What information does ToneCooling Australia need for a cold plate RFQ?

Required RFQ inputs are: (1) target platform or application (GB200, BESS module, IGBT inverter, etc.); (2) thermal load and inlet temperature; (3) coolant type and flow rate; (4) mechanical envelope and port locations; (5) quantity and programme schedule; (6) applicable AS/NZS or industry standards; (7) PPAP level required (if any); (8) target Australian deployment site.

How long does it take to get a cold plate quote?

Carlton-coordinated engineering response is structured for an initial reply within two Australian business days (AEST/AEDT 09:00-17:30, Mon-Fri) once the RFQ inputs are received. A detailed engineering response including DFM commentary, CFD assessment, and compliance scope is typically returned after the project intake call. Commercial terms are agreed by separate written commercial agreement.

Can I send a CAD drawing or thermal model in the RFQ?

Yes. CAD drawings (STEP, IGES, native), thermal models (CFD setup files where available), and 2D drawings (PDF, DWG) are all accepted as RFQ inputs. Drawings should specify mechanical envelope, port locations, mounting interface, and any controlled dimensions. NDA execution is available before sharing any design IP. info@tonecooling.com.au is the primary RFQ intake address.

RFQ Input Checklist for Liquid Cold Plates

What to send when requesting a liquid cold plate quote. The more complete your RFQ, the faster the engineering response cycle. A complete RFQ — TDP map, target ΔP and flow rate, qualification scope, lead time — receives a Carlton-coordinated response within 24 working hours, with technical review by the Huizhou design and engineering team. Includes a thermal sensitivity table, process recommendation, and draft quote in AUD.

Engineering Reference & Standards

What is the RFQ Input Checklist for Australian liquid cold plate programmes?

The RFQ Input Checklist is the technical brief Carlton needs from your engineering team to accelerate the response cycle. Inputs map directly to Open Compute Project DC-MHS manifold specs (for AI server programmes), ASHRAE TC 9.9 thermal-acceptance envelope, AS/NZS scope mapped to Standards Australia, and platform references such as the NVIDIA GB200 NVL72 platform.

What does each RFQ input field tell ToneCooling Australia?

9 RFQ input fields, each tied to a specific engineering decision Carlton + Huizhou needs to make. Sending all 9 upfront accelerates the engineering response from typical 2-week back-and-forth to a single DFM session within the same week.

RFQ INPUT 1

Application + platform

GB200 / SP5 / TC-1P104S BESS / IGBT inverter / fibre laser / medical / custom. Determines product family routing.

RFQ INPUT 2

TDP map / heat load

W per die or W per cell. Drives channel-topology and substrate selection. Bianca module example: 2,700 W; 1P104S BESS cell example: 15 W per cell.

RFQ INPUT 3

Target ΔP and flow rate

CDU pump curve or BMS pump curve. Defines ΔP envelope (typically 20–80 kPa) and flow rate (5–25 L/min for AI server, 8–15 L/min for BESS module).

RFQ INPUT 4

Coolant chemistry + inlet T

50/50 EGW · 25 % PG · DI water. Inlet temperature class: ASHRAE W32 (32 °C) or W40 (40 °C). Determines material substrate compatibility.

RFQ INPUT 5

Mechanical envelope + ports

Cold plate footprint, depth, mounting interface, port locations and orientation. CAD format: STEP / IGES / native.

RFQ INPUT 6

Volume + programme schedule

Prototype quantity · production volume · programme go-live date. Drives lead-time planning and whether prototype tooling is needed.

RFQ INPUT 7

CDU model or BMS pump curve

For AI server: Vertiv / CoolIT / Stulz / Motivair model. For BESS: BMS pump curve. Determines hydraulic compatibility.

RFQ INPUT 8

AS/NZS + qualification scope

Applicable AS/NZS standards (5139 / 4777.2 / 60068-2-14 / 60529) and PPAP level required. Determines documentation scope.

RFQ INPUT 9

Australian deployment site context

AU state, climate context (coastal / arid / urban), sovereign cloud / colocation / mining context. Drives material selection (e.g. ISO 9227 salt-spray for coastal sites).

A short technical checklist — fill what you can in your RFQ to accelerate the engineering response. Required fields are marked. Recommended fields reduce back-and-forth clarification cycles.

Application RequiredAI server / BESS / power electronics / heavy-EV / industrial / custom. Routes RFQ to the correct Huizhou engineering team and reference product family.
TDP map RequiredW per die (AI server / power electronics) or W per cell (BESS) with platform / cell layout. Sets thermal envelope for CFD modelling.
Target ΔP and flow rate Requirede.g., ≤ 25 kPa @ 10 L/min on 50/50 EGW. Sets hydraulic envelope for channel topology selection.
Coolant chemistry Recommended50/50 EGW (default) · 25% PG · water-only · other. Sets thermophysical properties for CFD simulation.
Inlet temperature window RecommendedASHRAE W32 (20–32 °C) or W40 (20–40 °C) or programme-specific. Sets boundary condition for AU climate envelope.
CDU model or BMS pump curve RecommendedVertiv / CoolIT / Stulz / Motivair (AI server) or BMS pump curve (BESS). Aligns cold plate ΔP with system pump curve.
Lead-time requirement RecommendedProgramme-flexible / standard / expedited / engineering preview. Helps the engineering team plan the response track.
Qualification scope RecommendedStandard validation pack · AS/NZS 60068-2-14 thermal cycling · ISO 9227 salt-spray (coastal) · PPAP Levels 1–5 · customer-specific qualification programme. Drives validation documentation tier.

How it accelerates the response. A complete technical RFQ enables the Carlton VIC team to route to the correct Huizhou engineering team and provide a Carlton-coordinated engineering response — including a thermal sensitivity table, process recommendation, and draft quote in AUD. NDA execution and commercial-terms discussion happen after first contact.
