NEV battery welding and its cooling system

2022-09-15

New energy vehicle is green and pollution-free, and will develop rapidly in the next few years. The structure of automobile power battery covers a variety of materials, and the requirements for welding are very high. The assembled power battery needs to pass the leak test, and the battery with an unqualified leak rate will be rejected. Laser welding can greatly reduce the defect rate in power battery manufacturing.The mainly used of battery products are copper and aluminum. Both copper and aluminum transfer heat quickly, the reflectivity to the laser is very high and the thickness of the connecting piece is relatively large, a kilowatt-level high-power laser is often used. The kilowatt-class laser needs to achieve high-precision welding, and the long-term operation requires very high heat dissipation and temperature control. S&A fiber laser chiller adopts dual temperature and dual control method to provide a full range of temperature control solutions for fiber lasers. At the sa...

About S&A Chiller

S&A Chiller was founded in 2002 with many years of chiller manufacturing experience, and now is recognized as a cooling technology pioneer and reliable partner in laser industry. S&A Chiller delivers what it promises - providing high performance, highly reliable and energy efficient industrial water chillers with superior quality.

Our recirculating water chillers are ideal for a wide variety of industrial applications. And for laser application in particular, we develop a complete line of laser water chillers, ranging from stand-alone unit to rack mount unit, from low power to high power series, from ±1℃ to ±0.1℃ stability technique applied.

The water chillers are widely used to cool fiber laser, CO2 laser, UV laser, ultrafast laser, etc. Other industrial applications include CNC spindle, machine tool, UV printer, vacuum pump, MRI equipment, induction furnace, rotary evaporator, medical diagnostic equipment and other equipment that requires precise cooling.
