Claim 1:
2. The heat dissipation device according to claim 1, wherein
the first heat dissipator includes:
a first cooling pipe through which the coolant passes, the first cooling pipe extending in the first direction; and
a first fin that is in contact with an outer peripheral surface of the first cooling pipe and extends in a second direction orthogonal to the first direction;

the second heat dissipator includes:
a second cooling pipe through which the coolant passes, the second cooling pipe extending in the first direction; and
a second fin that is in contact with an outer peripheral surface of the second cooling pipe and extends in the second direction;

the first heat dissipator and the second heat dissipator are arranged in the second direction;
the first tank is divided by a first partition into a first tank chamber connected to the tank-side first inflow port and a second tank chamber connected to the tank-side first outflow port; and
the second tank is divided by a second partition into a third tank chamber connected to the tank-side second outflow port and a fourth tank chamber connected to the tank-side second inflow port.
