Types of Rear Door Heat Exchangers

  • Passive (up to 30 kW of cooling) — No fans except the server fans are used in the system
  • Active (up to 50 kW of cooling) — High-efficiency fans are used as part of the system
  • Microchannel (up to 20 kW of cooling) — Microchannel heat exchangers use a pumped refrigerant that removes heat more efficiently than water
