Radial heat sink device

Abstract

A radial heat sink device includes a central heat conduction member, a plurality of heat sink fins and at least one curved heat conduction pipe. The plurality of heat sink fins are radially disposed around the central heat conduction member and each has a portion connected to an outer peripheral wall of the central heat conduction member. Each of the heat sink fins has a recess disposed at an upper end or a lower end thereof. The curved heat conduction pipe is tightly connected to the bottom of central heat conduction member and flush with the bottom of central heat conduction member and positioned in the recess of each of the heat sink fins. The radial heat sink device has the at least one heat conduction pipe which is flush with the bottom of the central heat conduction member to contact with the heat source.
