To address the current problem of high energy consumption in data centers, this paper proposes a center heat pipe air-conditioning system based on latent water evaporation, which uses evaporation for cooling by creating low pressure environment to evaporate large amounts water. In order verify effect system, test bench was designed and built. Compared with traditional dissipation, performance e...
