The present application discloses a liquid cooling box and a container-type cooling system. After a plurality of servers and other electronic devices are densely arranged in a liquid cooling chamber, the coolant input through the liquid inlet is dispersed and homogenized for the first time through the diverter chamber and then passed into the liquid inlet chamber from the liquid delivery port for diffusion. When the coolant passes through each liquid inlet hole and enters the liquid cooling chamber, a plurality of coolant jets with similar flow rates and velocities can be formed due to the reduced flow area. Thus, the servers and other electronic devices at various positions in the liquid cooling chamber can obtain more equal coolant injection opportunities when working. In this way, after the coolant enters from the liquid inlet, it passes through the diverter chamber and the liquid inlet chamber for multiple dispersions and homogenizations in sequence, so that the heat dissipation and cooling effects of each server and other electronic devices are close to the same, so as to reduce the risk of causing a local server to stop working due to high temperature.

Data center cooling is one of the key technologies to ensure continuous and stable operation of the electronics within the data center. Because electronic devices such as servers, storage devices, network hardware and the like can generate a large amount of heat during operation, if the electronic devices are not controlled, the devices can overheat, performance is affected, and even the devices are damaged.

In this way, after a plurality of electronic devices such as servers are densely arranged in the liquid cooling cavity 11, the cooling liquid input through the liquid inlet 22 is dispersed and homogenized for the first time through the diversion cavity 21, then is led into the liquid inlet cavity 31 from the liquid feeding port 32 for diffusion, and then enters the liquid cooling cavity 11 through each liquid inlet small hole 13, a plurality of cooling liquid jet flows with similar flow and speed can be formed due to the reduction of the flow area, so that more equal cooling liquid injection opportunities can be obtained when the electronic devices such as servers in each position in the liquid cooling cavity 11 work, and the cooling liquid can be led to have more uniform heat dissipation and cooling effects through the diversion cavity 21 and the liquid inlet cavity 31 after entering from the liquid inlet 22 in sequence, so that the risk of causing the local server to stop working at high temperature is reduced.
