Mining BESS cooling for high-ambient and remote power systems
Mining BESS cooling has to hold battery and PCS temperatures through 45 °C+ summers, red dust and long gaps between service visits. ToneCooling designs liquid cold plates, manifolds and liquid cooling units for mine-site batteries, off-grid hybrid systems and fleet chargers.
Site conditions that change the cold plate design
| Ambient | Summer peaks above 45 °C narrow the coolant approach margin |
| Dust | Sealed enclosures push heat into the liquid loop |
| Distance | Every failure means a fly-in service trip |
| Vibration | Skid- and vehicle-mounted equipment loads the joints and ports |
Where is mining BESS cooling used?
Mine-site BESS & hybrid off-grid
Battery and PCS cold plates, manifolds and liquid cooling units for diesel-displacement and solar-hybrid systems at remote camps and processing plants.
Cabinet coolingFleet & underground chargers
Power-module cold plates for DC chargers serving electric haul, light-vehicle and underground fleets.
Charger cold platesIndustrial UPS & DC systems
Inverter and rectifier cold plates for UPS and DC power at processing plants, substations and comms sites.
Power electronicsMining vehicle drives
IGBT and MOS cold plates for traction converters in electric mining trucks and loaders.
MOS cold plateHow do high-ambient mine sites change BESS cooling?
These are the questions we raise in DFM review for remote-site programmes. Each one ends up as a line on the drawing or the test plan.
| Topic | What we check | Where it lands |
|---|---|---|
| Approach temperature | Cold plate performance at the worst-case coolant inlet, not the nameplate inlet | CFD load case and acceptance test |
| Coolant | Glycol concentration, inhibitors and compatibility with aluminium in the loop | Material spec and test fluid |
| Mixed metals | Galvanic risk when copper and aluminium parts share one loop | Material selection and loop notes |
| Pressure & leaks | Proof pressure margin and helium leak rate for a sealed, unattended asset | Test plan and per-lot records |
| Vibration & mounting | Port strength, fastener pattern and plate stiffness on skids and vehicles | Drawing notes and mounting interface |
| Heat rejection | Liquid cooling unit capacity at peak site ambient, enclosure rating and corrosion class for dusty or coastal sites | Unit selection: IP54, C4 anti-corrosion. Liquid cooling units |
| Serviceability | Spares strategy, connector type and swap time in the field | Spares list and connector spec |
How is supply planned for remote mining projects?
- Prototype first. You can test single-piece custom samples in your enclosure before you commit to a project build.
- Revision-locked records. Leak, pressure and ΔP data are tied to each drawing revision for your project handover file.
- Spares built with the order. Field spares come from the same production lot.
- Australian contact. The Carlton VIC team handles documentation, customs and after-sales.
Who we work with
We supply the equipment manufacturers and integrators who build systems for mine sites. We don’t contract directly as a site electrical or installation contractor.
A cold plate quotation is not approval of the complete installation. Design, installation and compliance responsibility stays with the system designer and the licensed installer.
Mining and remote power cooling questions
What ambient temperature should we design for?
Use the worst-case site figure in your project specification. For many Pilbara and Goldfields sites that means design ambients well above 45 °C. We run the CFD load case at the coolant inlet your chiller or dry cooler can actually reach on that day.
Aluminium or copper for a remote BESS loop?
Battery and PCS plates are usually aluminium for weight and cost. If any copper part shares the loop, we flag the galvanic risk and the coolant inhibitor requirements in DFM.
Can you support equipment for underground mining?
We supply cold plates to the charger or equipment manufacturer. Underground certification of the finished equipment stays with that manufacturer. We provide the component documentation they need.
What test records come with each lot?
Helium leak and proof-pressure results as standard. Hydraulic ΔP and thermal checks are added where the acceptance plan calls for them. Every record is tied to the drawing revision.
How does battery cooling fit a mine-site microgrid?
In a mine-site microgrid, the battery and PCS smooth solar and diesel output and carry the load during peaks, so they cycle hard in the hottest part of the day. Liquid cold plates and a correctly sized liquid cooling unit keep cell and IGBT temperatures in range through those duty cycles.
Tell us about the site, not just the part
Send the equipment drawing along with the site ambient, coolant and duty cycle. Your DFM response will cover the high-ambient checks, not only the nameplate rating.
