Patent ID: 8226454

Claim:
A heat dissipating architecture for a machine tool, comprising: a machine tool, including an accommodating space, a tool shaft held in the accommodating space, a counter balancing mass mounted on the tool shaft and an inlet communicating with the accommodating space, wherein the counter balancing mass includes a first balancing portion and a second balancing portion for causing the tool shaft to generate an eccentric rotation stroke relative to the machine tool; and a heat sink, which is mounted on the counter balancing mass and synchronously rotated with the tool shaft, including a first blade portion corresponding to the first balancing portion, a second blade portion corresponding to the second balancing portion, and a linking portion for connecting the first blade portion and the second blade portion together, such that during the rotation stroke of the tool shaft, the heat sink inhales air via the inlet, transmits the air from the first blade portion to the second blade portion, and then exhausts the air from the second blade portion.
