High Density Fin

Lytron’s liquid cold plates are now available with high density fin, a technology that can help achieve improved thermal performance and ultimately enable reductions in cooling system size, weight and cost.

Fin density can be defined as the number of fin rows per unit length, and fin is typically available in densities of 6-11 fins per centimeter.

Lytron has increased its fin density by over 3X, and is now fabricating fin up to 35 fins per centimeter. Due to the challenges with fin pitch, high density fin architecture is currently available in the straight-line configuration.

Lytron has extended its extensive customization capabilities into its high density fin family, and it can be mixed with standard density fin in hybrid configurations for both liquid cold plates and chassis.

Some of the key advantages for Lytron high density products are:

  • High thermal performance
  • Weight savings up to 50%
  • Tighter surface temperature control
  • Improved cooling system efficiency
