Abstract：
According to the high-density trend of datacenters, puts forward the rear door heat exchanger solution. Taking a specific project with high density reaching 35 kW/Rack for example, analyses and compares the rear door heat exchanger solution with traditional in-row solution from aspects of initial investment, floor space, PUE, energy consumption. Draws the conclusion that rear door heat exchanger solution has many advantages. Finally prospects the application of rear door heat exchanger solution for high-density datacenters.
