1. A power-module-heat-dissipation assembly comprising:
a plurality of first power modules arranged along a first direction;
a plurality of second power modules arranged along the first direction;
a coolant flow-channel inlet;
a coolant flow-channel outlet;
a first housing base comprising a first flow channel and a first heat dissipation surface; and
a second housing base comprising a second flow channel and a second heat dissipation surface;
wherein the first housing base and the second housing base are matched and assembled with each other to form a housing extended along the first direction and having a first elongated lateral side and a second elongated lateral side opposite to each other, wherein the first heat dissipation surface and the second heat dissipation surface are disposed on two opposite sides of the housing, respectively, the plurality of first power modules are disposed on the first heat dissipation surface along the first direction, and the plurality of second power modules are disposed on the second heat dissipation surface along the first direction, wherein the first flow channel is a hollow structure of the first housing base and comprises a first flow-channel front port, a first chamber and a first flow-channel rear port, the first chamber is in fluid communication with the first flow-channel front port and the first flow-channel rear port, the first chamber is corresponding to an outer surface of the first housing base to form the first heat dissipation surface, the second flow channel is a hollow structure of the second housing base and comprises a second flow-channel front port, a second chamber and a second flow-channel rear port, the second chamber is in fluid communication with the second flow-channel front port and the second flow-channel rear port, and the second chamber is corresponding to an outer surface of the second housing base to form the second heat dissipation surface, wherein the coolant flow-channel inlet is in fluid communication with the first flow-channel front port, the first flow-channel rear port is in fluid communication with the second flow-channel rear port, and the second flow-channel front port is in fluid communication with the coolant flow-channel outlet,
wherein the first flow-channel front port and the second flow-channel front port are disposed adjacent to the first elongated lateral side, and the first flow-channel rear port and the second flow-channel rear port are disposed adjacent to the second elongated lateral side.
