Liquid Cooling Equipment
Liquid cooling equipment housings made via precision zinc alloy die casting are designed to support components such as cold plates, fluid channels, connectors, and pump mounts. These enclosures combine the thermal conductivity and shielding advantages of zinc alloys with tight sealing and structural robustness to handle liquid cooling applications for high-performance electronics.
They are widely applied in data center servers, 5G base stations, power electronics, automotive battery thermal management, and industrial control systems, where efficient heat dissipation and long-term reliability are critical. The zinc die-cast structure ensures high dimensional accuracy, strong mechanical integrity, and stable performance under continuous fluid flow and temperature variation.

Series of Liquid Cooling Enclosures
Material
Surface Treatment
Because these housings will have contact (or near contact) with liquid, moisture, or humid environment, and need sealing surfaces, typical treatments include:
|
Treatment Type |
Description / Application |
Typical Thickness or Property |
|
Electroless Nickel (Ni-P) |
Uniform plating over internal fluid channels, ports and sealing faces to resist corrosion |
~8-20 µm |
|
High-Phosphorus Nickel |
For especially corrosive environments; improves resistance to pitting and corrosion from coolant |
Dense, amorphous nickel layer; ≥ 120 h salt spray without significant corrosion under suitable sealing |
|
Copper + Nickel Stack |
Copper underlayer (for conductivity) + Nickel overlay to improve corrosion and wear resistance |
Copper ~5-15 µm + Nickel 8-20 µm |
|
Surface Machining / Precision Grinding of sealing faces |
Ensure flatness and sealing surface finish to meet leak-rate requirements |
Ra ≤ 1.6 µm, flatness ≤ 0.05 mm |
|
Protective Coating or Sealant on external surfaces |
To avoid external corrosion or oxidation where exposed |
Thin passivation or clear coating, thickness ~2-5 µm as needed |

Quality and Certification
Manufactured under ISO 9001 quality system; alloy and plating vendors certified.
Certified compatibility with coolant materials; no leachable or toxic plating constituents.
Leak testing and pressure rating verified per customer requirements. RoHS / REACH compliance for all materials and surface finishes. Full documentation: material certificates, plating thickness reports, dimensional inspection reports (CMM), pressure/leak test results.
Packaging and Logistics
Packaging: Each liquid cooling equipment enclosure is wrapped in moisture-proof plastic, individually cushioned with foam blocks or mold-fit protective packaging to protect port flanges and sealing faces. They are then boxed in heavy-duty double-wall cartons, labeled with product type, size, batch number, and handling instructions (“Fragile: sealing surface”). Secure them on pallets for large quantities.
