On the other hand, servers in the cabinet are generally stacked from top to bottom. If the liquid supply interface has pressure loss of different degrees in the process of providing circulating liquid for each layer of server, the heat dissipation effect of each layer of server is seriously affected due to different liquid supply amounts, different heat dissipation temperatures and different heat dissipation efficiencies.
