A structure includes a heat dissipation fixing base having through bores formed at four corners thereof, screw fastening elements extended through the through bores for the heat dissipation fixing base to be fixed on and in contact with a heat source, and two spaced upward extended extension arms; a hold-down member disposed on the heat dissipation fixing base and having a pair of openings engaged with the two extension arms to assemble the hold-down member to the heat dissipation fixing base; and an adjustment element including a lever having an outer end formed into an eccentric cam having a shaft hole, and a shaft extended through the shaft hole to pivotally connect the eccentric cam to the extension arms. By swinging the lever, the eccentric cam will press against the hold-down member for the same to evenly apply downward forces on a central area of the heat dissipation fixing base.

An error-unlocking protection structure for heat dissipation base seat includes a heat dissipation base seat, an operation member and a cover body. The operation member has a cam section pivotally connected with the connection section disposed on the heat dissipation base seat. A linking member is disposed between the cover body and the operation member and respectively connected with the cover body and the cam section. When operating the operation member, the cam section is forced to press the heat dissipation base seat and make the heat dissipation base seat tightly attached to the heat generation component and located thereon. At the same time, the linking member is driven to horizontally move the cover body relative to the heat dissipation base seat, whereby the cover body shields locking members to prevent the heat dissipation base seat from being uninstalled from the heat generation component by error.

A structure for evenly applying forces on a heat dissipation base plate includes a heat dissipation base plate having upper and lower surface, a first threaded hole, and through bores provided at four corners thereof, and being held in place on a heat source by screw fastening elements extended through the through bores for the lower surface to contact with the heat source; a hold-down member disposed on the upper surface of the heat dissipation base plate and having upper and lower side and a second threaded hole extending from the upper to the lower side; and an adjustment element including a screw bolt and a turning knob connected to the screw bolt, the screw bolt being extended through the first and second threaded holes, and turnable by the screw bolt to downward press against and apply evenly distributed forces on a central area of the heat dissipation base plate.

A complex vapor chamber structure includes a main body and at least one tubular body. The main body has a first chamber, a first opening and a second opening. A first capillary structure is disposed in the first chamber. A working fluid is filled in the first chamber. The first and second openings pass through one face of the main body to communicate with the first chamber. The tubular body has a first end, a second end and a passage. The first and second ends are respectively correspondingly inserted in the first and second openings, whereby the passage of the tubular body communicates with the first chamber via the first and second ends to form a loop for vapor-liquid circulation.
