Simuation Aided Flow Path Design Liquid Cooling Plate for EV 

With the increasing energy density of the instruments, Liquid cooling system is becoming more and more prevalent. Liquid cooling system fully leverage the high heat capacity of the liquid, which absorbs and transports the heat at a high rate.  Very efficiently, as compared to air cooling or solid conduction.  Liquid cooling system can  solve the heat problem that can not be solved by traditional air cooling systems. And also its cost is continuously decreasing because of maturer production process. Undoubtedly it is becoming a most compact sustainable, cost effective and efficient method to cool high density heat loads.

Liquid cooling system can not work without well-developed aluminum cold plates. Has been in heat exchange material for so many years, Trumony is capable of tailoring a suitable cooling solution for you.


Item EV battery liquid cold plate
Thickness Per your request  / 5~8mm
Width/Length It depends on your battery pack 
Surface treatment Zinc Spray, Insulation coated, Bare
Structure Passenger channel plate, bottom cold plate, inlet/outlet 
Process  Cold stamping - cleaning - spray flux - fixture clamp the product into the brazing furnace - brazing furnace after more than a dozen procedures (automatic heating/insulation/cooling/welding, etc.) - do full inspection of air tightness test - cleaning (mainly for welding cleaning, polishing, drying) a total of more than 20 procedures
Test  Leakage test, pressure test, burst test and etc. 

liquid cooling plate


*Design options:

1) Punching cooling plate

It used for prismatic cells and battery pack, bottom & side cooling solution;

2) Serpentine cooling ribbon

Applied for cylindrical cells: 18650, 21700, 3270, 4680 and etc;

3) Micro-channel tube with manifold

For battery pack side or bottom battery cooling;

4) Roll bonding cooling plate;

5) Friction stir welding plate

It has a simpler welding process, higher production efficiency, higher weld strength, and can avoid problems such as pores and liquid leakage in high-temperature fusion welding.

* Customized plate size and flow channel path

1) Design your liquid cooling plate according to battery pack boundary size;

2) Optimization flow path as the result of flow field simulation;

* One-stop service package

1) Design service: thermal simulation, flow field simulation, prototype making;

2) Online meeting technical support;

3) Sample fast dispatch.


Q: How long does it take for samples and mass production?

A: Usually it will take 15-20 days for new moulds and free samples (within 5kg), after confirmation, 25-30 days for mass production.

Q: OEM/ODM available?

A: Yes,we can!

Q: Can you assist in design?

A: Yes, we can! We have a strong and experienced design team.

Q: Could you provide sample?

A: Yes, We are honored to offer you samples for quality check.

Q: Is sample order accepted?

A: Yes,we accept sample order and we can provide design service!
