Why Direct-to-Chip Fluid Filtration is Essential

​

Direct-to-Chip cooling systems, which circulate various cooling fluids directly over heat-generating components, are highly effective but also vulnerable to particulate contamination. Microchannel cold plates and quick connects are particularly sensitive to even the smallest particles, which can obstruct fluid flow, leading to system inefficiencies, leaks, or even failure. Effective filtration is crucial to:

​

• Protect Critical Components: High-performance filters prevent particles from entering the cooling system, safeguarding delicate microchannels and ensuring that the cooling loop remains free from blockages and contaminants.

• Maintain System Efficiency: Clean cooling fluids are essential for maintaining optimal heat transfer, ensuring that DTC systems operate at peak performance.

• Extend Equipment Life: By removing contaminants, filtration extends the life of cooling components, reducing the risk of wear and tear, and minimising maintenance requirements.

 

Optimized Filtration Systems for Different Fluid Types

​

• Low Conductivity Water (LCW) Filtration: In LCW-based DTC systems, filtration systems are designed to capture particles based on the sensitivity of the cooling loop’s components. A side stream filtration approach is recommended, filtering approximately 10% of the heat transfer fluid flow. A filtration grade of 5 microns or less ensures that particulates do not become trapped within the cold plate microchannels, maintaining system integrity.

• Propylene Glycol Fluid Filtration: For DTC systems using propylene glycol-based fluids, a similar side stream filtration approach is recommended, targeting a 5-micron filtration grade. Additionally, inline filters in Coolant Distribution Units (CDUs) with a rating of 20-50 microns provide an extra layer of protection for heat exchangers and quick connects.

• Dielectric Fluid Filtration: Dielectric fluids, which resist biological growth, corrosion, and residue formation, require minimal filtration, typically at a 100-micron level. This effectively captures larger particles that could block fluid pathways, ensuring smooth operation. During system loading or cleaning, additional filtration may be necessary to remove contaminants introduced during these processes.

 

Ensuring System Integrity
