Project Title: Create precise 3D CAD model + STEP file for Aluminium Liquid Cooling Plate (V1.1) – CNC ready for prototype
Project Description & Purpose: I need a professional 3D model and STEP file (plus basic 2D PDF drawing) for a liquid cooling cold plate prototype. This is for showing to EV/battery startups in India. The design must be fully machinable on a standard 3-axis CNC mill using Aluminium 6061-T6.
Overall Requirements:
• Software: SolidWorks preferred (or Fusion 360 / Creo / CATIA – any that exports clean STEP).
• Deliverables:
1 Full editable 3D assembly (base + cover) – STEP format (AP214 or AP242)
2 Separate parts: Base plate and Cover plate
3 Basic 2D PDF drawing with all dimensions, tolerances, flatness callouts, and section views
4 Optional: Simple exploded view or rendering for my presentation
Material (Specify in model): Aluminium 6061-T6 for both base and cover.
1. Base Plate Dimensions
• Outer size: Length (X) = 200 mm, Width (Y) = 120 mm, Thickness (Z) = 10 mm
• All outer edges: 1 mm chamfer or 0.5 mm fillet for clean look
2. Internal Cooling Channels (Serpentine with Plenums)
• Channel type: Continuous serpentine (zig-zag) flow path
• Channel cross-section: Width = 6 mm, Depth = 4 mm (milled into the top face, so 6 mm remaining material at bottom)
• Minimum wall thickness between channels: 3 mm
• Number of straight horizontal passes: Exactly 10
• Flow direction: Inlet on top-left → zig-zag left-to-right then right-to-left → outlet on top-right
• Inlet Plenum (top-left): Approximately 40 mm wide (along Y) × 15–20 mm deep (along X) × 4 mm deep – this distributes flow evenly into the 10 channels
• Outlet Plenum (top-right): Same size as inlet plenum
• All turns: Smooth U-bends with minimum inner radius 6 mm (no sharp corners – critical for flow and machining)
• Channel zone: Centered on the plate with ~15 mm border on all sides for sealing and screws
• Surface finish note: Channels should have smooth finish (Ra ≤ 1.6 µm) – mention in drawing
3. Inlet & Outlet Ports
• 2 ports total, located on the top face
• Position: Centered inside each plenum (approx. 20 mm from left/right outer edge, centered in Y direction of plenum)
• Hole: Drill diameter 11.8 mm, then full G1/4 thread (British Standard Pipe Parallel) – depth minimum 8 mm
• Note in drawing: “Drill Ø11.8 mm then tap G1/4”
4. O-Ring Groove for Sealing
• Machined into the top face of the base plate
• Rectangular groove surrounding the entire channel + plenum area (offset 5–8 mm outside the flow path)
• Groove size: Width = 3 mm, Depth = 1.5 mm
• Use for rubber O-ring cord or gasket (this makes the seal leak-proof)
5. Screw Holes
• 16 × M4 socket head cap screws (countersunk)
• Placed evenly around the perimeter, spacing every 25–30 mm
• In base: Tapped holes, depth minimum 8 mm
• In cover: Clearance holes + countersink for screw heads
• Torque note (optional): 3–4 Nm
6. Alignment & Mounting Features
• 4 × locating dowel pins: Ø6 mm × 10 mm long (press-fit into base, slip-fit into cover) – one near each corner but inside the sealed groove area
• 4 × corner mounting holes: Ø6.5 mm clearance holes (for bolting the whole plate to a battery mock-up)
7. Top Cover Plate
• Dimensions: Exactly 200 mm × 120 mm × 4 mm thick
• Material: Aluminium 6061-T6
• Edges: 1 mm × 45° chamfer all around
• Matching holes: 16 × M4 clearance + countersink + 4 dowel clearance holes
8. Critical Manufacturing & Quality Notes (Add to Drawing)
• Mating faces (top of base and bottom of cover): Flatness ≤ 0.05 mm (very important for leak-proof seal)
• Surface finish on mating faces: Ra ≤ 0.8 µm
• All internal channel corners: Fillet ≥ 1 mm
• No sharp edges inside flow path
• Total assembled thickness: ~14 mm (plus gasket)
• Flatness and surface finish callouts must be clearly shown on the drawing
9. Reference Images (Attach the 5 reference images I showed earlier – serpentine cold plates, CFD flow views, exploded assembly, copper tube examples, etc.) Or tell the freelancer: “Search GrabCAD for ‘liquid cold plate’ or ‘serpentine cooling system’ for visual reference. My design has exactly 10 passes + wide plenums at inlet/outlet, G1/4 ports on top face, and O-ring groove.”
10. Additional Instructions
• Keep the design simple and optimized for 3-axis CNC milling.
• All dimensions in mm. Use standard tolerances unless specified (e.g., ±0.1 mm for most features).
• Provide the model in a clean assembly with proper names (Base_Plate, Cover_Plate).
• Timeline: Prefer 1–2 days delivery.
• Budget range: ₹1000 – ₹2500 (negotiable based on experience).
Extra Tips for Freelancer (Optional to add):
• Experience with heat exchangers, cold plates, or liquid cooling systems is a big plus.
• After delivery, I may ask for small changes (e.g., exact port coordinates or more fillets).
• Final STEP file must open cleanly in common CAM software used by CNC shops in India.
