Abstract: According to the analysis of heat transfer characteristics of the data center dual channel cooling system, the feasibility of the data center dual channel cooling system is demonstrated based on the Fourier law of heat transfer. Two experiments were carried out to analyze the two heat transfer characteristics of the dualchannel cooling system: the heat exchange rate of the contact cooling system increases with the decrease of the inner circulating water supply temperature. The energy consumption of non-contact cooling system decreases with the increase of air temperature.
