100% HOMOGENEOUS COPPER/BRASS LOOP ELIMINATES GALVANIC CORROSIONServer and enthusiast liquid loops utilize copper CPU/GPU cold plates. Mixing aluminum radiators with copper water blocks creates rapid galvanic corrosion that clogs microscopic 0.1 mm0.1 mm cold plate channels. CSTHEATEXCHANGER full copper/brass construction guarantees 100% chemical stability and zero galvanic sludge formation.
A leading cause of water cooling leaks is user over-tightening of fan mounting screws, driving the screw tip directly into fluid channels. CSTHEATEXCHANGER integrates hardened steel screw guard plates beneath every fan mounting hole, completely shielding copper tubes from accidental puncture.
Every custom liquid cooling radiator built in our Changzhou plant undergoes rigorous quality assurance protocols:
CSTHEATEXCHANGER FACTORY QUALITY & EXPORT WORKFLOW
[STEP 1: 100% PRESSURE & HELIUM MASS SPECTROMETER LEAK TESTING]
• Hydrostatic proof testing up to 0.5 MPa (72.5 psi) verifying brazed joint integrity.
• High-vacuum mass spectrometer helium leak testing (< 1x10⁻⁶ mbar·l/s).
─────────────────────────────────────────────────────────────────────────────
[STEP 2: TRIPLE-STAGE ULTRASONIC DEIONIZED FLUSH & CLEANLINESS AUDIT]
• Acid pickling, ultrasonic degreasing, and deionized water rinsing (< 5 mg/m²).
• Eliminates all flux residues, ensuring coolants and dyes remain crystal-clear.
─────────────────────────────────────────────────────────────────────────────
[STEP 3: REINFORCED SEAWORTHY EXPORT CRATING & OEM PACKAGING]
• Custom retail packaging or heavy master cartons with protective closed-cell foam.
• Export palletizing with moisture-barrier film for global containerized shipping.(Note: The following engineering parameters represent standard manufacturing design envelopes. Radiator lengths, thicknesses, port quantities, fin densities, and exterior paint finishes are customized to OEM client specifications.)
