A heat dissipation device with forced coolant flow is provided which includes a base, coolant conduits, and a driving module. The conduit includes an inlet port, an extension segment, and an outlet port. The extension segment is connected to the base. The driving module includes a housing, a separating member, and two magnetic driving members. The separating member, being a thin magnetic plate, is positioned in the housing and defines a first chamber and a second chamber for coolant. The first chamber and the second chamber are connected to the inlet port and the outlet port and a flow of coolant can be initiated by alternating an electrical current feed to the two magnetic driving members on each side of the separating member.
