Case heat dissipation structure

A case heat dissipation structure, comprising:

• a case comprising an air duct and a plurality of heat dissipation chambers which are stacked and communicated with each other, wherein the heat dissipation chamber at the top layer of the case is in communication with the heat dissipation chamber at the bottom layer of the case through the air duct, heat sources are respectively mounted in each of the plurality of heat dissipation chambers, and a liquid inlet for cooling liquid to flow in and a liquid outlet for cooling liquid to flow out are provided on the case;
• a heat exchange assembly, wherein the heat exchange assembly is mounted in each heat dissipation chamber or the heat exchange assembly is mounted in some of the heat dissipation chambers, each heat exchange assembly comprising a heat exchanger that is arranged between the liquid inlet and the liquid outlet and is communicated through a liquid cooling pipeline;
• a fan assembly, which is mounted in at least the heat dissipation chamber of the bottom layer, wherein the fan assembly is used for driving the air in the heat dissipation chamber of the bottom layer of the case to be transported to the heat dissipation a chamber of the top layer and subjected to heat exchange treatment through the heat exchangers, and driving the air in the heat dissipation chamber at the top layer of the case to flow back to the heat dissipation chamber at the bottom layer of the case through the air duct in operation,
• wherein, a plurality of liquid cooling plates or isolation plates spaced apart are mounted in the case to form the plurality of heat dissipation chambers;
• and
• both ends of the liquid cooling plate or the isolation plate are respectively provided with an air return port.
