Abstract
A combination heat dissipation structure includes a vapor chamber and at least one heat pipe. The vapor chamber defines an airtight chamber filled with a working fluid and provided with first and second wick structures. The vapor chamber further includes at least one through hole formed on its upper wall and communicable with the airtight chamber, and at least one annular element provided in the airtight chamber corresponding to the through hole to contact with the first and second wick structures. The heat pipe has an open end inserted into the airtight chamber to contact with the first wick structure, such that the heat pipe is axially supported and located by the annular element. With these arrangements, a flow-back path between the vapor chamber and the heat pipe is largely shortened to avoid dry burning in the vapor chamber and upgrade the two-phase heat exchange efficiency of the vapor chamber.
