BESS Module Liquid Cooling Plate Guide (1P104S Example)
A BESS module liquid cooling plate is designed for temperature uniformity and long-life reliability. The key CTQs are leak acceptance,
flatness/warpage, hole pitch for pack integration, and cleanliness to avoid ΔP drift. Use the inputs and checklist below to start a manufacturable RFQ.
BESS RFQ inputs table
| Input | Why it matters | Recommended note |
|---|---|---|
| Module drawing + mounting | Defines contact and datums | Keep-out + clamp points |
| Heat profile | Peak vs average load | Duty cycle, C-rate |
| Coolant + inlet temp | ΔP + corrosion behavior | PG% and min/max temp |
| Flow + allowable ΔP | Sets channel window | Budget per module |
| Ports/connection | Integration/serviceability | Thread/QD + orientation |
Integration checklist
- Confirm clamp/load path and interface material strategy.
- Confirm routing and service access (replaceability workflow).
- Confirm manifold balancing across parallel modules.
- Confirm leak test window, acceptance, and retest policy.
- Confirm coolant compatibility strategy (inhibitor + filtration + maintenance).

FAQ
What matters more for BESS: lowest temperature or uniformity?
Uniformity and repeatability are often more important for lifetime and safety margins.
How do we keep ΔP low on large plates?
Use parallel/hybrid paths and minimize restrictions; validate with ΔP–flow curves.
Do we need flatness requirements?
If contact is sensitive, yes—define flatness, datums, and measurement method.
What leak test method is typical?
Pressure decay is common for screening; select sensitivity based on risk.
How do we avoid flow imbalance across modules?
Manifold balancing is a CTQ; validate temperature uniformity under controlled load.
Can corrosion cause performance drift?
Yes—deposits raise ΔP and create hot zones. Define chemistry and maintenance assumptions.
What deliverables should we request?
Leak record, CTQ inspection (FAI/CMM), and optional ΔP–flow report.
What is the fastest way to start a quote?
Module drawing + heat profile + coolant/inlet temp + flow/ΔP + port constraints.
