Custom CNC Machining of EV Cooling Plate Support Frames

When it comes to electric cars, keeping batteries cool is key. Cooling plate support frames help control heat effectively. Custom CNC machining is important for this job. It ensures accuracy and helps meet tight requirements for better cooling. For example:

  1. Using less ethylene glycol cools better in hot weather.

  2. Air cooling works well for small batteries since it uses less energy.

  3. Mineral oil cooling uses more energy but cools big systems better.

These examples show why custom designs matter. With custom designs, you can improve cooling for any electric car setup.


Material Selection for EV Cooling Plate Support Frames

Common Materials and Their Properties

Picking the right material for EV cooling plate support frames is very important. Different materials have special features that affect heat control, strength, and cost.


Cooling Plate TypeMax Temp Drop (K)Avg Temp Drop (K)Surface Temp Variation Drop (K)
Topological Cooling Plate (TCP)10.077.022.70
Rectangular Cooling Plate (RCP)8.686.062.30


Topological cooling plates work better than rectangular ones. They lower surface temperature changes more effectively. This helps batteries work well and last longer. Aluminum alloys and non-metal composites are popular choices. They balance heat transfer, lightness, and resistance to rust.

Thermal Conductivity and Weight Considerations

Heat transfer and weight are key for EV cooling systems. Lighter materials make cars weigh less, saving energy. Good heat transfer prevents overheating and keeps systems running smoothly.

  • Best setups for battery cooling systems include:

    • PCM thickness = 1.7

    • Air gap = 2.37

    • Air speed = 0.93

    • PCM type = PEG(1000)

This design cuts costs by 91% compared to older systems. It also fits 20% more battery cells, boosting power without losing cooling ability.

Advantages of Corrosion-Resistant Materials

Rust-proof materials help EV cooling plate support frames last longer. Aluminum alloys are great because they naturally resist damage from the environment.

Aluminum alloys are strong, easy to machine, and weld well. They are perfect for custom CNC machining. Non-metal plates are another option. They cost less and resist buildup, improving heat control while staying affordable.

Tip: Using rust-proof materials makes frames last longer and lowers repair costs.


Custom CNC Machining Techniques for EV Components

High-Precision Machining Methods

Making EV parts needs very accurate machining. This ensures parts fit perfectly and work well. Advanced methods like superfinishing make surfaces smoother and sizes more exact. For example:

  • ZF Friedrichshafen uses superfinishing to improve e-transmission shafts.

  • This method makes EVs quieter by reducing noise.

  • It also improves surface quality and size accuracy for e-drive parts.

These techniques help EV parts last longer and work better. Using precise machining ensures EV components meet modern vehicle needs.

Achieving Tight Tolerances and Durability

Exact measurements are key for EV parts to work under tough conditions. Custom CNC machining achieves these precise sizes. The table below shows how accurate different methods are:


TechniqueTolerance Level
CNC Femto Laser Machining+/- 0.001mm to +/- 0.010mm
High Precision Machining±0.0005 inches (0.0127 mm)
General CNC Machining±0.001 inches


For parts like pistons and gears, tight tolerances make them strong and reliable:


ApplicationTolerance Level
Engine Pistons±0.001 inches
Transmission Gears±0.001 inches


Custom CNC machining ensures EV parts are tough and efficient, even under stress.

Advanced Features Like Threading and Tapping

Threading and tapping make EV parts easier to assemble. These processes create strong threads for connecting parts. New ideas have made threading even better. For example:


FeatureDescription
Tool CoatingsSpecial coatings make tools last longer and resist heat.
Chip-Breaking TechnologyEmuge CBTz tech stops chips from clogging tools during threading.
Tap GeometryDifferent tap shapes work better with certain steel types.
Tapping ApplicationsRigid tapping improves thread quality and tool life.


These features make assembly easier and parts more reliable. Custom CNC machining adds these features with great accuracy for EV needs.


Quality Checks in Custom CNC Machining

Testing for Size and Smoothness

Making sure parts are the right size is important. Smooth surfaces also matter for EV parts. Special tests help keep parts consistent and high-quality. Statistical Process Control (SPC) watches for changes during production. Tools like CMMs, laser scanners, and vision systems measure sizes accurately. For smooth surfaces, profilometers and touch tests check quality.


Test TypeWhat It Does
Statistical Process ControlTracks production data to find problems early.
Size Measurement ToolsUses CMMs, laser scanners, and vision systems for exact measurements.
Surface Smoothness TestsChecks smoothness with profilometers and touch methods.
Quality StandardsFollows rules like ISO 9001:2015 and IATF 16949 for better results.


These tests make sure every part works perfectly in EV cooling systems.

Following Rules for EV Parts

EV parts must meet strict rules to be safe and reliable. Makers follow laws like RoHS to avoid harmful materials. They also meet OEM rules to get their parts approved.


Rule TypeWhat It Means
Safety LawsTests parts to follow safety rules and avoid recalls.
OEM RequirementsMeets car maker rules for part approval.
Quality SystemsBuilds strong checks to keep meeting standards.


Regular checks and following global rules like IEC and UL improve trust and safety.

Reliable Parts Through Careful Checks

Careful checks make sure EV parts work well. First Article Inspection (FAI) tests if parts are made correctly. It finds problems early to save time and money.

  • FAI checks parts against designs and customer needs.

  • Early fixes stop recalls and build customer trust.

  • Companies using FAI make safer and stronger products.

By doing these checks, EV parts stay high-quality a


Benefits of Custom CNC Machining for EV Applications

Custom designs for better cooling

Custom CNC machining helps make cooling frames that fit EV needs. These designs improve cooling by guiding coolant flow and keeping battery temperatures steady. Research shows curved channels can lower the highest temperature from 48.73 °C to 30.75 °C. The temperature difference is only 3.98 °C. This keeps batteries cool and makes them last longer.

Chavan et al.Curved channel cooling48.73 °C to 30.75 °C3.98 °CBest cooling method for EVs
Wei et al.Multi-branch LCPN/AN/ABetter cooling balance, fewer hot spots


Other systems, like multi-inlet cooling plates, improve cooling balance. These setups solve specific EV cooling problems with custom designs.

Improving cooling and saving energy

Custom CNC machining helps EV cooling systems work better. It allows precise designs that transfer heat well and use less energy. Lightweight materials and smart cooling setups reduce strain on the car’s power system.

For example, multi-branch cooling plates spread coolant evenly. This stops overheating and protects battery cells from damage. Custom CNC machining makes parts that fit perfectly into EVs. This improves cooling and boosts overall performance.

Real-world success stories

Custom CNC machining has worked well in real EV projects. One example is making 500 aluminum sensor mounts for an EV company. These mounts needed exact sizes and smooth surfaces for accurate readings. The project showed how CNC machining meets EV industry needs with high-quality parts.

This proves how important precision and custom designs are for EVs. Working with skilled CNC machining expertscan help you get the same great results. This ensures your EV parts are strong and perform well.

Picking the right materials, using precise tools, and checking quality are key for making good EV cooling plate support frames. The right materials help control heat and last longer. Studies show mixed designs can cut weight and save money while staying strong. Accurate machining makes parts fit perfectly, which is important for light EV parts like batteries and power systems.

Note: Special lightweight plastics work better than metals in batteries. They are safer and perform better.

Custom CNC machining helps improve EV technology by creating custom designs and dependable parts. Working with skilled machinists ensures your EV parts meet rules and work their best.
