1. A liquid cooling plate assembly, configured to be in thermal contact with two first heat sources and a plurality of second heat sources, the liquid cooling plate assembly comprising:
a first liquid cooling plate, comprising:
a first heat dissipation part, configured to be in thermal contact with one of the two first heat sources and having a first fluid chamber; and
at least one second heat dissipation part, integrally connected to the first heat dissipation part and configured to be in thermal contact with some of the plurality of second heat sources, wherein the at least one second heat dissipation part has at least one first fluid channel;
a second liquid cooling plate separated from the first liquid cooling plate, the second liquid cooling plate comprising:
a third heat dissipation part, configured to be in thermal contact with another one of the first heat sources and having a second fluid chamber; and
at least one fourth heat dissipation part, integrally connected to the third heat dissipation part and configured to be in thermal contact with others of the plurality of second heat sources, wherein the at least one fourth heat dissipation part has at least one second fluid channel, and the at least one second fluid channel is in fluid communication with the second fluid chamber;
a first connection tube, connected to the third heat dissipation part and the first heat dissipation part so as to communicate the second fluid chamber with the first fluid chamber; and
at least one second connection tube connected to the at least one fourth heat dissipation part and the at least one second heat dissipation part so as to communicate the at least one second fluid channel with the at least one first fluid channel,
wherein the liquid cooling plate assembly is configured with a coolant flow path that flows sequentially flows through the first fluid chamber of the first heat dissipation portion, the first connection tube, the second fluid chamber of the third heat dissipation portion, one of the at least one second fluid channel of the at least one fourth heat dissipation portion, one of the at least one second connection tube, and one of the at least one fourth fluid channel of the at least one second heat dissipation portion.
