a, Cold plate configurations conform to server design and functionality. The left panels show a general-purpose server cooled with air (top) or cold plates (bottom). The right panels show a GPU server cooled with air (top) and cold plates (bottom). b, One-phase immersion uses tanks (left) for submersion of servers. The right panel shows a partially submerged server. c, Two-phase immersion also relies on the immersion of servers in a tank, which relies on the boiling of a refrigerant, evident as surface turbulence in the inset.
