Double Side Inflated Aluminium Roll-Bonded Evaporator Liquid Cold Plate

Aluminum inflated Roll Bonded liquid cold plates are generally made of two spaced thin aluminum sheets, (laser) welded to each other.  The space between the plates is pressurized to deform one or both plates in order to provide a space in which a cooling medium can circulate.
Once the two thin sheets are laser welded together - (by welding a custom circle pattern) - spot welds are then created to form channels. Additional welding paths are often added to allow adjustments and to control direction and velocity which optimizes the cold plate.

Key process

preparing materials – cleaning – printing – rolling – annealing - blowing up – punching –folding and sharpening –adding the capillary – assemble welding – leakage testing –  cleaning and drying – coating - inspection – packing


Application of the aluminum roll bonded evaporator

1-Domestic and Commercial Refrigeration: Evaporators for static refrigerators and freezers & Condensers

2-Thermodynamic Heat Pumps:Solar Evaporators & Condensers for boilers and water tanks

3-Climatization:Radiant ceilings & Radiant walls

4-Electronics and Automotive:PCB cooling frame &Box water cooling & Battery cooling & Surface heat exchangers

1) Surface treated with powder painting to prevent the corrosion
2) Inner cleanness can meet the requirement of R134a & CFC cooling system.
3) Can satisfy the cooling capability requirements
