Q-CHILL™ Coldplates

High Performance Liquid Cooling

Invented by MaxQ Technology, Q-CHILL™ Coldplates are used in thermal management applications for industries in renewable energy, wind turbines, high-speed rail, solar, electric vehicle, military, and large industrial drives. This innovative technology provides uniform cooling of power electronic devices from 30kW to 250kW. Manufactured using the friction stir welding (FSW) process to incorporate unique cooling structures, Q-CHILL™ Coldplates have great thermal performance with low pressure drops.

Patented internal fin technology that provides more uniform coldplate surface temperatures

Low-cost proven aluminum solution (with performance comparable to copper-based solutions)

Friction stir welded (FSW) joints that are leak-proof and a high-pressure rated

Exceptional heat rejection on coldplate surfaces

Low pressure drops that reduce the need for large fluid pumps

Dual-sided cooling capability and very large coldplate size

Compatibility with industry accepted coolants

Q-CHILL™ Coldplates are used

in applications such as:

  • Electric vehicle motor drives
  • Wind turbines
  • Solar inverters
  • Industrial motor controls
  • Power converters

Standard IGBT Module

Q-CHILL™ Coldplates

Available as “off the shelf” products, our standard aluminum Q-CHILL™ coldplates meet standard IGBT power module footprints manufactured by Infineon, Semikron, PowerexMitsubishi Electric, and Fuji Electric. Our coldplates are compatible with standard cooling fluids used in most applications, including ethylene glycol and water solutions (EGW), dielectric fluids such as Flourinert™ and oils. Low pressure drops may be achieved with high thermal dissipation.

Wind Turbine Coldplates

MaxQ Technology’s Q-CHILL™ Coldplates are now available for wind turbines, providing solutions for 500 kW to 4 MW power conversion applications. Our unique process allows uniform cooling of up to 18 large IGBT power modules.

Starting with your specifications, MaxQ Technology develops effective thermal management solutions, providing the best performance, reliability, and weight at the best possible price, including functional prototypes and support for global volume production needs with full ISO Quality Standards and Certifications.

Large Power Module Coldplates

Q-CHILL™ Coldplates can be developed to cool the following large power module packages:

  • PrimePACK2
  • PrimePACK3
  • HiPak 1 (140 x 130)
  • HiPak 2 (140 x 190)
  • MEGA DUAL
