LFP Blade Battery Side Cooling System Water Brazing Cold Plate for Electric Cars 

A sound cooling system can not work well without a qualified cooling medium, and aluminum is chosen as the main material owing to its high thermal conductivity, usually it will be shaped into various end-products through different technologies, like stamping, casting, extruding and so on.


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?
