme low temperature, suitable for compact space of small equipment |
Only for low-pressure (≤1.0 MPa), normal/low-temperature working conditions; avoid contact with oil-based coolants |

High Machining Precision:
Adopting the new SuperSpark4 and IES (Intelligent Expert System) technologies, we provide advanced adaptive power supply and jump control to stabilize the EDM process and improve machining precision simultaneously. Equipped with advanced ultra-surface and ultra-edge generator technologies, the workshop is capable of achieving excellent surface finish and metallurgical quality.
Liquid Cooling System Technology
High-power liquid cooling systems require heat sinks capable of rapid heat absorption. Leveraging the high specific heat capacity of liquids, our systems transfer large amounts of heat through liquid flow, capable of dissipating heat ranging from several hundred watts to over one kilowatt.
Liquid Cold Plate Varieties
- Buried-tube Liquid Cold Plate: Fabricated by grooving plates, burying and welding copper tubes inside, then hermetically sealing via welding. Ensures reliable liquid tightness, operational safety, and high flatness for excellent thermal contact.
- Inserted-tube Liquid Cold Plate: Manufactured by embedding copper tubes onto aluminum plate surfaces using welding or bonding processes, with strict flatness control for minimal thermal resistance.
- Channel-type Liquid Cold Plate: Internal flow channels formed on copper or aluminum substrates through drilling, extrusion, and precision machining, sealed via friction welding or high-temperature brazing.
- Liquid Cooling Block: For high-power chip heat dissipation with internal flow channels created through skiving fin technology to maximize heat exchange surface area.
