- Calculation support based on cooling load or heat dissipation
- From prototype concept to production preparation
RAPID PROTOTYPE PATH
Start Prototype Review Before Tooling or Mass Production
CNC Sample Discussion
Review whether CNC sample components are suitable for early validation.
3D-Printed Fit-Up Models
Use concept or fit-up models to check structure, installation space and assembly direction.
7-Day Prototype Target
Fast-track sample support for eligible projects.
Engineering Feedback First
Receive technical review before sample fabrication or production planning.
EARLY-STAGE BUYER PROBLEMS
New Product Development Needs Faster Validation
We only have a concept or rough drawing.
Send the drawing, sketch, sample photo or application description. Domi can review what information is missing and recommend the next step.
We need to calculate based on cooling load.
Provide cooling capacity, heat dissipation, inlet/outlet temperature, airflow or liquid flow data. Domi can review early thermal design direction.
We need to confirm fit-up before tooling.
CNC samples or 3D-printed fit-up models can help check installation space, mounting position and structure before final production design.
We need a sample to show our customer.
Prototype samples can support buyer-side evaluation, project bidding, customer approval or internal engineering review.

CALCULATION AND DESIGN INPUT
Start with Cooling Capacity, Heat Dissipation or a Drawing
Cooling Capacity
Examples: kW, W, BTU/h, refrigeration load or system capacity target.
Heat Dissipation
Examples: power electronics heat load, compressor heat rejection, cabinet heat gain or process heat removal.
Flow and Temperature
Examples: airflow, liquid flow, inlet temperature, outlet temperature, ambient condition or pressure drop limit.
Space and Structure
Examples: installation space, connection position, cabinet size, mounting direction or old sample dimensions.

SAMPLE DELIVERY STANDARD
Sample Delivery Standards for Rapid Prototyping
Purpose Definition
Confirm whether the sample is for fit-up, concept review, thermal validation, customer presentation or production preparation.
Dimension Review
Key dimensions, connection positions, mounting points and tolerance-sensitive areas should be checked before delivery.
Material Confirmation
Copper, aluminum, stainless steel, coated materials or prototype alternatives should be confirmed according to the project stage.
Test Scope
Clarify whether leakage, pressure, airflow, thermal or appearance review is required for the prototype.
Packaging Protection
Samples should be protected to avoid tube, fin, connector or surface damage during shipment.

PROTOTYPE TYPE COMPARISON
Which Prototype Type Should You Choose?
3D-Printed Fit-Up Model
Best for: space validation, mounting check, structure review and customer presentation. Not for: pressure-bearing final product verification.
CNC Sample
Best for: machined parts, connectors, plates, brackets, small metal structures and dimensional review. Not for: full thermal performance validation unless designed for that purpose.
Functional Coil Prototype
Best for: condenser, evaporator, fin-tube coil or heat exchanger sample validation. Not for: unverified performance claims without testing data.
Appearance / Customer Approval Sample
Best for: visual approval, packaging review, fit-up and early customer discussion. Not for: final production approval without engineering confirmation.
PROTOTYPE TO PRODUCTION
From Rapid Prototype to Repeatable Production
Step 1: Prototype Goal Confirmation
Confirm whether the prototype is for fit-up, appearance, thermal review, customer approval or production preparation.
Step 2: Design Update
Adjust drawing, dimensions, material, tube route, fin structure or connection details according to prototype review.
Step 3: Sample Validation
Review fit-up, appearance, leakage, dimension, thermal condition or customer-specific requirements.
Step 4: Production Feasibility Review
Review tooling, material supply, manufacturing process, inspection method and packaging needs.
Step 5: Pilot Production
Prepare small batch or pre-production review if required before full production.
Step 6: Bulk Production
Move to repeated production after sample approval, specifications and quality requirements are confirmed.
