Therefore, how to quickly remove the heat generated by the data center is particularly important.
At present, a traditional data center machine room generally adopts a method for installing an air conditioner to dissipate heat, and although the method can effectively solve the heat dissipation problem of the data center, the air conditioner must be continuously turned on throughout the year, so that the consumed electric quantity is very large. According to statistics, the traditional data center adopts an air conditioner heat dissipation method, the electric quantity consumed by the air conditioner can reach 40% -50% of the electric quantity consumed by the whole machine room at most, and more seriously, the electric quantity consumed by the air conditioner is not directly acted on key electronic components directly heated in a server, but is mostly wasted in the machine room environment. For such problems, researchers have proposed using a water-cooled heat pipe heat dissipation method to dissipate heat from key heat-generating chips of the server. Although the method can realize direct heat dissipation of key components of the server, the method brings additional problems, namely when the water-cooled heat pipe adopted at present dissipates heat, a water-cooled pipeline can be blocked due to water quality or water scale in the long-term circulating flow process, more seriously, the heat pipe directly contacts the chip to dissipate heat and does not adopt a redundant design or a backup design, once the heat pipe module fails or breaks, the heat of the chip cannot be timely transferred to the water-cooled end of the heat pipe, and the heat of the chip rises instantly and even causes the failure of the whole server.
